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.

How You Move Your Arm Says Something About Who You Are

Researchers studying brains want to know what's happening in an area called the premotor cortex — the place in the brain that gears up for something the body is about to do, like swimming.

When Olympic swimmer Michael Phelps steps onto a starting block a few days from now, a Stanford scientist named Krishna Shenoy will be asking himself a question: "What's going on in Michael Phelps' brain?"

Specifically, Shenoy would like to know what's happening in an area called the premotor cortex. This area doesn't directly tell muscles what to do. But it's the place where the brain gears up for something the body is about to do, like swimming.

Finally, there's some good news about Alzheimer's disease.

It turns out that a few lucky people carry a genetic mutation that greatly reduces their risk of getting the disease, an Icelandic team reports in the journal Nature.

The mutation also seems to protect people who don't have Alzheimer's disease from the cognitive decline that typically occurs with age.

Common Parasite May Influence Human Behavior

Originally published on Tue July 3, 2012 5:06 pm

Transcript

MELISSA BLOCK, HOST:

Scientists say a parasite carried by cats appears to influence the behavior of humans, in this case, women infected with the parasite were slightly more likely to attempt suicide.

NPR's Jon Hamilton reports this is just the latest study suggesting that parasites can cause subtle changes in our brains.

JON HAMIILTON, BYLINE: This parasite is called Toxoplasma and its primary home is in the intestine of a cat. People can get infected when they eat under-cooked meats or sometimes when they change the litter in a cat box.

There's fresh evidence that cats can be a threat to your mental health.

To be fair, it's not kitties themselves that are the problem, but a parasite they carry called Toxoplasma gondii.

A study of more than 45,000 Danish women found that those infected with this feline parasite were 1.5 times more likely to attempt suicide than women who weren't infected.
