Study shows how variations in SARS-CoV-2 host gene expression can be linked to variations in COVID-19 susceptibility and symptom severity. People have different susceptibilities to SARS-CoV-2, the virus behind the COVID-19 pandemic, and develop varying degrees of fever, fatigue, and breathing problems — common symptoms of the illness. What might explain this variation?

Scientists at the University of California, Riverside, and University of Southern California may have an answer to this mystery.

In a paper published in Informatics in Medicine Unlocked, the researchers show for the first time that the observed COVID-19 vari...

Repurposed Drugs may help scientists Fight the New Coronavirus


M protease (model shown) is a key enzyme for the new corona­virus’ survival and may be an Achilles’ heel. Drugs (blue) might be able to nestle into the enzyme and stop viral replication. DAVID S. GOODSELL/RCSB PROTEIN DATA BANK

Work on similar viruses is giving researchers clues to develop drugs against the disease. As the new coronavirus makes its way around the world, doctors and researchers are searching for drugs to treat the ill and stop the spread of the disease, which has already killed more than 3,800 people since its introduction in Wuhan, China, in December.

The culprit virus is in the same family as the coronaviruses that caused two other outbreaks, severe acute respiratory syndrome and Middle East respiratory syndrome...
