Even as the #Omicron variant of the coronavirus continues to infect people in large numbers across the world, news about the emergence of another highly-mutated variant spread rapidly, raising fears of yet another wave of infections. #IHU
This variant, B.1.640, has been found mostly in France so far, although it has also been detected in several other countries. The variant was reported to have 46 mutations, including some in the spike protein.
The sudden discussion around it was triggered by the circulation of a week-old study by researchers from Méditerranée Infection in Marseille, part of France’s Instituts hospitalo-universitaires (#IHU, or University Hospital Institutes).
The one that the French researchers found among people in November has now been classified as a sub-lineage B.1.640.2.

Is #IHU spreading rapidly?
According to outbreak.info, a website that tracks the prevalence of different variants in genome sequencing databases,at least 400 infections with the B.1.640 variant have so far been identified. It has been detected in at least 19 countries.
While the large number of significant mutations in this variant has attracted the interest of researchers, and raised concerns among the public. Is B.1.640 spreading at an unnerving rate? indianexpress.com/article/explai…
With every infection come new opportunities for the virus to mutate. But the legacy of past epidemics, as well as some basic biological principles, provides clues to where we could be headed. indianexpress.com/article/world/…

This past December gave us a self-aware and fleet-footed film #MinnalMurali, as well as a superficial and unoriginal new series #Decoupled. Here is @RajaSen's verdict about the month gone by.

🧵 THREAD Image
It is hard not to be taken in by #MinnalMurali, set in a tiny village with immense character, featuring a roguish and gullible hero, played by the preposterously charming Tovino Thomas, who said it fulfilled his one childhood wish – to become a superhero. indianexpress.com/article/entert…
#MinnalMurali is a joyous, self-aware and fleet-footed entertainer, which also questions the absolute nature of good vs evil the genre is founded on. Even Mahatma Gandhi would cheer for that. The actor behind the supervillain can attest to that. indianexpress.com/article/entert…

More than 40 lakh teenagers in the 15-18 age group received their first dose of #Covid19 vaccines on Monday. Some concerns were raised about ‘expired’ #Covaxin being administered to this younger group, leading to the Health Ministry issuing a clarification.
The Ministry described these claims as “false and misleading” and said these were based on “incomplete information”. It pointed out that the shelf life of #Covaxin, the only vaccine being given to the people below 18 years of age, had been extended: indianexpress.com/article/india/…
The Health Ministry said the shelf life of #vaccines is extended by the national regulator, Central Drugs Standard Control Organisation, or CDSCO, based on a comprehensive analysis and examination of stability study data furnished by the vaccine manufacturers.

The #Cryptocurrency and Regulation of Official Digital Currency Bill, 2021, listed for introduction in Parliament’s Winter Session starting Nov 29, seeks to “create a facilitative framework for the creation of the official digital currency to be issued by the RBI”.
The Bill “seeks to prohibit all private cryptocurrencies in India, however, it allows for certain exceptions to promote the underlying technology of #cryptocurrency and its uses”. indianexpress.com/article/techno…
#ExpressEditorial | To be sure, there are legitimate concerns over #cryptocurrencies. But an outright ban, even though there are questions over its enforceability, would not be the prudent way forward: indianexpress.com/article/techno…
