Going Viral to Kill Zits: UCLA/Pitt Scientists Uncover Virus with Potential to Stop Pimples

Watch out, acne. Doctors soon may have a new weapon against zits: a harmless virus living on our skin that naturally seeks out and kills the bacteria that cause pimples.

The new findings by scientists at UCLA and the University of Pittsburgh are published in the Sept. 25 online edition of the American Society for Microbiology’s journal mBio. (more…)

Why Coffee Protects Against Diabetes

*Researchers discover molecular mechanism behind drink’s prophylactic effect*

Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.

Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body’s sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG.  (more…)

Does Sex Matter? It May When Evaluating Mental Status

Schizophrenia is a mental disorder that differs between the sexes in terms of age at onset, symptomatology, response to medication, and structural brain abnormalities. Now, a new study from the Université de Montréal shows that there is gender difference between men and women’s mental ability – with women performing better than men. These findings, published recently in, Schizophrenia Research, have implications for the more than 300 000 affected Canadians. 

“We are the first to report sex differences in brain function of schizophrenics,” says Université de Montréal professor, Adrianna Mendrek a researcher at the Centre de Recherche Fernand-Seguin, Hospital Louis-H Lafontaine. “We chose to study a task involving mental rotation of a three dimensional image because in healthy men and women, this consistently elicits differences in terms of reaction time and performance accuracy.”  (more…)
