The topographical features of DNA in the body may dictate where and when cancer-causing mutations appear in its code.

Scientists say they've identified a potential living relative of the ancient microbe that gave rise to the "powerhouse of the cell."

Researchers have confirmed the existence of an odd type of brain cell that other neuroscientists once thought might be only a technical quirk or error.

In animal studies, the weight-loss drug Ozempic has shown promise as an anti-addiction medicine. Whether it could work the same in humans remains to be seen.

New York City's normally good air quality rating recently plummeted to the worst of any major city in the world, as wildfire smoke drifted over the city from Canada.

Sleep apnea and a lack of deep sleep may be linked to abnormalities in the brain's white matter.

Researchers identified patterns of brain wiring that seem to be linked to a person's risk of having multiple psychiatric disorders.

Hormonal contraceptives slightly raise users' risk of breast cancer, regardless of whether they're combination or progestogen-only.

A study suggests that just one night of sleep deprivation may be linked to structural changes in the brain, similar to those seen in aging.

An experimental study suggests that diesel fumes might disrupt the brain's typical pattern of activity.

Cancer cells can lie dormant for years and then suddenly start spreading.

COVID-19 may increase the risk of giving birth prematurely, according to the largest study to date on this link.

Scientists have created key parts of synthetic brain cells that can hold cellular "memories" for milliseconds. The achievement could one day lead to computers that work like the human brain.
