First known binary star is discovered to be a triplet, quadruplet, quintuplet, sextuplet system (December 13, 2009) -- Alcor and Mizar, were the first binary stars -- a pair of stars that orbit each other -- ever known. Now, astronomers have made the surprise discovery that Alcor is also actually two stars, and is apparently gravitationally bound to the Mizar system, making the whole group a sextuplet. ... > full story
New model of skin cancer provides insights on second-most common type of cancer (December 13, 2009) -- Researchers have developed a new model of skin cancer based on the knowledge that a common cancer-related molecule called Src kinase is activated in human skin-cancer samples. ... > full story
New research may lead to new ways to control honeybee parasite (December 13, 2009) -- Ground-breaking discoveries could help protect honeybees from deadly parasites that have devastated commercial colonies. ... > full story
Potential new heart attack biomarker uncovered (December 13, 2009) -- Researchers have identified cardiac myosin-binding protein C as a potential new diagnostic biomarker for heart attacks, one that may be particularly valuable for mild attacks in which traditional diagnostic proteins may not be abundant enough. ... > full story
Synthetic protein mimics structure, function of metalloprotein in nature (December 13, 2009) -- Scientists have designed a synthetic protein that is both a structural model and a functional model of a native protein, nitric-oxide reductase. ... > full story
New screening tool helps identify children at risk for developmental issues (December 13, 2009) -- When a baby is born, new parents often wonder, "Will he be the next President of the United States?" or "Could she be the one to find a cure for cancer?" But the underlying question for many specialists is, "Is this child 'at risk' for developmental issues?" An answer to this question has been elusive -- until now. ... > full story
Brightest-ever 'blazar' flare from distant galaxy spotted by NASA's Fermi Gamma-ray Space Telescope (December 12, 2009) -- A galaxy located billions of light-years away is commanding the attention of NASA's Fermi Gamma-ray Space Telescope and astronomers around the globe. Thanks to a series of flares that began September 15, the galaxy is now the brightest source in the gamma-ray sky -- more than ten times brighter than it was in the summer. ... > full story
With amino acid diet, mice improve after brain injury (December 12, 2009) -- Neurology researchers have shown that feeding amino acids to brain-injured mice restores their cognitive abilities and may set the stage for the first effective treatment for cognitive impairments suffered by people with traumatic brain injuries. If these animal results can be translated to human medicine, there would be a broad clinical benefit. Every 23 seconds, a man, woman or child in the US suffers a traumatic brain injury. ... > full story

West Nile virus infection may persist in kidneys years after initial infection (December 12, 2009) -- A new study shows that people who have been infected with West Nile virus may have persistent virus in their kidneys for years after initial infection, potentially leading to kidney problems. ... > full story
Elusive 'hot' electrons captured in ultra-thin solar cells (December 12, 2009) -- Harnessing the power of "hot" electrons for solar energy has been held as a theoretical possibility. Now researchers report observing the hot electron effect in an ultra-thin solar cell for the first time and collecting the elusive charges, which are typically lost in less than one-trillionth of a second in traditional solar cells. ... > full story
Antidepressant may change personality while relieving symptoms (December 12, 2009) -- Individuals taking a medication to treat depression may experience changes in their personality separate from the alleviation of depressive symptoms, according to a new report. ... > full story
