Use Of Non-Steroidal Anti-Inflammatory Drugs Suspended In Large Alzhei
The National Institutes of Health (NIH) announced that research investigators suspended, until further notice, the use of two drugs, naproxen (220 mg twice a day) and celecoxib (200 mg twice a day), in a large, three-arm, national Alzheimer's disease prevention trial sponsored by the National Institute on Aging (NIA), a part of the NIH. New Study Of Tree Roots Will Alter Carbon-sequestration Models
Using a new carbon tracing method, Argonne ecologists and their colleagues have determined that life spans of fine tree roots are much longer than expected and differ according to the species. The fine roots of pine trees last four to six years, while sweetgum roots have shorter life spans of 1.3 to three years. Rhythm Gene Discovered: The Scoop On When Worms Poop, Ovulate And Swal
University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping. The same of related genes may control rhythmic behaviors in humans and other animals.
Museum of Domestic Design &Architecture (MoDA)
This interior design museum, part of Middlesex University in Britain, offers exhibitions that "give a vivid picture of domestic life in the first half of the twentieth century while also looking at contemporary design, art and issues related to the domestic environment."The site features a description and online catalog of the collection (use the "light box"to access records with selected images), information about exhibits, online teaching resources, and links to related sites. High School Theater Program Helped Strengthen Adolescents'Emotional De
A unique study found that adolescents'emotional skills were strengthened through a high school theater program. The study, conducted among adolescents in a high school theater program, demonstrated how teens learned about how to employ positive emotions to motivate their work. Students also used strategies to manage their own and others'negative emotions. The research was conducted through interviews with the students during a three-month period of rehearsals. This study demonstrates how schools and programs can support the development of "emotional intelligence"of adolescents. Galaxy Collisions Dominate The Local Universe
More than half of the largest galaxies in the nearby universe have collided and merged with another galaxy in the past two billion years, according to a Yale astronomer in a study using hundreds of images from two of the deepest sky surveys ever conducted. Therapeutics for trauma patients may not be effective if infection is
A new study is analyzing how the immune system is involved in damage to the intestines following hemorrhagic shock. While studying the effects of a complement inhibitor given following hemorrhage, it found that Helicobacter infection changes the body's mechanistic response and would therefore affect the therapeutics given to trauma patients. Water Filter Could Help Millions
Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Ashok Gadgil is developing a cheap and effective way to provide safe drinking water to 60 million Bangladeshis who live under the specter of arsenic poisoning. His idea is to create arsenic filters from coal ash, the fine gray powder that piles up at the bottom of furnaces at all coal-fired power stations, waiting to be discarded. Lung Cancer Risk Increases With Expression Of Specific Genes
A recent study determined that variations of specific genetic markers identified in previous research, or SNPs, may indicate a greater lung cancer risk in African Americans than in whites. The genes CHRNA3 and CHRNA5 may contribute to lung cancer risk due directly or through their association with nicotine dependence. Although their presence is less frequent in African-Americans, the risk for lung cancer may be greater when present. Nanotechnology Meets Biology And DNA Finds Its Groove
The object of fascination for most is the DNA molecule. But in solution, DNA, the genetic material that hold the detailed instructions for virtually all life, is a twisted knot, looking more like a battered ball of yarn than the famous double helix. To study it,scientists generally are forced to work with collections of molecules floating in solution, and there is no easy way to precisely single out individual molecules for study.
