Immune defense genes in bacteria and archaea can identify viral proteins, a study finds, revealing similarities between the immune systems of prokaryotic and eukaryotic organisms.
The scientific community bid farewell to researchers who furthered the fields of molecular biology, virology, sleep science, and immunology, among others.
Early reports that Omicron causes less-severe disease than Delta seem to be borne out, but it’s not yet clear to what extent that’s due to the variant itself versus the populations it’s infecting.
