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.

A team of researchers is developed a test strip that can detect a toxin found in many species of deadly mushrooms.
As gyms open for business, new rules aim to limit the spread of COVID-19, including spacing equipment, regular cleanings and limiting attendance. But experts say it's still safer to exercise at home.
