| New chemical reaction could explain how stars form, evolve, and eventually die Posted: 07 Dec 2012 02:44 PM PST Researchers have discovered a molecular-level interaction that science had puzzled over for decades but had never seen. That discovery, it turns out, may redefine how science views chemical compound formation. It also answers questions about what goes on in places like white dwarfs, the super dense cores of stars nearing the end of their life cycles.  |
| Posted: 07 Dec 2012 07:17 AM PST Engineers have created a device that can focus light into a point just a few nanometers (billionths of a meter) across -- an achievement they say may lead to next-generation applications in computing, communications, and imaging.  |
| NASA's Van Allen Probes reveal new dynamics of Earth's radiation belts Posted: 07 Dec 2012 07:09 AM PST Just 96 days since their launch, NASA's twin Van Allen Probes have already provided new insights into the structure and behavior of the radiation belts that surround Earth, giving scientists a clearer understanding about the fundamental physical properties of these regions more than half a century after their discovery.  |
| X-ray vision can reveal moment of birth of violent supernovae Posted: 07 Dec 2012 06:04 AM PST Astronomers have uncovered new evidence that suggests that X-ray detectors in space could be the first to witness new supernovae that signal the death of massive stars.  |
| Copper, gold and tin for efficient chips Posted: 06 Dec 2012 09:18 AM PST With gold, copper or tin and special galvanizing processes, scientists are improving the function of semi-conductors and making the manufacture of microelectronic systems a child's play. Especially the LED industry could profit from this.  |
