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.

Teenage Brains Are Malleable And Vulnerable, Researchers Say

Brain scans are showing researchers why it's important to treat problems like depression in teens.

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.

Ketamine Relieves Depression By Restoring Brain Connections

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

Canned food is a source of BPA exposure, but researchers aren't sure whether it causes childhood obesity. Above, the soup isle at a grocery store in Washington, D.C.

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.

CDC Recommends Hepatitis C Testing For All Boomers

Originally published on Thu August 16, 2012 4:19 pm

Listen up, baby boomers. The government wants every one of you to get tested for the hepatitis C virus.

The Centers for Disease Control and Prevention made a sweeping recommendation official amid growing concern about the estimated 2 million boomers infected with the virus, which can cause cirrhosis and liver cancer. The advice was published in the latest Morbidity and Mortality Weekly Report.

Fukushima Nuclear Disaster Exposed Nearby City To Little Radiation

After a tsunami disabled the Fukushima Dai-ichi plant in March of 2011, residents of the nearby city of Minamisoma, just 14 miles from the plant, were evacuated.

But within a few months, most returned to their homes. Still, many communities near the plant have remained skeptical and concerned about possible radiation exposure.

To find out how much radiation exposure these people have received, Japanese researchers measured levels of radioactive cesium in nearly 10,000 residents starting six months after the incident.

Another once-promising Alzheimer's drug has just been tossed on the pharmaceutical scrap heap.

This time it's a drug called bapineuzumab. Like several previous experimental drugs, it was designed to attack the plaques that build up in the brains of people with Alzheimer's.

And like those earlier drugs, it failed.
