Omega Centauri - the glittering giant of the southern skies
— 14:52 GMT | AstronomyOmega Centauri is one of the finest jewels of the southern hemisphere night sky, as ESO's latest stunning image beautifully illustrates. Containing millions of stars, this globular cluster is located roughly 17 000 light-years from Earth in the constellation of Centaurus…
Fruit fly research may lead to better understanding of human heart disease
— 14:52 GMT | HealthResearchers at the Burnham Institute for Medical Research (Burnham) have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function. The study, led by Rolf Bodmer, Ph.D., was published in Proceedings of National Academy of Sciences…
New medication brings hope of jet lag cure
— 14:52 GMT | HealthA team of researchers from Monash University, The Brigham and Women's Hospital (Boston), Harvard Medical School and Vanda Pharmaceuticals has found a new drug with the potential to alleviate jet lag and sleep disorders caused by shift work…
Cardiovascular disease causing increasing inequity between rich and poor
— 14:52 GMT | HealthA new paper released today by The George Institute for International Health is warning a cardiovascular disease based epidemic is gaining pace among many low- and middle-income countries (LMIC), exemplified at its worst in the world's largest populated countries - China and India…
Stanford blood scanner detects even faint indicators of cancer
— 14:52 GMT | HealthA team led by Stanford researchers has developed a prototype blood scanner that can find cancer markers in the bloodstream in early stages of the disease, potentially allowing for earlier treatment and dramatically improved chances of survival…
Mini heart attacks lessen damage from major ones
— 14:52 GMT | HealthResearchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research…
Portable CT increases chance of stroke survival and recovery
— 14:08 GMT | HealthNew research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment. Results of the study, conducted at North Shore Medical Centre (NSMC)-Salem Hospital in Salem, Mass., will be presented today at the annual meeting of the Radiological Society of North America (RSNA)…
New movement models tested at the Smithsonian in Panama
— 14:08 GMT | EnvironmentFeeling threatened? Hungry? Looking for a mate? Move! Tracking and remote sensing data are making it easier to locate organisms and find out what they are up to. However, general theories of movement are lacking. In a special feature on Movement Ecology in the journal Proceedings of the National Academy of Sciences, researchers present integrative models for movement of organisms as diverse as gut bacteria, tree seeds, ants, marine larvae and cheetahs…
Discovery of virus in lemur could shed light on AIDS
— 14:08 GMT | HealthThe genome of a squirrel-sized, saucer-eyed lemur from Madagascar may help scientists understand how HIV-like viruses coevolved with primates, according to new research from the Stanford University School of Medicine. The discovery, to be published online on 1 December in the Proceedings of the National Academy of Sciences, could provide insight into why non-human primates don't get AIDS and lead to treatments for humans…
Evidence from dirty teeth: Ancient Peruvians ate well
— 14:08 GMT | Geology and palaeontologyStarch grains preserved on human teeth reveal that ancient Peruvians ate a variety of cultivated crops including squash, beans, peanuts and the fruit of cultivated pacay trees. This finding by Dolores Piperno, staff scientist at the Smithsonian Tropical Research Institute and the National Museum of Natural History, and Tom Dillehay, professor of archaeology at Vanderbilt University, sets the date of the earliest human consumption of beans and pacay back by more than 2,000 years and indicates that New World people were committed farmers earlier than previously thought…
