| Social sensing game detects classroom bullies Posted: 19 Nov 2014 12:17 PM PST Researchers have developed a computer game that can detect classroom bullies, victims and bystanders. The game's behavior analyses effectively identify classroom bullies, even revealing peer aggression that goes undetected by traditional research methods, the researchers say. |
| Thin film produces new chemistry in 'nanoreactor' Posted: 19 Nov 2014 10:25 AM PST Physicists have discovered a new manganese compound that is produced by tension in the crystal structure of terbium manganese oxide. The technique they used to create this new material could open the way to new nanoscale circuits. |
| Rosetta continues into its full science phase Posted: 19 Nov 2014 10:18 AM PST With the Philae lander's mission complete, Rosetta will now continue its own extraordinary exploration, orbiting Comet 67P/Churymov-Gerasimenko during the coming year as the enigmatic body arcs ever closer to our Sun. |
| A jettisoned black hole? Or a giant star exploding over several decades? Posted: 19 Nov 2014 08:25 AM PST Astronomers have discovered an object in space that might be a black hole catapulted out of a galaxy. Or, according to an alternative interpretation, it might be a giant star that is exploding over an exceptionally long period of several decades. In any case, one thing is certain: This mysterious object is something quite unique, a source of fascination for physicists the world over because of its potential to provide experimental confirmation of the much-discussed gravitational waves predicted by Albert Einstein. |
| Biochemists build largest synthetic molecular 'cage' ever Posted: 19 Nov 2014 07:20 AM PST Biochemists have created the largest protein ever that self-assembles into a molecular cage. Their designed protein, which does not exist in nature, is hundreds of times smaller than a human cell. The research could lead to 'synthetic vaccines' that protect people from the flu, HIV and perhaps other diseases. It could also lead to new methods of delivering pharmaceuticals inside of cells and the creation of new nano-scale materials. |
| Testing if a computer has human-level intelligence: Alternative to 'Turing test' proposed Posted: 19 Nov 2014 07:17 AM PST Researchers are offering an alternative to the celebrated "Turing Test" to determine whether a machine or computer program exhibits human-level intelligence. |
| Gifted men and women define success differently, 40-year study finds Posted: 19 Nov 2014 07:17 AM PST Researchers spent four decades studying a group of mathematically talented adolescents, finding that by mid-life they were extraordinarily accomplished and enjoyed a high level of life satisfaction. Gender, however, played a significant role in how they pursued—and defined—career, family and success. Intellectually gifted women tracked for 40 years were found to earn less money, be less present in STEM fields, and work fewer hours than their male counterparts. Despite that, they expressed a high level of personal satisfaction and sense of achievement, defining success more broadly than men to include family and community service. These observations come from the most recent round of results from the Study of Mathematically Precocious Youth (SMPY), the largest longitudinal research project of its kind. The results were posted this week to Psychological Science. |
| A 3-D, talking map for the blind (and everyone else) Posted: 19 Nov 2014 07:16 AM PST Developers have built and tested a new kind of interactive wayfinder: 3-D maps that vocalize building information and directions when touched. |
| Spooky alignment of quasars across billions of light-years Posted: 19 Nov 2014 05:45 AM PST New observations with ESO's Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to be aligned with the vast structures in the cosmic web in which they reside. |
| Scientists get to the heart of fool's gold as a solar material Posted: 18 Nov 2014 03:25 PM PST As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity. Theoretically, iron pyrite could do the job, but when it works at all, the conversion efficiency remains frustratingly low. Now, a research team explains why that is, in a discovery that suggests how improvements in this promising material could lead to inexpensive yet efficient solar cells. |
