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.

Larry Goldstein is trying to find drugs to treat Alzheimer's disease. A biologist in cellular and molecular medicine at the University of California, San Diego, Goldstein also just started testing something he hopes will enable paralyzed people to walk again.

For both lines of research, he's using cells from aborted fetuses.

"The fetal cells are vital at this time because, to our knowledge, they have the best properties for the kinds of experiments that we need to do," Goldstein says.

Remember Pig-Pen? The little kid from Charles Schulz's Peanuts cartoons who walked around in a cloud of dirt? Well, the human body does spew a cloud, but instead of dirt it contains millions of microorganisms.

"It turns out that that kid is all of us," says James Meadow, a microbial ecologist who led research about the microbes shadowing us during postdoctoral work at the University of Oregon. "It's just a microscopic cloud that's really hard to see."

After their third son was born, Tisha Scott and her husband decided they were done having kids. So Scott, 34, of Drakesville, Iowa, decided to get her tubes tied.

"As old married people, neither of us was really interested in using condoms for the rest of our life," Scott says. "So that was the decision that we made because we knew that our family was complete."

British scientists announced Friday that they had applied for permission to edit the DNA in human embryos, a controversial step that has provoked intense debate around the world.

Kathy Niakan of The Francis Crick Institute in London and colleagues filed an application with the Human Fertilisation and Embryology Authority (HFEA), which regulates experiments involving human embryos in England.

Last year's flu vaccine didn't work very well. This year's version should do a much better job protecting people against the flu, federal health officials said Thursday.

An analysis of the most common strains of flu virus that are circulating in the United States and elsewhere found they match the strains included in this year's vaccine, the federal Centers for Disease Control and Prevention said.

For the first time, the Food and Drug Administration has ordered a major tobacco company to stop selling several types of cigarettes.

The FDA on Tuesday ordered the R.J. Reynolds Tobacco Company to stop selling four products: Camel Bold Crush, Vantage Tech 13 and the regular and menthol versions of Pall Mall Deep Set Recessed Filter cigarettes.

Cutting blood pressure below the currently recommended target can significantly reduce the rate of heart attacks, strokes, heart failure and deaths, federal health officials reported Friday.

The findings come from the largest study ever conducted to examine whether reducing systolic blood pressure — the top number patients get when examined — below the currently recommended goal would be beneficial.

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 controversial decision was hailed by some doctors and advocates as a long-sought victory for women's health, but was condemned by others as irresponsible and dangerous.

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.
