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.

Seeing Less Helps The Brain Hear More

A few days in the dark can improve an animal's hearing, scientists report this week in the journal Neuron. This temporary loss of visual input seems to trigger favorable changes in areas of the brain that process auditory information, they say.

Researchers Watch As Our Brains Turn Sounds Into Words

Katherine Streeter for NPR

Originally published on Fri January 31, 2014 6:19 pm

Researchers are a bit closer to understanding one of the brain's greatest accomplishments: making sense out of spoken language.

An area of the brain that interprets speech contains cells that respond to the dozen or so basic units of sound we use to form words, according to a team from the University of California, San Francisco.

Some of these cells respond specifically to plosives, like the initial "puh" sounds in "Peter Piper picked a peck of pickled peppers," the team found. Other neurons respond to fricative consonants, like the "f" sound in the word "fish."

Stricter Autism Criteria Unlikely To Reduce Services For Kids

Clinical specialist Catey Funaiock took notes while observing a 5-year-old boy at the Marcus Autism Center, part of Children's Healthcare of Atlanta, in September.

The clinical definition for when a child has some form of autism has been tightened. And these narrower criteria for autism spectrum disorder probably will reduce the number of kids who meet the new standard.

But researchers say the changes, which were rolled out last May, are likely to have a bigger effect on government statistics than on the care of the nation's children.

Want to get away? Thinking about a place with warm water and soft sand? Sounds nice. But think twice before you wade into that inviting surf. Chances are there are stingrays in the area.

Every year, these timid, shellfish-eating cousins of the shark inflict excruciating injuries on thousands of swimmers and surfers from the Bahamas to Bahrain to both coasts of the United States.

Can A Fruit Fly Help Explain Autism?

A newly discovered neural circuit in the brain of the common fruit fly seems to serve as a sort of "volume control," turning up and down the perception of sound and light.

For President Obama, 2013 wasn't just the year of Obamacare. It was also the year of the brain.

In April, Obama announced his Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative — an effort to unlock "the mystery of the three pounds of matter that sits between our ears."

Experimental Tool Uses Light To Tweak The Living Brain

A technique called optogenetics is being used in the laboratory to observe and control what brain circuits are doing in real time.

When President Obama announced his BRAIN Initiative in April, he promised to give scientists "the tools they need to get a dynamic picture of the brain in action."

An early version of one of those tools already exists, scientists say. It's a relatively new set of techniques called optogenetics that allows researchers to control the activity of brain cells using light.

Could Pot Help Veterans With PTSD? Brain Scientists Say Maybe

There's data to support the notion that pot, or a drug based on its active ingredient, could help ease the fears of PTSD.

Veterans who smoke marijuana to cope with post-traumatic stress disorder may be onto something. There's growing evidence that pot can affect brain circuits involved in PTSD.

'Forecast Bust:' Why 2013 Hurricane Predictions Were So Wrong

Originally published on Fri November 29, 2013 5:49 pm

Transcript

ARI SHAPIRO, BYLINE: It's ALL THINGS CONSIDERED from NPR News. I'm Ari Shapiro. The 2013 Atlantic hurricane season ends tomorrow. It'll be remembered as one of the quietest on record. Since June, there have been just two hurricanes, both were relatively weak. As NPR's Jon Hamilton reports, forecasters were expecting something very different.

JON HAMILTON, BYLINE: The National Oceanic and Atmospheric Administration told Americans to expect an unusually active year with between seven and 11 hurricanes. Other forecasters offered variations on that theme.

Brain Cells 'Geotag' Memories To Cache What Happened — And Where

Benjamin Arthur for NPR

Originally published on Mon December 2, 2013 5:13 am

Think back to an important event in your life: a graduation, a birth, a special Thanksgiving dinner. Chances are you're remembering not only what happened, but also where it happened. And now scientists think they know why.

As we form so-called episodic memories, the brain appears to be using special cells in the hippocampus to "geotag" each event, researchers report in Science. The process is similar to what some digital cameras do when they tag each picture with information about where the image was taken.
