If confirmed, Eric Lander would be the first biologist to run the US Workplace of Science and Expertise Coverage.
Biden names high geneticist as science adviser
US president-elect Joe Biden has chosen the decorated geneticist Eric Lander as his presidential science adviser and the director of the Workplace of Science and Expertise Coverage (OSTP). If Lander’s appointment is confirmed by the US Senate, he’ll function a member of Biden’s cupboard — a primary for this place.
Lander was a key chief of the Human Genome Undertaking — the race to sequence the human genome, which led to 2003 — and is the president and founding director of the Broad Institute of MIT and Harvard in Cambridge, Massachusetts. He would be the first biologist to run the OSTP.
Biden has additionally introduced the appointment of various different revered scientists to key positions in his administration. Alondra Nelson, nominated to be deputy director for science and society on the OSTP, is a social scientist on the Institute for Superior Examine in Princeton, New Jersey, who research genetics, race and different societal points. Nobel laureate Frances Arnold, a bioengineer on the California Institute of Expertise in Pasadena, and Maria Zuber, a geophysicist at MIT, will co-chair the President’s Council of Advisors on Science and Expertise, an elite panel that advises the president.

COVID reinfections uncommon however harmful
Most individuals who catch and get well from COVID-19 are more likely to be immune for several months afterwards, a research of greater than 20,000 health-care employees in the UK has discovered.
The research — known as SARS-CoV-2 Immunity and Reinfection Analysis (SIREN) — concluded that immune responses from previous an infection cut back the chance of catching the virus once more by 83% for at the very least 5 months. It was revealed on-line on 15 January (V. Hall et al. Preprint at medRxiv https://doi.org/fq3j; 2021).
Each two to 4 weeks, SIREN contributors underwent blood checks for SARS-CoV-2 antibodies, in addition to PCR checks to detect the virus itself. The outcomes counsel that repeat infections are uncommon — they occurred in fewer than 1% of about 6,600 contributors who had already had COVID-19. However researchers additionally discovered that individuals who grow to be reinfected can carry excessive ranges of the virus of their nostril and throat, even when they don’t present signs. Such viral hundreds have been related to a excessive danger of transmitting the virus to others.
“Reinfection is fairly uncommon, in order that’s excellent news,” says immunologist John Wherry on the College of Pennsylvania in Philadelphia. “However you’re not free to run round with no masks.”

Vaccine makers rush to check photographs towards new variant
Vaccine makers in India and China are investigating whether recently approved COVID-19 vaccines are effective towards a fast-spreading variant of the virus SARS‑CoV-2 now circulating around the globe.
Scientists on the Indian Council of Medical Analysis in New Delhi and Bharat Biotech in Hyderabad, are testing whether or not their vaccine, Covaxin, is efficient at blocking a variant called B.1.1.7, which emerged in the United Kingdom. The shot is one in all a number of first-rollout vaccines to make use of an inactivated complete virus to elicit an immune response.
Scientists in China have additionally examined whether or not a particular mutation in B.1.1.7’s spike protein might compromise a vaccine developed by Sinopharm, one in all three inactivated-SARS-CoV-2 photographs being rolled out in China.
Some researchers have prompt that whole-virus vaccines might carry out higher towards new variants than can photographs that depend on the spike protein to elicit an immune response. If a variant escapes a response directed towards the spike protein, it would nonetheless produce other susceptible areas {that a} whole-virus vaccine might assault, says Srinath Reddy, head of the Public Well being Basis of India in New Delhi. However “nothing has been demonstrated as but,” he says.
