SARS-CoV-2 Could Use Nanotubes to Infect the Brain
Stressed cells can form hollow actin bridges to neighbors to get help, but the virus may hijack these tiny tunnels for its own purposes, a study suggests.

Possible Case of Deer-To-Human SARS-CoV-2 Transmission
Catherine Offord | Mar 3, 2022
Canadian researchers identify a highly mutated variant of the virus in white-tailed deer and link it to a human COVID-19 case in the region—though they emphasize that the infection risk to people is low.

Does Science Support Lifting School Mask Mandates?
Rachael Moeller Gorman | Feb 28, 2022
The CDC has given the OK to lift indoor mask mandates in much of the US, and a growing number of states no longer require face coverings in schools. But most experts agree that masks slow school spread of SARS-CoV-2, and whether now is the right time to allow teachers and students to unmask is a matter of debate.
