It’s easy to get, but difficult to study or treat. Scientists are making progress against the virus thanks to an infusion of cash and a new way of culturing it in the lab.
Differences between the immune systems of males and females — in particular, ones involving cells called microglia — might help explain why the risk for conditions such as autism and Alzheimer’s varies between the sexes
Researchers helped mice stay mighty with an experiment to counter the effects of microgravity. The gene treatment might also enhance muscle and bone health on Earth — and in humans.
Antibodies should indicate if someone has had an infection in the past. But the promise of “immunity testing” is plagued by uncertainty about how the immune system responds to the coronavirus, as well as concerns about the tests’ accuracy.
While studies in mice and people can be slow, researchers are making fast progress testing medications in miniature airways and guts made of human cells
OPINION: Many Americans say they won’t take a vaccine. I am not one of <br xmlns="http://pub2web.metastore.ingenta.com/ns/"/>them — and I have the shots to prove it.
Antibiotics abound, but virus-fighting drugs are harder to come by, and Covid-19 amply shows how much we need them. Fortunately, scientists are getting better at making and finding them.
Out-of-control clotting can endanger some patients even after the virus has gone. Clinicians and researchers are trying to understand why it happens and how best to manage the problem.
The ‘tripledemic’ unfolding this winter is one of several odd trends among respiratory virus infections these last years. Viruses, it turns out, can block one another and take turns to dominate.
Some serious cases of Covid-19 are linked with the immune system’s attack on the body it’s trying to protect
