How The Zebrafish Gets His Stripe
Scientists have discovered how the zebrafish (Danio rerio) develops one of its four stripes. Their findings add to the growing list of tasks carried out by an important molecule that is involved in the arrangement of everything from nerve cells to reproductive cells in the developing embryo. Wetlands Clean Water And May Control Neighborhood Flood Problems
Constructed wetlands in planned communities can aid in surface water cleanup and flood prevention, according to Purdue University scientists who completed a five-year study on the management system. Siesta Sense: Midday Napping Associated With Reduced Risk Of Heart-rel
Among Greek adults, taking regular midday naps is associated with reduced risk of death from heart disease over a six-year period, especially among working men, according to a report in the February 12 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Conversational 'Black Holes' Reveal Uncertainty In Offices
The tension created between the supposed egalitarianism and the hierarchical realities of the American workplace can often cause conversational "black holes"during which employees avoid calling their bosses by any name, according to a Penn State researcher. Astronomers Find Part Of Universe's Missing Matter
Scientists have located a sizeable chunk of the universe that seemed to be missing since back when the stars first formed. It's floating in super-hot rivers of gas, invisible to the naked eye, surrounding galaxies like our own. And a completely different kind of mystery matter -- dark matter -- may have put it there. New Shoulder Pain Treatment Is Effective, Study Suggests
Inflammation of a tendon triggered by calcium deposits, or calcific tendinitis, can effectively be treated with a simple and cost effective percutaneous method according to a recent study. Acupuncture Relieves Pain And Improves Function In Knee Osteoarthritis
Acupuncture provides pain relief and improves function for people with osteoarthritis of the knee and serves as an effective complement to standard care. This landmark study was funded by the National Center for Complementary and Alternative Medicine (NCCAM) and the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), both components of the National Institutes of Health. Sandia Completes Depleted Uranium Study; Serious Health Risks Not Foun
Sandia National Laboratories has completed a two-year study of the potential health effects associated with accidental exposure to depleted uranium (DU) during the 1991 Gulf War. The study concluded that the reports of serious health risks from DU exposure are not supported by veteran medical statistics. Translating Form Into Function
In the last 40 years, scientists have perfected ways to determine the knot-like structure of enzymes, but they've been stumped trying to translate the structure into an understanding of function -- what the enzyme actually does in the body. This puzzle has hurt drug discovery, since many of the most successful drugs work by blocking enzyme action. Now researchers show that a solution to the puzzle is finally in sight. Melanoma Risk Only Partially Associated Vith Exposure To UVB From Sunl
Researchers at The University of Texas M. D. Anderson Cancer Center have found that the risk of developing melanoma, the most deadly form of skin cancer, is only partially associated with exposure to ultraviolet B (UVB) radiation, the rays in sunlight that increase in summer and cause sunburn.
