UCLA researchers have found a link between Parkinson's disease and the pesticide Benomyl, whose toxicological effects still linger in the environment, ten years after it was banned by the EPA. More important, the research suggests the way this pesticide does its damage may occur in other people with Parkinson's, even for those who were not exposed to this pesticide.
Researchers at UCLA say it's not just what you eat that makes those pants tighter — it's also genetics. In a new study, scientists discovered that body-fat responses to a typical fast-food diet are determined in large part by genetic factors, and they have identified several genes they say may control those responses.
The Annual Report to the Nation on the Status of Cancer, 1975–2009, shows that overall cancer death rates continued to decline in the United States among both men and women, among all major racial and ethnic groups, and for all of the most common cancer sites, including lung, colon and rectum, female breast, and prostate. However, the report also shows that death rates continued to increase during the latest time period (2000 through 2009) for melanoma of the skin (among men only) and for cancers of the liver, pancreas, and uterus. The special feature section on human papillomavirus (HPV)-associated cancers shows that incidence rates are increasing for HPV-associated oropharyngeal and anal cancers and that vaccination coverage levels in the U.S. during 2008 and 2010 remained low among adolescent girls.

The giant black hole at the center of the Milky Way may be vaporizing and devouring asteroids, which could explain the frequent flares observed, according to astronomers using data from NASA's Chandra X-ray Observatory.
Why do we like fatty foods so much? We can blame our taste buds. In the first study to identify a human receptor that can taste fat, researchers at Washington University School of Medicine in St. Louis report that our tongues recognize and have an affinity for fat and that variations in a gene can make people more or less sensitive to the taste of fat in foods.
NASA's Hubble Space Telescope has looked deep into the distant universe and detected the feeble glow of a star that exploded more than 9 billion years ago. The sighting is the first finding of an ambitious survey that will help astronomers place better constraints on the nature of dark energy: the mysterious repulsive force that is causing the universe to fly apart ever faster.
Large national study shows difference between lung function of cigarette and marijuana smokers; doctors warn against other known complications.
