Electro magnetic waves

05-02-2015 Radio waves Radio waves are used for communication & broadcasting For eg. FM transmissions use the frequencies from 88MHz to 108 MHz, communications use 4000-6000 MHz & 11000-14000 MHz generally & so on. Mobile service providers also use the radio waves normally in the range of 900-1800 MHz Spectrum allocation & auction • Two operators cannot use the same frequency in the same region as there will be interference btw each other & both the services will get affected • Same frequencies can be used at two different places separated by sufficient distance so that there will not be any interference. This is called space diversity • The number of voice channels that can be supported depends on the bandwidth of the frequency spectrum allocated. Higher the bandwidth, more the number of channels that can be accommodated • This radio frequency spectrum is a limited resource & different services are allocated different frequencies • So basically the users are allocated a band of radio frequencies for their service & this radio frequency band is called spectrum • The operators use these frequencies to provide service & earn revenue. As revenue earned will be high there will be competition to get frequency band & hence auction is done with some regulations • For eg. private FM operators use the FM band , provide radio service & earn revenue from the advertisements. 150KHz bandwidth is sufficient for one FM station as so many FM stations can exist in the 88-108 MHz band allotted for FM radio service

01-05-2014 Difference btw Induction stove & microwave oven

• What is difference btw working principles of microwave oven & induction stove? Why are only stainless steel vessels preferred for the induction stove instead of copper, brass and aluminium, which are good conductors of heat? • In case of microwave oven, microwaves which are of low wave lengths (about 12 cm) but contain high energy, are produced through a device known as magnetron. The microwaves are reflected on to the cooking vessel where the food is stored • The high energy microwaves vibrate the of the food at very high frequency (2500,000000/sec) which in turn produces high quantity of heat energy. The heating of food is more uniform as compared to other methods. • However, only non metallic containers can be used to store food inside the oven as metallic containers are likely to reflect back the micro waves • Also one has to take extra precautions while using the microwave oven as the high energy waves can harm the living cells of the body • In case of an induction stove, the heat energy is produced through induction effect. There is an electric coil below the top of induction stove. When varying (alternating) electric current is passed through the coil, a magnetic field is produced around it • When a steel or any other ferro-magnetic metal vessel is kept on the top of the induction stove, it produces eddy electric current in the vessel itself. Due to resistivity of the metal, when the electric current is passed in the vessel, it produces heat energy (as produced in an electric heater) which in turn heats up the food. However, limitation of the induction stove is that vessels which are of non ferromagnetic metal like copper, aluminium, or of glass cannot be used as there will be no eddy current in them

08-05-2014 What makes stainless steel non-magnetic whereas ordinary steel and iron are magnetic? We have to first understand how magnetic fields are generated around magnetic metals to answer this question. We know that within each , spin on their axis that, in turn, causes magnetic field around them. Some electrons spin clockwise, some counter-clockwise. Generally they are paired so that the magnetic fields are cancelled. Iron which is a magnetic substance has three unpaired electrons. Each generates a magnetic field of its own. If all the fields pull in the same direction then you have a magnet. In other words, the magnetic fields are aligned in a magnet. In the case of stainless steel, there are several types of them. In general they are made of iron (Fe), carbon (C), and about 10 per cent chromium (Cr). Some contain Nickel (Ni). But other metals are added to obtain different properties. As stainless steel contains iron, a magnetic metal, one it would seem that it would be magnetic. However, when nickel (Ni) is added to stainless steel the result is a nonmagnetic form of stainless steel, called austenitic stainless steel. At the atomic level, all the iron act as mini magnets that are aligned in the same direction. The net effect of this is that collectively the magnetic properties of all the iron atoms add up to produce the overall magnetisation of the material. This is known as ferromagnetism. But the addition of other elements to iron changes the properties. For instance, when chromium and nickel are added, the arrangement of atoms changes completely and this, in turn, affects the magnetic properties of iron. The nickel and chromium that are added to iron tend to cancel the magnetic fields and the net outcome is that stainless steel becomes a non-magnetic substance.

100 yrs of Einstein's theory of relativity

26-11-2015 • On Nov. 25, 1915, he set down the equation that rules the universe • General theory of relativity describes space-time as a kind of sagging mattress where matter & energy, like a heavy entities, distort the geometry of the cosmos to produce the effect we call gravity • Space-time could curve, fold, wrap itself up around a dead star & disappear into a black hole. It could even rip or tear. It could stretch & grow, or it could collapse into a speck of infinite density at the end or beginning of time • The theory transformed our understanding of space & time

27-11-2015 Dr.Tilak HR 100 yrs of Einstein's theory of relativity • General relativity sees gravity as what is experienced when mass wrinkles the space-time continuum Special theory of relativity • In special relativity, the only constant is the speed of light in a vacuum • The time depends on the speed at which your frame of reference is travelling. The faster you go, the slower time passes & this is not an illusion • The frame of reference can be the bicycle you’re riding, or the planet that the bicycle is traversing, or the system, or the galaxy, or the universe? If we live in a multiverse, our universe can be read as just one inertial frame of reference among many, all in relative motion

27-11-2015 Dr.Tilak HR 100 yrs of Einstein's theory of relativity • Einstein Field Equations (10 equations) ended the age of Newtonian physics & changed our perception of reality • Einstein won the Nobel Prize for explaining the photoelectric effect ○ The Photovoltaic cells on Solar panels use this principle • His theory of relativity is based on 2 notions: that the basic laws of the universe remain invariant in all inertial frames of reference, & that the speed of light in a vacuum is a constant for our universe • Special relativity reconciled the divergence, near the speed of light, btw the results predicted by Newtonian physics & James Clerk Maxwell’s laws of electromagnetism • General relativity finds gravity to be the effect of mass on the fabric of space-time, causing warps & wells • The most stirring prediction of general relativity was black holes (gravity wells created by superdense bodies from which even light cannot escape)

02-12-2015 Dr.Tilak HR Einstein: the most admired legend of science, his theories of relativity & applications Special theory of relativity • 1 of the 5 pathbreaking papers produced by Einstein unveiled the special theory of relativity in the year 1905 • The special theory of relativity stated that due to the constancy of the speed of light for all observers (& nothing can exceed the speed of light), the notions of time & space depend on one’s state of motion • One consequence of this is that the mass of any object is given by its total energy divided by the square of the speed of light. This is the equation E=mc2 General theory of relativity

General theory of relativity • A decade later, in Nov 1915, Einstein presented his general theory of relativity • It completely capsizes our understanding of Newtonian gravity • The general theory of relativity tells us that gravity should be understood as warps & curves in mutative space-time ○ This is fundamentally different from the Newtonian gravity where it is an attractive force btw two objects ○ In general theory of relativity, space & time lose their separate & absolute existence & become, with the meshing of the 3 dimensions of space with 1 dimension of time, a single flexible fabric of pure geometry . The fabric sags in the presence of massive objects of matter . When an object falls, it is simply stretching & creating a dip in space-time . In other words, curved space-time tells matter how to move; matter tells space-time how to curve Applications & validations of Einstein’s theories of relativity • The satellite-based & precision-intensive global positioning system (GPS) applies the knowledge provided by both special & general theories of relativity ○ GPS technology takes into account the fact that the curvature of space-time is less high above than it is at the Earth’s surface, where gravity is stronger ○ It is the reason why clocks onboard run faster than clocks on the ground • General relativity explains all gravitational phenomena, from the smallest (falling apples) to the largest (escaping galaxies) • Einstein’s prediction that light from a star is bent by the gravitational field of the sun has been validated • It has helped explain the discovery of black holes (objects so dense that even light cannot escape their gravity) • It has also provided a framework to discuss the cosmos & aided scientific affirmation of two other fantastic celestial facts: the big bang (birth of our universe) & also its subsequent expansion at an accelerated pace • Einstein’s theory predicted the existence of gravitational waves whose discovery will provide an unprecedented view of the universe ○ India has a unique opportunity to participate in a high-profile international experiment, called Ligo (Laser Interferometer Gravitational Wave Observatory), to observe these waves Einstein advocated nuclear disarmament & world peace • He interacted with 3 of India's greatest contemporary Indians — Mahatma Gandhi, Rabindranath Tagore & Jawaharlal Nehru • The basis of their affinity & admiration was their common commitment to a world without violence • One of Einstein’s lasting legacies was his leadership, along with Bertrand Russell, in issuing the Russell-Einstein Manifesto for nuclear disarmament & world peace • He advocated progressive ideals, socialism being one of them

30-11-2015 Dr.Tilak HR Einstein's theories of relativity helped understand universe & humanity's place in it • Albert Einstein published 10 equations of his general theory of relativity which set out a new concept of gravity—not as its own, independent force, but as the warping of the fabric of space & time in the presence of mass • It predicted, & then helped explain, the black holes that have captured public imagination • Efforts to join relativity with , in a field called string theory, are shedding light on science including materials that conduct electricity without resistance & new kinds of information processing • Relativity has set the stage for what is known as “precision cosmology” ○ Exceptionally detailed theory lined up with ever-better observational data to furnish predictions about physical phenomena far away both in space & in time ○ Where once satellites & telescopes were deployed to scan for new sources of light, these instruments began to look to the dawn of the universe, & examine its frontiers with astonishing precision • Relativity had become to describing the Big Bang ○ Researchers can speak with increasing authority of what happened in the earliest fractions of a second in the universe’s history, & what might happen at its end • It provided a way to satisfy one of the most fundamental questions: to understand what is out there in the universe, how it all began & humanity’s place in it

Scientific developments 24 February 2014 20:18 It was the year in which an object from the cosmos burned and boomed its way through our atmosphere while one originating on Earth hurtled into the uncharted territory of interstellar space. Fire in the sky

On 15 February, skywatchers were gearing up for the close flyby of Earth by a large asteroid. But on the day of that pass, a different 10,000-tonne space rock burned up over Chelyabinsk, , injuring more than 1,000 people as its shockwave shattered glass and rocked buildings.

This spectacular "cosmic coincidence" gave scientists anunprecedented opportunity to study the anatomy of an asteroid strike, in part thanks to the dashboard cameras - dashcams - installed by Russian drivers to combat insurance scams and police corruption. The largest chunk of the meteorite was later retrieved from the bottom of Lake Chebarkul.

The BBC's Daniel Sandford says people described a ball of fire in the sky

Interstellar species

In March, scientists had outlined their results showing that Nasa's Voyager-1 spacecraft had left the heliosphere - the bubble of hot gas from our Sun - in August 2012. But officials from the space agency quickly countered the claims. By September, the outlook had changed, and mission scientists published their own evidence - incorporating additional data - confirming the probe's entry into the region between stars.

data - confirming the probe's entry into the region between stars. Though a handful remain doubtful, Voyager-1 - launched in 1977 to study the outer planets - appears to be the first manmade object to reach interstellar space. Dangerous download

In May, BBC News broke the story of the world's first 3D printed gun being successfully fired in the US. A controversial group tested the weapon at a firing range near Austin, Texas. Designer Cody Wilson, who described himself as a crypto- anarchist, said he was "seeing a world where technology says you can pretty much be able to have whatever you want". The blueprint used to produce the plastic gun had been downloaded about 100,000 times in just under a week after it went online. The US government later demanded that blueprints for the firearm be removed from the web, amid criticism from anti-gun campaigners. Watch the skies

One advance in physics this year has the potential to spawn a new branch of astronomy. In May, the BBC News website was first to report that the IceCube experiment, buried in the ice at the south pole, had seen high-energy particles streaming in from outside our Solar System. While existing branches of astronomy make use of different wavelengths of light, such as optical or infrared, this development makes it possible to picture the cosmos using particles. And there were delights for cosmologists, as a spectacular map of the oldest light was assembled from data gathered by the telescope. Tough climate

In September, a UN panel of experts released its long-awaited report detailing the physical evidence behind climate change. The scientists working with the Intergovernmental Panel on Climate Change (IPCC) said they were 95% certain that humans had been the "dominant cause" of global warming since the 1950s. Despite this, and projections suggesting 2013 could be among thewarmest years on record, the political process to reduce emissionsremained precarious. And the warming "pause" continued to stump climate scientists, with the ban

reduce emissionsremained precarious. And the warming "pause" continued to stump climate scientists, with the ban on CFC gases and natural cooling in part of the Pacific ocean among the reasons proposed. Nanotubes and 'spooky action'

A team of scientists at unveiled the first computer made of carbon nanotubes in September. The device, known as "Cedric", is only a basic prototype but could be developed into a new generation of digital devices that are smaller, faster and more efficient that today's silicon models. In another development, Nasa and agreed to share a $15m computer that reportedly uses quantum physics effects to boost its speed. The D-Wave machine had drawn scepticism from researchers in quantum computing until a scientific paper in April suggested it was indeed exploiting the strange behaviour of matter at quantum scales. However, the exact mechanism remains opaque. D-Wave's computer isn't the only thing tapping successfully into the quantum world; bird migration and the mechanics of smell were targets for research in the nascent field of quantum biology. Unlocking the past

In 2013, tests revealed that human remains estimated to be 4,000 years old and found at County Laois, Ireland, could represent the oldest bog body yet. Yet the chemistry which pickles bodies in bogs does not favour the preservation of DNA, which is unfortunate given the potential information these bodies could give up. This year saw the oldest human DNA sequence described as well as the most complete genome sequence from a Neanderthal. These studies revealed unexpected links between human groups, evidence for inbreeding and interbreeding, and the presence of a mystery early human species. But ancient DNA can also be put to use solving more recent puzzles about human migrations. Future fuels

The UK chancellor George Osborne committed his support to companies involved in shale gas "fracking", which has had a dramatic effect on the energy sector across the pond. So much so, that in 2013, the US began exporting shale gas for the first time. But fracking is but one of a variety of technologies designed to extract difficult-to- reachhydrocarbon deposits. But energy analysts will also have been closely monitoring the rapid transition to renewables in Germany. Despite huge opportunity, questions remain over who pays, the effects on tourism and the feed-in tariffs that could make renewable energy too expensive to store. Potential energy sources such as nuclear fusion remain some way off, though physicists in California made a breakthrough in their efforts to achieve self-sustaining laser fusion this year.

breakthrough in their efforts to achieve self-sustaining laser fusion this year. Discovery and de-extinction

Amid the sixth great mass extinction of life on Earth, researchers continue to find biological species previously unknown to science. This year's stand-out discovery was the olinguito (pictured above), a mammal living in the cloud forests of Colombia and Ecuador. Whilst no antidote to the biodiversity crisis, scientific advances might make the revival of extinct species possible. While many dream of seeing ancient giants such as the woolly mammoth walk the Earth again, more recently extinct species - such as the gastric brooding frog and the bucardo - are better candidates in the near term. Mind mapping

A US-led venture to map the wiring of the human brain released its first results in March. The Human Connectome Project should help determine how a person's brain structure affects their abilities and behaviour. The BBC's Pallab Ghosh got to test out the group's cutting edge imaging techniques on his own brain. The BBC also reported that efforts were underway to understand the workings of the teenage brain, to identify changes to the brain's wiring that controls impulsive and emotional behaviour as young people mature. One astonishing addition to the neurological bonanza was the news that scientists in Japan had been able to use MRI scans to "read" the images people saw in their dreams. New space pioneers

A nascent "" heated up in 2013, as India launched an unmanned probe towards Mars and China successfully landed its Jade Rabbit rover on the Moon - the first "soft" landing on the lunar surface in 37 years. Meanwhile, scientists at Imperial College London collaborated with the BBC to show how they would mount a manned voyage to Mars. Crewed missions to the Red Planet were all the rage in 2013: Space tourist Dennis Tito announced his search for a mature couple to undertake the journey, while the team behind the Mars One mission stated plainly that applicants for the venture would be on a one-way ticket.

10-01-2016 Dr.Tilak HR The Periodic table & the new discoveries

Science Page 11 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive The Periodic table & the new discoveries

The Periodic table • The periodic table is a representation of all chemical elements on earth based on their atomic numbers (increasing order) & properties • The present table, with 18 groups (columns) & 7 periods (rows), is a tabular presentation of 117 elements • The periodic table helps in understanding the properties of the existing elements & the similarities btw them. At the same time, it helps in predicting the properties of elements that are yet to be discovered The first table • Though many tables were proposed by scientists, it was in 1869 that Russian Dmitri Mendeleev managed to create the first exhaustive periodic table. He used atomic weights to arrange 60 elements in groups & periods ○ He also left space for elements like germanium, which were yet to be discovered. His table had 7 periods & 8 groups • In 1914, English physicist Henry Moseley found a link btw the X-ray wavelength of an element & its atomic number. He then went on to arrange the existing elements according to their atomic number & found properties of similar elements repeating themselves • Mosley's research too showed gaps in the table at atomic numbers 43 & 61 ; the elements were later discovered. Previous additions • In 2011, scientists added two new elements to the table. 114: Referred to as flerovium (Fl), this is a synthetic radio- active element. It was first discovered in 1998 in Russia. 116: Livermorium (Lv) too is not observed in nature and was discovered in the US in 2000 New discoveries

• The International Union of Pure & Applied Chemistry (IUPAC) — the global organisation that governs chemical nomenclature, terminology & measurement — confirmed in Dec 2015, that there was "sufficient evidence" to declare elements 113, 115, 117 & 118 as part of the periodic table • All the 4 elements are super-heavy, synthetic, man-made elements produced in the laboratory & have been given temporary names for now. They will be given permanent names by the countries that discovered them

Mythology, Religion & Science 07 November 2014 12:12 Sociology BA-2039,

Article 51A(h) places on all citizens the duty to develop a scientific temper

07-11-2014 • Mythology is magic realism in the sense that there is some realism and a lot of magic in the fabric of mythology, woven into legendary tales with supernatural objects and supernatural powers. • Myths also show the extremes of human behaviour, dilemmas, attitudes and paradoxes. • when the myths enter into people’s beliefs, mythology gets entangled with religion • PM Modi recently connected ancient mythology with contemporary science by claiming that present day inventions had already been materially invented in our ancient past • Science is based on information and accumulated knowledge. It requires that this information and knowledge be analysed methodically and logically. The reliability of the evidence, before it can be accepted as proof, has to be rigorously tested. This procedure obviously does not apply to imagination. • For the mythical creations of the past, there is no recorded evidence of such a development. It is true that both science and its discoveries and technology draw on creative inputs from imagination and invention. However, they are not based solely on imagination or they would remain dreams and not become reality. • Even the Pope, who is considered to be closer to God, has recently acknowledged evolution. • mythology and religion mix easily

11-11-2014 Science & Religion • Dan Brown -“Science and religion are partners. They are two different languages telling the same story... While science dwells on the answers, religion savours the questions.” • The question is how to become modern, scientific-minded people without losing on religion one’s own • The world is getting smaller everyday, there is enormous danger in believing that we are infallible. That our version of the truth is absolute and that everyone who does not think like we do is wrong and therefore our enemy Survival in an increasing shrinking world depends on the ability to ask difficult questions & engage in dialogue with people having ideas different to one’s own • Present era is exciting as first time in history the line between science & religion has started to blur • From infertility, earthquakes, to diseases even love, there was a God to explain everything, which later was filled by explanations by science. explanations by science • Ironically, we now turn to God for only for a handful of existential questions which science has never been able to answer like ‘Where did we come from? Why are we here? And what happens when we die?”

26-11-2014 India’s godman syndrome • There were great ascetics & kind & generous faith leaders who, at tremendous personal cost, often gave succour to the masses in times of great distress like Jesus, Muhammad, Vivekananda, Dayananda Saraswati • When these great souls depart, they leave behind followers who are human — all too human. As they lack the charisma of their gurus, they reduce the substance of their teachings to miracles and magic • Godmen do extraordinarily well in our country than in most others we know of • Hindu scriptures soften the mind & make it more prone to magic • The Vedas, for example, go on and on about how the gods must be pleased with libations and lavish praise, to win wars, beget sons, and acquire immeasurable wealth • what makes our godmen seem so powerful is that our politicians use them as baits to catch votes • Secularism truly means keeping religion out of politics. Likewise, democracy truly means keeping politics out of religion

22-12-2014 PM Modi said: “We can feel proud of what our country achieved in medical science at one point of time. We all read about Karna in Mahabharat. If we think a little more, we realise that [the] Mahabharat says Karna was not born from his mother’s womb. This means that genetic science was present at that time. That is why Karna could be born outside

Science Page 17 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

his mother’s womb. This means that genetic science was present at that time. That is why Karna could be born outside his mother’s womb… We worship Lord Ganesh. There must have been some plastic surgeon at that time who got an elephant’s head on the body of a human being & began the practice of plastic surgery” • We should avoid mixing myths & Indian knowledge systems

27-12-2014 Religion & Science • Religion is founded on FEAR, the fear of the unknown. But modern science has been able to explain almost all natural phenomena so that the purview of the unknown has shrunk considerably and the fear of nature is largely irrelevant. • There is no supernatural MIRACLE that has withstood the scrutiny of science. • We are born with a rational instinct, because a world-view that is consistent with natural laws gives us a distinct evolutionary advantage for survival. • We get our morality, not from religion, but from an innate sense of humanity and from being able to see the pain of a fellow creature — something other animals do not appear to be capable of. • Nobel-prize winning physicist to say “religion is an insult to human dignity. Without it you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.” • Religious belief is anachronistic in today’s science-driven world. • Einstein called belief in God a childish superstition. What he meant was that it is natural to give up this concept as we grow up and mature. • Philosopher Colin McGinn divides non-believers into atheists — those who could not care less whether others share their views or not — and anti-theists — those who actively campaign against religion because of the harm it does. But he foresees a society that is POST-THEISTIC, i.e., one in which religion is not an issue. • A society where people will look back and laugh at the primitive concept of God that we had till the 21st century. The way we look at primitive cave art today. • quote from Bertrand Russel’s essay, Why I Am Not A Christian, written almost 100 years ago: “We want to stand upon our own feet and look fair and square at the world, its good facts, its bad facts, its beauties, and its ugliness; see the world as it is and be not afraid of it. Conquer the world by intelligence and not merely by being slavishly subdued by the terror that comes from it. The whole conception of God is a conception derived from the ancient Oriental despotisms. It is a conception quite unworthy of free men ... A good world needs knowledge, kindliness, and courage; it does not need a regretful hankering after the past or a fettering of the free intelligence by the words uttered long ago by ignorant men.”

06-01-2015 • Science is grounded on the principle of reproducibility of results • The claims of advanced science & technology in the ancient world are based on some references in ancient scripts that may be wholly imaginary • Flying, for instance, has caught humankind’s imagination across cultures right from ancient times. Such references should be taken for the myths they are, not as scientific facts • Scientists have been able to create animal chimeras that have cells/organs of different species, much as what Greek mythology describes. Should the Greeks then be taken as pioneers in the science of chimera production? • Thanks to our understanding of genetics & the ability to fertilise eggs outside the body, producing designer babies is no longer in the realm of science fiction. Should the creators of the science fiction then be credited with devising the procedures?

11-01-2015 • Claims on 2,000-year-old texts providing answers to all present-day problems amounted to “freezing” ourselves in a historical past • Gandhiji, who revered the Bhagavad Gita , said that only 33 shlokas in it were relevant to him • Hence, we should pick what is relevant to us from our past & discard the rest

O’Keefe also showed that a specific rearrangement of place cells in different settings, called remapping, could be learned, the reason why we are able to place ourselves in an environment and navigate after some time. In effect, the place cells acted as a substrate for memory process, where memory of an environment was based on specific combination of place cells. The discovery of place cells and the demonstration that they represented a mental map, together with the proposal that the hippocampus containing the neural cells provides the inner map that store information of the environment were seminal. the entorhinal cortex, which lies on the dorsal side of the hippocampus, provided a major input to the hippocampus. A large part of the output from the entorhinal cortex projects to the dentate gurus in hippocampus, which in turn connect to the region in the hippocampus called CA3, and further to CA1 in the dorsal hippocampus.” The place cells are found in the CA1. entorhinal cortex contained cells that “shared characteristics” with the place cells in the hippocampus. The gird cells together with the place map provide the inner map. If the place cells provide the spatial map, the grid cells provide the navigation or path integration system. A single grid cell fires when an animal reaches particular locations in an arena. These locations are arranged in a hexagonal pattern. They also showed that the grid formation did not arise out of a simple transformation of sensory or motor signals, but out of complex network activity. The grid cells were part of a navigation or path integration system. The grid system provided a solution to measuring movement distances and added a metric to the spatial maps in the hippocampus The grid cells were “embedded in a network in the medial entorhinal cortex of head direction cells and border cells,

The grid cells were “embedded in a network in the medial entorhinal cortex of head direction cells and border cells, and in many cases, cells with a combined function.” The head-direction cells are like a compass that becomes active when the animal’s head turns in certain direction. The border cells, on the other hand, provide a reference to the wall or boundary of a room or environment. All the three cells — the grid cells, the head-direction cells and border cells — projected to the hippocampus place cells. The Mosers’ discovery of the gird cells, its spatial metric co-ordination system and the identification of the medial entorhinal cortex as a computational centre for spatial representation has been a breakthrough. Though the presence of place cells and grid cells were identified experimentally in rats, such a system is found in other animals too, including humans. The hippocampal-entorhinal structure is found in all mammals and a hippocampal-like structure is found in non-mammals with navigational capacity. This suggests that the functional and robust grid-place cells system in vertebrates must have been conserved. Results from functional imaging (fMRI) studies on human brains have provided support for the existence of place cells and grid cells in humans. Also, studies of patients undergoing neurosurgery have strengthened the evidence of place cells and grid cells in humans.

The discovery of place cells and grid cells and their role in spatial mapping and navigation have great implications in medicine. The reason why patients with Alzheimer’s disease often lose their way and cannot recognise the environment becomes clear as the hippocampus and entorhinal cortex, where the place cells and grid cells are located, are frequently affected at an early stage. Knowledge about the brain’s positioning system can help understanding of what causes loss of spatial awareness in stroke patients or those with devastating brain diseases like dementia, of which Alzheimer’s is the most common form and which affects 44 million people worldwide

3 Japanese scientists — Isamu Akasaki from Meijo University, Hiroshi Amano "for the invention of efficient blue light- emitting diodes which has enabled bright and energy-saving white light sources." The laureates' inventions revolutionized the field of illumination technology. White LED lamps can be created in two different ways. One way is to use blue light to excite a phosphor so that it shines in red and green. When all colours come together, white light is produced. The other way is to construct the lamp out of three LEDs, red, green and blue, and let the eye do the work of combining the three colours into white.

The principle for light-emitting diodes LED (upper left) and an example of a blue LED lamp. LED lamps are thus flexible light sources, already with several applications in the field of illumination — millions of different colours can be produced. Fluorescent light has mercury whereas LEDs doesn't. In future, it can be used to sterilise water as we know that UV light can kill bacteria and viruses. The LED lamp holds great promise: due to low power requirements it can be powered by cheap local solar power As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving earth's resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights Many home appliances are also equipped with LEDs. They shine their light on LCD-screens in television sets, computers and mobile phones, for which they also provide a lamp and a flash for the camera.

Background Living organisms were studied for the first time in the 17th century using an optical . The instrument opened a new window to studying living organisms non-invasively.

Despite the advantages, the optical microscope suffers from a major drawback — a physical restriction as to what size of structures is possible to resolve. Ernst Abbe in 1873 said that microscope resolution is limited by, among other things, the wavelength of the light (0.2 micrometres).

While Abbe’s microscope resolution limitation still hold true, the Laureates have successfully demonstrated ways of bypassing the limitation. The three have taken optical microscopy into a new dimension using fluorescent molecules. Two different principles have been able to do this and they developed independently of each other.

In stimulated emission depletion (STED), a light pulse excites all the fluorescent molecules, while another light pulse quenches fluorescence from all molecules except those in a nanometre-sized volume. Only this volume is then registered. By sweeping along the sample and continuously measuring light levels, it is possible to get a comprehensive image.

The smaller the volume allowed to fluoresce at a single moment, the higher the resolution of the final image. Hence, there is, in principle, no longer any limit to the resolution of optical microscopes.

Single- microscopy Unlike the STED microscopy, the single-molecule microscopy entails the superposition of several images.

• on how governments should regulate powerful companies that dominate markets • Mr. Tirole’s research showed that market regulations should be carefully adapted to the conditions of specific industries, rather than general regulations such as price caps which can do more harm than good. • Left unregulated, industries that are dominated by a few single firms can produce undesirable results, such as unnecessarily high prices or unproductive companies blocking new firms from entering the market. • his work has strong bearing on how governments deal with mergers or cartels. • deployed game theory and contract theory that aid regulation in situations of asymmetric information between regulators and the regulated & formalised several propositions about oligopolies and government contracting. - Before that simple methods were used to regulate monopolies like capping prices and prohibiting cooperation between competitors in the same market, - but Mr. Tirole proved that they were not always effective and in some instances caused more harm than good. (Price caps, for instance, can force dominant firms to cut costs, which is good but they could in the process lead to excessive profits for the firm, which is not so good.) • The case of a regulator not knowing a firm’s true marginal cost of production but needing to set prices. Or, a contractor wanting government to renegotiate terms halfway through by reporting a holdup due to cost escalation. In both these cases, Tirole showed that optimal government contracts might need to leave some fat on the bone for firms in order to incentivise them to comply. • Studied “two-sided” markets (direct relevance to E-Commerce)

• Studied “two-sided” markets (direct relevance to E-Commerce) - These markets bring together buyers and sellers on a platform they own, enable interaction between the two and charge both sides. (Eg. Amazon and or taxi aggregator firms like Ola Cabs or Uber) - He showed that the platforms often favour one side to attract the other (For instance, deep discounts on e- commerce platforms are used to drag in buyers and in the process bring in more vendors who pay the platform for its services). Regulators often do not understand these practices due to asymmetry of information. • Mr. Tirole’s work is also important in the context of today’s “Google-world” where the Internet giant strides like a colossus in the search domain and regulators are struggling to understand Google’s strategies and then figure out ways and means to regulate it. • Tirole’s “analysis of market power and regulation”- There are two central questions. First, how will firms behave when there are only a few of them in the market? What prices will they set, what range of goods will they offer, and what will be the quality level of these goods? Second, if competition among firms is insufficient to constrain prices, what policies should regulators use for the benefit of consumers and society at large? • also studied dynamic models of regulation, noting that regulators do not set firm incentives once and for all but typically revise them over time • Tirole has also studied regulatory issues in banking and finance, of special interest in view of the recent financial crisis. • He studied the implications of government bailouts in banking and considered how a government can restore a frozen asset market — the dilemma that was faced in the US market for mortgage-backed securities • He has devised models that are detailed enough to capture the relevant complexities, but simple enough to be accessible to a wide readership of economists

06-03-2014 Fostering Scientific Temper is Fundamental to Innovation and Progress National Science Day is celebrated in India on 28th February each year to mark the discovery of the ‘Raman Effect’ by Indian physicist Sir C.V. Raman on 28 February 1928. Sir C. V. Raman worked at Indian Association for the Cultivation of Science, Kolkata during 1907 to 1933 on various topics of Physics while making the famous discovery of the effect on scattering of light in 1928, which bears his name and got him the Nobel Prize in 1930.

In 1986, the National Council for Science and Technology Communication (NCSTC) had advised Government of India to designate 28 February as National Science Day. The event is now celebrated all over the country in schools, colleges, universities and other academic, scientific, technical, medical and research institutions. The theme of the year 2014 would be “Fostering Scientific Temper”. "Energy conservation" is also the theme of celebrating science Day in year 2014.

Scientific temper is a way of thinking and acting which uses a method. It may include observing physical reality, questioning, testing, hypothesizing, analysing, and communicating. Jawaharlal Nehru was one of the first persons to use the term scientific temper and advocate the promotion of scientific temper: "What is needed is the scientific approach, the adventurous and yet critical temper of science, the search for truth and new knowledge, the refusal to accept anything without testing and trial, the capacity to change previous conclusions in the face of new evidence, the reliance on observed fact and not on pre-conceived theory, the hard discipline of the mind—all this is necessary, not merely for the application of science but for life itself and the solution of its many problems", stated Pandit Jawaharlal Nehru in his book, The Discovery of India.

The genesis and development of the idea of scientific temper is connected to ideas expressed earlier by when he said, "freedom of thought will best be promoted by that gradual enlightenment of human understanding which follows the progress of science. Scientific temper describes an attitude which involves the application of logic. Discussion, argument and analysis are vital parts of scientific temper. Elements of fairness, equality and democracy are built into it.

India is one of the top-ranking countries in the field of basic research. Indian Science has come to be regarded as one of the most powerful instruments of growth and development, especially in the emerging scenario and competitive economy. In the wake of the recent developments and the new demands that are being placed on the S&T system, it is necessary for us to embark on some major science projects which have relevance to national needs and which will also be relevant for tomorrow's technology. The Department of Science & Technology plays a pivotal role in promotion of science & technology in the country. The department has wide ranging activities ranging from promoting high end basic research and development of cutting edge technologies on one hand to service the technological requirements of the common man through development of appropriate skills and technologies on the other.

Science, Technology and Innovation (STI) have emerged as the major drivers of development. As India aspires for faster, sustainable and inclusive growth, the Indian STI system, with the advantages of a large talent pool, can play a defining role in achieving these national goals. "To develop scientific temper" is one of the fundamental duties of Indian citizens, according to the Constitution of India.

India’s Scientific Policy Resolution (SPR) of 1958 had resolved to foster, promote and sustain the cultivation of science and scientific research in all its aspects. The Science and Technology Policy (STP) of 2003 called for integrating programmes of socio-economic sectors with the national R&D system to address national problems as well as creating a national innovation system. Scientific research utilizes money to generate knowledge and, by providing solutions, innovation converts knowledge into wealth and / or value. Innovation thus implies S&T based solutions that are successfully deployed in the economy or the society. It has assumed centre stage in the developmental goals of nations.

India has declared 2010-20 as the “Decade of Innovation”. The Government has stressed the need to enunciate a policy to synergize science, technology and innovation and has also established the National Innovation Council. The STI

Science Page 26 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

to synergize science, technology and innovation and has also established the National Innovation Council. The STI Policy 2013 in furtherance of these pronouncements, aims to bring fresh perspectives to bear on innovation in the Indian context. India’s global competitiveness will be determined by the extent to which the STI enterprise contributes social good and /or economic wealth. New structural mechanisms and models are needed to address the pressing challenges of energy and environment, food and nutrition, water and sanitation, habitat, affordable health care and skill building and unemployment.

Innovation for inclusive growth implies ensuring access, availability and affordability of solutions to as large a population as possible. The STI policy will drive both investment in science and investment of science-led technology and innovation in select areas of socio-economic importance. Emphasis will be to bridge the gaps between the STI system and the socio-economic sectors by developing a symbiotic relationship with economic and other policies.

The key elements of the STI policy are: • Promoting the spread of scientific temper amongst all sections of society. • Enhancing skill for applications of science among the young from all social strata. • Making careers in science, research and innovation attractive enough for talented and bright minds. • Establishing world class infrastructure for R&D for gaining global leadership in some select frontier areas of science. • Creating an environment for enhanced private Section Participation in R&D. • Creating a robust national innovation system, etc.

With the promotion of the scientific temper amongst all sections of society comes the need to create the right ambiance, structures to encourage research and innovation. India’s R&D investment is under 1% of the GDP. Increasing Gross Expenditure in Research and Development (GERD) to 2% of the GDP has been a national goal for some time. Achieving this in the next five years is realizable if the private sector raises its R&D investment. The gross budgetary support for the science and technology sector has significantly increased during the last decade.

Public understanding of science is an important dimension of introducing and reaching the benefits of modern science and technology to the people. Scientific temper needs to be promoted across all sections of the society systematically. Effective science communication methods, by using tools such as the National Knowledge Network, needs to be initiated. Public and political understanding of science should be based on evidence and debate with open mind. People and decision makers must be made aware of the implications of emerging technologies, including their ethical, social and economic dimensions

mathematician & astronomer in India — & possibly in the world • Varahamihira & Bhaskara were also leading mathematicians • The history of the term “sine” in trigonometry illustrates how we learn from each other & the interconnection of 3 mathematical traditions: Indian, Arabic & European ○ This trigonometric idea was well developed by Aryabhata, who called it jya-ardha, & sometimes shortened it to jya ○ Arab mathematicians, using Aryabhata’s idea, called it “jiba”, which is phonetically close ○ later generation of Arab mathematicians used the term jaib, which means a bay or a cove ○ Then, in 1150, when Italian mathematicians translated the word into Latin,“sinus”, which means a bay or a cove ○ And it is from this — the Latin sinus — that the modern trigonometric term “sine” is derived

14-01-2015 • Non rusting iron was first made in India • the traditional pharmacopoeia in Ayurveda is rich in insights on natural products with curative properties

• what is needed is a scientific assessment & appreciation of our heritage, rather than a jingoistic recollection of some mythical golden age

18-03-2015 Contributions of Brahmagupta • 6th & 7th centuries AD was the era of the mathematician Brahmagupta • He was the first to clearly define zero & to explore all its properties • He also invented negative numbers as a concept ○ Rather than treat numbers simply as abstract concepts, however, Brahmagupta was also able to give negative numbers practical significance by calling them “debts” — something that must have instantly resonated with lenders & borrowers • Brahmagupta was the real genius behind “Arabic numerals” now called "Hindu Arabic numerals" Pythagoras theorem & Baudhayana • the “Pythagorean” theorem was conceived 200 years before Pythagoras, in 8th century BC India, when the same result was pointed out by Baudhayana in his Sulba Sutra • Baudhayana showed that the square formed by the “diagonal” of a triangle has the combined area of the squares formed by the length & breadth of the triangle — the geometric analogue of the Pythagoras theorem

06-05-2015 • Invention of Decimal System ○ Hindu mathematicians used a system based on 10. ○ The Hindus had symbols for each number from one to nine. ○ They had a name for each power of 10 ○ They invented the symbol shunya (meaning empty), which we call zero • Atomic Theory ○ Sage Kanad, 600 BC, is recognized as the founder of atomic theory, & classified all the objects of creation into nine elements (earth, water, light or fire, wind, ether, time, space, mind and soul) ○ He stated that every object in creation is made of atoms that in turn connect with each other to form molecules • First & Longest Poetry of the World • The Ramayana is the first poetry of the world. It is a glorious Sanskrit epic written by the Divine Sage Valmiki. It has 24,000 Samkskrit verses. It was later translated by Kamban & Tulsi Das • The Mahabarata is the longest poetry ever written. Its 100,000 verses encompass all facets of Dharma or human way of life. It narrates the story about the great Mahabarata war btw the noble Pandavas & their evil cousins the Kauravas • Ancient root of Navigation ○ The art of Navigation was born in the river Sindhu 6000 years ago. The very word Navigation is derived from the Sanskrit word 'Navgatih'.

PM Modi on science

04-01-2015 • India Inc. needed to fund more research through various initiatives including Corporate Social Responsibility • He also invited the Indian scientific diaspora to contribute by guiding & teaching the doctorate scholars in the country • Since independence, scientists have made outstanding institutions with modest resources. They have alleviated some of the most acute challenges of human development, have increased food production, have secured borders & have increased the pace of industrial progress • Modi has placed science & technology at the forefront of the country’s diplomatic engagement • Regarding ease of doing research in India, the funding proposal must not take too long • He said the country needed a clear regulatory policy for research & technology in biotechnology, nanotechnology & clinical research • He invoked the Vedas to explain the purpose of science. Science is driven by the compassion of heart to make human life better

05-01-2016 Dr.Tilak HR PM Modi on Indian science • Greater scientific collaboration btw central & state institutions & agencies is necessary as part of cooperative federalism • PM Modi called on Indian scientists to keep the Economy, Environment, Energy, Empathy & Equity (5Es) at the heart

Science Page 31 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• PM Modi called on Indian scientists to keep the Economy, Environment, Energy, Empathy & Equity (5Es) at the heart of their endeavors in the interest of impactful science ○ Scientists need to find cost effective & efficient solutions, ensure our carbon footprint is the lightest, focus on energy since prosperity depends on green energy, display empathy by ensuring efforts are in tune with our culture, circumstances & social challenges & create equity where science advances inclusive development & improves the welfare of the weakest • If we wish to restore the harmony btw human & nature we must also harness the full potential of traditional knowledge ○ Societies across the world have developed this enormous wealth through gathered over the ages ○ They hold the secrets to economic, efficient, &, environment friendly solutions to many of our problems. But today they are at risk of extinction in our globalised world • In the area of health, modern medicines have transformed healthcare. But we must also use scientific techniques & methods to delve deeper into traditional medicines & practices like yoga for more holistic lifestyle & change our paradigm from treatment to wellness • Humanism defined Einstien's thought behind his discoveries: Concern for man himself & his fate must always form the chief interest of all technical endeavours (Humanism) • Good governance is not just about policy & decision making, transparency & accountability. It is also about integrating science & technology into the choices we make & the strategies we pursue • Need to make it easier to do science & research in India, improve science administration, & expand the supply & improve the quality of science education & research in India

Indian Science Congress

• The science congress was started in 1914 • Indian Science Congress Association, based in Kolkata conducts the event

11-01-2015 102nd Indian Science Congress in • The idea of promoting science through the congress began in earnest after Independence, continuing till 1967, but the efforts have since lost focus. After 1967, politics became uncertain & universities became the centre for political activities • This year’s Congress included a section on “Ancient sciences through Sanskrit” • National scientific meeting is customarily inaugurated by a Prime Minister in India while in majority of other countries its by an eminent scientist • The quality of papers being presented have generally been poor

22-03-2014 Generating funds to carry out independent research is a cause of great concern.

03-04-2014 What ails Indian science? Indian science’s bureaucratic mentality values administrative power over achievements “Getting funding [for research] is easy in India,” said Dr. Mathai Joseph “because there is no competition here. Money is not scarce [though R&D spending is less than 1 per cent of GDP]. But money comes with the same bureaucratic restrictions that apply to all government expenditure.” Dr. Joseph is a computer scientist and a consultant, and was earlier a senior research scientist at TIFR, Mumbai. For instance, while research students get no funding support to travel abroad to participate in conferences, scientists are constrained by “limited foreign travel.” These restrictions on foreign travel prevent students and scientists from gaining in terms of networking, exchanging ideas and being exposed to the kind of work being done by their peers in other countries. “Science does not happen like that — by not allowing them to travel abroad,” he said.

The big mistake But the systematic undermining of scientific enterprise started way back in the mid 1950s. According to an opinion piece published today (April 3) in Nature, (Dr. Joseph is the first author), the Department of Atomic Energy, which was created as a different model, had Homi Bhabha, the head of DAE as a “secretary to the government.” The mistake was

Science Page 32 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

created as a different model, had Homi Bhabha, the head of DAE as a “secretary to the government.” The mistake was repeated when the DAE model was replicated in other institutions — space and biotechnology, to name a few. “The fact that scientific departments are modelled on the rest of the bureaucracy has turned out to be a big mistake,” Dr. Joseph said. “That’s because bureaucracy is not designed to encourage innovation. DAE and the are the only institutions that undertake developments in-house. Others like the DBT [Department of Biotechnology] do not.” Contrast this with the system followed in the developed countries. For instance, in the case of the U.S., the National Institutes of Health (NIH) and the National Science Foundation (NSF) are outside the government bureaucracy. By being a part of the bureaucracy, even those scientists in India who do remarkable research cannot be rewarded with promotion or pay hike. “If you reward scientific achievement rather than years of service, scientists would be motivated to take up novel scientific challenges,” he noted. Regrettably, the malaise of promotion based on years of service, and not by achievement has spread to institutions at the national level too. “Indian science has for too long been hamstrung by bureaucratic mentality that values administrative power over scientific achievements,” the paper notes. It is, however, pertinent to note that the department of space stands out from the rest. Younger people have been put in charge of important programmes, and they have succeeded. “This system is quite old in the department of space,” Dr. Joseph said.

The golden era These essentially explain why prior to the 1950s important contributions from people like Jagadish Chandra Bose, and Srinivasa Ramanujan came from within the country. The pioneering work by these people came before “the machinery of government took over and mismanaged research.” Another problem is the lack of lateral movement from one institution to another. While collaborating with scientists from other institutions would go a long way in putting to test the usefulness of one’s expertise without actually moving to another institution, one ends up gaining more by moving out. “Vitality grows from being challenged in scientific terms [when one moves from one institution to another],” Dr. Joseph said.

Collaboration Incidentally, even collaborating with scientists from other institutions is rarely seen in India. Worse, even the funding agencies do not insist on this. Funding is rather provided for collaboration within the institution than across institutions. This is true even in the case of the Nano mission launched in 2007. According to the authors, the Nano mission has funded 150 individual projects, 11 centres of excellence and six industry-linked projects. “But [the mission] has required no collaboration between institutions,” the paper notes. “There are very few national frameworks for collaboration,” he said, “working towards a common goal is missing.” Collaboration becomes all the more important as the size of the groups in any area is small in India. It is true that there is an inherent resistance to collaboration across institutions in other countries as well. “But programmes like ESPRIT [European Strategic Programme on Research in Information Technology] insist on collaboration across institutions and countries for funding,” he said. According to the paper, one of the four changes that need to be urgently initiated to reinvigorate research is to decouple funding and government control. “Indian science needs public funding, but not government control,” the paper notes. There are numerous examples in other countries and in Europe where such a system has been operating successfully. The tenure of heads of institutions should also be limited and they should be encouraged to return to active research. “The rotation should be every five years. It’s very hard to do research when you head an institution,” he said, “you can’t do research full time.”

30-04-2014 • Former PM Jawaharlal Nehru coined the phrase ‘scientific temper’ & described dams & power plants as "modern temples" • Currently 0.8% of GDP is being spent on Science & Technology

27-12-2014 Scientific grants • Generally, grants are given by subject committees, making them highly discipline-oriented • However, there are means of getting interdisciplinary grants through the new Science & Engineering Research Board that is created recently

that is created recently Embracing an interdisciplinary approach • today most subjects are themselves becoming interdisciplinary • The frontiers of biology now deal with physics & computational science • Some of the greatest works in medical science today borrow from chemical engineering & nanotechnology • If India has to make it to the cutting edge of science, it will have to embrace an interdisciplinary approach Funding for Science • Science funding has to be around 2% of the GDP in order to be a world leader in science • Space & atomic energy are technologies not science (since these agencies are involved in developing technology such as reactors, rockets & so on). So they should not be included in science funding • Funding should be focussed more on fundamental science (like biology, chemistry, physics etc.) • Right now, our total science funding, including space & atomic energy, is still < 1% of GDP • But for that, the industry also has to contribute & directly support research • In US & in South Korea, nearly 45-50% of research is industry funded. In India, their contribution towards scientific activity is < 10% • Industry should support both long-term & short-term research. They will after all benefit from it in the future

06-01-2015 Digital connectivity, a basic right- PM Modi • Nurturing the scientific temper would result in accelerated development • PM has elevated to the level of a basic right, on par with the right to education • Other ideas include channelling CSR funds to research & recognition of the importance of innovation: “science is universal, but technology can be local” • The PM has also proposed a regulatory framework for biotechnology, nanotechnology, agricultural & clinical research • he has also talked of the need for multidisciplinary research work, which promises high return on investment • PM stressed the need for R&D, which can be rapidly encashed for development & the need for fundamental research, which is a long-term investment • academic autonomy is necessary from which most great scientific breakthroughs stem • He called to make science & technology as theme of Republic day • it is as important to focus on basic fundamental research as on research & development & innovation • If we incorporate traditional & local knowledge, systems & technologies, we may develop more appropriate, effective, affordable & sustainable solutions • ease of doing research & development in India is important just like ease of doing business in India • Funding proposals must not take too long to clear; meeting application requirements should not become more complex than research • the approval process should not become a deterrent for international conferences • our scientific departments must have flexibility on funding decisions based on the uncertainties inherent in research activities • We want our scientists & researchers to explore the mysteries of science, not of govt procedures • not just scientific depts, but every other dept in the govt should see how to apply science & technology & promote research to improve their work ○ Each should have an officer focusing on science & technology relating to its area of work & allocate a percentage of its budget for such activities • Investments in science & technology activities should also become part of the expenditure on CSR — to be funded directly or through an autonomous fund • We also need to foster a strong culture of collaboration between institutions & across disciplines to take advantage of developments, innovation & expertise in diverse areas • We have to place the university system at the cutting edge of research & development activities in the country • Our investments in science & technology are far too concentrated in the agencies of the Central govt & must become more broadbased • Our universities must be freed from the clutches of excessive regulation & cumbersome procedures ○ They must have a higher degree of academic freedom & autonomy & there should be as much emphasis on research as on teaching ○ In turn, universities must also subscribe to the highest academic & research standards & accountability including thorough peer review

Science Page 34 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

thorough peer review • India’s pharmaceutical industry has carved out a place for itself in the world because it invests significantly in research ○ Our long-term global competitiveness will depend not on replicating what others have done but on a process of sustained development & innovation • There is a growing trend of international collaboration in R&D, not just among business enterprises, but equally among researchers & scholars at universities & laboratories ○ For this, Modi has placed science & technology at the forefront of our diplomatic engagement • India's future will be secure & global leadership possible if we prepare the next generation of world-class scientists, technologists & innovators along with skill development of youth • School education in science & mathematics should become more creative & stimulating • use the internet to bring the best of our scientists in direct contact with our children & our youth • Digital connectivity should become as much a basic right as access to school • We in India are the inheritors of a thriving tradition of Indian science & technology since ancient times • Mathematics & medicine, metallurgy & mining, calculus & textiles, architecture & astronomy — the contribution made by Indian civilisation to human knowledge & advancement has been rich & varied

• At the dawn of freedom, PM Jawaharlal Nehru placed science & technology at the heart of national development • Our scientists launched pioneering research & built outstanding institutions with modest resources that continue to serve us well • Since then, our scientists have placed us at the forefront of the world in many areas • Our scientists put Mangalyaan in the Mars orbit in the first attempt • their accurate prediction of Cyclone Hudhud saved thousands of lives

06-01-2015 • A study reveals that the percentage of the country’s GDP spent on R&D had stagnated around 1% for over two decades • There should be a massive increase in quality & quantity in Science & Technology education if the country’s aspiration of becoming a leading global force in science was to be attained ○ btw 2004 & 2006, India had produced only one research scientist for every 7,100 people as against the average of one for 1,080 in China, one for 240 in South Korea & one for 163 in Sweden ○ Need for making the pursuit of scientific research an attractive career option for the youth

15-01-2015 • Article 51A(h) of the constitution [42nd Amendment, 1976]: It shall be the duty of every citizen of Indian “to develop the scientific temper, humanism & the spirit of enquiry & reform” • India has not produced any Nobel Prize winner in science in the last 85 years – largely coz of the lack of a scientific environment in the country, of which scientific temper would be an important component

14-02-2015 • ‘Grand Challenge Programme’ on vaccines set up by the Dept of Biotechnology • biotechnology push in India started in the mid-1980s, & that has gained in strength over time Pharma R&D • For a robust research ecosystem, adequate funding & good pipelines from ensuring minimum friction in the development of drug candidates to its release into market • Pharma companies are uncertain about Intellectual Property Rights on essential drugs, unsure about whether they can recover the high costs incurred • Policymakers in India will need to strike the right balance btw public funding, & the role & return on private investment on drug development ○ the unwritten compact in developed countries on drug development is that a thick layer of public funds pay for the basic research up to & including drug candidate discovery ○ It is over & above this that private pharmaceuticals come in, patent drugs & develop them Indian funding on basic research & drug discovery remains minuscule in comparison, with the entire Dept of Biotechnology budget (< Rs.1,500 crore in 2014-15) ○ both the quality & quantity of public spending has to dramatically improve if we want more drug candidates against TB, malaria, dengue, cholera & other diseases

Science Page 35 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

against TB, malaria, dengue, cholera & other diseases ○ One way to increase funding is to redirect extensive funds that go towards large health-care subsidies, so that future drugs can be better & cheaper ○ India can re-examine how clinical trials are governed (while we want ethical & safe practices in clinical testing, American or European regulations have accumulated some extra bureaucracy & regulations along the way) ○ India can also set new standards on transparency so that new research is easy to discover, verify & build on

26-02-2015 • Indian science allocation has been falling. It is 0.8% of GDP, while in the US it is 2.8% of GDP. In China it is 1.8% • Indian Science, Technology, Agriculture & Medicine (STEAM) over the last two years or so have suffered an across- the-board cut of over 30% of the allotted budget which was imposed by previous govt & continued by the present • Unlike in Europe, Japan or the US, private industries here do not have foundations that support research by others; they at best support in-house research & development • Thus, STEAM have to depend entirely on the central & state govts for support • Domain expertise, independence in decision making & autonomy made the original 5 IITs famous • Professor Amartya Sen said recently that academic governance in India remains deeply vulnerable to the opinions of the ruling govt

28-03-2015 • 3 of the leading scientific agencies in the country are Council of Scientific & Industrial Research (CSIR), Indian Council of Medical Research (ICMR), & Defence Research & Development Organisation (DRDO) • Take example of Israel where high quality & worldwide impact of basic scientific research is done • There must be a definitive but liberal policy on providing venture capital for start-ups in new areas of technology ○ This must be through govt-funded agencies such as the Industrial Credit & Investment Corporation of India & the Industrial Development Bank of India • 2nd or 3rd-rate research that is repetitive or a trivial follow-up of leads provided elsewhere in the world must be discouraged ○ This will ensure that the quality-to-quantity ratio in the country in respect of basic research goes up

15-05-2015 What ails science in India? • the govt’s shocking decision to dissolve the scientific advisory council to the Prime Minister, thereby cutting a crucial link that has served science & the scientific community well ○ Another jolt has been the cut in research budget, which has been static for about a decade at a paltry 0.9% of the GDP (China’s is almost 2%) • India has only 200,000 full time researchers — 4 researchers per 10,000 labour force. While China has 18 & Brazil 7 • The number of research papers published by researchers based in the country has nearly quadrupled since 2000 but it is way too low compared with China • Besides the 40 CSIR laboratories, a few premier research institutions like the IISc, Bengaluru, TIFR, Mumbai, 16 IITs & 5 Indian Institute of Science Education & Research (IISER), there are over 600 universities in the country ○ But hardly any of the international-level research is done in the universities • Facilities & teaching at the universities that serve > 29 million students are alarming • Need for complete overhaul of UGC ○ Archaic ordinances & rules set by UGC have stifled the spirit of academic excellence & hampered institutions’ flexibility • Though India produces 9,000 PhD graduates a year in science & technology, the number pales in comparison with the it’s population. The US produces 4 times more number of PhDs despite having 1/4th of India’s population ○ The variation in quality of Indian PhD graduates & faculty members is a prime concern ○ Quality-control mechanisms must be established for the national accreditation & assessment of Indian PhDs & to improve research & educational training • Unlike in the West where talent is spotted at the graduate level & nurtured, researchers in India are mentored way too late

10-01-2016 Dr.Tilak HR What ails Indian science • Nobel laureate Venkatraman Ramakrishnan's described of the Indian Science Congress as a circus

Science Page 36 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• Nobel laureate Venkatraman Ramakrishnan's described of the Indian Science Congress as a circus ○ 59% of secondary schools in India don't have an integrated science laboratory although science is compulsory till class 10. So, a vast majority of students 'study' science without ever seeing any experiment, let alone doing it • The crisis in science is coz it is not attracting the best minds ○ Science education has moved from being a curiosity-driven exploration to a mark-scoring exercise to get admission in elite institutions & bag a fat corporate salary ○ In the process, academia has also lost high quality teachers who shape young minds • There are serious problems facing Indian science, ranging from resource crunch to policy confusion • The current attempts to turn mythology into science make the future look even bleaker • Building a knowledge-based society demands significant increase in investment for S&T at several levels including education as well as research leading to outcomes in pure & applied areas ○ India has just 4 scientific researchers for every 10,000 people in the workforce, much lower than not just advanced countries like the US or UK but even China & Brazil ○ Scientific papers published by Indians numbered about 90,000 in 2013 compared to 4,50,000 by Americans & 3,25,000 by Chinese ○ Citations too were below the world average. Indians filed just 17 patents per million population compared to 541 in China & 4,451 in South Korea ○ It is a combined result of defective grounding at the school/college level & limited resources for research • The goal of spending at least 2% of GDP on scientific research - outlined in the govt's science policy of 2003 - has not been achieved. Even industry funding, which was declared as the magic wand for finances, hasn't delivered ○ As per latest available figures, India is spending < 1% on research & development compared to 1.9% in China & 2.75% in US • Rather than quantity its the quality of science that is important. It is also not showing any improvement. India still contributes < 1% of the world's top 1% of research • We need many good institutions doing outstanding work, so that we can accommodate capable young scientists • Some scientists feel however that given the low input, & that the best minds have left India for greener pastures, Indian science has done "outstandingly well" • In today's environment of research in project mode with well-defined objectives, milestones & deliverables, curiosity-driven research is a casualty • Research objectives too are increasingly disconnected from society ○ For eg. In agriculture, there is an obsession with increasing yield while ignoring the consequences of intensive agriculture in the 5 major grain producing states has led to a sustainability crisis - ground water depletion, waterlogging, chemical over-kill ○ Our research goals continue to be better yielding varieties rather than sustainable productivity

12-01-2016 • A framework for audit of scientific depts as suggested by PM Modi is the first step. We need complete overhaul of science education to create an environment that encourages research & innovation • Filmmaker Shyam Benegal advocated a 24-hr TV channel dedicated to science to promote scientific temper in India •

Jan-2013 Science, Technology & Innovation Policy 2013 It focuses on faster sustainable & inclusive development • The term “innovation” which was not present in previous policies drafted by the Centre. • The policy also takes into account the affordability and accessibility of innovation… bringing in more focused, people-centric processes. • The new policy stresses on promoting scientific thinking across all sections of society and making careers in science, research and innovation more attractive. It also aims to establish world-class science and technology infrastructure to position India among global science leaders by 2020. • The policy calls for attracting private investment in research and development as well as increasing investment in the sector. It also aims at serving the nation’s agenda in agriculture, manufacturing and services sectors

INSPIRE Programme Innovation in Science Pursuit for Inspired Research (INSPIRE) • an innovative programme sponsored and managed by the Department of Science & Technology for attraction of talent to Science. • The basic objective of INSPIRE is to communicate to the youth of the country the excitements of creative pursuit of science, attract talent to the study of science at an early age and thus build the required critical human resource pool for strengthening and expanding the Science & Technology system and R & D base. It is a programme with long term foresight. • A striking feature of the programme is that it does not believe in conducting competitive exams for identification of talent at any level. It believes in and relies on the efficacy of the existing educational structure for identification of talent. • The strength of the innovation infrastructure of a nation has enormous significance in the competition among emerging knowledge economies. The realization of Vision 2020 calls for action and a well designed innovation infrastructure INSPIRE has 3 components: • Scheme for Early Attraction of Talent (SEATS)- 10 to 15 yrs ○ INSPIRE Award (for 10-15 age group): Rs.5,000/- to one million young learners. ○ INSPIRE Internship (for 16-17 age group): Annual Summer/Winter Camps for about 50,000 youth at more than 100 locations, for toppers in Class X board examinations for exposure with global leaders in Science • Scholarship for Higher Education (SHE) ○ INSPIRE Scholarship (for 17-22 age group): The scheme offers 10,000 scholarships every year @ Rs 0.80 lakh per year to talented youth, for undertaking Bachelor and Masters level education in Natural and Basic sciences • Assured Opportunity for Research Careers (AORC) ○ INSPIRE Fellowship (for 22-27 age group): for doctoral research, in both Basic and Applied sciences (including engineering and medicine). ○ INSPIRE Faculty Scheme (for 27-32 age group): assured career opportunity for post-doctoral researchers

Shanti Swarup Bhatnagar Award • Shanti Swaroop Bhatnagar awards, the most prestigious national recognition for scientists < 45 yrs of age • It is an annual award given by CSIR which carries a cash prize of Rs 5 lakh, a citation & a plaque

Funding R&D

12-03-2015 • Private industry & the NRI community should think of contributing to India’s efforts in R&D in STEAM, humanity & social sciences • Elsewhere in the world, private industry & individual business magnates have set up their own R&D Foundations which offer competitive grants

Science Page 38 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

which offer competitive grants ○ Indian business tycoons need to go beyond “corporate social responsibility” & set up R&D funds ○ bodies such as FICCI, CII, NASSCOM & ASSOCHAM can initiate similar grants ○ such funds be managed in collaboration with science academies & similar scholarly groups with domain expertise to disburse them • The Non-Resident Indians can start a not-for-profit R&D fund to help India’s STEAM? (like in Israel) ○ Such a fund will go a long way to accelerate the growth & improvement in India’s STEAM & education

30-08-2015 • Centre to set up science centres & zonal systems to support research in all States

28-10-2015 ‘Dehradun Declaration’ to develop a business-like revenue model for R&D • The decision was part of ‘Chintan Shivir’ held at Dehradun in June 2015 & ended with all CSIR labs resolving to turn research projects into ‘for-profit’ ventures over the next 2 yrs • Under the Dehradun Declaration, research institutions have been asked to raise part of their money for research through external funded projects & grants ○ As part of the ‘Dehradun Declaration,’ all laboratories signed up to develop a business-like revenue model with a clear cost-benefit analysis ○ Moving forward, research institutions will have to submit their short-term & long-term projects (btw 1 & 3 yrs) to the govt • Cash-strapped, the Ministry of Science & Technology has mandated organisations (CSIR etc.) involved in scientific research & development (R&D) to generate half of its funds; send in monthly updates & ensure that research stays in sync with the Central govt’s ‘social & economic objectives’ • This will not include funding for the Bhabha Atomic Research Centre (BARC) & Tata Institute of Fundamental Research (TIFR) — both under the Dept of Atomic Energy (DAE) Analysis • The Dehradun Declaration is a vision document with a clear focus on deliverables having relevance to the common man on fast track • The majority of CSIR labs have all the competence & expertise to generate external cash flows • All good fundamental science research leads to applied research & CSIR is a unique agency which has competence to perform translational research in our country Critics • While senior & established researchers can manage to secure grants, young researchers can have a tough time which might affect their quality of research • Scientists are now required to show how their research contributes to 'society outreach' • In addition to funding for research, the number of fellowships too is being cut down • They are required to submit reports every month on the progress of their work & state what part of their work gives back to society • Science & technology is not the only Ministry to see budget cuts. In March 2015, HIV/AIDS-related research in India became a casualty of similar budget cuts Govt's view • There is no harm in relying on industry to scale up or take forward the research projects under way • If the labs make more money, the research will be better utilised • Gvot claims that it is not giving any targets to research institutions but just want them to be better coordinated & have more accountability

Uchatar Avishkar Yojna

28-10-2015 • Under the ‘Uchatar Avishkar Yojna’ institutions of excellence will have industry partners in their research projects • Ministry for Human Resource & Development (MHRD) has earmarked Rs.250 crore per annum for fostering “very high quality” research in institutions of excellence • The scheme will initially be limited to the IITs • IITs can start applying for govt money for funding if their research has 'clearly defined outcome' & 25% of the

Science Page 39 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• IITs can start applying for govt money for funding if their research has 'clearly defined outcome' & 25% of the expenses have to be borne by an industry partner • The proposals will have to specify the time-frame, the outcome & the benefits that the industry stands to gain from the research to be eligible for the funds Govt's view • A large part of the mandate for the IITs was to train very high quality manpower & produce outcomes that are relevant for the design & manufacturing industry • Govt wants the IITs to help in the Make in India campaign, by investing in research & link innovation to the industry to make the latter competitive in the global markets • Govt is looking at Rs.1,500 crore funding over the next 3 yrs to give manufacturing a boost Concerns • The proposal has been received with scepticism in the academic & research circles, given the implications of allowing private players to collaborate with institutions which have been set up with public money ○ There was a need to guard against privatisation of public institutions • This proposal will shift the focus from fundamental research to applied research; thereby not allowing the scope of research to expand ○ To be competitive, equal weightage has to be given to fundamental research, which forms the basis of applied research • With the private companies partnering in research, there will be the issues of intellectual property rights

NRN Murthy & CNR Rao's viewpoints

11-09-2015 C N R Rao: All funding comes from the govt, industry has contributed little • NR Narayana Murthy had questioned the contribution of institutions such as IITs & IISc & had said that there has not been a single invention from India which has gone on to become a household name globally in the last 60 years • NRN Murthy was right, but so is Rao • Several of the truly groundbreaking inventions from the last half-century or so, such as the internet, cellphone or the GPS, originated from research subsidised by the US military ○ many of these technological innovations is funded by private partners • Globally, around 40-50% of the scientific research in institutions are supported by industry & the remaining 50% is supported by the govt. In India, however, it is almost all by the govt (Industry contribution is negligible) ○ The govt has not increased its spending on education above 2% of the GDP; for science, it is < 1% of the GDP. It is high time they are 6% & 2% of the GDP, respectively ○ Moreover, for the investments made, India has done pretty well ○ While more investment is needed to create better facilities, it is equally important to work harder under the existing conditions ○ We have to make more effort on pressing problems of society like energy, water, environment & so on . To take up such major challenges, we would require a different type of infrastructure & funding ○ As Rao noted, Indian billionaires have not, separately or together, founded institutions like MIT or Stanford — both of which have trained & nurtured the best minds to enable scientific advancement ○ Reports suggest that philanthropy levels in India remain low by global standards ○ While IISc & some IITs have produced leaders in academics, industry & govt, it is also true that it has not been possible to work at the same level as Harvard, MIT or Berkeley for various reasons . The primary responsibility of IISc, IITs & such institutions is the education of UGs & PGs in science & engineering. In this respect, they have done as good a job as one can . These graduates have performed well in India & in leading institutions elsewhere

27-09-2015 • The Indian education system encourages students to be risk-averse & favour career-specific skills over creativity • Murthy has cited the example of the Massachusetts Institute of Technology (MIT), whose labs have helped to define the modern world with numerous inventions, while its Indian peers like the IITs have failed to contribute even a single device or technology which is depended upon worldwide • Significantly, he was not only speaking the language of growth, brands & business value, but was also referring to ideas, technologies, inventions & innovations which define quality of life & have powered the rise of civilisation

Satyendranath Bose

Satyendranath Bose (1894-1974) was born in Calcutta in 1894, is among the great Indian physicists who made a fundamental contribution to the advance of science in the twentieth century. An outstanding student throughout, Bose started his career in 1916 as a lecturer in physics in Calcutta University; five years later he joined Dacca University. Here in 1924, in a brilliant flash of insight, Bose gave a new derivation of Planck’s law, treating radiation as a gas of photons and employing new statistical methods of counting of states. He wrote a short paper on the subject and sent it to Einstein who immediately recognised its great significance, translated it in German and forwarded it for publication.

