New system could predict solar flares, give advance warning Posted: 13 Aug 2012 12:57 PM PDT Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and astronauts from potentially dangerous radiation.

Egg yolk consumption almost as bad as smoking when it comes to atherosclerosis, study suggests Posted: 13 Aug 2012 12:56 PM PDT Newly published research shows that eating egg yolks accelerates atherosclerosis in a manner similar to smoking cigarettes. Surveying more than 1,200 patients, Dr. Spence found regular consumption of egg yolks is about two-thirds as bad as smoking when it comes to increased build-up of carotid plaque, a risk factor for stroke and heart attack.

Gamma rays from galactic center could be evidence of dark matter Posted: 13 Aug 2012 12:55 PM PDT Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space, according to new research.

A new energy source: Major advance made in generating electricity from wastewater Posted: 13 Aug 2012 12:55 PM PDT Engineers have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves while cleaning sewage, but will sell excess electricity.

Florida state record 87 eggs in largest python from Everglades Posted: 13 Aug 2012 12:55 PM PDT Researchers curating a 17-foot-7-inch Burmese python, the largest found in Florida, discovered 87 eggs in the snake, also a state record.

Research raises doubts about whether modern humans and Neanderthals interbred Posted: 13 Aug 2012 12:55 PM PDT New research raises questions about the theory that modern humans and Neanderthals at some point interbred, known as hybridization. The findings suggest that common ancestry, not hybridization, better explains the average 1-4 per cent DNA that those of European and Asian descent (Eurasians) share with Neanderthals.

How computation can predict group conflict: Fighting among captive pigtailed macaques provides clues Posted: 13 Aug 2012 12:55 PM PDT When conflict breaks out in social groups, individuals make strategic decisions about how to behave based on their understanding of alliances and feuds in the group. But it's been challenging to quantify the underlying trends that dictate how individuals make predictions, given they may only have seen a small number of fights or have limited memory. In a new study of primates (pigtailed macaques), scientists have developed a computational approach to determine whether individuals behave predictably.

Fresh water breathes fresh life into hurricanes Posted: 13 Aug 2012 12:55 PM PDT An analysis of a decade's worth of tropical cyclones shows that when hurricanes blow over ocean regions swamped by fresh water, the conditions can unexpectedly intensify the storm. Although the probability that hurricanes will hit such conditions is small, ranging from 10 to 23 percent, the effect is potentially large: Hurricanes can become 50 percent more intense, researchers report.

Scientists 'waltz' closer to using spintronics in computing Posted: 13 Aug 2012 09:30 AM PDT Aiming to use electron spins for storing, transporting and processing information, researchers have revealed the first-ever direct mapping of the formation of a persistent spin helix in a semiconductor.

CERN’s Large Hadron Collider experiments bring new insight into matter of the primordial Universe Posted: 13 Aug 2012 08:54 AM PDT Experiments using heavy ions at CERN's Large Hadron Collider (LHC) are advancing understanding of the primordial Universe. Scientists have made new measurements of the kind of matter that probably existed in the first instants of the Universe.

New bacteria-resistant materials discovered Posted: 13 Aug 2012 04:40 AM PDT Using state-of-the-art technology, scientists at have discovered a new class of polymers that are resistant to bacterial attachment. These new materials could lead to a significant reduction in hospital infections and medical device failures.
