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.

It's almost impossible to ignore a screaming baby. (Click here if you doubt that.) And now scientists think they know why.

"Screams occupy their own little patch of the soundscape that doesn't seem to be used for other things," says David Poeppel, a professor of psychology and neuroscience at New York University and director of the Department of Neuroscience at the Max Planck Institute in Frankfurt.

Researchers have taken another step toward reversing deafness using gene therapy.

The latest success involves mice with an inherited form of deafness, a team reports Wednesday in the journal Science Translational Medicine. And a similar approach is already being tried in people with hearing loss caused by damage to cells in the inner ear.

If you run into an old friend at the train station, your brain will probably form a memory of the experience. And that memory will forever link the person you saw with the place where you saw him.

Hollywood's version of science often asks us to believe that dinosaurs can be cloned from ancient DNA (they can't), or that the next ice age could develop in just a few days (it couldn't).

But Pixar's film Inside Out is an animated fantasy that remains remarkably true to what scientists have learned about the mind, emotion and memory.

If you give a chimp an oven, he or she will learn to cook.

That's what scientists concluded from a study that could help explain how and when early humans first began cooking their food.

Antidepressant drugs that work in hours instead of weeks could be on the market within three years, researchers say.

"We're getting closer and closer to having really, truly next-generation treatments that are better and quicker than existing ones," says Dr. Carlos Zarate, a researcher at the National Institute of Mental Health.

When Sam Swiller used hearing aids, his musical tastes ran to AC/DC and Nirvana — loud bands with lots of drums and bass. But after Swiller got a cochlear implant in 2005, he found that sort of music less appealing.

"I was getting pushed away from sounds I used to love," he says, "but also being more attracted to sounds that I never appreciated before." So he began listening to folk and alternative music, including the Icelandic singer Bjork.

When the brain needs to remember a phone number or learn a new dance step, it creates a circuit by connecting different types of neurons.

Scientists still don't know how many types of neurons there are or exactly what each type does.

On April 27, 1865, the steamboat Sultana exploded and sank while traveling up the Mississippi River, killing an estimated 1,800 people.

The event remains the worst maritime disaster in U.S. history (the sinking of the Titanic killed 1,512 people). Yet few know the story of the Sultana's demise, or the ensuing rescue effort that included Confederate soldiers saving Union soldiers they might have shot just weeks earlier.

The simple act of thinking can accelerate the growth of many brain tumors.

That's the conclusion of a paper in Cell published Thursday that showed how activity in the cerebral cortex affected high-grade gliomas, which represent about 80 percent of all malignant brain tumors in people.
