[Funny] A referee has sent himself off in an English amateur league ma Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Early-stage Immune System Control Of HIV May Depend On Inherited Facto How well an individual's immune system controls HIV during the earliest phases of infection appears to depend on both the specific versions of key immune-system molecules called HLA Class I that have been inherited, as well as on the fragments of viral protein those molecules display to the T lymphocytes that usually destroy infected cells. Individual Differences In Sleep Structure Are Biologically Determined Sleeping pattern variability has long been attributed to differences in several non-biological factors. Now a new study has shown that these individual differences are in large part biologically determined and may even prove to be genetic in origin. A Treasure Of Green Moss: Modern Computers To Uncover Secrets Of Duke' It's ironic. The 230,000 specimens of bryophytes -- mosses and their cousins-- in the Duke Herbarium's massive collection may have evolved some 500 million years ago. But not until 21st-century computer technology will some of their secrets be revealed. Cell Phones Put to Novel Use Forget conversations and even e-mail. Japanese gadget freaks get literary with their mobile phones, reading everything from sex manuals to full-length classics on the devices, a few lines at a time. Extreme Environment Changes Fish Appearance The world of the Devils Hole pupfish is a small place. The entire species lives in one rocky pool, 20 meters long and three meters wide, in a cave entrance in Death Valley, California. But their environment is not only cramped: it also has a profound effect on the fishes' appearance, raising questions about how rare species can be protected from extinction. Gamma Rays From Thunderstorms? Duke University engineers have led the most detailed analyses of links between some lightning events and mysterious gamma ray emissions that emanate from earth's own atmosphere. Their study suggests that this gamma radiation fountains upward from starting points surprisingly low in thunderclouds. Counter-intuitively, these strong gamma outbursts also seem to precede associated lightning discharges by a split second. Stroke In Nonvascular Atrial Fibrillation: Anti-coagulants Better Than The results of this Cochrane Systematic Review showed that anti-coagulants were more successful than anti-platelet therapies at reducing stroke. They reduced the risk of a stroke in people with AF (atrial fibrillation) by about 33 percent compared with anti-platelet therapies. The anti-platelet therapies did, however, still have an effect, reducing the risk by 20 percent when compared to people who were given no treatment. How E. Coli Bacterium Generates Simplicity From Complexity In a surprise about E. coli that may offer clues about how human cells operate, the PNAS paper reports that only a handful of dominant metabolic states are found in E. coli when it is computationally "grown"in 15,580 different environments. Cough Medicine Fights Dyskinesias In Parkinson's A cough suppressant and a drug tested against schizophrenia curb dyskinesias, the involuntary movements that are disabling side effects of taking the Parkinson's disease medication levodopa, scientists found. Dextromethorphan, used in such cold and flu medications as Robitussin and Sucrets, suppresses dyskinesias in rats. BMY-14802, a drug tested in people with schizophrenia, also suppresses dyskinesias in rats, and does so more effectively than dextromethorphan, suggesting BMY-14802 might block dyskinesias in people with Parkinson's.
