Covishield generates 93% protection against COVID-19
According to a study done by Armed Forces Medical College (AFMC), Covishield vaccine offers 93% protec- tion against COVID-19 and reduces the mortality rate by 98%. The study is based on a research conducted on 15 lakh doctors and frontline work-
Covishield is one of the vaccines being administered in India
ers during the second wave in India. Though no vaccine guarantees perma- nent protection against infection, the severity of the disease is mitigated and nearly eliminated if it recurs.
IIT researchers make breakthrough in pricing ‘carbon risk’
A new mathematical analysis con- ducted by researchers from the Indian Institute of Technology, Guwahati (IIT-G) and IIM Bangalore has established a relationship between the carbon footprint of companies and
the potential risks of investing in these firms. The researchers did an extensive data analysis of over 200 of the larg- est listed companies in the American market and the findings have been published in arXiv, a curated research- sharing platform maintained by a team at the US-based Cornell University.
Cyber security solutions for anti- drone technologies
The presence of cutting-edge technol- ogy in cyber security is accompanied by an increasing need to protect digital assets and deploy solutions for the common public as well as government and industry. Indian Institute of Tech- nology, Kanpur (IIT-K) has launched the first technology innovation hub to find cyber security solutions for anti-
drone technologies, intrusion detection system, block-chain and cyber physical system. As many as 13 start-ups and 25 research and development principal investigators were selected.
New shark species from Indian
Ocean discovered
A new weird looking shark species from Indian Ocean has been discov- ered. It belongs to the Apristurus spongiceps subgroup and is the second known species occurring in the west- ern Indian Ocean. The search was conducted along the Southwest Indian Ridge, which is an underwater moun- tain ridge separating the tectonic plates of Somali in the north to Antarctica
in the south. The fish was found by researchers while they were examining the seamounts situated in the south of Madagascar, in the Indian Ocean, in 2012 and 2014.
Astronomers spot unique
Gamma-ray burst
A group of astronomers, including a few Indians, has detected the shortest Gamma-ray burst (GRB) caused by the death of a massive star. This Gamma- ray is a very short, powerful burst of high-radiation that lasted for about a second and had been racing towards the Earth for nearly half the present age of the universe.

Drug for pan-coronavirus
treatment identified
Scientists have identified the most highly conserved drug-binding pockets in viral proteins from COVID-19 pa- tient samples and from other corona- viruses, revealing the most promising targets for pan-coronavirus drugs.
The researchers from the University of Toronto in Canada noted that safe and effective vaccines offer hope for an end
to the COVID-19 pandemic. However, the possible emergence of vaccine- resistant SARS-CoV-2 variants, as well as novel coronaviruses, make finding treatments that work against all coronaviruses as important as ever, they said.
The Red Planet has molten core
just like the Earth
A Mars quake is unveiling the red planet’s subsurface for the first time, revealing an unexpectedly thin crust and a boiling molten core under the icy surface. Scientists, in a series of stud- ies, announced that the Martian crust
The seismometer of NASA’s InSight lander collects data on Mars
is within the thickness range of the Earth’s crust. Between the crust and the core, the Martian mantle is about half as thick as the Earth’s. The Mar- tian core is also larger than scientists expected while being smaller than the core of our own.
Ancient shark teeth recorded Earth’s climate history
Some 50 million years ago, the earth began shifting from a greenhouse climate that was warmer than today toward icehouse conditions. There is geologic evidence that both the Drake Passage, which is the water between South America and the Antarctic Peninsula, and the Tasman Gateway, between Australia and East Antarc- tica, widened and deepened during this time as the Earth’s tectonic plates moved. By studying the chemistry pre- served in these shark teeth, evidence has been found of when the Drake Pas- sage opened, which allowed the waters of the Pacific and Atlantic oceans to mix, and what the water felt like at
the time.
