To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstra
A team of scientists at The Scripps Research Institute and the University of Wisconsin have demonstrated a new way of fighting antibiotic resistance: by stopping evolution. Secrets Of The Whale Riders: Crablike 'Whale Lice' Show How Endangered
University of Utah biologists studied the genetics of "whale lice"-- small crustaceans that are parasites on endangered "right whales"-- and showed the giant whales split into three species 5 million to 6 million years ago, and that all three species probably were equally abundant before whaling reduced their numbers. HIV Confirmatory Test Can Also Estimate Recent Infections
A test commonly used to confirm HIV infection can also be used to calculate how many recent infections have occurred in a population, according to a new study. Diagnosing recent HIV infection usually involves special testing to detect antibodies produced early on in the course of infection. The researchers showed that analyzing data already available from an antibody test routinely used to confirm HIV infection in Switzerland can accurately estimate the proportion of people who became infected within the previous 12 months. Hormone Therapy Does Not Improve Quality Of Life For Women, Finnish Tr
A postmenopausal hormone therapy trial conducted in Estonia indicates that hormone therapy does not improve women's quality of life. The group receiving hormones and the comparison group showed no differences in general quality of life. Only those women that experienced hot flashes and night-time sweating reported beneficial effects. Number Of Tropical Storms In Recent Past Increasing
Counting tropical storms that occurred before the advent of aircraft and satellites relies on ships logs and hurricane landfalls, making many believe that the numbers of historic tropical storms in the Atlantic are seriously undercounted. However, a statistical model based on the climate factors that influence Atlantic tropical storm activity shows that the estimates currently used are only slightly below modeled numbers and indicate that the numbers of tropical storms in the recent past are increasing, according to researchers. Talk Therapy More Effective Long Term Treatment For SAD Than Light The
A study by a University of Vermont psychology professor shows that cognitive behavioral therapy is more effective in the long term than light therapy in combating Seasonal Affective Disorder (SAD). CBT shows patients how learned behaviors and ingrained negative thought patterns contribute to their symptoms. Sitting inactively in front of a light box for 1-2 hours a day, the study's author says, is not only impractical, it may actually contribute to the problem. SAD season typically begins around October 30th. Secondhand Smoke Increases High School Test Failure, Study Suggests
Teens exposed to secondhand smoke at home are at increased risk of test failure in school, suggests a new study. Taking other known risk factors into account ?for example, socioeconomic status, gender, prenatal exposure to smoking and active smoking during adolescence ?researchers found that exposure to secondhand smoke at home decreased the odds of passing standardized achievement tests by 30 percent in 16- and 18-year-olds. 'Cosmic Freezer' Yields Unique Discovery
Stardust, the NASA spacecraft mission, was given that name in hopes that the seven-year journey to capture comet samples would bring back to Earth, well, stardust. In an article coming out in the December 15, 2006, issue of the journal Science, researchers at Washington University in St. Louis are the first to report that a sample they received from the mission actually does contain stardust -- particles that are older than the sun. Preventing Alzheimer's Disease Early On
People with Alzheimer's disease and related conditions have been found to exhibit decreased blood levels of an important brain chemical called ethanolamine plasmalogen, even at the very early stages of the disease. The scientists also discovered that this decrease is more pronounced when the symptoms are more severe. Serving Up Suds A Hazardous Task
A joint study published in the September edition of Applied Ergonomics by the University of Alberta and Napier University of Scotland, shows that servers, cooks and bartenders risk serious injuries while doing their everyday jobs serving up suds and finger foods.
