New research gives a clearer understanding of how so-called "good cholesterol" helps prevent heart disease and may one day lead to treatments, according to Canadian chemists. The scientists say they have determined that a particular enzyme bound to the "good" high-density lipoprotein, or HDL, acts as a powerful antioxidant within blood vessels.

Do Environmental Pollutants Make Cancers More Aggressive?

Researchers at the Medical College of Wisconsin have identified several genes that are more active in fast-spreading prostate cancer cells than they are in less aggressive, slower-growing tumors. Drs. Paul Lindholm and Andre Balla also found that some of these aggressive genes are "turned on" by environmental pollutants.