Science Page 42 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

to Einstein who immediately recognised its great significance, translated it in German and forwarded it for publication. Einstein then applied the same method to a gas of molecules. The key new conceptual ingredient in Bose’s work was that the particles were regarded as indistinguishable, a radical departure from the assumption that underlies the classical MaxwellBoltzmann statistics. It was soon realised that the new Bose-Einstein statistics was applicable to particles with integers spins, and a new quantum statistics (Fermi-Dirac statistics) was needed for particles with half integers spins satisfying Pauli’s exclusion principle. Particles with integers spins are now known as in honour of Bose. An important consequence of Bose-Einstein statistics is that a gas of molecules below a certain temperature will undergo a to a state where a large fraction of atoms populate the same lowest energy state. Some seventy years were to pass before the pioneering ideas of Bose, developed further by Einstein, were dramatically confirmed in the observation of a new in a dilute gas of ultra cold alkali atoms - the Bose-Eintein condensate

JC Bose

Acharya Sir Jagadish Chandra Bose [1858 – 1937] was a Bengali polymath, physicist, biologist, botanist, archaeologist, as well as an early writer of science fiction. He pioneered the investigation of radio and microwave optics, made very significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent. He is considered the father of Bengali science fiction. He also invented the crescograph Radio research James Maxwell mathematically predicted the existence of electromagnetic waves of diverse wavelengths. Heinrich Hertz showed experimentally the existence of electromagnetic waves in free space. Bose reduced the waves to the millimetre level (about 5 mm wavelength). He realised the disadvantages of long waves for studying their light-like properties During public demonstration at Town Hall of Kolkata, Bose ignited gunpowder and rang a bell at a distance using millimetre range wavelength microwaves. Therefore, messages can be transmitted by means of it without the mediation of wires. Bose's first scientific paper was "On polarisation of electric rays by double-refracting crystals". At that time, the word 'coherer', was used for Hertzian wave receivers or detectors. Bose developed "iron-mercury-iron coherer with telephone detector".

Bose's demonstration of remote wireless signalling has priority over Marconi. Bose was a pioneer in microwave optics technology. He was the first to show that semiconductor rectifiers could detect radio waves. Bose’s galena receiver was amongst the earliest examples of a lead sulphide photo conducting device Plant research His major contribution in the field of was the demonstration of the electrical nature of the conduction of various stimuli (e.g., wounds, chemical agents) in plants, which were earlier thought to be of a chemical nature. He invented a machine called the crescograph to study all this.

These claims were later proven experimentally. He was also the first to study the action of microwaves in plant tissues and corresponding changes in the cell membrane potential. He researched the mechanism of the seasonal effect on plants, the effect of chemical inhibitors on plant stimuli and the effect of temperature. From the analysis of the variation of the cell membrane potential of plants under different circumstances, he hypothesised that plants can "feel pain, understand affection etc." His books include Response in the Living and Non-Living and The Nervous Mechanism of Plants Study of metal fatigue and cell response Bose performed a comparative study of the fatigue response of various metals and organic tissue in plants. He subjected metals to a combination of mechanical, thermal, chemical, and electrical stimuli and noted the similarities between metals and cells Science fiction Bose wrote Niruddesher Kahini, first science fiction in Bengali language. Later, he added the story in the Abyakta book as Palatak Tuphan

Science Page 44 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

as Palatak Tuphan Bose and patents The inventor of "Wireless Telecommunications", Bose was not interested in patenting his invention. Bose made his inventions public in order to allow others to further develop his research Legacy Bose's place in history has now been re-evaluated, and he is credited with the invention of the first wireless detection device and the discovery of millimetre length electromagnetic waves and considered a pioneer in the field of biophysics. Many of his instruments are still on display and remain largely usable now, over 100 years later. They include various antennas, polarisers, and waveguides, which remain in use in modern forms today. In 2012, Bose's experimental work in millimetre-band radio was recognised as an IEEE [Institute of Electrical & Electronics Engineers] Milestone in Electrical and Computer Engineering, the first such recognition of a discovery in India

CNR Rao

Announcing the award of the Bharat Ratna to Chintamani Nagesa Ramachandra Rao, 79, is a big boost for blue sky scientific research in India. It is in recognition of what the renowned chemist, Prof. C.N.R. Rao as he is popularly known, has contributed to painstaking advanced scientific research by publishing nearly 1,500 papers in leading scientific journals and 45 books over the past five decades. He is also one of the few scientists in the world who is a member of all major scientific academies in the world. Such prolific work is usually acknowledged only in the rarified and exclusive world of science academia and research. Rao will be the third for contribution to science from among the 43 chosen for the country’s highest civilian honour. He is the second researcher after the Nobel Prize winning physicist Sir C.V. Raman for pioneering in the fundamental research. Raman was awarded it way back in 1954. The only other person chosen for the award from the world of science, years after he made his striking contribution, was A.P.J. Abdul Kalam in 1997 for the stellar role he essayed in developing India’s integrated missile programme and the Pokharan II nuclear tests which have served as immense and valuable contribution to scientific research and modernization of defence technology. It was, five years on, that he became President of India who gives away the Bharat Ratna. Rao was thinking of joining IISc for a diploma or a postgraduate degree in chemical engineering after obtaining bachelors degree from Mysore University in 1951 but destiny took him to Banaras Hindu University (BHU) where he got admitted for a MSc course. MIT, PennState, Columbia and Purdue offered admission with financial support, but Rao chose Purdue, where he completed PhD in two years and nine months, a record of sorts. Life was on a swing for Rao but home pull prevailed and in 1959 he landed in Bangalore to join the IISc as a lecturer on a monthly salary of Rs 500. Later, anchored at the Indian Institute of Science, Rao made pioneering and international noteworthy contribution to solid state & materials chemistry. He has also been a visiting professor at Purdue University, the University of Oxford, the University of and University of California, Santa Barbara. He was the Jawaharlal Nehru Professor at the and Professorial Fellow at the King’s College, Cambridge during 1983-1984. His work on transition metal oxides has led to basic understanding of novel phenomena & the relationship between material properties & the structural chemistry of these materials. He has made immense contributions to

Science Page 45 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

material properties & the structural chemistry of these materials. He has made immense contributions to nanomaterials over the last two decades besides his work on hybrid materials. He is the founding president of the Jawaharlal Nehru Centre for Advanced Scientific Research in Bengaluru which has since it was started in 1989, to mark the Nehru centenary, been engaged in promoting scientific research and training at the frontiers of science and engineering. He has received Honorary Doctorates from nearly 60 universities including Bordeaux, Caen, Colorado, Khartoum, Liverpool, Northwestern, Novosibirsk, Oxford, Purdue, Stellenbosch, Universite Joseph Fourier, Wales, Wroclaw, Notre Dame etc. He is a member of many of the world’s scientific associations, including the U.S. National Academy of Sciences, American Academy of Arts and Sciences, the Royal Society (London; FRS, 1982), French Academy, Japanese Academy, Serbian Academy of Sciences and Arts and the Pontifical Academy. The prestigious honour has been announced just days before a road underpass connecting Malleswaram and Yeshwantpur, named after C.N.R. Rao, is opened in Bangalore. He had also been given the honours Padma Shri and Padma Vibhushan by the Indian Government and Karnataka Ratna by the Karnataka state government. He has won several other international prizes and awards. He was awarded Dan David Prize in 2005, by the Dan David Foundation, Tel Aviv University, which he shared with George Whitesides and Robert Langer. In 2005, he was conferred the title Chevalier de la Légion d’honneur (Knight of the Legion of Honour) by , awarded by the French Government. He is a foreign fellow of Bangladesh Academy of Sciences. He was also awarded an honorary Doctor of Science by the University of Calcutta in 2004. Dr Rao has also been conferred with China’s top science award for his important contributions in boosting Sino-India scientific cooperation. The award was given by Chinese Academy of Sciences(CAS) in January 2013, which is China’s top academic and research institution for natural sciences. He is the first and only Indian to reach the h-index of 100, reflecting the enormity of the body of his published research work. Translating the feat into common man’s parlance, scientists say Rao’s achievement is equivalent to scoring 100 international centuries. The h-index was first described in 2005 by physicist Jorge Hirsch. A scientist’s h-index is the greatest number of papers he or she has published that have each amassed at least that many citations. Dr Rao, incidentally, is the only Indian scientist and among a handful in the world with close to 50,000 citations, which puts him in the league of the biggies of science.

Indian scientist's EDK (Explosive Detection Kit)

• Explosive detection kit, developed by DRDO • EDK (Explosive Detection Kit) kits have been successfully used in preventing several terrorists' attacks & even immediately detecting the type of explosive used in the event of a bomb blast • This little box can work as a pre-blast analytical tool and as a post-blast investigative tool • A few drops of four reagents contained in four vials can detect explosives based on TNT, RDX, dynamite, & black powder within minutes with no more than 3 to 5 milligrams of the suspected sample. It also does not require field calibration, power or peripheral devices.

Engineer Chitra Thiyagarajan's plastic-to-fuel device

• Engineer Chitra Thiyagarajan has developed a unit that converts plastic waste into a fuel similar to diesel. • All plastics except PET bottles are put in a chamber and heated in the absence of oxygen over chromium micro band heaters (similar to those used in water immersion rods) to temperatures of between 350oC and 375oC. The gas generated passes into another chamber with a water coolants coils on two sides. It is then pumped into another compartment half-filled with water. The fuel floats on the surface. Non-soluble gas that passes into a condenser can be used as an LPG alternative. • The device is not expensive and requires just three hours to generate fuel. • A 5kg unit costs around Rs 75,000 and a 25 kg variant, Rs 3 lakh. • Each kg of plastic produces 800ml of diesel.

Indians contribution to Technology

19-05-2014 How Indians have contributed to technology? The story of India’s/Indian/Indian-American contribution to technology is not new Satya Nadella's elevation as CEO of Microsoft marks the acme of global corporate leadership attained in recent years by first generation Indian immigrants. While at Pepsico, at CitiBank (who has since stepped down), Ajay Banga at Mastercard, and Anshu Jain at Deutsche Bank have already scaled the dizzy heights, Nadella's ascension was a landmark event given Microsoft's high profile and its close association with India, fuelled in part by a large section of its workforce being of Indian origin. Sundar Pichai, the man behind Chrome and Android; Gundotra, the person behind Google+, Ajay Bhat invented the USB. (The figure of 33 per cent Microsofties being of Indian origin is hyperbolic; it is less than 10 per cent, and from what Bill Gates told this correspondent several years back, it is about 20 per cent in the engineering division.)

The story of India's/Indian/Indian-American contribution to technology is not new; it goes back at least couple of decades, possibly more. Back in the 1990s, when I was working on a book that was eventually titled The Horse That Flew: How India's Silicon Gurus Spread Their Wings, a librarian who was helping me with research would pull my leg about India having invented zero ("THE zero,'' I'd correct her), as we scoured the archives for stories about Indians in the science and technology fields. The idea for the book was triggered by then "hot male'' Sabeer Bhatia's sale of Hotmail to Microsoft for $ 400 million. Shortly before that, Vinod Dham had been instrumental in launching the

Science Page 47 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Hotmail to Microsoft for $ 400 million. Shortly before that, Vinod Dham had been instrumental in launching the Pentium chip, and Ram Shriram (who would later fund Google and become a billionaire) was a key figure in Netscape, the early browser favorite. Years before, Narendra Singh Kapany had done pioneering work in fiber optics, C. Kumar Patel was recognized for cutting edge work on lasers, Arun Netravali led the team that developed high-definition television (HDTV), and Praveen Chaudhari held patents for the erasable read-write Compact Discs, the kind you burned music on a generation back. I chronicled several such stories in my book. However, Indians in the management and corporate side of things was a different deal altogether. There was the inevitable talk of a glass ceiling, and it was rare that an Indian went on to become CEO of a company, although several, like Vinod Khosla, Umang Gupta, and Kanwal Rekhi, had founded companies and even helmed them briefly. White- dominated America was leery of showing a minority face at the helm. It was only in the nifty noughties (2000 onwards) that things began to change, in keeping with the changing demographics and ethos of the US itself, and the self-belief and critical mass Indians attained, riding on the exploits of the pioneers. In 2004, Surya Mohapatra, an alumnus of Sambalpur University and Regional Engineering College-Rourkela, his Odiya accent untainted by decades in the US, was appointed CEO of Quest Diagnostics, a Fortune 500 company. Indra Krishnamurthy Nooyi, who went to one of her first interviews in the US in a sari after her professor advised her to "be yourself,'' was elevated at PepsiCo in 2006. Nagpur-born Vikram Pandit at Citibank, Francisco D'Souza, son of an Indian diplomat, at Cognizant, and Adobe System's Shantanu Narayen, like Nadella a Hyderabad native, all scaled the top in 2007. Ravi Saligram at OfficeMax and Sanjay Mehrotra at SanDisk would make the grade by the end of the decade, when there were at least ten CEOs of Indian origin in the Fortune 500. The numbers compared favorably with Blacks (six CEOs), Hispanics (eight), and other Asian-Americans including Chinese, all of whose population was several times larger than that of Asian-Indians in the US. There were several reasons attributed for this success by a number of experts I spoke to. They ranged from the Indian comfort with English and ease with numbers, to the fact that most Indian immigrants came from the relatively creamy layer of Indian society (although several achievers spoke to me about the tough grind they went through in India, from studying by candle light to walking miles to school). It all boiled down to hard work, initiative, and a hunger for success, topped off with some luck, in an American ecosystem that recognized merit better than in India. But fundamentally, it also went back to a society that manages the paradox of at once being religious and superstitious and at the same time fostering a scientific temper and a spirit of inquiry; or at a higher level, balancing science and spirituality. For instance, India is very familiar with Swami Vivekananda and his epic tour of America to address the Congress of Religions in Chicago in 1893. Less well known is Vivekananda's extensive engagement, pursuant to his interest in science and spirituality, with Nikola Tesla and Thomas Edison, the pioneers of all things electric. A decade or so later, a young man named Gobind Behari Lal, a nephew of the Indian nationalist Lala Hardayal, left India to come to the University of California-Berkeley, on a scholarship. Following his post-doc, he joined Hearst Newspapers as a "science writer,'' the first time the designation was used in an American newspaper. In a career that lasted more than half a century, he interviewed such formidable scientific titans as Albert Einstein, Enrico Fermi and Max Planck, winning a Pulitzer Prize (1937) on the way, the first for an Indian-American (Jhumpa Lahiri would come decades later, much after Lal died in 1982). His work inspired a generation of Indian-Americans who streamed into the sciences and technology.

Little of this was known in India, which on account of its own constricting policies and a lack of opportunity, gave up some of its best and brightest to the US, which on its part used its immigration policy to attract them. From 1965 onwards, when immigration rules were relaxed for Indians, more than a million educated Indians have streamed into the US for "higher studies,'' many of them staying behind to become "Indian-Americans,'' and often, particularly in case of their children, just "Americans.'' Few who have been in the US for more than 20-25 years and who have taken US citizenship bear any allegiance to India, and many of them find the media hysteria in India over their achievements quite cringe-worthy

Intellectual Property Rights (IPR) 06 February 2014 18:03

• IPR includes copyright, trademarks, geographical indications, designs, trade secrets, business confidential information & data etc.

What are Intellectual Property Rights? • Broadly IPR are rights granted to creators and owners of works that are results of human intellectual creativity • These works can be in industrial, scientific, literary and artistic domains, and in the form of an invention, a manuscript, a suite of software or a business name • IPR as a collective term includes the following IP rights- ○ Patent ○ Copyright ○ Trademark ○ Registered Industrial Design ○ Protection of IC layout design ○ Geographical Indications ○ Protection of undisclosed information WHY do we need Intellectual Property Rights? · Due to globalization, geographical barriers to trade among nations are collapsing, leading to emergence of multilateral trade and a new economic order. · The new knowledge economy places a tag of urgency, as the time for grasping knowledge has become an important parameter to determine the success of an institution, enterprise, government and industry. · The face of changing trade environment is characterized by global competition, high innovation risks, short product cycle, need for rapid changes in technology and high investment in R&D. · Thus the complexity of global trade would be on the increase with introduction of more and more variables. Many product and technologies are simultaneously marketed and utilized in many countries. All such products and technologies are susceptible to infringement leading to inadequate returns to the creator of knowledge. Developers of such products and technologies would like to ensure the R&D costs and other associated costs are recovered and enough profits are generated to invest in future R&D. Hence there is a need for Intellectual Property Rights. NATURE of Intellectual Property Rights · Largely territorial except Copyright, which is global · Awarded by the state and are monopoly rights. · Have to be renewed from time to time. (Except Copyright and Trade Secrets) · Have fixed term. (Except Trade Secrets, Geographical indications and Trademark which have indefinite life) · Can be assigned, gifted, sold and licensed like any other property. · Can be simultaneously held in many countries at the same time. · Can be held only by legal entities. PATENTS

PATENTS · Exclusive rights granted by a country. · Granted to the owner of an invention. · Granted for making, using, manufacturing and marketing the invention · Available for a limited period. · Territorial in nature, i.e. inventor needs to file separate patent applications for different nations. Definition of Invention i. A new product or process involving an inventive step and capable of industrial application ii. New invention means any invention which has not been anticipated by any publication in the country or elsewhere in the world. iii. An invention must be -NOVEL (Undisclosed in public, through any publication, anywhere in the world) -NON OBVIOUS (Not obvious to person skilled in the subject matter of the patent) -USEFUL

World Intellectual Property Organisation (WIPO)

15-01-2016 Dr.Tilak HR • WIPO is the global body for promotion & protection of intellectual property rights (IPR) • It encourages & provides assistance to all its 188 member countries in formulating a national IPR policy, however WIPO does not dictate or prescribe any mandatory measures • To ensure the successful implementation of an IPR policy, creating awareness among all stakeholders is a sustainable approach rather than just relying only on punitive measures • In the WIPO's Global Innovation Index 2015 that surveyed 141 economies in the world, India’s was ranked 81

Digital Piracy

26-06-2014 US govt panel puts India on piracy watch list • India is named in the ‘International Piracy Watch List’ by a US govt panel that is looking to highlight countries that are doing little to address high rates of digital piracy • It said that India has extremely high rates of camcording piracy, high levels of unlicensed software use by enterprises, & a lack of effective notice-&-takedown procedures for online piracy • A new study recently pointed out that online piracy levels in India remained at 60% (unlicensed rate) • According to non-profit organisation BSA, India is 2nd only to China in the Asia Pacific region in terms of commercial value of unlicensed software sold in 2013

Copyrights

23-10-2015 Copyright does not exist for title of a literary work • The Supreme Court held that no copyright exists for the title of a literary work

Geographical Indication (GI) status

09-06-2015 • The Geographical Indications of Goods (Registration & Protection) Act, 1999 provides for the registration, the protection against infringement, & also protection for authorised users ○ Eg. of GI in India: Muga silk makers of Assam, Mysore Sandal soap, Darjeeling tea, the Thanjavur Veena, Banarasi Silk • Our people have always been closely linked with the soil, the vegetation, in short the local environment to make or

• Our people have always been closely linked with the soil, the vegetation, in short the local environment to make or grow our products • So, the promotion of GI has other socio-economic & environmental benefits besides just the protection of IP • It was found that the GI status of the product is not utilised to its potential, the stakeholders are unaware of the value of their GI & its benefits, the quality of these products is not standardised, & even when made by genuine persons, the quality varies • Also, the market for the products & the pricing are fragmented • GI owners also have a role to play in promoting their GI, but the undeniable reality is that many of them come from groups that are less vocal & less powerful than say trademark or patent owners • A Geographical Indication or GI is India’s strength. Practically everything we grow or make is linked to a region. This right has to be strengthened & protected

Indian IP Regime 30 September 2014 17:06

• Intellectual property & patents give companies an edge to compete in the competitive global markets

In defence of Indian Patent regime • For the last several years, US drug majors & their European counterparts have lobbied hard to demonise the Indian patent regime ○ But Indian govt must continue to defend the law & stand its ground • India is not the only country axing bad patents ○ A 2012 study found that US district courts invalidated patents in almost 90% of the cases that came before them ○ And yet, India continues to be singled out •

Indian Patents Act, 2005

• The Patent Act provides measures by way of compulsory licensing (CL) to ensure that the patents do not impede the protection of public health & nutrition, & the patent rights are not abused by the patentee (monopolisation)

Compulsory Licensing (CL)

• A compulsory license is a statutorily created license that allows certain parties to use or manufacture a product encompassed by the claims of a patent without the permission of the patent owner (patentee) in exchange for a specified royalty • The Indian Patent Act, 2005 contains very broad compulsory licensing provisions ○ Two provisions of the Act that allow for compulsory licenses are Sections 84 & 92 • India’s Patent Act provides for broad compulsory license provisions that are not limited to just pharmaceutical products but encompass products from any technology

Section 84: • Grant of Compulsory License due to ‘Non-Working/Unaffordable Prices of Patented Article • Under it, the Controller of Patents can issue CL 3 yrs after the issuance of a patent if 1 of the following conditions is met: 1. The reasonable requirements of the public with respect to the patented invention have not been satisfied; or 2. The patented invention is not available to the public at a reasonable price; or 3. The patented invention is not worked in India • Section 83 implies that the working of the patent cannot be taken to include ‘imports’ ○ ie. The patentee cannot hold the patent in India & import the product from another country, thereby compelling the Indian consumer to pay an excessive price Public Accommodation: The Act contains a list of circumstances in which the “reasonable requirements of the public” will be considered not met: I. The patentee does not grant a license on “reasonable terms” thereby causing: 1. a disadvantage to a trade or industry or the development or establishment of an industry in India 2. demand for the patented product not to be sufficiently met or available on reasonable terms 3. insufficient supply or development of a market in India for the exportation of the patented article 4. a disadvantage in the establishment or development of commercial activities in India II. The patentee imposes conditions with respect to the grant of license, sale or use of a patented product or process, the manufacture, use or sale of non-patented materials or the establishment or development of any trade or

Science Page 53 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

the manufacture, use or sale of non-patented materials or the establishment or development of any trade or industry in India, which is prejudiced III. The patentee includes one or more of the following conditions in a license: 1. an exclusive grant-back clause for any improvements developed by the licensee on the patented product or process 2. a clause prohibiting the licensee from challenging the validity of the licensed patent(s) 3. a clause that is essentially a “coercive” package license (namely, requires the licensee to purchase non-patented items from the patentee as a condition of the license) IV. The patentee does not work the patented invention in India to the fullest extent possible or on a commercial scale to an adequate extent V. The working of the patented invention on a commercial scale in India is being prevented or hindered as a result of the importation of the patented invention by: 1. the patentee or a person authorized by him 2. persons purchasing from the patentee, either directly or indirectly 3. the infringement of the patent by a 3rd party against whom the patentee is not taking or has not taken any action to eliminate the said infringement Reasonable Price: • CL will be granted if a patented invention is not being made available to the public at an affordable price • For eg., Bayer was selling Nexavar® for about Rs 280,000/mth compared to Natco selling the drug for about Rs 8,800/mth Worked in India: • CL will be granted if the patented invention is not worked in India • An invention is considered to be “commercially worked” in India if the patented invention is: (a) manufactured in India; (b) imported into India; (c) licensed & forms a part of a product that is sold in India; or (d) commercialized in India in any other manner • In the case involving Nexavar®, a non-exclusive, non-assignable license was given Natco. In addition, the royalty awarded was 7%

Section 92 CLs can be granted on notification by Central Govt: • In a case of a national emergency (including a public health crisis), extreme urgency or in the event of public non - commercial use; [Section 92(1)]; or • For export [Section 92A(1)] Emergency: • The granting of compulsory licenses under section 92(1) cannot be challenged by the patentee either through an opposition proceeding or in court For export of Pharmaceutical Products: • Article 31(f) of the TRIPS Agreement undermined the need for the availability of medicines to the countries having less or no manufacturing capacity through importation from other countries ○ WTO adopted a mechanism to resolve this problem by implementing Para 6 of the Doha Declaration on TRIPS Agreement & Public Health in August, 2003 • The Indian Patent Act was thus amended in Jan, 2005 & Section 92 (A) was incorporated for grant of CL for export of pharmaceutical products in certain exceptional circumstances

Analysis • It is to ensure that the patents do not impede the protection of public health & nutrition • The CL therefore serves to strike balance btw 2 disparate objectives- rewarding patentees for their invention & making the patented products, particularly pharmaceutical products, available to large population in developing & under developed countries at cheaper & affordable cost • CLs allow 3rd parties to exploit a patented invention without the consent of the patentee ○ Some claim that it deprives patentees of their most important right ie. the right to say ‘no’ to the exploitation of their invention by the 3rd parties • CLs are usually granted through administrative procedures managed by a govt body CLs history in India • In March, 2012, India’s first CL was granted by the Patent Office (PO) to Natco Pharma Ltd. (Indian generic drug manufacturer) for producing generic version of Bayer Corporation’s patented medicine Nexavar (sorafenib

Science Page 54 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

manufacturer) for producing generic version of Bayer Corporation’s patented medicine Nexavar (sorafenib tosylate), used in the treatment of Liver & Kidney cancers • The Patent Office decided Bayer on all the 3 grounds in the Patents Act for the grant of CL - 1. reasonabe requirements of the public not being satisfied 2. non-availability to the public at a reasonably affordable price 3. patented invention not being worked in the territory of India • Among other important terms & conditions of the CL were directions to Natco to manufacture the patented drug only at their own manufacturing facility, selling the drug only within the Indian Territory & supplying the patented drug to at least 600 needy & deserving patients per yr free of cost • Aggrieved by the PO’s decision, Bayer immediately moved to the Intellectual Property Appellate Board (IPAB) alleging that the grant of CL was illegal & unsustainable ○ In March, 2013, IPAB upheld PO's decision to grant CL to Natco Pharma Ltd. ○ IPAB said that the right of access to affordable medicine was as a matter of right to dignity of patients

07-03-2014 Targeting India’s IP laws undermines WTO’s legitimacy • A Geneva based inter-governmental organisation of developing countries has slammed US & developed world countries for pressurising India over its IP laws • It said that targeting Indian IP laws undermines the legitimacy of WTO • Indian IP laws are fully in line with the TRIPS agreement, & reaffirmed by the Doha Declaration on TRIPS & public health • The USTR Special 301 review for 2014 alleged that India lacks adequate & effective protection of IPRs • India & other developing & least developed countries have the right to use the flexibilities in the TRIPS Agreement to the fullest extent for advancing public health needs & other development priorities

10-03-2014 USIBC opposes IP violator tag for India • A top US trade advocacy group US-India Business Council (USIBC) has told the USTR that it strongly recommends against India being designated a Priority Foreign Country as being advocated by influential pharmaceutical lobbying groups

24-03-2014 • Differences over IPRs have emerged as a strong undercurrent in India’s economic relations with the US • It is an attempt by the influential pharma lobby to stymie India’s efforts to ensure the supply of medicines at affordable rates without violating existing treaty commitments • Due to influential big pharma lobbies in the US, India was designating as a “priority foreign country” in USTR 2014 Special 301 Report ○ This label is reserved for the worst offenders of IPRs, & as a follow-up the US could impose trade sanctions such as withdrawing tariff preferences for Indian exports • India is applying the flexibilities that are available in the existing TRIPS (Trade Related Aspects of Intellectual Property Rights) Agreement Tracing back • In Uruguay Round of trade talks (1994), India managed to incorporate certain flexibilities in the TRIPS agreement • In 2005, India incorporated patent protection into domestic laws. Since then, it has used the flexibilities only twice ○ In March 2012, it issued a compulsory licence to an Indian firm for a cancer drug, whose patent-holder, the German multinational Bayer, had priced it well beyond the reach of a majority of Indian patients • Under another provision, countries have the option to deny a patent to a drug that involved only incremental innovation over an existing drug ○ In April 2013, the Supreme Court upheld the 2006 decision of the Indian Patent Office denying the Swiss multinational Novartis patent on a drug that involved only incremental innovation • The real issue is not about these two instances but the prospect of other countries emulating India has rattled big pharma • India, which has not violated the treaty obligations, can challenge any prospective action by the US by taking it before the WTO, whose dispute settlement mechanism has a good record of impartiality • Developing countries & a few developed ones are on India's side to safeguard its domestic commitment to public health

28-03-2014 • The Global Intellectual Property Centre’s (GIPC) International IP Index notes India as having the “weakest” IP environment on the list of 25 carefully chosen countries that figure in the index ○ GIPC is an affiliate of the US Chamber of Commerce

USTR's Special 301 report

Basics • Every year, the USTR releases the Special 301 reviewing the global state of IPR protection & enforcement • The exercise involves categorising countries based on their IPness • The good ones are praised & commended for strengthening their IP regime • The not so good ones are put either on the “Watch List” or the “Priority Watch List”, indicating that particular problems exist in those countries with respect to IPR protection, enforcement or market access for persons relying on IPR • The really bad ones are named as “Priority Foreign Country” for having “the most egregious acts, policies, or practices have the greatest adverse impact (actual or potential) on the relevant US products” Targeting India • India has been at the receiving end for uniquely incorporating a remarkable array of TRIPS flexibilities into its patent law, which includes higher standards of patentability, a pre-grant challenge mechanism for patents & a robust compulsory licensing regime • Since becoming a member of the WTO, India has never been categorised as a Priority Foreign Country • The GIPC’s push in urging the USTR to designate India as a Priority Foreign Country has more to do with what is happening outside India than within it • These actions appear to be directed towards putting an end to the leadership role played by India in devising an alternative TRIPS compliant patent regime • The Indian example offers to other countries a legitimate way of complying with the TRIPS agreement • Countries like the Philippines, Brazil & South Africa have either emulated or strongly favour following India’s path • In a world devoid of alternative approaches to protecting intellectual property and promoting access to inventions, India’s path is refreshingly fresh & balanced

19-04-2014 • US pharmaceuticals sector, & trade lobbies putting pressure on US govt to put India under the ‘Priority Foreign Country’ list for IPR (which may lead to trade sanctions on India) ○ Under the US Trade Act, a Priority Foreign Country is the worst classification given to those which deny adequate & effective protection of IPR or fair & equitable market access to American trade relying on IPR protection • India’s IPR regime is totally compliant with global laws, including the WTO

01-05-2014 USTR retains India on IPR ‘Priority Watch List’ for 2014 • US has retained India on the ‘Priority Watch List’ of nations in the US Trade Representative’s (USTR) ‘Special 301’annual report 2014 on global intellectual property rights (IPR) regimes, on the basis that there were “growing concerns with respect to the environment for IPR protection & enforcement in India” • The report urged India to address concerns such as online piracy & ‘çamcording incidents’ affecting the film industry, to promote predictability in patent laws including the question of section 3(d) of India’s Patent Act & tackle “concerns” stemming from Section 84 of the Act & the Intellectual Property Appellate Board’s support for the grant of compulsory licenses

02-05-2014 • USTR to look at Out-of-Cycle Review focused on India ○ The out-of-cycle review echoes India’s emphasis on strong govt-to-govt & govt-to-private sector engagement, as the most effective means for resolving concerns in this area • India & the US have agreed to hold Commerce Secretary-Deputy USTR level talks • The two sides will also have dialogue in a Trade Policy Forum (TPF) meeting btw USTR & Union Commerce Minister of India (TPF has not met since 2010)

Science Page 56 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

of India (TPF has not met since 2010)

02-05-2014 • India said that its IP policy is WTO-compliant & it won’t support unilateral US probe ○ the investigation was unilateral as it was under the US Trade Act

02-05-2014 The two allegedly problematic features of India’s IPR regime are • Section 3(d) of India's patents act, which prevents companies from being able to evergreen patents by making minor alterations to compositions (for which Novartis lost its Glivec case) • Compulsory Licensing, by which the govt, on a case to case basis, allows a generics manufacturer to produce patented drugs in the public interest, without the consent of the patent holder In defence of India • The developmental imperatives of countries like India are understandably different from the US • India can also use these mechanisms carefully (not indiscriminately) ○ ie. Compulsory licensing should be used as a last resort

12-05-2014 Defending India’s patent law • If Gleevec was refused a patent, it is only coz it failed the test of Indian law ○ India's Supreme Court rejected drug maker Novartis AG's attempt to patent a new version of a cancer drug Gleevec ○ Healthcare activists say ensures poor patients around the world will get continued access to cheap versions of lifesaving medicines • The Novartis case & the Nexavar case of compulsory licence (CL) are worrying US pharma cos Tracing back • Innovation & invention have speeded up in myriad ways in the last few decades • TRIPS recognises that members have the right to use/adopt measures to protect public health so long as they are consistent with TRIPS ○ The Doha Declaration is an affirmation of the right to use the flexibilities in TRIPS, especially by developing & less developed countries, regarding access to medicine ○ The language of the Doha Declaration emphasises the importance of implementing and interpreting the TRIPS Agreement in a way that supports public health • India is committed to the obligations under the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) ○ Therefore, it was necessary for India to revisit its patent law; in 2005, the Indian Patents Act was amended, Section 3(d) being one of the amendments • Analysis ○ The TRIPS agreement does not limit the grounds on which compulsory licences can be granted, & does not prevent patent applicants from having to demonstrate enhanced efficacy for their allegedly new & useful inventions ○ India’s laws & experiences could provide a useful example for low- & middle-income countries worldwide • Through its Patent law, India has attempted to balance its obligations under the international treaty & its commitment to protect & promote the public health in India & elsewhere

Ever greening of Patent • The intellectual property of the inventor lies in the invention which is claimed to be novel, inventive & patentable • The patent is a creature of law by which the state bars public access to that invention for a fixed period • The economic reward from the invention is earned during this time after which it goes to the public domain Section 3(d) is a test of patentability • Section 3(d) says that in the absence of evidence of enhancement of known efficacy, the mere discovery of a new form of a new substance is not an invention deserving the grant of patent • In case of Novartis, Imatinib Mesylate was the known substance & Novartis claimed a patent for its beta-crystalline form ○ All the pharmacological properties of beta crystalline form of Imatinib Mesylate are equally possessed by Imatinib in free base form or its salt

Science Page 57 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Imatinib in free base form or its salt • It means any new forms of known substances which do not have enhanced efficacy are in effect advances without real innovation. Hence, Section 3(d) is actually a catalyst for genuine inventions ○ Filtering doubtful patents is the strength of our law & not its weakness Compulsory Licensing (CL) • Anslysis ○ The mechanism of CL is essentially about balancing patent rights with access to medicine ○ The words “social & economic welfare,” “public health,” “national emergency” & “public health problems/crises” used in the Act are all pointers to the CL provisions being centred around access to medicine ○ In all these years, there has been only one instance (Bayer vs. Natco case) of the grant of compulsory licence. In fact it was refused recently for Dasatinib

23-06-2014 • India should be prepared to challenge any unilateral action by the US before the WTO whose disputes settlement mechanism has a good record of impartiality • The way forward is through discussions not confrontation ○ India needs foreign technologies & investment ○ There is a case for having a permanent mechanism for discussing patent-related issues, especially concerning the drug industry • Points in India’s favour are - ○ patent issues are decided after a due process, never arbitrarily ○ very few instances of using flexibilities are indicates that India uses those safeguards selectively ○ Recently, despite strong recommendations from the Health Ministry, the govt refused to issue CL for production of a copy of Bristol-Myers Squibb’s cancer drug Dasatinib in India

13-10-2014 • PM Modi & Obama committed to establishing an annual intellectual property (IP) working group as a core element of the bilateral trade policy forum. US industry widely welcomed this statement. • Recently Modi govt. announced plans to establish an overarching intellectual property policy that, in concept, would both define India’s approach to intellectual property and enhance the clarity and transparency of its relevant laws. • With this new approach India has an opportunity to establish a legal and regulatory framework that solidifies its future economic competitiveness and unleashes its vast innovative potential. • The WTO agreement on Trade-Related Aspects of Intellectual Property Rights clearly commits parties to a three- step patentability test of novelty, inventiveness and industrial applicability. In the pharmaceutical space, the addition of “enhanced efficacy” as a fourth step in Section 3(D) in India seems to cause problems for Foreign companies. • India has an enormous backlog of pending patent applications. Steps to streamline the bureaucratic process and provide essential administrative and judicial tools for fair, transparent resolution of disputes would be an important contribution to an enhanced Indian environment for innovation.

16-10-2014 US launches review of India’s Intellectual Property Regime • The USTR’s ‘Out-of-Cycle’ (OCR) Review follows the 2014 Special 301 Report that came out in April, in which the U.S. Trade Representative (USTR) had placed India on the ‘Priority Watch List’ • Specifically, the out-of-cycle review is focused on engagement, what type of engagement has India pursued in terms of intellectual property. • Prime Minister Modi and President committed to establish an annual high-level Intellectual Property (IP) Working Group with appropriate decision-making and technical-level meetings as part of the TPF during the former's visit to US.

30-10-2014 Why India’s record is seen as dismal • a constant irritant for global pharma is a provision of the Indian Patents Act, Section 3(d) • The main content of 3(d) is to do with an “efficacy clause”, which states that the new form of a known substance would only be entitled for a patent if it resulted in the enhancement of a known efficacy of that substance

Science Page 58 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

would only be entitled for a patent if it resulted in the enhancement of a known efficacy of that substance • In other words, drugs with minor improvements, or “evergreened” drugs, will not be eligible for patents unless they are proven to have “extra” efficacy • Section 3(d) has become the basis of patent offices rulings, court injunctions, & judgments in several cases • It includes rulings on Novartis’s Glivec (an anti-cancer drug), Boehringer Ingelheim’s nevirapine (an anti-HIV drug), Glaxo’s lapatinib (anti-cancer) & Allegan’s two HIV drug patents • The efficacy clause of Section 3(d) is usually seen only as a health safeguard that restricts patents on drugs which lack the novelty criterion and therefore permits the play of generic drugs, cheaper and more accessible, in the market • If novelty is the foundational edifice of the global patent regime then India actually exhibits greater compliance with the original idea of novelty • India has often been accused of not being TRIPS compliant • But Article 27 of TRIPS agreement says that patents will be available for “novel” inventions, capable of industrial application, ironically “novelty” is left undefined • This means that member states can adopt their own understanding of what is novel, varying in stringency, depending on what suits their national & rational agendas Strategy to “evergreen” blockbuster patented drugs This strategy entails making slight improvements on the basic invention through new drug delivery systems, new dosage forms etc, and claiming multiple patents on these minor improvements, thus extending the patent life of the drug The debate on what constitutes efficacy, invention and novelty is likely to get more intense • more countries planning to incorporate 3(d)-type precautionary principles in their patent legislations • Philippines & Argentina already have similar patent legislation • It is important that we not only assert the potential of progressive legislations like 3(d), but also leverage the sovereign space of co-equal rights

04-11-2014 MNCs, industry bodies back India’s IP regime • Multinational organisations including PepsiCo and industry associations like Indian Pharmaceutical Alliance (IPA), have come in favour of India’s intellectual property regime, which is being reviewed by the US administration • Between January 2005 and 10 October 2014, India has granted 1,039 patents to domestic companies, while 3,575 patents have been granted to foreign firms Proactive steps by India • global recognition of the attractiveness of India as destination of FDI • willingness to engage in dialogue to remove impediments to FDI • making of IP policy & its implementation & evolving jurisprudence • to recognize the concerted efforts being made to improve functioning of Indian Patent Office

15-11-2014 • initiation of the Out-of-Cycle Review (OCR) by USTR which evaluates whether there has been any meaningful progress in engaging India’s new government on intellectual property (IP) concerns • compulsory licence was issued for Nexavar, a drug to treat kidney and liver cancer, over which Bayer held a patent (Nexavar was priced at $4,700 per month) • SC denied patent protection on Glivec, a drug owned by Novartis • Interestingly, in the past year the US Supreme Court overturned the decisions of the Federal Circuit in five out of the six considered patent disputes • US & India agreed to set up a high-level Working Group on IP within the Trade Policy Forum (TPF), which is evidence of India’s commitment to have a substantive good faith dialogue on IP concerns • with the establishment of WTO, the role of the USTR in policing the world with the threat of unilateral sanctions appears highly questionable & India should not shy from taking legal recourse at the WTO should the U.S. impose such sanctions • The US Pharma lobby is pushing for changes in India’s patent laws & refuses to recognise India’s legitimate public policy concerns & the flexibilities established as an outcome of international trade negotiations • India should be careful not to dismantle a hard-bargained & well-established structure of the existing patent system • India must use the access that the TPF will provide to address protectionist hurdles that Indian goods and services face in the US

face in the US • India will seek to address concerns on geographical indications (GIs), online piracy of Indian movies & traditional knowledge (TK) in the agenda of the Working Group • the Working Group on IP can serve as a platform where real time solutions to meet India’s need for low cost medicines can be addressed • India should emphasise that one way to avoid unpopular compulsory licensing is to instead focus on fostering a climate whereby innovator companies are encouraged to voluntarily license in collaboration with Indian generic companies much like Gilead has done recently to bring down the price of a hepatitis C drug by licensing to 8 generic companies • India can achieve meaningful results by engaging with industry experts to use the Working Group on IP as forum for setting tangible & realisable goals that will benefit constituents on both sides

15-12-2014 Generic drug makers get a boost from SC ruling • In a significant development for the pharmaceutical industry, the Supreme Court has rejected multinational Bayer’s appeal to block production & sales of the low cost version of its kidney cancer drug, sorafenib tosylate (branded as Nexavar), by Natco Pharmaceuticals • Hyderabad-based Natco was granted the first and to date only compulsory licence (CL) by the government in 2012 to make and sell a patented drug at a fraction of the price at which it was sold by the patent holder, Bayer • The intention is to have wide reach, accessibility and affordability for medicines • The development will act as a fillip for generic manufacturers and encourage manufacture of affordable drugs to increase accessibility • Being the first and only CL granted by the government to date, it is definitely a positive development for Indian generic drug manufacturers

14-07-2015 • India has been recognised by the World Intellectual Property Organization as the 17th International Search Authority & International Preliminary Examining Authority in the world

Voluntary licensing model & other models

27-09-2014 New drug era Alternative forms of licensing • The deal btw Gilead (US pharmaceutical company), & 7 Indian generic firms, to manufacture & distribute an Sovaldi (hepatitis C antiviral drug) in low- & middle-income countries • Sovaldi, a patented hepatitis C drug had revolutionised treatment Analysis • Given the increased patent scrutiny & the mounting pressure of instruments such as compulsory licencing & drug price control, innovators are looking to partner with generic companies for local manufacture & distribution of their drugs at cheaper prices • Concerns ○ On the other side of the fence, the advent of biologics, a species that is often difficult to copy, & increased regulatory pressures are forcing generic firms to ally with drug innovators ○ Growing partnerships btw local generics & global innovators could also mean that public health & affordable access can take a severe beating as it will mean fewer patent challenges ○ Hence, govt cannot relying on free-market competition from the generic sector to bring drug prices down. It has to play a more active role to bring affordable healthcare & revive its pharma PSUs

21-01-2015 Gilead licences Strides to make, distribute AIDS drug in 112 countries • US pharmaceutical major Gilead Sciences has signed a licensing agreement with Bengaluru-based Strides Arcolab, under which Gilead has extended non-exclusive rights to Strides to make & distribute Tenofovir Alafenamide (TAF) • TAF is a novel NRTI used in HIV patients in the treatment of AIDS • In Sept, 2014, Gilead signed agreements with 7 Indian generic drug manufacturers licensing them to make sofosbuvir to supply it to 90 countries • Sofosbuvir is priced at $84,000 per patient in the US, & the effective price for generic version is around $900 & a 10% royalty • Gilead’s chosen voluntary licensing model is refreshing, & will certainly earn it goodwill. It ensures protection of intellectual property (IP) & simultaneously ensures access to medicines • Other multinational pharmaceutical giants such as GSK opt for a price differentiated model for developing markets mainly for their older products, which Merck uses the discounted model, pricing its drugs at 75% of US prices • Pharmaceutical multinationals prefer Indian manufacturers over other generic manufacturing destinations like South Africa & Brazil coz India is already supplying generics to 200 countries & has proven capability, cost- effectiveness & quality

30-03-2015 • In the highly competitive global pharmaceutical market, US pharmaceutical major, Gilead Sciences set a precedent in 2014 by being the first company to offer a 'voluntary licence' for its blockbuster, break-through drug sofosbuvir used in the treatment of Hepatitis C virus (HCV) • The alternative to the voluntary license is the compulsory license, which has been a non-starter in the Indian context with Natco securing India's first & to-date only compulsory licence in 2012 to launch generic version of Nexavar, Bayer's drug for liver & kidney cancer

Nexavar, Bayer's drug for liver & kidney cancer • Other pharmaceutical giants such as GlaxoSmithKline (GSK) & Merck have opted for different models. GSK has opted for a differentiated pricing model for developing markets while Merck follows a discounted model for those markets • Voluntary licensing has the potential to be a trend-setter as it ensures protection of intellectual property (IP) for patent-holders & simultaneously ensures access to medicines, a balance the industry has been striving to achieve

Draft National IPR Policy

• India has been under pressure from foreign countries to strengthen its IP regime, after multinational pharmaceutical firms have had adverse verdicts in recent times

09-09-2014 Centre working on a comprehensive IPR policy • Govt will frame a comprehensive policy on IPR to further strengthen the country's patent regime & deal with issues raised by developed countries • Dept of Industrial Policy & Promotion (DIPP) will also set up a think tank on IPR to deal with the issues being raised by developed nations & protect interest of India on IPR-related

25-10-2014 • 6-member expert group, set up by DIPP to draft the National Intellectual Property Rights Policy & to advice DIPP on IPR issues • The panel, to be chaired by retired Justice Prabha Sridevan The terms of reference • To draft National Intellectual Property Rights Policy. • To identify areas in IPRs where study needs to be conducted & to furnish recommendations in this regard to Ministry. • To provide views on the possible implications of demands placed by the negotiating partners. • To keep the Government regularly informed about the developments taking place in IPR cases which have an impact upon India's IPR Policy. • To advise Govt on best practices to be followed in Trademark Offices, Patent Offices & other Government Offices dealing with IPR in order to create an efficient and transparent system of functioning • To prepare periodic reports on best practice followed in foreign countries. • To highlight anomalies in the present IPR legislations & to advice possible solutions to the Ministry • To give suggestions on the steps that may be taken for improving infrastructure in IP offices & Tribunals • To examine the current issues raised by industry associations & those that may have appeared in media & to give suggestions to the Ministry on such issues The decision assumes significance as the Obama administration in the recent times has been strongly criticising India’s investment climate & IPR laws, especially in the pharmaceuticals & the solar sectors

05-02-2015 The recently released Draft National IPR Policy recognised the fundamental links btw IP, innovation & the successful development of innovative products

03-05-2015 • the industry was surprised with the PM Modi’s statement that India needed to align its patent laws with international standards • World-wide, there is no correlation btw an IPR & FDI • The industry particularly wants the govt not to introduce data exclusivity, which bars Indian Food & Drug Administration (FDA) from approving a competitor’s product as long as exclusivity on the data lasts even for off - patent medicines ○ Granting data exclusivity does away with the recourse to pre-grant oppositions & compulsory licensing ○ Being a major producer of generic drugs, it would also hinder bulk procurers like MSF (Doctors Without Borders) & bring into question the future of the public procurement programmes Accepting it would lead to monopolies on patented & non-patented products through a regulatory process

○ Accepting it would lead to monopolies on patented & non-patented products through a regulatory process ○ The TRIPS Agreement requires protection of data, not data exclusivity, which in the present context is synonymous with market exclusivity

06-05-2015 • Indian courts have invoked the common law of trade secrecy & breach of confidence to protect trade secrets when appropriate

07-05-2015 The Indian Patents Act 2005 provides for a high standard of patentability, allows for compulsory licensing provisions & pre- & post-grant objection to patents • The progressive Act has been invoked in several judgments recently in relation to pharmaceutical patents — for eg. the Supreme Court upheld the sale of a generic version of the cancer drug Nexavar in Dec 2014, & upheld the Indian patent office’s rejection of Novartis’s application for a patent for its anti-cancer drug, Glivec • It must be mentioned that patent laws in India are compliant with the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) • The restrictive patenting laws have protected a thriving generic pharmaceutical industry producing low-cost drugs in India. The industry has gradually become export-driven, resulting in these companies becoming keen to tie up with major pharmaceutical companies abroad by seeking voluntary licensing arrangements • Other countries have also looked at India’s Patents Act as a model, with affordability of pharma products & drugs being a key concern

18-05-2015 • The Indian Patents Act, 1970 was amended in 2005 to bring its laws in line with the agreement on TRIPS ○ The most important of those amendments related to the introduction of product patents for 20 years, including for pharmaceutical products ○ Significant safeguards were built into the legislation. These included debarring of ever greening patents, a process by which the patent holder seeks to extend the life of patents by some minor tinkering with the products ○ The amended legislation also expanded the scope of compulsory licensing & introduced for the first time post grant opposition to patents (Provisions relating to pre-grant opposition were retained) ○ The legislation raised the bar for what constitutes an invention & what cannot be patented in India • The above provisions served Indian consumers well by keeping the price of some important drugs dealing with critical illnesses such as cancer under check • The Patent office’s rulings have by & large been upheld by the highest courts • Inevitably big pharma have lobbied with their govts to force India to dilute the provisions • The Office of the USTR is part of the executive office of the US President & apart from being the chief trade negotiator of the US govt, has enormous clout over the conduct of trade across the world ○ On April 30, 2015, the office of the USTR named India & China among 13 countries, which were placed on a priority list, requiring close scrutiny for their alleged IPR weaknesses in diverse areas including pharma, IT & publishing ○ India while being on the priority list was not designated a priority watch country, which might have led to penal action against India • The govt has done well to release a draft IPR policy in the public domain ○ Taking a balanced approach, it says that existing laws — that seek to protect the rights & incentives of innovators on the one hand & public interest on the other — would remain ○ However it also calls for legislative changes to keep pace with economic & technological developments • IPR challenges have to be met increasingly through political action & diplomacy. The govt needs to strengthen its decision-making process & boost the skills of its negotiators ○ An important initiative of the NDA govt has been the setting up of an IPR think tank which among other tasks, will help in the formulation of a National Intellectual Property Rights policy • India does not have an IPR policy but it has a strong legal foundation ○ Important precedents have been set especially in pharma-related matters ○ Besides, there is a well functioning Patents office with sufficient experience to grant patents & uphold consumer interests. From here a new, well balanced policy should not be too difficult

07-06-2015 • India’s IPR remains a contentious issue with the USTR questioning the country’s patent regime ○ The USTR had last year initiated a unilateral probe into the country’s patent laws following concerns raised by lobby groups ○ The Special 301 report 2015 of the US ranked India under the priority watch list ○ Following the concerns raised, the govt in 2014 announced that a national IPR policy would be framed to safeguard India’s interest

05-11-2015 • India has been able to use all the flexibilities under TRIPS to deliver affordable generic drugs ○ Thanks to India, > 10.5 million African lives have been saved

Neutrinos 12 February 2015 11:06

Long Baseline Neutrino Experiment (LBNE)

24-02-2014

US researchers have given details of a plan for one of the biggest physics experiments ever built. Scientists at Fermilab, just outside Chicago, want to fire a beam of particles called neutrinos through 1,300km (800 miles) of rock some 30km below the surface. The experiment's aim is to learn more about how the Universe was created. It is a $1.5bn (£1bn) US project. Those involved describe it as the most important experiment since the search for the . It is the next big thing in particle physics. "It is as big as the search for the Higgs and will revolutionise our understanding of physics." Neutrino Particle

• Second most abundant particle in the Universe, after photons of light • Means "small neutral one" in Italian; was first proposed by Wolfgang Pauli in 1930 • Uncharged, and created in nuclear reactions and some radioactive decay chains • Shown to have a tiny mass, but hardly interacts with other particles of matter • Comes in three flavours, or types, referred to as , tau and electron • These flavours are able to oscillate - flip from one type to another - during flight • Could be a Majorana particle - that is a particle that is equal to its anti-particle Flavour flip Neutrinos are ghostly particles that permeate the Universe. They hardly interact with our world, tending to pass right through the Earth. But 16 years ago, Japanese researchers discovered that these ephemeral flecks did indeed have mass, and not only that - they changed from one form, or flavour, to another as they travelled. This solved a puzzling observation made by US researchers in a South Dakota mine decades earlier. They found that they were not detecting as many neutrinos coming from the Sun as they were expecting. The Japanese result suggested that some of them had changed into another type of neutrino on their way to Earth. This discovery cannot be explained by the current theory of sub-atomic physics. So some physicists believe that by finding out how these neutrinos change flavour and determining their exact mass will give a deeper understanding of how the Universe works and specifically how it came into being Matter trick Current theories of creation suggest that shortly after the Big Bang, there were equal amounts of matter (from which our Universe is made) and anti-matter. If that were the case, the two would have cancelled each other out - and yet here we are. Some believe that contained within the neutrino's oscillation is the cosmic sleight-of-hand - called CP violation in the jargon - that enabled some matter to survive after the Big Bang. "Neutrinos tell us something about the origins of the Universe," said Prof Soldner-Rembold. "We know there is more matter than anti-matter in the Universe, and that is why we are all here. "But we don't really understand why, and neutrinos might provide a key to why there is more matter than anti-matter and ultimately why we are here." It is more likely for neutrinos to change from one type to another if they pass through rock.

Science Page 67 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive and ultimately why we are here." It is more likely for neutrinos to change from one type to another if they pass through rock. So, in order to maximise the chances of seeing this rare event, Fermilab plans to create a beam that will send trillions of neutrinos every second through 1,300km of rock from Illinois to a giant detector in South Dakota. The beam itself will start 1.5km under the surface, and at its greatest depth will be some 30km down.

The construction of the project is expected to be completed in 10 years' time. Such experiments do not come cheap, and Fermilab's plan is one of three big experiments that have been proposed to study neutrinos. The others are a European initiative led by Cern, and one suggested by the Japanese. How many of these experiments can be funded by the international community is unclear, and the three proposals have been involved in a very high-stakes game of poker to determine which experiment will get the nod.

Some argue that the European and Japanese experiments are better in their own way. But there is also an argument that the Americans deserve this one. Europe already has the Large Hadron Collider at Cern, and siting the neutrino lab in the US means it too would have a particle physics flagship.

So, having secured congressional backing for the LBNE project this year, it may be that the Americans now hold the strongest hand, especially with India, Italy and now the UK lining up behind Fermilab

12-02-2015 No damage with artificially produced neutrinos • China, using neutrinos (artificial) from their Daya Bay nuclear reactor has measured one of the parameters associated with “neutrino oscillations” • The US is developing an experiment called the Long Baseline Neutrino Facility to beam neutrinos from Fermilab to Homestake mines (in the US) in which scientists from various countries including India are participating • neutrinos may even play a role in maintaining peace. They can be used to monitor nuclear reactors to check if anyone is making away with stores of plutonium which can be used in making nuclear weapons. This is a part of ongoing research in France

INO 31 March 2014 07:03

India-based Neutrino Observatory (INO)

• A neutrino observatory needs to be very big & must ensure low radioactivity underground with utmost attention to a clean environment

• The India-based Neutrino Observatory (INO) Project is a multi-institutional effort supported by Govt of India aimed at building a world-class underground laboratory with a rock cover of approx.1200 m for non-accelerator based high energy & nuclear physics research in India • It is India's ambitious and largest ever Rs 1,500 crore science research project to study atmospheric neutrinos • The project includes (a) construction of an underground laboratory and associated surface facilities at Pottipuram in Bodi West hills of Theni District of Tamil Nadu, (b) construction of a Iron Calirometer (ICAL) detector for studying neutrinos (c) setting up of National Centre for High Energy Physics at Madurai, for the operation and maintenance of the underground laboratory • Neutrinos are tiny, neutral particles that travel at the speed of light and interact with matter so weakly that trillions of these particles zip right through our body every second without stopping. • Detecting neutrinos – whether produced by cosmic rays striking nuclei in the atmosphere or by nuclear fusion in the Sun’s core – therefore requires massive detectors to increase the chances of spotting these fleeting particles as they plough their way through the Earth. • Neutrino detectors are thus usually located deep underground in locations that allow the rock above to absorb the copious amounts of cosmic rays that would otherwise blanket the signal. • ICAL has two features that makes it different 1. One is that it will be able to distinguish between atmospheric neutrinos and antineutrinos because when they interact with the detector material, they produce particles with opposite charges that are bent in different directions by the iron magnet. 2. ICAL will be able to measure both the energy and direction of these particles. • INO shall shed light on the mass of neutrinos, understanding neutrino oscillation which could point to why there is so much more matter than antimatter in the universe. • One important benefit of INO is that it has led to training a new generation of researchers in the art and science of neutrino detection through PhD program

31-03-2014 An elusive detector for an elusive particle The delay of a go-ahead from the Cabinet for an indigenously designed neutrino detector is demoralising for scientists because it could turn investors away

Science Page 69 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

In the late 1990s, a group of Indian physicists pitched the idea of building a neutrino observatory in the country. The product of that vision is the India-based Neutrino Observatory (INO) slated to come up near Theni district in Tamil Nadu, by 2020. According to the 12th Five Year Plan report released in October 2011, it will be built at a cost of Rs.1,323.77 crore, borne by the Departments of Atomic Energy (DAE) and Science & Technology (DST).

By 2012, these government agencies, with the help of 26 participating institutions, were able to obtain environmental clearance, and approvals from the Planning Commission and the Atomic Energy Commission. Any substantial flow of capital will happen only with Cabinet approval, which has still not been given after more than a year.

If this delay persists, the Indian scientific community will face greater difficulty in securing future projects involving foreign collaborators because we can’t deliver on time. Worse still, bright Indian minds that have ideas to test will prioritise foreign research labs over local facilities.

‘Big science’ is international This month, the delay acquired greater urgency. On March 24, the Institute of High Energy Physics, Beijing, announced that it was starting construction on China’s second major neutrino research laboratory — the Jiangmen Underground Neutrino Observatory (JUNO), to be completed at a cost of $350 million (Rs. 2,100 crore) by 2020.

Apart from the dates of completion, what Indian physicists find more troubling is that, once ready, both INO and JUNO will pursue a common goal in fundamental physics. Should China face fewer roadblocks than India does, our neighbour could even beat us to some seminal discovery. This is not a jingoistic concern for a number of reasons.

All “big science” conducted today is international in nature. The world’s largest scientific experiments involve participants from scores of institutions around the world and hundreds of scientists and engineers. In this paradigm, it is important for countries to demonstrate to potential investors that they’re capable of delivering good results on time and sustainably. The same paradigm also allows investing institutions to choose whom to support.

India is a country with prior experience in experimental neutrino physics. Neutrinos are extremely elusive fundamental particles whose many unmeasured properties hold clues about why the universe is the way it is.

In the 1960s, a neutrino observatory located at the Kolar Gold Fields in Karnataka became one of the world’s first experiments to observe neutrinos in the Earth’s atmosphere, produced as a by-product of cosmic rays colliding with its upper strata. However, the laboratory was shut in the 1990s because the mines were being closed.

However, Japanese physicist Masatoshi Koshiba and collaborators built on this observation with a larger neutrino detector in Japan, and went on to make a discovery that (jointly) won him the Nobel Prize for Physics in 2002. If Indian physicists had been able to keep the Kolar mines open, by now we could have been on par with Japan, which hosts the world-renowned Super-Kamiokande neutrino observatory involving more than 900 engineers.

