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.
Many colleges and universities stopped requiring the SAT and ACT during Covid. Will they go back to testing in the future? Select: (a) Yes (b) No (c) Depends (d) Not enough information.
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
Population and animal studies suggested it could treat cancer, but the clinical trials were a bust. Here’s what happened and what potential may remain.
Some make nests inside seashells, others tote bubbles of air on their backs. The spiders that went back to water evolved lots of slick survival strategies.
One class of drugs has already found success in treating the painful, disorienting and common attacks. Excitement is building about a slew of additional drug targets.
Polygenic risk scores — a patient’s chance, based on tiny DNA variants, of developing cardiovascular disease, breast cancer and more — are coming to clinics. But there are kinks to iron out and accuracy remains an issue.
Australia’s iconic marsupial has been viewed as a food source, pest, mascot and, now, a conservation concern. Scientists are breaking down myths — using genetics, robots and citizen science — and finding new ways to protect the animals.
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.
As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? Key controls happen well before replication even starts.
To understand the origins of multicelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual past.
More than 70 years ago, mathematician Alan Turing proposed a mechanism that explained how patterns could emerge from bland uniformity. Scientists are still using his model — and adding new twists — to gain a deeper understanding of animal markings.
Picture your body: It’s a collection of cells carrying thousands of DNA errors accrued over a lifetime — many harmless, some bad, and at least a few that may be good for you.
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.
