| Posted: 02 Mar 2012 06:02 PM PST An international research team has discovered molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. The research was made possible via instruments aboard NASA's Cassini spacecraft.  |
| Important clue uncovered for the origins of a type of supernovae explosion Posted: 02 Mar 2012 04:39 PM PST The origin of an important type of exploding stars -- Type Ia supernovae -- have now been discovered. Studying supernovae of this type helps researchers measure galaxy distances and can lead to important astronomical discoveries.  |
| Posted: 02 Mar 2012 04:39 PM PST Scientists turned to squeezed polymers and free radicals in a search for new energy sources. They found both promise and problems. The researchers demonstrated that radicals from compressed polymers generate significant amounts of energy that can power chemical reactions in water. They also discovered that a silicone polymer commonly used in medical implants releases a large quantity of harmful free radicals when the polymer is under only a moderate amount of pressure.  |
| New computers respond to students' emotions, boredom Posted: 02 Mar 2012 10:25 AM PST Emotion-sensing computer software that models and responds to students' cognitive and emotional states -- including frustration and boredom -- has now been developed.  |
| World's best measurement of W boson mass points to Higgs mass and tests Standard Model Posted: 02 Mar 2012 10:24 AM PST The latest measurement of the mass of the W boson from the Tevatron experiments. The new combined result is twice as precise as the previous world average, and places limits on the mass of the Higgs consistent with the limits from direct searches at the LHC and Tevatron.  |
| Solved: Mystery of the nanoscale crop circles Posted: 02 Mar 2012 07:18 AM PST A useful alloy of gold and silicon, called a eutectic, melts at a far lower temperature than either of its components. Until now, however, its odd behavior on the nanoscale has confounded researchers. By analyzing peculiar "nanoscale crop circles" formed from ultra-thin layers of gold on silicon, scientists have discovered the eutectic alloy's unique properties, including its special promise for engineering and processing nanoscale materials.  |
| Dark matter core, left behind from wreck between massive clusters of galaxies, defies explanation Posted: 02 Mar 2012 07:14 AM PST Astronomers using data from NASA's Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision.  |
| Pasta-shaped radio waves beamed across Venice Posted: 02 Mar 2012 05:30 AM PST A group of Italian and Swedish researchers appears to have solved the problem of radio congestion by cleverly twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received.  |
| Analyses of a tiny comet grain dates Jupiter's formation Posted: 01 Mar 2012 07:39 AM PST Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System.  |
| Graphene-based optical modulators poised to break speed limits in digital communications Posted: 01 Mar 2012 07:38 AM PST In yet another astounding application of the "wonder material" graphene, scientists have discovered that it makes an excellent active media for optical modulators. Graphene-based modulators are expected to significantly enhance ultra-fast optical communication and computing.  |
