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.

What would it take to persuade you to allow government researchers to squirt millions of live flu viruses up your nose?

A recently concluded project at the National Institutes of Health found, among other things, that $3,400 each was enough to attract plenty of volunteers.

"I am happy I could contribute in some way," says Kelli Beyer, 24, one of 46 healthy people who volunteered for the project. To get the money, the research subjects had to commit to several days of testing, then nine days in a hospital isolation ward once the virus was administered in a nasal spray.

Despite a plateau in funding by international donors, the United Nations AIDS agency reports striking progress in curbing new HIV infections and deaths from AIDS.

A year after doctors first identified an illness that came to be known as Middle Eastern Respiratory Syndrome researchers are reporting fresh genetic information about the virus that causes it.

The findings don't bring scientists any closer to understanding where MERS is coming from. In fact, the main news is that researchers were wrong about the source of some infections in the largest cluster of cases so far.

Scientists claim they have evidence that explains why lifestyle changes known to be good for you — low-fat diets, exercise, reducing stress — can lengthen your life.

Based on a small, exploratory study, researchers say these good habits work by preventing chromosomes in our cells from unraveling. Basically, they assert that healthy living can reverse the effects of aging at a genetic level.

A 4-year-old child who died of a rare brain infection in early August has led Louisiana health officials to discover that the cause is lurking in the water pipes of St. Bernard Parish, southeast of New Orleans.

Malaria researchers have developed what they consider a crucial advance: Simple and fast tests that can tell when parasites have become resistant to the front-line drug against malaria.

Taken together, these tests give humans a new tool to counter the malaria parasite's ability to outwit every drug that's ever been devised against it.

An aggressive approach to preventing heart attacks could be the next big thing in the long battle against this leading cause of death.

A British study presented Sunday in Amsterdam finds that doctors can reduce future heart attacks and cardiac deaths by opening up multiple clogged coronary arteries while they're fixing the artery that's causing a heart attack in progress.

Mental disorders and substance abuse are the leading causes of nonfatal illness on the planet, according to an ambitious analysis of data from around the world.

A companion report, the first of its kind, documents the global impact of four illicit drugs: heroin and other opiates, amphetamines, cocaine and cannabis. It calls illegal drugs "an important contributor to the global burden of disease."

The two papers are being published by The Lancet as part of a continuing project called the Global Burden of Disease.

A 7-year-old vaccine that has drastically cut intestinal infections in infants is benefiting the rest of America, too.

A study published Tuesday from the Centers for Disease Control and Prevention shows that vaccinating infants against rotavirus has also caused a striking decline in serious infections among older children and adults who didn't get vaccinated.

It's been a long and often controversial road, but U.S. doctors are finally embracing a drug that can halt strokes and prevent disabling brain damage.

An analysis of more than 1 million stroke patients shows that use of the 17-year-old drug, called alteplase (brand-name Activase), nearly doubled between 2003 and 2011.
