Rob Stein

Rob Stein is a correspondent and senior editor on NPR's science desk.

An award-winning science journalist with more than 25 years of experience, Stein mostly covers health and medicine. He tends to focus on stories that illustrate the intersection of science, health, politics, social trends, ethics, and federal science policy. He tracks genetics, stem cells, cancer research, women's health issues and other science, medical, and health policy news.

Before NPR, Stein worked at The Washington Post for 16 years, first as the newspaper's science editor and then as a national health reporter. Earlier in his career, Stein spent about four years as an editor at NPR's science desk. Before that, he was a science reporter for United Press International (UPI) in Boston and the science editor of the international wire service in Washington.

Stein is a graduate of the University of Massachusetts, Amherst. He completed a journalism fellowship at the Harvard School of Public Health, a program in science and religion at the University of Cambridge, and a summer science writer's workshop at the Marine Biological Laboratory in Woods Hole, Mass.

Stein's work has been honored by many organizations, including the National Academy of Sciences, the American Association for the Advancement of Science and the Association of Health Care Journalists.

A prominent scientist has started a big new debate about breast cancer. Geneticist Mary-Claire King of the University of Washington, who identified the first breast cancer gene, is recommending that all women get tested for genetic mutations that can cause breast cancer.

Scientists are reporting strong evidence that the experimental Ebola drug ZMapp may be effective for treating victims of the devastating disease.

A study involving 18 rhesus macaque monkeys, published Friday in the journal Nature, found that the drug saved 100 percent of the animals even if they didn't receive the drug until five days after they had been infected. The study is the first to test ZMapp in a primate, which is considered a good model for how a drug might work in humans.

The Ebola outbreak has set off an alarm around the world. Public health leaders say the intense concern is appropriate, given the unprecedented size of the outbreak and the deadliness of the virus.

But experts say the outbreak has also produced a lot of unfounded fears. Even just the word Ebola is kind of terrifying.

Why? Well, Hollywood has a lot to do with it.

Vicki Hornbuckle used to play the piano at her church. But that was before her liver started failing.

"I had to give it up because I couldn't keep up," says Hornbuckle, 54, of Snellville, Georgia. "I didn't have the energy to do three services on Sunday. You're just too tired to deal with anything. And so, it's not a life that you want to live."

But Hornbuckle hasn't given up. She's fighting to stay alive long enough to get a liver transplant.

Basic biology has it that girls are girls because they have two X chromosomes — the things inside cells that carry our genes. Boys are boys because they have one X and one Y. Recently, though, there's been a lot of debate in scientific circles about the fate of that Y chromosome — the genetic basis of maleness.

People often talk about how their friends feel like family. Well, there's some new research out that suggests there's more to that than just a feeling. People appear to be more like their friends genetically than they are to strangers, the research found.

A prestigious scientific journal Wednesday took the unusual step of retracting some high-profile research that had generated international excitement about stem cell research.

The British scientific journal Nature retracted two papers published in January by scientists at the Riken research institute in Japan and at Harvard Medical School that claimed that they could create stem cells simply by dipping skin and blood cells into acid.

Government warnings that antidepressants may be risky for adolescents, and the ensuing media coverage, appear to have caused an increase in suicide attempts among young people, researchers reported Wednesday.

A study involving the health records of more than 7 million people between 2000 and 2010 found a sharp drop in antidepressant use among adolescents and young people and a significant increase in suicide attempts after the Food and Drug Administration issued its warnings.

An alarm sounds on Ed Damiano's night stand in the middle of the night. He jumps out of bed and rushes into his son's room next door.

His son, David, has Type 1 diabetes. The 15-year-old sleeps hooked up to a monitor that sounds an alarm when his blood sugar gets too low. If it drops sharply, David could die in his sleep.

"The fear is that there's going to be this little cold limb, and I screwed up. It's all on me," Damiano says.

But when he touches David's hand, he's warm. He's OK. Damiano says, "That's the moment of relief."

Cigarette smoking among U.S. high school students has dropped to the lowest level in 22 years, federal health officials reported Thursday.

The percentage of students who reported smoking a cigarette at least one day in the last 30 days fell to 15.7 percent in 2013, according to the National Youth Risk Behavior Survey, a large federal survey that has been tracking youth smoking since 1991.
