New Delhi: Researchers have showed that coastal ecosystems globally are a net greenhouse gas sink for carbon dioxide (CO2), but emissions of methane (CH4) and nitrous oxide (N2O) counteract some of the CO2 consumption by these sinks. From tropical lagoons to polar fjords, from coastal mangrove forests to underwater seagrass communities, many coastlines around the…
New Delhi: Climate change is likely to abruptly push up to 30 per cent species over tipping points as their geographic ranges reach unforeseen temperatures, according to a study. The researchers found that if the planet warms by 1.5 degrees Celsius, 15 per cent of species they studied will be at risk of experiencing unfamiliarly…
New Delhi: The number of deaths worldwide from ischemic stroke is expected to increase to nearly five million by 2030, according to a study. The research, published in the journal Neurology, focused on ischemic stroke, which is caused by a blockage of blood flow to the brain and is the most common type of stroke….
New Delhi: Scientists say the simultaneous events of an exceptionally warm and moist period ushered in by a “warm ice age” approximately 7,00,000 years ago and the expansion of polar glaciers played a critical role in permanently altering the climate cycles on Earth. A European research team including Earth scientists from Heidelberg University, Germany, used recently…
New Delhi: With the robot capable of distinguishing one object from another, it can record the time and date objects enter or leave its view. The researchers then developed a graphical interface to enable users to choose objects they want to be tracked and, after typing the objects’ names, search for them on a smartphone…
New Delhi: Symptomatic long COVID may be associated with self-perceived cognitive difficulties such as memory problems, according to a study. Long COVID is described as experiencing persistent symptoms of the disease more than four weeks after initial infection. Researchers at the University of California, Los Angeles (UCLA) in the US noted that over one in three…
New Delhi: Heatwaves in India are becoming more frequent and severe due to climate change, with over 90 percent of the country in the “extremely cautious” or “danger zone” of their impacts, according to a new study. The study, conducted by Ramit Debnath and colleagues at the University of Cambridge, also revealed that Delhi is particularly…
New Delhi: Researchers have identified a gene in multiple mammalian species that could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. The team at Washington State University (WSU) in the US identified expression of the gene, Arrdc5, in the testes of mice, pigs, cattle and humans. When they…
New Delhi: Atmospheric scientists have developed a new way of measuring wind by creating an algorithm that uses water vapour movement data, that could help predict extreme events such as hurricanes and storms. The researchers from University of Arizona, US, got the water vapour data from the two operational satellites of the National Oceanic and Atmospheric…
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic…
