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.

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.

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?

Biologist Ethan Bier runs a laboratory at the University of California, San Diego where fruit flies are used to help unravel the processes that lead to some human diseases. One day recently, a graduate student in the lab called him over to take a look at the results of the latest experiment.

Bier was stunned by what he saw. "It was one of the most astounding days in my personal scientific career," Bier says. "When he first showed me, I could not believe it."

A decades-long decline in the death rate of middle-aged white Americans has reversed in recent years, according to a surprising new analysis released Monday.

The cause of the reversal remains unclear. Researchers speculate it might be the result of the bad economy fueling a rise in suicides, plus overdoses from prescription painkillers and illegal drugs like heroin, and alcohol abuse.

Most women don't need to start getting an annual mammogram to screen for breast cancer until they turn 45, according to the latest guidelines from the American Cancer Society.

Previously, the society recommended women start annual mammograms at 40 and continue every year for as long they remained in good health.

Tens of thousands of Americans are treated in hospital emergency rooms each year for problems caused by dietary supplements, federal health officials are reporting.

The complications include heart problems such as irregular or rapid heartbeat or chest pain, says Dr. Andrew Geller of the federal Centers for Disease Control and Prevention, who led the study published Wednesday in the New England Journal of Medicine.
