Study: Viagra Also Increases "Cuddle Chemical"
August 27, 2007 05:48 PM - Paul Schaefer, ENN
University of Wisconsin-Madison - A new study finds Viagra increases the release of a key reproductive hormone. Scientists found that the little blue pill may do more than get the blood pumping. Sildenafil — the generic name for Viagra — also increases release of a reproductive hormone in rats, according to a new study. The finding is the first indication of a chemical mechanism through which erectile dysfunction drugs like Viagra may have physical effects besides increasing blood flow to sexual organs, says study author Meyer Jackson, a physiology professor at the UW-Madison School of Medicine and Public Health.

Age-related Vision Loss - Genes Vs Lifestyle
August 27, 2007 10:25 AM - Harvard Public Health Review
Nature versus nurture. When it comes to health, both exert powerful influence. To what extent does a particular disease—diabetes in children, say, or cancer in the elderly—arise from genetic baggage beyond our control, and to what degree does it result from modifiable environmental and “lifestyle” choices? While most disorders result from a combination of both genetic and environmental factors, researchers say parsing out the roles of these two players is complicated business.
When is a stem cell not really a stem cell?
August 27, 2007 07:40 AM - Johns Hopkins Medical Institutions
Working with embryonic mouse brains, a team of Johns Hopkins scientists seems to have discovered an almost-too-easy way to distinguish between ï¿½trueï¿½ neural stem cells and similar, but less potent versions. Their finding, reported this week in Nature, could simplify the isolation of stem cells not only from brain but also other body tissues.
