The James Webb Space Telescope will let scientists study small, rocky planets around distant stars in more detail than ever before. After decades of work, it could head into orbit later this year.
Intensive rehabilitative therapy that starts two to three months after a stroke may be key to helping the injured brain rewire, a new study suggests. That's later than covered by many insurance plans.
The visual problem is usually treated in kids by temporarily covering the other eye with a patch. But that doesn't always work. Research now shows crucial brain rewiring can happen in adulthood, too.
As the delta variant causes more vaccinated people to get "breakthrough infections," concerns are rising that even the vaccinated could develop long COVID symptoms in rare cases.
Tens of millions of Americans are forced to live with wildfire smoke now every year. New research shows that it's more invasive than previously thought, infiltrating homes, schools and offices.
With all the talk about COVID-19 vaccines and boosters, it's easy to forget that there's another respiratory virus poised to strike. We tackle questions about why a flu vaccine matters now.
ECMO, the highest level of mechanical life support, functions as a temporary heart and lungs for some of COVID-19's sickest patients. But the waitlist is too long for many patients who need it.
Using the COVID vaccine "off-label" — whether that's for booster shots or young children — may be tempting to some vaccine providers, but the CDC warns it could get them into trouble.
An experiment involving dog treats suggests our canine pals may understand the difference when a human withholds a treat by accident and when they do so on purpose. But don't press your luck.
After vaccination, antibody levels can help predict how much protection a COVID-19 shot offers, scientists are learning. The finding could speed up the development of future vaccines.
Starting treatment for addiction in the emergency room greatly improves the chances recovery will last, experts say. Cutting red tape, hiring advocates and Uber vouchers can all make a difference.
New research finds that sac-winged bat pups — a species of bat found in Central and South America — like to "babble" in ways that are remarkably similar to human babies.
If all goes to plan, Americans who got Pfizer or Moderna shots can get a third dose eight months after their last jab. Here's why health officials think you'll need one.
Mask mandates and other interventions can help stop a surge, even where vaccination rates are low, say scientists who've reviewed states' data. When the measures start and how long they last matters.
