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.

Gut Bacteria We Pick Up As Kids Stick With Us For Decades

Streptococcus bacteria, like this strain, can be found in our guts.

Most of the microbes in our guts appear to remain stable for years, perhaps even most of our lives, researchers reported Thursday.

Scientists Grow A Simple, Human Liver In A Petri Dish

"Liver buds" grow in petri dishes. The rudimentary organs are about 5 mm wide, or half the height of a classic Lego block.

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.

Proposed Changes In Organ Donation Stir Debate

Hospitals and organ banks could get more leeway in decisions about donations.

The nation's organ transplant network will consider a controversial proposal Monday to overhaul the guidelines for an increasingly common form of organ donation.

The board of directors of the United Network for Organ Sharing will open a two-day meeting at the organization's headquarters in Richmond, Va., to consider new guidelines for donation after cardiac death.

Donation after cardiac death involves removing organs minutes after life-support has been stopped for patients who still have at least some brain activity.

FDA Backs Off On Regulation Of Fecal Transplants

Bad bug: The bacterium Clostridium difficile kills 14,000 people in the United States each year.

Federal regulators are dropping plans to tightly control a procedure that is becoming increasingly popular for treating people stricken by life-threatening infections of the digestive system.

The Food and Drug Administration says the agency will exercise enforcement discretion and no longer require doctors to get the agency's approval before using "fecal microbiota for transplantation."

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.

Originally published on Thu May 30, 2013 4:41 pm

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.

Research Reveals Yeasty Beasts Living On Our Skin

Fungi (cyan) surround a human hair within the skin. A study in the journal Nature shows the population of fungi on human skin is more diverse that previously thought.

Originally published on Fri May 24, 2013 11:20 am

Scientists have completed an unusual survey: a census of the fungi that inhabit different places on our skin. It's part of a big scientific push to better understand the microbes that live in and on our bodies.

"This is the first study of our fungi, which are yeast and other molds that live on the human body," says Julie Segre, of the National Human Genome Research Institute, who led the survey.

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.

Parents' Saliva On Pacifiers Could Ward Off Baby's Allergies

Sucking may be one of the most beneficial ways to clean a baby's dirty pacifier, a study found

That word "microbiome" — describing the collection of bacteria that live in and on our bodies — keeps popping up. This time, researchers say that children whose parents clean their pacifiers by sucking them might be less likely to develop allergic conditions because of how their parents' saliva changes their microbiomes.

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.
National Institutes of Health

Originally published on Mon September 9, 2013 10:38 am

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.

How Much Does It Hurt? Let's Scan Your Brain

A technique for imaging the brain allowed researchers to distinguish between physical and emotional pain.

Originally published on Thu April 11, 2013 3:16 pm

Scientists reported Wednesday that they had developed a way to measure how much pain people are experiencing by scanning their brains.

The researchers hope the technique will help doctors treat pain better, but the work is also raising concerns about whether the technique might interfere with doctors simply listening to their patients.

Now, when someone is in pain, a doctor has no way to judge its severity except to ask questions, a method that often is inadequate.
