Rob Stein is a correspondent and senior editor on NPR's science desk.

In his reporting, Stein focuses on the intersection of science, health, politics, social trends, ethics, and federal science policy. He tracks genetics, stem cells, cancer research, the obesity epidemic, and other science, medical, and health policy news.

Before NPR, Stein served as The Washington Post's science editor and national health reporter for 16 years, editing and then covering stories nationally and internationally.

Earlier in his career, Stein spent about four years at NPR's science desk. Before that, he served as a science reporter for United Press International in Boston and the science editor of the international wire service in Washington.

Stein is a graduate of the University of Massachusetts in 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.

Diverse Gut Microbes, A Trim Waistline And Health Go Together

The tale of the tape may be told, in part, by the microbes inside you.

Scientists have discovered new clues about how microbes in our digestive systems may affect health.

European researchers found that the less diverse those microbes are, the more likely people are to gain weight, become obese and develop risk factors for serious health problems.

Evidence has been mounting in recent years that bacteria and other organisms in our bodies do a lot more than just help us digest food.

Brains Of Dying Rats Yield Clues About Near-Death Experiences

Could the images common in accounts of near-death experiences be explained by a rush of electrical activity in the brain?

A burst of brain activity just after the heart stops may be the cause of so-called near-death experiences, scientists say.

The insight comes from research involving nine lab rats whose brains were analyzed as they were being euthanized. Researchers discovered what appears to be a momentary increase in electrical activity in the brain associated with consciousness.

Although the experiment relied on animals, the results could apply to humans, too, the researchers say.

Scientists Grow A Simple, Human Liver In A Petri Dish

Japanese scientists have cracked open a freaky new chapter in the sci-fi-meets-stem-cells era. A group in Yokohama reported it has grown a primitive liver in a petri dish using a person's skin cells.

The organ isn't complete. It's missing a few parts. And it will be years --maybe decades — before the technique reaches clinics.

Disinfect All ICU Patients To Reduce 'Superbug' Infections

To fight antibiotic-resistant staph germs like these, a study suggests disinfecting the skin of all intensive care patients.

Hospitals can sharply reduce the spread of the drug-resistant bacteria in their intensive care units by decontaminating all patients rather than screening them and focusing only on those found to be infected already, researchers reported Wednesday.

Scientists clone human embryos to make stem cells

Scientists say they have, for the first time, cloned human embryos capable of producing embryonic stem cells.

The accomplishment is a long-sought step toward harnessing the potential power of embryonic stem cells to treat many human diseases. But the work also raises a host of ethical concerns.

Gut Bacteria's Belch May Play A Role In Heart Disease

More than just a tenant: Enterococcus faecalis thrives in the human intestine with a varied jumble of other bacteria that help us digest food.

Scientists have discovered what may be an important new risk factor for heart disease. And here's the surprising twist: The troublesome substance seems to be a waste product left behind by bacteria in our guts as they help us digest lecithin — a substance plentiful in red meat, eggs, liver and certain other foods.

Doctors say the research further illustrates the complicated relationship we have with the microbes living inside us, and could lead to new ways to prevent heart attacks and strokes.

Researchers use brain scans to reveal hidden dreamscape

A window into dreams may now be opening.

Scientists say they have found a way to get a glimpse of people's dreams.

"Our results show that we can predict what a person's seeing during dreams," says Yukiyasu Kamitani, a researcher at the ATR Computational Neuroscience Laboratories in Kyoto, Japan.

Philosophers, poets and psychologists have long shared a fascination with dreams. But Jack Gallant, a neuroscientist at the University of California, Berkeley says solving the mystery of our dreams is one tough problem.

Can You Get A Flu Shot And Still Get The Flu?

This year's flu season started about a month early, prompting federal health officials to warn it could be one of the worst in years. They're urging everyone to get their flu shots.

But like every flu season, there are lots of reports of people complaining that they got their shot but still got the flu. What's up with that?

Well, as Michael Jhung of the Centers for Disease Control and Prevention explains, there are lots of possible reasons.

Geneticist reported Wednesday that they had crossed a threshold long considered off-limits: They have made changes in human DNA that can be passed down from one generation to the next.

The researchers at Oregon Health & Science University in Portland say they took the step to try to prevent women from giving birth to babies with genetic diseases. But the research is raising a host of ethical, social and moral questions.

Scientists create fertile eggs from mouse stem cells

Scientists in Japan report they have created eggs from stem cells in a mammal for the first time. And the researchers went on to breed healthy offspring from the eggs they created.

While the experiments involved mice, the work is being met with excitement — and questions — about doing the same thing for humans someday.
