Your genes could determine whether the coronavirus puts you in the hospital – and we're starting to unravel which ones matter

Researchers from Oregon Health and Science University found that variations in genes that code for parts of the cellular alarm system might play a role in how well people fight off COVID-19.

We found and tested 47 old drugs that might treat the coronavirus: Results show promising leads and a whole new way to fight COVID-19

Researchers at the University of California, San Francisco, identified nine existing drugs that show promise to treat COVID-19. The proteins they target haven't been tried before.
