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.

It may be possible to transmit Alzheimer's disease from one person to another, according to a study published Wednesday in Nature. But this would occur only in highly unusual circumstances involving direct exposure to brain tissue, scientists say.

Oliver Sacks, a neurologist and best-selling author who explored the human brain one patient at a time, has died of cancer. He was 82.

Sacks was best known for his books The Man Who Mistook His Wife for a Hat and Awakenings, which became a 1990 feature film starring Robin Williams and Robert De Niro.

It's time for consumers to wake up to the risks of sleep disorders, scientists say.

Lihong Wang creates the sort of medical technology you'd expect to find on the starship Enterprise.

Wang, a professor of biomedical engineering at Washington University in St. Louis, has already helped develop instruments that can detect individual cancer cells in the bloodstream and oxygen consumption deep within the body. He has also created a camera that shoots at 100 billion frames a second, fast enough to freeze an object traveling at the speed of light.

The face of Alzheimer's isn't always old. Sometimes it belongs to someone like Giedre Cohen, who is 37, yet struggles to remember her own name.

Until about a year ago, Giedre was a "young, healthy, beautiful" woman just starting her life, says her husband, Tal Cohen, a real estate developer in Los Angeles. Now, he says, "her mind is slowly wasting away."

People like Giedre have a rare gene mutation that causes symptoms of Alzheimer's to appear before they turn 60.

There's new evidence suggesting that women's brains are especially vulnerable to Alzheimer's disease and other problems with memory and thinking.

Women with mild cognitive impairment, which can lead to Alzheimer's, tend to decline faster than men, researchers reported this week at the Alzheimer's Association International Conference in Washington, D.C.

Efforts to find a treatment for Alzheimer's disease have been disappointing so far. But there's a new generation of drugs in the works that researchers think might help not only Alzheimer's patients, but also people with Parkinson's disease and other brain disorders.

It's almost impossible to ignore a screaming baby. (Click here if you doubt that.) And now scientists think they know why.

"Screams occupy their own little patch of the soundscape that doesn't seem to be used for other things," says David Poeppel, a professor of psychology and neuroscience at New York University and director of the Department of Neuroscience at the Max Planck Institute in Frankfurt.

Researchers have taken another step toward reversing deafness using gene therapy.

The latest success involves mice with an inherited form of deafness, a team reports Wednesday in the journal Science Translational Medicine. And a similar approach is already being tried in people with hearing loss caused by damage to cells in the inner ear.
