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.

There's new evidence that widely prescribed testosterone drugs — touted for men with flagging libidos and general listlessness — might increase the risk of heart attacks.

When you take a pill, you and your doctor hope it will work — and that helps it work.

That's not a new idea. But now researchers say they know just how much of a drug's effect comes from the patient's expectation: at least half.

When patients in the midst of a migraine attack took a dummy pill they thought was a widely used migraine drug, it reduced their pain roughly as much as when they took the real drug thinking it was a placebo.

Saturday marks an important milestone in public health – the 50th anniversary of the first Surgeon General's Report on Smoking and Health.

Few if any documents have had the impact of this one — both on the amount of disease and death prevented, and on the very scope of public health.
