Microfluidic systems redefined biology by providing platforms that handle small fluid volumes, catalyzing advancements in cellular and molecular studies.
Researchers turn to familiar model animals, along with some fresh strategies, to develop countermeasures against SARS-CoV-2 and investigate the biology of infection.
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.
