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.

"This is a huge scientific advance," said Dr. George Daley, a Harvard stem cell scientist who wasn't involved in the work.

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

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.

That's the word from a small study of 184 Swedish babies published in this week's issue of the journal Pediatrics.

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

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.

"We all have trouble communicating our pain and other feelings under different circumstances," 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.

More than 1 million people are dying prematurely every year from air pollution in China, according to a new analysis.

"This is the highest toll in the world and it really reflects the very high levels of air pollution that exist in China today," says Robert O'Keefe of the Health Effects Institute in Boston, who presented the findings in Beijing this week.

Alarm has been growing in recent years about the air in China.

Bioethics Panel Warns Against Anthrax Vaccine Testing On Kids

A controversial government proposal to test the anthrax vaccine in children would be unethical without first conducting much more research, a presidential commission concluded Tuesday.

"The federal government would have to take multiple steps before anthrax vaccine trials with children could be ethically considered," Amy Gutmann, who chairs the Presidential Commission for the Study of Bioethical Issues, tells Shots.

Americans More Distracted Behind The Wheel Than Europeans

U.S. drivers are much more likely than Europeans to drive while distracted, federal health officials report Thursday.

Nearly 69 percent of Americans who drive say that they talked on their cell phones while driving at least once in the previous month, according to a survey by the Centers for Disease Control and Prevention.

That's a lot higher than what was reported by Europeans in another survey. Only 21 percent of British drivers reported chatting on their cell phones while behind the wheel, for example.

Infections With 'Nightmare Bacteria' Are On The Rise In U.S. Hospitals

Federal officials warned Tuesday that an especially dangerous group of superbugs has become a significant health problem in hospitals throughout the United States.

These germs, known as carbapenem-resistant Enterobacteriaceae, or CRE, have become much more common in the last decade, according to the Centers for Disease Control and Prevention. And the risk they pose to health is becoming evident.

"What's called CRE are nightmare bacteria," Dr.

Pediatricians Urged To Treat Ear Infections More Cautiously

Hoping to reduce unnecessary antibiotics use, the American Academy of Pediatrics on Monday issued new guidelines for how doctors should diagnose and treat ear infections.

Every year, millions of parents take their children to the pediatrician for ear infections, and most of them end up going home with antibiotics.
