Police wnt u to fight crime w/txt msgs (AP) -- Police in the 1970s urged citizens to "drop a dime" in a pay phone to report crimes anonymously. Now in an increasing number of cities, tipsters are being invited to use their thumbs - to identify criminals using text messages. Gene directs stem cells to build the heart Researchers have shown that they can put mouse embryonic stem cells to work building the heart, potentially moving medical science a significant step closer to a new generation of heart disease treatments that use human stem cells. Simple insulation could combat heat, cold and noise Around the world, an estimated one billion people--mostly in rural villages and the shanty towns surrounding developing-world cities--live in houses whose roofs are nothing more than thin sheets of corrugated metal. These houses become unbearably hot in the summer, freezing in the winter (especially in high-altitude regions), and deafeningly noisy when heavy rains pound on the bare metal. New Nanowire-Based Memory Could Beef Up Information Storage Researchers from the University of Pennsylvania have created a type of nanowire-based information storage device that is capable of storing three bit values rather than the usual two—that is, "0," "1," and "2" instead of just "0" and "1." This ability could lead to a new generation of high-capacity information storage for electronic devices. The benefits of green tea in reducing an important risk factor for heart disease More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study reported in the latest issue of European Journal of Cardiovascular Prevention and Rehabilitation. The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis. 'Multi-target' immune therapy improves outcomes of severe lupus nephritis A new treatment using a combination of drugs targeting different parts of the immune system improves the recovery rate for patients with severe lupus involving the kidneys, according to a report in the October Journal of the American Society of Nephrology (JASN). Study says cut to junior doctors' hours does not compromise patients' safety Research led by a team at the University of Warwick's Warwick Medical School has found that reducing the hours of junior doctors does not compromise patients' safety and could even dramatically cut mistakes on wards but, there are some concerns about reduced educational opportunities for junior doctors which it affords. Stanford researchers find way to predict IVF success Researchers at the Stanford University School of Medicine have identified a method that can predict with 70 percent accuracy whether a woman undergoing in vitro fertilization treatment will become pregnant. This information may someday help the tens of thousands of couples who want to undergo IVF each year, and their doctors, decide on their course of action. Once a shy monkey, always a shy monkey? New study shows persistence of anxiety We all know people who are tense and nervous and can't relax. They may have been wired differently since childhood. Penn animal study identifies new DNA weapon against avian flu Researchers at the University of Pennsylvania School of Medicine have identified a potential new way to vaccinate against avian flu. By delivering vaccine via DNA constructed to build antigens against flu, along with a minute electric pulse, researchers have immunized experimental animals against various strains of the virus. This approach could allow for the build up of vaccine reserves that could be easily and effectively dispensed in case of an epidemic. This study was published last week in PLoS ONE. ... |
