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.

AIDS Scientists Encouraged By Antibodies That Hit Monkey Virus

These HIV viruses even look a little like bull's-eyes.
A. Harrison and P. Feorino CDC

Originally published on Thu October 31, 2013 12:15 pm

Scientists have a new idea for beating HIV: Target the virus with guided missiles called monoclonal antibodies.

At least in monkeys infected with an experimental virus similar to the human AIDS virus, the approach produced what researchers call "profound therapeutic efficacy."

A Toddler Remains HIV-Free, Raising Hope For Babies Worldwide

A 3-year-old girl born in Mississippi with HIV acquired from her mother during pregnancy remains free of detectable virus at least 18 months after she stopped taking antiviral pills.

New results on this child, published online by the New England Journal of Medicine, appear to green-light a study in the advanced planning stages in which researchers around the world will try to replicate her successful treatment in other infected newborns.

To Prevent HIV Infection, Couples Try Testing Together

Getting tested for HIV in the U.S. is almost always private, sometimes even secretive. Ditto for disclosing the results.

But some say the approach is outmoded at a time when many at risk for HIV — gay men — are in committed relationships.

Research shows as many as two-thirds of new HIV infections among gay men these days are within committed couples. That's very different from the days when promiscuity fueled the epidemic.

Human rights activists are suing the United Nations on behalf of five Haitian families afflicted by cholera — a disease many believe U.N. peacekeeping troops brought to Haiti in the aftermath of the devastating 2010 earthquake there.

Some Online Journals Will Publish Fake Science, For A Fee

You could do all that brain work. Or you could make it up.

Originally published on Fri October 4, 2013 7:34 am

Many online journals are ready to publish bad research in exchange for a credit card number.

That's the conclusion of an elaborate sting carried out by Science, a leading mainline journal. The result should trouble doctors, patients, policymakers and anyone who has a stake in the integrity of science (and who doesn't?).

The business model of these "predatory publishers" is a scientific version of those phishes from Nigerians who want help transferring a few million dollars into your bank account.

For A Price, Volunteers Endure Scientists' Flu Spritzes

How much would a scientist have to pay you to get sick with the flu?

Originally published on Thu September 26, 2013 12:01 pm

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.

Even As MERS Epidemic Grows, The Source Eludes Scientists

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.

Healthful Living May Lengthen Telomeres And Lifespans

Originally published on Tue September 17, 2013 12:22 pm

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 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.

The Centers for Disease Control and Prevention says 300,000 Americans are getting Lyme disease every year, and the toll is growing.

"It confirms what we've thought for a long time: This is a large problem," Dr. Paul Mead tells Shots. "The bottom line is that by defining how big the problem is we make it easier for everyone to figure out what kind of resources we have to use to address it."

HPV Vaccination Might Help Reduce Risk Of Throat Cancers

Vaccines against the HPV virus are already used to prevent cervical and anal cancer.
Harry Cabluck AP

Originally published on Tue July 23, 2013 1:29 pm

A study of women in Costa Rica is raising hope that getting vaccinated against the human papillomavirus, or HPV, could lower the risk of throat cancers.

The research doesn't show that. It would take a much bigger and longer study to do that – if such a study could ethically be done at all.

What this study does show is that among the nearly 6,000 women in the study, those who got vaccinated against two strains of the virus had 93 percent fewer HPV throat infections four years later.
