NASA and SpaceX are welcoming home two astronauts who splashed down safely in the Gulf of Mexico after several months on the International Space Station.
Scientists are now checking to see if purified blood serum from people who have recovered from COVID-19 might be more than a useful treatment. Perhaps it's a way to prevent disease in someone else.
With the coronavirus spreading out of control in many parts of the U.S., some experts say the strategy of testing and tracing can't contain the pandemic until lockdowns bring case numbers down.
Face coverings are key to stopping spread of the coronavirus, but also slow communication, especially for people who don't hear well. Volunteers and companies suggest some transparent alternatives.
Gene therapy has helped a 9-year-old boy regain enough muscle strength to run. If successful in others, the treatment could change the lives of thousands of children with Duchenne muscular dystrophy.
Two new human studies back earlier hints that vaccines designed to prevent respiratory infections might also provide some protection against Alzheimer's disease.
A growing number of researchers think until there's an effective vaccine, the coronavirus will simply persist in the population, causing illness indefinitely. Better to squelch the spread instead.
Recent studies have raised fears that immunity to the coronavirus might be fleeting, thus making potential vaccines ineffective. The reality of the science is more complex — and more reassuring.
A single test that can give false reassurance sounds bad. But a $10 test for the coronavirus, if repeated daily, would discover real infections, say proponents of such tests as screening tools.
Researchers believe gene therapy is poised to change the lives of thousands with the fatal genetic disorder Duchenne muscular dystrophy — thanks to over 40 years of scientist Jude Samulski's work.
The first gene therapy for hemophilia could be approved by the FDA within six months, according to the drugmaker, raising hopes among families. But the drug's price could be $3 million per patient.
Preliminary evidence suggests the coronavirus can pass through the placenta, and pregnancy slightly raises a woman's risk of a severe case of COVID-19. Medical experts urge calm and common sense.
NASA is sending a 6-wheeled rover to Mars to look for signs of microbial life stored in the rocks at Jezero crater. The rover is also the first step in returning samples of Martian rock to Earth
Though anxiety has increased in the U.S. in recent months, a drastic spike in loneliness that psychologists expected hasn't emerged. People seem to be finding new ways to connect, researchers say.
Scientists have discovered an enzyme that is elevated in people and mice who exercise a lot. They hope the discovery could lead to medicine that would have some of the benefits of exercise.
Scientists have come up with a new formula to calculate a dog's age in human years — and it is much more complicated than multiplying its real age by seven.
Experiments in people have long shown that the presence of indifferent bystanders hurts the chances that someone will help a stranger in an emergency. Rats, it turns out, behave the same way.
Structures inside healthy brain cells nimbly move from one state to the next to perform different functions. But in certain degenerative brain diseases, scientists now think, that process gets stuck.
Among the young, the numbers shot up: 9% of adults 18-29 have moved due to the coronavirus. Some people moved to avoid catching the virus, while others were forced by the closing of college campuses.
J. Paul Taylor has found that some brain diseases, like Alzheimer's and ALS, are linked to a basic process inside brain cells. Scientists hope drugs that tweak the process can treat illnesses.
Dentists spend their careers eye to eye with infectious patients, their hands inside gaping mouths, and have a vested interest in making sure everyone stays safe. Here's how they do it.
It's not that young adults aren't worried about the pandemic, psychologists say, but they are at far greater risk of dying by suicide. Finding ways beyond screens to foster social bonds is crucial.
