IIT Kharagpur researchers flag how weather changes affect people

A new study by a team of researchers of IIT Kharagpur has warned that extreme weather events are not only becoming more frequent and intense but also affecting people very differently depending on where they live and how old they are. An IIT Kharagpur spokesperson said on Wednesday that by combining detailed climate projections with demographic data, the study compared the recent past (19912020) with the near future (20212050) under various warming and population growth scenarios. The research team, led by Prof Rajib Maity of Civil Engineering department, looked at how heat waves or cold waves can overlap with heavy rain or dry extremes. Its findings highlight stark insights as heat-related extremes concurrent with floods or droughts are projected to rise sharply worldwide, and Asia and Africa are set to be the hardest hit, with children and working-age adults facing the greatest risk. The study further flagged that sub-Saharan Africa will experience the highest youth exposure to .

Sushant Singh Rajput case: CBI seeks transfer of hearing on closure report

A court here on Tuesday permitted the Central Bureau of Investigation (CBI) to seek transfer of the hearing in the closure report submitted by the agency in actor Sushant Singh Rajput death case to a designated court. The central probe agency had last month filed its closure report in the death case before the Bandra metropolitan magistrate's court. The actor was found hanging in his apartment in Mumbai's Bandra area on June 14, 2020 at the age of 34. In the conclusive medico-legal opinion to the CBI, forensic specialists at the All India Institute of Medical Sciences (AIIMS) had dismissed the claims of "poisoning and strangling" made in the case, the CBI had said in its report. On Tuesday, the agency informed magistrate K C Rajput that it would move an application before the chief judicial magistrate to transfer hearing in the case to the Esplanade magistrate's court, which is designated to hear CBI cases. Magistrate Rajput permitted the same and said the agency is directed to ..

Covid variants still transmissible between species, reveals study

The SARS-CoV-2 virus is still highly transmissible between mammals, according to a study based on computer simulations. Researchers at Rochester Institute of Technology (RIT), US, found that coronaviruses use their spike proteins -- which help them to infect cells -- to attach themselves to the host cells in both bats and humans in much the same way. The findings, published in the journal Royal Society Open Science, show how the viral spike proteins in several SARS-CoV-2 variants interact with the host cell receptors known as ACE2 in both humans and various bats of genus Rhinolophus. "We were hoping to see really cool adaptive evolution happening as the virus got more used to humans and less used to bats, but we actually saw that there wasn't a whole lot of change," said Associate Professor Gregory Babbitt from RIT. "Because this binding site has not evolved very much, there's really not much stopping it from transmitting from humans to bats," Babbit said in a statement. Scientist
