| Posted: 30 Nov 2011 02:56 PM PST The NASA Kepler Mission is designed to survey a portion of our region of the Milky Way Galaxy to discover Earth-size planets in or near the "habitable zone," the region in a planetary system where liquid water can exist, and determine how many of the billions of stars in our galaxy have such planets. It now has another planet to add to its growing list. Researchers have shown that one of the brightest stars in the Kepler star field has a planet with a radius only 1.6 that of Earth's radius and a mass no greater that 10 earth masses, circling its parent star with a 2.8 day period.  |
| NASA's Swift finds a gamma-ray burst with a dual personality Posted: 30 Nov 2011 02:10 PM PST A peculiar cosmic explosion first detected by NASA's Swift observatory on Christmas Day 2010 was caused either by a novel type of supernova located billions of light-years away or an unusual collision much closer to home, within our own galaxy.  |
| Fully printed carbon nanotube transistor circuits for displays Posted: 30 Nov 2011 01:15 PM PST Researchers outline the first practical demonstration of carbon nanotube transistor based printed circuits for display backplane applications revealing CNT's viable candidacy as a competing technology alongside amorphous silicon and metal oxide semiconductor solution as a low-cost and scalable backplane option.  |
| In a star's final days, astronomers hunt 'signal of impending doom' Posted: 30 Nov 2011 11:22 AM PST An otherwise nondescript binary star system in the Whirlpool Galaxy has brought astronomers tantalizingly close to their goal of observing a star just before it goes supernova.  |
| Astronomers look to neighboring galaxy for star formation insight Posted: 30 Nov 2011 11:19 AM PST An international team of astronomers has mapped in detail the star-birthing regions of the nearest star-forming galaxy to our own, a step toward understanding the conditions surrounding star creation. They found a large number of relatively low-mass clouds of molecular hydrogen -- material for star forming -- and found a correlation between young massive stars and molecular clouds.  |
| At a crossroads: New research predicts which cars are likeliest to run lights at intersections Posted: 30 Nov 2011 09:01 AM PST Researchers have developed an algorithm that predicts which cars are likeliest to run lights at intersections.  |
| Controlled disorder: Scientists find way to form random molecular patterns Posted: 30 Nov 2011 06:51 AM PST Scientists have discovered a way to control how tiny flat molecules fit together in a seemingly random pattern.  |
| 'Graphene earns its stripes': New nanoscale electronic state discovered on graphene sheets Posted: 29 Nov 2011 08:21 AM PST Researchers have discovered electronic stripes, called 'charge density waves', on the surface of the graphene sheets that make up a graphitic superconductor. This is the first time these stripes have been seen on graphene, and the finding is likely to have profound implications for the exploitation of this recently discovered material, which scientists believe will play a key role in the future of nanotechnology.  |
