Progress against malaria has stalled. Now a team is trying a new tactic.

Research suggests the more of your childhood that is spent surrounded by green spaces, the lower your risk of developing mental illness in adulthood, whether in the city or the country.

In our recent story on the evolutionary benefits of grandmothers, we asked our audience: How did you and your grandma help your family survive and thrive? Readers share their stories.

Humans are evolutionary oddballs for living long past our reproductive prime. New research explains how grandmothers might be the reason why.

Some antidepressants inhibit a liver enzyme that converts common opioids into their active form. The interaction may reduce the effectiveness of certain opioids for people taking both medicines.

In the search for what triggers sleep, researchers stumbled upon a link between sleep and the immune system. A single fly gene gets turned on in sick flies, inducing sleep and an immune response.

New findings about the health effects of e-cigarettes add to a small but growing body of research that undercuts the widely presumed safety of the alternative to conventional cigarettes.

Muscle cells may retain nuclei that helped them grow strong, even after muscles shrink from lack of use. This provocative contentious idea could have implications for public health and sports.

Researchers have pinpointed the neurons that give pain its unpleasant edge. By turning these neurons off in mice, the scientists relieved the unpleasantness of pain without numbing sensation.

An insect-killing bacteria that lives inside a parasitic worm might hold the key to developing a powerful new repellent.

A new report documents how Coke penetrated the government and influenced efforts to bring down the growing obesity rate — but not by cutting back on calories.
