Even later preemies face respiratory risks

Babies born weeks before their due date are at increased risk for serious breathing problems, according to a new nationwide study.

Preemies born before the 37th week of pregnancy are at increased risk for breathing and respiratory illness because their lungs aren’t fully developed. “The pulmonary system is the last to develop last in the fetus,” explains Dr. Judith Hibbard, one of the study authors.

Hibbard, a maternal fetal specialist at the University of Illinois in Chicago, says this study shows that "we need to deliver babies as close to 39 weeks as possible."

Social relationships key to survival, study says

Having satisfying social relationships may be about as important as not smoking when it comes to your lifespan, a new study suggests.

It turns out that people with adequate social relationships have a 50 percent greater likelihood of survival than people who have poor or insufficient relationships. That means that having good relationships is comparable to quitting smoking in terms of survival benefit, and is a stronger factor than obesity and physical activity.

Music may harm your studying, study says

If you're studying for a test, putting on background music that you like may seem like a good idea. But if you're trying to memorize a list in order - facts, numbers, elements of the periodic table - the music may actually be working against you, a new study suggests.

Researchers at the University of Wales Institute in Cardiff, United Kingdom, looked at the ability to recall information in the presence of different sounds. They instructed 25 participants between ages 18 and 30 try to memorize, and later recall, a list of letters in order. The study authors are Nick Perham and Joanne Vizard, and the study will appear in the September 2010 issue of Applied Clinical Psychology.

'No scientific basis' seen for at-home DNA tests

If you've considered purchasing one of the many products allowing you to perform at-home, personalized genetics tests, a new government report says, don't waste your money.

According to an undercover investigation conducted by the U.S. Government Accountability Office, consumers may fall victim to deceptive marketing and should be wary of products claiming to create personalized supplements, cure disease, and repair damaged DNA. "There is no scientific basis for such claims," the report says.

“It's about time," says bioethicist, Art Caplan, an expert in the field. He says the research just hasn’t supported the use of the tests, and that the biggest surprise is how long it took the government to address what he calls "highly advertised genetic scamming."
