Supercomputing By Reservation Puts Petaflops At Researchers'Fingertips Supercomputers keep growing ever faster, racing along at the blazing speed of nearly one petaflops -- 10 to the fifteenth, or one thousand trillion calculations per second -- equivalent to around 250 thousand of today's laptops. In contrast, the experience of a computational scientist can be anything but fast -- waiting hours or days in a queue for a job to run and yield precious results needed for further steps. The unpredictably of queues can impede the course of research, slowing progress with unexpected periods of waiting. High Security for $100 Laptop The security guru for the One Laptop Per Child program unveils his plan to make the rugged machines uniquely resistant to spyware and hack attacks. Ryan Singel reports from the RSA Conference. Use Folic Acid To Cut Heart Disease, Say Experts The scientific evidence is strong enough to justify using folic acid as a cheap and simple way of reducing heart disease and strokes, say researchers in this week's British Medical Journal. Mothers'Second-hand Smoke Exposure Linked To Psychological Problems Fo Children whose mothers were exposed to second-hand smoke while they were pregnant have more symptoms of serious psychological problems compared to the offspring of women who had no prenatal exposure to smoke, according to a new study. Are Influenza Vaccines Worth The Effort? Each year enormous effort goes into producing influenza vaccines anddelivering them to appropriate sections of the population. But a review of the evidence in this week's British Medical Journal suggests that they may not be as effective as we think. Saturn's Moon Enceladus Is Unlikely To Harbor Life A new model of Saturn's icy moon Enceladus may quell hopes of finding life there. The model explains the most salient observations on Enceladus without requiring the presence of liquid water. Research Pinpoints West Nile Virus Antibody Binding Site Researchers have learned the precise location where an antibody binds to the West Nile virus, and they have suggested a mechanism for how this antibody neutralizes the virus to prevent infection. NASA's AcrimSat Solar Spacecraft Completes Five-Year Mission A NASA satellite that measures the variability in the amount of the Sun's energy that reaches Earth's atmosphere and impacts our winds, land and oceans has successfully accomplished its five-year primary mission. Researchers In Spain Develop New Gluten-free Bread Researchers at the Food Technology Plant Special Research Centre (CeRPTA) have for the first time developed a completely gluten-freebread that is of a much higher quality than products currently available for coeliacs. The product was 100 percent successful in the tests carried out. The resulting product has an increased nutritional value, a longer useful life and a similar texture to traditional bread. Gastroenterologists study mind-body techniques for treating celiac dis For adults and children diagnosed with celiac disease, the only treatment is a gluten-free diet, which can be very challenging. Gastroenterologists are conducting a new study to see if mind/body techniques could help patients with celiac disease adhere to the very strict diet.
