GENES AND PROTEINS THAT CONTROL THE SECRETORY PATHWAY Nobel Lecture, 7 December 2013 by RANDY SCHEKMAN Department of Molecular and Cell Biology, Howard Hughes Medical Institute, University of California, Berkeley, USA. Introduction George Palade shared the 1974 Nobel Prize with Albert Claude and Christian de Duve for their pioneering work in the characterization of organelles interrelated by the process of secretion in mammalian cells and tissues. These three scholars established the modern field of cell biology and the tools of cell fractionation and thin section transmission electron microscopy. It was Palade’s genius in particular that revealed the organization of the secretory pathway. He discovered the ribosome and showed that it was poised on the surface of the endoplasmic reticulum (ER) where it engaged in the vectorial translocation of newly synthesized secretory polypeptides (1). And in a most elegant and technically challenging investigation, his group employed radioactive amino acids in a pulse-chase regimen to show by autoradiograpic exposure of thin sections on a photographic emulsion that secretory proteins progress in sequence from the ER through the Golgi apparatus into secretory granules, which then discharge their cargo by membrane fusion at the cell surface (1). He documented the role of vesicles as carriers of cargo between compartments and he formulated the hypothesis that membranes template their own production rather than form by a process of de novo biogenesis (1). As a university student I was ignorant of the important developments in cell biology; however, I learned of Palade’s work during my first year of graduate school in the Stanford biochemistry department. -

Optogenetics: Using Light to Control the Brain by Edward S. Boyden, Ph.D
Optogenetics: Using Light to Control the Brain By Edward S. Boyden, Ph.D. Courtesy of the MIT McGovern Institute, Julie Pryor, Charles Jennings, Sputnik Animation, and Ed Boyden. Editor’s note: The brain is densely packed with interconnected neurons, but until about six years ago, it was difficult for researchers to isolate neurons and neuron types to determine their individual roles in brain processes. In 2004 however, scientists, including author Edward S. Boyden, Ph.D., found that the neural expression of a protein, channelrhodopsin-2 (ChR2), allowed light to activate or silence brain cells. This technology, now known as optogenetics, is helping scientists determine the functions of specific neurons in the brain, and could play a significant role in treating medical issues as diverse as sleep disorders and vision impairment. Article available online at http://dana.org/news/cerebrum/detail.aspx?id=34614 1 The brain is an incredibly densely wired computational circuit, made out of an enormous number of interconnected cells called neurons, which compute using electrical signals. These neurons are heterogeneous, falling into many different classes that vary in their shapes, molecular compositions, wiring patterns, and the ways in which they change in disease states. It is difficult to analyze how these different classes of neurons work together in the intact brain to mediate the complex computations that support sensations, emotions, decisions, and movements—and how flaws in specific neuron classes result in brain disorders. Ideally, one would study the brain using a technology that would enable the control of the electrical activity of just one type of neuron, embedded within a neural circuit, in order to determine the role that that type of neuron plays in the computations and functions of the brain. -
Mechanical Aspire
Newsletter Volume 6, Issue 11, November 2016 Mechanical Aspire Achievements in Sports, Projects, Industry, Research and Education All About Nobel Prize- Part 35 The Breakthrough Prize Inspired by Nobel Prize, there have been many other prizes similar to that, both in amount and in purpose. One such prize is the Breakthrough Prize. The Breakthrough Prize is backed by Facebook chief executive Mark Zuckerberg and Google co-founder Sergey Brin, among others. The Breakthrough Prize was founded by Brin and Anne Wojcicki, who runs genetic testing firm 23andMe, Chinese businessman Jack Ma, and Russian entrepreneur Yuri Milner and his wife Julia. The Breakthrough Prizes honor important, primarily recent, achievements in the categories of Fundamental Physics, Life Sciences and Mathematics . The prizes were founded in 2012 by Sergey Brin and Anne Wojcicki, Mark Zuckerberg and Priscilla Chan, Yuri and Julia Milner, and Jack Ma and Cathy Zhang. Committees of previous laureates choose the winners from candidates nominated in a process that’s online and open to the public. Laureates receive $3 million each in prize money. They attend a televised award ceremony designed to celebrate their achievements and inspire the next generation of scientists. As part of the ceremony schedule, they also engage in a program of lectures and discussions. Those that go on to make fresh discoveries remain eligible for future Breakthrough Prizes. The Trophy The Breakthrough Prize trophy was created by Olafur Eliasson. “The whole idea for me started out with, ‘Where do these great ideas come from? What type of intuition started the trajectory that eventually becomes what we celebrate today?’” Like much of Eliasson's work, the sculpture explores the common ground between art and science. -

Held virtually from 12 to 15 January 2021, the eminent scientists will also discuss the latest advances in research and how they can be used to develop solutions to address major global challenges. The Summit will be graced by Singapore’s Deputy Prime Minister and Chairman of NRF, Mr Heng Swee Keat, who will deliver the opening address. The GYSS is a multi-disciplinary event covering the disciplines of chemistry, physics, biology, mathematics, computer science, and engineering. During the event, luminary scientists and technologists will share details of their discoveries by delivering plenary addresses, participating in panel discussions, and engaging with the young scientists in small group discussions. They will also provide mentorship to over 500 young researchers from more than 30 countries. Star-studded panel speaking on a wide range of subjects and issues This year, the GYSS sees 21 speakers, the highest number since the start of the Summit, of whom 17 are speaking at the Summit for the first time. The list includes Nobel Laureates, Fields Medallists, Millennium Technology Prize and the Turing Award winners. -

The damage triggered DNA repair responses, but pro- longed infection resulted in unrepaired DNA breaks and harmed host cell viability.
