Johnson & Johnson's potential coronavirus vaccine prevented severe illness in a small group of Syrian golden hamsters, the company announced Thursday.

J&J said the vaccine elicited neutralizing antibodies, which researchers believe are necessary to build immunity to the virus, in hamsters who got the vaccine. Vaccinated hamsters also appeared to lose less weight than unvaccinated hamsters and didn't experience severe clinical disease, like pneumonia and mortality. The results were published Thursday in the medical journal Nature Medicine. "This pre-clinical study further validates our confidence in our SARS-CoV-2 vaccine candidate...

As if the novel coronavirus has not already wrought devastation aplenty on the world, physicians and researchers are seeing signs it is doing deep damage to people’s sleep. “Coronasomnia,” as some experts now call it, could prove to have profound public-health ramifications — creating a massive new population of chronic insomniacs grappling with declines in productivity, shorter fuses and increased risks of hypertension, depression and other health problems. It’s easy to see why people can’t sleep, expe...
