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.

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.

The Pentagon has quietly sidelined a program that placed blast gauges on thousands of combat troops in Afghanistan.

NPR has learned the monitoring was discontinued because the gauges failed to reliably show whether service members had been close enough to an explosion to have sustained a concussion, or mild traumatic brain injury.

Forget where you just left your car keys? A magnetic pulse might help you remember.

Some dormant memories can be revived by delivering a pulse of magnetic energy to the right brain cells, researchers report Thursday in the journal Science.

The finding is part of a study that suggests the brain's "working memory" system is far less volatile than scientists once thought.

A nonprofit research group is giving scientists a new way to study the secret lives of human cells.

On Wednesday, the Allen Institute for Cell Science provided access to a collection of living stem cells that have been genetically altered to make internal structures like the nucleus and mitochondria glow.

You may not remember what you were doing a few minutes ago. But your dog probably does.

A study of 17 dogs found they could remember and imitate their owners' actions up to an hour later. The results, published Wednesday in Current Biology, suggest that dogs can remember and relive an experience much the way people do.

There's new evidence that excessive screen time early in life can change the circuits in a growing brain.

Scientists disagree, though, about whether those changes are helpful, or just cause problems. Both views emerged during the Society for Neuroscience meeting in San Diego this week.

Some tiny clusters of brain cells grown in a lab dish are making big news at this week's Society for Neuroscience meeting in San Diego.

Known as "minibrains," these rudimentary networks of cells are small enough to fit on the head of a pin, but already are providing researchers with insights into everything from early brain development to Down syndrome, Alzheimer's and Zika.

Twelve years ago, a car wreck took away Nathan Copeland's ability to control his hands or sense what his fingers were touching.

A few months ago, researchers at the University of Pittsburgh and the University of Pittsburgh Medical Center gave Copeland a new way to reach out and feel the world around him. It's a mind-controlled robotic arm that has pressure sensors in each fingertip that send signals directly to Copeland's brain.

Want to be smarter? More focused? Free of memory problems as you age?

If so, don't count on brain games to help you.

That's the conclusion of an exhaustive evaluation of the scientific literature on brain training games and programs. It was published Monday in the journal Psychological Science in the Public Interest.

What rats can remember may help people who forget.

Researchers are reporting evidence that rats possess "episodic memories," the kind of memories that allow us to go back in time and recall specific events. These memories are among the first to disappear in people who develop Alzheimer's disease.

The finding, which appears Thursday in Current Biology, suggests that rats could offer a better way to test potential drugs for Alzheimer's. Right now, most of these drugs are tested in mice.

There's growing evidence that a physical injury to the brain can make people susceptible to post-traumatic stress disorder.
