IIT Bombay’s new deep learning framework, named SpADANet, enhances damage classification accuracy using limited labels across multiple hurricanes.
The Amazon river is the largest river system in the world, discharging huge volumes of fresh water into the ocean. Scientists from the Center for Atmospheric and Oceanic sciences have explored what would be the effect of the reduction in the Amazon river’s runoff into the ocean. The scientists demonstrate the wide ranging climatic changes that can occur if the river discharges lesser water into the Atlantic ocean.
In a first, scientists from Indian Institute of Technology Ropar (IIT RPR), Rupnagar, University of Edinburgh and Indian Institute of Technology Kharagpur (IIT Kgp) have demonstrated a phenomenon called ‘inverse Marangoni effect’ using nanodroplets of pure water.
When energy is supplied to a fluid, it flows. As this energy is increased the flow becomes turbulent. If the energy is provided through heat, we see buoyancy driven turbulence, where the hotter fluid rises to the top and colder fluid moves to the bottom. A conjecture that explained such buoyancy driven turbulent flows may now be overturned. New insights gained in a study using one the world’s most powerful supercomputer could help better explain such flows.
Scientists from the National Institute of Plant Genome Research have identified a protein that helps bacteria consume fungi.
Bacteria are single cellular life forms that have been on the Earth for approximately 3.5 billion years. In all their time on Earth they have adapted to different climates and region, interacting with all other life forms that subsequently evolved on the planet.
Many important process in the body require the movement of cells. From forming our fingers during the development of an embryo to healing wounds in adults, all are possible due to cell movement. But how does cell know in what direction it should move? A collaborative study from Marine Biological Laboratory (MBL), Woods Hole, USA comprising researchers from NCBS Bangalore, National Institutes of Health and Harvard Medical School, USA, find strong evidence for the ‘cytoskeletal force model’, which is one way of explaining how cells move.
A galaxy supercluster is the largest known structure in the Universe, made of dozens of galaxy clusters, themselves containing thousands of galaxies. The Saraswati Supercluster, discovered this year by a team of Indian scientists, is the largest known galaxy cluster today. It extends over 650 million light years across and weighs more than 20 billion suns would. We caught up with Prof. Joydeep Bagchi, who led the team that discovered Saraswati Supercluster, for a chat about the importance and implications of the discovery.
Researchers from Washington University, St. Louis, USA surveyed Indian households to determine the ease of obtaining education and factors that hinder the process, in the country.
Scientists from the Indian Institute of Science Bangalore devise a computational model to study how cooperation evolves in natural systems - from cells to large mammals. The study finds mobility, which was largely ignored before, plays a key role in the evolution of cooperation. Understanding mobility of cells in a medium could help us understand better the spread of cancer.
In a new study, scientists have found a revegetated coal mine to be an excellent site for long-term storage of carbon.
Coal mining was once the backbone of our energy requirements for the country. Even today, India is the fourth largest producer of coal and has the fifth largest coal reserves in the world. However, once coal has been extracted from a mine, the mines are usually discarded or converted into other industries or tourist attractions.
Captive elephants in the country are used for a range of tasks. From hauling timber in the forests to blessing devotees in the temples, they do it all. In a first-of-its-kind study by researchers at the A.V.C. College, Mayiladuthurai, Tamil Nadu, and Dharmapuram Gnanambigai Government Arts College for Women, Mayiladuthurai, have explored how being forced out of their natural and instinctive behaviour affects these majestic megafauna.
