Breast Reduction May Lead To Cancer Detection In Patients Posted: 26 Oct 2009 05:00 AM PDT There may be some new added benefits to breast reduction surgery. Testing tissue and fat removed during the procedure may lead to increased cancer detection, according to a new study.

Treaty To Limit Carbon Dioxide Should Be Followed By Similar Limits On Other Greenhouse Pollutants Posted: 26 Oct 2009 05:00 AM PDT While carbon dioxide is the main greenhouse gas and the focus of climate treaties, other pollutants that stay in the atmosphere for only days or months also contribute to global warming. Researchers argue that policymakers should plan a summit now to look at these pollutants, which range from soot to ozone and methane, because they will be more complicated to regulate than is the case with carbon dioxide.

Power At Work Has Payoffs, But Not For Health Posted: 26 Oct 2009 05:00 AM PDT Being at the top has its perks, but new research shows people in positions of authority at work are more likely to experience certain psychological and physical problems that can undermine the health benefits associated with job authority.

Mantis Shrimp Eyes Could Show Way To Better DVD And CD players Posted: 26 Oct 2009 02:00 AM PDT The remarkable eyes of a marine crustacean could inspire the next generation of DVD and CD players, according to a new study.

Master Regulator Found For Regenerating Nerve Fibers In Live Animals Posted: 26 Oct 2009 02:00 AM PDT Researchers have found an essential factor for regenerating neurons in the central nervous system, which normally can't regenerate. This enzyme, or factors that stimulate it, could lead to a possible treatment for stroke, spinal cord damage and traumatic brain injury.

Sage-grouse Populations In US Intermountain West May Be Threatened By Energy Development, Study Predicts Posted: 26 Oct 2009 02:00 AM PDT A new study sheds light on oil and gas development potential in the US Intermountain West. Maps accompanying the study show the impacts to greater sage-grouse populations in relation to potential energy development. If business as usual continues and more forward-thinking development strategies are not considered, sage-grouse populations will decline an additional 7 to 19 percent, the study's authors predict.

T-Cell Vaccine Reduces Simian Immunodeficiency Virus Levels In Semen Of Monkeys During Primary Infection Posted: 26 Oct 2009 02:00 AM PDT A new study reports that a vaccine-induced cellular immune response reduced simian immunodeficiency virus (SIV) levels in the semen of rhesus monkeys during the period of primary infection, a discovery that may ultimately aid in the fight against HIV-1 transmission in humans.

Flower Garden Banks National Marine Sanctuary Among Healthiest Coral Reefs In Gulf Of Mexico Posted: 26 Oct 2009 02:00 AM PDT Flower Garden Banks National Marine Sanctuary is among the healthiest coral reef ecosystems in the tropical Caribbean and Gulf of Mexico, according to NOAA researchers. Their report offers insights into the coral and fish communities within the sanctuary based on data collected in 2006 and 2007.

Adolescents' Gambling A Part Of A Cluster Of Problem Behaviors Posted: 26 Oct 2009 02:00 AM PDT Ten percent of young adolescent boys -- or one in 10 -- exhibit a symptom of conduct disorder as well as a symptom of risky or problem gambling, according to new research findings.

First Hyperlens For Sound Waves Created Posted: 25 Oct 2009 11:00 PM PDT Researchers have developed the world's first acoustic hyperlens, a device that provides an eightfold boost in the magnification power of ultrasound, underwater sonar and other sound-based imaging technologies.
