| Posted: 21 Aug 2013 02:56 PM PDT A NASA spacecraft that discovered and characterized tens of thousands of asteroids throughout the solar system before being placed in hibernation will return to service for three more years starting in September, assisting the agency in its effort to identify the population of potentially hazardous near-Earth objects, as well as those suitable for asteroid exploration missions. |
| Rising mountains, cooling oceans prompted spread of invasive species 450 million years ago Posted: 21 Aug 2013 02:01 PM PDT New research suggests that the rise of an early phase of the Appalachian Mountains and cooling oceans allowed invasive species to upset the North American ecosystem 450 million years ago. |
| Antipsychotic drug use in children for mood/behavior disorders increases type 2 diabetes risk Posted: 21 Aug 2013 02:01 PM PDT Prescribing of "atypical" antipsychotic medications to children and young adults with behavioral problems or mood disorders may put them at unnecessary risk for type 2 diabetes, a new study shows. Young people using medications like risperidone, quetiapine, aripiprazol and olanzapine led to a threefold increased risk of developing type 2 diabetes within the first year of taking the drug, according to the study. |
| Disease caused by repeat brain trauma in athletes may affect memory, mood, behavior Posted: 21 Aug 2013 02:01 PM PDT New research suggests that chronic traumatic encephalopathy (CTE), a brain disease associated with repeat brain trauma including concussions in athletes, may affect people in two major ways: initially affecting behavior or mood or initially affecting memory and thinking abilities. The condition has been found in amateur and professional athletes, members of the military and others who experienced repeated head injuries, including concussions and subconcussive trauma. |
| After a fire, before a flood: NASA's Landsat directs restoration to at-risk areas Posted: 21 Aug 2013 12:28 PM PDT While the 138,000-acre Silver Fire still smoldered, forest restoration specialists were on the job. They analyzed maps created using Landsat satellite data to determine where the burn destroyed vegetation and exposed soil -- and where to focus emergency restoration efforts. |

| What is your heart attack risk? Posted: 21 Aug 2013 12:21 PM PDT Researchers in India have carried out a data mining exercise to determine which are the most important risk factors in increasing the chances of an individual suffering a heart attack. They confirm that the usual suspects high blood cholesterol, intake of alcohol and passive smoking play the most crucial role in "severe," "moderate" and "mild" cardiac risks, respectively. |
| Lab-made complexes are 'sun sponges' Posted: 21 Aug 2013 12:21 PM PDT Scientists have described a testbed for light-harvesting antennae, the structures that capture the sun's light in plants and bacteria. Prototype designs built on the testbed soak up more of the sun's spectrum and are far easier to assemble than synthetic antennas made entirely from scratch. They offer the best of both worlds, combining human synthetic ingenuity with the repertoire of robust chemical machinery selected by evolution. |
| Posted: 21 Aug 2013 12:21 PM PDT New results about the oscillation of neutrinos -- elusive, ghostlike particles that carry invaluable clues about the makeup of the early universe -- have been announced by the Daya Bay Collaboration, an international experiment taking place outside of Hong Kong. |
| How women achieve a healthier weight may impact long-term health of offspring Posted: 21 Aug 2013 12:21 PM PDT New research suggests that the healthy weight and glucose control women achieve through weight-loss surgery don't necessarily translate into health benefits for their future children. |
| Experimental Ebola treatment protects some primates even after disease symptoms appear Posted: 21 Aug 2013 12:20 PM PDT Scientists have successfully treated the deadly Ebola virus in infected animals following onset of disease symptoms, according to a new article. The results show promise for developing therapies against the virus, which causes hemorrhagic fever with human case fatality rates as high as 90 percent. |
| Mood is influenced by immune cells called to the brain in response to stress Posted: 21 Aug 2013 12:16 PM PDT New research shows that in a dynamic mind-body interaction during the interpretation of prolonged stress, cells from the immune system are recruited to the brain and promote symptoms of anxiety. |
