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.

The Food and Drug Administration is relaxing a 32-year-old ban on blood donations from gay and bisexual men.

The FDA announced Monday that it was replacing a lifetime prohibition with a new policy that will allow gay and bisexual men to donate blood, but only if they have not had sexual contact with another man for at least one year.

Medical advisers to the Food and Drug Administration say that prescription drugs containing codeine should not be used to treat children or the majority of teens suffering from pain or a cough.

In their meeting Thursday, the advisers also voted overwhelmingly against the over-the-counter sales of codeine-containing cough syrup for children. Selling such products without a prescription is currently permitted in 28 states and the District of Columbia.

When police investigate suspicious deaths, one of the key questions is: When did the victim die?

A study published Thursday in Science may lead forensics experts and detectives to a more precise answer in the future.

Researchers studying the microbes on decomposing bodies have found that the mix of bacteria and other organisms on dead bodies changes over time in a clear pattern.

Since 2003, strict rules have limited how long medical residents can work without a break. The rules are supposed to minimize the risk that these doctors-in-training will make mistakes that threaten patients' safety because of fatigue.

But are these rules really the best for new doctors and their patients? There's been intense debate over that and some say little data to resolve the question.

So a group of researchers decided to follow thousands of medical residents at dozens of hospitals around the country.

Global warming isn't the only vexing issue the world wrestled with this week.

While delegates gathered in Paris to discuss climate change, the International Summit on Human Gene Editing convened in Washington, D.C., to debate another conundrum: How far should scientists go when editing human DNA?
