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 scientist in Sweden has started trying to edit the DNA in healthy human embryos, NPR has learned.

The step by the developmental biologist Fredrik Lanner makes him the first researcher known to attempt to modify the genes of healthy human embryos. That has long been considered taboo because of safety and ethical concerns.

Hundreds of clinics around the country are offering to treat a long list of health problems with stem cells.

The clinics claim that stem cells found in fat tissue, blood, bone marrow and even placentas can help people suffering from arthritic joints and torn tendons to more serious medical problems, including spinal cord injuries, Parkinson's disease and strokes. Some even claim the cells can help children with autism.

But leading stem cell researchers say there's not enough evidence to support the clinics' claims.

Mosquitoes have begun spreading the Zika virus in a second part of Miami — the popular tourist destination of Miami Beach — Florida officials announced Friday.

When parents are trying to keep their children safe, one of the things many do is to transport their kids in a stroller or baby carrier.

While strollers and carriers are generally safe when used properly, a new study is a reminder that even these devices can be dangerous, especially when parents don't use them properly.

The federal government announced plans Thursday to lift a moratorium on funding of certain controversial experiments that use human stem cells to create animal embryos that are partly human.

The National Institutes of Health is proposing a new policy to permit scientists to get federal money to make embryos, known as chimeras, under certain carefully monitored conditions.