Importance of time, credibility

Science Page 70 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Importance of time, credibility In 1998, physicists from the Institute of Mathematical Sciences (IMSc), Chennai, were examining a mathematical parameter of neutrinos called theta-13. As far as we know, neutrinos come in three types, and spontaneously switch from one type to another (Koshiba’s discovery).

The frequency with which they engage in this process is influenced by their masses and sources, and theta-13 is an angle that determines the nature of this connection. The IMSc team calculated that it could at most measure 12°. In 2012, the Daya Bay neutrino experiment in China found that it was 8-9°, reaffirming the IMSc results and drawing attention from physicists because the value is particularly high. In fact, INO will leverage this “largeness” to investigate the masses of the three types of neutrinos relative to each other.

So, while the Indian scientific community is ready to work with an indigenously designed detector, the delay of a go- ahead from the Cabinet becomes demoralising because we automatically lose time and access to resources from potential investors.

“This is why we’re calling it an India-based observatory, not an Indian observatory, because we seek foreign collaborators in terms of investment and expertise,” says G. Rajasekaran, former joint director of IMSc, who is involved in the INO project.

On the other hand, China appears to have been both prescient and focussed on its goals. It purchased companies manufacturing the necessary components in the last five years, developed the detector technology in the last 24 months, and was confident enough to announce completion in barely six years. Thanks to its Daya Bay experiment holding it in good stead, JUNO is poised to be an international collaboration, too. Institutions from France, Germany, Italy, the U.S. and Russia have evinced interest in it.

Beyond money, there is also a question of credibility. Once Cabinet approval for INO comes through, it is estimated that digging the vast underground cavern to contain the principal neutrino detector will take five years, and the assembly of components, another year more. We ought to start now to be ready in 2020.

Because neutrinos are such elusive particles, any experiments on them will yield correspondingly “unsure” results that will necessitate corroboration by other experiments. In this context, JUNO and INO could complement each other. Similarly, if INO is delayed, JUNO is going to look for confirmation from experiments in Japan, South Korea and the U.S.

It is notable that the INO laboratory’s design permits it to also host a dark-matter decay experiment, in essence accommodating areas of research that are demanding great attention today. But if what can only be called an undue delay on the government’s part continues, we will again miss the bus.

06-01-2015 Cabinet clears INO project • It is projected as the largest basic sciences project in India • The project will be set up near Pottipuram village in the Bodi West Hills of Theni district, Tamil Nadu • This project aims at building a world-class underground laboratory primarily to study neutrinos • Determination of neutrino masses & mixing parameters is the most significant open problem in particle physics today & is the key goal of INO project • The underground facility will develop into a full-fledged science laboratory for other studies as well in physics, biology, geology, all of which will exploit the special conditions existing in deep underground • In addition, an Inter-In- stitutional Centre for High Energy Physics will be estab- lished at Madurai, about 110 km from the proposed INO site for operationalising the underground laboratory, for detector R&D & human resource development • The govt has also approved the construction of a 50 kilo ton magnetised Iron Calorimeter detector to study properties of neutrinos & to address the issue of neutrino mass hierarchy • An important outcome of the project will be training young researchers in large- scale experimental science, including detector instrumentation technology, an area which needs strong development in the country

• A pioneer in the field of neutrino science, India was a world leader in 1965 • In the mid-1990s, with the closing of Kolar Gold Fields which was the site of the experiments, experimental neutrino research in India came to a halt, & the INO is expected to revive the lost advantage • The 3 types of neutrinos, which were initially thought to be massless, are now believed to have a small mass • This was shown by observations of neutrino oscillation, which is a phenomenon by which one type of neutrino transforms into another • There is a hierarchy among the masses of these 3 types of neutrino & the experiments at the INO will study this mass ordering using a magnetised iron calorimeter (ICAL) • The ICAL is a massive detector which will be made of iron (50,000 tonnes) • The project will be housed in the Bodi West Hills about 100 km from Madurai, Tamil Nadu • the need for such a massive detector & for drilling underground is that the neutrinos interact very weakly with the surroundings (neutrinos just pass through objects without leaving a trace). Since they interact so weakly, detecting them over other interactions is impossible • We need to have a barrier of at least 1 km of earth to block out other radiation & particles, such as from cosmic rays (hence going underground) • They will construct a tunnel at a depth of 1,300 metres below the peak, which is 2 km X 7.5m X 7.5m. This will lead to a chamber that will house the detector

• 50,000 tonnes of magnets will make up the iron calorimeter detector • 23 institutions are part of the project as of now. Over a 100 physicists & engineers are part of it • The INO project is expected to be ready by 2020 • This underground facility will develop into a full- fledged laboratory for many kinds of studies in physics, biology, geology & other disciplines & would become a huge scientific asset for basic science research • Spin-off benefits: Detector technologies have implications for development of other equipment such as medical imaging (internet developed as a spin-off technology at CERN) India & neutrinos • An underground laboratory for the study of neutrinos was created in 1951 in the gold mines of Kolar in Karnataka, but it shut down when the mines closed in 1992 • In fact, this laboratory was the first one to establish that the interaction of cosmic rays with the atmosphere also generated neutrinos • Such neutrinos were detected in this laboratory in 1965 & it was the first concrete proof of what was until then only a theory Comments • Coz most of the neutrinos belong to the Big Bang age & have remained unchanged ever since due to their weak interactive nature, scientists believe they can reveal some information about the way the universe started & the manner it changed over time

17-06-2015 • In the 1960s, India led neutrino research using a gold mine at Kolar in Karnataka called the Kolar Gold Field Lab (1965). It enabled researchers to detect atmospheric neutrinos. In 1992, when the mine became uneconomical, the laboratory was shut down ○ The Magnetized Iron Calorimeter (ICAL) being set up at INO will be among the largest ever in the world, weighing over 50,000 tonnes • Neutrinos, first proposed by Swiss scientist Wolfgang Pauli in 1930, are the 2nd most widely occurring particle in the universe (1st is photons) ○ In fact, neutrinos are so abundant that there are > 100 trillion of them passing right through each of us every second . This is the reason why INO needs to be built deep into the earth — 1,300 metres into the earth . At this depth, it would be able to keep itself away from all the trillions of neutrinos produced in the atmosphere ○ Neutrinos have been in the universe literally since forever, being almost 14 billion years old — as much as the universe itself ○ Neutrinos occur in 3 different types, or flavours: v{-e}, vμ & vτ . These are separated in terms of different masses . Neutrinos have a tiny mass, but the ordering of the neutrino mass states is not known & is one of the key questions that remain unanswered till today. This is a major challenge INO will set to resolve ○ Neutrinos are the least harmful of all elementary particles, as they almost never react with solid bodies . The mean free path for iron, or the average distance a neutrino will travel in say an iron rod, before interacting with an atom, is about 1 light year Potential uses • Neutrinos hide within them a vast pool of knowledge & could open up new vistas in the fields of astronomy & astrophysics, communication & even in medical imaging • Neutrinos may have a role to play in nuclear non-proliferation through the remote monitoring of nuclear reactors ○ The plutonium-239 which is made via nuclear transmutation in the reactor from uranium-238 can potentially be used in nuclear devices by terrorist groups ○ Using appropriate neutrino detectors, the plutonium content can be monitored remotely & used to detect any pilferage • Understanding neutrinos can help us detect mineral & oil deposits deep in the earth ○ Neutrinos tend to change their “flavour” depending on how far they have travelled & how much matter they have passed through in the way ○ This property might help us detect early geological defects deep within the earth, & thereby might be our answer to an early warning system against earthquakes ○ Geoneutrinos First found in 2005, they are produced by the radioactive decay of uranium, thorium & potassium in the

. First found in 2005, they are produced by the radioactive decay of uranium, thorium & potassium in the Earth’s crust & just below it . Rapid analysis of these Geoneutrinos by neutrino monitoring stations — a process called Neutrino Tomography — could provide us vital seismological data which can detect early disturbances & vibrations produced by earthquakes • Data transmission ○ Neutrinos can pass right through the earth. They may open up a faster way to send data than the current ‘around the earth’ model, using towers, cables or satellites ○ Such a communication system using neutrinos will be free of transmission losses as neutrinos rarely react with the atoms in their path • Some scientists further believe that if there is any extraterrestrial form of life, neutrinos will also be the fastest & most trusted way to communicate with them • Neutrinos are the information bearers of the universe — which are almost never lost in their path. Studying neutrinos at INO may help us unravel the deepest mystery of the universe — why there is more matter than antimatter in the universe • Some scientists believe that formidable neutrino research can help us understand dark matter ○ Dark matter & dark energy make up 95% of the universe, far more predominant than ordinary matter in the universe — but we hardly understand it

Standard Model of Physics 18 February 2014 20:32

27-03-2014 • the currently highly successful of elementary particles, bolstered by the discovery of the Higgs particle in 2012

"Theory of everything" - the Standard Model The existence of the Higgs mechanism, it was shown to be central to the Standard Model, the dominant "big theory" in physics, & our best understanding of how the Universe works.

Large Hadron Collider (LHC)

20-11-2014 CERN scientists discover 2 new subatomic particles • SCIENTISTS at the world's largest smasher have discovered two new sub- atomic particles never seen before that could widen our understanding of the universe. • An experiment using the European Organization for Nuclear Research's (CERN) Large Hadron Collider found the new particles, which were predicted to exist, and are both made from three bound together by a strong force • It could shed more light on how things work beyond the "Standard Model" physics theory explaining the basic building blocks of matter

LHC & (Susy)

06-01-2015 • LHC will start its operations again in 2015 • The LHC's main job is to track down phenomenon called Susy • This is the nickname physicists have given to the concept of supersymmetry • Supersymmetry lies at the heart of most models of new physics • Susy, dreamed up in 1981 to answer tough questions about existing physical models, has been playing hide & seek since then as first the Americans, using the now-closed Tevatron accelerator at Fermilab, near Chicago & then the Europeans, using the LHC at CERN, a laboratory in Geneva, have sought signs of her existence Susy exists to resolve a conundrum • In the 2nd half of the 20th century physicists painstakingly assembled what has come to be called the Standard Model ○ This explains all known fundamental particles & forces except for gravity, which has its own private model called general relativity ○ But, though the Standard Model works, it depends on many arbitrary mathematical assumptions ○ The conundrum is why these assumptions have the values they do. But the need for a lot of those assumptions would disappear if the known particles had heavier partner particles: their super- symmetric twins ○ There are various versions of super- symmetry, but all of the most plausible predict that some of these partner particles, though heavier than the particles of the Standard Model, & thus harder to make in accelerators, are nevertheless sufficiently light that either they should have been found already, or else they should show up pretty quickly when the LHC is turned back on • The LHC's upgrade is therefore the last attempt for Standard Model theory, at least in its conventional form ○ Failing to find supersymmetry would be tricky not only for those who hope to use it to clarify the Standard Model, but also for those others who think Susy will explain the nature of so-called dark matter — which its gravitational effects show is 6 times as abundant in the universe as the familiar matter ○ Many physicists are betting that dark matter is composed of one or more types of supersymmetric partner parti- cles

09-03-2015 • The Large Hadron Collider will start its operations in March 2015 which has already identified Higgs Boson Higgs Boson is a mysterious entity from the 1st trillionth of a second of creation

○ Higgs Boson is a mysterious entity from the 1st trillionth of a second of creation • Physicists call their blueprint of creation "the standard model" ○ It predicted the Higgs Boson, & it links the nuclear & electromagnetic forces, & the particles & waves from which planets, stars, galaxies & people are all composed ○ But there are misgivings & uncertainties like the dark matter & dark energy which account for the other 96% of all matter-energy in the universe ○ LHC will now probe this

08-04-2015 • Supersymmetry was conceived in the 1980s to account for certain blurs in the standard model of physics, which explains all particles & forces of the universe except gravity • Gravity has its own theory — that of general relativity • The blurs are beautifully smoothed over with the assumption that every particle in the sensible universe is mirrored by a much heavier particle that cannot be sensed, whose presence is inferred only by its gravitational effect

String theory for elementary particles

02-07-2015 • 20th century physics consisted of 2 great theories — quantum mechanics, which describes atoms, molecules, & subatomic particles, & Einstein's theory of gravity (which he called General Relativity), which we use to understand stars, galaxies, & the universe as a whole. ○ These two theories are in conflict with each other ○ Since stars (for eg) are ultimately made of atoms & subatomic particles, it does not make sense to have one theory for the stars & one theory for the subatomic particles • String theory is the framework in which physicists have succeeded in reconciling Einstein's theory of gravity with quantum mechanics ○ There are many circumstantial indications that string theory is on the right track ○ The success of string theory in reconciling gravity with quantum mechanics is the main reason that people are interested in it • One important facet of string theory is supersymmetry

Higgs Boson 18 February 2014 20:33

• The Higgs mechanism explains why particles have mass. It predicts the existence of a particle, the Higgs boson, which was finally detected at Cern in 2012, after a 50-year effort

09-09-2014 ‘God particle’ could destroy the universe, warns Hawking According to Prof. Hawking, 72, at very high energy levels the Higgs boson, which gives shape and size to everything that exists, could become unstable. This, he said, could cause a “catastrophic vacuum decay” that would lead space and time to collapse.

11-09-2014 God particle or the very devil? Theoretical calculations indicate that the universe is in a meta-stable state, close to the edge of a zone of stability ’s declaration that the “God particle” has the potential to destroy the universe is now trending amidst eager readers. Can this really happen and how does one understand this statement?

Gian Giudice, member of the CERN group for theoretical physics and author of A Zeptospace Odyssey, explains this beautifully in a TED talk entitled “Why our universe might exist on a knife edge.”

The story begins with the early universe. According to theories of the cosmos, about one-tenth of a billionth of a second after the big bang, spacetime underwent a phase transition and space became filled with the Higgs field.

Interacting with this field causes particles to gain energy which manifests as the mass of the particle.

The Higgs field itself can exist in two states — just as water can exist as ice or liquid water.

One of these states of the Higgs field is the normal state as we experience it. The other is a state which is many, many times denser than this.

The existence of this other phase is a potential problem, because when there exist two such states of an entity, there could be a transition from one to the other even if there is an energy barrier, which has to be crossed if such a transition should occur. The energy barrier thus prevents such a transition. This can happen by a process known as quantum tunnelling.

Quantum mechanics allows particles on one side of a barrier, for instance a wall, to “tunnel” through to the other side.

In the case of the universe and the Higgs field, we are talking about the potential barrier between the two states of the Higgs field, one of which is the local ground state which the Higgs now occupies and the other, the lower-energy vacuum where it would exist in the denser state, completely ruled by different laws of physics.

A group with Dario Buttazzo of CERN, theory group, as first author of a paper in the Journal of High Energy Physics published last year had calculated the vacuum stability of the Universe.

Butazzo and others in the team discuss how the vacuum stability of the Universe depends on two parameters — the masses of the Higgs boson and the Top .

Given that the mass of the Higgs boson has been determined to be 125 GeV by experiments in the Large Hadron Collider, they identify that the universe is in a meta-stable state, close to the edge of a zone of stability.

This state can remain stable for a long time to come — even long past the time when the sun would grow to be a red giant and swallow up the earth.

Prof. Giudice, in the TED talk, compares the stability of the universe to that of sand dunes in deserts.

Studying the shape of the dunes would reveal that they too are poised on the brink of collapse.

To draw another analogy from physics, there is a small probability that all the molecules of air in a room can collect at one corner leaving the rest of the room empty.

But it does not happen as the probability is incredibly low.

These are reasons why the tunneling and collapse of the universe has not happened for 13 billion years it has existed, and the likelihood that it will happen anytime soon is very small. Giudice’s calculations put the timescale of such an event at 10100 years which is certainly long!

There is also the question of new physics: the whole argument assumes that the physics of the standard model would persist up to energy scales of 100 billion GeV. Shrihari Gopalakrishna, a particle physicist at Institute of Mathematical Sciences, Chennai, says, “The Large Hadron Collider has tested physics up to about a few 100 GeV energy scale, and has found the Higgs boson at a mass of about 125 GeV. With this new piece of information, many groups of theorists asked whether the Universe is in a stable, meta-stable or unstable vacuum state.

They reach the very intriguing conclusion that we are most likely living at the edge of stability in a meta-stable vacuum.

One should keep in mind that such conclusions are based on extrapolating to very high energies using known physics, namely, the standard model, and if new physics is present, then these conclusions may no longer be valid.”

06-03-2014 Xylem-based water filters In India, more than one in ten households still lack sufficient drinking water, according to the 69th round of the National Sample Survey.

While expensive alternatives to filter water exist, the search for a simple, cost-effective technique continues. Researchers from MIT have been able to filter water using plant xylem. In tests conducted with deionised water in which bacteria and dye were introduced, the xylem filter effectively removed both when subjected to pressure. Xylem is a transport tissue in vascular plants that conducts water and dissolved nutrients upwards from the roots. Tracheids, which are cells in the xylem, are shorter and have smaller diameters in conifers, thereby offering higher resistance to flow but a greater cross-sectional area of the stem to conducting xylem tissue. This likely makes it the most suitable xylem tissues for filtration at the micron or larger scale. This filter should work with real-world water samples as long as it is not highly turbid. Turbidity tends to clog filters, and this one is not an exception The researchers prepared the xylem filter by removing the bark of pine tree branches and then inserting it into a tube. The pressure that was used for this study suggests that it is easily achievable using a gravitational pressure head. A cheap disposable xylem filter might just be the solution to availability of safe drinking water. It is important to note that these filters are still in their nascent stages. Identifying locally available sources of xylem, testing the flow through xylem of different plants, improving the rejection of viruses up to nanoparticles are some of the challenges that lay ahead.

Researched on the unexplored world of animal poisons, looking for that missing miracle cure for some of the most dreaded human diseases of the nervous system

29-05-2014 After genome, the proteome: Bangalore lab maps human protein Breakthrough could transform understanding of disease — and cure.

Harsh Gowda In what is being called a medical breakthrough study that could change the way in which cancers and heart problems are diagnosed and treated, researchers from the Institute of Bioinformatics (IOB), Bangalore, as part of a 72-member team, have for the first time deciphered a near complete protein map of human beings. While the Johns Hopkins University, Baltimore, is the lead American partner, 46 researchers are Indians. The finding, to

While the Johns Hopkins University, Baltimore, is the lead American partner, 46 researchers are Indians. The finding, to be published on Thursday in leading British journal Nature as a cover feature titled “A Draft Map of the Human Proteome”, could offer deeper insight into why humans suffer from diabetes, cancer and cardiac problems among other diseases. Explaining the study, lead researcher Akhilesh Pandey, who hails from Kanpur and is currently a professor at the Johns Hopkins University and founder director of IOB, Bangalore, said, “One can think of the human body as a huge library where each protein is a book. The difficulty is that we don’t have a comprehensive catalogue that gives us the titles of the available books and where to find them. We think we now have a good first draft of that comprehensive catalogue.” This is the next big thing that genetic researchers have been waiting for after the human genome project. While researchers had felt that mere sequencing of the genes would unlock the mystery of life, the true potential of the human genome mapping could not be realised. Scientists hit a roadblock as not enough was known about the proteins that translate the genetic information into functional units like enzymes and proteins. Most human diseases and aging happen because proteins and enzymes become dysfunctional —nobody fully understands why. “Although India did not participate in the human genome project, completion of a human proteome map by this team now puts India at the forefront of the international efforts to characterise the human proteome. This should be truly a matter for pride for science and scientists working in India,” said Pandey. “While DNA preserves the code of life and the human genome project deciphered that, a similar estimate for proteins, which determine the outcome of life, was not available. The human proteome map is a major step in that direction,” said Shahid Jameel, a well-known molecular biologist and head of Wellcome Trust, Department of Biotechnology, India Alliance that provided Rs 1.5 crore over two years for the project. The team analysed 30 different tissue samples from adults and foetuses to arrive at the map of proteins coded by 17,294 different genes. “We identified more than 2,000 proteins that were labelled as ‘missing proteins’ by the international research community as they had never been detected or measured. A remarkable achievement is the identification of almost 200 novel proteins in humans that had not been discovered,” said Harsh Gowda of IOB. “The group has built a publicly available interactive database for analysis of their data sets which could be an important resource for biological research and medical diagnosis,” said the report in Nature. Prof K Vijay Raghavan, Secretary, Department of Biotechnology, said the research “links proteins directly to diseases”. He said this would help in in targeted drug discovery as it gives a “peek into the dynamics of how a human cell works”.

29-05-2014 Scientists map proteins produced in human body Thirteen years after the human genome was sequenced, two research groups have independently mapped the extent to which cells in various organs in the body turn many thousands of genes into proteins. From bacteria to humans, genes are made up of units of DNA, called base pairs. The sequence of base pairs in genes tell a cell's molecular machinery what proteins to produce. Ultimately, it is the proteins that carry out a myriad processes essential for life. Once the over three billion base pairs that make up the human genome were sequenced, analysis of that data indicated that there are about 20,000 protein-coding genes. In a paper just published in Nature, an international team of scientists led by Akhilesh Pandey of the Johns Hopkins University in the U.S and Harsha Gowda at the Institute of Bioinformatics in Bangalore has drawn up a draft map of proteins produced from 17,294 genes. There was evidence for proteins coming from 18,097 human genes, reported Bernhard Kuster of Technische Universitaet Muenchen in Germany and his colleagues in a separate paper published in the same issue of the journal. The two papers marked a “major advance”, providing comprehensive data about proteins expressed in different human tissues. Dr. Pandey and his colleagues examined proteins produced by normal cells in 30 tissue samples, adult and foetal as well as those found in blood. They found 'housekeeping proteins' from 2,350 genes that were produced in all tissues. On the other hand, proteins from 1,537 genes turned up in only one of the tissues. A number of proteins were expressed only during foetal development. “The driving impetus for our work was to develop a reference of what is normal for human organs and cells,” said Dr. Pandey in an email. This information could provide clues to biologists seeking to elucidate the function of individual proteins. In addition, knowledge about organ-specific proteins could be used for detection of diseases arising in those organs. “The day may not be too far when people have their protein profiles mapped, much like [personal] genome sequencing

“The day may not be too far when people have their protein profiles mapped, much like [personal] genome sequencing we have today. This could help us diagnose more diseases and diagnose diseases better too,” Although proteins from about 84 per cent of all human genes had been found, those from the remaining genes may have eluded detection, remarked experts. This could have occurred if the proteins were expressed in tissues or organs that had not been sampled. Alternatively, they might be expressed at very low levels, requiring special techniques to track down

Turing’s on morphogenesis

03-04-2014 Turing’s thesis on morphogenesis validated Ever wondered what causes the variety of patterns we see in nature — a zebra’s stripes, the leopard’s spots or the alternating arrangement of leaves on a plant’s branches? How do cells which are identical to start with, differentiate and form regular patterns? There indeed is a scientific explanation for it, and it has been now validated by experiments, too.

In their paper, recently published in the Proceedings of National Academy of Sciences, Nathan Tompkins and others describe an experiment involving a reaction-diffusion system which evolves patterns that can lead to cell differentiation.

Theoretically this was worked out nearly 60 years ago —Alan Turing came up with an explanation for the origin of static patterns in nature in 1952. In a seminal paper he outlined that chemicals diffusing across identical cells and interacting with each other would result in the cells developing differences in chemical concentrations and this would lead to their getting differentiated further. For instance, when sugar is dissolved in water, it spreads evenly through the water until every cell has equal concentration of sugar.

But if there are two species of chemicals diffusing through, an activator and inhibitor, for instance, what would happen is quite different. Let us say, this happens in a linear array of cells. There would, after some time, be a different quantity of each species of chemical in the different cells. This would be further complicated if the chemicals interacted with each other.

Using differential equations to describe this reaction-diffusion process, Turing predicted that after some time, there could emerge six patterns, some of which he identified with existing patterns in biology. To prove this, Dr. Tompkins model this process in the lab and show that their experimental system replicates five of these patterns and a further throws up a seventh, hitherto unpredicted pattern.

When asked how, given that they are studying small numbers of cells, they can be sure that the patterns they are seeing are indeed genuinely periodic patterns, Seth Fraden, Department of Physics, Brandeis University, a member of the collaboration, says in an email: “We use small numbers of drops in rings, but we also used long linear arrays in the order of 100 drops and even larger hexagonal, two-dimensional arrays of the order of 10,000 drops… We believe the patterns are genuine because they appear where the model predicts them.”

18-09-2014 New light on genetic make-up of Europeans The study revealed that the European population is a mixture of three founder groups and not two as was believed. Throwing new light on the origins of present-day Europeans, a team of international researchers has traced their roots to three ancestral groups and not two as was believed. The results of the study have been published today (September 18) in Nature.

The consortium led by researchers from the University of Tubingen and Harvard Medical School in collaboration with scientists from the Centre for Cellular and Molecular Biology (CCMB), Hyderabad, studied three different ancient human bone samples and compared them with 200 diverse contemporary populations across the world through genome-wide data of about 2,400 humans. The contemporary populations included the enigmatic tribal population of Andaman and Nicobar Islands, according to Dr. Kumaraswamy Thangaraj, one of the authors of the study and Senior Principal Scientist at CCMB.

The study analysed ancient human genomes from a more than 7,000-year-old early farmer from Stuttgart in Southern Germany, belonging to linearbandkeramik (LBK), a sedentary farming culture, a more than 8,000-year-old hunter- gatherer from the Loschbour rock shelter in Luxembourg, and seven over 8,000-year-old hunter-gatherers from Motala in Sweden.

Tremendous impact According to a CCMB release, the beginning of agriculture and animal domestication, which began in the Near East about 11,000 years ago, had a tremendous impact on human lifestyle. Hunter-gatherers were replaced in many places by farmers and there were large increases in population size that laid the foundation for larger towns and eventually complex societies.

Archaeological evidence suggests that a transition to a farming lifestyle in Central Europe occurred around 7,500 years ago with the appearance of LBK.

While the first ancestral group was indigenous hunter-gatherers; the second comprised Middle Eastern farmers that migrated to Europe around 7,500 years ago. The novel third group is a more mysterious population that spanned North Eurasia and genetically connects Europeans and Native Americans.

All three groups The researchers calculated the proportion of the ancestral components in present-day Europeans and found that all Europeans have ancestry from all three groups. While Northern Europeans have more hunter-gatherer ancestry (up to 50 per cent in Lithuanians), Southern Europeans have more farmer ancestry.

The Northern Eurasian ancestry was the smallest component and never more than 20 per cent.

Dr. Thangaraj said that a genetic mutation was introduced to digest milk-sugar in humans after they domesticated cattle and started drinking milk. Hunter-gatherers and early farmers had high copy numbers of amylase in their genomes suggesting they had already adapted to a starch-rich diet. This amylase factor was more common in Europeans, Middle Eastern people and North West Indians.

Indian emergence CCMB scientists earlier found that Indians emerged from two ancestral populations — ancestral South Indians (ASI) and ancestral North Indians (ANI). While ASI did not have any genetic affinity outside India, ANI showed up to 70 per cent genetic affinity with Europeans. “However, it would be interesting to see which one of the three ancestral European populations is related to ANI”, says Dr. Lalji Singh, formerly Director of CCMB and also a co-author of the study. Dr. Thangaraj says he suspected that the Middle Eastern component of milk-digesting gene might have contributed to ANI.

2013 Scientists ‘freeze’ light for an entire minute What it is: Scientists have trapped light, the fastest traveling thing in the universe, and held it still in a small space. Light travels at 300 million meters per second – that alone is testimony to its slippery nature, and casts in comic light any suggestion to trap it. Imagine, it can make 7,500 trips around the Earth along the equator ever second! How do you trap something like that? By simply being clever, think a bunch of German scientists, and they have a unique result to show for it. They were able to ‘freeze’ light inside a crystal for one full minute using a phenomenon called electromagnetically induced transparency (EIT). A specially chosen crystal was found to be transparent for certain frequencies of light – an occurrence called EIT. They shot a laser beam, which is a source of light, into the crystal. After some time, they turned on another laser that cut off the first one. This immediately killed the crystal’s transparency, trapping the first laser beam inside. The achievement is awesome in another context, too. Light has a property called quantum coherence. If quantum coherence is preserved, then the light beam can carry information without losing it. The German researchers found that the laser beam trapped inside for a minute retained its quantum coherence. Why it matters: Therefore, such EIT crystals can be used to store light – for longer and longer periods of time – using lasers, setting the stage for high-efficiency, high-speed data storage devices.

22-02-2014 GPS tracking system Uses

Technology Page 1 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Uses Modern navigation and tracking mechanisms through and a host of global positioning system (GPS) services are not only helping thousands of drivers navigate their way but also authorities like the Transport Department and the Delhi Integrated Multi Modal Transport System to optimise public transport services. Since the GPS tracking system started, it has provided them with a huge fillip since it ensures that drivers stick to a certain discipline under the watchful eyes of those in the control room. “The drivers know their movements are monitored and any violation, be it not leaving a depot on time, exceeding the speed limit or not stopping at a traffic signal, will lead to disciplinary action against them. The idea is that the commuters travelling in these buses should remain safe and not face any kind of inconvenience,” she said. The disciplinary action range from suspension to penalisation of the private operator, under the cluster bus scheme, for violation of the service level agreement. And it helps in other ways too. “The GPS also helps us optimise the service and thus generate more revenue. The buses plying on every route get tracked and so when two buses of the same route come close to each other, the control room informs the conductor of the rear bus to slow down.” Either the bus plying behind stops for some time or it just starts moving slowly. This ensures proper spacing and brings down waiting time for buses along the route. GPS systems are also being used by private cab service providers to give security to passengers, especially women. They feel safer travelling by such taxis since they know that the cab’s movement is being tracked at all times. GPS devices can also prevent vehicles from being stolen. Delhi is home to the maximum number of registered vehicles. Nowadays, many high-end cars come installed with secret-tracking devices. They can also be purchased separately. Some of the GPS services can also be linked to phone applications, which keep the user updated about his or her location as well as traffic volume and suggested routes. “I often get confused over the names of streets and lanes, I always rely upon these electronic maps,” said a second-year Delhi University student Srishti. Another student, Yashika Sunaria, said even if she takes a wrong route, the map shows alternative ways to help her reach her destination. However, in areas like Connaught Place where the Internet connection is not good, some of these services hardly work. Then there are services which end up misleading people, making them wonder if a technology in its infancy is really worth giving a try.

24-02-2014 TerraPower • In 2006, Bill Gates and a group of like-minded visionaries decided that the private sector needed to take action. It was believed that business interests could develop a scalable, sustainable, environmentally friendly, and cost- competitive energy source that would allow all nations to quicken their pace of economic development and reduce poverty. • TerraPower was founded to find a solution for global energy needs TerraPower aims to develop a sustainable and economic nuclear energy technology using: • Next-generation safe, affordable, clean and secure technologies • Advanced materials for more durable metallic fuels • World-class leadership for dynamic reactor engineering and innovation • Supercomputing for reliable and comprehensive modeling Travelling Wave Reactor (TWR)

• The TWR will provide a clean option for future energy technology • The TWR simplifies the necessary nuclear energy infrastructure, reducing overall costs and enabling a safe, secure form of nuclear energy. • Like any nuclear plant, the TWR will reduce the CO2 load and provide energy without increasing greenhouse gases. • The TWR will provide large amounts of sustainable base load power. For the amount of fuel used, the TWR will produce up to 50 times more power compared to today’s light water reactors. • The TWR will reduce the amount of nuclear waste produced at end-of-life. The TWR will produce a minimum of seven times less waste than today's light water reactors. With the use of sodium as coolant, the TWR will operate at a higher temperature, allowing higher thermal efficiency for electrical generation.

a higher temperature, allowing higher thermal efficiency for electrical generation. • The TWR will utilize depleted uranium as its main fuel. Just in the , more than 750,000 metric tons of depleted uranium sits useless. TWRs could convert this material into enough electricity to power all U.S. households for more than 700 years. • Like other reactors, the TWR’s unique core reaction does produce plutonium, along with other fission products, in the first “wave” of fission. However, unlike other reactors, a second “wave” follows the first, consuming much of the plutonium. Hence preventing weapons development from plutonium.

Benefits Safety: The TWR relies on the natural laws of physics to maintain the safety of the plant without operator intervention. Cost: TWR uses inexpensive depleted uranium as fuel with great efficiency, creating a cost-competitive nuclear energy technology. Environment: Compared to conventional reactors, TWRs require far less uranium mining and produce less high-level waste. Proliferation Resistance: By reducing the need for enrichment and chemical reprocessing, the TWR addresses security and proliferation concerns. Energy Security: The TWR will help a country secure a dependable supply of electricity.

10-05-2014 11th May- National Technology Day On 11th May, 1998 India achieved a major technological breakthrough by successfully carrying out nuclear tests at Pokhran. Also first, indigenous aircraft "Hansa-3" was test flown at Bangalore on this day and India also performed successful test firing of the Trishul missile on the same day. Considering above technological achievements on a particular date i.e. 11th May, the day of 11th May was chosen to be commemorated as National Technology Day

12-05-2014 Monorail Mono rail system as the name suggests, is a system which has a single rail instead of conventional system which has got two rails. But it is a misnomer. In fact, in place of rails, it has a single broad beam which supports the carriages. However, above the beam, the carriages have conventional system of two side vertical wheel as in a normal motor car. In addition, it has two horizontal guide wheels, which give lateral support to the vehicles. These horizontal wheels run abutting a vertical structural element connected to the main slab. From the outside, it appears as if the train is running on a single wheel. The propulsion system is generally electric rotary motors. The wheels have rubber tires for smooth and noise free operation. Some advance systems make use of Maglev (Magnetic Levitation) technology which uses linear Induction Motors instead of conventional rotary motors. As the train picks up speed, the entire body of the vehicle lifts up in air by a few centimetres due to magnetic force and gives a total noise free travel. The rubber-tired system is good for lower speeds up to 160 km per hour. Maglev system can give speeds up to 400 km per hour. Some systems have a hybrid of both rubber tired and Maglev. At slow speed, it uses tired system and as the speed picks up, it changes to Maglev

21-06-2014 This material can withstand 160,000 times its own weight Out of polymers, metals and ceramics, scientists have successfully developed and printed an ultra light material that can withstand 160,000 times its own weight. Using what is called additive micro-manufacturing processes, the researchers developed the micro-architected metamaterials — artificial materials with properties not found in nature — that maintain a nearly constant stiffness per unit mass density, even at ultra low density. Can be used for making aircraft components Materials with these properties have the potential to be used for developing parts and components for aircraft, automobiles and space vehicles. These lightweight materials can withstand a load of at least 160,000 times their own weight, said experts. The additive micro-manufacturing process involves using a micro-mirror display chip to create high-fidelity three dimensional (3D) parts — one layer at a time — from photosensitive feedstock materials. It allowed the team to rapidly generate materials with complex 3D micro—scale geometries that are otherwise challenging or in some cases, impossible to fabricate. “Now we can print a stiff and resilient material using a desktop machine,” said experts. The observed high stiffness was shown to be true with multiple constituent materials such as polymers, metals and ceramics. The findings appeared in the journal Science.

Bulk Metallic Glasses (BMG)

Wiki Amorphous metal An amorphous metal (also known metallic glass or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure. But unlike common glasses, such as window-glass, which are typically insulators, amorphous metals have good electrical conductivity. There are several ways in which amorphous metals can be produced, including extremely rapid cooling, physical vapor deposition, solid-state reaction, ion irradiation, and mechanical alloying.

Samples of amorphous metal, with millimeter scale

The rapid cooling, on the order of millions of degrees a second, is too fast for crystals to form and the material is "locked" in a glassy state. More recently a number of alloys with critical cooling rates low enough to allow formation of amorphous structure in thick layers (over 1 millimeter) had been produced; these are known as bulk metallic glasses (BMG). They demonstrate strengths much greater than conventional steel alloys.

Properties Amorphous alloys have a variety of potentially useful properties. In particular, they tend to be stronger than crystalline alloys of similar chemical composition. Perhaps the most useful property of bulk amorphous alloys is that they are true glasses, which means that they soften and flow upon heating. This allows for easy processing, such as by injection molding, in much the same way as polymers. As a result, amorphous alloys have been commercialized for use in sports equipment, medical devices, and as cases for electronic equipment.

Applications • Currently the most important application is due to the special magnetic properties of some ferromagnetic metallic glasses. The low magnetization loss is used in high efficiency transformers (amorphous metal transformer) at line frequency and some higher frequency transformers. Amorphous steel is a very brittle material which makes it difficult to punch into motor laminations. Also electronic article surveillance (such as theft control passive ID tags,) often uses metallic glasses because of these magnetic properties. • Amorphous metals (metallic glasses) exhibit unique softening behavior above their glass transition and this softening has been increasingly explored for thermoplastic forming of metallic glasses. It has been shown that metallic glasses can be patterned on extremely small length scales ranging from 10 nm to several millimeters. It has been suggested that this may solve the problems of nanoimprint lithography where expensive nano-molds made of silicon break easily. Nano-molds made from metallic glasses are easy to fabricate and more durable than silicon molds. • Ti40Cu36Pd14Zr10 is believed to be noncarcinogenic, is about three times stronger than titanium, and its elastic modulus nearly matches bones. It has a high wear resistance and does not produce abrasion powder. The alloy does not undergo shrinkage on solidification. A surface structure can be generated that is biologically attachable by surface modification using laser pulses, allowing better joining with bone. • Mg60Zn35Ca5, rapidly cooled to achieve amorphous structure, is being investigated as a biomaterial for

Technology Page 6 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• Mg60Zn35Ca5, rapidly cooled to achieve amorphous structure, is being investigated as a biomaterial for implantation into bones as screws, pins, or plates, to fix fractures. Unlike traditional steel or titanium, this material dissolves in organisms at a rate of roughly 1 millimeter per month and is replaced with bone tissue. This speed can be adjusted by varying the content of zinc.

14-04-2014 • Bulk metallic glasses (BMGs) is a versatile type of pliable glass that is stronger than steel • They can be used for producing hard, durable and seamless complex shapes that no other metal processing method can

Scientists at have devised a dramatically faster way of identifying and characterising complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that is stronger than steel. Using traditional methods, it usually takes a full day to identify a single metal alloy appropriate for making BMGs. The new method allows researchers to screen about 3,000 alloys per day and simultaneously ascertain certain properties, such as melting temperature and malleability.

Already used in watch components, golf clubs, and other sporting goods, BMGs also have likely applications in biomedical technology, such as implants and stents, mobile phones and other consumer electronics There are an estimated 20 million possible BMG alloys. About 120,000 metallic glasses have been produced and characterized to date Using standard methods, it would take about 4,000 years to process all possible combinations, Schroers has calculated. The new method could reduce the time to about 4 yrs Ideal BMGs offer plasticity during the manufacturing process, durability, and biocompatibility, along with affordability, Schroers emphasised in the study published in the journal Nature Materials

Thermal imaging systems

• Like GPS, thermal imaging was once used exclusively by military & law enforcement • In the early 1990s, National Guard aircraft relied on thermal sensors to look for illegal drug activity at the Branch Davidian Compound in Waco, Texas • In 2013, a Massachusetts State Police helicopter used thermal imaging to locate Boston bombing suspect • While humans see reflected light, all objects that surround us — other people, animals & even “cold” objects such as ice — give off heat, radiation beyond the visible spectrum that can be imaged in the form of a “heat signature” • A human body usually gives off more heat than the surrounding field, so it stands out • Unlike night-vision devices, which amplify small amounts of visible light, thermal imaging cameras rely on sensors known as microelectromechanical systems, or MEMS, to make images from heat • Thermal imaging cameras are made up of a large array of exotic MEMS devices, as well as specialised optics • Conventional glass & plastic lenses cannot be used because they block heat. Instead, these cameras require special lenses manufactured of transparent silicon

LC3 Cement (Limestone Calcined Clay)- Making cement less energy intensive

28-09-2014 An ongoing Indo-Swiss collaboration since 2005 is researching less energy intensive LC3 cement The research project involving the Federal Institute of Technology, Lausanne, and three Indian Institutes of Technology (IIT), Delhi, Madras and Mumbai, and Technology and Action for Rural Development (TARA) showcased the results to industries recently. The project funded by Swiss Agency for Development and Cooperation. The research will be validated by three countries involved in scientific research-India, Switzerland and Cuba. Advantages The new cement was less energy intensive by 30 per cent and had other advantages. Less energy intensive cement is a technology of the future specially when there is a scarcity of limestone, the new process allows us to use less of it. The clinker factor will be reduced and the cost of cement production will be lower and carbon emissions will be less. LC3 or Limestone Calcined Clay Cement, substitutes up to half of the carbon intensive materials and has the potential to generate 30 per cent less carbon dioxide emissions compared to traditional cement, a major reduction since cement today accounts for 5-8% of man-made emissions

Li-Fi wireless technology

06-01-2016 Dr.Tilak HR • Li-Fi (Light Fidelity) is a wireless technology that makes use of visible light in place of radio waves to transmit data at terabits/second speeds (> 100 times the speed of Wi-Fi) • It was invented by German physicist & professor Harald Haas • Though it was discovered in the last decade, proofs of concept to test commercial utilization started emerging only in 2015 • It is being tested for indoor usage & will likely be used outdoor in a big way by making use of existing infrastructure used for street & traffic lights (which are already moving towards LED lamps) • Li-Fi offers great promise to overcome the existing limitations of Wi-Fi by providing for data-heavy communication in short ranges • Since it does not pollute, it can be called a green technology for device-to-device communication in the Internet of Things (IoT) Move towards greener wireless communication • A technical solution for wireless pollution, power shortages & unavailability at outdoor locations should meet the 3L criteria: Low interference, Low power & Low maintenance • In addition, it has to support the 3Hs of High data rates, High reliability & High affordability ○ Since Li-Fi relies on visual light & not radio waves as the carrier, it has potential for the first two Hs, but the last one (high affordability) may be achieved only when volumes increase, as it has in the case of Wi-Fi • The above characteristics can be met by an all-IP (packetized) Li-Fi system utilizing existing LED lamps which are ruggedized, have a high MTBF (mean time btw failure) & consume less power, hence replacing conventional lamps on existing structures in both indoor as well as outdoor without need for any additional power supply • To make LED lamps capable of working as an access point as in Wi-Fi, a kind of media converter is required to convert the electrical data signal into photons (light), & a light detector which converts light into electricity is required on the receiving device end Potential applications • Li-Fi is still in its infancy, but some fields where it seems eminently usable are street & traffic lights ○ Traffic lights can communicate to the vehicles & with each other. Vehicles having LED-based headlights & tail lamps can communicate with each other & prevent accidents by exchanging information ○ Also, through the use of Li-Fi, traffic control can be made intelligent & real-time adaptable • Visible light being safer, they can also be used in places where radio waves can’t be used such as petrochemical & nuclear plants, aircrafts & hospitals • Li-Fi can also easily work underwater, where Wi-Fi fails completely, thereby opening opportunities for military & navigational operations • Li-Fi can be made to transmitting power wirelessly, wherein the smartphone will not only receive data through Li-Fi, but will also receive power to charge itself But, Li-Fi has some limitations

Technology Page 9 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

But, Li-Fi has some limitations • As visual light can’t pass through opaque objects & needs line of sight for communication, its range will remain very restricted to start with • Also, it is likely to face interference from external light sources, such as sunlight & bulbs, & obstructions in the path of transmission, & hence may cause interruptions in communication • Also, initially, there will be high installation costs of visual light communication systems as an add-on to lighting systems. Li-Fi receiving devices will require adapters to transmit data back to the transmitter Challenges & opportunity in India • Li-Fi can help in increasing broadband access, better traffic management ○ By converting traffic lights into LED-based access points, traffic management can be made intelligent, adaptive & real-time, & so, more efficient & effective ○ In the same way, street lights can also be converted into Li-Fi access points, making them broadband access transmitters to mobile Li-Fi enabled smartphones, converting areas into seamless hot spots • The main challenge is to create a Li-Fi ecosystem, which will need the conversion of existing smartphones into Li-Fi enabled ones by the use of a converter/adapter Conclusion • Li-Fi is not expected to completely replace Wi-Fi, but the two technologies could be used complementarily to create more efficient, green & future-proof access networks

Lanstove

• A lamp which produces high quality light and doubles up as a device to cook food without causing pollution has been invented by a team of engineers in Maharashtra. • Suitable particularly for rural households which lack clean cooking fuel and electricity, the device, aptly named Lanstove (lantern combined with cook stove), has been developed by researchers from Nimbkar Agricultural Research Institute (NARI) in Maharashtra's Phaltan. • The clean-combustion kerosene lanstove provides excellent light equivalent to that from a 200-300 W electric bulb and cooks a complete meal for a family of five just like an LPG stove. • The Lanstove consists of a nine litre pressurised kerosene cylinder, a high light output mantle lantern and a very efficient steam cooker which is based on heat pipe principle. • Millions of people in rural India cook and heat their homes using open fires and leaky stoves burning biomass (wood, animal dung and crop waste) and coal. • Nearly 2 million people die prematurely from illness like those caused by chronic obstructive respiratory disease attributable to indoor air pollution from household solid fuel use, World Health Organisation (WHO) estimates. • Carbon monoxide levels from these new lanstoves are less than 3 parts per million (ppm), whereas those from regular 'chulhas' are between 250-400 ppm or 80 to 130 times more than from the lanstove. • Thus lanstove is an extremely clean device and equivalent to LPG stove

10-09-2014 IISc develops molecular "sniffer dog" to detect explosives

The sniffer dog might finally have its day. Scientists at the Indian Institute of Science (IISc.) have created a highly sensitive fluorescent polymer that scouts out a class of commonly used explosives. TNT and other nitroaromatic compounds, which are used in a cocktail of chemicals in landmines and plastic explosive devices, release vapours that ‘quench’ the polymers, reducing their glow, according to a team from IISc. The team has developed two types of fluorescent polymers — supramolecular polymers and porous metallic-organic polymer — that are electron-rich and pick up vapour from TNT and other nitroaromatic explosives much like a molecular ‘sniffer dog’. While the drop in fluorescence is not visible to the naked eye, it is visually sensed and interpreted by a high resolution spectrometer. Nitroaromatic compounds are replacing conventional metal-based weapons in the explosives industry, the research paper says, adding that the compounds are available commercially. Besides their explosive nature, the chemicals contaminate groundwater after military operations and an efficient method to detect them at low concentrations is now needed. The next step for the teamnow is to develop similar systems to detect other forms of explosives such as RDX and ammonium nitrate

Artificial Intelligence (AI) 07 November 2014 12:16

• Artificial intelligence is any software which can mimic the way natural intelligence functions

Watson: Intelligent Supercomputer

• The principle behind Watson is called “cognitive computing” by IBM, which means that the software involved can modify itself, & thus learn as it goes along

Watson is an artificially intelligent computer system capable of answering questions posed in natural language, developed in IBM's DeepQA project by a research team led by principal investigator David Ferrucci.

The computer system was specifically developed to answer questions on the quiz show Jeopardy!. In 2011, Watson competed on Jeopardy!. Watson received the first prize of $1 million.

Cognitive systems like Watson may transform how organizations think, act, and operate in the future. Learning through interactions, they deliver evidence based responses driving better outcomes.

Hardware Watson is a question answering (QA) computing system that IBM built to apply advanced natural language processing, information retrieval, knowledge representation, automated reasoning, and machine learning technologies to the field of open domain question answering.

Watson team focused on three key capabilities: • Natural language processing • Hypothesis generation • Evidence-based learning

IBM Watson- The Science Behind an Answer The system is workload optimized, integrating massively parallel POWER7 processors and being built on IBM's DeepQA technology, which it uses to generate hypotheses, gather massive evidence, and analyze data.

Watson is composed of a cluster of ninety IBM Power 750 servers, each of which uses a 3.5 GHz POWER7 eight core processor, with four threads per core. In total, the system has 2,880 POWER7 processor cores and has 16 terabytes of RAM. Watson can process 500 gigabytes, the equivalent of a million books, per second.

RAM. Watson can process 500 gigabytes, the equivalent of a million books, per second.

Data The IBM team provided Watson with millions of documents, including dictionaries, encyclopedias, and other reference material that it could use to build its knowledge.

Applications According to IBM, "The goal is to have computers start to interact in natural human terms across a range of applications and processes, understanding the questions that humans ask and providing answers that humans can understand and justify."

20-03-2014 IBM’s Watson to help sequence cancer DNA IBM is teaming up with the New York Genome Center to help fight brain cancer. The company said on Wednesday that its Watson cloud computing system will be used in partnership with a New York-based genetic research center mainly to help sequence DNA for the treatment of glioblastoma, the most common type of brain cancer in U.S. adults. New York Genome Center, a consortium of academic, medical and industry officials, will use Watson to sequence the DNA of cancer tumours at a much faster rate than would be possible if done by a human being. The DNA information would then be combined with clinical information and fed to Watson to help determine the best way to treat a particular patient

Or tell her “I’m drunk.” Her answers are artificially intelligent • Right now these artificially intelligent machines are pretty cute and innocent, but as they are given more power in society, these machines may not take long to spiral out of control • Silicon Valley’s resident futurist, Elon Musk, recently said artificial intelligence is “potentially more dangerous than nukes.” • Stephen Hawking wrote that successful AI “would be the biggest event in human history. Unfortunately, it might also be the last.” • There is a long list of computer experts and science fiction writers also fearful of a rogue robot-infested future • Two main problems with artificial intelligence- ○ we are starting to create machines that can make decisions like humans, but these machines don’t have morality and likely never will ○ once we build systems that are as intelligent as humans, these intelligent machines will be able to build smarter machines, often referred to as superintelligence • More scarier is how these technologies will be used by the military. Countries can engage in an arms race to build machines that can kill

03-12-2014 Stephen Hawking warns artificial intelligence 'could spell end of human race' • British theoretical physicist Stephen Hawking has warned that development of artificial intelligence could mean the end of humanity • He said such technology could rapidly evolve & overtake mankind (a scenario like that envisaged in the "Terminator" movies) • Once humans develop artificial intelligence it would take off on its own, & re-design itself at an ever increasing rate

17-01-2015 • Elon Musk, in Dec 2014, likened research in artificial intelligence to “summoning the demon” • Stephen Hawking had endorsed Musk’s fears, pointing out that since humans would evolve much slower than autonomous machines, they would become history in a Darwinian holocaust • The market for expert systems, standalone intelligences & machines which use data in unprecedented quantities & possibly unforeseen ways is expected to explode into a new industry segment • Musk, along with Hawking, also led a signature campaign among AI specialists which calls for giving direction to the technology • Instead, the industry has been focused on how AI can be monetised. The fear is that the technology is being made ready to market before its human implications are completely understood • Also, safety has been in question since Isaac Asimov’s laws of robotics. Can an autonomous entity loosed into the wild be recalled for a programming error (like automobile manufacturers do when they detect a design flaw?) • Real issues like what would be the social implications of leisure, which must result if machines take over human work? • AI may change human history more profoundly than antibiotics, nuclear physics, & its effects must be urgently understood, in advance

• The first step is to understand what computers can now do & what they are likely to be able to do in the future ○ Thanks to the rise in processing power & the growing abundance of digitally available data, AI is enjoying a boom in its capabilities ○ Today’s “deep learning” systems, by mimicking the layers of neurons in a human brain & crunching vast amounts of data, can teach themselves to perform some tasks, from pattern recognition to translation, almost as well as humans can ○ As a result, things that once called for a mind—from interpreting pictures to playing the video game “Frogger”— are now within the scope of computer programs ○ DeepFace, an algorithm unveiled by Facebook in 2014, can recognise individual human faces in images 97% of the time • Importantly, this capacity is narrow & specific ○ Today’s AI produces the semblance of intelligence through brute number-crunching force, without any great interest in approximating how minds equip humans with autonomy, interests & desires ○ Computers do not yet have anything approaching the wide, fluid ability to infer, judge & decide that is associated with intelligence in the conventional human sense • Yet AI is already powerful enough to make a dramatic difference to human life ○ It can already enhance human endeavour by complementing what people can do ○ Think of chess, which computers now play better than any person ○ Amalgamated teams of humans & algorithms. Such collectives will become the norm in all sorts of pursuits: . supported by AI, doctors will have a vastly augmented ability to spot cancers in medical images . Speech-recognition algorithms running on smartphones will bring the internet to many millions of illiterate people in developing countries . Digital assistants will suggest promising hypotheses for academic research . Image-classification algorithms will allow wearable computers to layer useful information onto people’s views of the real world • Even in the short run, not all the consequences will be positive ○ Consider, for eg, the power that AI brings to the apparatus of state security, in both autocracies & democracies ○ The capacity to monitor billions of conversations & to pick out every citizen from the crowd by his voice or her face poses grave threats to liberty • Even when there are broad gains for society, many individuals will lose out from AI ○ Humans who performed endless calculations for their higher-ups & their place was taken away by transistors, so AI will probably turf out whole regiments of white-collar workers ○ Education & training will help & the wealth produced with the aid of AI will be spent on new pursuits that generate new jobs. But workers are doomed to dislocations • The real threat is of autonomous machines with superhuman cognitive capacity & interests that conflict with those of Homo sapiens ○ Such artificially intelligent beings are still a very long way off; indeed, it may never be possible to create them • Today govt bureaucracies, markets & armies, all can do things which unaided, unorganised humans cannot ○ All need autonomy to function, all can take on life of their own & all can do great harm if not set up in a just manner & governed by laws & regulations ○ Coz systems designers cannot foresee every set of circumstances, there must also be an off-switch ○ Just as armies need civilian oversight, markets are regulated & bureaucracies must be transparent & accountable, so AI systems must be open to scrutiny ○ These constraints can be put in place without compromising progress

22-09-2015 • A new approach named "deep learning" through which computers possess the pattern-recognition skills— identifying faces, interpreting pictures, listening to speech & the like—that were long thought to be the preserve of humans • Researchers, from startups to giant corporations, are now planning to put AI to work to solve more serious problems ○ For eg., to screen risk factors of a disease etc.

3D Printing 04 January 2014 17:02

3D printing is part of the additive manufacturing (AM) family, which refers to the creation of an object by adding materials or additives to the object layer by layer • 3D printing has rapidly grown (& is still growing) to the extent that people are using it to produce firearms, jaw bones, prosthetics, automobiles, clothes, art, manufacturing components & other sundry objects

Uses of 3D printing • Personnel shopping • Artists imagination • Fashion Designing

3D printing in space

The 3D Printing in Zero-G Experiment will validate the capability of additive manufacturing in zero-gravity.

Imagine an astronaut needing to make a life-or-death repair on the International Space Station. Rather than hoping that the necessary parts and tools are on the station already, what if the parts could be 3D printed when they needed them?. All space missions today are completely dependent on Earth and the launch vehicles that send equipment to space. The greater the distance from Earth and the longer the duration, the more difficult it will be to resupply materials.

"As Nasa ventures further into space, whether redirecting an asteroid or sending humans to Mars, we will need transformative technology to reduce cargo weight and volume," Nasa Administrator Charles Bolden said during a recent tour of the agency's Ames Research Center at Moffett Field.

"In the future, perhaps astronauts will be able to print the tools or components they need while in space," he said.

The Made in Space and Nasa team envisions a future where space missions can be virtually self-sufficient and manufacture most of what they need in space.

This includes such things as consumables, common tools, and replacements for lost or broken parts and eventually even such things as CubeSats (small, deployable satellites).

"The 3D printing experiment with Nasa is a step towards the future. The ability to 3D print parts and tools on-demand greatly increases the reliability and safety of space missions while also dropping the cost by orders of magnitude," said Kemmer.

"The first printers will start by building test coupons, and will then build a broad range of parts, such as tools and science equipment," Kemmer said.

Both Made in Space and Nasa view the space station as the place to initiate the journey of in-.

"We're taking additive manufacturing technology to new heights, by working with Made in Space to test 3D printing aboard the space station," said Michael Gazarik, Nasa's associate administrator for in Washington.

In preparation for the 2014 launch, Made in Space tested a diverse array of 3D printing technologies in zero-gravity in 2011 and is conducting additional tests this year. These micro-gravity tests provide the initial research that fed into the developments for the 3D Print experiment.

The 3D Printer is built specifically to handle the environmental challenges of space and uses extrusion additive manufacturing, which builds objects layer by layer out of polymers and other materials.

Nasa sending world's first 3-D printer into space Nasa is set to launch world's first zero-G-ready 3D printer into space next year, during its resupply mission to the International Space Station, so that parts can be built on-demand in space. Space manufacturing company Made in Space's customised 3D printer will be the first device to manufacture parts away from planet Earth.

3D Printing and Defence: A Silent Revolution Imagine a technician in a war zone sending an e-mail along with a digital scan of an unserviceable part of an armoured fighting vehicle which then gets printed at the nearest available 3D printer and delivered to him in no time. This can possibly minimize the need of carrying and maintaining large inventories in battle zone. This revolution is taking place in a very silent manner and is likely to have far reaching implications for supply chain and logistics management of the armed forces. In a 3D printing technology, an object is created layer by layer through a specially designed printer using plastic or other materials. The history of 3D printing dates back to 1984 when commercial 3D printing was based on ‘stereolithography’ technique in which ultraviolet beams were used to trace a slice of an object on the surface of liquid ‘photopolymer’ resulting in the hardening of the ‘photopolymer’. The process is repeated over several layers depending upon the shape and size of the object, till the complete object is printed. As mentioned, 3D printing is likely to alter the ways in which supply chains and logistics are maintained in defence forces. For any supply chain the key elements are the manufacturer, goods/supply carrier and the end user. Considering the range and depth of the inventory maintained by defence forces, the supply chain and logistic lines of control stretches from one end of the country to remote border areas as also several hundred nautical miles into the sea carrying millions of tons of stores comprising of ammunition, spares and components, minor and major assemblies etc. Some of these stores are sensitive and a large number of them have limited shelf life. Operational readiness of defence forces largely depend upon the serviceability state of equipment in the hands of the troops. Often, non-availability of critical spares and components leads to non-availability of equipments and weapons to the troops, seriously hampering their war-fighting capability and especially when it comes to vintage foreign origin equipments. Once the digital scan or drawing is made available, the component can be straightway printed by a suitable 3D printer and raw material made available close to the site of breakdown in repair workshops. To start with, critical components of armoured fighting vehicles, small arms, field guns, UAVs, aircraft components etc. can be identified for printing onsite or close to the deployment of equipment which will drastically reduce the downtime of the equipment. Logistic tails thus will get reduced, reducing security risk with favorable economy of scales. The advantage of 3D printing also lies in its efficiency. The waste generated during traditional manufacturing is drastically reduced by 3D printing. The labour can also be reduced by 3D printing. The most striking thing about 3D printing is the way it can convert the digital inventory into physical objects thereby reducing the requirement of critical storage space drastically. Navy is in an advantageous position since it allows digital inventory to be carried onboard ships and submarines. Disaster relief is also one area where 3D printing can aid the relief operation. Shelters can be printed onsite as per the requirement. Walls of these shelters are printed using special blend of cement and there strength is found to much higher than traditional walls due to layer by layer printing. Another area where defence forces have its utility is healthcare. There is a possibility in the near future of bio-printing drugs and vaccines.Instead of keeping the sensitive

healthcare. There is a possibility in the near future of bio-printing drugs and vaccines.Instead of keeping the sensitive drugs and vaccines close to battlefield, they can be simply printed through 3D printer to avert any pandemic or provide defence against a possible biological or chemical attack. Bio printing machines are able to recreate heart tissues, lungs, jaw bones and other prosthetics limbs which will prove to be very useful for military hospitals for onsite treatment when removal of patient is not possible. The US Army has started experimenting with logistics based on 3D printing. Its Rapid Equipping Force (REF) has been assigned with 3D printers and have been deployed in war zones of West Asia. The US government has launched a 30 million dollar pilot programme for research on 3D printing and NASA is likely to launch its first 3D printer in space sometime in 2014. China is also not far behind and is likely to expand its 3D printing capabilities many folds in next 3 years. In May 2013, China showcased the world’s largest titanium aircraft critical component produced using 3D Laser Direct Manufacturing technology. This technology if adopted by Indian defence forces will have a broad effect on the long supply chains being maintained thus reducing the cost of its maintenance substantially.Components which are critical to functioning of any vehicle or combat equipment can be identified by each of the three services and by placing the 3D printers along with raw material and digital designs at key locations these components can be churned out as and when needed. This will save the exchequer on maintaining the storage space, shelf life and manpower needed to maintain the long supply chains. 3D printing technology is going through a phase of evolution but at the same time there are certain flip sides which also need to be taken into consideration before its mass utilization by defence forces. First, replacement parts which in war fighting machines are very critical have to be ensured for their safety standards since quality of 3D printer, the material used and the environment in which they are created has serious bearing.Therefore, standards are needed which are virtually non-existent world over. Secondly, printing of parts also requires purchasing intellectual property rights from original equipment manufacturer (OEM) which may cost a substantial amount to exchequer.Thirdly, the ease with which parts can be printed does raise serious questions. Anyone holding digital designs with printing capability can churn out critical parts which have serious implications for national security. Digital designs of weapons falling into the hands terrorist organizations can result in disastrous situation. Further, if an adversary lays his hands on digital files of proprietary designs, there is a possibility of altering the designs by hacking into the digital repository. Therefore, cyber security will assume greater importance. 3D printing technology is still in nascent stage. However, it is not difficult to imagine as to how it will drastically enhance the capabilities of defence forces

Pritzker Architecture Prize 03 April 2014 07:49 Pritzker Architecture Prize 03-04-2014 The Pritzker Architecture Prize, the most distinguished and celebrated award in architecture, is given to a professional in the field who has contributed substantially to humanity and displayed excellence in built work.

Awarded this year to Shigeru Ban, the 56-year-old Japanese architect, the Prize has truly met its objective after a long time. Mr. Ban has built inexpensive, easily transportable and recyclable disaster relief structures across the world for two decades. His ingenious designs have converted cardboard, paper and other relatively inexpensive materials into useful and reliable building components. He has utilised them in challenging situations ranging from earthquake- disaster relief work in Bhuj to refugee structures in Rwanda. Not many architects commit their skills and resources to design for the needy. Their preoccupation has been with creating expensive, glitzy and monumental structures, and major awards, including the Pritzker Prize, thus far have favoured such less socially relevant projects.

This year’s Pritzker Prize raises a key question for Indian architects and policymakers to reflect on: if good design brings in innovation and adds value, why are they not increasingly deployed to serve the public good? Organisations such as the Design Council of the U.K., which advises the government on matters of design, have repeatedly demonstrated that creative solutions can improve the quality of everyday life and deliver public services efficiently. They have also shown that funds invested in design fetch profits and social value. Such savings are critical for fund-starved projects such as low-cost housing. In contrast, State departments in India pay hardly any attention to design. As a result, low-income housing projects impose unliveable environments on the poor, and cities are yet to see well-designed bus stops, easily maintainable public toilets and user-friendly civic buildings. Even the National Design Policy, announced in 2007, has not sufficiently focussed on socially useful products. Architecture has to rediscover its social purpose to stay relevant. Professional education and public policy must enable it to serve those in need than just those who can pay for it.

