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.

Experts Argue Against Proposed Ban On Vaccine Preservative

A boy in Lima, Peru, receives a hepatitis B vaccine during an immunization drive in 2008. The United Nations is considering a ban on the preservative thimerosal, which is often used in hepatitis B and other vaccines in developing countries.

An old complaint about the safety of childhood vaccines is finding new life at the United Nations.

The U.N. Environment Program is considering a ban on thimerosal, a vaccine preservative that is widely used in developing countries. The program expects to make a decision sometime after a final meeting on the issue in January.

Matching DNA With Medical Records To Crack Disease And Aging

A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. And it's all possible because 100,000 people agreed to contribute some saliva in the name of science.

The same brain system that controls our muscles also helps us remember music, scientists say.

When we listen to a new musical phrase, it is the brain's motor system — not areas involved in hearing — that helps us remember what we've heard, researchers reported at the Society for Neuroscience meeting in New Orleans last month.

While New York City and other places along the Northeast coast are still recovering from Superstorm Sandy, they're also looking ahead to how they can prevent flooding in the future, when sea level rise will make the problem worse. They may be able to take some lessons from coastal Norfolk, Va., which is far ahead of most cities when it comes to flood protection.

Norfolk, Va., Puts Flooding Survival Plan To The Test

Superstorm Sandy got officials in New York and New Jersey talking about how to prevent flooding in a time of global warming and sea level rise.

But the place on the East Coast that's most vulnerable to flooding is several hundred miles south, around Norfolk, Va. — and Norfolk has already spent many years studying how to survive the rising waters.

Scientists say what Norfolk has learned is especially important in light of new research showing that the coastline from North Carolina to Boston will experience even more sea level rise than other areas.

High-Def Storm Models Yielded Accurate Predictions

These computer models from Oct. 26 of then-Hurricane Sandy show different predictions for the storm's path.

Better satellites, smarter computer models and faster computers helped government forecasters correctly predict the devastation from Hurricane Sandy, scientists say.

It's unlikely the forecast would have been nearly as accurate just a couple of decades ago, they say.

"The National Hurricane Center did a fantastic job, particularly with the track forecast and the intensity forecast as it was moving toward the Northeast," says Sharan Majumdar, an associate professor of meteorology and physical oceanography at the University of Miami.

Storm's Uncertain Track Defies Weather Rules

It's still unclear whether Sandy will be a devastating storm or just a bad one.

It is clear, however, that Sandy will be remembered as the storm that broke all the rules and baffled the nation's top weather forecasters.

Early Saturday morning, the National Weather Service downgraded the storm from a hurricane to a tropical storm — only to return it to hurricane status a few hours later. Either way, forecasters warn, "widespread impacts" are expected along the coast.

Treatment For Alzheimer's Should Start Years Before Disease Sets In

Treatment for Alzheimer's probably needs to begin years or even decades before symptoms of the disease start to appear, scientists reported at this week's Society for Neuroscience meeting in New Orleans.

"By the time an Alzheimer's patient is diagnosed even with mild or moderate Alzheimer's there is very, very extensive neuron death," said John Morrison of Mount Sinai Medical School in New York. "And the neurons that die are precisely those neurons that allow you to navigate the world and make sense of the world."

Adolescent brains have gotten a bad rap, according to neuroscientists.

It's true that teenage brains can be impulsive, scientists reported at the Society for Neuroscience meeting in New Orleans. But adolescent brains are also vulnerable, dynamic and highly responsive to positive feedback, they say.

Even extreme stress doesn't have to get you down.

That's the message from brain scientists studying the relationship between stress and problems such as depression, anxiety and post traumatic stress disorder, or PTSD.

Researchers at the Society for Neuroscience meeting in New Orleans presented studies showing how stress caused by everything from battlefield trauma to bullying can alter brain circuitry in ways that have long-term effects on mental health.

Scientists say they have figured out how an experimental drug called ketamine is able to relieve major depression in hours instead of weeks.

Researchers from Yale and the National Institute of Mental Health say ketamine seems to cause a burst of new connections to form between nerve cells in parts of the brain involved in emotion and mood.

Researchers have found the first drug to treat progeria, an extremely rare genetic disease that causes children to age so rapidly that many die in their teens.

The drug, called lonafarnib, is not a cure. But in a study published Monday of 28 children, it reversed changes in blood vessels that usually lead to heart attacks and strokes.

An experimental drug that helps people who have Fragile X syndrome is raising hopes of a treatment for autism.

The drug, called arbaclofen, made people with Fragile X less likely to avoid social interactions, according to a study in Science Translational Medicine. Researchers suspect it might do the same for people with autism.

Link Between BPA And Childhood Obesity Is Unclear

BPA could be making kids fat. Or not.

That's the unsatisfying takeaway from the latest study on bisphenol A — the plastic additive that environmental groups have blamed for everything from ADHD to prostate disease.

Unfortunately, the science behind those allegations isn't so clear. And the new study on obesity in children and teens is no exception.
