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 on Thursday ordered three tobacco companies to stop claiming their cigarettes are "additive-free" or "natural."

The agency said those claims could mislead smokers into thinking those cigarettes are safer than others.

The Food and Drug Administration approved the first drug designed to increase a woman's libido.

The assortment of microbes in a pregnant woman's vagina appears to play a role in her chances of giving birth prematurely, new research suggests.

The study of 49 pregnant women, published in this week's Proceedings of the National Academy of Sciences, found that those who had a diverse array of microbes were more likely to give birth prematurely.

Kevin Lopez remembers exactly when he knew he wasn't like his friends and family.

"It just hit me one day," he says. It was the morning he was picking out a shirt to wear for his first day of sixth grade. "I just looked at myself and I realized I was different."

Kevin was born missing the fingers on his right hand. His arm and wrist are fully developed, and he has most of a regular palm. But he just has nubs where his fingers should start.

Update 4:40 p.m.: The panel of advisers to the Food and Drug Administration voted 18 to 6 to recommend that the agency approve flibanserin, as long as there are measures in place to make sure that women are aware of its risks, including low blood pressure and fainting. The FDA doesn't have to follow the recommendations of its advisory panels but usually does.

A committee of medical advisers meets Thursday to consider whether to recommend that the Food and Drug Administration approve the first drug that aims to boost a woman's libido.
