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.

"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.

China's Air Pollution Linked To Millions Of Early Deaths

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.
