science news 12.11.2020

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary in italics in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without italics if I have any.

Largest set of mammalian genomes reveals species at risk of extinction
An international team of researchers with the Zoonomia Project has released the whole genomes of more than 80 percent of all mammalian families, spanning almost 110 million years of evolution. The dataset, published in Nature, includes genomes from more than 120 species that were not previously sequenced, capturing mammalian diversity at an unprecedented scale. Zoonomia data have already helped researchers in another recent study to assess the risk of infection with SARS-CoV-2 across many species.
