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.

A little spit may help predict whether a child's concussion symptoms will subside in days or persist for weeks.

A test that measures fragments of genetic material in saliva was nearly 90 percent accurate in identifying children and adolescents whose symptoms persisted for at least a month, a Penn State team told the Pediatric Academic Societies Meeting in San Francisco, Calif. In contrast, a concussion survey commonly used by doctors was right less than 70 percent of the time.

Tiny, 3-D clusters of human brain cells grown in a petri dish are providing hints about the origins of disorders like autism and epilepsy.

An experiment using these cell clusters — which are only about the size of the head of a pin — found that a genetic mutation associated with both autism and epilepsy kept developing cells from migrating normally from one cluster of brain cells to another, researchers report in the journal Nature.

People with a brain injury or dementia often struggle to remember simple things, like names or places. In research published Thursday in the journal Current Biology, scientists have shown it may be possible to improve this sort of memory using tiny pulses of electricity — if they're properly timed.

A typical person's ability to remember things tends to vary a lot, says Michael Kahana, who directs the computational memory lab at the University of Pennsylvania.

Most of us have about five dreams each night, though we're not likely to remember any of them.

But a team of researchers has found a pattern of brain activity that seems to reveal not only when the brain is generating a dream but something about the content of that dream.

The U.S. military is trying to figure out whether certain heavy weapons are putting U.S. troops in danger.

The concern centers on the possibility of brain injuries from shoulder-fired weapons like the Carl Gustaf, a recoilless rifle that resembles a bazooka and is powerful enough to blow up a tank.

Gerard Sanacora, a professor of psychiatry at Yale University, has treated hundreds of severely depressed patients with low doses of ketamine, an anesthetic and popular club drug that isn't approved for depression.

This sort of "off-label" prescribing is legal. But Sanacora says other doctors sometimes ask him, "How can you be offering this to patients based on the limited amount of information that's out there and not knowing the potential long-term risk?"

Sanacora has a simple answer.

Scientists are hoping that a single drug can treat two devastating brain diseases: Parkinson's and Alzheimer's.

The drug is nilotinib, which is approved to treat a form of leukemia.

An orangutan named Rocky is helping scientists figure out when early humans might have uttered the first word.

Rocky, who is 12 and lives at the Indianapolis Zoo, has shown that he can control his vocal cords much the way people do. He can learn new vocal sounds and even match the pitch of sounds made by a person.

Scientists may have solved the mystery of nodding syndrome, a rare form of epilepsy that has disabled thousands of children in East Africa.

Researchers have created mice that appear impervious to the lure of cocaine.

Even after the genetically engineered animals were given the drug repeatedly, they did not appear to crave it the way typical mice do, a team reports in Nature Neuroscience.

What Einstein did for physics, a Spaniard named Santiago Ramón y Cajal did for neuroscience more than a century ago.

Back in the 1890s, Cajal produced a series of drawings of brain cells that would radically change scientists' understanding of the brain.

And Cajal's drawings aren't just important to science. They are considered so striking that the Weisman Art Museum in Minneapolis has organized a traveling exhibition of Cajal's work called The Beautiful Brain.

There has been a lot of arguing about the size of crowds in the past few days. Estimates for President Trump's inauguration and the Women's March a day later vary widely.

Mice that kill at the flip of a switch may reveal how hunting behavior evolved hundreds of millions of years ago.

The mice became aggressive predators when two sets of neurons in the amygdala were activated with laser light, a team reported Thursday in the journal Cell.

A comparison of kid brains and grownup brains may explain why our ability to recognize faces keeps getting better until about age 30.

Brain scans of 25 adults and 22 children showed that an area devoted to facial recognition keeps growing long after adolescence, researchers report in the journal Science.

For patients with serious brain injuries, there's a strong link between sleep patterns and recovery.

A study of 30 patients hospitalized for moderate to severe traumatic brain injuries found that sleep quality and brain function improved in tandem, researchers reported Wednesday in the journal Neurology.
