Game|Life Survivor Begins Three applicants survive in our quest for a new blogger (after we weeded out 4,499,850 e-mails from Nigerian bank scammers). Stay tuned to see who gets to stay in Game|Life and who is voted off the island. In Game|Life. [Ironic] Professional beggars prowling about the streets of Moroccan c The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Brain Implants Relieve Alzheimer's Damage Genetically engineered cells implanted in mice have cleared away toxic plaques associated with Alzheimer's disease. The animals were sickened with a human gene that caused them to develop, at an accelerated rate, the disease that robs millions of elderly people of their memories. After receiving the doctored cells, the brain-muddling plaques melted away. If this works in humans, old age could be a much happier time of life. Confined Electrons Live Longer Electrons that are trapped in very small structures of only a few nanometer, demonstrate fascinating features. These could be useful for novel computers or semiconductor lasers. Researchers have measured for the first time the exact lifetime of excited electrons. Antibiotic Resistance Genes As Emerging Environmental Pollutants Antibiotic resistance genes (ARGs) should be considered emerging environmental contaminants with more research devoted to the mechanisms by which they spread, scientists say in a report scheduled for the Dec. 1 issue of the semi-monthly ACS journal Environmental Science &Technology. Cold Treatment Kills Fruit Fly On Citrus Fruits Cold storage at temperatures of 2°or 3°C can effectively kill Queensland Fruit Fly in citrus stored for 14 to 16 days. This method provides an alternative to methyl bromide fumigation, which is toxic to citrus and shortens its shelf life. Methyl bromide is also being phased out in Australia because it is ozone depleting, according to researchers. Muscle Repair: Making A Good System Better, Faster; Implications For A Skeletal muscles naturally repair themselves very efficiently but researchers at the Universities of Illinois-Chicago and Michigan found that a deficiency in plasminogen activator inhibitor-1 (PAI-1) actually promotes muscle regeneration, making PAI-1 "a therapeutic target for enhancing muscle regeneration."The plasminogen system's interaction with inflammatory, growth factor and other systems is more complicated than thought, indicating the plasminogen system likely may have multiple functions, with implications for aging, liver, lungs, heart, and degenerative diseases like muscular dystrophy. Winter, Nighttime Tornadoes Pose Greatest Risk, National Weather Servi Shrouded in darkness, nighttime tornadoes can be deadly, especially during the winter season when people are not accustomed to such severe weather. Given the dangers, forecasters with NOAA's National Weather Service are increasing efforts to alert people of a potential threat in their area before they go to sleep. Earth's Core Rotates Faster Than Its Crust, Scientists Say Scientists have ended a 9-year-old debate by proving that Earth's core rotates faster than its surface, by about 0.3 to 0.5 degree per year. Earth's iron core consists of a solid inner core about 2,400 kilometers in diameter and a fluid outer core about 7,000 kilometers in diameter. The inner core plays an important role in the geodynamo that generates Earth's magnetic field, and an electromagnetic torque from the geodynamo is thought to drive the inner core to rotate relative to the mantle and crust. Hubble Finds Mysterious Disk Of Blue Stars Around A Black Hole Astronomers using the NASA/ESA Hubble Space Telescope have identified the source of a mysterious blue light surrounding a supermassive black hole in our neighbouring Andromeda Galaxy (M31). Though the light has puzzled astronomers for more than a decade, the new discovery makes the story even more mysterious.
