As lawmakers push for billions of dollars to fund the nation’s efforts to track coronavirus variants, the Biden administration announced on Wednesday a new effort to ramp up this work, pledging nearly $200 million to better identify the emerging threats.

As Americans anxiously watch variants first identified in the United Kingdom and South Africa spread in the United States, scientists are finding a number of new variants that originated here. More concerning, many of these variants seem to be evolving in the same direction — potentially becoming contagious threats of their own.

In a study posted on Sunday, a team of researchers reported seven growing lineages of the novel coronavirus, spotted in states across the country. All of them have evolved a mutation in the same genetic letter.

“There’s clearly something going on with this mutation,” said Jeremy Kamil, a virologist at Louisiana State University Health Sciences Center Shreveport and a co-author of the new study. Continue reading “7 Virus Variants Found in U.S. Carrying the Same Mutation” →

British government scientists are increasingly finding the coronavirus variant first detected in Britain to be linked to a higher risk of death than other versions of the virus, a devastating trend that highlights the serious risks and considerable uncertainties of this new phase of the pandemic.

The scientists said last month that there was a “realistic possibility” that the variant was not only more contagious than others, but also more lethal. Now, they say in a new document that it is “likely” that the variant is linked to an increased risk of hospitalization and death.

In recent years, scientists have figured out how to grow blobs of hundreds of thousands of live human neurons that look — and act — something like a brain.

These so-called brain organoids have been used to study how brains develop into layers, how they begin to spontaneously make electrical waves and even how that development might change in zero gravity. Now researchers are using these pea-size clusters to explore our evolutionary past.

In a study published on Thursday, a team of scientists describe how a gene likely carried by Neanderthals and our other ancient cousins triggered striking changes in the anatomy and function of brain organoids.
