An experiment that induced imaginary sounds in both people and mice could help explain how brain disorders like schizophrenia cause hallucinations.

Humans evolved to be nice — at least sometimes. The trait has helped us succeed as a species. But how did it happen? A look at some peace-loving apes in Democratic Republic of the Congo offers clues.

Surveys show that support for COVID-19 vaccines is rising among Black and Latinx populations, now that tens of millions of Americans have safely received the shots.

Research on bonobos, one of our closest and gentlest relatives, may show how humans evolved to share and cooperate on a massive scale.

Friday marked the busiest day for the nation's airports since COVID-19 put the brakes on air travel almost a year ago. But the number of travelers remains far below 2019 levels.

The two countries joined a number of other European nations that have temporarily suspended the shot after several people reportedly developed blood clots after receiving it.

Nonwhite Americans looking for care for a loved one are much more likely than whites to encounter discrimination, language barriers, and providers who lack cultural competence, a new report finds.

Lab-grown brainlike organoids altered with an ancient gene began to look and behave differently. The experiments help show how the human brain has evolved.

A brain organoid grown with Neanderthal DNA reveals how evolution shaped the brains of modern humans and adds to evidence that brain differences helped us survive while our human cousins went extinct.

Two studies find that tailoring brain stimulation to a particular patient helps in treating depression and obsessive-compulsive behaviors.

Two new studies show the potential of personalized brain stimulation to treat psychiatric disorders. The approach delivers pulses of electric or magnetic energy to certain areas in the brain.

Severe cases of COVID-19 can injure the brain in ways that affect memory, thinking and mood for months after the infection is gone, new research hints. It may even raise the risk of Alzheimer's.

COVID-19 can damage the brain, causing long-term problems with thinking and memory. New research suggests the damage comes from the immune system's reaction to the coronavirus, not the virus itself.

A synthetic version of the psychedelic drug ibogaine appears to relieve depression and addiction without producing hallucinations or other dangerous side effects — at least in rodents.

Government scientists estimate that the true number of coronavirus infections is eight times the reported number of 12.5 million, meaning "most of the country remains at risk," the team reports.

A newly approved drug can extend the lives of children with progeria, a rare disorder that causes rapid aging. The drug is the result of one family's effort to help a child with the fatal condition.

The Food and Drug Administration has approved a treatment for progeria, a genetic disorder that causes children to age rapidly. Zokinvy is the first drug approved by the agency for the disorder.

People who get more deep sleep appear less likely to develop Alzheimer's. That may be because this phase of sleep allows the brain to clear out waste products.

There's growing evidence that a lack of deep sleep increases the risk of Alzheimer's disease. Scientists say that's because during deep sleep, the brain removes toxins associated with Alzheimer's.

A Food and Drug Administration advisory committee voted that studies of the drug aducanumab for Alzheimer's treatment don't show it's effective.