UAVs 03 April 2014 12:05 Unmanned Aerial Vehicles (UAVs)

Uses • Used as a tool in journalism • US govt’s targeted killing of people linked to terrorism • Remotely controlled drone to spy on the nests of endangered breeds & monitor progress of reintroduced species • Drone helps police scan areas of conflict like communal violence. This helps in taking decisions on movement of police personnel, to scan trouble spots & monitor crowds • Drones can be used for atmospheric & weather monitoring, disaster response, voice & data communications • aerial surveys, aerial observation & surveillance, including filming & forest fire surveillance activities, aerial advertising, radio & TV emissions • In construction sites it allows manual work to be monitored & scrutinised • Filmmakers are increasingly using drones to get close & wide-angle shots of the action sequences in movies • UAVs help pinpoint Chinese transgression in border areas • UAVs can map high-altitude glaciers ○ provides data to inform local water management decisions

04-12-2013 UN using drones in Congo

01-03-2014 Drone satellite- ‘atmospheric satellites’ or atmostat • capable of flying at high altitude for up to 5 yrs at a time & solar-powered is a more cost-effective alternative to orbital satellites • They are dubbed as ‘atmospheric satellites’ (Atmosat) • could fulfil the role of a near-Earth satellite at a fraction of the cost & without needing to be launched into orbit

03-04-2014 Drone Journalism

• Fitted with cameras & transmitters, drones are now helping journalists capture scenes that would otherwise put their lives in danger • They let journalists capture scenes that previously would have put their lives in danger, & make it harder for govts to lie (used in protests against govts) • Drones are helping journalists overcome logistical hurdles, too. They have recently been used to cover fires raging in the Australian bush, & floods in southern England • Their relative cheapness is an added benefit. Their usefulness will only grow as cameras get better & batteries last longer

UAVs in defence

• Unmanned aerial vehicles have become a must-have in the armoury of advanced militaries to fire missiles precisely on targets thousands of miles away

on targets thousands of miles away •

India's UAV development project

• Unmanned aerial vehicles (UAVs) have become a must-have in the armoury of advanced militaries to fire missiles precisely on targets thousands of miles away • Nishant: is an UAV developed for Indian Army for surveillance applications • It was taken up in 1995 & 4 units were given to the Army in 2011 • UAVs also to be used in tackling Maoists

20-11-2015 • With the last of the 4 Nishant UAVs with the Army crashing, India’s much-delayed project to develop a basic UAV lies in a shambles • The DRDO has been working on a wheeled version, called Panchi, which can take of from short runways

21-05-2014 Drones as anti-missile defence

The best time to shoot down a hostile missile is straight after take-off. During this initial “boost phase” it moves more slowly, is easier to spot (because its exhaust plumes are so hot) and presents a bigger target (having not yet ditched its first-stage fuel tanks). A bonus is that the debris may come crashing down on the country that launched it—your enemy—rather than you

Ethical issues of drones in military

Analysis • The effectiveness of the drones — the “clean precision” of “war from a distance” has dominated policy discourse, often undermining the legal & ethical principles that underpin the right to kill • For Eg. The US used drones to target terror groups in Afghanistan & Pakistan (caused uproar in Pakistan) ○ But there are evidences which found number of flaws in the killings based on unreliable information ○ Many civilians have also got killed in these drone strikes • The War will then no longer be fought in the battlefield, but in battlezones Pro drones in military • Armed UAVs make killing antiseptic, distancing combatants from the bloody reality of war • It allows a fighter to strike from a distance from where his or her adversary cannot strike back • Some of the arguments against drones reflect little more than technophobia • Machines may prove better-able to make life-&-death judgments than emotional, terrified soldiers • History of warfare tells that civilian casualties are unavoidable especially in populated areas Against drones in military • Killing by drones rule out even the smallest chance of capture or surrender & hence exclude the prospect of criminal justice • Military drone systems have violent & dehumanising potential • Drone can become extra judicial weapons of state terror, state-perpetrated criminality & surveillance • This also means that a powerful country will have 'right to pursue' its intended “target” whenever & wherever with impunity, & with scant regard for the territorial sovereignty of the other nations

UAVs in agriculture

UAVs in agriculture

08-06-2014 • Drones offer farmers an easy way to check progress of crops • For farmers, aerial photographs taken by drones offer a quick & easy way to check on the progress of crops & determine where they may need to replant or direct pesticide applications

29-01-2015 • Drones play key role in precision farming • Drones are being used by scientists in site-specific research related to irrigation, plant growth, nutrient management, herbicide application & with more potential applications

06-10-2015 UAVs to help gauge crop damage • The Centre has decided to use satellite & UAVs over farmers’ fields to collect crop yield data & to assess damage from natural calamities

05-11-2014 For Chhath Puja & Muharram, Delhi Police used drones to monitor the situation

22-12-2014 Drones can be used for ocean surveillance like providing real-time intelligence, surveillance & reconnaissance over vast ocean & coastal regions

11-01-2015 • Apart from their traditional use for aerial surveillance, research, & combat purposes, they are increasingly being used for things like commercial photography & cinematography • In the world of professional sports, they were used to film skiing & snowboarding events during the 2014 Winter Olympics in Sochi • They even helped the police; the first drone-assisted arrest — that of a North Dakota cattle rancher — took place in January, 2014 • Prime Air, Amazon’s flagship delivery service that promises to “get packages into customers’ hands in 30 minutes or less using UAVs (currently pending FAA approval)

21-01-2015 • Drones can be employed in conservation of forests & wild animals & protect them against poachers • Drones to help curb illegal fishing in protected marine sanctuaries

04-03-2015 Regulator set to clear norms for commercial use of drones • India is set to enter an exclusive club of just 5 countries worldwide with the DGCA working on notifying regulations for commercial use of drones soon • Globally, US, Spain, Australia & New Zealand have notified provisional norms for civilian use of UAVs • In Oct 2014, India had banned private organisations & individuals from launching UAVs • Apart from DGCA approval, the move will require clearance from the air navigation service provider, the ministries of defence & home affairs & other concerned agencies • The useful aspects of civilian drones are well known — agriculture, wildlife conservation, search & rescue, aerial photography, perimeter security, remote monitoring of utilities such as transmission towers, pipelines, highways, railways, etc, tracking of natural disasters &, lately, doorstep delivery of products • However, drones also hold potential risks. Besides debates about their use for intrusive surveillance, battery failure or loss of navigational control could cause accidents • Given its multifarious applications & damage potential, ownership & operation of drones need to be licensed. Its size, capabilities, aerial route & end-use of collected data need to be monitored • Need to look at ways to define flight paths, height & areas of operation so that UAVs do not pose a hazard in manned air traffic operations

10-05-2015 • Coal India Limited to use drones to increase coal production

Drones as threat to security

07-05-2015 • In the hands of criminals, small drones could be a menace. Now is the time to think about how to detect them & knock them down safely ○ A drone carrying radioactive sand landed on the roof of the Japanese PMO in Tokyo in 2015 ○ Last year more than a dozen French nuclear plants were buzzed by them ○ In Jan 2015, a drone crashed on the White House lawn • The employment of drones for nefarious, or potentially nefarious, purposes thus seems to have begun in earnest • It is only a matter of time before somebody attempts to use a drone, perhaps carrying an explosive payload, to cause serious damage or injury • Need for anti-drone "detect & defeat" systems ○ Detecting a small drone is not easy. Such drones are slow-moving & often low-flying, which makes it awkward for radar to pick them up, especially in the clutter of a busy urban environment ○ "Defeating" a detected drone is similarly fraught with difficulty. You might be able to jam its control signals, to direct another drone to catch or ram it, or to trace its control signals to find its operator & then "defeat" him instead ○ But all of this would need to take place, as far as possible, without disrupting local Wi-Fi systems (drones are often controlled by Wi-Fi), & it would certainly have to avoid any risk of injuring innocent bystanders

11-07-2015 • Flying drones in India has been banned since October 2014

Wearable technology 12 March 2015 15:56

CuteCircuit’s dress The terms ‘wearable technology’, ‘wearable devices’, & ‘wearables’ all refer to electronic technologies or computers that are incorporated into items of clothing & accessories which can comfortably be worn on the body • examples being , smart watches

Google glass

• Glass is basically a small wearable computer that is being developed by Google, with a camera and a display screen (optical head-mounted display) above the wearer’s right eye. The device sits roughly at eyebrow level, higher than where eyeglasses would go • Akin to wearing a smartphone without having to hold it in your hands, that can communicate with the Internet via natural language voice commands. It lets wearers surf the Web, ask for directions and take photos or videos. Glass also lets people read their email, share photos on Twitter and Facebook, translate phrases while travelling or partake in video chats. Glass follows some basic voice commands, spoken after the words “OK, Glass”

Google is adding prescription frames and new styles of detachable sunglasses to its computerised, internet-connected goggles known as Glass.

12-10-2014 Use in medical field • It allows distant instant consultation with seniors who could be watching the surgical procedure being performed & also it is a great experience for juniors to watch operations through the eyes of people with years of experience. • A surgeon can also go through medical papers while performing surgery on the table for quick reference. Hence it can improve the safety & efficiency of surgeries performed

18-03-2015 • Wearables, mobile devices containing circuitry to gather & display information, include a diverse wardrobe of products, such as clothes that measure exertion & glasses that overlay information & augmented images on real-life vistas • 21 million wearable devices were sold in 2014; wrist-worn wearables, including watches, were the majority • Several companies are offering small gadgets that use GPS technology to track children who might wander off • A British startup, has designed a smart shirt that reproduces the feeling of being hugged when someone sends the wearer a text message • Health is an area of particular promise ○ Watches & other wearables can help people monitor their activity & encourage them to exercise ○ Thanks largely to the smartphone boom, chips & sensors have become cheaper & smaller • Some analysts think wearables’ killer feature may eventually be that they will provide their users with a “persistent” digital identity, melding the functions of a driving licence, credit card, house key, car key & computer in one small gadget worn on the wrist or neck • In factories & warehouses, smart glasses could make it more efficient to locate & handle stock—& to keep an eye

• In factories & warehouses, smart glasses could make it more efficient to locate & handle stock—& to keep an eye on workers’ productivity • Mining & oil firms could use wearables to monitor the safety of employees in hazardous situations • Spanish startup, is working on a sports shirt with an embedded camera, to give fans a players’ eye view of the action • Wearable devices hold the potential to transform some industries ○ Clinical trials could become cheaper & more accurate if drugmakers give wearable monitors to the patients taking part ○ Hospitals & doctors’ surgeries could use such monitors to reduce the need for home visits ○ Insurance firms could enter a new age in which they reduce risk as well as provide cover for it • Consumers may benefit in the end, but the buyers of the wearable devices will be businesses ○ One American health insurer is already handing out health-monitoring bands to customers, promising lower premiums for those who exercise more (see article). Banks could reward customers who use the identity- verifying features of wearables, to cut the risk of card fraud • The opportunities are boundless, but so are the dilemmas ○ Wearable devices are highly personal, but that exposes people to real risks ○ As consumers quantify more of their lives & store more of their health & medical data electronically, the chance that they could be compromised rises ○ Currently there is no straightforward way to revoke personal information should a wearable device be lost or stolen ○ Wearables provide “a new avenue of attack” for cyber-criminals ○ Such fears will need to be assuaged for consumers to become as enthusiastic about wearables as the many companies now working on them

28-03-2015 Wearable tech from India: Footwear that shows the way

Robotics 08 February 2014 13:23

Uses of robots • SeaBed robots using sonar can analyse ice thickness of sea ice at an underwater depth • Robot Journalist used in news media for ingesting, computing, generating outputs • Robots are now being employed to protect the International Space Station (ISS) from potentially damaging space junk and help repair defunct satellites

01-04-2014 Robots are as good, or as bad, as the people who make them • Isaac Asimov was wrong to think that the laws of robotics would be hard-wired into every robot brain. He was right, though, to think that robots would need regulation, and that such regulation would cause heated debate on the role that they might play • For the market for robots to develop, laws & regulations will be crucial • The uptake of industrial robots has always been constrained by health-&-safety considerations • Autonomy for lethal military robots remains a serious concern • The spread of civilian drones will depend on freeing up airspace, along with bandwidth for their control • The advent of self-driving cars opens up all sorts of legal & regulatory issues • Manufacturers’ technical ability to produce robots that can help in the home might easily outrun their capacity to deal with the resulting liability issues, especially if the robots operate in the homes of elderly people with cognitive difficulties • It needs to be seen that how acceptable it is for robots to be designed to fool people into thinking that they have feelings ○ Robots have no will of their own; they are machines designed for an end, & it is that end which regulators need to concentrate on • In “Das Kapital”, Karl Marx argued that fetishising money & commodities as “figures endowed with a life of their own, which enter into relations both with each other & with the human race” blinds people to the social relationships built into the world of trade & economics ○ Subsequent generations have noted that technology is often similarly fetishised ○ Robots are also an eg. of such fetishisation Means & ends • In a weapons system, the precise level of autonomy is probably less important than the discrimination & care with which the person responsible for the system handles it ○ For eg. If a civilian drone is used as a tool by a Peeping Tom, it is the peeping, not the drone, that should be penalised • Robots will get better at seeing things, manipulating things & moving things around, just as they have got better at walking ○ Clearly there will be limits to the things robots can do. But such limits are not yet in sight

01-04-2014 New roles for technology- Rise of the robots Prepare for a robot invasion. It will change the way people think about technology ROBOTS came into the world as a literary device whereby the writers and film-makers of the early 20th century could explore their hopes and fears about technology, as the era of the automobile, telephone and aeroplane picked up its reckless jazz-age speed. From Fritz Lang’s “Metropolis” and Isaac Asimov’s “I, Robot” to “WALL-E” and the “Terminator” films, and in countless iterations in between, they have succeeded admirably in their task Since moving from the page and screen to real life, robots have been a mild disappointment. They do some things that humans cannot do themselves, like exploring Mars, and a host of things people do not much want to do, like dealing with unexploded bombs or vacuuming floors (there are around 10m robot vacuum cleaners wandering the carpets of the world). And they are very useful in bits of manufacturing. But reliable robots—especially ones required to work beyond the safety cages of a factory floor—have proved hard to make, and robots are still pretty stupid. So although they fascinate people, they have not yet made much of a mark on the world That seems about to change. The exponential growth in the power of silicon chips, digital sensors and high-bandwidth communications improves robots just as it improves all sorts of other products. And, as our special report this week

Technology Page 27 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

communications improves robots just as it improves all sorts of other products. And, as our special report this week explains, three other factors are at play One is that robotics R&D is getting easier. New shared standards make good ideas easily portable from one robot platform to another. And accumulated know-how means that building such platforms is getting a lot cheaper. A robot like Rethink Robotics’s Baxter, with two arms and a remarkably easy, intuitive programming interface, would have been barely conceivable ten years ago. Now you can buy one for $25,000 C3 IPO A second factor is investment. The biggest robot news of 2013 was that Google bought eight promising robot startups. Rich and well led (by Andy Rubin, who masterminded the Android operating system) and with access to world-beating expertise in cloud computing and artificial intelligence, both highly relevant, Google’s robot programme promises the possibility of something spectacular—though no one outside the company knows what that might be. Amazon, too, is betting on robots, both to automate its warehouses and, more speculatively, to make deliveries by drone. In South Korea and elsewhere companies are moving robot technology to new areas of manufacturing, and eyeing services. Venture capitalists see a much better chance of a profitable exit from a robotics startup than they used to The third factor is imagination. In the past few years, clever companies have seen ways to make robots work as grips and gaffers on film sets (“Gravity” could not have been shot without robots moving the cameras and lights) and panel installers at solar-power plants. More people will grasp how a robotic attribute such as high precision or fast reactions or independent locomotion can be integrated into a profitable business; eventually some of them will build mass markets. Aerial robots—drones—may be in the vanguard here. They will let farmers tend their crops in new ways, give citizens, journalists and broadcasters new perspectives on events big and small (see article), monitor traffic and fires, look for infrastructure in need of repair and much more besides As consumers and citizens, people will benefit greatly from the rise of the robots. Whether they will as workers is less clear, for the robots’ growing competence may make some human labour redundant. Aetheon’s Tugs, for instance, which take hospital trolleys where they are needed, are ready to take over much of the work that porters do today. Kiva’s warehouse robots make it possible for Amazon to send out more parcels with fewer workers. Driverless cars could displace the millions of people employed behind the wheel today. Just as employment in agriculture, which used to provide almost all the jobs in the pre-modern era, now accounts for only 2% of rich-world employment so jobs in today’s manufacturing and services industries may be forced to retreat before the march of the robots. Whether humanity will find new ways of using its labour, or the future will be given over to forced leisure, is a matter of much worried debate among economists. Either way, robots will probably get the credit or blame Invisible and otherwise Robotic prowess will to some extent be taken for granted. It will be in the nature of cars to drive themselves, of floors to be clean and of supplies to move around hospitals and offices; the robotic underpinning of such things will be invisible. But robots will not just animate the inanimate environment. They will inhabit it alongside their masters, fulfilling all sorts of needs. Some, like Baxter, will help make and move things, some will provide care, some just comfort or companionship. A Japanese robot resembling a baby seal, which responds amiably to stroking and can distinguish voices, seems to help elderly patients with dementia The more visible robots are, the better they can help humanity discuss questions like those first posed in fiction. Is it necessary that wars always be fought by people who can feel pity and offer clemency, and yet who can also be cruel beyond all tactical requirements? (Already America is arguing about whether drone pilots deserve medals—see article.) Does it matter if the last kindnesses a person feels are from a machine? What dignifies human endeavour if the labour of most, or all, humans becomes surplus to requirements? People, companies and governments find it hard to discuss the ultimate goals of technological change in the abstract. The great insight of Asimov et al was that it is easier to ask such questions when the technology is personified: when you can look it in the face. Like spacefarers gazing back at the home planet, robots can serve not just as workers and partners, but as purveyors of new perspectives—not least when the people looking at them see the robots looking back, as they one day will, with something approaching understanding

Kirobo- World’s first talking robot

Technology Page 28 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• World’s first talking robot Kirobo was successfully sent into space on 4 August 2013 by Japanese Scientists. • The robot was sent by H2B rocket from the island of Tanegashima. The rocket carried food, water and other supplies. Kirobo will serve as a companion for Japanese astronauts.Kirobo was put through a series of zero-gravity and other safety tests prior to sending him into space. Kirobo is 34 centimetres tall and can speak Japanese. It will provide emotional support for people in space. The main features of kirobo are as following- • Kirobo will talk to JAXA astronaut Koichi Wakata when he arrives at the space station in November 2012. • The name of Kirobo is a merging of Kibo and robot. • Kirobo was designed by scientists and engineers at the University of Tokyo. • It is equipped with voice-recognition and face-recognition technology, as well as a camera, emotion recognition software and natural language processing

Sperm-based ‘biobots’ Scientists created sperm-based ‘biobots’ [Spermbots] in Germany Scientists led by Oliver Schmidt created the biological robots or biobots powered by sperm in the Institute for Integrative Nanosciences in Dresden, Germany on December 2013. It is also called as biohybrid micro-robot. The researchers created magnetic nanotubes that were 50 microns long by 5 to 8 microns in diameter and dropped these into a fluid containing bull sperm. The tubes were narrower at one end to stop the sperm from escaping and can be rotated by using magnetic fields. The tail-like flagellum of the sperm cell sticks outside the end of the tube and power the bibot like a propeller Benefits These “biobots” can be used to guide individual sperm or to deliver targeted doses of drugs or fertilizing an egg. Schmidt Said that sperm cells are an attractive option because they are harmless to the human body, do not require an external power source and swam through viscous liquids. Till now researchers has only managed to persuade groups of cells to cooperate with the help of chemical gradients and magnetic fields

ERWIN (Emotional Robot with Intelligent Network) ERWIN (Emotional Robot with Intelligent Network) has been developed at the University of Lincoln as part of a study attempting to understand how long-term relationships may be forged between humans and androids. These durable relationships could be important in cases where a robot operates as a personal aid or companion, for example when providing care for the elderly or support for people with autism.

Dr John Murray, from the School of Computer Science at Lincoln, is behind the ‘friendly robot’, which is now being used in a new study carried out by Indian PhD student Mriganka Biswas

Biswas said: "When two people interact for the first time, if the two different personalities attract each other, a relationship forms. But, in the case of conventional human-robot interaction, after gathering information about the robot, the robot's lack of identifiable characteristics and personality prevents any relationship bond developing." The key obstacle in forming a bond with a robot may lie in our flawed human thought processes. As humans, we have the tendency to use certain illogical patterns of thought, or cognitive biases, when making judgements about the world

Technology Page 29 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

the tendency to use certain illogical patterns of thought, or cognitive biases, when making judgements about the world and other people around us. We do this because these shortcuts allow us to make quicker decisions and free up our limited mental space for dealing with unfamiliar input. Our biases shape our personality, and according to Biswas, are what make us human.

Computers and robots, on the other hand, generally operate according to rational rules, which make them seem very far removed from us. Introducing cognitive bias to a robot and giving it personality traits will render it more human- like. As demonstrated in the video, ERWIN can express five basic emotions whilst interacting with us

Nanotechnology is the science of interacting with atoms & molecules to modify the way they behave. Materials behave differently in the nanoworld. Scientists can direct those behaviors to create new capabilities

15-03-2014 Indian agro-scientist develops world's first nano-fertiliser

• Dr. Tarafdar has innovated nano fertiliser using biosynthesis for the first time in the world • This means that no chemicals have been used for the synthesis of nano-fertiliser • Using microbial enzymes for the breakdown of fertiliser salts into nano forms and use these as fertilisers

• These nano fertilisers increase the nutrient use efficiency by three times than conventional ones. This can reduce the use of chemical fertilisers by 80 to 100 times and hence save considerable foreign exchange. • Idea is to make nano fertilisers enter stomata of plant leaves and since nano fertilisers are encapsulted with proteins, it is easy for plants to absorb it by stomata. • Nano fertilisers are 3-4 times more cheaper than chemical ones and also give 17-55% more crop yields, hence higher return to farmers.

27-03-2014 Shrinking the mass spectrometer

IIT Madras team was able to create ions from any sample even at one volt Mass spectrometers that are as small as a smart phone and require as little as one volt — a 3,000-time reduction in potential — to create an electric field which would turn a sample into ions for identification of composition may soon become a reality. Conventionally, a solution of the sample is electrosprayed at 3,000 volts to create charged droplets that become ions. The ions are, in turn, analysed to find the composition or chemical constituents in the case of a sample mixture Nanotube dispersion technique The massive reduction in voltage requirement became possible by using carbon nanotube-impregnated paper to act as a substrate on which the sample was deposited. If the conventional method uses very high voltage to create a strong electric field, the sharp protrusions of the carbon nanotubes help in creating the high electric field by using very low voltage. He foresees a day not too far away when gently rubbing the nanotube-coated paper on any object — an apple or a tablet — will be sufficient to collect samples for analysis in a lab. The nanotube-coated substrate can also be reused. In all, there is a real possibility of completely rewriting the way sample testing gets done. “So what it means [is that] you can collect samples remotely and analyse them elsewhere for disease or pollution

“So what it means [is that] you can collect samples remotely and analyse them elsewhere for disease or pollution prevention or any such thing,” he noted. “In a sense, we can make a mass spectrometer reach a wider audience.” The mass spectrometer is a sophisticated instrument and has been out of bounds to the common man.

11-06-2014 India may contribute 25% skilled professionals required by global nanotechnology industry, ASSOCHAM TechSci study In 2011, India's share in global nanotechnology research publications had reached six per cent from a mere two per cent in the year 2000. With its major contributions in applied physics, material science and macromolecules, India had outpaced several countries like Brazil, Taiwan, the UK and France in terms of research publication, the study ascertained. "Incentives for research and development, specifying manufacturing standards, infrastructure, cost and financing, weak industry-academia link and others are certain key barriers in commercialization of nanotechnology in India," said experts. According to ASSOCHAM TechSci Research study lack of appropriate infrastructure, absence of proper skillset and expert workforce, lack of standardizations, lack of knowledge and significant brain drain are key weaknesses of nanotechnology market in India which is still at a nascent stage. However, the nanotechnology market in India is likely to witness strong growth on account of increasing government focus on developing and enhancing nanotechnology, the study added. "Besides, with growing awareness and contribution by institutions together with increased funding, India is likely to achieve significant growth in nanotechnology." Even though the Government has been highly active in funding nanotechnology development in India, the operations however, need more focus and streamlining as technology is of a multi-disciplinary nature, hence proper utilization of funds is the need of the hour. The future of nanotechnology in India is largely dependent on the scale of investment spending and ability to introduce revolutionary products in the market, further noted the study.

Graphene

Feb 2014 Graphene circuit's wireless promise The promise of faster, cheaper and more efficient wireless devices has moved a step closer. Researchers at IBM have demonstrated the most advanced integrated circuit made of wafer-scale graphene - often touted as a "wonder material" that could revolutionise electronics. Graphene circuits could allow mobile devices to transmit data loads in a much speedier manner

The material is the subject of global research efforts aimed at harnessing the extraordinary electrical, optical,

Technology Page 37 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

The material is the subject of global research efforts aimed at harnessing the extraordinary electrical, optical, mechanical and thermal properties that potentially make it a cheaper and more energy efficient choice than silicon in electronics.

"This is the first time that someone has shown graphene devices and circuits to perform modern wireless communication functions comparable to silicon technology," Experts said.

True integrated circuits based on graphene have been difficult to build because the material's nano-scale dimensions have meant that it could be easily damaged during fabrication.

14-04-2014 Graphene, the material of tomorrow Graphene is the strongest, thinnest material known to exist. A form of carbon, it can conduct electricity and heat better than anything else.

Graphene could change the electronics industry, ushering in flexible devices, supercharged quantum computers, electronic clothing and computers that can interface with the cells in your body. While the material was discovered a decade ago, it started to gain attention in 2010 when two physicists at the University of Manchester were awarded the Nobel Prize for their experiments with it. More recently, researchers have zeroed in on how to commercially produce graphene. Graphene is one of the few materials in the world that is transparent, conductive and flexible — all at the same time graphene was discovered to be 200 times stronger than steel. So what do you do with graphene? Physicists and researchers say that we will soon be able to make electronics that are thinner, faster and cheaper than anything based on silicon, with the option of making them clear and flexible. Long- lasting batteries that can be submerged in water are another possibility. In 2011, researchers at Northwestern University built a battery that incorporated graphene and silicon, which the university said could lead to a cellphone that "stayed charged for more than a week and recharged in just 15 minutes." In 2012, the American Chemical Society said that advancements in graphene were leading to touch-screen electronics that "could make cellphones as thin as a piece of paper and foldable enough to slip into a pocket." Samsung has discovered how to create high-quality graphene on silicon wafers, which could be used for the production of graphene transistors. Samsung said in a statement that these advancements meant it could start making "flexible displays, wearables and other next-generation electronic devices." Researchers at IBM, Nokia and SanDisk have been experimenting with the material to create sensors, transistors and memory storage. Graphene is inexpensive. If you think of something in today's electronics industry, it can most likely be made better, smaller and cheaper with graphene. Another fascinating aspect of graphene is its ability to be submerged in liquids without oxidizing, unlike other conductive materials. Graphene research is leading to experiments where electronics can integrate with biological systems. In other words, you could have a graphene gadget implanted in you that could read your nervous system or talk to your cells. Last year, the Bill and Melinda Gates Foundation paid for the development of a graphene-based condom that is thin, light and impenetrable. Carmakers are exploring building electronic cars with bodies made of graphene that are not only protective, but act as solar panels that charge the car's battery. Aircraft makers also hope to build planes out of graphene. If all that isn't enough, an international team of researchers based at MIT has performed tests that could lead to the creation of quantum computers, which would be a big market of computing in the future.

Mitochondrial replacement therapy (MRT) or Three parent babies

• Mitochondrial replacement therapy (MRT) is a radical new approach developed in UK for the treatment of a potentially wide spectrum of inherited (hitherto incurable) diseases • It treats women with mitochondrial disease (a range of inherited diseases caused by defective mitochondria), by replacing the dysfunctional mitochondria carried by a woman who wishes to conceive with the healthy mitochondria of a donor • The egg is then fertilised with the partner’s sperm through IVF. The embryo thus created is one technically cleansed of the mutated mitochondrial DNA that the mother originally carried • Human mitochondrial disorders are among the most common genetic diseases, affecting around one in 6500 people. They are believed to be the reason behind 150 known conditions • Mitochondria are tiny, biological "power stations" that provide energy to nearly every cell of the body & mitochondrial diseases make patients lack energy, resulting in muscle weakness, blindness, heart failure & even death

Scientists have devised two techniques that allow them to take the genetic information from the mother and place it into the egg of a donor with healthy mitochondria

Technology Page 42 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive into the egg of a donor with healthy mitochondria

A healthy embryo is created by adding the parents' pronuclei to the donor embryo, which is finally implanted into the womb

1. Eggs from a mother with damaged mitochondria and a donor with healthy mitochondria are collected 2. The nucleus, containing the majority of the genetic material, is removed from both eggs 3. The mother's nucleus is inserted into the donor egg, which can then be fertilised by sperm.

• UK has given the go ahead for clinical trials & is also drafting regulations covering the safety, efficacy & the ethical & societal aspects involved in such a method • This is very good news for patients with mitochondrial DNA disease & an important step in the prevention of transmission of serious mitochondrial disease Issues Scientific Issues: • Compatibility of imported ‘new’ mitochondria with the host cell • Unknown risks to the child Social & Ethical Issues: • it would be ethical for families to use the method in order to help the child • mitochondrial donation does not indicate, either biologically or legally, any notion of the child having either a third parent or a second mother

The Lazarus project (2nd chance at life)

• A project run by the University of Newcastle, Australia, revived the genomes of an extinct Australian frog using sophisticated cloning technology known as somatic cell nuclear transfer to implant a "dead" cell nucleus into a fresh egg from another frog species. • named as one of Time Magazine's 25 Best Inventions of the Year because it managed to resurrect the gastric- brooding frog, albeit for a short period of time. • The Rheobatrachus silus, a species of frog which became extinct in 1983, was unique in that it swallowed its eggs and gave birth orally. Scientists in the team managed to extract cell nuclei from tissues recovered in the 1970s, which had been stored for 40 years in a conventional deep freezer. • They took fresh donor eggs from the distantly related frog species, inactivated the egg nuclei and replaced them with dead nuclei from the extinct frog. Some of the eggs began spontaneously dividing and growing to early embryo stage. • None of the embryos survived beyond a few days but genetic tests confirmed the dividing cells contained genetic material from the extinct frog. • This has revived the extinct frog's genome in the process. Now they have fresh cryo-preserved cells of the extinct frog to use in future cloning experiments

Chimerism

• A chimera is a single organism (usually an animal) that is composed of two or more different populations of genetically distinct cells that originated from different zygotes involved in sexual reproduction • Commoner than realised • Twins can end up with a mixed supply of blood when they get nutrients in the womb through the same set of blood vessels . • Women can also gain genomes from their children. After a baby is born, it may leave some fetal cells behind in its mother's body, where they can travel to different organs and be absorbed into those tissues

DNA Bar Coding

• DNA barcoding is a taxonomic method that uses a short genetic marker in an organism's DNA to identify it as belonging to a particular species. Its main goal is to identify an unknown sample in terms of a preexisting classification. • Applications include, for example, identifying plant leaves even when flowers or fruit are not available, identifying insect larvae (which may have fewer diagnostic characters than adults and are frequently less well-known), identifying the diet of an animal, based on its stomach contents or faeces and identifying products in commerce (for example, herbal supplements or wood)

Reprogramming of adult cells in vivo

The reprogramming of adult cells in vivo could possibly facilitate the natural regeneration of damaged tissues • A landmark study published in Nature shows that reprogramming of adult cells that behave like stem cells can be achieved right inside the body (in vivo). Till now, reprogramming of adult cells has been achieved only in labs (in vitro). • This opens a promising window to repairing tissues right inside the body. • This in principle has several advantages. This does not require in vitro manipulation and [therefore] does not require engraftment. Engraftment is usually very inefficient. • Reprogramming of adult cells (induced pluripotent stem cells — iPS cells), say skin cells, to become embryonic-like stem cells capable of becoming any of the specialised cells like liver cells or heart cells has tremendous therapeutic benefits. • If reprogramming of adult cells inside the body is a stupendous achievement, the researchers crossed another milestone by making the reprogrammed adult cells exhibit totipotency. • For the study, the researchers used genetically modified mouse models that had all the four cell-reprogramming factors used in adult cell reprogramming; these factors could express themselves in the presence of a drug. • Several weeks after the factors were exposed to the drug, teratomas “emerged from multiple organs.” The emergence of teratomas was proof that reprogramming had occurred inside the body of the mice. • They found the totipotent primitive cells in major organs like the stomach, intestine, pancreas and kidney. Even the iPS cells circulating in the blood were found to exhibit totipotency. • One more surprise: More than the presence of primitive cells in the organs and blood, the authors found that adult cells reprogrammed inside the body of the mice could form an embryo-like structure when injected into wild mice.

• Hence, The in vivo reprogramming allows the acquisition of totipotency features that are absent in ES [embryonic stem] cells or in standard in vitro reprogrammed iPS cells

Artificial micro-humans

01-09-2014 Artificial micro-humans to replace animals in lab tests Scientists are creating artificial micro-humans that will eliminate the need for using animals in laboratory testing.

The artificial human machines, each the size of a microchip, will simulate the response of humans to substances inhaled, absorbed in the gut or circulated through the bloodstream.

Early versions comprising an artificial lung, liver, kidney, heart and gut are already being used to test cosmetics, chemicals and drugs, researchers said.

"Farms" made up of hundreds of artificial human machines could begin replacing animal laboratories within three years, doing away with the need for experiments that claim the lives of up to 90m animals each year, 'The Times' reported. substances often behave differently in animals and almost half of drugs that pass the animal tests later cause unforeseen side effects during human trials.

The new farms will eliminate such unsafe human drug trials, speed up the development of life-saving treatments and could one day be used to tailor medicine to individual patients, researchers said

Brain research: Optogenetics & CLARITY

18-01-2016 Dr.Tilak HR

• Navigating an opaque mesh of 80 billion neurons to decipher brain activity — emotions, memory & learning — or identify diseased circuitry was the greatest challenge for brain researchers till now • Two path-breaking techniques devised by Prof. Karl Deisseroth & his colleagues at Stanford University are changing the way we see, understand & control the brain • Optogenetics ○ The 1st technique “illuminates” the brain, enabling researchers to manipulate electrical activity ○ In a process called “optogenetics”, specific targetted cells are infused with a gene that directs the production of a light-sensitive protein (derived from algae or other microbes) that can then turn brain cells on or off in response to a focussed light signal • CLARITY ○ The 2nd is a “transparent brain” engineered through a method called “CLARITY” ○ This process makes brains transparent, by building a hydrogel inside the brain, removing lipids that make the brain opaque ○ This allows scientists to study the wiring of a 3-dimensional brain in its entirety, without having to laboriously dissect & reassemble tissues as has been the practice

23-01-2016 • Karl Deisseroth, a psychiatrist & neuroscientist has developed several methods to image brain circuits & observe which specific nerve cells switch on & of • Optogenetics is an emerging field that combines biology & engineering. Here, scientists use particular bacteria that contain lightsensitive proteins called opsins & these can be introduced to neuronal cells in the body. By shining a blue light, it’s possible to make certain neurons electrically activated ○ Dr. Deisseroth, since 2005, has pioneered a series of techniques to make neurons light up in real time, though for now much of these experiments are confined to rats • Another seminal method that Dr. Deisseroth has pioneered is quite simply called ‘CLARITY’ ○ This process makes brains transparent, by building a hydrogel inside the brain & removing lipids that make the brain opaque ○ Scientists can peek into the wiring of a 3-dimensional brain in its entirety, without having to laboriously dissect & reassemble tissues, as has been the norm Analysis • There are distinct pathways involved in each pyschiatric illnesses & if we can develop specific treatments, this could address the problems & make treatment more efficient • Going ahead it may be possible to control individual neurons with light beams, as well as the specific sequence of brain circuits that cause people to become addicted to cocaine • At the other end, research was progressing to improve techniques to probe the brain that could, literally, throw light on understanding the brain mechanism in emotions such as anxiety, compassion & love

12-05-2014 CSIR-IHBT Licenses Unique, Thermo-Stable SOD Enzyme to Create Global Niche CSIR-Institute of Himalayan Bioresource Technology (CSIR-IHBT), Palampur, has signed a MoU with its industrial partner, Phyto Biotech, Kolkata, to formalize Transfer of Technology for production of unique autoclavable Super Oxide Dismutase (SOD) enzyme, used in cosmetic, food and pharmaceutical industries for end applications, like developing anti-ageing creams, extending shelf life of fruits and vegetables and during cryo-surgery and preservation of organelles, respectively. The licensing has brought together the CSIR and the industry to enable commercial production of desired standard SOD so as to create a global niche for the country.

The enzyme was discovered by CSIR-IHBT during a survey at an altitude of over 10, 000 ftin the Western Himalayan region from Potentilaastrosanguniaplant growing under snow cover. Persistent hard work over the years has resulted in the isolation of the SOD gene. Thereafter,a protocol was developed for cloning of the gene in E.coli. The enzyme thus produced,retained the same unique feature as that of the native plant. Applying the knowledge of bioinformatics, the enzyme has been further engineered by mutation of a single amino acid to increase its consistency and thermo- stability.

The characteristic features of this SOD lies in its stability and functionality ranging from sub-zero to high temperature of >40°C with varying specific activity. Owing to its high antioxidant properties and multiple uses, SOD enjoys high demand and price in the global market

2013 Genome of oil palm sequenced What it is: The genome of one of the world’s main commercial crops, the oil palm, has been sequenced raising the possibility of making its production much more sustainable.

Palm is common ingredient in toothpaste, soap, fried foods and several other products we use everyday. Today, 64 million tonnes of palm oil are produced in plantations every year.

Scientists last week announced that they have finally managed to sequence the genome (the complete set of an organism’s genetic material) of the oil palm tree. They have also identified a gene called SHELL which determines how much oil the tree will produce.

Oil palms have different varieties and not all of them are suited for oil production. But cultivators usually find out if the y have the right variety only once the tree has grown. Now that we know of SHELL, cultivators can predict what variety of tree will result just by testing the seed. These high yielding varieties alone can be bred.

Why it matters: Palm oil production has a dark side to it. The trees grow best in conditions suited to rainforests. As a result, plantations have replaced vast areas of rainforest land driving several species like the pygmy elephant near extinction. Scientists say that by selectively breeding only high-yield oil palms, this deforestation can be reduced.

27-01-2014 Genetically modified biofuel to feed fish • A genetically-modified plant that produces seeds packed with fish oils is set to be grown in open fields in the U.K. • Fish oils — specifically omega-3 long-chain polyunsaturated fatty acids — have been shown to cut the risk of cardiovascular disease and are a popular food supplement. But about 80% of the fish oil harvested from the oceans every year is actually fed to other fish being raised in aquaculture. • Fish oils that benefit the health of both fish and humans, called EPA and DHA, are not in fact produced by fish themselves but instead accumulated by eating marine microbes. Mr. Napier’s team therefore took up to seven genes from algae that produce the fish oils and transplanted them into oil seed plants called camelina. It naturally produces short-chain oils and has been grown as a food crop for centuries in southern and eastern Europe and is used a biofuel crop in North America. • The GM camelina has passed laboratory and greenhouse trials and about 25 per cent of the oil in the seeds is EPA and DHA, a similar proportion to that in fish oil. harvesting the oil direct from algae would be much more expensive & require large amounts of water & energy

Policies & schemes 18 April 2014 10:35 ICMR code for bioresearch 02-03-2014 ICMR issues code for life sciences research With a view to prevent the use of scientific research for bioterrorism and bio-warfare The Indian Council of Medical Research (ICMR) has issued a mandatory code of conduct for research scientists engaged in the field of life sciences. This has been done with a view to preventing the use of scientific research for bioterrorism and bio-warfare The aim is to ensure that all research activities, involving microbial or other biological agents, or toxins, whatever their origin or method of production, are only of types and in quantities that have justification for prophylactic, protective or other peaceful purposes Ethical considerations in this Code of Conduct would be binding on all laboratory scientists involved in scientific research concerning dangerous organisms and toxic weapons against any living being or environment Bioethics has emerged as a new discipline over the past couple of decades and is poised to become a multidisciplinary specialty. Institutional review boards and ethics committees have evolved as conscience keepers of professionals with the view to safeguarding the welfare of members of society against any possible harm from scientific advances Advances in laboratory technologies have created new and complex ethical dilemmas. Laboratory services are an integral part of disease diagnosis, treatment, response monitoring, surveillance programmes and research Therefore, personnel working in clinical and/or research laboratories should be aware of their ethical responsibilities. It is necessary to comply with the ethical code of conduct prescribed by national and international organisations, and address the emerging ethical, legal and social concerns in the field of biological and biomedical sciences Pointing out that modern biology and biotechnology offer novel ways of manipulating basic life processes, the Code of Conduct says that purposefully or unintentionally, genetic modification of micro-organisms could be used to create organisms that are more virulent and antibiotic-resistant or have greater stability in the environment The scientists engaged in such research activities should be aware of the potential risks and concerns relating to science and its wider applications and the ethical responsibilities they shoulder. They should not only be aware of but also comply with the requirements of international conventions and treaties relevant to their research work, the code says

Stem cell treatment

23-02-2014 Centre issues new guidelines to check malpractice in stem cell treatment Any use of stem cell in patients will, from now on be considered research and not therapy, according to the fresh National Guidelines on Stem Cell Research issued by the government. Stem cell use in patients must only be done within the purview of an approved and monitored clinical trial with the intent to advance science and medicine, and not offer it as therapy, the guidelines issued said.“In accordance with this stringent definition, every use of stem cells in patients outside an approved clinical trial shall be considered malpractice. It is hoped that this clear definition will serve to curb the malpractice of stem cell ‘therapy’ being offered as a new tool for curing untreatable diseases,” according to the Indian Council of Medical Research and the Department of Biotechnology. The decision to drop the word ‘therapy’ was taken on the recommendation of a joint drafting committee of the ICMR and Department of Biotechnology, to emphasis the fact that stem cells are still not a part of standard of care. Hence, there can be no guidelines for therapy until efficacy is proven. These guidelines are intended to cover only stem cell research, both basic and translational, and not therapy. It has been made clear in these guidelines that any stem cell use in patients, other than that for hematopoietic (producer of red, white blood cells and platelets) stem cell reconstitution for approved indications, is investigational at present, the guidelines point out.

12-03-2014 New guidelines A revised set of guidelines on stem cell research was recently released by the Indian Council of Medical Research and the Department of Biotechnology, seven years after an earlier one was issued. Despite claiming that the revision was necessitated by a need to “reflect new scientific and clinical findings” that have changed the landscape of stem cell research being undertaken in the country and its possible translation, there is a

Technology Page 49 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

changed the landscape of stem cell research being undertaken in the country and its possible translation, there is a glaring omission that reflects a lack of application of the mind. The guidelines make it abundantly clear that any use of stem cells in patients except to treat various haematological, immunological and metabolic disorders using haematopoietic stem cells should, by default, be considered as clinical trials. The exemption is on the grounds that the use of haematopoietic stem cells to treat the said disorders has been “established as a standard of medical care.” Of course, the use of bone marrow (containing haematopoietic stem cells) to treat diseases like leukaemia has been in vogue in India since the 1960s. But what has been overlooked in the new guidelines is that treating damaged corneas by limbal transplantation for limbal stem cell deficiency should also be considered as an established method of care; limbal stem cells are transplanted from the healthy eye to the damaged eye of the same patient to treat an affected cornea. No other alternative method is currently available to treat such cases. For the last few years, a handful of tertiary eye hospitals in India have been treating such cases using limbus stem cells; since 2001, one institute alone has treated nearly 1,000 patients. Though the use of limbus stem cells is not as old as haematopoietic stem cells, about 1,500 patients with corneal damage have been treated so far; there is also sufficient evidence to prove its safety. Hence, there is a compelling reason for the ICMR and the DBT to apply the same yardstick and correct the anomaly. Though belated, the decision to call all the untested “therapies” offered to gullible people as clinical trials is indeed commendable.

Stem cell registry 30-12-2014 Stem cell registry will make cancer treatment cheaper • India may soon have an official database on stem cell donors & recipients • The health ministry is evaluating a proposal along with AIIMS to create a donor registry as part of the National Health Mission (NHM) • The proposal suggests enrolling all district hospitals in the first phase to seek stem cell details from across the country • Once a stem cell donor registry is in place, a willing donor can be contacted & can be coordinated easily • Apart from the donor registry, the ministry is also looking at creating facilities for human leucocyte antigen (HLA) typing (HLA-typing is a process conducted for matching donors & recipients of stem cell. HLA-typing is necessary to minimize rejection of stem cell transplant) • Normally there is 25% chance of a patient finding a matching donor within the family. The rest depend on unrelated voluntary stem cell donors • Stem cell therapy has been shown to be effective in various blood disorders & in treatment of cancer. It is widely used in bone marrow transplantation • However, stem cell treatment remains expensive because of limited research as well as unavailability & lack of coordination between donors & recipients • On an average, stem cell treatment is estimated to cost around Rs 15-16 lakh • the idea behind including stem cell into NHM is to make it affordable by creating records & providing facilities

Biotechnology Regulatory Authority of India (BRAI) Bill 2013 What is Biotechnology Regulatory Authority of India:- a proposed regulatory authority to regulate the research, transport, import, manufacture and use of organisms and products of biotechnology.

Why we need Biotechnology Regulatory Authority of India:- because India has signed “US convention on biodiversity” and “Cartagena protocol on Bio-safety ” which make regulatory authority necessary.

Current status: Currently biotechnology is regulated by “Ministry of Environment and Forests” and “Department of Biotechnology” under “Ministry of Science and Technology”.

Highlight of bill: • set up an independent authority . • regulate products and processes of Biotechnology and certify that the product is safe. • Doesn’t specify for any liability, the tribunal and the court will decide the liability. • Field trials of the modified products will only be conducted after permission from BRAI. • For a drug or vaccine with elements of biotechnology, the Central Drugs Standard Control Organization (CDSCO) will forward the application to BRAI to assess whether it is safe to proceed with a clinical trial.

Technology Page 50 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

BRAI Units:- • Risk Assessment Unit (RAU): The RAU will undertake science based safety assessments of the applications. • Product Rulings Committee (PRC): The report of the RAU will be forwarded to the PRC and the PRC will make recommendations regarding the safety of the product or organism. • Environmental Appraisal Panel (EAP): BRAI may refer an application to the EAP, in case of products or organisms having an environmental impact.

Opposition :- • The states are objecting that Center is trying to interfere in state right because the Bill brings the regulation of biotechnology under the powers of the center. The Centre claims that the states still have the powers in issues like GM technology as agriculture belongs to the State list. • The bill bypasses the RTI under the garb of being “Confidential Commercial Information”. • Conflict of Interest: this bill seen as a quick one-stop clearing house to benefits GM corporations as a committee of just 5 scientists will be empowered to clear the patented technology for use in whole country

GM plants 22 March 2014 07:47 Berg Visualizing Environmental Science 2014-362, Foundations in Microbiology 2015-307,

GM plants (transgenics)

• A gene is a unit of heredity that defines a trait or characteristic through the DNA code. In other words, it is a blueprint which determines the unique characteristics of plants, animals and micro-organisms • The technology driven modification of genes is called genetic modification, also called genetic engineering • Genetic modification has the ability to transform plants with specific characteristics, for example: pest or infection resistant, altered nutrients, high yielding crops that can grow in different climates or better flavour & taste • Plants with favourable characteristics have been produced for thousands of yrs by conventional breeding methods. Desirable traits are selected & the process is long taking up to 15 yrs to produce new varieties or hybrids • However, Genetic engineering not only allows this process to be dramatically accelerated but also in a highly targeted manner. Such plants are also called transgenic plants

Uses of GM plants • New generation GM crops are now being developed for production of medicines, vaccines, plastics & biofuels • Concerns of GM plants • There are concerns about biosafety, environmental safety, biodiversity loss & human & farm animal health • GM plants could make higher levels of toxic substances, may also be immunogenic

Way ahead • India needs to actively promote & involve public-private partnership (PPP) model in GM crop technology • GM foods must be tightly regulated by govt bodies • Scientists must conduct long term safety studies on human & environmental health before introducing it in the food supply

Cartagena Protocol on Biosafety

• It is an international agreement on biosafety, as a supplement to the Convention on Biological Diversity • The Biosafety Protocol seeks to protect biological diversity from the potential risks posed by genetically modified organisms resulting from modern biotechnology • The Biosafety Protocol makes clear that products from new technologies must be based on the precautionary principle & allow developing nations to balance public health against economic benefits • It will for example let countries ban imports of a genetically modified organisms if they feel there is not enough scientific evidence that the product is safe & requires exporters to label shipments containing genetically altered commodities such as corn or cotton • The Protocol entered into force on 11 September 2003. As of March 2015, the Protocol has 170 parties (103 signatories), which includes 167 UN member states, Niue, the State of Palestine, & the EU • The Protocol promotes biosafety by establishing rules & procedures for the safe transfer, handling, & use of LMOs, with specific focus on transboundary movements of LMOs (Living modified organisms)

10-10-2013 • GMO got implemented in 1996 • On one hand, we have WHO, the American Medical Association, the US National Academy of Sciences, the British Royal Society, & every other respected organization that has examined the evidences, airing the same conclusion: ‘that consuming foods containing ingredients derived from GM crops is no riskier than consuming the same foods containing ingredients from crop plants modified by conventional plant improvement techniques’

Technology Page 52 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

containing ingredients from crop plants modified by conventional plant improvement techniques’ • On the extreme other we have advocacy groups like Greenpeace, World Wildlife Fund, Organic Consumers Association, & Center for Food Safety showing concerns that potential risks to health & the environment relating to GM have not yet been adequately investigated

Nov 2013 Organic Farming Vs GM Crops • Organic farming is needed for sustainable and natural growth of agriculture in the future rather than going for genetic modified (GM) technology says renowned environmentalist Vandana Shiva. • Organic farming, in a way, fulfils every one of the principles of Gross National Happiness. It respects cultural values and promotes protection of the natural environment, whereas genetic modified crops destroy the natural web of life, threaten biodiversity and the environment, and are a scourge for human health and society. • Organic farming promotes biodiversity in the ecosystem

22-02-2014 Scientific evaluations of GM crops • Former PM backed the careful use of biotechnology to deliver high-yield crops resistant to weather, parasites & vectors • Fears about genetically engineered plants have been persistently disproved by science, whether the worry is about pesticide-resistant superweeds, or such plants contaminating their “natural” neighbours & eradicating biodiversity • The politics around GM crops has remained stubborn in India, even though the global movement is now running on fumes & there have been public recantations ○ Peer-reviewed scientific evidence is dismissed, every advocate of GM food written off as a corporate puppet, regulation pre-emptively declared untrustworthy, & selective “facts” marshalled by NGOs & taken at face value by many policymakers • Anxieties persist even though India has been a big biotech beneficiary during the Green Revolution ○ Bt cotton has converted India into a cotton-exporting country • What is needed is comprehensive, case-by-case study of each GM crop • Given the rising demands of food security & the promise of GM, it is important that the debate shift to one about optimal regulation

25-02-2014 Regulating genetic modification • Need to come up with new Biotechnology Regulatory Authority Bill in Parliament Agricultural Biotechnology Committee • submitted its report early in 2004 • It had recommended a Parliament approved regulatory agency as well as the necessary infrastructure for conducting all India coordinated trials with GMO • The necessary precautions, such as the needed isolation as well as demonstration of the importance of refuge, should be undertaken Analysis • The present moratorium on field trials with recombinant DNA material is a handicap as well as a disincentive in harnessing the benefits of GMOs ○ Much of the work is done in various research organisations & universities to develop GMOs which resist biotic & abiotic stresses as well as improved nutrition which are committed to public good ○ Young scientists get discouraged coz of the lack of a clear official signal on the future of genetic modification Way ahead • There must be a trial & safety assessment system • Since agriculture is a state subject, State agricultural universities & State depts of agriculture should be involved in the design & implementation of field trials • It takes nearly 10 years time for a new variety to be ready for recommendation to farmers. Therefore, speed is important in organising field trials & getting reliable data on risks & benefits • Krishi Vigyan Kendras should have the capability of offering scientifically credible advice to farmers on GMOs • The academy should set up two committees — on the public understanding of science & the political understanding of science — on the pattern of such committees set up by the Royal Society of London Public-private partnership in R&D

Technology Page 53 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Public-private partnership in R&D • The return from investments in biotechnology research is very high ○ Eg. Bt cotton research might have resulted in a profit of over Rs.50,000 crore, as compared to the total expenditure of about Rs.100 crore in such research • Public sector institutions should concentrate on the development of high yielding & disease resistant varieties, while obviously the private sector will only produce hybrids whose seeds will have to be brought every yr by farmers • Hence, a joint strategy by public & private sectors will help to ensure the inclusiveness of access to improved technologies among all farmers Promoting genetic engineering research • Recombinant DNA technology should be resorted to only when there is no other way of achieving the desired breeding goal while selecting projects for research Disseminating information • Media resource centres should be set up to give up-to-date scientific information to media representatives • Village knowledge centres should be utilised for spreading correct information on GMOs

25-02-2014 A case for GM plants • Genetic engineering in agriculture raises more concerns unknown in other applications of molecular technology ○ In pharmaceuticals, medicine & industrial applications, recombinant DNA technology has been widely accepted as providing useful tools • Though associated with wealthy economies historically, GM crops grown in “developing countries” in 2012 exceeded total acres grown in the so-called developed countries for the first time ○ India was the 16th country to approve a GM crop: Bt cotton in 2002 ○ Controversy over India’s second Bt crop — brinjal — was intense • We regularly take some risks coz of expected benefits, or coz the risk of doing nothing is higher ○ Ideally, regulation of any technology would reach some threshold of acceptable risk — balanced with benefits — for a whole society ○ For agricultural biotechnology, the precondition for risk regulation would ask of science: do GM plants produce more hazards than cultivars bred by other means? ○ The Directorate-General for Research assessed available regulatory science for environmental & food-safety risks in A Decade of EU-funded GMO Research (2001-2010): “The main conclusion to be drawn is that biotechnology, & in particular GMOs, are not per se more risky than conventional plant breeding technologies” • Like China & Brazil, India supported biotechnology for its potential benefits & established institutions of state science to assess risks ○ Bt cotton utilised an insecticidal protein derived from a common soil bacterium, Bacillus thuringiensis, hence “Bt”, to control pests in cotton with less pesticide; the results dramatically demonstrated benefits ○ The same technology applied to brinjal raised the risk bar coz it is a food crop . The Genetic Engineering Approval Committee (GEAC), after 9 years of tests involving 7 govt agencies & depts, approved release of the crop by both the private & public sectors, based on comparative assessment of options . No hazards from the insecticidal protein were found through standard safety protocols; GEAC findings conformed to the EU’s general conclusions . But then minister for environment, concluded that the GEAC studies were inadequate; risks to food safety & the environment were not done • The level of cautionary restriction should be not too much, not too little, but just right ○ Excessive regulation is suffocating & adverse to equity. Too little precaution might produce hazards that entail unacceptable risk • With climate change continually producing new challenges to agriculture, GM plants might be an important tool to fight it

17-03-2014 GM in EU • The regulations in the EU are restrictive coz they assume that GM technology is an inherently risky process • However, it is fair to say that over the past 20 yrs there has not been a single, scientifically valid piece of evidence suggesting that GM is any more dangerous than conventionally bred food crops

• Like China & Brazil, India supported biotechnology for its potential benefits & established institutions of state science to assess risks • Bt cotton utilised an insecticidal protein derived from a common soil bacterium, Bacillus thuringiensis, hence “Bt”, to control pests in cotton with less pesticide; the results dramatically demonstrated benefits • The same technology applied to brinjal raised the risk bar coz it is a food crop ○ The Genetic Engineering Approval Committee (GEAC), after 9 years of tests involving 7 govt agencies & depts, approved release of the crop by both the private & public sectors, based on comparative assessment of options ○ No hazards from the insecticidal protein were found through standard safety protocols; GEAC findings conformed to the EU’s general conclusions ○ But then minister for environment, concluded that the GEAC studies were inadequate; risks to food safety & the environment were not done

19-03-2014 Field trials are necessary to generate biosafety data

Concerns • Since these modified plant species are of relatively recent origin, data on biosafety are still not accepted as conclusive or comprehensive • The question of their superiority over hybrids is also a matter of debate • Transgenic seeds can contaminate a food chain • From the farmers’ perspective, there is fear of commercial monopolies in agriculture ○ Many times GM crops are linked to IP rights or commercial contracts, restrictions on use & the prospect of litigation come into play ○ This is an important dimension in India, which has a large number of small farms • While the GM foods industry claims transgenic plant varieties are safe on the one hand, but fiercely opposes labelling of products as such Situation • The UPA govt has in its last days permitted field trials of GM food crops • The Biotechnology Regulatory Authority of India Bill, 2013 lapsed ○ The report of the Parliamentary Standing Committee on Science, Technology & Environment on the legislation is awaited • At least 18 different varieties of GM crops including rice, wheat, maize, sugarcane & vegetables are officially in the pipeline Way ahead • The key questions while considering grant of permission for their production is their impact on health & the environment • the farming community must also be given a hearing • Scientific assessments must be independent of the proponents of GM agriculture, notably commercial entities • Need for instituting a robust regulatory mechanism before permission is granted for GM plants • It is equally vital that in a country with a diverse agricultural heritage, traditional seed varieties are not wiped out by monoculture • GM foods should not be allowed without full scientific evaluation on its long-term effects on soil, production & biological impact on consumers •

22-03-2014 GEAC reapproves GM crop field trials • Genetic Engineering Appraisal Committee (GEAC), the statutory appraisal arm of the Environment Ministry revalidates field trials for 10 varieties of GM plants including rice, wheat, maize, cotton & sorghum • India's 1st GM food, Bt brinjal, produced by the Maharashtra Hybrid Seeds Company Limited • Companies applied for revalidation after their earlier permits lapsed following opposition from States The revalidations would have to be first approved by the Union Environment & Forests Minister & then the

○ The revalidations would have to be first approved by the Union Environment & Forests Minister & then the promoter companies would have to go back to the States for a final nod • There are nearly 50 applications pending before the GEAC for first-time appraisal of GM crops, including several food crops • It provides hope to major promoters (multinational & Indian) of GM crop technology Before • Before Union Environment Minister had taken the view that it was not prudent to go ahead with the trials while the Supreme Court was hearing a case on the subject of field trials & the regulatory regime for GM technology in India • This decision was changed arguing that SC had not explicitly ordered any stay against clearing field trials while the case went on • > 100 food crop trials are in the pipeline, in various stages of development

16-04-2014 ‘GM crop adoption needs more trials & a stronger approval regime’ • GM crops required more research work & stronger approval regime ○ Instead of blindly opposing it, more research work should be allowed in terms of number of trials . Work on science must happen as well as efforts should go to strengthen approval protocols ○ This especially is needed in the wake of claims that the GM crops were more resistant to the vagaries of climate change & higher productivity benefits • There was a serious challenge in creating the knowledge & know-how among the farmers about the importance of GM food crops

21-07-2014 Env Min clears 15 trials for GM plants • The Environment Ministry gave its approval for field trials of certain varieties of GM crops, after the GEAC cleared 15 such proposals Backlog of proposals • The GEAC had a backlog of about 70 proposals seeking filed trials & has now cleared about 60 of those till March 2014 Transparency in regulatory process • One ethical conflicts is that proponents of GM crops are funding research in agricultural universities • To aid transparency, research findings should be made available in the public domain for independent study • Central govt has not permitted the commercial cultivation of Bt brinjal in India ○ The GM variety should be isolated from indigenous ones to prevent genetic contamination ○ If GM food is allowed to be sold to consumers, they must have the right to know what they are buying, & labelling should be made mandatory • There is no consensus on the performance of GM crops & the results have been mixed ○ They have had some beneficial impact on tillage practices & in terms of curbing the use of insecticides, but as the Union of Concerned Scientists in the US points out, they have created monocultures & may be affecting birds & bees ○ All this underscores the need for scientific inquiry, scrutiny & better regulation ○ Enacting a comprehensive law that covers all aspects of GM crops should be a priority

29-07-2014 Entry of Bt cotton • The public debates on GM began with the unannounced entry of Bt cotton in , where the farmers had grown 21,000 acres of Bt cotton Concerns of GM crops • Many argue that GM biotechnology stunted diversity, disempowered the farmer & skewed intellectual property rights in favour of MNCs ○ For centuries, farmers had been custodians of seeds but now they had to obtain seeds from institutions & MNCs (private) ○ Farmers should be free to choose the kind of farming & the seeds he wants to pick • Many also argue that if science was public knowledge devoted to creating public goods, it should be subject to a public debate This required that transparency & responsibility be built into every stage

Technology Page 56 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

○ This required that transparency & responsibility be built into every stage ○ Can private science work for public benefit, & who decides? ○ The questions of food chains, seed prices, contamination, & intellectual property should also be debated • Ecological science seems to suggest that GM biotechnology is not the only solution to agricultural problems

24-09-2013 • GM crops area under cotton cultivation in India is approx. 12 million hectares (of which 90% is under Bt cotton)

22-11-2014 Field Trials • Central Govt had written to certain states to allow field trials for GM crops. The Genetic Engineering Appraisal Committee (GEAC) has permitted field trials for more than a dozen crops but field trials can take place only if the state concerned gives an NOC Permission for GM mustard • BJP-ruled states of Madhya Pradesh, Rajasthan & Haryana have not given no-objection certificates (NOCs) for open field trials of transgenic hybrid mustard despite GEAC under Union environment ministry allowing these trials • These states argue that there is no credible & irrefutable evidence about GM crops not having adverse impact on humans/animals, biodiversity & environment • Also the GM mustard hybrids have been developed not by a Monsanto or a DuPont, but by Indian scientists • bio-safety research “level-1” trials have showed 30% higher yield potential over existing varieties. Now states withholding Level 2 trials • While states are entitled to block commercial planting of GM crops through denial of seed licences, they cannot be given a veto over field trials • It is for the GEAC to determine whether a particular transgenic is safe to be released for large-scale cultivation by farmers • crop biotech & recombinant DNA technology research have a great role in India’s agricultural future • Denial of NOCs for GM mustard & also a transgenic pod borer-resistant chickpea (developed by the Assam Agricultural University under PPP) is unfortunate as India is heavily import-dependent on these crops • India annually imports over $10 billion worth of edible oil & $2 billion of pulses • Mustard is India’s largest oil-bearing crop, while half of its pulses output comes from chickpea

08-12-2014 • US & China are bullish on GM crops. Europe was strictly against them. But the Lisbon Protocol was a step towards a more nuanced formulation • India has been in the middle. Its legislation on producers’ rights & environmental clearance by the empowered committee on a case-by-case basis is unique Success of GM crops in India • GM cotton has powered the growth of Gujarat’s agriculture in the last decade • Gujarat Agricultural University developed a GM maize variety with higher yield & was encouraged to cultivate in Adivasi regions & experienced good success. Maize success story has been repeated in north Bihar also

• ICAR scientists have developed high yield variety of pulses (GM Chicken Pea) but permission for its field trials are withheld by states • Improving the yield of pulses to 2 tonne per hectare is essential to overcome the nutrition & food-inflation barrier

06-01-2015 Bt cotton not to blame for farm distress: scientists • With GM plants, we could be extracting oil from leaves, instead of seeds. But unfortunately, it is caught up in a debate taken up by the Left & now supported by the neo-right • In the recent past, there had been a sharp increase in the acreage of GM crops in the country ○ over 90% of the cotton cultivated was GM crop • Scientists refuted arguments about monopolisation & noted that there were > 1000 Bt Cotton hybrids available in the country • Project Sunshine in Gujarat where Bt Cotton has powered the growth in agriculture • GM Maize has taken nutrition to Adivasi farmers

• The need of the hour was more of confined field trials. There will be no trust among the people if there is not enough data for analysis • Scientists said the ambiguous policy relating to GM crops had caused disillusionment & it was keeping young researchers from venturing into the field • Indian scientists have created a gene bank with over 4 lakh samples & has been acknowledged as one of the best biodiversity programmes in the world • Bt cotton has doubled cotton production & have reduced the load of pesticides. India is now exporting cotton worth $3 billion • there is a need for post release monitoring system of GM crops • India can also choose an alternative course of action if it did not want GM crops. For eg., Europe is investing hugely in new generation pesticides (we are still using old pesticides)

31-01-2015 Maharastra govt clears trials for GM crops

• Maharashtra govt has granted no-objection certificates for open field trials in genetically modified lines of rice, chana (chickpeas), maize, brinjal & cotton • With this decision, Maharashtra has become the 4th state after Punjab, Delhi & Andhra Pradesh to approve open field trials in GM crops • Gujarat, Rajasthan, MP, Chhattisgarh & Haryana are among those states who have denied permissions for such field trials, apart from Bihar, WB, Orissa, TN & Kerala • The Genetic Engineering Appraisal Committee under the previous UPA Environment Ministry had permitted field trials in the above transgenics. But it had inserted a condition requiring separate NOCs from states for such trials

02-02-2015 India world’s 4th in GM crop acreage

• India has the 4th largest area planted under GM crops, according to the International Service for the Acquisition of Agri-Biotech Applications (ISAAA) • ISAAA, a New York-based crop biotech advocacy group, has estimated the total global area under GM crops to have touched 181.5 mh last year, up from 175.2 mh in 2013 • Since 1996, when farmers first commercially planted transgenics, the area under these crops has risen more than hundredfold from 1.7 mh to 181.5 mh • It represents the fastest ever adoption of any technology in agriculture • Farmers in India planted a total 11.6 million hectares (mh) under transgenics in 2014, behind the corresponding areas for Argentina (24.3 mh), Brazil (42.2 mh) & the US (73.1 mh) • The GM crop acreage in India far surpassed China’s 3.9 mh, while equalling that of Canada’s 11.6 mh ○ Significantly, the entire 11.57 mh GM crop area in India in 2014 consisted of Bt cotton ○ Nearly 96% of the country’s cotton area is now covered by Bt hybrids Bt technology has helped India to treble its cotton output from 13 million bales in 2002 (when it was introduced)

○ Bt technology has helped India to treble its cotton output from 13 million bales in 2002 (when it was introduced) to 40 million bales in 2014 ○ In 2014, India overtook China as the world’s No. 1 cotton producer • While India’s GM crop acreage is wholly dominated by Bt cotton — much of it based on the US life sciences giant Monsanto’s proprietary “Bollgard” technology — this is not the case with other major countries ○ China had only 3.9 mh of GM planted area last year — almost fully under Bt cotton. But its govt has allowed commercial cultivation of 7 other crops — papaya, maize, rice, poplar, tomato, sweet pepper & petunia ○ Unlike India, where Monsanto enjoys a near monopoly, China’s GM crops have been developed largely by public sector research bodies ○ Moreover, China has sought to actively promote PPP model in GM crop technology Way forward • India needs to extend GM technology to more crops, & also encourage PPPs, so that our farmers benefit from competition & faster commercialisation • Granting of the rights for commercialisation of a Bt chickpea developed by the Assam Agriculture University to Sungro Seeds & that of the Indian Agricultural Research Institute’s Bt brinjal to Bejo Sheetal & Ankur Seeds are steps in the right direction

03-02-2015 Open field trials • The Genetic Engineering Approval Committee (GEAC) in the Union environment ministry had already approved trials in the case of 5 transgenic crops. State govts merely need to issue the NOC for these trials to go ahead • Any decision on commercialisation is for the Centre to take based on data pertaining to bio-safety & agronomic performance of the concerned GM plant lines • But the generation of such data is possible only through open field trials & hence, states should not be given a veto to ban field trials • The state's role should be limited to only issuing or denying seed licences

21-06-2015 Bt Cotton leading to suicides in rain-fed areas • The cultivation of Bt Cotton, a genetically modified, insect-resistant cotton variety, is a risky affair for Indian farmers practising rain-fed agriculture, says a latest study • Annual suicide rates of farmers in rain-fed areas are directly related to increase in Bt Cotton adoption, say the scientists • The study is significant for 2 reasons- ○ Most cotton cultivation in India is rain-fed ○ btw 2002 & 2010, the adoption of Bt Cotton hybrid went up significantly to 86% of the total cultivated area of cotton in India • Though cultivating the Bt Cotton variety may be economic in irrigated areas, the costs of the seed & insecticide increase the risk of farmer bankruptcy in low yield rain-fed settings • The study challenges the common assumption in economic analyses that cotton pests must be controlled to prevent monetary losses, thus encouraging Bt Cotton adoption

Recent whitefly epidemic in cotton crops of Punjab, Haryana

18-10-2015 • Recently whitefly attack in Punjab & Haryana, has raised concern among agricultural experts & farmers over the growing dependency on Bt cotton • But Bt cotton is effective against specific type of bollworms, but not insects such as whitefly • Need to focus on developing new technologies to fight pest infestation on cotton & other crops

23-10-2015 • Prior to Bt cotton’s introduction in 2002, farmers mostly grew public sector-bred varieties that were screened & certified for resistance against whiteflies or leaf curl virus ○ This system broke down when private-sector hybrids incorporating Bt genes took over > 90% of India’s cotton area Most hybrids were commercialised without any rigorous process of testing for whitefly or leaf curl virus

Technology Page 59 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

○ Most hybrids were commercialised without any rigorous process of testing for whitefly or leaf curl virus tolerance • Either way, Bt wasn’t the villain; these genes, in any case, control only for Heliothis or bollworm & not sucking pests such as whiteflies, aphids & mealybugs ○ Bollworm larvae were a huge menace during the 1980s & ’90s; the success of Bt cotton in controlling yield losses from them is well-established Lessons • The real lesson from the recent whitefly epidemic is that India needs a regime of compulsory registration & uniform certification of all seed varieties & hybrids, whether bred by govt or private enterprise • Only those meeting minimum standards relating to germination, purity & resistance to pests & diseases specific to the concerned crop should be allowed to be commercialised

Genetic Research 04 January 2014 19:06

23-02-2014

29-03-2014 Scientists create ‘designer’ chromosome Scientists have created the first man-made chromosome for a complex-celled organism — a feat hailed on Friday as a big step towards acquiring the controversial ability to redesign plants or animals

Test of success A synthetic chromosome was inserted into a brewer’s yeast cell, which functioned as normal — the key test of success, an international team reported in the journal Science. “Our research moves the needle in synthetic biology from theory to reality,” said Jef Boeke, director of New York University’s Institute for Systems Genetics and a member of the research team. Yeast is a closely-studied representative of the group of eukaryotes — organisms with complex cells that contain a nucleus and other structures enclosed within membranes. All plants and animals, including humans, have eukaryotic cells Yeast is used to make beer, biofuel and medicines, and researchers believe it can be made to work more efficiently with genetic modifications Chromosomes have previously been synthesised for bacteria, which are simpler, prokaryotic organisms

Altered chromosome Mr. Boeke and his team unravelled the coding of one of yeast’s 16 chromosomes, then used software to make changes to it, removing repetitive and less-used regions. They then built a synthetic version of this altered chromosome from scratch, stringing together individual nucleotides — the chemical building blocks of the genes that make up chromosomes, which in turn comprise the genome. “It is the most extensively altered chromosome ever built,” said Mr. Boeke. “We have made over 50,000 changes to the DNA code in the chromosome and our yeast is still alive. That is remarkable”

Yeast shares about a third of its 6,000 genes — units of the chromosome that carry the instructions for cell function — with humans. “Their effort represents a critical step on the road to building an entire eukaryotic genome,” said a media summary from Science. “It could also help researchers learn more about genome biology, including how genomes are

summary from Science. “It could also help researchers learn more about genome biology, including how genomes are built, how they’re organised, and what makes them work.”

