Getting On Your Nerves ... And Repairing Them
In a study to be published in the March 2007 issue of the FASEB Journal, scientists from East Carolina University report that a key molecular mechanism, RNA interference (RNAi), plays a role in the regeneration and repair of periphery nerves, which are the nerves located outside of the brain and spinal column. This research may lead to new therapies that manipulate RNAi to treat people with damaged nerves resulting from degenerative disorders and injury. Portable High-Resolution NMR Sensor Unveiled At Berkeley
Homeland security experts may soon be getting a valuable new tool for identifying the chemical constituents in suspicious substances. A portable device makes it possible for the first time ever to take high-resolution NMR spectroscopy -- one of the principal tools for chemical analysis -- out of the laboratory and into the field for use on samples of any size. DIY Nuke Detector Patrols SF Bay
Volunteer researchers develop a mobile radiation scanner that can pick out a nuclear bomb in a containership at sea. Mark Rutherford reports from San Francisco. Indie Bookstores Tackle Internet
Book lovers, new business models and clerks who read keep independent bookstores alive in the face of online shopping and big-box bargains. Discovery Could Help In The Development Of Sensors Against Chemical Th
Single-walled carbon nanotubes (SWNTs), which could play an important role in developing sensors against chemical threats, have enhanced interaction with ammonia because of the presence of oxygen groups on the nanotubes, researchers at Temple University have discovered. Scientists Identify Genetic Pathways Essential To RNA Interference
A research team based at Massachusetts General Hospital (MGH) has identified 80 new genes essential to the process of RNA interference (RNAi), a powerful new research tool for inactivating genes in plants or animals. They used the RNAi process itself to find new genes that participate in the gene-silencing mechanism, which someday may help to fight human disease. Naturally Occurring Asbestos Linked To Lung Cancer
Everyday exposure to naturally occurring asbestos increases the risk of developing malignant mesothelioma, according to a study by UC Davis researchers. The study - the largest to examine the question - will be published this fall in the American Journal of Respiratory and Critical Care Medicine. Anthracyclines Improve Survival In HER2-positive Breast Cancer Patient
Treatment with the class of chemotherapy drugs called anthracyclines improves survival in women with HER2-positive breast cancer who have previously had surgery, but it may not offer any benefit for women with HER2-negative tumors, according to a study published online Dec. 25 in the Journal of the National Cancer Institute. August Wilson 4/27/45-10/2/05
Collection of news and analysis about playwright August Wilson, who was born and raised in Pittsburgh and who also lived in St. Paul, Minnesota, and Seattle. Features a timeline, photos, obituary, and background about his Pittsburgh cycle of 10 plays, "each situated in a different decade of the 20th century, ... [which explore] the comedy and tragedy ... of African-American history and culture."Also includes links to many related articles. From the Pittsburgh Post-Gazette. Vanderbilt Chemical Engineers Question Safety Of Certain Nanomaterials
Soccer-ball-shaped "buckyballs"are the most famous players on the nanoscale field, presenting tantalizing prospects of revolutionizing medicine and the computer industry. Since their discovery in 1985, engineers and scientists have been exploring the properties of these molecules for a wide range of applications and innovations. But could these microscopic spheres represent a potential environmental hazard?
