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.

Police in California made headlines this spring when they charged a former police officer with being the Golden State Killer, a man who allegedly committed a series of notorious rapes and murders in the 1970s and '80s.

Authorities revealed they used DNA from a publicly available genealogy website to crack the case.

A large study has produced strong evidence that a drug commonly used to treat the bone-thinning disease osteoporosis could safely prevent fractures in elderly women who have bones that aren't as weak.

For the first time, scientists have demonstrated that a controversial new kind of genetic engineering can rapidly spread a self-destructive genetic modification through a complex species.

Scientists say they have taken a potentially important — and possibly controversial — step toward creating human eggs in a lab dish.

A team of Japanese scientists turned human blood cells into stem cells, which they then transformed into very immature human eggs.

The eggs are far too immature to be fertilized or make a baby. And much more research would be needed to create eggs that could be useful — and safe — for human reproduction.

Many healthy Americans take a baby aspirin every day to reduce their risk of having a heart attack, getting cancer and even possibly dementia. But is it really a good idea?

Results released Sunday from a major study of low-dose aspirin contain a disappointing answer for older, otherwise healthy people.

It's early in the morning and 20-year-old Aaron Reid looks like he's sleepwalking.

His head nods forward and he shuffles a bit as he heads toward the pediatric clinic at the National Institutes of Health Clinical Center.

Reid, who has been fighting leukemia since he was 9-years old, is experiencing intense pain.

He can't say much at the moment, so his mother, Tracie Glascox, speaks for him. "He's been complaining of pain in his ankles, his knees and his arms," she tells the nurse.

The Food and Drug Administration announced a set of major new enforcement actions Wednesday aimed at reducing the sales and marketing of electronic cigarettes to teenagers.

Saying vaping among teenagers has reached "an epidemic proportion," the agency said it was taking a "series of critical and historic" measures to curb the alarming trends.

Aaron Reid is lying in a hospital bed at the National Institutes of Health Clinical Center when doctors arrive to make sure he's ready for his experimental treatment.

"How's your night? Any issues?" asks Dr. Katherine Barnett, a pediatric oncologist, as they begin to examine Reid.

Reid, 20, of Lucedale, Miss., has been fighting leukemia since he was 9 years old. He has been through chemotherapy and radiation twice, a bone marrow transplant and two other treatments.

Since Zika emerged as a threat to babies, it has been a mystery exactly how much of a danger the mosquito-borne virus poses to children.

But now, the largest study to follow kids who were exposed to the virus in the womb is providing more answers.

The study involved 1,450 babies who had been exposed to the virus, and who were 1-year-old by February 2018. Six percent were born with birth defects, and 14 percent developed problems that could be blamed on the virus by the time they turned 1, the study found.

Scientists on the hunt for anti-aging drugs say they've made an advance with tantalizing potential: Two experimental drugs appear to safely boost the immune systems of elderly humans.

The researchers stress that more research is needed to confirm the findings and show the drugs are safe. And at least one researcher says the findings are based on a relatively small number of people and used methods that could produce misleading results.

Still, many researchers say the findings are encouraging.