Towards complete synthesis Mr. Boeke and his team are already working on synthesising other yeast chromosomes. This, they wrote, “represents a major step towards the design and complete synthesis” of a eukaryotic genome. “Rapid advances in synthetic biology coupled with ever decreasing costs of DNA synthesis suggest that it will soon become feasible to engineer new eukaryotic genomes, including plant and animal genomes with synthetic chromosomes encoding desired functions and... properties based on specific design principles.” Greenpeace scientist Janet Cotter said genetically modified organisms could be useful, in drug development for instance, but in controlled conditions. “In contained use, on a small scale in a lab, it’s absolutely fine. In a commercial situation, on a scale say for biofuels, you run into problems about how you adequately and securely contain those organisms.”

26-07-2014 < 10% of human DNA useful: scientists • > 90% of human DNA is doing nothing very useful, & may be no more than biological baggage that has built up over years of evolution • Researchers have known for some time that only 1% of human DNA is held in genes that are used to make crucial proteins to keep cells alive & healthy • This latest study suggests that a further 7% of human DNA is equally vital, regulating where, when, & how genes are expressed

24-02-2015 The genetic “library of life” • It is being created by a global community of scientists • This catalogue has already begun to help decode the genetic basis of certain cancers, heart disease & schizophrenia • We have only scratched the surface & discoveries require studying huge samples for every major disease • The Global Alliance for Genomics & Health comprising 246 organisations in 28 countries including India is one such endeavour to create a critical mass of data • The costs of genome sequencing have dropped drastically. While mapping a single human genome (as part of the Human Genome Project 1990-2003) costs $3 billion, today it costs less than $ 3,000 • This breakthrough opens up enormous opportunities to understand diseases (genomic medicine) • The data should remain shareable with the patients with their privacy protected

25-02-2015 • On April 25, 2003, a group of geneticists representing 6 countries announced that it had mapped every 1 of the 3 billion letters making up the human genome ○ What had taken scientists of the Human Genome Project 13 years and $3 billion to achieve can be done today for $3,000 ○ With thousands of human genomes now sequenced, the world, in just 5 years could have a complete catalogue for most of the important diseases • Genomic research has shown significant promises in targeting cancer, heart disease & schizophrenia • India should be one of the models in studying genetic variation & how it relates to disease ○ India is perhaps the single most 'interesting country' in terms of genetic diversity ○ There are restrictive regulations over sharing DNA out of the country. It is an obstacle for international collaboration ○ While genetic information could be misused, there should be laws tp prevent this ○ The access must be restricted to scientific use & the patients should have the right to share their data if they want to

Genome-editing technology

Crispr-Cas9 genome editing technique

Technology Page 62 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Crispr-Cas9 genome editing technique

• A specific sequence of guide RNA could be made to attach to a spot virtually anywhere on the genome, & the Cas9 protein would cleave the DNA at that spot. Then pieces of the DNA could be deleted or added, just as a film editor might cut a film & splice in new frames

22-04-2014 Revealed: Scientists ‘edit’ DNA to correct adult genes and cure diseases A genetic disease has been cured in living, adult animals for the first time using a revolutionary genome-editing technique that can make the smallest changes to the vast database of the DNA molecule with pinpoint accuracy.

Scientists have used the genome-editing technology to cure adult laboratory mice of an inherited liver disease by correcting a single "letter" of the genetic alphabet which had been mutated in a vital gene involved in liver metabolism.

A similar mutation in the same gene causes the equivalent inherited liver disease in humans - and the successful repair of the genetic defect in laboratory mice raises hopes that the first clinical trials on patients could begin within a few years, scientists said.

The success is the latest achievement in the field of genome editing. This has been transformed by the discovery of Crispr, a technology that allows scientists to make almost any DNA changes at precisely defined points on the chromosomes of animals or plants. Crispr — pronounced "crisper" — was initially discovered in 1987 as an immune defence used by bacteria against invading viruses. Its powerful genome-editing potential in higher animals, including humans, was only fully realised in 2012 and 2013 when scientists showed that it can be combined with a DNA-sniping enzyme called Cas9 and used to edit the human genome.Scientists have used the genome-editing technology to cure adult laboratory mice of an inherited liver disease by correcting a single "letter" of the genetic alphabet which had been mutated in a vital gene involved in liver metabolism.

A similar mutation in the same gene causes the equivalent inherited liver disease in humans - and the successful repair of the genetic defect in laboratory mice raises hopes that the first clinical trials on patients could begin within a few years, scientists said.

Since then there has been an explosion of interest in the technology because it is such a simple method of changing the individual letters of the human genome — the 3 billion "base pairs" of the DNA molecule — with an accuracy equivalent to correcting a single misspelt word in a 23-volume encyclopaedia.

In the latest study, scientists at the Massachusetts Institute of Technology (MIT) used Crispr to locate and correct the single mutated DNA in a liver gene known as LAH, which can lead to a fatal build-up of the amino acid tyrosine in humans and has to be treated with drugs and a special diet.

The researchers effectively cured mice suffering from the disease by altering the genetic make-up of about a third of their liver cells using the Crispr technique, which was delivered by high-pressure intravenous injections.

Technology Page 63 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

"We basically showed you could use the Crispr system in an animal to cure a genetic disease, and the one we picked was a disease in the liver which is very similar to one found in humans," said Professor Daniel Anderson of MIT, who led the study.

"The disease is caused by a single point mutation and we showed that the Crispr system can be delivered in an adult animal and result in a cure. We think it's an important proof of principle that this technology can be applied to animals to cure disease," Professor Anderson told . "The fundamental advantage is that you are repairing the defect, you are actually correcting the DNA itself," he said. "What is exciting about this approach is that we can actually correct a defective gene in a living adult animal."

Jennifer Doudna, of the University of California, Berkeley, who was one of the co-discoverers of the Crispr technique, said Professor Anderson's study is a "fantastic advance" because it demonstrates that it is possible to cure adult animals living with a genetic disorder.

"Obviously there would be numerous hurdles before such an approach could be used in people, but the simplicity of the approach, and the fact that it worked, really are very exciting," Professor Doudna said.

"I think there will be a lot of progress made in the coming one to two years in using this approach for therapeutics and other real-world applications," she added.

Delivering Crispr safely and efficiently to affected human cells is seen as one of the biggest obstacles to its widespread use in medicine.

Feng Zhang, of the Broad Institute at MIT, said that high-pressure injections are probably too dangerous to be used clinically, which is why he is working on ways of using Crispr to correct genetic faults in human patients with the help of adeno-associated viruses, which are known to be harmless.

Other researchers are also working on viruses to carry the Crispr technology to diseased cells - similar viral delivery of genes has already had limited success in conventional gene therapy.

Dr Zhang said that Crispr can also be used to create better experimental models of human diseases by altering the genomes of experimental animals as well as human cells growing in the laboratory.

Professor Craig Mello of the University of Massachusetts Medical School said that delivering Crispr to the cells of the human brain and other vital organs will be difficult. "Crispr therapies will no doubt be limited for the foreseeable future," he said

19-03-2015 Is ‘editing’ human embryos ethical? • a group of scientists has raised ethical & safety concerns over genetically editing human embryos • They hint that the method has the potential to create that eugenically worrisome concept of the designer baby using specific genes for greater intelligence or specific physical attributes such as blue eyes • Genome-editing technology does offer promising tools to correct disease-genes by snipping away harmful mutations to possibly treat human diseases such as HIV/AIDS, haemophilia, sickle-cell anaemia & forms of cancer • But when genetic manipulation targets sperms & eggs (the germ line), the changes can be inherited, opening up an array of ethical, legal and health concerns ○ Such research, could be exploited for non-therapeutic modifications ○ Scientists should not agree to modify the DNA of human reproductive cells & a voluntary moratorium in the scientific community could be an effective way to discourage human germline modification ○ Using genome-editing to manipulate germ cells, could undermine genetic interventions to treat serious debilitating diseases

Researchers can cut & paste DNA into just about any animal, plant or fungus • A technique called “gene drive” ensures a modified gene will be inherited with nearly 100% success ○ This is valuable in making sure that a desirable new gene, like one resistant to the malaria parasite, spreads once introduced into a mosquito population ○ It also means a mistake can’t easily be taken back Analysis • As scientists, policy makers & citizens, we need to start debating how much genetic tinkering we should allow in the wild & what regulations need to be in place • These new tools could help us cope with many risks to humans & animals, including climate change ○ Coral could be buffered against warming ocean water through the introduction of heat-tolerant genes ○ Genes from successful species could be used to help rescue imperiled ones ○ It can help species adjust to our changed planet more quickly than they could on their own • But the ecological risks of these manipulations are real & poorly understood ○ We can’t fully predict the consequences of releasing self-propagating genes into the wild ○ Encoding a self-destruct gene (for eg. by altering sex-determining genes so the population eventually ends up entirely male, could be a way to battle invasive species) . But such genes could potentially leak to places where these species actually play important ecological roles — & could even jump to other species through interbreeding .

Cloning & stem cell research 30 January 2014 17:11

iPS cells

• In 2006, showed to the world that reversing adult cells (differentiated cells) to behave like stem cells — induced pluripotent stem cells (iPS cells) — is indeed possible by introducing 4 transcription factors

13-09-2014 Japan first to implant iPS stem cells

A retina sheet prepared from iPS stem cells Japanese researchers conducted the world’s first surgery to implant ‘iPS’ stem cells in a human body in a major boost to regenerative medicine, two institutions involved said. A female patient in her 70s with age-related macular degeneration (AMD), a common medical condition that can lead to blindness in older peo ple, had a sheet of retina cells that had been created from iPS cells implanted.

31-10-2014 Scientists grow miniature human stomachs from stem cells Scientists have grown miniature human stomachs (Gastric organoids) from stem cells as a way of studying gastric diseases such as ulcers & stomach cancer & in the future creating tissue to repair patients’ stomachs. 'Organoids' • A year ago, group of researchers in Austria announced iPS cells (which behave similarly to embryonic stem cells, but are made from skin cells & thus do not require the destruction of human embryos) & coaxed them into differentiating & growing into objects known as organoids • An organoid is not a proper organ, but it resembles one in scientifically useful ways, both in the mixture of cells it contains and in its anatomical features Proof by induction • The process by which a fertilised egg turns into a complete animal, human or otherwise, is orchestrated by proteins called growth factors, which stimulate or suppress the functions of particular genes • Tweaking these, along with a few other chemicals (including retinoic acid that is important in lots of developmental processes) can guide stem cells down the right path to arrive at a particular tissue type Potential • Organoids can be used for creation of real organs inorder to replace the entire diseased or damaged body parts • They are an excellent way of improving medical testing, particularly by doing tests that have proved hard or impossible in the past (like to create a laboratory model of the interaction btw H. pylori & human stomach tissue & thus obviate the need to continue searching for an animal-based one)

Cloning

• Cloning (somatic cell nuclear transfer technique), where the nuclear matter from an adult cell is transferred into an egg whose nucleus has been removed

16-10-2014 Stem cells to treat blindness appear safe • In the new research, scientists turned stem cells into retinal cells to treat people with macular degeneration or Stargardt’s macular dystrophy, the leading causes of blindness in adults and children. • the stem cells survived years after the transplant and weren’t wiped out by the patients’ own immune systems.

09-05-2015 Scientists discover human marrow version in fruit fly • Scientists in India claim to have discovered a simpler version of the human bone marrow in the adult fruit fly, a finding with potential implications for advances in stem cell biology, immunity, treatment of blood-related disorders

finding with potential implications for advances in stem cell biology, immunity, treatment of blood-related disorders such as leukemia, wound healing & the study of ageing • The fruit fly presents the perfect model. It is a simple organism with all its 5,000 genes identified ○ Extracting human bone marrow is difficult & presents ethical issues, while studying the process in mice has its own complications ○ In the fly, you can mark & monitor each cell by colour-coding it, without having to dissect it

10-01-2016 Dr.Tilak HR Prospects of cloning & stem cell research

Fig: Stem cells (Left) that are not yet differentiated; nerve cells (Right) after differentiation, ready to perform specialis ed functions • First cloning was done on a frog in 1962 by John B Gurdon (UK) - He is also called the ‘Grandfather of Cloning’ • His contributions has laid the foundation for research which holds out the promise of tissue immortality to prevent disorders such as blindness & Parkinson’s disease • Gurdon got 2012 Nobel prize along with Japanese biologist Shinya Yamanaka • In 1962, Gurdon employed the cloning technique — transfer of nuclei from adult cells into eggs for generating embryonic cells • In recent times Shinya Yamanaka developed the 'Yamanaka procedure' which demonstrated that adult cells can be reprogrammed into their embryonic phase & further into new cell types (like blood, pancreas, heart cells etc.) ○ This procedure can be applied to humans ○ Among the disorders where this is ready to be tried is macular degeneration, a cause of blindness in the elderly . Damage to the retinal epithelium & photo receptor cells causes the blindness in this disease . It is possible to make replacement cells from the skin & transplant them underneath the photo receptors. This is shown to rescue the loss of cells

Display technologies

AMOLED (active-matrix organic light-emitting diode)

is a display technology for use in mobile devices & televisions. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels IPS (In-plane switching) is a screen technology used for liquid crystal displays (LCDs).

In-plane switching involves arranging and switching the molecules of the liquid crystal (LC) layer between the glass substrates essentially in a plane parallel to these glass plates TFT or Thin Film Transistor is used to improve readability of LCD panels and has fewer number of electrodes per pixel. Transistors are embedded within the panel itself, reducing crosstalk between pixels and improving image stability. Used mainly in entry-level handsets with colour screens, TFT displays boast of better image quality than LCDs LCD, or Liquid Crystal Display, is the most common flat panel display. It uses a combination of layers of liquid crystals and a backlight to produce an image. This type of display renders excellent colours on the screen but falls short of the competitors when it comes to contrast ratio Therefore, it is unable to match the darkness levels of other some screens like Super AMOLED and the colours seem washed out in sunlight IPS IPS, or In Plane Switching, is an evolution of the LCD, invented by Hitachi and LG to improve on colours and viewing angles of TFT displays. This type of panel outdoes TFTs by offering better viewing angles and colour rendering, thus allowing users to view the images on the screens at acute angles without any loss of quality Retina display Introduced by Apple, this type of LCD panels uses pixels smaller than the human retina can perceive. The pixel density of Retina displays is such that the human eye is unable to distinguish between individual pixels, contributing to a more enjoyable viewing experience. This type of display technology is found in iPhone 4S/5C/5S, iPad Air, second-generation iPad Mini, fifth generation iPod touch and 13- and 15-inch MacBook Pro OLED OLED or Organic Light Emitting Diodes, produce their own light rather than relying on a backlight, thus saving battery and rendering dark colours more effectively. It offers a brighter, more vivid picture with a higher contrast ratio on lower power consumption and is thinner and lighter than LCDs AMOLED AMOLED or Active Matrix Organic Light Emitting Diodes display panel is a spin-off of the OLED screens, wherein the all

AMOLED or Active Matrix Organic Light Emitting Diodes display panel is a spin-off of the OLED screens, wherein the all pixels are connected to tansistors and capacitors, which actively maintain pixel state at all times. This type of screen is cheaper to manufacture and consumes less power than standard OLED screens Super AMOLED Super AMOLED is just Samsung's way of marketing the OLED screens it manufactures, not a technical term when it comes to display panels. However, the manufacturing process differs from the method followed in developing standard AMOLED panels, as the touch-detecting layer is embedded in the screen itself, rather than being put on top of it. Samsung claims that Super AMOLED Screens reduce the amount of sunlight reflected by five times. The company develops Super AMOLED, Super AMOLED Plus, and HD Super AMOLED, differing upon the number of sub-pixels S-LCD Super LCD or S-LCD is a display panel manufactured by a subsidiary of Samsung, which was partly owned by Sony till recently. S-LCD panels use technology that brings quality and contrast levels to near-AMLED standards, but at a lower price Essentially, this display technology fares better than AMOLEDs in terms of colour definition but loses out by a whisker when it comes to vividness of images ClearBlack The strength of Nokia's ClearBlack display technology is its ability to block incoming light in order to reduce reflections and make the improve image quality, especially under sunlight. This display panel boasts of deeper blacks and better viewing angles than most of its competitors and is used in Nokia's Lumia phones E-Ink E-Ink displays had been confined to e-readers like Kindle & Kobo till now, even though Motorola and Samsung had experimented with them earlier. But a Russian manufacturer has launched YotaPhone, the world's first smartphone with an E-Ink display on the back and a LCD panel in front E-Ink panels do not display colours and are best known for not hurting the eyes even if you stare at them for long hours. This makes them perfect for reading e-books. They consume very less power and devices with E-Ink panels can operate for days on a single charge

LCD TVs vs LED TVs vs Plasma TVs

• an LED TV is also an LCD TV, as the screen on both is a liquid crystal display • An LCD display has two layers of glass that are polarized and joined together, the liquid crystals between the 2 layers then pass or block the light to display the television picture • On an LCD TV, the lamps at the back of the screen are fluorescent lamps, whilst on an LED TV the lights at the back of the screen are Light Emitting Diodes (LED)

Computer n Communication Technology Page 3 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• LED TVs generally have better black levels and contrasts than their LCD counterparts. Color accuracy is also slightly better on an LED TV • LED TVs are energy efficient than LCD TVs • LED TVs are slimmer compared to LCD TVs • LED TVs may create ghostly permanent images on the screen when used for a long time. This is what you call burn- in, which is less likely to happen with LCD TVs

• LCD panels are typically composed of two sheets of polarized material with a liquid crystal solution between them, so when an electric current passes through the liquid, it causes the crystals to align so that light can (or can’t) pass through. Think of each crystal as a shutter or gate, either allowing light to pass through or blocking it out. After passing through the frontmost polarized pane, the light then passes through a color filter that leaves it either red, green, or blue. Each cluster of red green and blue makes up one pixel on the screen. By selectively illuminating the colors within each pixel, a wide range of hues can be produced on the larger display • A plasma TV is sometimes called an "emissive" display — the panel is actually self-lighting • The display consists of two transparent glass panels with a thin layer of pixels sandwiched in between. Each pixel is composed of three gas-filled cells or sub-pixels (one each for red, green and blue). A grid of tiny electrodes applies an electric current to the individual cells, causing the gas (a mix of neon and xenon) in the cells to ionize. This ionized gas (plasma) emits high-frequency UV rays, which stimulate the cells' phosphors, causing them to glow the desired color

• Coz a plasma panel is illuminated at the sub-pixel level, light output is very consistent across the entire screen area. Plasmas produce the widest horizontal and vertical viewing angles available — pictures look crisp and bright from virtually anywhere in the room • Because plasma TV screens use a phosphor coating like CRT-based TVs, the possibility of screen burn-in exists

4K UltraHD TV

• 4K or 4096 x 2160 [or 3840 x 2160 for TVs (16:9 Ratio) ] pixels is 4 times the resolution & 4 times the number of pixels as compared to full HD (1920 x 1080 pixels)

HDD & SSD

Hard disk drive (HDD) is a data storage device used for storing & retrieving digital information using rapidly rotating disks (platters) coated with magnetic material A solid-state drive (SSD) (also known as a solid-state disk or electronic disk, though it contains no actual "disk" of any kind or motors to "drive" the disks) is a data storage device using integrated circuit assemblies as memory to store data persistently. SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks, which contain spinning disks and movable read/write heads.

Bits & Bytes Bit • Bit -- like an atom -- the smallest unit of storage • A bit stores just a 0 or 1 Everything in a computer is 0's and 1's ... what does that mean? The bit stores just a 0 or 1 .. it's the smallest building block of storage Byte • One byte = grouping of 8 bits • e.g. 0 1 0 1 1 0 1 0 • One byte can store one letter, e.g. 'b' or 'x' How much exactly can one byte hold? • How many distinct/separate patterns can be made with 1, 2, or 3 bits? • (Not hold you responsible for details, go through derivation) Number of bits Distinct Patterns 1 0 1 2 00 01 10 11 3 000 001 010 011 100 101 110 111 In general: add 1 bit, double the number of patterns • 1 bit - 2 patterns • 2 bits - 4 • 3 bits - 8 • Mathematically: n bits yields 2ⁿ patterns (2 to the nth power) So, One Byte - 256 Patterns (1 byte is group of 8 bits)

11-09-2014 Mobile phone numbers All mobile numbers are ten digits. What is the technical reason? In the world due to technical & user base reasons the mobile numbers at present varied from 10 to 11 digits. Due to technical reasons two countries, UK and China moved to 11 digits in mobile phone numbers. In India all mobile numbers have 10 digits under the govt’s National Numbering Plan (NNP) The number of digits in a mobile phone number describe the maximum mobile phones we can have without dialling the country code, that is 91 (for India). If we had a 9 – digit cell number, the maximum number of cell numbers possible

Computer n Communication Technology Page 5 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

country code, that is 91 (for India). If we had a 9 – digit cell number, the maximum number of cell numbers possible would have been 10 9 , ie. a maximum of 1000 million or 100 crore subscribers. Since our population is close to 125 crore, obviously we cannot have a 9- digit cell phone number. Adopting a 10– digits cell number offers a capacity to have 10 billion or 1000 crore subscribers and the total population would get at least one mobile number each. In 2003, the Department of Telecommunication ( DoT) In India had implemented the 10–digit mobile numbers which will meet the needs for 30 long years. On February 2009, India registered a user base of 375.74 million wireless subscribers. 10-digit numbers can cater to an additional 250 million users. Under the current 10-digit numbering scheme, only a maximum of 1 billion mobile numbers can be issued and the mobile phone connections in India would cross this mark in the next couple of years. DoT had previously proposed a transfer of numbers from10 -digits to 11- digits in January 2010. At present all mobile phone numbers are 10 digits long and the way to split the numbers is defined in the National Numbering Plan 2003 as XXXX – NNNNNN where XXXX is the Network operator, NNNNNN is the subscriber numbers

Internet 12 March 2014 20:48 Sociology MA-2287,

• Internet is turning our generation into global citizens

12-03-2014 Digital divide in terms of internet penetration: • In 2015, 81% of households in developed countries have internet access, but only 34% in developing regions & 7% in the least developed countries • North America- 80%, Europe- 67%, Asia- 27%, Africa- 15%, Middle East- 40%

Internet user-base in India

• Only 20% of India has internet access (ie. Around 80% of the Indian population does not have access) • India has one of the lowest internet-penetration rates & one of the highest mobile-internet gaps (difference btw number of mobile phone owners & those with internet) • The growth of Internet users has also led to a substantial growth of other digital industries such as e-commerce & digital advertising • The average Internet speed in India in 2014 is just 2 Mbps, compared to the global average of 4.6 Mbps • Around 45% of online users in India access internet only through their mobile phones • PM Modi said that digital connectivity is a basic right

10-10-2014 India likely to have 600 million mobile broadband users by 2020 • The mobile broadband subscriber base in India could grow to 600 million by 2020 from around 100 million now • Smartphone prices are expected to fall by 40-50% over the next 3 years • Mobile broadband can be the platform on which the ‘Digital India’ vision can be delivered • Operators in India have far less spectrum than their peers globally with high mobile broadband penetration ○ Spectrum will play a key role in driving mobile broadband growth in India in the long run, & will be an increasingly important driver of capacity, user experience, & quality • It said operators will need access to more spectrum from the govt, & will need to build new network capabilities & new revenue models

08-05-2015 Internet usage: India 3rd with 300 mn users but lags in speed • Internet users reach 300 million & Internet penetration is roughly 20% • India has the 3rd largest number of Internet users in the world behind China & the US • But India lags in terms of average broadband speed & penetration • India had a wired internet speed of 1.7 mbps while wireless was 1.3 mbps • But India ranked 125th in the world for fixed broadband penetration, lagging behind Bhutan & Sri Lanka in terms of fixed & broadband penetration in 2013, according to the Broadband Commission of the International Telecommunication Union & UNESCO

the least developed countries • North America- 80%, Europe- 67%, Asia- 27%, Africa- 15%, Middle East- 40%

Urban-rural gap in usage • Out of 200 million Internet users, only 25 million are from rural India (but electorally, the weight of rural India is 75% or more) ○ A lot of voters were using the Internet to form their opinion on politicians & issues ○ Internet is poised to play a larger role in the elections ○ Internet could be a major factor in Indian politics as 600 million Indians are expected to be connected by 2019

18-04-2015 • India ranks 125th in the world for fixed broadband penetration. Bhutan & Sri Lanka are ahead of it in 2013, according to the Broadband Commission of the International Telecommunication Union & UNESCO • In the wireless or mobile broadband segment, India is ranked at 113th with a penetration of 3.2 per 100 citizens TRAI recommendations • To promote the use of fixed-line broadband, the licence fee on the revenues earned from fixed line should be exempted for 5 years • Encourage local & foreign companies to build data centre parks on the lines of industrial parks & SEZs • Make Wireless Planning Commission, the custodian of spectrum at Dept of Telecom (DoT), an independent body by delinking it from DoT & convert it into a statutory body • Audit spectrum usage to check for efficiency • Cable operators should be encouraged to take advantage of their network to provide broadband connections

07-10-2014 Why are internet connections so expensive in India? • The path of an email would traverse intercontinentally & adds up the cost • If there was fibre-optic cable underground infrastructure & a system of internet exchanges in India- that covered all our major cities, our email would have travelled locally through this fibre-optic channel & back, all within India • So, TRAI in 2010 recommended that a National Optic Fibre Agency be set up & at a cost of Rs 65,000 crores a fibre- optic network be laid across the country as a public utility • Since then, , to execute this plan, has come into existence & pilot projects have been undertaken • Similarly, a National Internet Exchange (NIXI) has come into being with traffic exchange points in the 7 largest cities in India • But still work towards it is unsatisfactory

16-02-2015 Bringing internet to more Indians • The -led Facebook got together with Anil Ambani’s to launch in India internet.org, a service that offers subscribers free access to a pre-selected bouquet of Websites • Google’s plan is to use helium balloons (project Loon) to connect people to the Net • Microsoft in 2014 announced a ‘white spaces’ project — a plan to use unused TV spectrum of Doordarshan & the govt to provide connectivity • India’s internet penetration is < 20%, whereas in China, Russia & Brazil it is nearly 50% • Google’s plan, more technologically audacious, is to use “a network of balloons travelling on the edge of space, designed to connect people in rural & remote areas, help fill coverage gaps, & bring people back online after disasters” • Interestingly, the govt itself is working on a mega plan to make internet ubiquitous in India with Digital India project Comments • More Internet is also good for a country’s GDP ○ A research study claimed that an 0.46 percentage point increase in the GDP of low- & middle-income countries when a 1% increase in broadband penetration is achieved • But more significantly, more Internet is good for the Internet companies, as Google’s revenues are positively correlated with the world’s Internet population ○ This makes sense for Internet companies to do everything to increases the size of the pool as also improve it Google Fiber, which seeks to provide “fiber-to-the-premises” at 100 times the broadband speeds of today, is one

○ Google Fiber, which seeks to provide “fiber-to-the-premises” at 100 times the broadband speeds of today, is one such. Facebook is said to be considering the use of drones & satellites to connect people • A recent Morgan Stanley report predicted India’s user base to exceed 600 million in 2020, which means 46% of the population would have been covered • 92% of internet consumption in India happens through mobile wireless (mobile + dongle)

2016 World Development Report - 'Digital Dividends'

14-01-2016 Dr.Tilak HR Digital dividends not spreading rapidly - World Bank • 60% of the world’s population still offline. Almost 1.063 billion Indians were offline even though India ranked among the top 5 nations in terms of the total number of Internet users • Institutional & regulatory barriers to efficiency are exacerbating the problem of low & unevenly distributed “digital dividends” from growing Internet penetration across countries • Although there are positive outcomes from a deepening digital economy in countries such as India, the automation of jobs in some cases was leading to inequalities in the labour market btw high-skill & low-skill workers • Although 40% of the world’s population is connected by the Internet, it is important to be mindful that we do not create a new underclass • With nearly 20% of the world’s population unable to read & write, the spread of digital technologies alone is unlikely to spell the end of the global knowledge divide • The report also cautioned that with the advent of big data, which includes the likes of India’s Aadhaar unique identity project, “secret snooping by govts can be for legitimate law enforcement reasons, but sometimes violates laws & rights, as the Edward Snowden revelations about spying by the security agencies of the US, the UK, & others have shown” • There are many examples of success stories worldwide where the power of the Internet had been leveraged to improve the delivery of public services ○ But the delivery of services through the Internet ultimately depends on the regulation of the service sector itself & India ia among the countries which has “the greatest restrictions on service trade” • A poor business climate and vested interests often hold back digital adoption. Among online firms, the economics of the Internet may enable natural monopolies to exploit their dominant position, hurting consumers & suppliers ○ Hence India needs to have an appropriate business environment, which shapes how firms adopt & use technology

It is a ‘path’ on which the web runs ○ It is not the internet. That is a hardware network made up of servers, fibre optic, microwave and comsats talking to each other in TPC/IP, a protocol designed by Robert E. Kahn & Vinton Cerf ○ The Web, which consists of interlinked data, rides on the internet. It is made up of electrons & talks to our browsers in HTML & HTTP, the mark-up language & transfer protocol written by Berners-Lee

14-03-2014 • It has created millions of new jobs supported by hitherto impossible business models, like the online bookstore, but it has also wiped out traditional ways of making a living, like bookselling • It has rekindled protest politics directed against authoritarian or unresponsive govt (Tunisia, India) • It also has sparked off a mini crime wave on the Dark Web, the part of the medium inaccessible to search engines & casual surfers, where drugs, guns, assassination contracts & child pornography enjoyed a flourishing market until a recent crackdown • The next wave of enterprise will be fuelled by unstructured data, which Big Data methodologies trawl in search of patterns which are not perceptible to the human intelligence but can be discerned by powerful computers processing data in bulk ○ The most valuable source of unstructured data is social media ○ However, in the near future, the volume of data being generated will go into overdrive as the Internet of Things takes off

17-03-2014 • After the invention of the printing press, this is the most defining development in the world of communication • Its impact is still growing & its full potential yet to be realised despite the many changes it has brought in its wake • In March 1989, a British scientist, Tim Berners-Lee, working at CERN, submitted a paper titled “Information Management: A Proposal” that gave birth to the World Wide Web • The Web has generated billions of dollars in economic growth, turned data into the gold of the 21st century, unleashed innovation in education & health care, whittled away geographic & social boundaries, revolutionised the media, & forced a reinvention of politics in many countries by enabling constant two-way dialogue btw the rulers & the ruled • Few principles allowed the web, as a platform & to support such growth ○ By design, the Web is universal, royalty-free, open & decentralised ○ Thousands of people worked together to build the early Web in an amazing, non-national spirit of collaboration; tens of thousands more invented the applications & services that make it so useful to us today ○ There is still room for each one of us to create new things on & through the Web

Internet from space

New battle • Although both Facebook & Google have said that they don’t want to become internet service providers • But when free Wi-Fi starts covering the globe in near future, traditional telecom service providers are bound to feel threatened • If you have Wi-Fi everywhere no one is going to use their services which shall lead to more regulatory battles ahead • This could even wipe out the entire telecom industry

Project Loon

• It is an affordable balloon-powered Internet • Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural & remote areas, help fill coverage gaps, & bring people back online after disasters • Project Loon balloons will travel in the stratosphere, approx. 20 km above the Earth’s surface, latching on to layers of wind as directed by software algorithms to determine where they need to go. In the end, they will form one large communications network • The inflatable envelopes are made from sheets of polyethylene plastic (15m wide & 12m tall when fully inflated) • They are designed to stay up for at least 100 days in one go • The electronics are powered by an array of solar panels • The small box under the balloon will contain circuit boards that control the system, radio antennas to communicate with other balloons & with Internet antennas on the ground • Each balloon can provide connectivity to a ground area about 40 km in diameter using LTE • Project Loon partners with telecom companies to share cellular spectrum • In June 2013, Project Loon was tested in New Zealand

Aquila

23-10-2015 • It is a solar-powered aircraft with a wide wingspan, that can stay up for months on end • Cruising altitude: around 18 km, much higher than commercial aircraft • Footprint: 100 km diameter • They will move, but around a small zone. When the plane moves the RF (radio frequency) system will adjust so that it continues to have the same terrestrial footprint • While these aircraft try & create a grid of connectivity, there will also be dark spots without connectivity in areas with no substantial population. Those areas could be fed by satellite

Internet.org

• Internet.org is a global Internet access initiative of Facebook & 6 other technology giants, namely Ericsson, MediaTek, Nokia, Opera, Qualcomm & Samsung, launched in 2013 which aims to bring the internet to 2/3rds of the world’s population that doesn’t have it

Computer n Communication Technology Page 11 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

world’s population that doesn’t have it • Sharing tools, resources & best practices, Internet.org partners will explore solutions in 3 major opportunity areas: affordability, efficiency, & business models ○ Affordability: developing technology that decreases the cost of delivering data to people worldwide ○ Efficiency: improve data compression capabilities and make data networks and services run more efficiently ○ Business models: introduce business models that give people more ways to go online

Jana

08-05-2015 • Jana, a Boston-based start-up, offers the emerging world free access to the Internet without violating principle • It launched Jana Loyalty, a product that seeks to reward its smart phone users in 2 ways ○ it reimburses users the cost of downloading & using an app of Jana's clients ○ it gives free additional data with which the user can access any content online • The free data can also be used however they choose; users can surf the web, download a new app, or watch a video • Instead of making Wikipedia or Facebook free for all, Jana wants to make the entire Internet more affordable to everyone & at the same time, make it less costly for people to explore fun & useful new apps • Jana's launch comes at a time when social media giant Facebook's attempts to provide a limited version of the Internet free has been attracting criticism from supporters of Net neutrality, especially in India

OneWeb

26-06-2015 • It is supported by a global consortium of Qualcomm, Virgin Group, Airbus, Coca-Cola, Intelsat & Grupo Salinas • It aims to provide affordable internet access to all • It aims to build a communications network with an initial constellation of 648 low earth orbit satellites that will provide connectivity around the world • The OneWeb User Terminals contain embedded LTE, 3G, 2G & Wi-Fi access capabilities that extend the reach of mobile operators • OneWeb satellites will provide high-speed connectivity to a small user terminal, which transmits broadband access through Wi-Fi, LTE, 3G & 2G to the surrounding area

Free-space optical communication

28-03-2014 • makes use of light to transmit data through space using invisible, infrared laser beams • is a promising technology that potentially allows to boost the speed of internet connections provided by satellites & drones • For lower density areas, low-Earth orbit & geosynchronous satellites can beam internet access to the ground

White-fi

14-07-2015 • White-Fi or television White-Space technology works like Wi-Fi on a bigger scale • It puts the unused spectrum in the TV channels to a good effect • This technology has potential to provide free connectivity to large sections of the Indian population through wider coverage & economical deployment & licence-free access • Low density of population & low-income group segments remain unattractive to commercial telecom providers, & in such a scenario, White-Fi technology can be best suited to provide digital connectivity

Internet addiction

08-06-2014 • Technology addiction or internet addiction is recognised by mental health professionals as akin to addictive disorders concerning drugs or alcohol. • It is the propensity to excessively engage in activities involving the cellphone, internet and social networking sites to the detriment of one’s health, social life or mental state. • Teenagers are particularly prone to the addiction, which manifests itself in acts like constantly checking instant messaging apps, frequently changing status messages and profile photos on social networks, and uploading selfies daily. • In many cases, the addiction leads to insomnia, depression and social withdrawal. • Experts say these cases are likely to be the tip of the iceberg in a country where smart phones and tablets are being adopted at a roaring pace. • Few de-addiction clinics are also practicing in India.

16-10-2014 • The existence of Internet addiction disorder linked to conventional devices such as phones and PCs is hotly debated among psychiatrists. Many researchers maintain that its effects are merely symptoms of other psychological problems. • It was not included as a clinical diagnosis in the 2013 update to the Diagnostic and Statistical Manual of Mental Disorders

Safe internet for children

31-03-2015 • In 2014, a survey done in India found that 30% of Indian children accessing the Internet have experienced some kind of cyber harm including cyber-bullying, cyber-stalking, hacking & defamation ○ The survey reveals that 34% of children rarely speak to their parents about their online activities ○ Researching for school & project work, social networking, downloading music & movies rank highest in their list of online activities • Online risks affecting children include cyber-bullying, identity theft & fraud, danger from online predators, & exposure to pornography or other inappropriate images • Fundamentally, keeping kids safe online is about communication, & thus the importance of starting the conversation to discuss online risks cannot be overstated ○ Basic ground rules like protecting passwords should become second nature • Safer Internet Day is observed on February 10th every year • The opportunities presented by the Internet outweigh the dangers, but all stakeholders including parents, educators, regulators & telecoms operators must commit to ensuring that our children are safe online

04-05-2015 Internet on brink of collapse: Experts • The internet is heading towards a 'capacity crunch' • The cables & fibre optics that relay information to our laptops, smartphones & tablets will have reached their limit within 8 years, & fibre optics can take no more data from a single optical fibre, scientists warned • The boom of internet television, streaming services & ever-more powerful computers has increased the strain on our communications infrastructure • The internet companies could always put down additional cables - but that will mean higher bills • In 2005, broadband internet had a maximum speed of 2 mb/sec. Today 100 mb/sec download speeds are available in many parts of the world

Net Neutrality Saturday, May 10, 2014 2:31 PM

• Net neutrality is the principle that internet service providers (ISPs) should not be allowed to discriminate btw packets of data or charge differently by user, content, site, platform, or application • Net neutrality means all end users are able to access content, applications & services of their choice at the same level of service quality, internet speed & price with no priority or degradation based on the type of content, applications or services • Net neutrality ensures that the wealthiest website or one with virtually no resources has equal access to the users • Net neutrality advocates argue that the internet is akin to a public utility, as essential to the functioning of modern society like electricity • Today, there are about 1 billion websites, of which about 175 million are active • The bulk are small organisations, movements, non-commercial news organisations, or new service providers • These websites & innovative services springing up on the Internet every day would be badly hurt without net neutrality • The Internet would, then, be very much like cable TV, where select TV channels are carried by networks to viewers Net neutrality & start ups • The principle of net neutrality — that an ISP cannot discriminate btw packets of data — has been integral to the evolution of the internet into the innovative, disruptive marketplace of ideas ○ The economics of internet entrepreneurship would be affected by compromising on net neutrality ○ Currently, costs are low enough to allow startups to offer their apps & services to consumers without initial outside funding

Internet as a right

14-01-2016 Dr.Tilak HR New era of Internet rights activism • A strong opinion has emerged that those who cannot afford connectivity must be provided some basic free connectivity as an entitlement to be ensured by the govt • Such emerging public opinion in favour of free basic connectivity, if concretised into public policy, will be the first true expression of the Internet as a right, a concept which has begun to be discussed globally • There is emerging public consciousness which now sees the Internet not just in pure market terms, but as a unique social phenomenon which requires special public interest regulation • It is likely to usher a new era of Internet rights activism, with people claiming digital technologies as a right & not just something that the market provides on its own terms especially in the emerging world of Internet of Things • The Internet can be seen as a new neutral system of society, one that organises our lives, which can become very dangerous if its manipulative potential is not closely watched & kept in check Platform neutrality • There will always be corporatist tendencies to place ‘control points’ on this neutral network, with various kinds of free services as the incentive, but which would lead to far greater economic & other forms of exploitation ○ An eg. is just how Facebook used its monopoly social networking platform for a huge political campaign in its own favour pushing hard for its 'Free Basics', making & sharing lakhs of template responses to the TRAI’s consultation . The same platform functionality was not available to other users, who could be holding other views on the subject . The implications of such ‘platform abuse’ are grave • A monopoly social networking platform should be allowed to discriminate among its users in such a blatant way & with such far-reaching social consequences • Net neutrality & ‘zero-rating’ are therefore just the first key Internet regulation issues that we are facing • As the Internet quickly transforms our social systems & becomes an essential element, there will soon be other kinds of ‘platform neutrality’ issues • The EU is already conducting a public consultation on ‘platform governance’. The French Digital Council has brought out a comprehensive report on platform neutrality. A draft bill on Internet rights in the Italian legislature lays out public interest guidelines for platforms

US internet regulator & net neutrality

04-04-2014 Brazil’s internet law- internet bill of rights • It enshrines the principle of net neutrality • It also ensures that 100m Brazilian internet users enjoy online privacy (by barring providers from scanning through their data) & freedom of expression (a court order is required to force the removal of contentious content) • It also extends the reach of Brazilian law to any internet service in the world with Brazilian users ○ Penalties include fines of up to 10% of a firm’s Brazilian revenues or even blocking services

10-05-2014 Pressure mounts on FCC over net-neutrality changes • > 50 venture capitalists & 100 technology companies & > 100 civil liberty groups have sent a letter expressing concerns about proposals to allow internet service providers (ISPs) to charge for prioritised network access • The debate has taken on new urgency in recent months as ISPs grow increasingly impatient with the glut of bandwidth-heavy services such as video-on-demand ○ They want to charge companies such as Netflix, Amazon & Disney a fee to ensure their traffic is carried at high speed on their networks ○ In Feb 2015, Verizon won a landmark case that challenged the FCC's right to stop it charging such fees

12-05-2014 • US internet regulator is increasingly isolated on the controversial plan to junk net neutrality • In April 2014, the US Federal Communications Commission announced a plan to propose new rules that would allow internet giants like Google, Amazon & Netflix to pay internet service providers (ISPs) for privileged “last mile” delivery of their data packets to consumers, effectively creating a tiered internet with “fast lanes”, where deep- pocketed companies would be able to protect their dominant positions from challenges by start-ups ○ If established companies are able to pay for better access speeds or lower latency, the internet will no longer be a level playing field • Brazil recently passed an exemplary internet governance regulation that enshrined net neutrality in law

12-11-2014 • US President Obama’s unequivocally supported an open, undifferentiated internet • This means that ISPs cannot restrict speed or access for companies depending on how much bandwidth they consume • Creating “fast lanes” for certain content, or for only some deep-pocketed privileged websites, would harm the level playing field that has been integral to the emergence of once-upstarts like Google and Facebook • In the US, ISPs have campaigned against net neutrality • In early 2014, the FCC controversially seemed to undermine net neutrality, attracting fierce criticism and prompting a rethink • FCC is due to unveil new rules on net neutrality soon • As the debate continues in the US, India too should enshrine net neutrality in law

25-11-2014 • Proponents & opponents of net neutrality highlight two equally important aspects of the future role of internet in our lives — the right to its content & the incentive to create the infrastructure to access it ○ Thus, AT&T & Comcast in the US want large content players, such as Netflix & Google, whose video services consume almost half their bandwidth, to share the costs of creating & maintaining infrastructure ○ Accepting such a demand is a downhill slope for content companies, whose advertisement-driven business models depend on increasing reach & usage of date services

27-02-2015 US regulator approves 'net neutrality' rules for ISPs • ISPs now must act in the "public interest when providing a mobile connection to your home or phone, under rules approved by US FCC

Computer n Communication Technology Page 15 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

approved by US FCC • The plan puts the Internet in the same regulatory camp as the telephone & bans business practices that are "unjust or unreasonable" • The goal is to prevent providers from slowing or blocking web traffic, or creating paid fast lanes on the Internet

15-04-2015 Situation abroad • The US Federal Communication Commission in February 2015 made net neutrality binding on service providers in the US, treating them as 'common carrier' services • Chile was the earliest adopter of net neutrality with Netherlands & Brazil following suit. The EU is expected to join the list soon

Net neutrality in India

25-11-2014 • In India, the challenge is scarcity, not competition (as in US), as the broadband market suffers from small size, not from dominance by any player or technology • Fixed lines constitute barely 1/3rd of India’s limited broadband connections ○ Roughly 90% of the 251 million users of the internet access it on mobile phones ○ Wireless networks pose unique challenges for ensuring net neutrality ○ Expanding or upgrading the predominantly narrowband wireless network is a financial, technical & regulatory challenge ○ Imposing net neutrality prematurely might be counterproductive in India ○ India needs massive investments in its networks — wireless & wireline infrastructure — to reach the levels of developed countries ○ Net neutrality could hurt unserved regions, where the profits from it will already be weak • Major promoters of net neutrality, such as Facebook & Google, recognise the environment in developing countries ○ They are entering “zero rating” arrangements with mobile operators to offer preferential, cheap or free access to their services

11-02-2015 Facebook launches Internet.org in India • Facebook announced a tie-up with Reliance Communications to launch Internet.org in India ○ The tie-up gives subscribers of the Reliance Communications who have Internet-enabled handsets free access to 38 Websites – a mix of news, music, education, weather & health sites ○ The list includes Facebook, Wikipedia, & Reliance Astrology etc. ○ The lone search option available is Microsoft’s Bing. They can be accessed via an Android app +ves • This partnership will not only accelerate internet penetration In India, it will also open new socioeconomic opportunities to users in fields like education, information & commerce • This can be a big step forward in the efforts to connect every one in India to the internet & help people discover new tools & information that can create more jobs & opportunities -ves • They're offering a limited version of the internet, one that centers on Facebook, to low-income internet users ○ This raises concerns that this is not a charitable effort, but a customer acquisition strategy ○ The Internet.org model violates most definitions of net neutrality, as it provides access to a limited menu of services claiming to be the Internet rather than providing actual access to the Internet at a low cost • Since it is an exclusive deal with a single mobile service provider, it also calls into question the genuineness of Facebook’s publicly-stated motive of bringing the Internet to a billion people

28-03-2015 TRAI seeks views on net-neutrality • There are no norms for net neutrality in India as of now • Worldwide, there is an ongoing debate among govts, industry & consumers regarding regulations of OTT (over-the- top services like Whatsapp, , Hangouts etc.) services & net-neutrality

Computer n Communication Technology Page 16 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

top services like Whatsapp, Skype, Hangouts etc.) services & net-neutrality • Presently, users are not charged any fee by the operators to make calls or send messages using these applications. They just need to pay the regular data charge for Internet browsing ○ However, telecom operators are of view that the OTT are eating up a part of their revenues without investing in networks ○ Recently, received a lot of flak when it had announced plans to charge extra for Internet voice calls. It later rolled back the plans ○ The issue, however, led to intense debate over the issue of net-neutrality in India • The impact on voice services in India due to OTT is not considerable ○ As voice calling rates here are the lowest ○ Also, mobile internet penetration is only around 20%, that too predominantly on 2G, & quality of service of such OTT apps is not as good as traditional voice services offered by operators ○ However, there is some amount of cannibalisation on international calling, where rates are substantially higher

04-04-2015 • After spending billions of dollars in setting up infrastructure & bringing themselves under regulatory scrutiny, telecom companies can’t bear the fact that numerous applications ride on their networks for free ○ Some of the apps have millions of subscribers & command valuations of billions of dollars ○ Some like Skype & WhatsApp compete head on with the voice & messaging offerings of the telcos, who to be fair also need money to invest in building networks ○ Still, what’s not to be forgotten is that the telcos do benefit from the apps that piggyback on them ○ More app usage means more data consumed & more money inflow. Whether telcos are really aggrieved or not is debatable • The licence to violate net neutrality will mean telcos could now be in a position to ensure some sites are served faster than others ○ It could also mean it becomes costlier to use certain applications ○ Most importantly, it could endanger the very feature of the Internet that has over the years made it possible for countless start-ups, right from the to the Flipkarts, to dream & act big ○ It’s well acknowledged that the Internet has disrupted the world of business like no other technology has in recent decades . It has helped start-ups with hardly any capital & clout to still make a mark . So by rejecting net neutrality, which will enable telcos to play the gatekeeper to a valuable resource, we will be shutting the door on the entrepreneurial aspirations of millions • The absence of net neutrality will definitely benefit the telcos while at the same time harming the market by unleashing monopolistic tendencies ○ Telcos don’t want to be dumb pipes that agnostically transfer data. The cost of their ambition will be the loss of the Internet’s openness

09-04-2015 • After Reliance Communications decided to provide free access to partner applications & websites, Bharti Airtel has announced the launch of , where it will give free access to partner apps ○ This has fired up the simmering debate around net neutrality • Net Neutrality is a concept where content & application providers get equal treatment by ISPs. There is access to all websites, nothing is blocked, & the speed of access is not differentiated • By entering into a partnership, the telecom operators provide preferential access to the website or application of the provider &, in turn, generate revenue from them ○ For the website owner or application provider, this gives them access to millions of customers of the telecom operator, thereby leading to a pick-up in their number of transactions, & ultimately lifting their valuation

10-04-2015 • The debate on net neutrality picked up steam in 2010, when the US Federal Communications Commission (FCC) lost its case against Comcast in the US Supreme Court (FCC lost arguing against net neutrality) • TRAI recently sought public comments on net neutrality • the govt will have to step in & treat internet access as a utility & make investments in infrastructure • Breach of net neutrality will lead to a collapse of the start-up market & negatively impact innovation • Another aspect of paid prioritisation is free data. The consumer can be disincentivised to use rival apps. The

• Another aspect of paid prioritisation is free data. The consumer can be disincentivised to use rival apps. The problem arises when a clearly inferior product is given preference. This goes against internet, where meritocracy rules • Facebook & Google’s recent decision to join the COAI (Cellular Operators Association of India) is worrying ○ The COAI counts among its members carriers like Airtel & Vodafone, lobbying the govt & Trai to do away with net neutrality ○ This contradicts their stance in the US, where they joined a coalition of companies to advocate for net neutrality

14-04-2015 • the Competition Commission of India is examining whether Indian telecom operators are violating net neutrality • Unfortunately, the TRAI's Consultation Paper on Regulatory Framework for Over-the-Top (OTT) Services appears to propose only 2 choices: that we either accept licensing of Internet services or compromise on net neutrality ○ If TRAI’s claims are accepted, any business that uses the Internet — e-retail, media or health care — can potentially be regulated by TRAI as an OTT service. This is indeed regulatory overreach on a grand scale ○ The definition of the Internet as a bunch of OTT services that may need licensing has the potential of creating a closed Internet ○ The Internet has grown due to its open character. Anybody can connect to the Internet & offer an application or a service, or provide a website containing blogs & other content • If net neutrality is violated, telecom operators would not have incentive to expand their infrastructure or bandwidth ○ Once bandwidth is choked, bigger Internet players will be willing to pay network operators to speed up their packets ○ Net neutrality regulation, thus, provides an incentive to expand the network to relieve congestion, rather than constrain the bandwidth for earning monopoly profits ○ This was recognised most recently in the American Federal Communication Commission’s decision to classify Internet services as a public utility, thus adopting net neutrality • TRAI can regulate monopolies directly, or refer such issues to the Competition Commission ○ It can also regulate the interconnection rates btw external networks that connect to Indian networks ○ All Internet companies such as Google & Facebook use their home networks to connect to Indian consumers, with servers located in their home jurisdiction ○ Higher delivery charges would help create extra revenue for the Indian network operator

14-04-2015 • Internet is one of the finest creations of the human mind & it is a property of the entire human race • Brazil, an emerging market peer where internet penetration is around 50% passed an “internet bill of rights” that makes in 2014

15-04-2015 Legal provisions • The IT Act 2000 does not have provisions that prevent service providers from controlling the internet to serve their business needs. Trai's guidelines promote non-discrimination but the body is advisory in nature • Net neutrality as a concept is not defined under Indian law, but it is directly connected with Article 21, which pertains to the Right to Life. One cannot lead a dignified life without access to the Internet

• Anything curtailing net neutrality would also derail Digitial India Situation abroad • The Federal Communications Commission just recently voted for what is seen as strong Net neutrality rules. This is to ensure ISPs neither block, throttle traffic nor give access priority for money • Europe is trying to correct a 2013 proposal for Net neutrality, in which privileged access was allowed to 'specialised services.' This was vague & threatened Net neutrality • Chile last year banned zero rated schemes, those where access to social media is given free to telecom subscribers

15-04-2015 Situation abroad • The US Federal Communication Commission in February 2015 made net neutrality binding on service providers in the US, treating them as 'common carrier' services • Chile was the earliest adopter of net neutrality with Netherlands & Brazil following suit. The EU is expected to join

• Chile was the earliest adopter of net neutrality with Netherlands & Brazil following suit. The EU is expected to join the list soon

20-04-2015 • The Internet Age has thrown a new class system comprising Netizens & Citizens. Thanks to the social media, the Netizens have become a powerful force. And, their collective bargaining capacity is proving to be an effective trend- setting tool

23-04-2015 Net neutrality violation takes away right to free speech • Freedom of speech also means the freedom to listen. When several people speak (in the sense that there are several apps & websites available) but I can listen to only a few (as in, some apps & websites may be slower or could cost more), it violates the freedom of expression • When some websites & applications come free of usage costs, it would influence user away from content that has to be paid for, establishing discrimination based on price. Similarly, regulators should ensure that telecom service providers do not practice non-price discrimination whereby they can throttle the speed of access to certain web- sites while allowing faster access to preferred sites

28-04-2015 Govt looks at law to clarify ‘dos & don’ts’ • Against the backdrop of telecom players repeatedly challenging regulatory rulings in the US, the govt & the TRAI are veering towards the view that there is a need for a public law spelling out “dos & don’ts” to ensure net neutrality ○ DoT has constituted a committee to look into it ○ Clearly defined “do’s & don’ts” will see India stand out among nations on the extent of neutrality & regulatory measures undertaken to enforce them ○ Very few countries have opted for specific legislations on net neutrality • At present, there are no legal provisions for either the govt or the regulator to enforce non-discriminatory access to the internet (net neutrality) • While TSPs Airtel & Reliance launched separate services in association with select content providers offering free data access to their websites, they soon withdrew it, not coz of any govt or regulatory fiat, but due to a public outcry • As things stand today, very high internet traffic growth rate is leading to network congestion & spectrum crunch, forcing TSPs to adopt traffic management tools that restrict flow of data on the Internet ○ They also employ a host of tariff & commercial measures that militate against principles of net neutrality, such as data caps & fair usage policy, thereby incentivising & discriminating with select content & apps

05-05-2015 • Facebook CEO Mark Zuckerberg said that it is not sustainable to offer the whole internet for free but is possible for internet.org to give basic services without any cost ○ Facebook also said that Internet.org is open to all content & application developers who meet certain guidelines ○ This follows criticism from free web advocates that the social networking site was "hand- picking services" violating principles of net neutrality

