New Robotic Repair System Will Fix Ailing Satellites - Researchers are developing a new robotic system to service more than 8,000 satellites now orbiting the Earth, beyond the flight range of ground-based repair operations. Currently, when the high-flying celestial objects malfunction -- or simply run out of fuel -- they become "space junk" cluttering the cosmos.... Tumor Formation In Stem Cells Linked to Mitochondria - Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -- a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors.... Millisecond Brain Signals Predict Response To Fast-acting Antidepressant - Images of the brain's fastest signals reveal an electromagnetic marker that predicts a patient's response to a fast-acting antidepressant. Such use of a brain scanner could someday minimize trial-and-error prescribing and speed delivery of care, say researchers. Depressed patients showed increased activity in a mood-regulating hub near the front of the brain while viewing flashing frightful faces -- the more the increase, the better their response to an experimental fast-acting medication called ketamine....

H. Pylori Bacteria May Help Prevent Some Esophageal Cancers - Some bacteria may help protect against the development of a type of esophageal cancer, known as adenocarcinoma, according to a new review of the medical literature. These bacteria, which are called Helicobacter pylori, live in the stomachs of humans.... What Is Wild? Odor Attraction Is Different Among Different Wildtype Flies - Vinegar flies (Drosophila melanogaster) show a highly selective behavior towards odor stimuli. A series of behavioral studies showed that a single olfactory stimulus is often not sufficient for immediate attraction to potential food sources or oviposition sites. Interestingly, the behavior differed between investigated D. melanogaster varieties, so-called "wildtypes".... Endoscopic Therapy May Offer An Alternative To Surgery In Patients With Esophageal Cancer - New research has evaluated the long-term efficacy of endoscopic mucosal resection, or EMR, in the treatment of patients with early stage esophageal cancer or Barrett's esophagus. Two separate studies suggest EMR is an effective treatment alternative to surgery and generally yields positive long-term results.... Under Pressure At The Nanoscale, Polymers Play By Different Rules - Scientists putting the squeeze on thin films of polystyrene have discovered that at very short length scales the polymer doesn't play by the rules.... Connections Between Vision And Movement, As They Relate To Perceived Threats, Autism - In research designed to assist US Department of Homeland Security and provide insight into how autistic individuals perceive others, scientists are examining how our visual system helps interpret the intent conveyed in subtle body movements. While most autism research has focused on difficulties in face perception, this new research examines autism as it relates to connections between visual analysis, body movement and our ability to interact.... Unique Fossils Capture ?Cambrian Migration? - A unique set of fossils indicates that 525 million years ago marine animals congregated in Earth's ancient oceans, most likely for migration, according to an international team of scientists. Fossil evidence of collective behavior is extremely rare. But what makes the find even more intriguing is that it indicates that such behavior was occurring at the beginning of the 'Cambrian explosion' -- a major event that saw a vast profusion of complex organisms enter the fossil record for the first time....

Parents Foster Significant Misperceptions Of Children's Weight - Results of a survey have revealed that many parents do not accurately perceive their children as overweight or at risk for adulthood obesity. Obesity in the United States is often accompanied by an increased risk of gastrointestinal diseases and has emerged as a major health concern, particularly the issue of obesity among children and adolescents.... Insects Trained In Quest For Artificial Nose - Researchers have discovered that when training insects, the process of building associations is not a simple matter of strengthening connections through reinforcement. Understanding how associations are built between stimuli and behavior gives insight into the nature of learning and could inform the design of artificial "noses," sensor arrays that can detect chemicals in the air.... Fat-regenerating 'Stem Cells' Found In Mice - Researchers have identified stem cells with the capacity to build fat. Although they have yet to show that the cells can renew themselves, transplants of the progenitor cells isolated from the fat tissue of normal mice can restore normal fat tissue in animals that are otherwise lacking it. The findings may yield insight into the causes of obesity, a condition characterized by an increase in both the size and number of fat cells.... Preserved By Ice: Glacial Dams Helped Prevent Erosion Of Tibetan Plateau - New research suggests that the edge of the Tibetan plateau might have been preserved for thousands of years by ice and glacial debris at the mouth of many tributaries to the Tsangpo River. Those deposits appear to have acted as dams that prevented the rapidly traveling Tsangpo from carving upstream into the plateau.... Pollution From Livestock Farming Affects Infant Health - A new study finds that pollution from livestock facilities is associated with an increase in infant mortality.... Gut Reaction To Arsenic Exposure Simulated - A simulated gastrointestinal system is helping scientists test contaminated soil for its potential to harm humans. The method is likely to save time and money for people hoping to repurpose land with an industrial past. Most testing for potential arsenic exposure is conducted in recognition of a dirty little secret of modern life: Humans unknowingly eat a little bit of soil each day. For children who might play on contaminated soil and ingest dirt, the testing is considered particularly important.... Babies And Beethoven: Infants Can Tell Happy Songs From Sad - A new study shows that 5-month-old babies can distinguish an upbeat tune, such as "Ode to Joy" from Beethoven's Ninth Symphony, from a lineup of gloomier compositions. By age 9 months, babies can do the opposite and pick out the sorrowful sound of Beethoven's Seventh Symphony from a pack of happy pieces.... Brainy Genes, Not Brawn, Key To Success On Mussel Beach - Scientists have found that mussels in their natural habitat express their genes in cyclic waves, in what appears to be a survival strategy akin to the circadian rhythms that govern sleep. In addition, two sets of genes used to cope with heat stress are identified, in the first real-time molecular sampling of two mussel communities.... Important Clue To Learning Deficit In Children With Autism - An important clue to why children with autism spectrum disorders have trouble imitating others has been discovered: they spend less time looking at the faces of people who are modeling new skills....

Scientists Explore Putting Electric Cars On A Two-way Power Street - Think of it as the end of cars' slacker days: No more sitting idle for hours in parking lots or garages racking up payments, but instead earning their keep by providing power to the electricity grid. Scientists are exploring plug-in hybrid electric vehicles that not only use grid electricity to meet their power needs, but return it to the grid, earning money for the owner.... Does It Matter If Black Plus White Equals Black Or Multiracial? - "Is Barack Obama Black or Biracial?" a recent CNN.com headline asks. Should such racial characterizations of people like Obama -- who have one black parent and one white parent -- really matter? According to a new study, they do matter. When study participants knew of a person's black-white ancestry, in comparison to not knowing of the parentage, they quickly adhered to the simplistic characterization of biracial people as black.... How Dust Rings Point To Exo-Earths With Supercomputer's Help - Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets.... Eliminating Viral Vector In Stem Cell Reprogramming - Scientists have eliminated the need for a viral vector in the stem cell reprogramming process In a report in Science, they showed the ability to reprogram adult cells into iPS cells without viral integration into the genome which lays to rest concerns that the reprogramming event might be dependent upon viral integration into specific genomic loci that could mediate the genetic switch....
