NEO IAS daily current MAIN TOPICS affairs stands out from other daily current affairs by its exclusive UPSC RED PANDAS prelims focus on aspects that lie in and Why in news? beyond current affairs. Genetic study reveals the endangered red panda is actually two separate species. Red pandas: The red pandais a small arboreal mammal found in the forests of India, Nepal, Bhutan and the northern mountains of Myanmar and southern China. The Red Pandas are called “Living Fossils” as they are the only living member of the Ailuridae mammalian family. In India, it is found in Sikkim, western Arunachal Pradesh, Darjeeling district of West Bengal and parts of Meghalaya. It is also the state animal of Sikkim. Conservation status: NEO IAS 0484-4030104, 9446331522 www.neoias.com|https://www.youtube.com/neoias Page 1 of 5 • IUCN- Endangered • Schedule I of the Indian Wildlife (Protection) Act, 1972 Himalayan red panda and Chinese red panda: Chinese red pandas are found in northern Myanmar as well as south- eastern Tibet, Sichuan and Yunnan provinces in China. Himalayan red pandas are native to Nepal, India, Bhutan and southern Tibet in China. The Himalayan red panda has more white on the face, while the face coat colour of the Chinese red panda is redder with less white on it. Note-The Yalu Zangbu River most likely marks the geographical boundary separating the two species. Threats: • Habitat fragmentation and degradation. • Predation by feral dogs. • Occasional hunting and poaching. Note- Giant pandas are one of the world’s eight bear species. o Status IUCN- Vulnerable RED SNOW OR WATERMELON SNOW Why in news? Over the past few weeks, snow around Ukraine’s Vernadsky Research Base, located off the coast of Antarctica’s northernmost peninsula, has started to take on a red color. More about the news The phenomenon is due to the courtesy of algaecalled Chlamydomonas nivalis that thrives in freezing weather. This red-pigmented algae has the potential to jumpstart a feedback loop of warming and melting, Chlamydomonas nivalis is the most common type of snow algae found in snowfields and mountains across the world. The Greek philosopher Aristotle is believed to be one of the first to give a written account of watermelon snow over 2,000 years ago. Why is the snow turning red? This type of algae is actually a member of the green algae family. It won’t turn red until the weather warms up, the cell’s carotenoids— the same pigment that gives pumpkins and carrots their orange hue—absorb heat and protect the algae from ultraviolet light, almost like sunscreen. In the winter months, they lie dormant. The more sunlight the algae receive, the more it produces the “watermelon red” pigment, which causes the snow to melt faster. The algae produce this tinted sunscreen to keep themselves warm. The report mentions that because the snow becomes darker from the tinge, it absorbs more heat, as a result of which it melts faster. Further, these algae change the snow’s albedo, which refers to the amount of light or radiation the snow surface is able to reflect back. RENEWABLE ENERGY MANAGEMENT CENTRES (REMC) Why in news? Power Minister dedicates 11 renewable energy management centres to nation. Background The governmenthas a target of 175 GW renewable energy (RE) capacity by 2022. But challenges to grid management due to intermittent and variable nature of renewable energy (RE) generation pose impediments to the target. NEO IAS 0484-4030104, 9446331522 www.neoias.com|https://www.youtube.com/neoias Page 2 of 5 Renewable Energy Management Centres (REMC) REMCs are state-of-the-art management centers for renewable energy integration. The REMCs are equipped with artificial intelligence-based RE forecasting and scheduling tools and provide greater visualization and enhanced situational awareness to the grid operators. The government had approved the implementation of the REMCs as a central scheme and had mandated POWERGRID, a Maharatna CPSE under the Ministry of Power, as the implementing agency. These REMCs are being managed by the Power System Operation Corporation of India Ltd (POSOCO) at the regional and national level, and at the state level by State Load Dispatch Centres (SLDC). NATIONAL HANDICAPPED FINANCE DEVELOPMENT CORPORATION (NHFDC) Why in news? Union Minister of Social Justice & Empowerment Shri Thaawarchand Gehlot will inaugurate the week long Exhibition-cum-Fair “EKAM Fest” organised by National Handicapped Finance Development Corporation (NHFDC) under M/o Social Justice & Empowerment EKAM Fest EKAM Fest is an effort for promoting entrepreneurship and knowledge among Divyangjan community, generating awareness among society about potentialities of PwDs.

  • 157-21(5-20-00) Red Snow, Green Snow: It's Truly Spring When Those
    May 20, 2000 BROWSE BROWSE TABLE OF BY YEAR 2000 ISSUES CONTENTS 2000 Vol. 157 No. 21 p. 328 Red Snow, Green Snow It’s truly spring when those last white drifts go technicolor By SUSAN MILIUS Microbiologist Brian Duval hates this part, so let’s just deal with the snickering up front. Yes, he studies yellow snow. He also studies red, green, and orange snow and would love to examine other colors if he were lucky enough to dis- cover them. His palette comes from springtime blooms of algae that live only in deep, persistent snowfields. And yes, even a professional sometimes gets fooled. “I was outside a penguin rookery in Antarctica, and I thought I was collecting this greenish-yellow algae,” recalls the microbiologist now at the Massachusetts Department of Environmental Protection in Worcester. “I was saying, ‘Yeah, yeah, this looks like the stuff.’” When he checked his trea- sures under a microscope, however, he diagnosed the obvious nonalgal origin. “It gets embarrassing,” he admits. Despite the yellow-snow raillery, Duval and his colleagues stay with their studies of snow algae because of the marvels of the chilly lifestyle. Somehow the 350 species of snow algae thrive in the near- freezing, nutrient-poor, acidic, sun-blasted slush of melting snowfields around the world. The algae support a food web in the snow—a world of tiny, wormy, crawly beings as odd as Spielberg-movie creatures. Duval Algal life cycles combine the drama of salmon runs and No, it’s not a murder scene. A the nightmare of icebound explorers.

  • Morphological and Physicochemical Diversity of Snow Algae from Alaska Marta J
    www.nature.com/scientificreports OPEN Morphological and physicochemical diversity of snow algae from Alaska Marta J. Fiołka1*, Nozomu Takeuchi2, Weronika Sofńska‑Chmiel3, Sylwia Mieszawska1 & Izabela Treska1 Snow algae are photosynthetic microbes growing in thawing snow. They usually show various morphological cell types. The aim of this study was to carry out microscopic and spectroscopic analysis of diferent forms of cells of snow algae collected on glaciers in Alaska. Four diferent shapes of algal cells were observed with the use of bright feld LM (Light Microscopy), DIC (Diferential Interference Contrast), EDF (Extended Depth Focus), fuorescence microscopy, and SEM (Scanning Electron Microscopy). The cells exhibited the strongest autofuorescence after the exposure to 365‑nm excitation light, and the intensity difered among the cell types. Zygotes (cysts) showed the most intense fuorescence. Acridine orange staining revealed the acid nature of the algal cells. The use of Congo red and Calcofuor white fuorochromes indicated diferences in the structure of polysaccharides in the cell wall in the individual types of algal cells. FTIR (Fourier‑Transform Infrared Spectroscopy) analyses showed the presence of polysaccharides not only in the algal cells but also in the fxative solution. The presence of polysaccharides in the extracellular algal fraction was confrmed by X‑ray dispersion spectroscopy (EDS), X‑ray photoelectron spectroscopy (XPS), and scanning electron microscopy imaging (SEM). The diferences observed in the structure of the cell wall of the diferent forms of red snow algae prompt further analysis of this structure. Te red or pink color of snow caused by blooms of snow algae is commonly observed during summer in alpine and coastal polar regions.