Telecom panel on net neutrality

15-05-2015 Telecom panel bats for net neutrality • The committee feels that law should be put in place to explicitly prohibit mobile operators from offering differential tariffs for internet-based voice calls & data surfing as well as sponsored data such as Airtel Zero or Facebook’s Internet.org ○ Such offerings, the committee feels, go against the tenets of net neutrality • The proposed law will clearly lay down when an operator can block sites or slow down speeds, which would be allowed only if it spots illegal content, spam, viruses & as part of traffic management during periods of congestion or emergency • Evolution of technology cannot be stopped. Technology can be disruptive & operators have to adapt their business models or perish

models or perish

DoT’s Net Neutrality report

• The report is recommendatory in nature which along with the report of TRAI — when it comes — would be used by the govt to finalise its policy on net neutrality

17-07-2015 What is the big takeaway from the DoT committee report on Net Neutrality? • The Dept of Telecommunications’ (DoT’s) Net Neutrality report says “the core principles of Net Neutrality must be adhered to”, & that user rights on the Internet need to be protected — so that service providers are not able to restrict their ability to access any service on the Internet What does it say on the continuing use of OTT messaging services such as WhatsApp & Skype? • It rejects the demand for regulation of over-the-top (OTT) messaging services. But the panel is okay with subjecting VoIP calls within the country to regulation — & calls for a liberal approach on OTT VoIP international call services • What is unclear is how the govt will make the distinction btw VoIP OTTs & Messaging OTTs, as these two spheres are the same now • The committee has said that while messaging on an OTT service like WhatsApp should not regulated, if the same app also offers voice-calling services, they should be subject to regulations that are already in place for TSPs/ISPs So does this mean TSPs/ISPs have no choice but to continue to allow these OTT messaging services? • Service providers cannot regulate messaging services as per the recommendations What about zero-rating platforms like Facebook’s Internet.org & Airtel Zero? • The committee says that “content & application providers cannot be permitted to act as gatekeepers” & go against the principles of Net Neutrality • It also notes that very often the content market sees the rise of a leader, & that if these end up directing users to “specific content”, it amounts to a violation of Net Neutrality • Based on what the committee has recommended, Internet.org or even Airtel Zero rating app will be seen as violating the principle of Net Neutrality What does the panel say on traffic management practices by TSPs or ISPs? • While the report is in favour of “legitimate traffic management practices”, it says that TSPs/ISPs must make adequate disclosures to users about their traffic management policies • Additionally, traffic management that is “exploitative or anti-competitive” should not be allowed • Essentially, if a TSP starts, say, a video-streaming or music service, it cannot slow down the speed of a competing service of a similar nature on its networks What about tariff plans? Can TSPs/ISPs offer lucrative tariff plans in return for claiming for themselves the right to gatekeep the content you access? • No. The panel says tariff plans offered by TSPs/ISPs must conform to the principles of Net Neutrality, & TRAI will have the power to examine these tariff plans • So a special tariff plan for WhatsApp or even Wikipedia which offers the service for free, could be seen to be in violation of the principle of Net Neutrality What does the committee say on ? • The committee has not made any recommendations on the issue, other than flagging this as a concern for public policy • Search neutrality demands that search engines not base their rankings on editorial decisions, & show results based on relevance What happens now? • These are recommendations of the panel, & finally TRAI will have to decide what to adopt. Even after that, the regulations could face legal challenges from stakeholders

17-07-2015 • Taking a somewhat middle-of-the-road approach, a DoT-appointed committee on net neutrality has recommended that apps of OTT players like Skype, WhatsApp & Viber can continue to be used for making international calls or for messaging, but they will have to be licensed when they are used for making either local or national long-distance (NLD) calls • While partial regulation of OTTs has been recommended by the DoT panel, on the contentious issue of sponsored

• While partial regulation of OTTs has been recommended by the DoT panel, on the contentious issue of sponsored data plans it broadly views them against the principles of net neutrality

20-07-2015 • DoTs’ recent report on net neutrality recommended to bring VoIP domestic calling services, including applications such as WhatsApp, under licensing ○ The suggestion is that such services be regulated “through exercise of licensing powers available under section 4 of the Indian Telegraph Act to ensure a level playing field” ○ This does not straightaway mean such calls will be chargeable ○ The more obvious implication is that such applications can’t operate without the govt’s permission, which might be granted only on the fulfilment of certain conditions or the payment of a fee, or both • The report repeatedly pitches for net neutrality

21-07-2015 • The DoT report refers the most contentious section on the Zero Rating services such as Airtel Zero & Facebook- Reliance Internet.org back to TRAI • DoT’s treatment of VoIP is also inconsistent: it proposes that domestic VoIP calls be licensed, but not international calls • The report accepts that net neutrality principles are basic to the Internet

29-09-2015 Digital divide & Internet for all Facebook's idea • Free Basics is more open than its earlier avatar (Internet.org) ○ Facebook opened up its platform for outside developers ○ Encryption of information flowing through the platform is the other initial loophole that has been plugged • There is also some merit in the thinking that people who can afford Internet cannot sit in judgement about the quality of Internet that is made available for those who cannot afford it • All of that, however, can’t erase the fundamental problem with such a service, which is that it allows Facebook to be a gatekeeper to the Internet where none existed earlier • Free Basics is a suboptimal solution to the problem of lack of Internet access Better alternative • There are alternatives that manage to offer free data to users without donning the role of a gatekeeper • One such alternative goes by the name Jana, the Boston-based start-up • Jana rewards its smart phone users in 2 ways- ○ It reimburses users the cost of downloading its clients’ app ○ It also gives them free data, with which they can access any content online

08-10-2015 Ethical concerns of Net neutrality • In the absence of a specific law mandating a neutral Internet, telecom companies can discriminate btw different applications ○ In April 2012, Airtel announced Airtel Zero, an initiative that would allow applications to purchase data from Airtel in exchange for the telecom company offering them to consumers free of cost • Telecom companies that wish to discriminate btw applications & Facebook argue that some access is better than no access at all • Basically it is a clash of values: btw access to the Internet (in a limited form) & the maintenance of neutrality ○ The fundamental core of Internet lies in a commitment to both openness & a level playing field ○ Problem with Free Basics & Airtel Zero, is that the consumer has no choice in which websites he or she might want to access free of cost (paternalistic web) ○ Although Facebook’s CEO argues that these two values are not fundamentally opposed to each other, but can coexist. He is possibly correct at a theoretical level ○ But the history of markets tells warns us to be very careful in allowing predatory practices, devised to achieve short-term goals ○ As citizens, each of us has a fundamental right to freedom of speech & expression which might be affected if we allow the domination by a few applications

Computer n Communication Technology Page 21 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

allow the domination by a few applications ○ They are trying to achieve a laudable end, but by unethical means • Negating Net neutrality, in a bid to achieve greater access to the Internet could prove profoundly injurious in the long run ○ It could eventually lead to these telecom companies abusing their dominant positions ○ Consumers might benefit in the short run, only for serious damage to competition in the long run

30-12-2015 Dr.Tilak HR Free Basics from Facebook: violating net neutrality in disguise • Free Basics is not free, basic Internet as its name appears to imply. It has a version of Facebook, & only a few other websites & services that are willing to partner Facebook’s proprietary platform ○ TRAI has stopped this service for now, pending its public consultation on the subject • Today, there are nearly 1 bn websites. If we consider that there are 3.5 bn users of the Internet, 1 out of 3.5 such users also offers content or services • The reason that the Internet has become such a powerful force for change in such a short time is precisely coz anybody, anywhere, can connect to anybody else, not only to receive, but also to provide content. All that is required is that both sides have access to the Internet • All this would stop if the ISPs or telecom companies are given the right to act as gatekeepers • Tim Wu, the father of net neutrality, has written that keeping the two sides of the Internet free of gatekeepers is what has given a huge incentive for generating innovation & creating content • This is what has made the Internet, as a platform, so different from other mass communications platforms such as radio & television • In spite of this increase in connectivity, we have another 600 million mobile subscribers who need to be connected to the Internet • Instead of providing Facebook & its few partner websites & calling it “basic” Internet, we need to provide full Internet at prices that people can afford • The main barrier to Internet penetration is the high cost of data services in the country • Till now, TRAI has not regulated data tariffs. It is time it addresses the high price of data in the country • There are various ways of providing free Internet, or cost-effective Internet, to the low-end subscribers ○ They could be provided some free data with their data connection, or get some free time slots when the traffic on the network is low ○ 2G data prices should be brought down drastically, as the telcos have already made their investments & recovered costs from the subscribers • The danger of privileging a private platform such as Free Basics over a public Internet is that it introduces a new kind of digital divide among the people ○ A large fraction of those who will join such platforms may come to believe that Facebook is indeed the Internet

30-12-2015 Dr.Tilak HR Providing affordable internet: Ensuring greater competition & level playing field • Much like primary education, an Internet connection allows a citizen to participate in the modern economy. Just as society as a whole benefits if all citizens are educated, it benefits if all citizens are connected • If the objective is to connect the whole world to the Internet, then Free Basics by Facebook (previously known as internet.org) is a controversial method to achieve it ○ The company wants to provide a subset of the Internet free of charge to consumers, with mobile telecom operators bearing the costs of the traffic. Facebook acts as the unpaid gatekeeper of the platform ○ This kind of arrangement has come to be called “zero rating” & attracted criticism from Internet civil society groups ○ Free Basics scheme has “one unavoidable, inherent flaw: Facebook’s central role, which puts it in a privileged position to monitor its users’ traffic, & allows it to act as gatekeeper ○ There is no technical restriction that prevents the company from monitoring & recording the traffic of Free Basics users • Zero rating in general & Free Basics by Facebook in particular has many defenders among advocates of free markets & capitalism. They argue that if the mobile operator wishes to lose money or cross-subsidise some users at the cost of others, then it should be allowed to do so • Competition is the key But, how did the hundreds of millions of people around the world become Internet subscribers?

○ But, how did the hundreds of millions of people around the world become Internet subscribers? ○ coz they could afford it. They could afford it coz market forces — competition — drove prices down to levels that made an Internet connection affordable ○ Unless govt policies get in the way, there is no reason why the same forces will not reduce prices further to make the service affordable to ever more people, with lower disposable incomes ○ There is empirical evidence for this: . The 980 million mobile phone subscribers in India are able to make phone calls coz they can afford the charges. All this happened without a mobile phone operator providing free calls to a limited set of numbers . They also cut costs by skimping on customer service, overloading spectrum & sharing tower infrastructure . Operators innovated in retailing, launching prepaid packages & recharging these connections ○ TRAI should reflect on its own success in transforming India from a low teledensity country to a moderately high teledensity one & ensure market competition is allowed to take its course ○ TRAI can give license to more telecom operators ○ The govt can make enough spectrum available so that mobile operators can lower prices & ensure adequate service quality • The path to achieving the dream of Digital India lies not in foreign companies deciding on what basic services India’s poor ought to access free of charge, but by encouraging ever greater competition & a level playing field • The regulator should have a hawkish approach towards anti-competitive behaviour by existing market players • Growth as a force multiplier ○ If the Indian economy grows at 8% over several years, the income effect will make Internet connections more affordable even if prices do not fall ○ In other words, the best scheme to bring the Internet to all involves boosting competition to bring down prices & pursuing economic growth to raise people’s incomes

30-12-2015 GS II, III - by Dr.Tilak HR

• Net neutrality requires Internet be maintained as an open platform on which network providers treat all content, applications & services equally • Free Basics allows customers to access selected social networks, & services like healthcare, education & job listings from their phones without a data plan ○ In Free Basics, Facebook has decided voice over Internet protocol (VoIP) & video are not good for users, so they will not have them ○ Since Google hasn’t signed up as a partner with Facebook, users cannot access it. This also includes any of the billions of websites that haven't partnered with Facebook • India has just woken up to the advantages of mobile Internet & any such splitting will create a ‘have versus have not’s list' in the country ○ At the start of startup India revolution, we cannot have some Indian developers & entrepreneurs blocked by large corporates to access consumer Any segregation of the Internet into fast & slow, free or paid, app or web will undermine PM Modi's digital India

○ Any segregation of the Internet into fast & slow, free or paid, app or web will undermine PM Modi's digital India program • The practice of zero rating (toll-free data or sponsored data) is not compatible with this (net neutrality), since it allows companies to act as 'stronger gatekeepers' & discriminate against the open Internet • Free Basics developers can’t innovate on technology without the permission of Facebook • Telecom operators & Facebook also need to approve services • Free Basics shifts ‘agency’ (who has decision making rights) from the end user to Facebook. But India’s constitution guarantees ‘agency’ to each citizen, which is why they have fundamental rights & universal franchise • While Facebook may claim to be benign, once it is legally approved, others will abuse it for private gain, according to the experts • 'Digital Colonialism or Data colonialism', the exploitation of resources while denying rights ○ Free Basics, like all forms of zero rating, comes from the same school of thought that considers a 'benevolent dictatorship' better than democracy for progress • Companies should pay money, data time or anything else to the consumer directly by using tools like Gigato, a data- sponsoring app. These tools reimburse users for data without violating the net neutrality

06-01-2016 • Net neutrality has implications for issues concerning the development of the internet & its adoption in India ○ These include licensing of internet applications like those permitting voice calling, payment of carriage fees to telecom companies, & zero-rated plans like Internet.org/ Free Basics

Internet of things (IoT) 30 April 2014 08:03 The Internet of Things: Dr. John Barrett at TED: link- watch?v=QaTIt1C5R-M,

• IoT refers to a digital ecosystem where the needs of consumers are seamlessly recognised by Internet-connected devices around them, enabling the fast & automated delivery of services

30-04-2014 The Internet of things refers to uniquely identifiable objects and their virtual representations in an Internet-like structure. Kevin Ashton proposed the term Internet of things in 1999, though people have discussed the concept since at least 1991. If all objects and people in daily life were equipped with identifiers, they could be managed and inventoried by computers. Equipping all objects in the world with minuscule identifying devices or machine-readable identifiers could transform daily life. For instance, business may no longer run out of stock or generate waste products, as involved parties would know which products are required and consumed. A person's ability to interact with objects could be altered remotely based on immediate or present needs, in accordance with existing end-user agreements. For example, such technology could enable much more powerful control of content creators and owners over their creations by better applying copyright restrictions and digital restrictions management, so a customer buying a Blu-ray disc containing a movie could choose to pay a high price and be able to watch the movie for a whole year, pay a moderate price and have the right to watch the movie for a week, or pay a low fee everytime she or he watches the movie. Today however, the term Internet of things (commonly abbreviated as IoT) denotes advanced connectivity of devices, systems, and services that goes beyond the traditional M2M and covers a variety of protocols, domains and applications. According to Gartner, there will be nearly 26 billion devices on the Internet of Things by 2020. According to ABI Research, more than 30 billion devices will be wirelessly connected to the Internet of Things (Internet of Everything) by 2020. An alternative view, from the world of the Semantic Web focuses instead on making all things (not just those electronic, smart, or RFID-enabled) addressable by the existing naming protocols, such as URI. The objects themselves do not converse, but they may now be referred to by other agents, such as powerful centralized servers acting for their human owners. The next generation of Internet applications using Internet Protocol Version 6 (IPv6) would be able to communicate with devices attached to virtually all human-made objects because of the extremely large address space of the IPv6 protocol. This system would therefore be able to scale to the large numbers of objects envisaged.

Trends and characteristics Intelligence In the future the Internet of Things may be a non-deterministic and open network in which auto-organized or intelligent entities (Web services, SOA components), virtual objects (avatars) will be interoperable and able to act independently (pursuing their own objectives or shared ones) depending on the context, circumstances or environments. Architecture The system will likely be an example of event-driven architecture, bottom-up made (based on the context of processes and operations, in real-time) and will consider any subsidiary level. Therefore, model driven and functional approaches will coexist with new ones able to treat exceptions and unusual evolution of processes (Multi-agent systems, B-ADSc, etc.). Complex system In semi-open or closed loops (i.e. value chains, whenever a global finality can be settled) it will therefore be considered and studied as a Complex system due to the huge number of different links and interactions between autonomous actors, and its capacity to integrate new actors. At the overall stage (full open loop) it will likely be seen as a chaotic environment (since systems have always finality). Size considerations The Internet of objects would encode 50 to 100 trillion objects, and be able to follow the movement of those objects. Human beings in surveyed urban environments are each surrounded by 1000 to 5000 trackable objects. Time considerations

Computer n Communication Technology Page 25 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Time considerations In this Internet of Things, made of billions of parallel and simultaneous events, time will no more be used as a common and linear dimension but will depend on each entity (object, process, information system, etc.). This Internet of Things will be accordingly based on massive parallel IT systems (Parallel computing). Space considerations In an Internet of Things, the precise geographic location of a thing—and also the precise geographic dimensions of a thing—will be critical. Currently, the Internet has been primarily used to manage information processed by people. Therefore, facts about a thing, such as its location in time and space, have been less critical to track because the person processing the information can decide whether or not that information was important to the action being taken, and if so, add the missing information (or decide to not take the action). (Note that some things in the Internet of Things will be sensors, and sensor location is usually important.) The GeoWeb and Digital Earth are promising applications that become possible when things can become organized and connected by location.

Applications For example, Songdo, South Korea, the first of its kind fully equipped and wired ubiquitous, or smart city is near completion. Nearly everything in this digital metropolis of smart homes is planned to be wired, connected and turned into a constant stream of data that would be monitored and analyzed by an array of computers with little, or no human intervention. Thus, Internet of Things, or embedded intelligence in things, with "smart systems that are able to take over complex human perceptive and cognitive functions and frequently act unnoticeably in the background" is a close reality. Fields of applications include: waste management, urban planning, environmental sensing, social interaction gadgets, sustainable urban environment, continuous care, emergency response, intelligent shopping, smart product management, smart meters, home automation and smart events.

Criticism and controversies While technologists tout the Internet of Things as one more step toward a better world, scholars and social observers have some reservations and doubts about approaching ubiquitous computing revolution. Experts feel that technology already influences our moral decision making, which in turns affects human agency, privacy and autonomy. They caution against viewing technology merely as a human tool and advocates instead to consider it as an active agent. A different criticism is that the Internet of Things is being developed rapidly without appropriate consideration of the profound security challenges involved and the regulatory changes that might be necessary. In particular, as the Internet of Things spreads widely, cyber attacks are likely to become an increasingly physical (rather than simply virtual) threat. The American Civil Liberties Union (ACLU) expressed concern regarding what is, in their view, the ability of Internet- connected devices to erode people's control over their own lives. The ACLU wrote that "There’s simply no way to forecast how these immense powers -- disproportionately accumulating in the hands of corporations seeking financial advantage and governments craving ever more control- will be used. Chances are Big Data and the Internet of Things will make it harder for us to control our own lives, as we grow increasingly transparent to powerful corporations and government institutions that are becoming more opaque to us." One often-neglected concern regarding Internet-connected devices technologies pertains to the environmental impacts of the manufacture, use, and eventual disposal of all these semiconductor-rich devices. Modern electronics are replete with a wide variety of heavy metals and rare-earth metals, as well as highly toxic synthetic chemicals. This makes them extremely difficult to properly recycle. While these devices can serve as energy-conservation equipment, everyday good habits can bring the same benefits. Practical, fundamental considerations such as these are often overlooked by marketers eager to induce consumers to purchase automation items that may never have been needed in the first place.

30-04-2014 With the advent of the Internet of things, potentially billions of devices will report data about themselves, making it possible to create new applications in areas as diverse as factory optimisation, car maintenance, or simply keeping track of your stuff online

11-01-2015 • Put simply, this is the interconnection of smart devices through unique identifiers without requiring a human -to- human or human-to-machine interaction • Every device inside & outside our home will be seamlessly connected to each other

Computer n Communication Technology Page 26 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• Every device inside & outside our home will be seamlessly connected to each other • This, in turn, can lead to better healthcare, environmental monitoring, cyber security, even large-scale deployment as in the case of Songdo, South Korea’s prototype smart city that is nearing completion • Almost everything is to be connected & converted to a constant data stream to be monitored & studied without human involvement

India's IoT policy

28-01-2015 • WG-ICT deliberations with US on India’s IoT programme • building “smart cities” is contingent on an effective IoT policy • Such a system, however, relies on extensive data collected from citizens — vehicle records, dietary habits, or even consumption patterns — placing a premium on privacy & information security • Moreover, an IoT system needs sustained collaboration btw the domestic private & public sectors • In Oct 2014, the Dept of Electronics & IT put out a draft IoT policy • Foreign corporations will be keen to contribute to the “smart cities” project • the Indian IoT industry is estimated to be worth $15 billion by 2020 • before the WG-ICT can negotiate the terms of operation for US technology giants in India’s IoT market, domestic measures that account for data privacy & IPRs of local & foreign manufacturers must be in place

Mobile Phones 16 April 2014 09:31

• IMEI nos: The International Mobile Station Equipment Identity numbers are used to either locate or block the use of stolen mobile phones

Smart phones 09-06-2014 • The rise of cheap smartphones will allow vast portions of the population (from middle classes in cities to small businesses in rural areas) access to mobile broadband • Mobile commerce can offer endless opportunities for entrepreneurs • Mobile banking has given consumers cheaper access to their finances, reducing the need to travel to bank branches • Health related apps provide basic information about health & medicine, reducing travel & the pressure on doctors

05-10-2014 Hit in India • Smartphone penetration in India is still low, at 10% in 2013-14 • Ever since the launch of the world’s first smartphones, the iPhone in 2008, they have been steadily proliferating • Smartphones now account for over 70% of total cell phones in developed markets • As people begin to understand the Internet & the power of data, the smartphone increasingly becomes a mass product. For many people, phones are the first gateway to the Internet

24-07-2015 • Smartphone penetration is now 26%

Cell phone radiation

29-01-2014

• With more than 90 crore mobile phone users across the country, business is booming for cell service providers in India. Falling prices and wider mobile coverage have led to the cell phone becoming a ubiquitous part of modern life. • There are around five lakh cell phone towers in the country. When a cell phone makes a call, the signal goes to the nearest base station tower, from there it goes to the base station tower nearest to the phone to which the call has been made. • The electromagnetic waves emitted by the towers travel in a cascading umbrella formation, making the strongest impact a few hundred metres away from the tower. This means that the building on which the tower is erected is relatively safe. • the radiation levels set by the government are far from safe, even after being reduced from 4,500 milliWatt per square metre to 450 milliWatt per square metre in September 2012. To put it in perspective, Austria allows radiation up to one milliWatt per square metre. • Numerous studies have confirmed that there is a direct link between proximity to cell towers and acoustic neuroma (a cancer of the inner ear), astrocytomas (all cancers of the brain), etc. • Recent studies have shown associations with cancers of the lung, pancreas, ovaries, thyroid and many childhood cancers • In India, cell operators are allowed to transmit 20W of power per carrier from the individual cell tower antenna. One

Computer n Communication Technology Page 28 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• In India, cell operators are allowed to transmit 20W of power per carrier from the individual cell tower antenna. One operator may have four to six carrier frequencies and there may be two to four operators on the same rooftop or tower. So, the total transmitted power may be 100 to 400W, making the entire area nearby an open microwave oven. • According to an independent group of scientists, who brought out the Bio-Initiative Report 2007, safe radiation density is 1.0 milliWatt per square metre for outdoor, cumulative RF (radio frequency) exposure and 0.1 for indoor. • The safe limit should be less than 0.1 milliWatt per square metre for indoor, cumulative RF exposure.

New mobile radiation norms from September 1, 2013 • Companies manufacturing or importing mobile phones for sale in India will have to ensure that the handsets are compliant with new radiation norms that will be effective from September 1 • With the new SAR norm, India would become one of few countries that are following the most stringent norm of 1.6 watt per kg average over six minutes period on 1 gram of human tissue • All companies will have to display radiation emitted from mobile phones on the handset in terms of SAR (specific absorption rate) unit

05-02-2014 Compliance with the Prescribed Limits of EMF Radiation from Mobile Towers: • WHO has recommended that “National authorities should adopt international standards to protect their citizens against adverse levels of RF fields. They should restrict access to areas where exposure limits may be exceeded” • WHO has referred to the International Commission on Non-lionizing Radiation Protection (ICNIRP) which has prescribed the levels limiting Electro Magnetic Field (EMF) emission from Base Transceiver Stations (BTSs) as safe for general public • DoT adopted the EMF radiation limits prescribed by ICNIRP in 2008 which was further reduced to 1/10th of the safe limit prescribed by ICNIRP with effect from Sept 2012 Display of Specific Absorption Rate (SAR) values on mobile handsets have been issued which include: • Mobile handsets manufactured & sold in India or imported from other countries shall be checked for compliance of applicable SAR limits • SAR level for mobile handsets shall be limited to 1.6 Watt/Kg, averaged over a mass of 1 gram of human tissue • SAR value is to be displayed on the handset similar to display of International Mobile Equipment Identity (IMEI)

17-04-2014 An unscientific report on ‘mitigating’ EM radiation effects by CPWD The Central Public Works Department (CPWD) uploaded a draft document titled “Guidelines for mitigation of the effects of electromagnetic radiations in built places” • The electromagnetic fields of vast array of frequencies & magnitude in the vicinity of human habitat may result into irreversible bodily changes which may be damaging & sometimes fatal too • It lists loss of memory, fatigue, dizziness, ringing in the ears, long reaction time heart palpitation, and cancer etc as health risks from electromagnetic radiation • The document hardly has any scientific basis, uses scary language & is riddled with questionable claims Comments • WHO in 2011 has classified 'radiofrequency' electromagnetic radiation as a possible group 2b carcinogen. This 2b group contains possible carcinogens with weaker evidence ○ No adverse health effects have been established as being caused by mobile phone use, the WHO states

22-04-2014 No link between mobile phone radiation & cancer, says Padma awardee doctor

• India-born oncologist Dr Siddhartha Mukherjee urged WHO to remove cellphone radiation from the list of possible carcinogens on the ground that the “preponderance of evidence suggests there is no link” btw radiation from mobile phones & cancer he argued that the drastic increase in cellphone usage does not mirror incidence of brain cancer, neither is the

○ he argued that the drastic increase in cellphone usage does not mirror incidence of brain cancer, neither is the radiation emitted by cellphones of the nature that can directly damage DNA ○ But there is not enough data to make a similar claim about radiation emitted by cellphone towers since the dosage is higher in this case

21-06-2014 • Ionising radiation causes damage to molecules, they break the chemical bonds & can cause health hazards ○ But non-ionising radiations (from mobile tower antennae & phones) do not cause breakage of bonds or damage the molecules (DNA break) ○ Such radiation cause only local change in temperature depending on the extent of use ○ the waves used in mobile phone technology are probably at the lowest end of the electromagnetic spectrum • A number of researches & studies have been conducted around the globe to ascertain if there is any relationship btw the emissions from the mobile phone & cancer. However, there is not enough evidence proving mobile phones cause cancer in humans

25-06-2014 Mobile radiation not harmful: Doctors, health experts • the entire issue began when some people made some co-relation between an incidence of cancer and telecom towers without any basis • Various environmental groups, NGOs & activists in India have voiced their concerns over adverse health affects from Electromagnetic Field (EMF) emissions from antennas on cell towers & mobile phones • This has led to opposition against setting up of mobile phone towers on buildings by various resident welfare associations in cities • All scientific research has found no health effect • Non-ionising radiation such as mobile emission causes only local change in temperature depending on the extent of use

29-01-2014 The ability to respond quickly to an email or text showcases your availability & allows you to meet tight deadlines. However, being in touch day & night sets us up for missteps brought on by distraction, heightened emotions & fatigue

16-04-2014 How mobile phones are making the world better • The cellphone has become more of a tool & less of a toy, especially among the poor, and those trying to help them, in emerging markets • It helps deliver, via text message, water, energy, financial services, health care & even education • WHO estimates that > 700 million people do not have access to clean drinking water & > 2.5 billion have no access to toilets. Yet according to the International Telecommunications Union, 96% of the world is connected via cellphone - which is why it has become a means of doing good • InSight: using mobiles to create credit scores for the poor and create a tool for customers in southern India without bank accounts or financial histories.

Quantum Computing 27 February 2014 23:35

Quantum Computers Animated, +Nanotechnology Documentary Quantum Computing, what it is, how it works, D-Wave Quantum Computer

A quantum computer (also known as a quantum supercomputer) is a computation device that makes direct use of quantum-mechanical phenomena, such as superposition & entanglement, to perform operations on data Introduction • Moore's Law states, the number of transistors on a microprocessor continues to double every 18 months ○ The year 2020 or 2030 may find the circuits on a microprocessor measured on an atomic scale And the logical next step will be to create quantum computers, which will harness the power of atoms and molecules to perform memory and processing tasks. Quantum computers have the potential to perform certain calculations significantly faster than any silicon-based computer. Scientists have already built basic quantum computers that can perform certain calculations; but a practical quantum computer is still years away. Quantum computing was first theorized less than 30 years ago, by a physicist at the Argonne National Laboratory. Paul Benioff is credited with first applying quantum theory to computers in 1981. Benioff theorized about creating a quantum Turing machine. Most digital computers are based on the Turing Theory Defining the Quantum Computer The Turing machine, developed by Alan Turing in the 1930s, is a theoretical device that consists of tape of unlimited length that is divided into little squares. Each square can either hold a symbol (1 or 0) or be left blank. A read-write device reads these symbols and blanks, which gives the machine its instructions to perform a certain program. Does this sound familiar? Well, in a quantum Turing machine, the difference is that the tape exists in a quantum state, as does the read-write head. This means that the symbols on the tape can be either 0 or 1 or a superposition of 0 and 1; in other words the symbols are both 0 and 1 (and all points in between) at the same time. While a normal Turing machine can only perform one calculation at a time, a quantum Turing machine can perform many calculations at once. Today's computers, like a Turing machine, work by manipulating bits that exist in one of two states: a 0 or a 1. Quantum computers aren't limited to two states; they encode information as quantum bits, or qubits, which can exist in superposition. Qubits represent atoms, ions, photons or electrons and their respective control devices that are working together to act as computer memory and a processor. Because a quantum computer can contain these multiple states simultaneously, it has the potential to be millions of times more powerful than today's most powerful supercomputers. This superposition of qubits is what gives quantum computers their inherent parallelism. This parallelism allows a quantum computer to work on a million computations at once, while your desktop PC works on one. A classical computer has a memory made up of bits, where each bit represents either a one or a zero. A quantum computer maintains a sequence of qubits. A single qubit can represent a one, a zero, or any quantum superposition of these two qubit states; moreover, a pair of qubits can be in any quantum superposition of 4 states, and three qubits in any superposition of 8. In general, a quantum computer with n qubits can be in an arbitrary superposition of up to 2n different states simultaneously (this compares to a normal computer that can only be in one of these 2n states at any one time) Quantum computers also utilize another aspect of quantum mechanics known as entanglement. One problem with the idea of quantum computers is that if you try to look at the subatomic particles, you could bump them, and thereby change their value. If you look at a qubit in superposition to determine its value, the qubit will assume the value of either 0 or 1, but not both (effectively turning your spiffy quantum computer into a mundane digital computer). To make a practical quantum computer, scientists have to devise ways of making measurements indirectly to preserve the system's integrity. Entanglement provides a potential answer. In quantum physics, if you apply an outside force to two atoms, it can cause them to become entangled, and the second atom can take on the properties of the first atom. So if left alone, an atom will spin in all directions. The instant it is disturbed it chooses one spin, or one value; and at the same time, the second entangled atom will choose an opposite spin, or value. This allows scientists to know the value

Computer n Communication Technology Page 32 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

same time, the second entangled atom will choose an opposite spin, or value. This allows scientists to know the value of the qubits without actually looking at them Quantum decoherence One of the greatest challenges is controlling or removing quantum decoherence. This usually means isolating the system from its environment as interactions with the external world cause the system to decohere. Decoherence is irreversible, as it is non-unitary, and is usually something that should be highly controlled, if not avoided QUBIT CONTROL Computer scientists control the microscopic particles that act as qubits in quantum computers by using control devices- • Ion traps use optical or magnetic fields (or a combination of both) to trap ions • Optical traps use light waves to trap and control particles • Quantum dots are made of semiconductor material and are used to contain and manipulate electrons • Semiconductor impurities contain electrons by using "unwanted" atoms found in semiconductor material • Superconducting circuits allow electrons to flow with almost no resistance at very low temperatures Today's Quantum Computers Quantum computers could one day replace silicon chips, just like the transistor once replaced the vacuum tube. But for now, the technology required to develop such a quantum computer is beyond our reach. Most research in quantum computing is still very theoretical The most advanced quantum computers have not gone beyond manipulating more than 16 qubits, meaning that they are a far cry from practical application. However, the potential remains that quantum computers one day could perform, quickly and easily, calculations that are incredibly time-consuming on conventional computers. Several key advancements have been made in quantum computing in the last few years. Let's look at a few of the quantum computers that have been developed 2007 Canadian startup company D-Wave demonstrated a 16-qubit quantum computer. The computer solved a sudoku puzzle and other pattern matching problems. The company claims it will produce practical systems by 2008. Skeptics believe practical quantum computers are still decades away, that the system D-Wave has created isn't scaleable, and that many of the claims on D-Wave's Web site are simply impossible (or at least impossible to know for certain given our understanding of quantum mechanics)

If functional quantum computers can be built, they will be valuable in factoring large numbers, and therefore extremely useful for decoding and encoding secret information. If one were to be built today, no information on the Internet would be safe. Our current methods of encryption are simple compared to the complicated methods possible in quantum computers. Quantum computers could also be used to search large databases in a fraction of the time that it would take a conventional computer. Other applications could include using quantum computers to study quantum mechanics, or even to design other quantum computers But quantum computing is still in its early stages of development, and many computer scientists believe the technology needed to create a practical quantum computer is years away. Quantum computers must have at least several dozen qubits to be able to solve real-world problems, and thus serve as a viable computing method

Cryptocurrency 31 January 2014 13:37

Bitcoins

• It is an open source P2P money • Bitcoin is described as the first decentralized digital currency • Being an 'open source' product, bitcoin can be mined by anyone through a complex computer software through solutions shared on an entire network, although the process is complex and such 'mining' can be done only on very powerful computers •

Basic Understanding Bitcoin is an experimental, decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority - managing transactions and issuing money are carried out collectively by the network. The original Bitcoin software by Satoshi Nakamoto was released under the MIT license. Bitcoin is one of the first implementations of a concept called crypto-currency which was first described in 1998 by Wei Dai on the cypherpunks mailing list. Building upon the notion that money is any object, or any sort of record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic context, Bitcoin is designed around the idea of a new form of money that uses cryptography to control its creation and transactions, rather than relying on central authorities. It gained popularity after 2009, in the wake of the global financial crisis Bitcoin uses public-key cryptography, peer-to-peer networking, and proof-of-work to process and verify payments. Bitcoins are sent (or signed over) from one address to another with each user potentially having many, many addresses. Each payment transaction is broadcast to the network and included in the blockchain so that the included bitcoins cannot be spent twice After an hour or two, each transaction is locked in time by the massive amount of processing power that continues to extend the blockchain. Using these techniques, Bitcoin provides a fast and extremely reliable payment network that anyone can use Technical features These are the basic features of any Bitcoin-like network. • Bitcoins can be transferred between arbitrary nodes on the network. • Transactions are irreversible. • Double spending is prevented by using a block chain. • Transactions are broadcast within seconds and verified within 10 to 60 minutes. • Transaction processing and money issuance are carried out collectively through mining. • Transactions can be received at any time, regardless of whether your computer is turned on or off. Economic rules These rules are enforced collectively by the Bitcoin network. • Hard limit of about 21 million bitcoins. • Bitcoins are divisible to 8 decimal places, yielding a total of approximately 21×1014 currency units. • Transactions are cheap and mostly free Advantages of BitCoins The proponents of this type of digital currency describe its potential benefits as follows: • Bitcoins are sent easily through the Internet, without needing to trust any third party. • Transactions are irreversible by design. • Funds received are available for spending within minutes. It can’t be stolen. • Cost very little, especially compared to other payment networks. • The supply of bitcoins is regulated by software and the agreement of users of the system and cannot be manipulated by any government, bank, organization or individual. • The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) to miners who help

Computer n Communication Technology Page 34 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) to miners who help secure the network. • The Bitcoin network never sleeps, even on holidays! • Bitcoin transactions are secured by military grade cryptography. Nobody can charge you money or make a payment on your behalf Disadvantages of BitCoins • Bitcoins Are Not Widely Accepted: Bitcoins are still only accepted by a very small group of online merchants. This makes it unfeasible to completely rely on Bitcoins as a currency. There is also a possibility that governments might force merchants to not use Bitcoins to ensure that users’ transactions can be tracked. Apart from this, high degree of anonymity is concerning as this currency might be used for illegal transactions. • Bitcoin Valuation Fluctuates: The value of Bitcoins is constantly fluctuating according to demand. As reflected in recent crash of its exchange value. • No Buyer Protection: When goods are bought using Bitcoins and the seller doesn’t send the promised goods, no action can be taken to reverse the transaction. This problem can be solved using a third party escrow service like ClearCoin, but then, escrow services would assume the role of banks, which would cause Bitcoins to be similar to a more traditional currency. • Risk of Unknown Technical Flaws: The Bitcoin system could contain unexploited flaws. As this is a fairly new system, if Bitcoins were adopted widely, and a flaw was found, it could give tremendous wealth to the exploiter at the expense of destroying the Bitcoin economy. • Built in Deflation: Since the total number of bitcoins is capped at 21 million, it will cause deflation. Each bitcoin will be worth more and more as the total number of Bitcoins maxes out. This system is designed to reward early adopters which lean towards so-called Ponzi scheme. Since each bitcoin will be valued higher with each passing day, the question of when to spend becomes important. This might cause spending surges which will cause the Bitcoin economy to fluctuate very rapidly, and unpredictably. • No Valuation Guarantee: Since there is no central authority governing Bitcoins, no one can guarantee its minimum valuation. If a large group of merchants decide to dump bitcoins and leave the system, its valuation will decrease greatly which will immensely hurt users who have a large amount of wealth invested in Bitcoins. The decentralized nature of bitcoin is both a curse and blessing. Apart from the above mentioned limitations of the Bitcoins, international community, especially, Central Banks of various nations (European Central Bank report, October, 2012) are concerned regarding misuse of this digital currency for illegal operations. The mass production of illegal drugs is widely recognized as devastating plague to all peoples of all cultures. A study administered by the United Nations found that in 2005, the global drug market generated approximately $321.6 billion US dollars, representing almost 1% of worldwide commerce. Now, as it is evident that BitCoins easily lend itself to money laundering and the anonymous nature of transactions. Unsurprisingly, one the most significant bottlenecks in the drug trade are the laundering of money from first-world markets to their final destination, generally in clandestine territories far from the reach of the law. A simple internet connection and some capital investment could completely eliminate the most significant obstacles to the flow of currency. It is apparent that there are many issues regarding the illegal drug trade and the viability of BitCoins. However, as we all know, it is only one of the many dastardly industries that would broadly benefit from BitCoins. For example, those who run prostitution rings or are human traffickers would greatly benefit as it would eliminate all tangible evidence, as history has witnessed that many criminals were only convicted of money-based crimes such as tax evasion. Therefore this, pivotal tool of law enforcement cannot be compromised. Not to mention, money laundering is the important tool used for terrorist group fundings and BitCoins may become a handy tool in the hands of enemies of humanity. Due to these concerns already Europen Central Bank has derecognised the BitCoin Currency transactions Bitcoin bubble Isn't it fitting that the next financial bubble could be triggered by speculation in a completely dematerialised currency? A Bitcoin is about as substantial as a hole in the ether, but it punched through the $1,000 barrier last week on Mt Gox, the biggest Bitcoin exchange, making it the most expensive currency on earth. Paradoxically, the digital currency achieved this feat shortly after the marketplaces where it first found favour, the escrow bazaars for contraband goods and services hidden inside the Tor anonymous network, were laid waste by law enforcement agencies and hackers. The responses to the sudden rally of Bitcoin are equally paradoxical. Germany is ready to invest in it. Ben Bernanke cautiously expects it to make something of itself in the future.And China has banned its banks from touching it. The most creative uses that people have dreamed up for the first completely digital currency range in ethical value from almost illegal to utterly contemptible. And ironically, a Bitcoin billionaire could starve to death, because you can't buy

almost illegal to utterly contemptible. And ironically, a Bitcoin billionaire could starve to death, because you can't buy food with it. But as commerce migrates online and sunders ties with banknotes and the paper trail, digital currencies will become mainstream. Bitcoin is only the first mover in a sunrise sector built on new ways of calibrating scarcity and value, the basis of all currencies. But don't break out the bubbly just yet. First, the bubble needs to be popped

14-02-2014 Risks • Bitcoin exchange rates are becoming extremely volatile ○ Bitcoins have no backing of any govt which means in the event of a liquidity crisis, nobody is bound by law to help • Potential money laundering risks ○ The source of traditional hard currency converted into Bitcoin is unknown, no records are being kept. So, they can be used to finance terror • There is a real chance of criminals using it for drug dealings & other illegal activities • Risk of 'e-ponzi' or an electronic version of investor fraud, given the growing promotion of bitcoin as an investment product without any enabling regulations for them • Cyber security issues, given the huge scope of money laundering & other illegal activities ○ Lured by so-called appreciation in bitcoin value, people may invest in this & risk losing everything • Digital currency is a totally new concept in India & even the jurisdiction is not clear as yet on who should regulate them

Is bitcoin a currency? • Bitcoin is not actually a currency. It's a store of value, a distributed ledger. It's a great place to put assets, especially in places like Argentina with 40% inflation where the govt's currency does not hold value • It's also a good investment vehicle if you have an appetite for risk. But it won't be a currency until volatility slows down. Whenever the regulatory framework is clearer, & the volatility comes down, then we can consider it as a currency

• Germany officially recognises bitcoins as a private money

• Silk Road website raided coz it dealt transactions only in bitcoins in exchange of criminal activities- FBI called it the most sophisticated criminal market place on the internet- specially coz of bitcoins anonymity

• It is next to impossible to stop bitcoins- sheer engineering marvel

08-03-2014 If a market for bitcoins exists, it should be regulated rather than demonised • Bitcoin's runaway success shows that there is a demand for a completely dematerialised currency which is not based on physical value but only on the calculus of scarcity, & which can be transmitted across the internet, bypassing formal banking channels • A market for such currencies obviously exists, & nations should collaborate to regulate them rather than driving them offshore & underground • In the media, Bitcoin coverage has been driven by the fear of the unknown ○ Stories highlight the popularity of Bitcoin with internet escrow services which facilitate peer to peer trades in drugs & other contraband ○ Reports abound about excessive Bitcoin volatility, about China banning the currency to prevent offshoring, about the biggest Bitcoin agency being hacked & filing for bankruptcy Conclusion • Digital currencies will be as mainstream as plastic money in the very near future

12-03-2014 A ban on bitcoin is not the answer to the RBI’s regulatory concerns. • In 2013, bitcoin boomed from $13 to $1,250 per unit value • The RBI issued a notification in Dec, 2013, cautioning users about the underlying fluctuations in the price of bitcoin & also the maintenance of its value

Computer n Communication Technology Page 36 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

& also the maintenance of its value • Virtual currency is a currency that relies on cryptography, peer-to-peer networking & decentralisation • Bitcoin is turning out to be “the perfect digital currency” with features like frictionless, anonymous & cryptographically secure • Given that bitcoin is invisible to law enforcement agencies & taxation depts, its growing appeal is understandable Concerns • The volatility in bitcoin results in high risk for investors • Taxes are seen as the medium of providing growth to the economy & virtual currencies like bitcoin are a threat to the federal taxation system due to their intrinsic quality of not identifying the person transacting in the currency • Money laundering - It is said to pose a threat to the federal economic system due to its links to black money & support for anti-national activities ○ Hawala transactions may take new shape through virtual currencies like bitcoin • There could be security risk in transactions relating to trading in virtual currencies like bitcoin (similar to plastic money as well) What should RBI do? • The RBI must not throw the baby out with the bathwater • If it desires to counter the rise of these currencies, it must take some intelligent steps like lowering the transaction fee; accelerating the process of receiving payments through cards or the banking system, etc. • The RBI could also try to incorporate virtual currencies in their framework for typical transactions like forex, which may counter the typical problems of current account deficit Conclusion • People invest to earn & if they think bitcoin helps earnings, they will trade in it; if not, bitcoin will perish automatically

12-03-2014 What is a Bitcoin? • Unlike traditional currencies issued by central banks, Bitcoin has no central monetary authority • It is under-pinned by a peer-to-peer computer network made up of its users’ machines, on the lines of networks like BitTorrent (a file-sharing system) or Skype (the audio, video & chat service) How are they generated? • Bitcoins are mathematically-generated by computers in the network executing complex number-crunching tasks, a process termed as “mining”. The mathematics of the Bitcoin system aims at a scenario where it becomes progressively more difficult to “mine” Bitcoins over time • First appearing in 2009, there are > 12 million Bitcoins in circulation • The system is set up so that it becomes increasingly difficult to produce them, with a maximum limit of 21 million expected by around 2140 • Bitcoin keeps a public register of every unit in existence & the network means that there is no need for a central authority • The computing power required to carry out the mathematical tasks is so great that it is currently impossible for any single computer to create Bitcoins on its own, ensuring that the network remains in control • The entire network is used to monitor & verify both the creation of new Bitcoins through mining, & the transfer of Bitcoins between users. A log is collectively maintained of all transactions How can one acquire it? • There are 3 main routes. Purchasing them at a Bitcoin exchange or exchanging Bitcoins with other individuals are the traditional routes. The 3rd route is through mining What are the risks? • A Bitcoin is not backed by a financial authority or real asset, which is why transactions are not subject to the same regulations as other currencies • While every single transaction made using Bitcoin is posted publicly, the identity of the user remains anonymous — making it hard to track perpetrators in the case of theft • The most common vulnerability is “user error”. Similar to physical cash stored in a digital form, Bitcoin wallets can be accidentally deleted, lost or stolen Has the currency run into major controversy? • The biggest controversy by far has been the one involving Mt Gox, a Bitcoin exchange based in Tokyo that had emerged as its largest trading platform. It was launched in July 2010, & by 2013 was handling an estimated 70% of all Bitcoin transactions

Computer n Communication Technology Page 37 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

all Bitcoin transactions • In Feb 2014, it suspended trading, closed its website & exchange service, & filed for bankruptcy protection. It said that around 850,000 Bitcoins belonging to customers & the company were missing & likely stolen, an amount valued at > $450 million at the time • The number of viruses designed to steal Bitcoins from wallets (programmes that hold Bitcoins on user’s computers or smartphones have increased greatly in the past year) ○ There’s no sophistication involved in the storage of bitcoin in wallets What did the RBI warn? • The RBI, in Dec 2013, warned the public against the use of virtual currencies such as Bitcoin, pointing out that users themselves to potential financial, legal & security related risks

21-03-2014 Future of crypto-currencies • The technology behind Bitcoin could support a revolution in the way people own & pay for things • Bitcoins don’t move around when they are transferred. They are best understood as entries in a giant ledger (record book) - the “blockchain”, which contains the transaction history for every Bitcoin in circulation • It is kept up to date with the help of cryptography & copious computing power, provided by a global network of tens of thousands of computers • Again, openness helps the system remain secure: the blockchain is public so every participant can check whether a transfer comes from the rightful owner • This set-up is the first workable solution to one of the difficult problems of the digital world: how to transfer something of value from one person to another without middlemen having to provide security for transcations ○ And Bitcoin does the trick while being open (unlike conventional payment mechanisms, which aim for security by shielding themselves from outsiders) • Bitcoin’s technology (blockchain) could be used to transfer ownership both in other currencies & of any kind of financial asset ○ This, in turn, would allow the creation of decentralised exchanges which let asset holders trade directly. And money could be “programmed” to come with conditions: for eg. it might be released only if a 3rd person agrees ○ Some want ownership of devices—a car, say—to be represented by a Bitcoin, or a tiny fraction of it . The car would work only when turned on with a key that includes the Bitcoin token. This would make managing ownership of & access to physical assets much easier . The token could be sold or rented out temporarily, enabling flexible peer-to-peer car-rental schemes. Such “smart property” would turn the blockchain into a global registry of ownership in physical assets • A number of startups are working on bringing such applications to market ○ Coloured Coins & Mastercoin will soon release software that enables trade in other financial assets, including stocks & bonds ○ The most ambitious project is Ethereum: it will launch a new blockchain, similar but unrelated to Bitcoin, with a programming language to encode financial instruments & other contracts • Even the banks too have started exploring how they could use the technology in other ways ○ Global banks could, for instance, use Bitcoin-like systems to move money btw subsidiaries. They could even issue their own crypto-currencies Some risks • Some experts say that the bitcoin network may reach its maximum capacity of 300,000 transactions per day as new applications come online • Another worry is that as the bitcoin blockchain, which has already trebled in size to 15GB in Feb 2014, continues to grow, fewer of the network’s participants will store it Conclusion • Even if Bitcoin were to break down, another similar system would most likely take its place

04-11-2015 How the bitcoin's technology can transform our economy? • BITCOIN has a bad reputation ○ The decentralised digital cryptocurrency, powered by a vast computer network, is notorious for the wild fluctuations in its value, the zeal of its supporters & its degenerate uses, such as extortion, buying drugs & hiring hitmen in the online bazaars of the “dark net” Analysis

Computer n Communication Technology Page 38 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Analysis ○ The value of a bitcoin has been pretty stable, at around $250, for most of 2015 ○ Among regulators & financial institutions, scepticism has given way to enthusiasm ○ the EU recently recognised it as a currency The “blockchain” technology behind bitcoins • The blockchain lets people who have no particular confidence in each other collaborate without having to go through a neutral central authority. Simply put, it is a machine for creating trust • An example of peer-to-peer technology with dubious origin but later revolutionised file sharing ○ A helpful analogy is with Napster, the pioneering but illegal “peer-to-peer” file-sharing service that went on line in 1999, providing free access to millions of music tracks ○ Napster itself was swiftly shut down, but it inspired a host of other peer-to-peer services ○ Many of these were also used for pirating music & films ○ Yet despite its dubious origins, peer-to-peer technology found legitimate uses, powering internet startups such as Skype (for telephony) & Spotify (for music streaming) Benefits of blockchain technology • It is a shared, trusted, public ledger that everyone can inspect, but which no single user controls ○ The participants in a blockchain system collectively keep the ledger up to date: it can be amended only according to strict rules & by general agreement ○ Bitcoin’s blockchain ledger prevents double-spending & keeps track of transactions continuously. It is what makes possible a currency without a central bank • Blockchains are also the latest example of the unexpected fruits of cryptography ○ Mathematical scrambling is used to boil down an original piece of information into a code, known as a hash ○ Any attempt to tamper with any part of the blockchain is apparent immediately— coz the new hash will not match the old ones ○ In this way this technology can help keep information secret (vital for encrypting messages & online shopping & banking) • Blockchains meet the need for a trustworthy record, something vital for transactions of every sort ○ Dozens of startups now hope to capitalise on the blockchain technology Potential uses • to make cheap, tamper-proof public databases—land registries • Financial-services firms are contemplating using blockchains as a record of who owns what instead of having a series of internal ledgers ○ it could save banks up to $20 billion a year by 2022 ○ 25 banks have just joined a blockchain startup, called R3 CEV, to develop common standards, & NASDAQ is about to start using the technology to record trading in securities of private companies • Blockchains can also implement business rules, such as transactions that take place only if two or more parties endorse them, or if another transaction has been completed first Blockchains threatening centralised institutions • The spread of blockchains may be threat to centralised institutions & bureaucracies, such as banks, clearing houses & govt authorities that are deemed sufficiently trustworthy to handle transactions • Given the decline in trust in govts & banks in recent years, a way to create more scrutiny & transparency could be no bad thing Way ahead • Drawing up regulations for blockchains at this early stage would be a mistake: the history of peer-to-peer technology suggests that it is likely to be several years before the technology’s full potential becomes clear • In the meantime regulators should find ways to accommodate new approaches within existing frameworks, rather than risk stifling a fast-evolving idea with overly prescriptive rules • The blockchain has the potential to transform how people & businesses co-operate • The real innovation is not the digital coins themselves, but the trust machine that mints them

11-11-2015 Basic understanding of Bitcoins & its emerging uses What is bitcoin? • Bitcoin is both a type of virtual currency (digital token), & the network on which those tokens can be stored & moved around • Each unit of the virtual currency is nothing more than an entry on a digital ledger, just as most dollars & cents exist

Computer n Communication Technology Page 39 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• Each unit of the virtual currency is nothing more than an entry on a digital ledger, just as most dollars & cents exist only as entries on a bank’s digital ledger • The price of a Bitcoin is set on the open market, generally on exchanges where people offer to buy & sell Bitcoin, similar to the way that a stock’s price is set • Normal currencies are, of course, tracked by banks (& their employees & computer systems) • Bitcoins, in contrast, are kept on a ledger that is maintained & updated by any user of Bitcoin who wants to help • The constantly updated ledger is kept on the computers of all the users — just as Wikipedia entries are written & kept current by the encyclopedia’s users rather than by any central authority • The work maintaining Bitcoin’s ledger is done according to rules that are established by the Bitcoin software • It is the communally maintained ledger on which all Bitcoin accounts & transactions are recorded — known as the blockchain — that makes the currency so different from existing ones • Coz there is no central authority in Bitcoin — just the network of users keeping the records — there is no one to shut down accounts or demand personal information from Bitcoin users • Anyone can open an account & spend whatever Bitcoins they have as long as they have the password (secret key) for their account Where do Bitcoins come from? • From the moment the Bitcoin network started operating in 2009, a new bundle of Bitcoins (initially 50) was released every 10 minutes or so, essentially for free, to one of the computers helping to update & maintain the blockchain ledger • Computers on the network take part in a sort of computational race to win these new coins, a process that came to be called Bitcoin mining • This giveaway provided an incentive for people to join & support the network with their computers • New coins will be released in this way until there are 21 million in the world (currently scheduled to happen sometime in 2140) • Once a user wins a new bundle of Bitcoins he or she can divide them up in any way (up to 8 decimal points) & distribute them to anyone else with a Bitcoin address • Initially, people sent their Bitcoins to friends for free. Now, there are exchanges on which people offer to buy & sell Bitcoins & the price has swung wildly, reaching a high above $1,200 in intraday trading in late 2013 How do you spend a Bitcoin? • Anyone with a Bitcoin address, which is similar to an email address, can send & receive Bitcoins from anyone else with a Bitcoin address • Creating a Bitcoin address is free. Each address comes with a private key, a sophisticated password, that provides access to the coins in the address • There are thousands of merchants that now accept Bitcoin payments online. These companies will generally provide a Bitcoin address where money can be sent in order to complete a transaction • For the merchants, Bitcoin is preferable to credit-card payments coz the merchant doesn’t have to pay a fee to a credit-card company. For consumers with credit cards, there is less of a clear advantage to using Bitcoin Why was Bitcoin so attractive to drug dealers? • The online drug bazaar known as the Silk Road offered a place for vendors to sell illegal goods, like heroin & cocaine, for Bitcoin • Coz Bitcoin can be sent anywhere in the world almost instantly, essentially for free, & coz the payments can be sent without either side knowing the identity of the other, the system is an obvious choice for criminal activity • Law enforcement officials have had some luck in tracking down Bitcoin users by looking at the IP address associated with a particular Bitcoin address, or by tracking down users on the blockchain ledger of all Bitcoin transactions. But this has proved to be a slow & relatively unsuccessful investigative method • The operator of the Silk Road was eventually apprehended, not coz his Bitcoin transactions were traced, but coz he accidentally left his personal email address on a public website • The Silk Road was quickly replaced by imitators that are still flourishing today, offering drugs for Bitcoins Is Bitcoin useful for things besides buying drugs? • The Silk Road helped demonstrate that Bitcoin could be used to send money quickly & cheaply around the world, without requiring a bank account • Slowly, there is increasing interest in using the Bitcoin network as a payment system for legitimate purposes • One often-discussed use is as way for immigrants to send remittances more cheaply to family members overseas who don’t have bank accounts or govt identity cards. This has begun to catch on in places like Argentina, Indonesia & Africa • Other developers have looked to use Bitcoin for very small online payments, of a few cents, which are generally not

• Other developers have looked to use Bitcoin for very small online payments, of a few cents, which are generally not possible in the existing financial system coz of the minimum payments required for credit-card transactions • More recently, financial institutions have grown interested in the idea that the Bitcoin network — & its ledger, the blockchain — allows for direct online transactions of all sorts, even those that don’t involve Bitcoins ○ Banks & financial firms are now looking at using the blockchain to allow for cheaper, faster stock & bond trades

Dogecoin

• Dogecoin is a Litecoin-derived cryptocurrency that features the Shiba Inu (Dog) from the "Doge" Internet meme on its logo. It was introduced on 8 December, 2013. • Dogecoin has a fast initial coin production schedule, compared with other cryptocurrencies. There will be approximately 100 billion coins in circulation by the end of 2014. Thereafter, 5.2 billion coins will be produced per year. • While there are currently few commercial applications for Dogecoin, the currency is gaining traction as an Internet tipping system, in which social media users grant Dogecoin tips to other users for providing interesting or noteworthy content. Dogecoins are associated with the motto "To the moon!". • Dogecoin was created by programmer and former IBM engineer Billy Markus of Portland, . • His hopes were reaching a broader demographic than the investors who made up Bitcoin's economy and something that wouldn't be involved with the controversial history behind Bitcoin (namely its association with the Silk Road). • The currency's popularity and value are rapidly growing. Unlike many popular cryptocurrencies, DOGE is primiarily traded on Crypsy a large US based FinCEN regulated exchange. • Dogecoin functions using public-key cryptography, in which a user generates a pair of cryptographic keys: one public and one private. Only the private key can decode information encrypted with the public key; therefore the keys' owner can distribute the public key openly without fear. The public key is the Dogecoin address to which other users can send Dogecoins. The private key, however, must be kept secret and secure. • Dogecoin community would put together a fund-raising effort aimed at helping Indian athletes reach the Sochi Winter Olympics

Virtual Private Networks 29-04-2014 A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables a computer to send and receive data across shared or public networks as if it is directly connected to the private network, while benefiting from the functionality, security and management policies of the private network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryptions.

VPN connectivity overview A virtual private network connection across the Internet is similar to a wide area network (WAN) link between sites. From a user perspective, the extended network resources are accessed in the same way as resources available within the private network. VPNs allow employees to securely access their company's intranet while traveling outside the office. Similarly, VPNs securely connect geographically disparate offices of an organization, creating one cohesive network. VPN technology is also used by Internet users to connect to proxy servers for the purpose of protecting personal identity and location. VPNs in mobile environments Mobile VPNs are used in a setting where an endpoint of the VPN is not fixed to a single IP address, but instead roams across various networks such as data networks from cellular carriers or between multiple Wi-Fi access points. Mobile VPNs have been widely used in public safety, where they give law enforcement officers access to mission-critical applications, such as computer-assisted dispatch and criminal databases, while they travel between different subnets of a mobile network. They are also used in field service management and by healthcare organizations, among other industries. Increasingly, mobile VPNs are being adopted by mobile professionals who need reliable connections. They are used for roaming seamlessly across networks and in and out of wireless-coverage areas without losing application sessions or dropping the secure VPN session. A conventional VPN cannot survive such events because the network tunnel is disrupted, causing applications to disconnect, time out, or fail, or even cause the computing device itself to crash

Wearable Technology 22-05-2014 Edison: SD-card sized PC

How small a computer can get? If you ask Intel it is already as small as a SD card! Intel has unveiled Edison, a computer housed in an "SD card form factor". The device uses Quark microprocessor technology that was showed by Intel a few months ago. Intel CEO Brian Krzanich said that the "computer" is meant to be used in wearable smart devices like a health tracker or in everyday products like coffee mugs that has to be connected to the internet. Edison has built-in wireless capabilities and support for multiple operating systems. "It is a full system. It's a full Pentium-class PC in the form factor of an SD card," said Krzanich. Edison will be available in the middle of 2014. "Wearables are not everywhere today because they aren't yet solving real problems and they aren't yet integrated with our lifestyles," said Krzanich. "We're focused on addressing this engineering innovation challenge. Our goal is, if something computes and connects, it does it best with Intel inside." In his keynote address at Consumer Electronics Show in Las Vegas Krzanich showed an example of Edison can be used. He said that it can be attached to the clothes of a baby.This will allow parents to monitor the baby even if they are not in the same room. For example, if the coffee mug used by parents also has Edison and can connect to the internet, it can talk to the device attached to the baby's clothes and tell parents whenever the baby is getting uncomfortable.

Edison is Intel's attempt to not repeat the mistake it made in the smartphone market.With smartphones and tablets, Intel failed to see the trend and did not address the market properly until 2012. Now when the companies are

Intel failed to see the trend and did not address the market properly until 2012. Now when the companies are expected to push smartglasses and smartwatches, Intel intends to not repeat the mistake it made earlier. "Most of my career a computer has been something you hold in your hand [...] or sits on your desk... That idea is about to be transformed," said Krzanich. One of Intel's most serious competitors, Qualcomm announced a smartwatch - Toq -- a few months earlier. On Monday, Intel too joined the bandwagon by showing the prototype of the smartwatch it is developing. The company also said that it was developing smart earbuds - called Jarvis -- with biometric and fitness capabilities. The earbuds will read a message to the user or track his physical movement. In addition to developing reference devices for wearable technology, Intel will offer a number of accessible, low-cost entry platforms. These are allegedly aimed at helping lower entry barriers for individuals and small companies to create innovative Internet-connected wearables or other small form factor devices. At his keynote, Krzanich also said that Intel, along with its hardware partners, will launch tablets that dual-boot Windows and Android. The company will make McAfee security app for mobiles and tablets available for free this year. "As corporate bring- your-own-device programs have grown in popularity, many firms have prohibited Android-based devices that weren't compatible with their companies' security requirements. Intel this year will offer Intel device protection technology, which will help Intel-based Android mobile devices meet most security standards for use at home and work," the company said in a press note

19-05-2014 Cassette can store huge data

Storing data on tapes may seem a little antiquated, since the invention of CDs, cloud services and other forms of digital storage, but many businesses and archives around the world continue to do this. And now, by tweaking how it produces the magnetic tape, Sony has created a way not only to boost the potential of the iconic material match to its digital rivals, but to surpass them. The Japanese firm has developed tape for businesses that can store up to 185 terabytes of data – 74 times the capacity of traditional tapes and the equivalent of 3700 Blu-ray discs It could, in theory, be used by anyone but has been designed specifically for organisations that need to store large amounts of data Magnetic tapes with a coating of magnetic powder are used as the mainstream form of tape storage media – with a recording capacity of 2.5TB

Previously, if companies wanted to increase this capacity, they’d need to use technology to shrink the size of the magnetic particles on which data is stored

This can be a tricky and expensive process, and in many cases isn’t cost-effective.

