Public health messages should be loud and clear, so that everyone listens and stays safe. But that’s easier said than done — especially with a case as complex as Covid-19.
Bats cope with myriad viruses, including the one causing Covid-19, with few ill effects. Scientists are probing their immune systems to fathom how they do it. The answers might help infected people, too.
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
Drug treatments and vaccines for Covid-19 are needed fast. But developing them in mid-outbreak is logistically hard and ethically tricky. A veteran vaccine researcher explains.
From mask wearing to physical distancing, individuals wield a lot of power in how the coronavirus outbreak plays out. Behavioral experts reveal what might be prompting people to act — or not.
It began with an email from Wuhan, a Maine laboratory and mouse sperm from Iowa. Now that lab is on the verge of supplying a much-needed animal for SARS-CoV-2 research.
Reports of patients with neurological symptoms have emerged during the pandemic. Scientists don’t yet know whether these are a direct effect of the virus or part of the body’s response to infection.
Studies on astronauts and Antarctic crews reveal how extreme confinement affects small groups. Scientists are racing to figure out isolation’s impact on the rest of us.
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.
We know pathogens from other species can endanger us. Scientists are better equipped than ever to do something about it, but political buy-in is crucial.
The body’s defenses lose flexibility and diversity over time, and protective responses to vaccines weaken as well. Scientists are working on ways to boost seniors’ protections against influenza, the novel coronavirus and other pathogens.
Social media posts and online searches may offer vital clues about the spread of influenza — and now Covid-19. But they also risk errors and threaten privacy.
The eye-catching spikes sticking out from the surface of SARS-CoV-2 may inspire new ways to prevent or treat Covid-19 infections
