Jon Hamilton is a correspondent for NPR's Science Desk. Currently he focuses on neuroscience and health risks.

In 2014, Hamilton went to Liberia as part of the NPR team that covered Ebola. The team received a Peabody Award for its coverage.

Following the 2011 earthquake and tsunami in Japan, Hamilton was part of NPR's team of science reporters and editors who went to Japan to cover the crisis at the Fukushima Dai-ichi nuclear power plant.

Hamilton contributed several pieces to the Science Desk series "The Human Edge," which looked at what makes people the most versatile and powerful species on Earth. His reporting explained how humans use stories, how the highly evolved human brain is made from primitive parts, and what autism reveals about humans' social brains.

In 2009, Hamilton received the Michael E. DeBakey Journalism Award for his piece on the neuroscience behind treating autism.

Before joining NPR in 1998, Hamilton was a media fellow with the Henry J. Kaiser Family Foundation studying health policy issues. He reported on states that have improved their Medicaid programs for the poor by enrolling beneficiaries in private HMOs.

From 1995-1997, Hamilton wrote on health and medical topics as a freelance writer, after having been a medical reporter for both The Commercial Appeal and Physician's Weekly.

Hamilton graduated with honors from Oberlin College in Ohio with a Bachelor of Arts in English. As a student, he was the editor of the Oberlin Review student newspaper. He earned his master's degree in journalism from Columbia University, where he graduated with honors. During his time at Columbia, Hamilton was awarded the Baker Prize for magazine writing and earned a Sherwood traveling fellowship.

MARY LOUISE KELLY, HOST:

Math is a field that is dominated by men, yet young boys and girls seem to be no different in math ability. NPR's Jon Hamilton reports on a new study comparing the brain activity of boys and girls doing basic math.

There's new evidence that girls start out with the same math abilities as boys.

A study of 104 children from ages 3 to 10 found similar patterns of brain activity in boys and girls as they engaged in basic math tasks, researchers reported Friday in the journal Science of Learning.

"They are indistinguishable," says Jessica Cantlon, an author of the study and professor of developmental neuroscience at Carnegie Mellon University.

The brain waves generated during deep sleep appear to trigger a cleaning system in the brain that protects it against Alzheimer's and other neurodegenerative diseases.

Electrical signals known as slow waves appear just before a pulse of fluid washes through the brain, presumably removing toxins associated with Alzheimer's, researchers reported Thursday in the journal Science.

When Sepiedeh Keshavarzi was getting her medical degree in Tehran, she often read research papers by prominent scientists in the U.S.

"It was my dream at some point when I was much younger to do research in the States," she says.

Not anymore.

Brain scientists are offering a new reason to control blood sugar levels: It might help lower your risk of developing Alzheimer's disease.

"There's many reasons to get [blood sugar] under control," says David Holtzman, chairman of neurology at Washington University in St. Louis. "But this is certainly one."

Educators refer to teens like Alex as "twice exceptional."

"I have a large degree of skill in almost every subject of learning," says Alex, who is 16. "But I also have autistic spectrum disorder."

For Alex, this dual identity has meant both opportunity and frustration.

He has skipped two grades so far, and began taking college math courses last year, when he was still 15. But when he was younger, Alex's underdeveloped social skills caused him a lot of grief.

"I was constantly getting into fights and normally losing them," he says.

The link between vaping and severe lung problems is getting a lot of attention.

But scientists say they're also worried about vaping's effect on teenage brains.

"Unfortunately, the brain problems and challenges may be things that we see later on down the road," says Nii Addy, associate professor of psychiatry and cellular and molecular physiology at Yale School of Medicine.

Too much physical exertion appears to make the brain tired.

That's the conclusion of a study of triathletes published Thursday in the journal Current Biology.

Researchers found that after several weeks of overtraining, athletes became more likely to choose immediate gratification over long-term rewards. At the same time, brain scans showed the athletes had decreased activity in an area of the brain involved in decision-making.

Researchers are beginning to understand why certain brain cancers are so hard to stop.

Three studies published Wednesday in the journal Nature found that these deadly tumors integrate themselves into the brain's electrical network and then hijack signals from healthy nerve cells to fuel their own growth.

The depression drug esketamine, marketed as Spravato, appears to offer quick relief to people who are actively considering suicide.

Esketamine, a chemical cousin of the anesthetic and party drug ketamine, reduced depression symptoms within hours in two large studies of suicidal patients, the drug's maker announced Monday.