Sony’s new tape consists of a soft magnetic underlayer with a smooth surface created using a vacuum thin film-forming technique called sputter deposition.

Sputter deposition involves shooting argon ions on to polymer film to produce layers of extremely fine crystal particles in a uniform pattern, just 5 micrometres thick.

Until now, when the sputter method was used to create this layer of magnetic particles on a polymer film, it changed the shape and layout of the crystal and made the underlayer feel rough.

This variation in size restricted how much data could be stored on it.

By optimising the sputter technique, as well as developing a smooth, soft magnetic layer, Sony made it possible to shrink the crystals while keeping their shape.

When Sony’s magnetic tape was measured it was found to have a recording density equivalent to about 74 times the capacity of traditional coated tape media used for data storage.

Computer n Communication Technology Page 46 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

capacity of traditional coated tape media used for data storage.

This is also five times the 35TB capacity of the cassette developed by FujiFilm and IBM in 2010.

Sony said it will continue to work towards getting this next-generation storage ready to sell, as well as develop the technology to make it even more efficient, “with the aim of increasing recording densities even further”

Big Data Analytics 12 October 2014 16:50 Dream april 2015-3,

• The ‘big’ of big data is construed as a reference to the sheer volume, velocity (of generation) & variety (of sources) of the datasets involved •

20-05-2014 An R&D Perspective By definition, Big Data, is data whose scale, diversity, and complexity require new architecture, techniques, algorithms, and analytics to manage it and extract value and hidden knowledge from it. In other words, big data is characterised by volume, variety (structured and unstructured data) velocity (high rate of changing) and veracity (uncertainty and incompleteness).

In the Big Data research context, so called analytics over Big Data is playing a leading role. Analytics cover a wide family of problems mainly arising in the context of Database, Data Warehousing and Data Mining research. Analytics research is intended to develop complex procedures running over large-scale, enormous in-size data repositories with the objective of extracting useful knowledge hidden in such repositories. One of the most significant application scenarios where Big Data arise is, without doubt, scientific computing. Here, scientists and researchers produce huge amounts of data per-day via experiments (e.g., disciplines like high-energy physics, astronomy, biology, bio-medicine, and so forth). But extracting useful knowledge for decision making purposes from these massive, large-scale data repositories is almost impossible for actual DBMS-inspired analysis tools. From a methodological point of view, there are also research challenges. A new methodology is required for transforming Big Data stored in heterogeneous and different- in-nature data sources (e.g., legacy systems, Web, scientific data repositories, sensor and stream databases, social networks) into a structured, hence well-interpretable format for target data analytics. As a consequence, data-driven approaches, in biology, medicine, public policy, social sciences, and humanities, can replace the traditional hypothesis- driven research in science.

Big Data: Science & Technology - Challenges Some of the S&T challenges that researchers across the globe and as well as in India facing are related to data deluge pertaining to Astrophysics, Materials Science, Earth & atmospheric observations, Energy, Fundamental Science, Computational Biology, Bioinformatics & Medicine, Engineering & Technology, GIS and Remote Sensing, Cognitive science and Statistical data. These challenges requires development of advanced algorithms, visualization techniques, data streaming methodologies and analytics. The overall constraints that community facing are 1. The IT Challenge: Storage and computational power 2. The computer science : Algorithm design, visualization, scalability (Machine Learning, network & Graph analysis, streaming of data and text mining), distributed data, architectures, data dimension reduction and implementation 3. The mathematical science: Statistics, Optimisation, uncertainty quantification, model development (statistical, Ab Initio, simulation) analysis and systems theory 4. The multi-disciplinary approach: Contextual problem solving

BIG DATA ANALYTICS AND THE INDIA EQUATION To tap the analytics momentum, India now needs to build a sustainable analytics eco-system that brings in a strong partnership across the industry players, government, and academia. Some of the key actions for analytics eco-system in India would be around. 1. Talent Pool - Create industry academia partnership to groom the talent pool in universities as well as develop strong internal training curriculum to advance analytical depth. 2. Collaborate - Form analytics forum across organization boundaries to discuss the pain-points of the practitioner community and share best practices to scale analytics organizations. 3. Capability Development - Invest in long term skills and capabilities that forms the basis for differentiation and value creation. There needs to be an innovation culture that will facilitate IP creation and asset development. 4. Value Creation - Building rigor to measure the impact of analytics deployment is very critical to earn legitimacy within the organization. Big Data and analytics offers tremendous untapped potential to drive big business outcomes. For organizations to

Big Data and analytics offers tremendous untapped potential to drive big business outcomes. For organizations to leverage India as a global analytics hub can be one of the key levers to move up their analytics maturity curve.

23-02-2014 Visitors to Terminal B at Newark Liberty International Airport in New Jersey may notice the bright, clean lighting that now blankets the cavernous interior There is an expanding market for light fixtures capable of capturing and analysing vast amounts of data about the habits of ordinary citizens. Using an array of sensors and eight video cameras around the terminal, the light fixtures are part of a new wireless network that collects and feeds data into software that can spot long lines, recognise license plates and even identify suspicious activity, sending alerts to the appropriate staff. To customers like the Port Authority, the systems hold the promise of better management of security as well as energy, traffic and people. But they also raise the spectre of technology racing ahead of the ability to harness it, running risks of invading privacy and mismanaging information, privacy advocates say. What began as a way to help governments and businesses save energy by automatically turning lights on and off has become an expanding market for lights, sensors and software capable of capturing and analysing vast amounts of data about the habits of ordinary citizens. The light fixtures are outfitted with special chips and connect to sensors, cameras and one another over a wireless network. Data that is collected — say, a particular car pulling up to the terminal —can then be mined and analysed for a broad range of applications. Las Vegas is testing a street lighting system that can broadcast sound, and plans to use it mainly to control lighting and play music or to issue security alerts at a pedestrian mall. Copenhagen, Denmark, is installing 20,000 street lamps as part of a system that could eventually control traffic, monitor carbon dioxide levels and detect when garbage cans are full. Other government agencies and businesses have begun replacing thousands of lighting fixtures with LEDs, mainly to cut costs. The system could, once software is developed, also make shopping more convenient — a potential boon for malls losing business to the Internet. Sensing a shopper pulling into a parking lot, the system could send an alert to a smartphone, showing empty spaces, or a coupon. “We see outdoor lighting as the perfect infrastructure to build a brand-new network,” said Hugh Martin, Sensity’s chief executive. “We felt what you’d want to use this network for is to gather information about people and the planet.”

But that is precisely what worries privacy advocates.

“There are some people in the commercial space who say, ‘Oh, big data — well, let’s collect everything, keep it around forever, we’ll pay for somebody to think about security later’,” said Justin Brookman, who studies consumer privacy at the Center for Democracy and Technology. “The question is whether we want to have some sort of policy framework in place to limit that.” Even those developing the technology acknowledge the concerns. “I’m not saying that I know the exact balance point, but there is a lot of value, I think, if we do it right, to this information,” Martin said, whether that value is heightening security or helping stores compete with Amazon. In Las Vegas, officials say they are not interested in using the video and audio surveillance capabilities of the system they are testing, called Intellistreets, and are instead looking at the use of audio broadcasting to enhance ambience and safety in public areas. In Copenhagen, the emphasis is on efficiency, said Eric Dresselhuys, an executive vice president of Silver Spring Networks, which designed the network to connect that system. Executives say the potential for the advanced lighting is nearly boundless.

nearly boundless. “No one really wanted the smartphone 20 years ago because they didn’t know they could have it,” said Fred Maxik, founder and chief technology officer of Lighting Science Group, which manufactures LEDs. “And I think the same is true of lighting today: No one knows what lighting is going to be capable of.”

03-05-2015 Big data are used in sports to analyse performance & weaknesses of the opponents

20-05-2015 • According to the optimists, big data — in combination with the Internet of Things (IoT) — promises a future where all important decisions about business, life, & society would be taken purely on the basis of data ○ Human judgment, which is typically partial, flawed, & conflicted — & often distorted by factors that are not measurable, & do not compute, such as moral qualms, or empathy — need never come into the picture ○ This, they believe, would make for greater efficiency, higher productivity, & the optimal utilisation of resources for the greatest good of the greatest number ○ Such decision-making is driven purely by big data analytics. It’s called ‘evidence-based decision-making’. Its semantic twin is ‘actionable information’ • Evidence-based decision-making can & does pay off brilliantly in business operations — this is what enterprise software solutions do, & they were indeed the tech precursors of big data analytics • Besides, big data already plays a major role in the management of infrastructure & industry, not to mention security, military affairs, health, & geopolitics, as the Snowden leaks made amply clear • With the advances in cloud & mobile computing, the non-stop generation of data on a never-before scale is bound to change how humans think, & therefore act & live • Chris Andersen, the former editor-in-chief of Wired magazine, in a widely debated piece titled “The End of Theory: The data deluge makes the scientific method obsolete” says - ○ His logic is that since processing of big data can give us correlations that can predict accurately, causation is no longer relevant ○ So theory, or explanations of the world based on the model of cause & effect (which is how humans have traditionally made sense of the world), are now obsolete ○ In other words, we no longer need to think. Collect data, feed them into the mouth of analytics, & wait for solutions to emerge • The World Economic Forum notes in its 2014 Global Technology Report that data is “a new form of asset class”, adding, “data are now the equivalent of oil or gold. And today we are seeing a data boom rivaling the Texas oil boom of the 20th century & the San Francisco gold rush of the 1800s” • The number of app downloads growing from 10 billion in 2010 to 77 billion in 2014, which many believe is trillions of dollar global opportunity to create value over the next decade • India & BDA ○ “Evidence-based policy-making” & “actionable information” pops up in govt documents & the reports of bodies such as the UN or the World Bank ○ the large pool of English-speaking engineering/ mathematics graduates makes India an attractive destination for the off-shoring of BDA, which Indian tech entrepreneurs are well placed to exploit ○ with several citizen-to-govt transactions, such as passport applications & tax payments migrating online, & the state unwilling to relax its grip on Aadhaar, & plans afoot to digitise medical records, it is clear that Big Data will come to play a major role Threats • And given the billions of dollars — the preferred term is ‘value’ — riding on the so-called ‘information economy’, it is unlikely that the raw material for data manufacture (ie. ‘people’) will have much say in the matter • The exponential growth of big data analytics, & its increasing utilisation in govt policy, is premised on many things, including growth in IT infrastructure, the digital inclusion of those hitherto excluded by poverty, & an overarching colonisation of the analog universe by the digital • Many of us have already voluntarily surrendered our privacy, either for the sake of convenience ○ But privacy — while critical for a functional democracy – is not the only casualty of big data. The graver threat is a digital replay of colonial era exploitation, with data replacing mineral resources & raw materials as the source of value (data colonialism) ○ Data-as-gold metaphor used by the WEF report to draw an analogy btw the flow of raw materials from the colonies to Europe, & the flow of data from the erstwhile colonies to the developed West today

colonies to Europe, & the flow of data from the erstwhile colonies to the developed West today . The objective in both cases is the same: extraction of value . the West has been mining African nations for health data without the Africans benefiting in any way • The philosophical basis of big data, which is rooted in the abstractions of statistics ○ It is well known that statistics grew as a discipline to address the needs of the modern state, which had to administer populations on a big scale ○ In big data, the post-modern state has found a fitting collaborator for monitoring, & pre-emptively controlling, sections of the populations that, in circumstances of prolonged deprivation or injustice, can be prone to unseemly eruptions against those who control the levers of the state • Even the term ‘actionable information’, often invoked in the context of big data, suggests that it is not humans who have to decide what is to be done, & therefore take responsibility for the choices being made, but somehow the data or information itself which decides (for humanity) the action to be taken. This, finally, is the inescapable social cost of big data analytics • While evidence-based policy-making may be good for business & the tech industry, it is only politics-driven policy- making that can make a positive difference to people’s lives

29-10-2015 Using big data to prevent disease • Eg. Using big data to understand diseases that made it spread is necessary for epidemic prevention

13-12-2015 Open data revolution • Given the astonishing scale of the data deluge, not much has been achieved. The reasons might be- ○ the data that have been made available are often useless ○ the data engineers & entrepreneurs who might be able to turn it all into useful, profitable products find it hard to navigate ○ too few people are capable of mining data for insights or putting the results to good use ○ it has been hard to overcome anxieties about privacy The privacy problem • The thorniest problem for open data now is privacy • Govts rushing to release individual-level data such as tax, medical or education records are “walking into a massive minefield” • Such data are among the most valuable: they can boost, for eg. precision medicine, which tailors each patient’s treatment. But a privacy scandal can cause a backlash against all open data • Open-data activists have joined forces with bureaucrats & entrepreneurs to sort out all these problems • Some researchers & activists argue that almost all data can be cleverly scrambled to make them anonymous • Others doubt that this can ever be foolproof: as more data are published, it will become easier to mix & match from different sources to figure out who is who • In the end, it will come down to a judgment about how much privacy is worth risking for the sake of better medical treatments, for eg. • Different countries are likely to come to different conclusions: in Sweden, for eg. everyone’s income-tax records are online, including names

Cloud Computing 04 February 2014 20:38 DREAM 2014 March- Page 12,

Uses • Cloud computing has the potential to transform the way IT is consumed & managed, resulting in improved cost efficiencies, accelerated innovation, faster time to-market, & the ability to scale applications on demand • There is a major shift towards the cloud model leading to substantial benefits. However, the legal, contractual, economic & security aspects of cloud computing are evolving & are yet to attain maturity • Across the world, govts in US, UK, the EU, Australia & Singapore see cloud services as an opportunity to improve govt service delivery outcomes by eliminating redundancy, increasing agility & providing information & ICT services at a cheaper cost

‘National Cloud’ Under ‘MeghRaj’ The National Cloud is being implemented by NIC. In order to utilise and harness the benefits of Cloud Computing, Government of India has embarked upon an ambitious initiative – ‘GI Cloud’ which has been named as ‘MeghRaj’. The focus of this initiative is to accelerate delivery of e-services in the country while optimizing ICT spending of the Government. This will ensure optimum utilization of the infrastructure and speed up the development and deployment of eGov applications. The architectural vision of GI Cloud encompasses a set of discrete cloud computing environments spread across multiple locations, built on existing or new (augmented) infrastructure, following a set of common protocols, guidelines and standards issued by the Government of India. Two Policy reports viz., ‘GI Cloud Strategic Direction Paper’ and ‘GI Cloud Adoption and Implementation Roadmap’ have been prepared by the Department of Electronics & Information Technology (DeitY).

The National Cloud will help the departments to procure ICT services on demand in the OPEX model rather than investing upfront on the CAPEX. The Cloud Services available are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS) and Storage as a Service (STaaS). Some of the features of the National Cloud include self service portal, multiple Cloud solutions, secured VPN access and multi location Cloud. NIC is providing Cloud services under the umbrella of ‘MeghRaj’.

Introduction The Government of India has implemented a number of ICT initiatives under the National e-Governance Plan (NeGP), including creation of ICT infrastructure both at the centre and state levels. The infrastructure thus created will provide the basis for adoption of cloud computing for the government with the objective of making optimum use of existing infrastructure, re-use of applications, efficient service delivery to the citizens and increasing the number of e- transactions in the country, thus helping achieve the ultimate goal of NeGP.

To harness the benefits of cloud, Department of Electronics and IT (DeitY) of Government of India has embarked upon an ambitious project termed as ‘GI Cloud’. The ‘GI Cloud’ is the Government of India’s cloud computing environment that will be used by government departments and agencies at the centre and states. In other words, it will enable the government to leverage cloud computing for effective delivery of e-services.

This initiative will comprise the formation and implementation of a cloud computing environment at a national level that will act as a common repository of cloud-based infrastructure resources and applications available on a sharable basis. This will be possible by creating seamlessly operated infrastructure across the country by interconnecting the components of network and data centres while comprehensively addressing all security related aspects. This will, inter- alia, enable Rapid Replication of the successfully implemented applications across the country.

While the GI Cloud initiative will focus on setting up an eco-system for cloud adoption by the Government, leveraging the existing infrastructure, DeitY has established a Working Group headed by Shri Kris. Gopalakrishnan to recommend an overall Policy framework for cloud services in the country.

The need for GI Cloud The National e-Governance Plan (NeGP) has led to the creation of common ICT infrastructure such as State Wide Area Networks (SWANs), State Data Centres (SDCs) and Common Service Centres (CSCs) as well as development of guidelines

Computer n Communication Technology Page 52 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Networks (SWANs), State Data Centres (SDCs) and Common Service Centres (CSCs) as well as development of guidelines and standards to ensure interoperability, standardisation and integration of various services to provide a single face of the government to the people. The progress of NeGP and other national initiatives like National Data Centres (NDCs), NICNET, National Knowledge Network (NKN) and National Optical Fibre Network (NoFN) highlight the fact that core ICT infrastructure has been rolled out and there is considerable reach in terms of connectivity both at the national and state level.

The GI Cloud is envisaged to be established initially on national and state data centre assets (adapted for the cloud through virtualisation) and connected through existing network infrastructure such as the SWANs, NKN, as well as the internet. Based on demand assessment and taking into account security related considerations, government may also engage the services of private cloud providers.

The GI Cloud will provide services to government departments, citizens and businesses through internet as well as mobile connectivity. In addition to accelerating the delivery of e-services to citizens and businesses , the government’s cloud-based service delivery platform will also support a number of other objectives including increased standardisation, interoperability and integration, a move towards an opex model, the pooling of scarce, under-utilised resources and the spread of best practices. It will also support on-going cost effectiveness and manageability.

With cloud computing there is considerable scope of speeding up the development and roll out of e-Governance applications, enhancing agility in customising and deploying ICT to meet specific business needs, while at the same time increasing government ICT efficiency (through re-use and economies of scale).

For realizing this vision and to establish the envisaged cloud computing platform, a well-defined adoption strategy and roadmap are critical.

Definition of cloud computing adopted for GI Cloud The US National Institute of Standards and Technology’s (NIST) definition of cloud computing is the most widely adopted one and has been adopted by the Government of India for GI Cloud.

It states the following: Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

The model defined above comprises of five essential characteristics (viz. on-demand self service, ubiquitous network access, metered use, elasticity and resource pooling), three service models (infrastructure as a service, platform as a service and software as a service), and four deployment models (public cloud, private cloud, community cloud and hybrid cloud). These have been depicted in the figure below.

Key drivers and potential benefits of GI Cloud: • Optimum utilisation of existing infrastructure: The government has already invested in core ICT infrastructure build-up. The GI Cloud can initially be built on the existing infrastructure, or by its augmentation. Cloud computing will enable optimum utilisation of this infrastructure and reduce duplication of cost and effort.

• Rapid deployment and reusability: Applications developed by one entity (for e.g. departments at the centre and states and private organisations) can be made available on the e-Gov AppStore. These applications can be deployed and re-used by other departments with the required customisations. As a result government departments will have the freedom to focus on their core objectives including policy, programs and process improvements or new applications development where a similar application does not already exist.

• Manageability and maintainability: The GI Cloud will provide a single directory of services providing integrated visibility and control helping departments to dispense with the requirement of lengthy procurement and maintenance of ICT infrastructure, an exercise which many find difficult to perform.

• Scalability: Applications and infrastructure deployed on the common GI Cloud platform can take advantage of the virtualised nature of the cloud to scale as required. This essentially becomes more useful for applications where there is a burst of demand for ICT resources at regular intervals.

• Efficient service delivery and agility: Faced with the continued budget challenges all government departments need to find ways to deliver their services to citizens and business as economically as possible without compromising the achievement of desired outcomes. GI Cloud shall provide the framework for government department at the centre and in states to enable roll out of such services much faster compared to current the traditional mode. Easy and quick access to ICT resources will lead to a faster and more agile service delivery of citizen-centric services by the government.

• Security: A security framework for the entire GI Cloud will lead to less environmental complexity and less potential vulnerability. This will also help bring out the essential interoperability across various cloud environments in the country.

• Cost reduction: The pay-per-use model of pricing in cloud will ensure that ICT resources and applications are made available without significant investment in infrastructure purchase and maintenance.

• Ease of first time IT solution deployment: Ease of procurement of software as a service provides an opportunity to agencies going for first time automation to leapfrog as they can buy services directly without going through the entire IT evolution cycle.

• Reduced effort in managing technology: Since most cloud offerings are based on prebuilt standardised foundation of technology that facilitates better support, GI Cloud will reduce government’s effort in managing technology. Easy provisioning of computing resources will ensure more consistent technology upgrades and expedite fulfilment of IT resource requests.

• Increased user mobility: Cloud will facilitate user mobility and collaboration through shared data and applications stored in the cloud when authorised – anytime, anywhere availability.

• Standardisation: There are outstanding issues that are being faced and dealt by all government departments in order to maintain the reliability, portability, security, privacy, and citizen-confidence & trust in government services. GI Cloud shall prescribe the standards around interoperability, integration, security, data security and portability etc. GI Cloud shall consist of framework for citizen services to comply with standard practices, eliminate vendor lock-in scenarios, etc.

Potential risks and issues of GI Cloud: Cloud computing is not a new technology. Rather it is a new model of IT service delivery. As outlined in Gartner’s Hype

Computer n Communication Technology Page 54 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Cloud computing is not a new technology. Rather it is a new model of IT service delivery. As outlined in Gartner’s Hype Cycle for Cloud Computing 2012, most cloud computing technologies and concepts are more than two years from mainstream adoption. This signifies the fact that cloud computing is yet to mature both in terms of technology and business readiness as well as adoption by the market. Issues like standards for security, interoperability, licensing, governance and contracting in cloud are still being deliberated upon and work is in progress worldwide. So, a clear understanding of the associated risks is required for the adoption of cloud computing by the government.

Risks and issues : Cloud standards • Existing cloud standards pertaining to implementation, storage and migration need to be interpreted to understand their applicability for the GI Cloud environment. • Adoption of open standards as per Government of India’s policy on open standards on interoperability and data portability is required in order to reduce the risk of vendor lock-in and inadequate data portability.

Security and privacy • Risk of compromise of confidential information and intellectual property (IP). • Risk of inappropriate access to personal and confidential information. • Appropriate privacy and security measures need to be in place.

Application design • Traditional application design approaches are different from cloud based application design. • All new applications must be designed keeping basic cloud design premises in mind. In order to ensure this, guidelines on application development and design need to be adopted. • Existing applications need to be assessed and if required customised in line with cloud design principles to make them cloud ready.

Integration with legacy environment • In order to have a fully operational cloud environment, cloud based applications need to be integrated with existing onpremise legacy applications. • However the opportunity for customisation of existing applications and services may be limited, leading to increased complexity in integrating with existing legacy environments.

Licensing • Existing software licensing models may not facilitate cloud deployment especially from the point of cloud service delivery. • To facilitate Government departments in deployment of cloud services, a comprehensive framework will be developed on the usage of various licensing models. This framework will be flexible to take into account emerging technologies and business models to leverage the same in the best interest of government.

Location of data • The dynamic nature of cloud may result in uncertainty as to where data actually resides (or where it is in transit) at a given point in time. This raises concerns related to data ownership, accessibility, privacy and security. • The decision regarding storage and transmittal of data to different cloud models may, therefore, be based on application sensitivity, data classification and other relevant privacy and security related considerations including the regulatory and legal framework of the hosting jurisdiction.

Vendor lock-in • Due to the rapid emergence of cloud computing through the initiatives of individual companies, many offerings are proprietary in nature, creating challenges in migrating data and applications to the cloud, or switching cloud providers. This puts customers at significant risk if the need arises for systems to interoperate across cloud and in- house environments or to retrieve data and/or applications if a cloud provider withdraws from the market. These issues are to be managed though appropriate standards and contract provisions.

Portability • Applications developed on one platform may not be portable to, or executable on another.

Computer n Communication Technology Page 55 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Loss of control • Loss of control may lead to resistance to change. As the need to maintain servers and other data centre infrastructure diminishes, the form of the IT function in government may change. • Users may spawn instances unnecessarily and wastefully, just because it is possible and easy.

Funding model • Due to the different funding models like pay-per-use , subscription etc. , some part of ICT capital budgeting will need to be translated into operating expenses (OPEX), as opposed to capital expenditure (CAPEX). This will affect budgeting for ICT and may have an effect on the ICT procurement. • New procurement guidelines, funding and a sustainability model need to be identified to address this.

Performance and conformance • Need to ensure that guaranteed service levels are achieved in the GI Cloud else it may affect effective service delivery. • SLAs are required to be defined for each of the services that will be provided by the GI Cloud. Existing contractual agreements and SLAs both with third part data centre operators, and cloud service providers, may be evaluated and customised to meet the government’s requirements. • For failure to adhere to the service levels, proper penalty clauses must be incorporated. This will require proper interpretation of SLAs. Proper institutional mechanism should be established to resolve any conflict and provide for timely intervention (if required). • A fully functional 24x7 helpdesk may be incorporated.

Skills requirement • A direct result of transitioning to a cloud environment results in demand of resources with different skill sets than those in the traditional environment. • Given that the Government departments are generally understaffed in ICT, this presents an opportunity for requirements identification. A well defined capacity and capability building exercise needs to be carried out across the country to ensure projects do not suffer due to lack of skilled resources. • Ongoing training programmes and plans need to be in place for training existing resources and upgrading their skill set in line with the new requirement.

Change management • More than being a technology, cloud is a new model of service delivery • Adopting cloud across various government departments and agencies at centre and states would call for intensive change management initiatives. The capacity and capability building exercise should incorporate orientation programmes to address these • The procurement teams in state and central nodal agencies need to be trained on procuring for cloud and move away from the traditional experience of procuring hardware and software • Such a comprehensive change management initiative would require proper communication at all levels

Vision To accelerate delivery of e-services provided by the government and to optimise ICT spending of the government.

Policy Government departments at the centre and states to first evaluate the option of using the GI Cloud for implementation of all new projects funded by the government. Existing applications, services and projects be evaluated to assess whether they should migrate to the GI Cloud.

Policy principles: • All government clouds to follow the standards and guidelines set by Government of India • At the time of conceptualisation of any new Mission Mode Project (MMP) or other government project the existing services (IaaS, PaaS, SaaS) of GI Cloud to be evaluated first for usage • All new applications to be cloud ready

Computer n Communication Technology Page 56 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Objective Government of India’s objectives in adopting a cloud computing strategy is as follows: • Optimum utilisation of infrastructure • Speeding up the development and deployment of eGov applications • Easy replication of successful applications across States to avoid duplication of effort and cost in development of similar applications • Availability of certified applications following common standards at one place

GI Cloud Strategy Architectural vision of GI Cloud The architectural vision of GI Cloud focuses on a set of discrete cloud computing environments spread across multiple locations, built on existing or new (augmented) infrastructure, following a set of common protocols, guidelines and standards issued by the Government of India. The GI Cloud services will be published through a single GI Cloud Services Directory. The GI Cloud is envisaged to consist of multiple National and State Clouds. The agencies responsible for operating and managing the National and State Clouds may engage Managed Service Providers (MSPs) for managing the respective cloud computing environments. These cloud computing environments will utilise the existing network infrastructure such as the SWANs, NKN, NOFN integration hubs as well as the internet.

GI Cloud Environment

The figure above depicts an overview of the GI Cloud consisting of cloud computing environments at the national and state levels termed as ‘National Clouds’ and ‘State Clouds’ respectively. While one of the National Clouds will be built utilising the infrastructure available under the National Data Centre(s), other National Clouds may also be established. These may be new or established by augmentation of the existing data centres available at state level. Based on demand assessment and taking into account security related considerations, government may also engage the services of private cloud providers. The willing state clouds built on state data centres can also associate themselves with the GI Cloud and publish their services in the GI Cloud Services Directory.

Services provided by National Clouds would include infrastructure (compute, storage and network), platform, backup and recovery, infrastructure scaling of the State Clouds, application development, migration and hosting etc. Over a period of time, other clouds at the national level could also provide remote infrastructure management for the State

Computer n Communication Technology Page 57 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

period of time, other clouds at the national level could also provide remote infrastructure management for the State Clouds.

The vision is also focussed on national and state level shared, reusable applications and services that will allow any government department or agency to accelerate its eGovernance progress by using applications which other agencies or departments have already developed and made available in the government cloud environment. The National Cloud and each of the other clouds at the national level are envisaged to host an ‘eGov AppStore’ that will act as a common platform to host and run applications at National Clouds which are easily customisable and configurable for reuse by various government agencies/departments at Centre and States without investing effort in development of such applications.

Components of GI Cloud Deriving from the architectural vision, GI Cloud is envisaged to include the following components: • Cloud computing platforms • Common platform to host and run applications - eGov AppStore • GI Cloud Services Directory that will act as the single window or portal for GI Cloud service delivery • Integrated infrastructure acting as a backbone for delivering cloud services • Common set of protocols, guidelines and standards for GI Cloud • The institutional mechanism will consist of an Empowered Committee and Architecture Management Office. DeitY will be the administrative department responsible for implementation and monitoring of the entire GI Cloud initiative. DeitY will be assisted by Expert Group, CoE, Auditors, Cloud Management Office etc. Agencies responsible to operate cloud environments and provide cloud services • Centre of Excellence for cloud computing for awareness building, best practices creation, providing advisory services to the departments on cloud adoption, showcasing the cloud technologies, international collaboration and research and development.

Services to be provided by GI Cloud Infrastructure-as-a-service (IaaS): The GI Cloud will make available compute, storage and network in an on-demand pay-per-use model to potential departments at centre and states.

Platform-as-a-service: The GI Cloud will make available platforms (programming languages and tools for development and testing of applications that are independent of underlying infrastructure) on-demand. Production environment will also be provided for hosting of applications on the GI Cloud.

Software-as-a-service: Applications (core applications and common applications like payment gateway, messaging platform, MIS reporting etc) can be made available in the GI Cloud through the eGov AppStores or in a pure SaaS model. The eGov AppStores will host both cloud and non-cloud enabled applications. Any department can use the services of eGov AppStores through two primary means – either by directly running the application available from the respective eGov AppStore on a virtualised environment (i.e. used as a service) or can also download the application from the respective eGov AppStore. For complex applications that require major modifications to be used by different states, only a productised version of the same whose core is downloadable will be available at the eGov AppStores. However, for generic applications that can be used by multiple departments at centre and states with little or no modification, options will be provided for running the same from cloud or download from the respective eGov AppStore and run.

Data-as-a-service: GI Cloud will also look at data as a service which is similar to SaaS and the data can be provided on demand to the user.

Though the focus has been on pay-per-use or metered usage model of pricing, other pricing models like flat rate pricing (especially for services that are not usage sensitive e.g. DR) or pricing based on different levels of service/usage bands will be explored and suitably incorporated for GI Cloud.

A GI Cloud Services Directory will be created to provide a single window for discovery of services and related information by the consumer.

NIST Definition of Cloud Computing Essential characteristics of cloud computing The Government of India has adopted the following five essential characteristics of cloud computing as defined by NIST, and generally accepted by industry. • On-demand self-service: A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. • Broad network access: Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). • Resource pooling: The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or data centre). Examples of resources include storage, processing, memory, and network bandwidth. • Rapid elasticity: Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. • Measured service: Cloud systems automatically control and optimise resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilised service.

Cloud computing service models The Government of India has adopted the three basic types of cloud service offerings as defined by NIST, and generally accepted by industry.

SaaS The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user specific application configuration settings.

PaaS The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.

IaaS The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).

Cloud computing deployment models There are four basic cloud deployment models, as outlined by NIST, which relate to who provides the cloud services. The Government of India may employ one model or a combination of different models in delivery of applications and business services. Private cloud The cloud infrastructure is provisioned for exclusive use by a single organisation comprising multiple consumers (e.g.,

Computer n Communication Technology Page 59 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

The cloud infrastructure is provisioned for exclusive use by a single organisation comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organisation, a third party, or some combination of them, and it may exist on or off premises.

Community cloud The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organisations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organisations in the community, a third party, or some combination of them, and it may exist on or off premises.

Public cloud The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organisation, or some combination of them. It exists on the premises of the cloud provider.

Hybrid cloud The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardised or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds)

Windows Azure

Windows Azure is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed datacenters. It provides both PaaS and IaaS services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems. Windows Azure was released on February 1, 2010.

Windows Azure infographics-pdf Features Windows Azure is Microsoft's cloud application platform. In June 2012, Windows Azure released the following new features: • Websites allows developers to build sites using ASP.NET, PHP, or Node.js and can be deployed using FTP, Git, Mercurial or Team Foundation Server. • Virtual machines let developers migrate applications and infrastructure without changing existing code, and can run both Windows Server and Linux virtual machines. • Cloud services - Microsoft's Platform as a Service (PaaS) environment that is used to create scalable applications and services. Supports multi-tier scenarios and automated deployments. • Data management - SQL Database, formerly known as SQL Azure Database, works to create, scale and extend applications into the cloud using Microsoft SQL Server technology. Integrates with Active Directory and Microsoft System Center and Hadoop. • Media services - A PaaS offering that can be used for encoding, content protection, streaming, and/or analytics.

The Windows Azure Platform provides an API built on REST, HTTP, and XML that allows a developer to interact with the services provided by Windows Azure. Microsoft also provides a client-side managed class library which encapsulates the functions of interacting with the services. It also integrates with Microsoft Visual Studio, Git, and Eclipse.

Services • Web sites - High density hosting of web sites. This feature was announced in preview form in June 2012 at the Meet Windows Azure event. Customers can create web sites in PHP, .NET, and Node.js, or select from several open source applications from a gallery to deploy. This comprises one aspect of the Platform as a Service (PaaS) offerings for the Windows Azure Platform. • Virtual machines - Announced in preview form at the Meet Windows Azure event in June 2012 the Windows Azure Virtual Machines comprise the Infrastructure as a Service (IaaS) offering from Microsoft for their public cloud. Customers can create Virtual Machines, of which they have complete control, to run the Microsoft Data Centers. As of the preview the Virtual Machines supported Windows Server 2008 and 2012 operating systems and a few distributions of Linux. Since May 2013, the Virtual Machine offering left the preview state and went into General

Computer n Communication Technology Page 60 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

distributions of Linux. Since May 2013, the Virtual Machine offering left the preview state and went into General Availability state (GA). • Cloud services - Previously named "Hosted Services", the Cloud Services for Windows Azure comprise one aspect of the PaaS offerings from the Windows Azure Platform. The Cloud Services are containers of hosted applications. These applications can be internet-facing public web applications (such as web sites and e-commerce solutions), or they can be private processing engines for other work, such as processing orders or analyzing data. • Developers can write code for Cloud Services in a variety of different programming languages; however, there are specific software development kits (SDKs) started by Microsoft for Python, Java, Node.js and .NET. Other languages may have support through Open Source projects. Microsoft published the source code for their client libraries on GitHub. • Data management ○ SQL Database ○ Tables ○ BLOB Storage • Business Analytics ○ SQL Reporting ○ Data Marketplace ○ Hadoop • Identity ○ Active Directory ○ Rights Management ○ Access Control Service • Messaging ○ Windows Azure Service Bus ○ Queues • Media Services • Mobile Services

Implementation Windows Azure uses a specialized operating system, called Windows Azure, to run its "fabric layer" — a cluster hosted at Microsoft's datacenters that manages computing and storage resources of the computers and provisions the resources (or a subset of them) to applications running on top of Windows Azure. Windows Azure has been described as a "cloud layer" on top of a number of Windows Server systems, which use Windows Server 2008 and a customized version of Hyper-V, known as the Windows Azure Hypervisor to provide virtualization of services. Scaling and reliability are controlled by the Windows Azure Fabric Controller so the services and environment do not crash if one of the servers crashes within the Microsoft datacenter and provides the management of the user's web application like memory resources and load balancing.

Reusable Rockets

24-04-2014 SpaceX takes a step towards rocket reuse • the U.S. space company, Space Exploration Technologies (SpaceX), successfully launched its rocket with an unmanned capsule carrying cargo for the International Space Station. The mission also took a step towards making the rocket reusable, with its spent first stage making a controlled descent into the Atlantic Ocean • Much of the human conquest of space has been achieved with ‘expendable launch vehicles,’ rockets that are used just once. Such one-time use has made space travel exorbitantly expensive • Although it was hoped that reuse of the Space Shuttle would lower launch costs, this complex flying machine ended up being more expensive than expendable rockets. • SpaceX, a company established by Internet entrepreneur Elon Musk, is trying a different path for making its rockets capable of undertaking multiple launches. • They are figuring out how to effectively reuse rockets just like airplanes • Through their rocket, attempt is being made to recover it's both stages • returning the first stage is no easy task. The rocket is at a height of about 80 kilometres and travelling at 10 times the speed of sound when the first stage engines shut down and the stage itself separates from the upper stage. The first stage must then be slowed and brought down in a carefully controlled descent. • The first stage had been equipped with four legs intended for a future touchdown on land • , once that stage has finished its job and detached itself from the rest of the rocket, it will fire its engines again. Instead of crashing into the sea, it will make a controlled descent, deploy its legs, slow almost to a stop off the coast • But, if a stage is brought back in this fashion, some of the propellant it carries must be set apart for manoeuvres leading to touchdown. That will reduce amount of payload the rocket can take • The payload that a reusable version carried would be 40% lower than an expendable one. But even with that penalty, reuse would greatly reduce drop launch costs

After they have fired their engines for a few minutes they are left to fall back to Earth, usually splashing ignominiously into the ocean • But a reusable machine would slash the cost of getting into space • several of US’s privately run space firms are planning to use reusable launch vehicles • ultimate goal is to have the first stage fly all the way back to the pad it was launched from, and to land itself facing upwards. It will then be taken away, serviced, refilled with rocket fuel and readied to fly again • being the biggest, the first stage is the most expensive part, so retrieving it should make a huge difference to launch costs • need to recover the second stage, too—though the greater altitude and speed the second stage reaches makes this a far tougher proposition • Some experts opine that launch costs are a small part of the total cost of developing, building & running a satellite network • Reusable rockets can help private business organisations, research institutions and even wealthy private individuals to launch their own customised payloads

to launch their own customised payloads • This would also let human beings colonise space with relatively low cost Challenges • The shuttle itself was intended to fly every week. In the end, it made only 135 trips over the course of 30 years. There is a credible case that it proved more expensive, in the long run, than old-fashioned throwaway rockets would have done. Yet SpaceX has already shaken up an industry once mired in stifling conservatism. A successful fully reusable rocket would just be the latest example in a long tradition of it confounding its critics

Low Earth orbit (LEO)

A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 km (88 min orbital period) & 2,000 km (127 min orbital period) • Objects below 160 km will experience very rapid orbital decay & altitude loss • With the exception of the manned lunar flights of the , all human have taken place in LEO (or were suborbital) • All manned space stations to date, as well as the majority of artificial satellites, have been in LEO Use of LEO • Although the Earth's pull due to gravity in LEO is not much less than on the surface of the Earth, people & objects in orbit experience weightlessness because they are in free fall • A low earth orbit is simplest & most cost effective for a satellite placement & provides high bandwidth & low communication latency • Earth observation satellites & spy satellites use LEO as they are able to see the surface of the Earth more clearly as they are not so far away. They are also able to traverse the surface of the Earth. A majority of artificial satellites are placed in LEO, making one complete revolution around the Earth in about 90 minutes • The International Space Station (ISS) is in a LEO about 400 km above the Earth's surface • Since it requires less energy to place a satellite into a LEO & the LEO satellite needs less powerful amplifiers for successful transmission, LEO is still used for many communication applications ○ Because these LEO orbits are not geostationary, a network (or "constellation") of satellites is required to provide continuous coverage. (Many communication satellites require geostationary orbits, & move at the same angular velocity as the Earth) • Lower orbits also aid remote sensing satellites coz of the added detail that can be gained ○ Remote sensing satellites can also take advantage of sun-synchronous LEO orbits at an altitude of about 800 km & near polar inclination ○ is one example of an Earth observation satellite that makes use of this particular type of LEO • The LEO environment is becoming congested with space debris due to the frequency of object launches • This has caused growing concern in recent years, since collisions at orbital velocities can easily be dangerous, & even deadly • Collisions can produce even more space debris in the process, creating a domino effect, something known as Kessler Syndrome • The Joint Space Operations Center (part of US Strategic Command) currently tracks > 8,500 objects larger than 10 cm in LEO • However, studies suggest that there could be approx. 1 million objects larger than 2 mm, which are too small to be visible from Earth-based observatories

Space debris

the density of space junk around Earth in low-Earth orbit • Since the beginning of space age in 1957, satellite launches & other space missions have left behind a vast amount of junk in space, making it very congested • According to NASA, space debris is a "collection of defunct man-made objects in orbit around Earth - old satellites, spent rocket stages, & fragments from disintegration, erosion, & collisions - including those caused by debris itself' • Most of the orbital debris is within 2,000 km of the Earth 's surface & the gratest concentrations are found at 750-800 km • > 5 lakh pieces of space junk, btw 1-10cm in size, are orbiting the Earth at the moment at a speed of 17,500 miles/hour. The speed is high enough to cause damage to a satellite incase of a collision ○ In Low Earth-orbit, objects travel at 4 miles (7 km) per second. At that speed, even a tiny fleck of paint has heavy impact on collision with other objects ○ This can damage critical components such as pressurised items, solar cells & can also create new pieces of potentially threatening debris • In 2007, China's anti-satellite test, which used a missile to destroy an old , alarmed the world by adding as much as 10% to the debris in Earth's near-space area Damage control • Most of the space debris with size > 4 inches can be tracked & the only biggest threat comes from untrackable debris • The US Dept of Defence maintains a debris monitoring system & informs satellites, including foreign ones, when a collision is imminent • In such a situation, missions are known to conduct "debris avoidance manoeuvers" to dodge incoming debris. But if the tracking devices are not able to spot the debris in time & alert the crew, then the members are advised to shift to a "space lifeboat" called spacecraft, smaller missions that are used to ferry the astronauts to & from the station • The move is meant for damaging collisions" coz it may result in the complete destruction ofthe primary spacecraft The Clean Space One project • A group of Swiss engineers have developed a technology that can "gobble up space junk in a Pac-man-like approach". The "sensitive" project is expected to be launched in 2018

29-06-2014 • NASA estimates that > half a million bits of debris - from defunct satellites to marble-sized fragments like lens covers and copper wire - are orbiting Earth. Millions more are too small to track • Space junk has been recognised as a hazard • Experts agree that the situation has now reached the so-called Kessler Effect - when the number of objects in lower Earth orbit is dense enough that collisions could cause a cascade • The debris field is now acting as a real barrier to operations in the lower Earth orbit which is threatening commerce in inner space, and make launching out of Earth's environment extremely risky • Space junk will orbit for anything btw a few years to a century or more before gradually falling to the atmosphere and burning up Way ahead • There have been more than a dozen proposals, most either made or funded by major space agencies, to speed up the process or destroy the debris remotely • They range from a giant tether that would generate electricity to slow down space junk until it falls into lower orbits to deploying tungsten dust that could, the theory goes, sweep smaller debris into the lower atmosphere. Australian researchers have proposed zapping debris with lasers. Others involve balloons, a solar sail, a wall of frozen water and harpoons

Space Science Page 4 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

and harpoons • None has yet been fully implemented, mostly coz of cost

30-06-2014 • India's PSLV C23 launch was delayed by 3 minutes due to space junk in the low earth orbit to avoid collision

08-09-2014 Robots to protect ISS from deadly junk in lower Earth orbit • Robots are now being employed to protect the International Space Station (ISS) from potentially damaging space junk and help repair defunct satellites • The space laboratory regularly changes orbit to avoid colliding with derelict satellites, rocket stages and other objects whizzing around Earth at huge xspeeds. These robots may fly out to assess the danger presented by the vast array of objects not already tracked by radar.

01-01-2016 • According to NASA, there are over 50,000 pieces of debris (space junk) traveling at speeds up to 17,500 mph around the Earth • The rising population of space debris increases the potential danger to all space vehicles, but especially to the International Space Station, space shuttles & other spacecraft with humans aboard

24-01-2016 Dr.Tilak HR Rise in space junk could provoke armed conflict say scientists • The steady rise in space junk that is floating around the planet could provoke a political row & even armed conflict, according to scientists • Impacts from space junk, especially on military satellites, posed a “special political danger” & may provoke political or even armed conflict btw space-faring nations. The owner of the impacted & destroyed satellite can hardly quickly determine the real cause of the accident • > 23,000 pieces of space junk > 10cm are being tracked, but estimates suggest there could be half a billion fragments ranging from 1cm to 10cm, & trillions of even smaller particles • The junk poses the greatest danger to satellites in low Earth orbit, where debris can slam into spacecraft at a combined speed of > 30,000mph ○ Low Earth orbit which stretches from 100 to 1200 miles above the surface, is where most military satellites are deployed ○ Even tiny pieces of debris have enough energy to damage or destroy military satellites. Even small flecks of paint that have flaked off spacecraft can be hazardous • The warning comes after an incident in 2013 when a Russian satellite, Blits, was disabled after apparently colliding with debris created when China shot down one of its own old weather satellites in 2007 ○ The Chinese used a missile to destroy its satellite, an act that demonstrated its anti-satellite capabilities, & left 3,000 more pieces of debris in orbit • The amount of debris cluttering low Earth orbit has risen dramatically in half a century of spacefaring. Without efforts to clean up the space environment, scientists warns of a “cascade process” in which chunks of debris crash into one another & produce ever more smaller fragments

New planets

Dwarf planets

• Currently there are 5 officially recognised dwarf planets in the solar system • The term was adopted in 2006 to describe objects orbiting the Sun that are neither planets nor natural moons

Pluto's case

19-07-2015 • At a diameter of 1,473 miles, Pluto is slightly larger than what was previously estimated ○ This makes Pluto the biggest dwarf planet (bigger than the dwarf planet Eris), & the largest object in the Kuiper belt (a region filled with chunks of rock & ice that orbit the Sun past Neptune) • In 2006, Pluto was relegated to the status of dwarf planet by the International Astronomical Union which states that a full-fledged planet is an object that orbits the Sun & is large enough to have become round due to the force of its own gravity • Pluto doesn't meet this criteria as its orbit crosses Neptune's orbit, & was thus dropped from the solar system

• NASA’s Dawn Spacecraft studies & sends images of the dwarf planet Ceres (earth's nearest dwarf planet) • It is one of the largest objects in the asteroid belt btw Mars & Jupiter. It almost resembles a planet & hence in 2006, promoted as a “dwarf planet” (a status it now shares with Pluto) • Ceres is also the smallest of the solar system's 5 officially recognised "dwarf planets", the freshly created category into which Pluto was moved. (The other 3 — Haumea, Eris & Makemake — are all, like Pluto, out beyond the orbit of Neptune) • Ceres has all the ingredients needed to have hosted some interesting prebiotic chemistry & could shed light not just on how the solar system got started, but how life did too • Ceres is known to have atleast 25% of water

31-01-2016 Dr.Tilak HR The 9th planet (Planet X)

• Scientists have recently claimed they had found clear evidence of the existence of the 9th planet of the solar system • Scientists are inferring the existence of Planet X from its ghostly gravitational effects on 6 objects beyond Neptune • The planet, they claim, is roughly the size of Neptune & is yet to be spotted. However, other than their calculations, there is no direct evidence that the planet actually exists ○ Based on their calculations, the scientists say the gaseous planet is around 10 times the mass of Earth ○ It is estimated to be anywhere btw 200 & 1,200 times the distance from the Sun to Earth (1 Astronomical Unit or AU), as it has an extremely elliptical orbit ○ The researchers claim that the planet orbits the sun every 15,000 Earth years or so • During the solar system's infancy, 4.5 billion years ago, they say, the planet was knocked out to the extreme outer edges of the solar system where it settled into a distant elliptical orbit, & where it could be found today • What makes a planet? The International Astronomical Union lists 3 criteria for being described as a full-size planet - 1. It is in orbit around the Sun

Space Science Page 8 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

1. It is in orbit around the Sun 2. It has sufficient mass to assume hydrostatic equilibrium, that means it must be large enough to have become round due to the force of its own gravity 3. It has "cleared the neighbourhood" around its orbit — it should have become gravitationally dominant, & there are no other bodies of comparable size other than its own satellites under its gravitational influence . Pluto was downgraded to the status of a dwarf planet coz it did not meet this criteria • Pluto was demoted coz of discovery of Eris in 2005 — which was as big as Pluto, orbited the sun at a distance nearly 3 times greater & was one of many such objects in the Kupier Belt — led to the International Astronomical Union classifying both Eris & Pluto as dwarf planets

02-04-2014 Something new under the sun A miniature planet sheds light on the extremities of the solar system

• MODERN telescopes can see things billions of light-years away, so it may seem surprising that there remains anything to be discovered in the Earth’s backyard. But there is. On March 27th, for example, in a paper published in Nature, Chadwick Trujillo of the Gemini Observatory, in Hawaii, and Scott Sheppard of the Carnegie Institution for Science, in Washington, DC, announced that they have found a new member of the sun’s retinue, in a part of the solar system of which astronomers know little • The object in question, thought to be 450km across and provisionally dubbed 2012VP113, is much farther away than Neptune, the icy world that is the most distant of the sun’s proper planets. Neptune is about 30 astronomical units from the sun (an astronomical unit, or AU, is the average radius of Earth’s orbit, about 150m kilometres). The highly elliptical orbit followed by 2012VP113 brings it no closer to the sun than 80 AU. At its most distant, though this is hard to estimate until more data are available, it may be as much as 500 AU away. • This orbit puts 2012VP113 much farther out even than the Kuiper belt, a collection of icy asteroids beyond the orbit of Neptune in which Pluto (which was booted out of the planetary club in 2006) makes its home. Instead, the two researchers suggest their find is a member of the inner part of the Oort cloud, a collection of dwarf planets, asteroids and comets thought—but not yet proved—to surround the sun, and which may extend as much as half of the four light-year distance to Alpha Centauri. The Oort cloud is believed to be the source of many comets. But some models of how the solar system works suggest there ought to be a gulf of empty space between the Kuiper belt’s edge and the Oort cloud’s beginning, somewhere around 10,000 AU from the sun. Uncomfortably for those models, 2012VP113 sits in that gap. • The Oort-cloud-gap theory has already taken one hit. In 2003 Mike Brown, of the California Institute of Technology, discovered a dwarf planet called Sedna, 1,000km across, travelling in an orbit (see diagram) similar to that of 2012VP113—exactly where it should not have been, in other words. Finding one such body could have been a fluke. A second, though, “strongly suggests that the inner Oort Cloud is real”, according to Megan Schwamb, of the Institute for Astronomy and Astrophysics, in Taiwan, who worked with Dr Brown • Regardless of whether Sedna and 2012VP113 are part of an inner Oort cloud, their weird orbits need explaining. They have probably not been like that from the start. The sun and its retinue condensed from a rotating disc of gas and dust, and anything produced this way should have ended up in a more-or-less circular orbit, such as those the

Space Science Page 9 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

and dust, and anything produced this way should have ended up in a more-or-less circular orbit, such as those the modern planets follow.

One idea is that the two eccentrics were kicked into their orbits by a close encounter with Neptune (which is how the Kuiper belt is thought to have been created). That seems unlikely, though, for both are too far from Neptune for its gravity to have had much influence on them.

Another theory is that they were forced into their current orbits during the solar system’s youth, perhaps by a close encounter with another star that formed in the same nebula as the sun. If so, then they have probably orbited undisturbed ever since, and may thus provide a window onto the earliest years of the solar system.

Elliptical thinking There is, however, a more intriguing possibility. Sedna, 2012VP113 and a handful of smaller objects share similar values of a particular orbital characteristic called the “argument of perihelion”, which describes the angle that their orbits form with the plane of the solar system. Computer models suggest these angles should be randomly distributed. So far, they do not seem to be. And that is a puzzle. According to Drs Trujillo and Sheppard, one possible explanation is that the gravity of something big, distant and unseen is marshalling the orbits of these smaller hunks of rock. The two researchers say their data are compatible with the idea of a giant planet lurking in the far reaches of the solar system.

“Compatible with” is not the same as “proof of”, of course. Unlike the makers of science-fiction films, most astronomers are sceptical of “Planet X” hypotheses, of which there have been plenty over the years. So far only one has proved correct—Neptune itself, whose existence was inferred in the 19th century from irregularities in the orbit of Uranus. But things should become clearer in the not-too-distant future, when new telescopes more capable of spotting dim, distant objects come into operation. When these get going, they will probably find that Earth’s backyard holds plenty more surprises.

24-04-2014 Private space exploration • This is the age of private space exploration, especially in US • The US govt has reduced assistance to NASA & opened the space for private companies • SpaceX, Virigin Galactic etc are companies trying to explore space • Billionaires are donating money for it • Low earth orbit • It might be that private companies are trying to own space • Mining on the moon for Helium 3 for example might get privately owned • We don’t really have laws or regulations in space for private space explorations.

An opposition occurs when the Sun is on one side of the Earth and the object is directly opposite on the other. At opposition, a planet is visible all night, rising around sunset, culminating around midnight and setting around sunrise. Half of the planet visible from the Earth is completely illuminated, the Saturn Opposition occurs after one year.

Space war

29-04-2015 • concern over China developing "disruptive and destructive" counter-space capabilities, which includes both "hard kill" capabilities that was demonstrated by its anti-satellite test in 2007, but also growing space jamming capabilities, which would effect denial of service of US or other satellites • Both the US and erstwhile USSR during the cold war had started on the path of anti-satellite (ASAT) capabilities. But given the "intricate" connection with nuclear deterrence, both countries stepped back. If they had engaged in ASAT development then which could have seen a nuclear explosion in space, it would have spelt the end of manned space missions, or space walks by astronauts since the radiation levels would have rendered it impossible • the space domain is more crowded today, with more countries, including India, becoming capable players in outer space • A related problem is the issue of space debris - China's 2007 ASAT test produced 36,000 pieces of space debris, many of whom have later threatened China's own satellites

30-08-2015 • ISRO’s 2nd consecutive successful launch of GSLV, with an indigenous cryogenic upper stage (CUS) carrying GSAT-6 in Aug 2015 • most of the communication satellites ISRO currently makes are beyond the GSLV-Mk-II’s 2-tonne capability • India’s dependence on foreign space agencies to launch those heavier satellites will continue till the GSLV-Mk-III is tested & declared operational • India spends approximately Rs.500 crore per launch, & the cost is rising with each launch • The global trends reflect an increase in the size of communication satellites & a reduction in the size of earth observation satellites

India's journey

• Isro Propulsion Complex at Mahendragiri in southern Tamil Nadu • Mastering this complex, high performance cryogenic propulsion technology will go a long way in building self reliance for the Indian Space Programme

20-07-2015 India's GSLV-Mark III project aimed at carrying 4-tonne payloads, including future manned missions, has got a boost with Isro successfully test-firing on ground CE-20, the first indigenous high-thrust cryogenic rocket engine • GSLV-Mk III is expected to make its first flight by the end of 2016 • India has so far used 6 of 7 cryogenic engines procured from Russia & needs indigenous engines to fly GSLVs to propel its future space missions • India had developed an indigenous cryogenic stage called CE-7.5 with an engine thrust of 7.5 tonnes • Compared to this, CE-20 will have a higher thrust of 19 tonnes and will be capable of carrying satellites that weigh up to four tonnes • The first flight of a GSLV with the indigenous CE-7.5 cryogenic engine on December 25, 2010 was a failure, but on January 5, 2014 GSLV-D5 (Mk II) used the engine to successfully put in orbit communication satellite GSAT-14 which weighed 1,982kg

National Law for Space- A need

19-07-2015 Experts bat for

Space Science Page 16 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Experts bat for space law • 50 years after it started the space programme & later entered the global market with products & satellite launches, India does not have a space law to protect sovereign, public or commercial interests Why needed • India is among the 5 countries that do not have a space law; while 15 others including the US, Russia, Japan, China, Kazakhstan & Ukraine, have laws based broadly on the of 1967 • A law was needed to ensure that space assets & applications are used for the right causes • As global trends change fast (commercialisation & privatisation of outer space), a clear & comprehensive law will also help a budding to grow • Experts opine that we should have had a national law before ISRO’s international launch services as the country could face huge liabilities ○ As a new set of entrepreneurs had emerged & govt spending in the sector increased, the risk scenario is also changing ○ Today the applications of space programmes have grown tremendously (High resolution images, Broadcasting & Internet) ○ There are 15,000 objects in space orbits [that can threaten working satellites] ○ The future will be much more complex as space tourism gets popular ○ Also in South Asia, India is the only custodian of remote sensing data • Space activities are currently guided by a handful of international space agreements, the Constitution, national laws, the Satellite Communications (SatCom) Policy of 2000 & the revised Remote sensing policy or 2011 • The future national space law can include a regulator, registration & licence of private operators, compensation for harm caused by space objects, insurance, investor disputes, & rescue of space tourists, environmental damage & handling of intellectual property issues

Privatisation of the India’s space programme

12-01-2016 Dr.Tilak HR Space industry enclaves (parks) to come up • Two space industry enclaves or “parks” that have been conceived — one for launchers at Sriharikota & a smaller one at an existing Bengaluru spacecraft campus — signal increased privatisation of the nation’s space programme over the next 5 yrs • ISRO wants to groom & engage domestic industry in the launch vehicles area from integrating sub-systems up to assembling, & even launching the PSLV • The current production works of different parts of launch vehicle are scattered across different industry's respective locations. But the launch industry initiative must be close to ISRO’s launch complex ( Space Centre, at the 145-sq km Sriharikota range), on the lines of the launch complex of Europe’s Arianespace in French Guiana • On the spacecraft front, ISRO plans to increasingly support small & mid-sized industries ○ ISITE, short for ISRO Satellite Integration & Test Establishment, is already open to a few suppliers who assemble & test their spacecraft systems for the ISRO ○ In the coming yrs, more satellites will be needed for replacing the ageing ones in orbit & new advanced communication, Earth observation & navigation spacecraft ○ Industry’s present capacity is unable to meet the increasing launch frequency, for both internal & commercial satellites. Hence a private-public industry consortium initiative is expected to improve industry's capacity & frequency of launches

Astrosat

• It is India’s Multi Wavelength Space Observatory • Astrosat bears instruments looking at the cosmos in 5 frequency bands: the near & far ultraviolet, soft & hard X- rays, & the visible spectrum Analysis • India is not just a provider of scientific talent & cheap launch services to the world’s space efforts, but a scientific partner & a contributor to humanity’s understanding of the universe

27-09-2015

Space Science Page 17 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

27-09-2015 • Astrosat is India’s first astronomy observatory to study distant celestial objects • It carries 5 instruments • Moving in a near Equatorial orbit 650 km above Earth, Astrosat will study black holes, scan the distant universe, star birth regions beyond our galaxy, binary & neutron starts over at least 5 yrs • It will simultaneously observe the sky in multiple light bands or wavelengths of ultraviolet, optical, low & high energy X-ray

29-09-2015 • Astrosat aims at understanding the high energy processes in binary star systems containing neutron stars & black holes, to estimate magnetic fields of neutron stars, to study star birth regions & high energy processes in star systems lying beyond the Milky Way galaxy • The mission also intends to detect new briefly bright X-ray sources in the sky, to perform a limited deep field survey of the universe in the ultraviolet region • The other institutions that participated in the gigantic task of Astrosat launch are Tata Institute of Fundamental Research, Indian Institute of Astrophysics, Inter-University Centre for Astronomy & Astrophysics &

30-09-2015 • Since the Earth’s atmosphere does not allow X-rays & ultraviolet energy from distant cosmic objects to reach ground-based telescopes, space observatories become important to unravel celestial mysteries • Stars & galaxies emit in multiple wavebands • The ability to simultaneously study a wide variety of wavelengths — visible light, ultraviolet & X-ray (both low- & high-energy) bands — has tremendous implications for scientists globally, particularly those in India • It will enable Indian researchers to work in the frontier areas of high-energy astrophysics

Future programs

GSLV Mark III • It is one of the heaviest indigenous launch vehicles that is been developed till date • The vehicle is 42.4 mt tall (other GSLV is 49 mt) • is a three-stage vehicle (also have a passive cryogenic stage/engine) • will also include a unmanned crew module for characterisation of re-entry from the space. India’s dream of sending its astronauts into space shall come true

• shall help ISRO put heavier communication satellites (btw 4,500-5,000 kg.) of INSAT-4 class into orbit • shall enhance India’s capability to be a competitive player in the multimillion dollar commercial launch market • The vehicle envisages multi-mission launch capability for GTO (geo transfer orbit), LEO (low earth orbit), Polar and intermediate circular orbits • The main purpose of the mission is to study the aerodynamics and stability of the rocket • Expenditure: India pays around Rs.500 crore as launch fee for sending up a 3.5 tonne communication satellites whereas the GSLV rocket costs just around Rs.220 crore

05-04-2014 • GSLV-Mark III will carry a 'novel payload' to space as a prelude to manned missions ○ It is an experimental mission to test solid stage S200, liquid stage L110 & cryo stage ○ A crew capsule will also be on board which will help us characterise atmospheric reentry conditions & give us data to validate our own life support systems

02-11-2014

Space Science Page 18 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

02-11-2014 GSLV Mark-III set for partial test flight • GSLV Mark-III is set for its first partial test flight in the first half of December • It also tests features of an unmanned crew module that will be flown down from space and recovered from sea. • In the crew module test ○ the main objective is to look at heating during re-entry and how a vehicle of that size and shape performs in the crucial space phase. ○ The thermal protection systems around the crew module must withstand the [high] temperature ○ A failsafe, parachute-aided descent of the crew module is crucial for flying future Indian astronauts into space and getting them back to Earth safely. • Mark-III can have its first full developmental flight — carrying a full satellite of about 3,500 kg – only when the cryogenic stage is qualified; that could take two to three years. • ISRO now depends on costly foreign launchers to put its 3-tonne communication satellites into space.

