Brain organoids grown in the lab look a lot like developing human brains. But a new study finds some important differences that could affect how scientists use them.

Forty mice spent more than a month in orbit to test two approaches to strengthening muscle and bone in microgravity conditions. The results could help people with muscle and bone diseases.

Black and Hispanic people often don't volunteer for studies of Alzheimer's disease, despite their risks for developing it. Researchers are working to make studies more inclusive, but it's not easy.

A leukemia drug seemed to help patients with Parkinson's disease. But critics say the results are equivocal and could raise false hopes.

One medical student was addicted to opioids. Another relied on them to control disabling pain. Both think their experiences will help them be better doctors when it comes to prescribing opioids.

Syllables are the building blocks of spoken language. And now a study of brain activity hints at how we extract them from a stream of speech.

A former vaper has a warning for others. And, scientists work to understand how nicotine affects the teenage brain. (This segment initially aired on Oct. 10, 2019 on Morning Edition.)

Former President Jimmy Carter, 95, was admitted to Emory University Hospital on Monday evening for the procedure. He was accompanied by his wife, Rosalynn.

Research shows that when boys and girls as old as 10 do math, their patterns of brain activity are indistinguishable. The finding is the latest challenge to the idea that math is harder for girls.

Brain scans of 104 boys and girls doing basic math tasks found no gender differences. The finding adds to the evidence that boys and girls start out with equal ability in math.

A study of 11 sleeping brains sheds some light on the mysterious link between sleep problems and Alzheimer's disease. The flow of cerebrospinal fluid through the brain appears to be the key.

Scientists from nations including Iran, Mexico, and India were refused visas to attend this year's Society for Neuroscience meeting in Chicago. Some researchers got stand-ins to present their work.

Diabetes can double a person's chances of developing Alzheimer's. Now researchers are beginning to understand the role of brain metabolism in the development of the disease.

People with diabetes are more likely to develop Alzheimer's disease. Researchers say they are beginning to understand why, and the answer has to do with the way the brain uses sugar.

A center at the University of Iowa is making sure that its programs for gifted teens include those with autism spectrum disorders.

Research on young mice and rats shows how nicotine hijacks brain systems involved in learning, memory, impulse control and addiction.

Research finds that triathletes who train too hard can impair a brain area involved in achieving goals such as winning a race. Fatigued athletes choose immediate gratification over long-term rewards.

Researchers say certain brain cancers tap electrical signals from healthy cells to fuel their growth. The finding could lead to treatments for deadly tumors like the one that killed Sen. John McCain.

Spravato, a nasal spray of the anesthetic ketamine, has been shown to help people with major depression. Now studies show it can relieve depressive symptoms in people actively considering suicide.

Researchers say clusters of human brain cells grown in the lab can spontaneously generate electrical patterns similar to the brain waves of a 6-month-old fetus.
