Jon Hamilton

Jon Hamilton has served as a correspondent for NPR's science desk since 1998. His current beat includes neuroscience, health risks, behavior, and bioterrorism. Recent pieces include a series on the chemical perchlorate, which is turning up in California's water supply; a government effort to find out just how many autistic children there are in the U.S.; and an exploration of "neuromarketing."

Before joining NPR in 1998, Hamilton was a media fellow with the Henry J. Kaiser Family Foundation studying health policy issues. He completed a project on states that have radically changed 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 B.A. 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, won the Baker Prize for magazine writing, and earned a Sherwood traveling fellowship.

High-Def Storm Models Yielded Accurate Predictions

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.

As part of NPR's coverage of this year's presidential election, All Things Considered asked three science reporters to weigh in on the race. The result is a three-part series on the science of leadership. In Part 1, Alix Spiegel looked at the personalities of American presidents.

Voters could learn some things about choosing a leader from a fish. Or a chimp. Or an elephant.

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."

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.
