Does the knowledge of the extent of exposure to COVID-19 help to plan for the next wave? Why is the ICMR unlikely to launch a fourth study any time soon?
The story so far: Since the pandemic began in 2020, the Indian Council of Medical Research (ICMR) conducted three countrywide serosurveys to measure the spread of infection due to the SARS-CoV-2 virus. The third one (from December 17-January 8) showed that 21.5% of the population had been exposed to the virus. Up to May 23, India has been able to fully vaccinate only 3% of the population and only 10.9% had received one dose. There are indications that the ICMR is unlikely to immediately undertake a fourth national serology survey to estimate the extent of exposure to the coronavirus since January this year.

An avalanche in Chamoli: The global environmental crisis

Three seemingly unrelated natural disasters hit our world in the last few days.
On Feb 7, an avalanche struck Chamoli district, Uttarakhand. It destroyed two hydel power projects, leaving several dead and the entire area covered in slush and mud. Two Himalayan rivers, the Rishiganga and the Dhauliganga, flow down from the snow mountains.
There, a massive piece of glacial rock, over half-a-kilometre long according to the satellite images, detached itself from the mountain top.
Hurtling two kilometres, it crashed down with a massive explosion. Like a huge bomb-blast, it raised high clouds of mud, debris, and spray. The residents of that idyllic creek were blinded and dumbstruck by the deafening boom. Slurry stormed down to the plains — ice, stone, sand and water wreaking devastation upon anything that came in its way.

Morning Digest — February 20, 2021

The European Union (EU) envoys, who studied the ground situation for two days in J&K, on Friday have praised certain measures taken post August 5 in the Union Territory (UT) but called for “early organisation of the legislative Assembly elections,” which remains in a suspended animation since June 2018.
Amid severe criticism of frequent hike in fuel prices, questions on the issue by Opposition leaders at a meeting of the Parliamentary Standing Committee on Petroleum on Friday were shut down by Chairman and BJP leader Ramesh Bidhuri by shifting the blame on States for imposing additional taxes.
The Left-affiliated farmers organisation, which is part of the ongoing farm protests, argued that its proposal for legally guaranteed MSPs would not place the entire additional burden on the government budget, or ultimately, the taxpayer. Instead, the large corporates who make large profits from agribusiness must be forced to share their surplus with the primary producers, AIKS general secretary Hannan Mollah said.

This is a wonderful time to work on black holes: astrophysicist Parameswaran Ajith

The cosmic bodies have come out of their historical isolation to take centrestage in modern astrophysics, says the recipient of the inaugural young scientist award instituted by The World Academy of Sciences
Parameswaran Ajith, 40, a Bengaluru-based astrophysicist who specialises in the study of detecting gravitational waves, was chosen as the first recipient of The World Academy of Sciences-Chinese Academy of Sciences (TWAS-CAS) Young Scientist award for Frontier Science. He talks about his prize, the excitement of black holes, and about how he chose to become a scientist. Excerpts:
The award citation says you have “...pioneered a method to model the expected gravitational-wave signals from colliding binary black holes.” In layman’s terms, could you explain the principle of this method? Is it the only method for detecting wave signals or is it part of an algorithm of detection?

National Green Tribunal (NGT) Yearly Round-Up 2020

Scientific Disposal of Bio-Medical Waste arising out of COVID-19 treatment
The issue for consideration in this matter was the remedial action to address the gaps in compliance of the BMW Rules, 2016, as applicable to the disposal of bio-medical waste arising out of handling of COVID-19 disease, so as to ensure protection of environment and public health, in view of potential of such infectious waste adversely affecting public health, concerned workers and professionals etc.
Disposal of COVID-19 waste in general bins so as to be part of municipal waste or unscientific handling sewage and other liquid waste without safeguards can be hazardous. Need was felt to incorporate best practices apart from continued supervision and monitoring, compiling data in an online format, use of electronic /digital manifest system to track and log COVID-19 waste from all sources, preventing its accidental spillage, analyzing the data for strategic planning and the feedback by creating necessary software, to the extent viable.
