Jon Hamilton

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

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 degree 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.

A major study is challenging the widely held view that adult human brains make new neurons.

The study of brain samples from 59 people of various ages found no immature neurons in anyone older than 13, scientists report online Wednesday in the journal Nature.

When the body gets dehydrated, the brain tells us to start chugging fluids. But what tells us when to stop?

The answer appears to be a brain circuit that acts like a water meter, constantly measuring how much fluid we are taking in, a team reports Wednesday in the journal Nature.

Beer has fueled a lot of bad ideas. But on a Friday afternoon in 2007, it helped two Alzheimer's researchers come up with a really a good one.

A little electrical brain stimulation can go a long way in boosting memory.

The key is to deliver a tiny pulse of electricity to exactly the right place at exactly the right moment, a team reports in Tuesday's Nature Communications.

"We saw a 15 percent improvement in memory," says Michael Kahana, a professor of psychology at the University of Pennsylvania and an author of the study.

When Sarah Jay had her first seizure, she was in her mid-20s and working a high-stress job at a call center in Springfield, Mo.

"I was going to go on break," she says. "I was heading towards the bathroom and then I fell and passed out."

Scientists have found specialized brain cells in mice that appear to control anxiety levels.

The finding, reported Wednesday in the journal Neuron, could eventually lead to better treatments for anxiety disorders, which affect nearly 1 in 5 adults in the U.S.

Older brains may forget more because they lose their rhythm at night.

During deep sleep, older people have less coordination between two brain waves that are important to saving new memories, a team reports in the journal Neuron.

All this week we are talking to our friends here at NPR about their favorite things from 2017. And we're nerding out here. These are not, like, simple best-of lists.

You're in your car, heading for an intersection. The light turns yellow, so you decide to hit the gas. Then you see a police car.

Almost instantly, you know that stomping on the accelerator is a big mistake. But there's a good chance you'll do it anyway, says Susan Courtney, a professor in the Department of Psychological & Brain Sciences at Johns Hopkins University.

People who experience frequent migraines may soon have access to a new class of drugs.

In a pair of large studies, two drugs that tweak brain circuits involved in migraine each showed they could reduce the frequency of attacks without causing side effects, researchers report in the New England Journal of Medicine.
