Clinical Guidelines Help Identify Which Children At Risk Of Bacterial A set of guidelines have been developed that can help predict the risk of bacterial meningitis for children with cerebrospinal fluid pleocytosis (presence of greater number of white blood cells than normal), reducing unnecessary hospitalizations and antibiotics, according to a study in the Jan. 3 issue of JAMA. Pitt Researchers See Electron Waves In Motion For First Time When light shines on nanosized metal particles, it excites the electromagnetic fields on the metal's surface, known as "surface plasmons,"and causes its electrons to oscillate in waves. Now, Pitt researchers have demonstrated a microscopy technique that allows the movement of the plasmons to be seen for the first time, at a resolution a trillion times better than conventional techniques. MustStream TV: The Burg An internet sitcom bridges the gap between professional production and viral distribution. By Jeff Howe from Wired magazine. Seasonal Depression Awareness Month: December The shorter days and decreased light of winter can trigger "symptoms of depression, known as Seasonal Affective Disorder (SAD)."This page explains the symptoms of and treatment options for SAD, and offers links to information on related mental health topics. From the National Mental Health Information Center of the Substance Abuse and Mental Health Services Administration (SAMHSA), U.S. Department of Health and Human Services. Gut Check: Microbes Colonize Newborns'Digestive Tracts By applying sophisticated genetic analysis to samples of a year's worth baby poop, researchers have developed a detailed picture of how an astonishing number of bacteria come and go in the intestinal tract during a child's first year of life. Liftoff! Discovery Returns Shuttle To Flight The Shuttle Discovery and its seven crewmembers are now in orbit after cruising through key flight milestones. On mission STS-114, the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. Calif. Stem-Cell Group Wins Suit An appeals court upholds the state's $3 billion stem-cell research effort. The California Institute for Regenerative Medicine will distribute $80 million in grants this month. In Bodyhack. High Blood Sugar Levels A Risk Factor For Heart Disease An elevated blood glucose level is the defining feature of diabetes, but until now it was unclear whether elevated glucose levels contributed independently to increasing heart-disease risk. Lowering blood sugar levels could reduce the risk of coronary heart disease in both diabetics and non-diabetics, according to researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. Tightly Packed Molecules Lend Unexpected Strength To Nanothin Sheet Of Scientists have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness. "It's an amazing little marvel,"said one of the researchers. "This is not a very fragile layer, but rather a robust, resilient membrane."Even when suspended over a tiny hole and poked with an ultrafine tip, the membrane boasts the equivalent strength of an ultrathin sheet of plexiglass that maintains its structural integrity at relatively high temperatures. Vegetables, Not Fruit, Help Fight Memory Problems In Old Age Eating vegetables, not fruit, helps slow downthe rate of cognitive change in older adults, according to a study published in the Oct. 24, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology
