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.

This is a story about a duck. More precisely, it's a story about what your brain just did when you read the word "duck."

Chances are, your brain created an image of a web-footed waterfowl. It also may have recalled the sound of quacking or the feel of feathers. And new research suggests that these mental simulations are essential to understanding language.

Mutations on a single gene appear to increase the risk for both an unusual sleep disorder and migraines, a team reports in Science Translational Medicine.

The finding could help explain the links between sleep problems and migraines. It also should make it easier to find new drugs to treat migraines, researchers say.

And for one member of the research team, Emily Bates, the discovery represents a personal victory.

When Superstorm Sandy inundated lower Manhattan last year, thousands of lab animals drowned and many scientists lost months or even years of work. One of those scientists is Gordon Fishell, a brain researcher at New York University.

Just hours before Sandy reached New York, Fishell says, he began to worry that animals housed in a basement below his lab were in danger. "I realized Hurricane Sandy and high tide were going to coincide at Battery Park, which is right where my lab is," he says.

A rat with some human genes could provide a better way to test Alzheimer's drugs.

The genetically modified rat is the first rodent model to exhibit the full range of brain changes found in Alzheimer's, researchers report in The Journal of Neuroscience.

One day in the fall of 2010, composer Richard Einhorn woke up and realized there was something horribly wrong with his hearing.

"There was an enormous, violent buzzing in my ears," he says. "And I realized that my right ear had gone completely deaf."

President Obama has announced an ambitious plan to explore the mysteries of the human brain.

In a speech Tuesday, Obama said he will ask Congress for $100 million in 2014 to "better understand how we think and how we learn and how we remember." Other goals include finding new treatments for Alzheimer's disease, epilepsy and traumatic brain injury.

A large new government study should reassure parents who are afraid that kids are getting autism because they receive too many vaccines too early in life.

The study, by researchers at the Center for Disease Control and Prevention, found no connection between the number of vaccines a child received and his or her risk of autism spectrum disorder. It also found that even though kids are getting more vaccines these days, those vaccines contain many fewer of the substances that provoke an immune response.

Loneliness hurts, but social isolation can kill you. That's the conclusion of a study of more than 6,500 people in the U.K.

The study, by a team at University College London, comes after decades of research showing that both loneliness and infrequent contact with friends and family can, independently, shorten a person's life. The scientists expected to find that the combination of these two risk factors would be especially dangerous.

As far back as he can remember, George McCann lived in fear. When he was asleep he would have horrific nightmares filled with violent images. When he was awake, he often felt threatened by people, including members of his own family. And when he felt threatened, he would become aggressive, even violent.

George spent his childhood certain that something very bad was going to happen. And when he was 12, it did. His unrelenting fears led to a violent outburst at school. And George landed in a psychiatric hospital.
