Richard Knox

Since he joined NPR in 2000, Knox has covered a broad range of issues and events in public health, medicine, and science. His reports can be heard on NPR's Morning Edition, All Things Considered, Weekend Edition, Talk of the Nation, and newscasts.

Among other things, Knox's NPR reports have examined the impact of HIV/AIDS in Africa, North America, and the Caribbean; anthrax terrorism; smallpox and other bioterrorism preparedness issues; the rising cost of medical care; early detection of lung cancer; community caregiving; music and the brain; and the SARS epidemic.

Before joining NPR, Knox covered medicine and health for The Boston Globe. His award-winning 1995 articles on medical errors are considered landmarks in the national movement to prevent medical mistakes. Knox is a graduate of the University of Illinois and Columbia University. He has held yearlong fellowships at Stanford and Harvard Universities, and is the author of a 1993 book on Germany's health care system.

He and his wife Jean, an editor, live in Boston. They have two daughters.

Researchers trudging down the long and twisted path toward an AIDS vaccine are encouraged by new studies that show an experimental vaccine protects monkeys against infection with a virus that is very similar to HIV.

If a heart attack sends you to an American hospital, you'll probably go home after only two or three nights. That's faster than virtually anyplace else in the world.

But your chances of needing to go back into the hospital within the next month are also higher than they are for heart attack patients in 16 other countries. That's the finding from a Duke University-led study in this week's JAMA, the Journal of the American Medical Association.

2011 has been a momentous year in the 30-year-old AIDS pandemic.

The big breakthrough was the discovery that antiviral drugs can prevent someone who's infected with HIV from passing the virus to others. It's nearly 100 percent effective. That led President Obama to declare earlier this month that the U.S. will expand HIV treatment in hard-hit countries by 50 percent.

Debra Meyerson was hiking near Lake Tahoe 15 months ago when a stroke destroyed part of the left side of her brain, leaving her literally speechless. It happens to more than 150,000 Americans a year.

But now Meyerson is learning to talk again through an approach that trains the undamaged right side of her brain to "speak." Specifically, it's a region that controls singing.

For more than 100 years, it's been known that people who can't speak after injury to the speech centers on the left side of the brain can sing.

Harvard researchers say they've uncovered a big problem among the nation's 700,000 police officers: a serious lack of sleep.

In what's believed to be the first study of its kind, the researchers queried nearly 5,000 municipal and state police officers in the U.S. and Canada about their sleep habits and symptoms of possible sleep disorders. Then they assessed their on-duty performance for two years.

Forty percent had sleep disorders, and the vast majority of these were undiagnosed before.

Doubts have been growing about Yasmin, Yaz and their sister contraceptives for several years now. And those doubts reached full flower at a Food Drug Administration advisory panel on Thursday.

A federally convened panel of experts says most men with newly diagnosed prostate cancer should be offered the chance to put off treatment in favor of medical monitoring of their condition.

In fact, the panel went so far as to say doctors should stop calling most of these low-risk tumors cancer at all.