Chandrayaan 2

• The Chandrayaan-1 project was instrumental in confirming the presence of water on the lunar surface

• It is an advanced version of the previous Chandrayaan-1 mission to Moon • ISRO’s capability to soft-land on the lunar surface will be demonstrated with this mission • Chandrayaan-2 is configured as a two module system comprising of an Orbiter Craft module (OC) & a Lander Craft module (LC) carrying the Rover developed by ISRO ○ Both the modules are interfaced mechanically by an inter module adapter ○ The Orbiter Craft with payloads onboard will orbit around the moon & perform the objectives of remote sensing the moon. The payloads on the orbiter will conduct mineralogical & elemental studies of the Moon’s surface ○ The Lander Craft with scientific payloads will soft land on the lunar surface at a predetermined location on the lunar surface . The Rover is released by the Lander Craft & has the mission objective of performing mobility activities on low gravity & vacuum of Moon surface with Semi-Autonomous navigation & hazard avoidance capability . The Laser Induced Breakdown Spectroscope (LIBS) & Alpha Particle X-Ray Spectrometer (APXS) payloads onboard Rover would perform elemental analysis of the lunar surface near the landing site

11-05-2014 • The GSLV-Mark II with an indigenous cryogenic engine will put Chandrayaan-2 in orbit in 2017

19-03-2014

• In the case of communication satellites, satellite is usually put at an altitude of 36,000 km above the equator. The satellite would take 24 hours for one revolution, which is equal to what it takes for the Earth too (to rotate on its axis) • If you look at GSLV Mark III, which we are now developing, it is far more powerful compared to GSLV. In GSLV, we can put a 2,200 kg satellite into a geostationary transfer orbit — that means in an orbit where the apogee is 36,000 km and perigee is 200 km — whereas in GSLV Mark III, we can take to the orbit a satellite of 4,000 kg. So that’s almost double the capacity • Perigee means the distance closest to the Earth and apogee is the farthest point • The Mars Orbiter Mission is critical for space exploration. It also shows India’s capability to take a spacecraft to a distance of 400 million km, control it properly there & then conduct experiments ○ The objective of this mission is to prove our technological capability to precisely orbit a satellite around Mars. ○ There have been 51 Mars missions; only 21 were successful ○ Secondly, the scientific objective is to study the presence of methane. Why is methane important? We want to understand the existence of life on Mars Cost & time, both. We have done it at 1/10th the cost

Space Science Page 19 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

○ Cost & time, both. We have done it at 1/10th the cost • we had decided from the seventies that Indian industries, both public and private, are going to be part of us. We also make the best use of the academic community in doing research activities • If you look at the turnover of Antrix, it has been going up. We recently launched a SPOT 6 satellite, one of the best remote sensing satellites in the world, & SPOT 7 is ready to be launched • Antrix has been contributing a lot to the communication satellite programme. A number of satellites of foreign countries are lined up for launch using our PSLV. The recently launched microwave remote sensing satellite… is also going to be used by foreign customers through an arrangement with Antrix

Mission Aditya

• A solar mission to study the Sun • For studying the corona & the solar flares from a low earth orbit

05-04-2014 • Aditya is designed to study sun & its features like coronal emissions

20-09-2015 • ASTROSAT is a multi-wave length observatory capable of studying distant celestial objects & the first dedicated astronomy satellite to be launched by the ISRO

06-03-2015 • ‘NASA-ISRO Synthetic Aperture Radar Mission’ (NISAR), likely to be launched by 2021 ○ this is a high-end satellite that will help in earth observation & monitoring climate change

15-11-2015 India's solar mission 'Aditya' & its importance • Aditya is India’s first dedicated scientific mission to study the sun • It will study the sun’s outer most layers, the corona & the chromosphere, collect data about coronal mass ejection & more, which will also yield information for space weather prediction • The project costs approximately Rs 400 crores & is a joint venture btw ISRO & physicists from Indian Institute of Astrophysics, Bengaluru; Inter University Centre for Astronomy & Astrophysics, Pune; Tata Institute of Fundamental Research, Mumbai, & other institutes • It aims to put a heavy satellite into what is called a halo orbit around the L1 point btw the Sun & the Earth. This point is at a distance of about 1.5 million km from the earth ○ At this point, the satellite can maintain its position with respect to the Sun & the Earth ○ A halo orbit would be a circular orbit around the L1 point . The satellite will have to use its own power (spend energy) to remain in position within in this orbit without losing its way . Such orbits have not been attempted too often Studying the corona • Solar coronagraph is a combination of imaging & spectroscopy in multi-wavelength which will enhance understanding of the solar atmosphere ○ The images will be used to study the highly dynamic nature of the solar corona including the small-scale coronal loops & large-scale Coronal Mass Ejections • The corona is the outermost layer of the Sun & the chromosphere is the second inner layer • The data can help us understand the corona & solar wind, which is a spewing of charged particles into space, at speeds as high as 900 km/s & at about 1 million °C temperature, affecting the environment there • Just like on earth, environment in space changes due to happenings in the sun, such as solar storms (flares). This is known as space weather Impact of space weather • Solar storms & space weather affect satellite operations • They may interfere with electronic circuitry of satellites & also, through enhanced drag (friction effects), impact satellite mission lifetimes • They also impact the positional accuracy of satellites & thus impact GPS navigational networks • Space weather also impacts telecommunications, satellite TV broadcasts which are dependent on satellite-based

Space Science Page 20 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• Space weather also impacts telecommunications, satellite TV broadcasts which are dependent on satellite-based transmission How will Aditya mission help • The data from Aditya mission will be immensely helpful in discriminating btw different models for the origin of solar storms & also for constraining how the storms evolve & what path they take through the interplanetary space from the Sun to the Earth • At the moment, there are models & calculations made by NASA which Indian scientists use to maintain their satellites. Now, there is a possibility of Indians developing their own space weather prediction models

Human Space Flight Mission Programme

• The objective of it is to undertake a human spaceflight mission to carry a crew of two to Low Earth Orbit (LEO) & return them safely to a predefined destination on earth • The programme envisages the development of a fully autonomous orbital vehicle carrying 2 or 3 crew members to about 300 km low earth orbit & their safe return

26-09-2014 MkIII will test the recovery of a dummy crew module from sea. The module is the core of a future Human Space Project, in which a couple of astronauts will fly close to Earth for a few days.

Re-usable Satellite launch vehicle

16-06-2015 • ISRO will flight test an indigenously developed re-usable satellite launch vehicle for the first time in September 2015 • Under the project, a plane will be flown into outer space at 5 times the speed of sound, deliver the payload & then land back like an aircraft • At present, the various stages in a satellite launch vehicle fall off in succession during launch & cannot be reused, making such launches expensive

18-02-2014 GSAT-7 • first Navy satellite to be launched • GSAT-7 is an advanced communication satellite built by ISRO to provide wide range of service spectrum from low bit rate voice to high bit rate data communication • India’s first full-fledged military communications satellite which will be used exclusively by the Navy to shore up secure, real-time communications among its warships, submarines, aircraft and land systems. • GSAT-7/ INSAT-4F is said to significantly improve the country’s maritime security and intelligence gathering in a wide swathe on the eastern and western flanks of the Indian Ocean region

INSAT-3D

INSAT-3D is an advanced weather satellite of India configured with improved imaging System & Atmospheric Sounder • The KALPANA & INSAT-3A satellites of India are operational in geostationary orbit for the past one decade at 74 degree East and 93.5 degree East respectively. • These Satellites have imaging systems providing images in Visible, Near-Infrared, Shortwave Infrared, Water Vapour and Thermal Infrared bands. • INSAT-3D adds a new dimension to weather monitoring through its Atmospheric Sounding System, which provides vertical profiles of temperature (40 levels from surface to ~ 70 km), humidity (21 levels from surface to ~ 15 km) and

Space Science Page 21 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

vertical profiles of temperature (40 levels from surface to ~ 70 km), humidity (21 levels from surface to ~ 15 km) and integrated ozone from surface to top of the atmosphere.

The Imaging System of INSAT-3D has significant improvements over that of KALPANA and INSAT-3A : • Imaging in Middle Infrared band to provide night time pictures of low clouds and fog. • Imaging in two Thermal Infrared bands for estimation of Sea Surface Temperature (SST) with better accuracy. • Higher Spatial Resolution in the Visible and Thermal Infrared bands.

• Also, INSAT-3D carries a Data Relay Transponder and Search and Rescue Transponder. • INSAT-3D will provide continuity to earlier missions and further augment the capability to provide various meteorological as well as search and rescue services

• INSAT-3D has a lift-off mass of 2060 kg, which includes about 1125 kg of propellant. • The propellant carried by INSAT-3D is mainly required to raise the satellite from the Geosynchronous Transfer Orbit (GTO) to its final Geostationary Orbit and to maintain the satellite attitude during its life. • INSAT-3D is based on ISRO’s two Tonne Class platform (I-2K bus) employing light-weight structural elements like Carbon Fibre Reinforced Plastic (CFRP). • The satellite has a solar panel generating 1164 Watts of power. • INSAT-3D is launched into a Geo-synchronous Transfer Orbit (GTO) by Ariane-5 VA-214 launch vehicle from Kourou, French Guiana. The solar panel of the satellite will be deployed immediately after its injection into GTO. • Following this, ISRO‘s Master Control Facility (MCF) at Hassan takes control of the satellite and performs the initial orbit raising maneuvers using the Liquid Apogee Motor (LAM) on-board the satellite, finally placing it in the circular Geostationary Orbit. • Later, INSAT-3D will be put into its final orbital configuration and positioned at 82 deg East longitude. • The designed in-orbit operational life of INSAT-3D is 7 years

09-12-2014 India launches GSAT-16 • GSAT-16 has 48 transponders, the largest number thus far on a communication satellite • GSAT will join a constellation of 10 satellites which forms the Indian National Satellite (INSAT) system • Already we have existing 188 transponders on the INSAT system that broadcast television programmes, provide educational & tele-medicine services, carry telephone conversations & relay data • In addition, close to 95 transponders have been leased on foreign satellites, principally to meet the needs of Direct- To-Home (DTH) television channels • the first indigenously-built INSAT satellites was launched in 1992

IRNSS System

Space Science Page 22 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive IRNSS System

• Once operational by 2016, the IRNSS system will offer navigational services for both civilian & defence purposes in India & 1,500 km beyond its borders • Basic navigational services can take off with just 4 satellites in orbit, ie. 2014 • The XL version of PSLV was earlier used for critical missions like Chandrayaan-1, Mars orbiter mission & the first IRNSS satellite IRNSS-1A, 1B etc. • 'XL' configuration which allows for higher payload • IRNSS system are built for a mission of 10 yrs

05-04-2014 • When Pakistani troops took positions in Kargil in 1999, one of the first things Indian military sought was GPS data for the region, but the US denied it to India. Hence the need arised. • With IRNSS, India can keep a close watch of not just its boundaries, but up to 1,500 km beyond that. It works on a combination of seven satellites which would 'look' at the region from different angles, and, in the process, helps calculate from relative data, real-time movement of objects by as less as 10m. • 3 of the 7 satellites will be in geostationary orbits and the other 4 in inclined geosynchronous orbits. From ground, the 3 geostationary satellites will appear at a fixed point in the sky. However, the 4 geosynchronous satellites moving in inclined orbits in pairs will appear to move in the figure of '8' when 'seen' from ground. • Apart from navigation, the system will help in precise time keeping, disaster management, fleet management and mapping. • Geopolitical needs teach you that some countries can deny you the service in times of conflict. It's also a way of arm twisting. A system run by another country (like GPS) may be switched off in times of crisis leading to complete collapse of certain services.

2 types of services that IRNSS will be offering • Standard Positioning Service (SPS) for civilian use (accuracy of 20m) • Restricted Services (RS) with accuracy of < 10m

Space Science Page 23 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• India will join the small group of nations with their own satellite navigation systems ○ The US GPS, Russian GLONASS & French DORIS. By 2020, the EU’s Galileo & China’s BeiDou satellite arrays are expected to be globally deployed • The need to own secure positioning services is obvious. A major geopolitical incident could render foreign GPS systems hard to access, or impossible to trust • The extra accuracy which the IRNSS promises will assume significance for future developments like the Internet of Things, to revolutionise logistics & inventory management & enhance telemetry services • The Isro is taking a significant step with the IRNSS, helping to future-proof the nation from the perspective of the security & accuracy of data

06-04-2014 • In aerial navigation, aircraft will use the IRNSS satellites when they are cruising, approaching an airport to land or during landing. • will help ships navigate towards their destination through safe and short routes and in guiding them to enter harbours. • In land navigation, drivers of cars and trucks, with a receiver in their mobile phone, can reach their destination through the shortest route • In defence, the IRNSS will help missiles in accurately reaching their targets (circumventing hills). Air-launched missiles will use these satellites to know where they are and head towards their targets. The atomic clocks on the satellites will help missiles in executing their manoeuvres at the appointed time. • The uniqueness of the IRNSS is to have a system with satellites in the geostationary orbit instead of MEO. • For India development of its own navigational system was the need of the hour for civilian, commercial and strategic purposes. • China has committed to provide Pakistan with a ‘military quality’ signal of its BeiDou system (BDS) Concerns • S-band frequency used for first time & problems could arise in miniaturizing the receiver antenna for S-band. • since satellites are at high elevation, they could restrict the system for providing accurate indoor applications

09-10-2015 • The IRNSS would provide self-reliance in the strategically important area of position-related information • India wants to extend its services to SAARC countries • India wants to take IRNSS gradually over the entire globe, may be in less than a decade ○ It could be done by adding a set of regional satellites over adjoining countries ○ India is working towards this with other countries – South Korea & the Gulf nations

21-01-2016 IRNSS- 5th satellite put into orbit • IRNSS is a network of satellites in space-based regional navigation system providing location services over India & neighbouring areas • The IRNSS is ‘regional’ & will cover the area over India & 1,500 km from India’s political boundaries, unlike the GPS which is ‘global’. However, coz it is specific to the Indian region, it is expected to be even more accurate than the GPS. The GPS system uses 24 satellites at present though it can support a constellation of 30 satellites • The IRNSS constellation had already started working after the launch of the 4th satellite in Mar 2015, the minimum number required to make the system operational • GAGAN (GPS-Aided Geo Augmentation Navigation) is meant for navigation services for civil aircraft over the Indian region ○ GAGAN enhances the GPS-derived details of location & time of objects or persons ○ In April 2015, ISRO & the Airports Authority of India also completed GAGAN, focussed on airlines, airports & the civil aviation sector but applicable to land & sea-based services like highways, railways, maritime transport, survey, telecom, etc. • The plan is to integrate IRNSS & GAGAN with Bhuvan (a satellite-based mapping service for the Indian mainland developed by ISRO a few years ago) ○ Both IRNSS & GAGAN would help personal, public & industrial users, from transportation, railways, forestry, farming, agriculture & security

Liquid Apogee Motor (LAM)

11-09-2014 • It is a liquid-propellant engine which is carried on such satellites so that they can be moved from the temporary orbit in which launch vehicles place them to the appropriate operational location ○ This engine was originally developed by the ISRO for its communication satellites ○ Such an engine can be shut off once the spacecraft achieves the desired velocity & fire several times if required, allowing a change of orbit to be achieved with considerable precision ○ A solid-propellant motor, on the other hand, once fired, will continue to operate till the propellants are exhausted ○ The Indian LAM took about 8 years to develop ○ The engine generates a thrust of about 45 kg. Pressurised helium gas drives the propellants, monomethyl hydrazine & a nitrogen tetroxide mixture, from the tanks to the thrust chamber • It also propelled India’s Chandrayaan-1 lunar probe to the Moon & hurled the Mars Orbiter beyond Earth’s clutches ○ Another important development that took place was of a smaller liquid-propellant engine, known as a thruster ○ A spacecraft carries several thrusters that are typically fired in short bursts to correct its orientation & any drift in the orbit

GAGAN, SIMRAN

GAGAN System (GPS Aided Geo-Augmented Navigation) • GAGAN is a joint effort of Airport Authority of India (AAI) & ISRO • In the aviation field, GAGAN will support more direct air routes, reduce fuel consumption & improve safety • In addition, GAGAN provides benefits to agriculture, all modes of transportation & public services such a defence services, security agencies & disaster recovery management by aiding in search & rescue to locate the disaster zone accurately • Since 14th February 2014, GAGAN has been continuously providing navigation signals from GSAT-8 & GSAT-10 satellites launched by ISRO, augmenting the performance of GPS signals received over Indian Airspace • GAGAN was already certified for en route operation since 30th December 2013

14-07-2015

15-01-2015 What is the working mechanism for GAGAN & SIMRAN navigation system? • GAGAN is GPS Aided Geo Augmented Navigation which improves the accuracy of Global Satellite Navigation System (GNSS) receivers • The normal GPS system does not provide the necessary accuracy, integrity etc. required for civil aviation. The GPS system is to be augmented for this • Various countries have different Satellite Based Augmentation Systems (SBAS) & India is having GAGAN • This system consists of 8 Reference Stations called Indian Reference stations, 1 master control centre, 1 • Indian Uplinking Station & a geostationary satellite having GPS transponders namely L1 & L2

Space Science Page 25 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

• Indian Uplinking Station & a geostationary satellite having GPS transponders namely L1 & L2 • The reference stations receive GPS signals as well as signals from geostationary satellite • The signals received at reference stations are sent to master control centre. The master control centre processes this data & computes the corrections for various errors • The corrected messages are formatted for GPS compatibility & sent to the uplinking station. The uplinking station transmits this to geosynchronous satellite for broadcast to user terminals • The reference stations are located at widely distributed locations in India including at Port Blair • The geosynchronous satellite has GPS L1 compatible navigation transponder. Users like aircraft receive this satellite signal along with GPS signals & compute their improved position for navigation • The GAGAN system incorporates ionospheric corrections by studying the ionospheric behaviour & modelling & applying corrections • With this accuracy of < 0.5 mt will be provided by SBAS using GAGAN • GAGAN will offer high accuracies over wide geographical area like Indian airspace. GSAT-8 satellite has the GAGAN payload. This system will be used by the Airport Authority of India for air traffic management • SIMRAN is Satellite Imaging for Rail Navigation ○ This provides real time information to people for accurate train tracking of trains ○ GPS receivers will be installed in trains to get the location of the trains & this information will be sent to a central server which can be accessed by public to find the train location ○ This system has been developed by Research Designs & Standards Organisation (RDSO) in collaboration with IIT- Kanpur

India’s Mars mission 18 February 2014 23:55

• The Mars Orbiter Mission is an expression of India’s interest in planetary science •

• ISRO said the primary objectives of the mission are to demonstrate India’s technological capability to send a satellite to orbit around Mars & conduct meaningful experiments such as looking for signs of life, take pictures of the red planet and study Martian environment. • The satellite will carry compact science experiments, totalling a mass of 15 kg. There will be five instruments to study Martian surface, atmosphere and mineralogy. • After leaving earth orbit in November, the spacecraft will cruise in deep space for 10 months using its own propulsion system and will reach Mars (Martian transfer trajectory) in September 2014. • The 1350 kg spacecraft subsequently is planned to enter into a 372 km by 80,000 km elliptical orbit around Mars. • “We want to look at environment of Mars for various elements like Deuterium-Hydrogen ratio. We also want to look at other constituents — neutral constituents”, ISRO Chairman K. Radhakrishnan

13-09-2014 firing the spacecraft’s propulsion system, 440 Newton engine, to insert the spacecraft into the Martian orbit

25-09-2014

The Mars Orbiter Mission (MOM) owes its success to three of its outstanding features: ISRO's ability to accurately navigate the orbiter towards Mars through a "speedometer" distance of 65 crore km in space, ISRO's expertise in deep space communication and the orbiters built-in autonomy that enabled the spacecraft to take decisions during contingencies. After the Polar Satellite Launch Vehicle (PSLV) put the Mars spacecraft into an earth-bound orbit on

contingencies. After the Polar Satellite Launch Vehicle (PSLV) put the Mars spacecraft into an earth-bound orbit on November 5, 2013, the ISRO navigated with finesse the spacecraft from its earth-bound phase to the sun-centric phase and then the final Martian phase. ISRO was, in other words, able to take the Mars orbiter through a radio distance of 22 crore km over a period of 11 months and successfully slip the orbiter into Martian orbit. As Prime Minister Narendra Modi said in his speech at the Mission Operations Complex-2 here on Wednesday, India successfully navigated the spacecraft "through a route known to very few The huge distances in space entail a significant communication delay. It would take around 20 minutes for a com mand from ground control to reach the spacecraft and another 20 minutes for telemetry information about the health of its systems to be fed back: a round-trip delay of 40 minutes. Communication with the spacecraft was carried out from the MOC-2 and the indigenously-built 30m-diameter antenna installed at Byalalu village near here. To help work around the delayed communication, ISRO equipped the orbiter with the autonomy to take decisions to set anomalies right on its own rather than wait for commands from the ground. The orbiter has sensors and transmitters that can sense "misbehaviour' and switch over to the redundant system on its own.

25-09-2014 The cheapest interplanetary mission ever to be undertaken by the world If one analyses the cost of the Mars Orbiter mission of Rs.450 crore, for Indians it works out to be about Rs.4 per person. Today, a bus ride would cost a lot more. India’s Mars Orbiter mission has paved the way for cheaper and faster inter-planetary probes. If the 20th century witnessed a “space race” between the U.S. and the USSR, the 21st century is seeing an Asian space race. In most aspects of space technology, China is way ahead of India. It has larger rockets, bigger satellites and several rocket ports. It even launched its first astronaut in space way back in 2003 and has a space laboratory in the making. In 2008, when India undertook its first mission to moon Chandrayaan-1, China raced ahead and orbited its Chang’e-1 satellite ahead of India. But in this Martian marathon, India has reached the finish line ahead of China. This now puts India in the pole position as far as Asian Martian exploration goes. In 2012, the first Chinese probe to Mars Yinghuo-1 failed. It was riding atop a Russian satellite called Phobos-Grunt. But the Chinese probe failed to even leave earth. Earlier in 1998, a Japanese probe to Mars ran out of fuel. Challenges ahead Coming up in the next few weeks is the test firing of India’s monster rocket, the Geosynchronous Satellite Launch Vehicle Mk III, a rocket capable of carrying heavy payloads into space. This flight will carry a dummy crew module, which is part of a programme for the development of critical technologies that ISRO seeks to develop as part of its human space flight programme. As ISRO says, the first astronaut could well be a woman. In a few weeks, an Indian navigation satellite will be also launched into space. By 2017, ISRO wants to undertake India’s second mission to moon Chandrayaan-2 which will have an Indian lander and a rover. Subsequently, it also wants to launch dedicated missions to study the Sun and the planetary bodies in the solar system. Criticism “How can poor countries afford space programmes?” The criticism seems partly directed at the fact that the mission was not privately funded, as research in the West increasingly is; state money was channelled towards it without any marketable product emerging. But inquiry and exploration are not the prerogative of advanced capitalist western nations — with the rest of the world eternally condemned to be a footnote in the history of science, even as its historical contributions to knowledge are forgotten. It can be argued that in a better world the search for knowledge and the quest for social justice would be necessarily intertwined. India’s weather satellites helped reduce the number of deaths during cyclone Phailin last year. Recent floods in Kashmir speak of failures, technological and political, to anticipate and respond to natural disasters. Indeed, placing industrial development over ecological interests often causes such disasters in the first place. Serious questions remain about whether science and technology — and not just in poorer countries — can have a greater good in mind when the bottom line is profit. The space race between the U.S. and the Soviet Union was not an affordable luxury undertaken for the sake of knowledge, but intrinsically tied to the military-industrial complex. Perhaps national science and technology policy can be fully prised away from corporate and defence industry interests, and placed firmly in the province of economic justice and social progress. India is fortunate in having a long and diverse history of campaigning science movements that have sought to draw both on indigenous knowledge traditions and direct modern scientific research towards progress in health, literacy, environment, nutrition and sanitation. The best way for India to commemorate the success of Mangalyaan would be to reopen a national debate about how science and technology can best be harnessed in the widest interests of its

reopen a national debate about how science and technology can best be harnessed in the widest interests of its people.

08-10-2014 How India managed to send MOM into Mars orbit economically? India’s “space venture on a shoestring” was thus made possible not only by less expensive engineering talent willing to work around the clock, but also by using ingenious improvisation to cope successfully with resource constraints and exceptionally tight timelines. ISRO built the final model of the orbiter from the start instead of building a series of iterative models, as NASA does. They limited the number of ground tests. They used components and building blocks from earlier and concurrent missions. They also circumvented the lack of a rocket powerful enough to launch the satellite directly out of the earth’s gravitational pull by having the satellite orbit the earth for a month to build up enough speed to break free from the earth’s gravitational pull

09-02-2014 MAVEN (Mars Atmosphere & Volatile Evolution)

Shall explore the planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind. Scientists will use MAVEN data to determine the role that loss of volatile compounds—such as CO2, NO2, & H2O—from the Mars atmosphere to space has played through time, giving insight into the history of Mars atmosphere and climate, liquid water, and planetary habitability. MAVEN will carry three instrument suites The Particles and Fields Package will characterize the solar wind and the ionosphere of the planet. The Remote Sensing Package will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer will measure the composition and isotopes of neutral ions.

Big Questions for MAVEN How did life begin and evolve on Earth, and has it evolved elsewhere in the Solar System? Microbial life forms have been discovered on Earth that can survive and even thrive at extremes of high and low temperature and pressure, and in conditions of acidity, salinity, alkalinity, and concentrations of heavy metals that would have been regarded as lethal just a few years ago. These discoveries include the wide diversity of life near sea– floor hydrothermal vent systems, where some organisms live essentially on chemical energy in the absence of sunlight. Similar environments may be present elsewhere in the Solar System.

How did the sun's family of planets and minor bodies originate? For the first time in human history we know of planets around other stars and many of those other planetary systems look quite different from our own. Many have a planet like Jupiter, or even bigger, nearest to the Sun. If we are to understand why this is the case, and how likely it is that there are Earth-like planets elsewhere, we need to better understand how planets form.

• Mars could have been, perhaps four billion years ago, a place friendly for life. • major questions about the history of Mars centre on the history of its climate and atmosphere, and how that’s influenced the surface, the geology and on the possibility for life • Planetary scientists believe that young Mars was blanketed with a thick layer of air — heat-trapping carbon dioxide, in particular — that kept it warmer and wetter. Ancient channels on Mars look as if they were carved by flowing water. Atmospheric transformation Sometime between then and now, the atmosphere went away, and Mars today is an airless, frigid desert with average surface temperatures of — 64° Fahrenheit, or — 53° Celsius. The once-bountiful air molecules must have either gone up, escaping into space, or down, transformed by chemical reactions into rock. Hydrogen, the lightest of gases, can simply float away from gravity’s grasp. Heavier molecules like oxygen and carbon dioxide might have been knocked out by particles and radiation streaming from the sun. As the solar wind sweeps by, it is able to strip off the atmospheric gas. To figure out the puzzle of the missing atmosphere, Maven will carefully measure the wisps that remain

Mars One project

Mission & Vision • Mars One is a not-for-profit foundation that will establish a permanent human settlement on Mars in 2023. • The Mars One mission plan consists of cargo missions and unmanned preparation of a habitable settlement, followed by human landings. • In the coming years, a demonstration mission, communication satellites, two rovers and several cargo missions will be sent to Mars • These missions will set up the outpost where the human crew will live and work.

• Human settlement of Mars is the next giant leap for humankind. • Exploring the solar system as a united humanity will bring us all closer together. • Mars is the stepping stone of the human race on its voyage into the universe. • Human settlement on Mars will aid our understanding of the origins of the solar system, the origins of life and our place in the universe. • As with the Apollo Moon landings, a human mission to Mars will inspire generations to believe that all things are possible, anything can be achieved. • The mission design takes into account the expansion of the human colony where a new crew arrive every two years. • Mars One will select and train the human crew for permanent settlement. • The search for Astronauts began in April 2013. • > 78,000 registered for the selection programme within two weeks of its launch Risks & Challenges • The challenge is to identify the risks in every step of the ten year Mission, from astronaut selection through training, from launch to living on Mars. • Mars One has incorporated into its Mission plan a detailed risk analysis protocol, built by highly experienced individuals, some of them with experience at NASA and the ESA. • Ever evolving, ever improving, Mars One is constantly working to reduce the risk of delay and failure at every level. • As is standard in the aerospace industry, every component will be selected for its simplicity, durability, and capacity to be repaired using the facilities that are available to the astronauts on Mars Mars One identifies two major risk categories- Loss of human life: • Human space exploration is dangerous at all levels. • Mars is an unforgiving environment where a small mistake or accident can result in large failure, injury, and death. Every system (and its backup) must function without fail or human life is at risk. • With advances in technology, shared experience between space agencies, what was once a one-shot endeavor becomes routine and space travel does become more viable Cost overruns: • Cost overruns are also not uncommon in large projects in any arena. • The risk for cost overrun in the Mars One Mission is reduced by using existing technologies • This risk analysis profile shall continue to evolve and improve over the years prior to the first humans walking on the planet Mars.

10-05-2014 44 Indians shortlisted for one-way trip to Mars • Mars One is an ambitious private mission (Netherlands-based non-profit organisation Mars One) to send 4 people on a planned one-way trip to Mars in 2024 to colonise the red planet • Ultimately, 6 teams of 4 people will be selected to train from 2015 to 2024 • According to the mission plan, a reliable habitat will be set up on the planet, & crews of 4 will be sent every 2 yrs • The first trip to Mars (carrying 4 candidates) is expected to commence in 2024 & will last for about 8 months. Every 2 years from then, the other candidates will travel until all 24 reach Mars

The science team sifting data from the US space agency's (Nasa) Kepler telescope says it has identified 715 new planets beyond our Solar System. • These planets are all in multi-planet systems; they orbit only 305 stars. • The vast majority, 95%, are smaller than our Neptune, which is four times the radius of the Earth. • Four of the new planets are less than 2.5 times the radius of Earth, and they orbit their host suns in the "habitable zone" - the region around a star where water can keep a liquid state. • The Kepler spacecraft had confirmed the existence of 246 exoplanets. It has now pushed this number up to 961. That is more than half of all the discoveries made in the field over the past 20 years. • These results are based on the first two years of Kepler observations and with each additional year, we'll be able to bring in a few hundred more planets.

Artist's impression: It is now clear that multi-planet systems are common

The habitable zone is the region around a star where water can keep a liquid state

Importance • This is the largest windfall of planets that's ever been announced at one time • These results establish that planetary systems with multiple planets around one star, like our own Solar System, are in fact common • We now know that small planets - planets ranging from the size of Neptune down to the size of the Earth - make up the majority of planets in our galaxy

Kepler 186f orbits a star that is smaller and cooler than our Sun, but at a distance where water would be liquid

Kepler 186f orbits a star that is smaller and cooler than our Sun, but at a distance where water would be liquid The rocky planet, Kepler 186f, is close to the size of Earth and has the potential to hold liquid water, which is critical for life, the team says. Nestled in the Milky Way, it is part of a five-planet system that orbits around a cool dwarf star. It was spotted by the Kepler telescope, which has found nearly 1,000 new worlds since its launch in 2009. Kepler 186f is about 500 light-years away from the Earth. The researchers estimate that is a little bigger than our planet, with a radius that is about 10% larger than ours. Because of its size, the team believes it is a rocky planet. Kepler 186f travels around a small and cool star. Of the five planets in the system, its orbit is furthest out and lasts about 130 days. The team believes that it has the potential to hold water because with this orbital path it does not journey too close to its star for the liquid to boil away or so far out that it would freeze. Scientists call this region the "habitable zone". Prof Kane said: "Even though it is orbiting a star which is very different from our Sun, the planet itself - both in terms of size and the amount of energy it is receiving from its star - is the most similar planet to our Earth that we've yet discovered. The European Space Agency recently approved the development of an orbiting telescope called Plato, which will be tuned specifically to detect true Earth analogues.

11-01-2015 • Scientists found 8 new planets orbiting their stars at distances compatible with liquid water, bringing the total number of potentially habitable “Goldilocks planets” to a few dozen, depending on how the habitable zone is defined • NASA’s Kepler spacecraft, now in its 5th year of seeking planets like earth • As the ranks of these planets grow, astronomers are beginning to plan the next step in the quest to end cosmic loneliness, gauging which hold the greatest promise for life & what tools will be needed to learn about them • Finding Goldilocks planets closer to earth will be the job of TESS, the Transiting Exoplanet Survey Satellite, scheduled to be launched in 2017 • For all of Kepler’s bounty, the exact analogue of Earth, a planet the same size orbiting the same type of star as the sun — “Earth 2.0,” in astronomer parlance — has not yet been found • Planets smaller than 1.6 times the size of Earth (on a line consistent with Earth & Venus), supposed to be made of rocks

Pillars of creation picture taken by Hubble telescope

09-04-2015 • James Webb space telescope shall be a successor to HST

23-04-2015 • The Hubble Space Telescope — a joint venture btw NASA & the European Space Agency (ESA) — was launched in its orbit 552 km above Earth on April 24, 1990 by the space shuttle Discovery • It has provided breathtaking images, produced fundamental discoveries & brought about a paradigm shift in our understanding of the universe • With its 2.4m diameter mirror, HST has observed the universe in a range of wavelengths, from ultraviolet, visible to infrared, & has changed the way astronomers view the universe • Hubble has unlocked the wonders of the universe & placed our world into a context of 100 billion stars in 100 billion galaxies • The Hubble, which has so far travelled > 3 billion miles, has made > 1.2 million observations since 1990 by completing an orbit around the Earth every 97 minutes at a speed of about 8 km/sec

23-04-2015 • Accurately measuring the Hubble constant (H0), the initial rate of expansion of the universe, from which one can determine the age of the universe is a major preoccupation of astronomers ○ One of the key projects of the HST was the determination of H0 more accurately • the HST was instrumental in democratising cutting edge astronomy ○ It allowed, & even encouraged younger scientists to lead interesting projects

23-04-2015 Achievements of HST • One of the first achievements of HST was to determine the rate at which our universe has been expanding ○ This requires an accurate measurement of the distances of far away galaxies, which is almost impossible with ground-based telescopes ○ This was one of the key projects of the telescope, & it was aptly named after Edwin Hubble, the discoverer of the expansion of the universe ○ The observations with HST settled the rate of expansion within 10% accuracy, ushering a new age in astronomy • The clear images taken with HST also helped to pinpoint distant supernovae of a special type that astronomers use to measure distances ○ This allowed the astronomers to measure the distances of even more distant galaxies, or equivalently peer back further in the history of the universe ○ This led to the momentous discovery that our universe is not only expanding, but also accelerating • The crash landing of the comet Shoemaker-Levy 9 on Jupiter gave a unique photo-op for HST in 1994. It was the first time a collision of a comet with Jupiter was studied in detail, a process that is supposed to occur once every few centuries • Another interesting discovery made by HST (in March 2015) in our solar system is that of a subsurface ocean in Ganymede, a Jovian satellite

Space Science Page 35 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Ganymede, a Jovian satellite • Then in 1996, a long exposure photograph of the universe through a hole in Milky Way produced a photograph of numerous galaxies, among which there were some that existed in the very first billion years of the universe ○ It told us how the process of star formation in galaxies first increased & then waned in the last few billion years or so. Astronomers are still trying to understand this evolution • Another revolutionary discovery in astronomy that HST helped to make was that almost every galaxy contains a black hole in its centre. It also appears that the black hole mass is intimately connected to the galaxy mass ○ Does the black hole form first & fix the mass of the galaxy that should form around it, or is it the other way around? It is to be found out • the clarity of HST images & its ability to image in infrared wavelengths has helped astronomers to discover some crucial phases in newly born stars ○ It appears that the birth of stars is marked by a lot of violence, of gas being thrown out at great speed, sometimes in the form of jets

09-12-2015 ESA's LISA Pathfinder to detect gravitational waves

• Hubble telescope is merely the best-known of a clutch of telescopes in orbit around Earth ○ These instruments all look at the cosmos in different ways, but they have one thing in common: their view is restricted to various parts of the electromagnetic spectrum ○ Hubble takes its pictures in & around the visible-light part of the spectrum • LISA Pathfinder (Laser Interferometer Space Antenna) by European Space Agency detects waves of gravity, rather than light, X-rays or gamma rays • Gravitational waves are rippling distortions in space given off when massive bodies are accelerated ○ They are predicted by Einstein’s general theory of relativity ○ Physicists have compelling indirect evidence that they are real. But researchers have never seen a gravity wave directly • Since gravity waves stretch & compress space, one way to spot them is to look for temporary changes in the distance btw 2 fixed objects ○ Some Earth-based experiments, such as LIGO, an American detector, use tuned lasers for this purpose ○ The idea is that passing gravity waves, by distorting the tunnels, will distort the beams’ paths & produce a signal ○ The trouble is that the distortions such instruments are hunting for are tiny. That makes them both hard to see & hard to distinguish from other, more pedestrian effects ○ LIGO’s operators must account for things like passing traffic, logging in distant forests & the constant, almost unnoticeable seismic grumblings of the Earth itself • LISA Pathfinder takes this idea & moves it into space, where things are much quieter

Liquid water in Mars

30-09-2015 New evidence of liquid water on Mars • The discovery of liquid water (in the subsurface) on Mars marks a major milestone in Martian Science • Mars lost its atmosphere 4 billion years ago — & with it, the atmospheric pressure on Mars was reduced to < 1/10th of the atmospheric pressure on Earth, making water chemically unstable on the surface ○ Thus, liquid water is not stable on the Martian surface at present — water can be there either as ice or as water vapour • The discovery of liquid water below the subsurface makes a human mission logistically easier & cheaper, enhances chances of life on Mars, & provides a way to generate rocket fuel on Mars ○ The discovery of water on Mars is significant coz life on Earth has been associated with water ○ The largest cost of interplanetary travel is the cost of escaping Earth’s gravity & the gravity of Mars . The discovery of water on Mars can help pave the way for efficient conversion of the liquid water into oxygen that can be used as rocket fuel for the return trip

Space Science Page 36 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

that can be used as rocket fuel for the return trip ○ In Mars, there is no reason humans cannot live in temperature- & pressure-controlled chambers that are shielded from radiation . The key will be to find resources on Mars that can be used to support humans during their temporary stay there . The discovery of liquid water, perhaps, is a small step towards this broader goal

Gaia Satellite

• The mission will make a very precise 3D map of our Milky Way galaxy • It is Europe's successor to the Hipparcos satellite which mapped some 100,000 stars. • The one billion to be catalogued by Gaia is still only 1% of the Milky Way's total. • But the quality of the new survey promises a raft of discoveries beyond just the stars themselves. • Gaia will find new asteroids, failed stars, and allow tests of physical constants and theories like General Relativity (Einstein's theory of gravity). • Its map of the sky will be a reference frame to guide the investigations of future telescopes. • To get an undisturbed view of the sky, it will be stationed 1.5m km from Earth. • It will generate about 1 petabyte (one thousand million million bytes) of data in five years. • Supercomputing will be needed to prepare the final catalogue expected in about 2020-21.

• As the Earth goes around the Sun, relatively nearby stars appear to move against the 'fixed' stars that are even further away. • Because we know the Sun-Earth distance, we can use the parallax angle to work out the distance to the target star. • But such angles are very small - less than one arcsecond for the nearest stars, or 0.05% of the full Moon's diameter. • Gaia will make repeat observations to reduce measurement errors down to seven micro-arcseconds for the very brightest stars.

Copernicus & its Sentinels- radar system 05-04-2014 EU launches flagship Sentinel satellite project to monitor Earth A Soyuz rocket has launched from French Guiana with the first satellite in the 's new multi-billion-euro Earth-observation programme.

Space Science Page 38 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

Earth-observation programme. The Sentinel-1a spacecraft has been put in orbit on a mission to map the planet's surface using radar. It will be followed by a fleet of other satellites - also called Sentinels - over the next five years. This as it is called is the biggest ever effort to characterise world.

Sentinel-1a will play an important role in responding to natural disasters

When the full satellite system is operational, it will be producing daily some eight terabytes of data to detail the state of Earth's land surface, its oceans and its atmosphere. European nations have so far committed 7.5bn euros (£6.2bn; $10.3bn) to the project. But the vision for Copernicus is that it is unending - that every Sentinel satellite is replaced at the demise of its mission, ensuring there is continuity of information deep into this century. "Once all the Sentinel satellites have been launched, the Copernicus programme will be the most efficient and fullest Earth-observation programme in the world,".

What is Copernicus?

• A project of the EU that is being procured by the European Space Agency • It pulls together all Earth-monitoring data, from space and the ground • It will use a range of spacecraft - some already up there and others newly commissioned • An invaluable contribution to the understanding of how our climate is changing • Important for disaster monitoring and response - earthquakes, floods, fires, etc • The EU will use Copernicus data to help design and enforce policies: fishing quotas, etc

Radar has myriad uses, from monitoring shipping lanes for pollution or icebergs, to mapping land surfaces to track deforestation or the performance of rice production. However, a key use for Sentinel-1a will be in disaster response. Radar is especially good at detecting the extent of flood waters, and this type of image is also regularly employed following major earthquakes to assess the damage to infrastructure. Sentinel-1a will test a new laser-based data-relay system that will be at the heart of the Copernicus system. The technology, developed by German engineers, will not only handle more data than traditional downlinks but speed the

Space Science Page 39 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

technology, developed by German engineers, will not only handle more data than traditional downlinks but speed the information's receipt on Earth. The laser terminal will reduce the access time to data from hours to minutes.

Sentinels watching over Earth

Copernicus uses a range of technologies to get a broad picture of the health status of the planet • Sentinel-1: Radar's advantage is its all-weather observing capability, seeing through cloud • Sentinel-2: Multi-wavelength detectors to study principally land changes • Sentinel-3: Similar to S2, but tuned to observe ocean properties and behaviour • Sentinel-4: High-orbiting atmospheric sensor to give a global perspective on gases such as ozone • Sentinel-5: Low-orbiting, high-resolution atmospheric sensor to help monitor air quality • Sentinel-6: Future European name for the Jason sea-surface height mission with the US

Copernicus and its dedicated Sentinels will start to build continuous, cross-calibrated, long-term datasets. These will be a boon to climate studies. But the EU hopes the data will prove to be a powerful tool also to help design and enforce community-wide polices, covering diverse areas such as fish stocks management, air quality regulation, and keeping track of waste disposal practices.

Radar to forecast flooding

• The UK authorities made extensive use of over the wet winter • Radar scatters away from a satellite very efficiently over water surfaces • This makes it very easy to see those areas that are flooded • Radar is already used to assess the extent of flood inundation • Fast-return Sentinel data will permit flood forecasting as well

Radar to study earthquakes

Radar interferometry reveals fault locations. • Radar imagery is used to monitor how the ground moves over time • In cities, series of pictures can reveal areas subject to subsidence • In quake zones, before and after imagery will pinpoint ruptured faults • Sentinel-1a's production was delayed by the L'Aquila tremor in 2009

Sentinel data super-highway

Sentinel-1a will test the laser-link technology needed for Europe's rapid data-relay system • Current satellites dump data when passing over ground stations • This will be too slow for the expected terabytes of Sentinel data • A European Data Relay System is being devised, to use laser links • Sentinel data will be bounced off overhead satellites in near real-time

• Space is the final holiday frontier • It is one small step for tourists but one giant leap for tourism • Multiple companies are offering sales of orbital and suborbital flights, with varying durations and creature comforts. • Many companies view sub-orbital flights as a money-making proposition • Suborbital flights usually peak at an altitude of 100–160 kilometres • Passengers would experience three to six minutes of weightlessness, a view of a twinkle-free starfield, and a vista of the curved Earth below. • Virgin Galactic and Space Exploration Corporation [SXC] are expected to begin scheduled sub-orbital passenger flights in 12 months time • Packages by SXC are expected to start at around 1 lakh dollars

02-11-2014 Two accidents, even though one was fatal, should not stop private enterprise from going into space • In Oct 2014, uncrewed Antares rocket operated by Orbital Sciences, a company contracted by NASA to fly supplies to the International Space Station (ISS), blew itself up shortly after launch • In Nov 2014, VSS Enterprise, a owned by Virgin Galactic, a firm that hopes to provide wealthy thrill- seekers with flights to the edge of space, crashed during a test flight (1 pilot was killed)

Universe 31 August 2014 19:50

Big Bang

• POLARBEAR is a cosmic microwave background polarization experiment located in the Atacama Desert, developed by an international collaboration

Cosmic inflation theory

18-03-2014 A new look at the Big Bang • The first moments of the Big Bang 13.8 billion years ago was a hyper-expansion of our universe known as inflation • Inflation was first proposed by MIT physicist in 1980 • Inflation proposes that the initial expansion of the universe was caused by a repulsive form of gravity ○ The initial patch of the universe that underwent inflation would have been unbelievably small, about a billionth of the size of a , & then expanded exponentially • BICEP-2 (Background Imaging of Cosmic Extragalactic Polarization) radio telescope at the South Pole, scans cosmic microwave background (CMB) to see existence of gravitational waves (eventually finding proof for Big Bang) • The detection of these gravitational waves represents the last untested element of Albert Einstein’s general theory of relativity, filling in a major gap in our understanding of how the universe was born. • The gravitational waves are ripples that move through space & time, and have been described as the “first tremors of the Big Bang” • Their detection confirms an integral connection btw quantum mechanics & general relativity • Gravitational waves are a feature of the theories of relativity, & cosmic inflation is a feature of quantum mechanics

07-06-2014 Big Bang: Indian physicist says he’s vindicated • Indian astrophysicist Abhas Mitra rubbished the much publicised claim by a team of US-led astronomers that they had obtained "direct" evidence for the Big Bang origin of the universe (based on BICEP2 re • Acc. to cosmic inflation theory, the universe was born in a Big Bang & that its volume increased almost immediately by an unimaginable factor (of 1078) in what is known as "cosmic inflation" • Rejection of the BICEP-2 result was based on exact mathematical proof that the Big Bang universe can expand only with a uniform speed & the model simply does not allow inflationary cosmologies

05-09-2014 Milky Way is a suburb of a supercluster called Laniakea

05-03-2015 No Big Bang, the universe was there all along: studies • Big Bang — the point when the universe as we know it came into being ○ According to a new theory, there was no Big Bang & the universe existed all along, without beginning or end ○ Moreover, the theory also attempts to give an explanation of Dark Matter & Dark Energy — two phenomena that scientists are struggling to understand • It is widely believed that the universe originated some 13.8 billion years ago & the bursting forth of this monstrous entity from a single point is termed the Big Bang ○ The Big Bang appears as a singular point (Hawking-Penrose singularity) in the mathematical equations that define general theory of relativity ○ The laws of physics break down at this point & nothing can be known about what happened before this. In other words, it marks the point of birth of the universe • Now, three scientists have come up with an alternative theory. In their theory, the universe may have existed all along, perhaps with no “beginning” as dramatic as a Big Bang ○ Raychaudhuri equation (RE), which is an important step in deriving the Hawking-Penrose singularity theorems ○ When it is treated in a classical formalism, the equation leads to the singularity. But the singularity vanishes when the particles are treated as quantum particles & the fields are treated as classical ○ This leads to a solution which is the everlasting universe which was not born in a Big Bang ○ In the case of Dark Matter, scientists showed that it arises naturally . in the quantum corrected Raychaudhuri equation, one set of corrections can be interpreted as giving rise to Dark Matter, while the other term was instrumental in preventing the Big Bang-like scenario & giving infinite life to the universe (Dark energy)

Black holes

• Black holes are formed when stars exhaust their 'nuclear fuel' or are 'dead' • They are abyssinian spaces that exert strong gravitational force on everything in their vicinity • The hole is called 'black' coz it absorbs all the light that hits the horizon, reflecting nothing • Chandra is a space telescope named after Chandrasekhar which detects X-rays to study galaxies •

11-01-2016 Dr.Tilak HR Black holes & telescopes to unravel their mysteries [Chandra, Astra-H telescope & Event Horizon Telescope (EHT)]

• Black holes are so dense that its gravitational attraction can stop light (or anything else) escaping from its surface • Black holes are crucial building blocks of the universe • Most galaxies have 1 black hole at their centre- ○ Whether galaxies formed around pre-existing black holes or the holes formed after those galaxies had come into being is not yet known ○ It is suspected that their central black holes help regulate galaxies’ rates of star formation • Black holes (or their surroundings) are often not black- ○ The process of attracting & swallowing matter acts like a giant particle accelerator as the matter spins around the hole

Space Science Page 45 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

the hole ○ As with such accelerators on Earth, this generates electromagnetic radiation, from radio waves to X-rays ○ A big black hole’s neighbourhood, with lots of spinning matter, can thus be very bright indeed ○ That neighbourhood is also a place where space & time themselves are warped more intensely than anywhere else in the observable universe ○ This chaos, & black holes’ restricted dimensions (even the “supermassive” ones in galactic cores are mere millions of kilometres rather than light-years across), makes studying them hard • The point of no return in the vicinity of black holes where matter is circling is called the “event horizon” ○ Chandra is a space telescope named after Chandrasekhar which detects X-rays to study galaxies ○ Japan’s space agency JAXA will launch Astro-H, a telescope that will help detect X-rays of exceptionally high energies ○ As material slips ever closer to the event horizon, the precise details of its X-ray output are a signal of how it is moving. Astro-H will be able to measure this radiation, & thus infer that motion with unprecedented precision ○ This will permit researchers to measure unambiguously, for the first time, how fast a black hole is spinning. That, in turn, permits tests of Einstein’s general theory of relativity that have remained out of reach until now • Event Horizon Telescope (EHT)

○

○ This is designed to capture an image, built up from radio waves, of the Milky Way’s own supermassive black hole, dubbed Sagittarius A* coz it is the brightest radio source in that constellation ○ Sagittarius A* (or, rather, its event horizon) should be about 12m km across ○ The EHT is not a single facility but rather a collaboration btw existing radio telescopes scattered across the world ○ Together, these instruments perform a trick called very long baseline interferometry. At times when they are acting as part of the EHT, they will be pointed simultaneously at Sagittarius A* ○ The data thus gathered will then be shipped to a central facility, on enormous disk drives, & there carefully combined in a way that makes it seem as if they had been collected by a single radio telescope with an aperture nearly as wide as the Earth itself ○ This should solve a number of outstanding mysteries about black holes: precisely how material falls into them, what causes the jets of material that sometimes squirt from near their polar regions, & just how good Einstein’s equations are at describing the most warped spacetime it is possible to see

Dark Matter (DM) & Dark Energy (DE)

• Dark energy makes 73% of total mass-energy content of the universe, dark matter 23% & ordinary matter 4% • Dark energy is accelarating the expansion of universe (it acts opposite of gravity & increases the distances btw the galaxies) • The postulate of Dark Matter was put forward to account for the extreme velocities with which galaxies & clusters of galaxies are observed to be rotating that the gravity generated by their observable matter alone cannot explain • At such speeds they should have been torn apart long ago • It is believed that something that cannot be seen directly with light (electromagnetic radiation, in general) — & hence the name Dark matter — is providing that extra mass, generating the extra gravity, needed to hold them together (more gravity, more speed) • DM dominates the matter in the universe, outweighing all the visible matter by nearly 6 times, but its existence can be inferred only from the gravitational effect it seems to have on visible matter • Though existence of DM is now accepted (gravitational lensing- deflection in the path of light), & it is all around us with varying densities, its nature has remained a mystery • Gravitational lensing is now being used as a tool to map the extent of dark matter

Space Science Page 46 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

27-03-2014 Was dark matter observed in Kolar Gold Field experiments? KGF experiments The KGF experiments were sponsored by the Tata Institute of Fundamental Research (TIFR), were carried out in 2 phases • The 1st phase experiments, during the 1960s-70s, studied cosmic ray neutrino interactions • 2nd, during the 1980s, studied proton decay & set limits on proton’s lifetime The unusual events, which were detected in a long tunnel at a depth of 2.3 km, were seen during both the phases Dark matter observation in KGF experiments? • The handful of unusual events observed in the underground experiments at the Kolar Gold Field (KGF) mines during the 1960-70s & the 1980s, which have remained unexplained to this day, may have been due to the decays of hitherto unseen Dark Matter (DM) particles • Instead of the early interpretation of cosmic ray neutrinos interacting with the surrounding rock & producing a massive particle which subsequently decayed to give rise to these anomalous events • the authors interpret the events to have been caused by the decay of a neutral DM particle with a mass of about 5-10 GeV & with a lifetime of the order of the lifetime of the universe (about 1010 years or 10 billion years)

26-04-2015 • Galaxies appear to be rotating so fast that they should have spun apart long ago, throwing off stars. There just isn't enough gravity to hold a galaxy together, unless you assume that it hides a huge amount of unseen matter — particles that neither emit nor absorb light • Said to be 5 times more abundant than the stuff we can see, dark matter is a crucial component of the theory behind gravitational lensing, which large masses like galaxies can bend light beams & cause stars to appear in unexpected parts of the sky ○ That was the explanation for the spectacular observation of an "Einstein Cross" reported in March 2015 . Acting like an enormous lens, a cluster of galaxies deflected the light of a supernova into 4 images — a cosmological mirage . The light for each reflection followed a different path, providing glimpses of 4 different moments of the explosion . But not even a galactic cluster exerts enough gravity to bend light so severely unless you postulate that most of its mass consists of hypothetical dark matter ○ Gravitational lensing is now being used as a tool to map the extent of dark matter • Most theorists are believe that dark matter consists of WIMPs — weakly interacting massive particles

28-12-2015 Dr.Tilak HR China’s dark matter probe- Dark Matter Particle Explorer (DAMPE)

• Dark Matter gives rise to the otherwise unaccountably fast rotation rates of most galaxies in the universe • However, scientists are yet to detect a single particle of the stuff. They are unsure of its exact nature but calculations suggest that it will be incredibly unreactive & so difficult to detect • DAMPE will therefore look for gamma rays, electrons & high-energy cosmic rays, all of which could hold clues about the nature of dark matter • A similar detector, the Alpha Magnetic Spectrometer, is attached to the International Space Station

Comets 16 October 2014 12:34

Comet ISON

Rosetta space probe on Comet • Approved in 1993 • Launched in March 2004, has travelled 6.2 billion-km journey through space • Composed of an orbiter and lander, 's objectives are to study comet 67P/Churyumov-Gerasimenko in unprecedented detail, using its 21 scientific instruments to study how the comet reacts to a close encounter with the sun • The resulting data will help scientists learn more about the origin & evolution of our solar system & the role comets may have played in bringing water & organic molecules to Earth, creating conditions for the emergence of life.

13-11-2014 Historic landing

• European Space Agency's lander, , made history by successfully landing on the surface of a speeding comet, 67P/Churymov-Gerasimenko — the first time anyone has landed a spacecraft on a comet on Nov 2014 • Meanwhile, the Rosetta spacecraft will remain in orbit around the comet through 2015. The orbiter will continue detailed studies of the comet as it approaches the sun and then moves away • 6 billion km—distance travelled to reach comet • Its goal is to stick with the comet until it passes the sun in August 2015

Importance • this is the first attempt to orbit & land instruments on a space rock at almost zero gravity (a fast-rotating comet with diameter of 5 km) • Though space probes have made contact with comets before, this will be the first full contact study of a comet by a space probe ○ For Eg. In 2005, Nasa’s Deep Impact had lobbed a block of metal into the comet 9P/Tempel 1 to analyse the vapours and dust it raised

Space Science Page 49 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

vapours and dust it raised ○ In 2006, Nasa’s Stardust mission brought back samples & data from the comet 81P/Wild 2 and the asteroid 5535 Annefrank. • It is a big step for human civilisation as it will help humanity to take “a big step” not only in space science, but also in understanding its own origins • comets like 67P hold ice and, if they are found to contain long-chain molecules too, they can provide an alternative explanation for the origin of life

18-11-2014 After exausting its battery power, Philae now anticipates recharging of its solar panels to conduct its last long-term science (LTS) phase, as the comet continues to move closer to the sun

Studying evolution of Solar System • The comet 67P belongs to a group of celestial bodies previously residing in the outer regions of our solar system, but at a certain point of time were pulled into their current orbits by the huge gravity of Jupiter • Hence, having spent billions of years in the frigid peripheries, comets are widely known to have preserved the signatures of astrochemical processes that occurred in interstellar and protostellar (period of the sun’s infancy) environments • The exploration of comets is, therefore, akin to travelling via a time machine and arriving in an era when the Earth did not even exist Origin of Life • Comets are believed to have transported molecules responsible for the origin of life on Earth • Comets are abundant with organic material that has been processed for billions of years in space

Achievement • Despite the numerous conflicts on Earth, the vastness of space gives humans a common sense of oneness, heritage & purpose • Humanity has achieved something extraordinary as it has set a footprint on a time-travelled comet

19-11-2014 Philae finds traces of organic molecules on comet • found traces of organic molecules & a surface much harder than imagined • Some astrophysicists theorise that comets “seeded” our fledgling planet with the beginnings of life-giving water and organic molecules

17-01-2015 • Comets are believed to be primordial clusters of ice & dust left from the building of the Solar System 4.6 billion years ago & astrophysicists believe, comets contain insights into how the planets formed • The mission has been hailed as a landmark in space exploration, bringing together unprecedented feats of navigation & engineering • Early analysis of data sent back by Rosetta suggest that asteroids, & not comets as previously theorised, provided Earth with water

Comet Siding Spring

16-10-2014

• Comet Siding Spring will hurtle past Mars on Oct. 19, coming to within about 139,500 km of the planet. That is almost 1/3rd of the average distance between Earth and Moon

Space Science Page 50 www.facebook.com/groups/abwf4india Facebook Group: Indian Administrative Service ( Raz Kr) RazKr [Live] - https://telegram.me/RazKrLive

almost 1/3rd of the average distance between Earth and Moon • It originated in the Oort Cloud (The Oort Cloud is an extremely distant shell of icy bodies encircling the solar system) • As the comet is coming into the inner solar system for the first time, it will carry the signature of the pristine material out of which the sun and the planets were born some 4.6 billion years back. • Observations of the comet will therefore aid in understanding the origin and evolution of the solar system. • The Oort Cloud comets take thousands to millions of years to return and some do not come back. Whereas ‘Jupiter Family Comets’ in orbits with a periodicity of less than 20 years. • Halley’s Comet, which is thought to have once originated in the Oort Cloud but then settled down in the solar system and lost its pristine nature after circling the sun many times. • Comet ISON, another visitor from the Oort Cloud, broke apart as it passed closed to the sun. • Last year, Observations of Comet ISON last year showed that it was carbon-rich, maybe in the form of organic molecules.

19-10-2014 • MOM spacecraft will have a ringside view of Comet Siding Spring • The comet comes within 1.35 lakh km of Mars, which is very close astronomically

Rosetta space probe on Comet • Approved in 1993 • Launched in March 2004, has travelled 6.2 billion-km journey through space • Composed of an orbiter and lander, Rosetta's objectives are to study comet 67P/Churyumov-Gerasimenko in unprecedented detail, using its 21 scientific instruments to study how the comet reacts to a close encounter with the sun • The resulting data will help scientists learn more about the origin & evolution of our solar system & the role comets may have played in bringing water & organic molecules to Earth, creating conditions for the emergence of life.

Asteroids 04 April 2014 14:52

What Are The Differences Between An Asteroid, Comet, Meteoroid, and Meteorite? Asteroid: A relatively small, inactive, rocky body orbiting the Sun. Comet: A relatively small, at times active, object whose ices can vaporize in sunlight forming an atmosphere (coma) of dust and gas and, sometimes, a tail of dust and/or gas. Meteoroid: A small particle from a comet or asteroid orbiting the Sun. Meteor: The light phenomena which results when a meteoroid enters the Earth's atmosphere and vaporizes; a shooting star. Meteorite: A meteoroid that survives its passage through the Earth's atmosphere and lands upon the Earth's surface.

Size and Frequency Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles. About once a year, an automobile-sized asteroid hits Earth's atmosphere, creates an impressive fireball, and burns up before reaching the surface. Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area.

Only once every few million years, an object large enough to threaten Earth's civilization comes along. Impact craters on Earth, the moon and other planetary bodies are evidence of these occurrences.

Space rocks smaller than about 25 meters (about 82 feet) will most likely burn up as they enter the Earth's atmosphere and cause little or no damage.

If a rocky meteoroid larger than 25 meters but smaller than one kilometer ( a little more than 1/2 mile) were to hit Earth, it would likely cause local damage to the impact area.

We believe anything larger than one to two kilometers (one kilometer is a little more than one-half mile) could have worldwide effects. At 5.4 kilometers in diameter, the largest known potentially hazardous asteroid is Toutatis.

By comparison, asteroids that populate the main asteroid belt between Mars and Jupiter, and pose no threat to Earth, can be as big as 940 kilometers (about 583 miles) across

Asteroid Redirect Mission Asteroid Redirect Mission-pdf NASA has encouraged citizen scientists to send project design & plans to capture asteroids & bring them closer to earth to collect samples from them for further studies. NASA has announced a proposal worth 6 million dollars for this.

Asteroid Sample Retrieval

Asteroid Sample Storage

Robotic Asteroid Redirect Vehicle with Orion

Asteroid Redirect Vehicle with Capture Bag and EVA

The Asteroid Retrieval & Utilization (ARU) mission, also known as the Asteroid Initiative, is a potential future space mission proposed by NASA. Still in the early stages of planning and development, the ARU is a mission to bring a small near-Earth asteroid into lunar orbit, where it could be further analyzed both by unmanned craft & by a future manned mission. NASA hopes to complete the mission, which may take anywhere from six to ten years, in time to accomplish its stated goal of landing humans on an asteroid by 2025

The Asteroid Retrieval and Utilization mission, excluding any manned missions to an asteroid which it may enable, is predicted by a Keck Institute for Space Studies study to cost about $2.6 billion, of which $105 million has been proposed for 2014. NASA Administrator Charles Bolden has stated that: "This mission represents an unprecedented technological feat that will lead to new scientific discoveries and technological capabilities and help protect our home planet."

21-06-2014 NASA identifies candidate for asteroid capture NASA has identified an odd, tiny Near-Earth Object as a valid candidate for its ambitious first-ever asteroid-capture mission scheduled for the 2020s The Asteroid Redirect Mission (ARM) is a proposed spacecraft concept which aims to capture either a small asteroid or a boulder from an asteroid. Astronomers using NASA’s Spitzer Space Telescope measured the size of the asteroid in question, called ‘2011 MD’, at 6 metres in diameter. 2011 MD’s structure appears to contain a lot of empty space and resembles a pile of rubble, according to astronomers. Spitzer’s infrared vision was key to sizing up the asteroid. “From its perch up in space, Spitzer can use its heat-sensitive infrared vision to spy asteroids and get better estimates of their sizes,” said Michael Mommert of Northern Arizona University, Flagstaff, the lead author of the study. The Spitzer results confirm that 2011 MD has characteristics suitable

University, Flagstaff, the lead author of the study. The Spitzer results confirm that 2011 MD has characteristics suitable for the ARM proposal, elevating it to the “valid candidate” level. Valid candidates must have the right size, mass and rotation rate to be feasibly captured by the robotic spacecraft, NASA said. Two other valid candidates have been identified so far

Nanosats 10 June 2014 11:52

10-06-2014 Around 1,000 operational satellites are circling the Earth, some ofthem the size and weight of a large car. In the past year they have been joined by junior offspring: 100 or so small satellites, some of them made up of one or more 10cm (4-inch) cubes. They may be tiny, but each is vastly more capable than Sputnik, the first man-made satellite launched by Russia in 1957. And many more are coming. Space hardware used to cost so much that it was available only to generals, multina- tionals and the most privileged scientists. No more. Many of these nanosats, as small satellites weighing no more than a few kilograms are called, have been launched for small companies, startups and university departments, sometimes with finance raised on crowdfunding websites. Their construction costs can be down in the tens of thousands of dollars, which makes them thousands of times cheaper than today's big satellites. Admittedly, there is much they cannot do, but with that sort of price differential, and some ingenious use of the abilities they do have, they could be surprisingly competitive players on a number of fronts. In the next five years another 1,000 nanosats are expected to be launched. Size does impose limits. Nanosats cannot peer as closely at the Earth or carry out as many experiments as big satellites. But for some jobs that does not matter. The plans that companies already have include using nanosats for monitoring crops, studying the sun and tracking ships and aircraft.
