Televised medical talk shows: Health education or entertainment?
Millions of viewers around the world watch the televised medical talk programs 'The Dr. Oz Show' and 'The Doctors' for medical advice, but how valuable are the recommendations they receive? In a first of its kind study, researchers have examined the recommendations given on those two shows to see if there is believable evidence to back up the claims presented. The results were revealing.

Polymorphism, bacteria inside us help dictate inflammation, antitumor activity
A common polymorphism can lead to a chain of events that dictates how a tumor will progress in certain types of cancer, including a form of breast cancer as well as ovarian cancer, according to new research. The research reveals a more explicit role about the symbiotic relationship humans have with the various bacteria that inhabit our body and their role during tumor progression.

First direct evidence that a mysterious phase of matter competes with high-temperature superconductivity
Scientists have found the first direct evidence that a mysterious phase of matter known as the "pseudogap" competes with high-temperature superconductivity, robbing it of electrons that otherwise might pair up to carry current through a material with 100 percent efficiency.

Early exposure to antidepressants affects adult anxiety, serotonin transmission
Early developmental exposure to two different antidepressants, Prozac and Lexapro, has been studied by researchers in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective reuptake inhibiting antidepressants were thought to work the same way, they did not produce the same long-term changes in anxiety behavior in the adult mice. About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants.

Cheaper 3-D virtual reality system: Powerful enough for a gamer, made for an engineer
It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3-D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming. On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3-D glasses worn by the user create dizzying added dimensions.

Reducing emergency surgery cuts health care costs
Researchers have determined the hospital costs and risk of death for emergency surgery and compared it to the same operation when performed in a planned, elective manner for three common surgical procedures: abdominal aortic aneurysm repair, coronary artery bypass graft and colon resection. The research indicates that reducing emergency surgery for three common procedures by 10 percent could cut $1 billion in health care costs over 10 years.

Family criticizing your weight? You might add more pounds
Women whose loved ones are critical of their weight tend to put on even more pounds, says a new study on the way people's comments affect our health. "When we feel bad about our bodies, we often turn to loved ones -- families, friends and romantic partners -- for support and advice. How they respond can have a bigger effect than we might think," said one author.
