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.

Doctors are using a new antigen test that is a faster method to spot people infected with the coronavirus. It's cheaper and simpler but may be less reliable.
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.

A type of discrimination is overlooked because it's rooted, not in hate, but in love. Our Hidden Brain team asks why good deeds, those we do for spouses or neighbors, can sometimes lead to injustice.
An experimental COVID-19 medicine that has been shown to shorten the time people with severe illness have to stay in the hospital finally has a price tag that's lower than some analysts expected.

A snake researcher always wondered how flying snakes propelled themselves. Then, someone told him he should work with the snakes in The Cube — a vast theater space with cameras everywhere.

It is no secret that the U.S. citizens are deeply divided along political lines. But a new study has found that Americans are not nearly as divided as they might think.
A coronavirus vaccine could become ineffective if the virus were to undergo certain genetic changes. But so far, so good: Scientists see no evidence that's happening.

Researchers around the world are tracking the mutations in the coronavirus as it reproduces and spreads to ensure changes in the virus do not affect the development of the vaccine.
Scientists have found that dolphins learn a neat trick to trap fish by watching their close associates do it. This means that dolphins aren't just motivated to learn from their mothers.