| Tuberculosis genomes portray secrets of pathogen's success Posted: 21 Aug 2013 12:15 PM PDT By any measure, tuberculosis (TB) is a wildly successful pathogen. It infects as many as two billion people in every corner of the world, with a new infection of a human host estimated to occur every second. |
| Mars rover Opportunity working at edge of 'Solander' Posted: 21 Aug 2013 12:10 PM PDT NASA's Mars rover Opportunity is studying the area of contact between a rock layer formed in acidic wet conditions long ago and an even older one that may be from a more neutral wet environment. |
| NASA Voyager statement about competing models to explain recent spacecraft data Posted: 21 Aug 2013 12:06 PM PDT A newly published paper argues that NASA's Voyager 1 spacecraft has already entered interstellar space. The model described in the paper is new and different from other models used so far to explain the data the spacecraft has been sending back from more than 11 billion miles (18 billion kilometers) away from our sun. |
| Radar images of Asteroid 2005 WK4 Posted: 21 Aug 2013 12:01 PM PDT A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on Aug. 8, 2013. The asteroid is between 660 and 980 feet (200 and 300 meters) in diameter; it has a rounded and slightly asymmetric shape. As it rotates, a number of features are evident that suggest the presence of some flat regions and a bulge near the equator. |
| Genesis and evolution of H7N9 influenza virus Posted: 21 Aug 2013 10:27 AM PDT Influenza researchers have used genetic sequencing to trace the source and evolution of the avian H7N9 influenza virus that emerged in humans in China earlier this year. |
| Putting sleep disorders to bed: New way to improve internal clock function Posted: 21 Aug 2013 10:27 AM PDT Researchers have identified how a fundamental biological process called protein synthesis is controlled within the body's circadian clock -- the internal mechanism that controls one's daily rhythms. Their findings may help shed light on future treatments for disorders triggered by circadian clock dysfunction, including jet lag, shift work disorders, and chronic conditions like depression and Parkinson's disease. |
| The bitter and the sweet: Fruit flies reveal a new interaction between the two Posted: 21 Aug 2013 10:27 AM PDT Fruit flies have a lot to teach us about the complexity of food. Like these tiny little creatures, most animals are attracted to sugar but are deterred from eating it when bitter compounds are added. |
| MERS virus discovered in bat near site of outbreak in Saudi Arabia Posted: 21 Aug 2013 10:27 AM PDT A 100 percent genetic match for Middle East Respiratory Syndrome has been discovered in an insect-eating bat in close proximity to the first known case of the disease in Saudi Arabia.

Their results could potentially redefine what future lightsources ought to look like. |
| Mother's genes can impact aging process Posted: 21 Aug 2013 10:27 AM PDT Researchers have shown that aging is determined not only by the accumulation of changes during our lifetime, but also by the genes we acquire from our mothers. |
| Bacteria make us feel pain… and suppress our immune response Posted: 21 Aug 2013 10:27 AM PDT Researchers found pain from invasive skin infections from Staph, and possibly other serious, painful infections, appear to be induced by the invading bacteria themselves, and not by the body's immune response as previously thought. The research demonstrates that once the pain neurons "sense" the bacteria, they suppress the immune system, potentially helping the bacteria become more virulent. |
| Schizophrenia symptoms linked to faulty 'switch' in brain Posted: 21 Aug 2013 10:24 AM PDT Scientists have shown that psychotic symptoms experienced by people with schizophrenia could be caused by a faulty 'switch' within the brain. |
| A brighter method for measuring the surface gravity of distant stars Posted: 21 Aug 2013 10:23 AM PDT Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals its surface gravity, one of the key properties that astronomers use to calculate a star's physical properties and assess its evolutionary state. |
| Physicists pinpoint key property of material that both conducts and insulates Posted: 21 Aug 2013 10:23 AM PDT Scientists have made the first-ever accurate determination of a solid-state triple point -- the temperature and pressure at which three different solid phases can coexist stably -- in a substance called vanadium dioxide. |
