It has long been known that the Vikings arrived in the Americas sometime before Christopher Columbus. Now, a new article in the journal Nature concludes the exact year was 1021.
A family in Houston and a plumber in Maryland couldn't afford rent, which pushed them into crowded living quarters. During the COVID-19 pandemic, that common predicament has increased viral spread.
Should people who get a COVID booster get a different vaccine from their original shot? The results of a highly anticipated study suggest that in some cases the answer may be yes.
Research into the evolution of tardigrades has been severely hindered by a lack of fossils. This new discovery could offer researchers insight into how the creatures lived millions of years ago.
New research adds to growing concern over zero-calorie drinks. Consuming artificial sweeteners may confuse our body, leading to increased hunger and weight gain.
Scientists have created detailed maps of the brain area that controls movement in mice, monkeys and people. The maps could help explain human ailments like Alzheimer's and Lou Gehrig's disease.
Francis Collins has served longer than any other director of the National Institutes of Health since 1971. He tells NPR he did not anticipate the culture wars taking over scientific fact.
Mirya Holman, associate professor of political science at Tulane University, tells NPR about her research team's latest study on how socialization limits young girls' interest in politics.
The symptoms, such as headache, fatigue and cognitive dysfunction, persist or recur months after diagnosis, far more often than they do for the flu, researchers say.
For the first time, scientists are reporting they restored vision to people blinded by a rare genetic disorder by infusing the revolutionary gene-editing technique directly into cells inside the body.
In a first, doctors injected the gene-editing tool CRISPR directly into cells in patients' eyes. The experiment helped these vision-impaired patients see shapes and colors again.
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.
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.
