| An older Vega: New insights about the star all others are measured by Posted: 11 Dec 2012 12:44 PM PST Vega, a star astronomers have used as a touchstone to measure other stars' brightness for thousands of years, may be more than 200 million years older than previously thought.  |
| Mussel goo inspires blood vessel glue Posted: 11 Dec 2012 12:44 PM PST A researcher has helped create a gel -- based on the mussel's knack for clinging to rocks, piers and boat hulls -- that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.  |
| Posted: 11 Dec 2012 11:52 AM PST Rose madder -- a natural plant dye once prized throughout the Old World to make fiery red textiles -- has found a second life as the basis for a new "green" battery. Chemists have developed a non-toxic and sustainable lithium-ion battery powered by purpurin, a dye extracted from the roots of the madder plant.  |
| Grains gang up to bear brunt of missile and meteorite impacts Posted: 11 Dec 2012 11:52 AM PST High-speed video of projectiles slamming into a bed of disks has given scientists a new microscopic picture of the way a meteorite or missile transfers the energy of its impact to sand and dirt grains.  |
| Best of both worlds: Hybrid approach sheds light on crystal structure solution Posted: 11 Dec 2012 10:03 AM PST Understanding the arrangement of atoms in a solid is vital to materials research -- but the problem can be difficult to solve in many important situations. Now, by combining the work of two different scientific camps, researchers have created an algorithm that makes crystal structure solution more automated and reliable.  |
| Black holes have properties that resemble dynamics of both solids and liquids Posted: 11 Dec 2012 08:29 AM PST Black holes are surrounded by many mysteries, but now researchers have come up with new groundbreaking theories that can explain several of their properties. The research shows that black holes have properties that resemble the dynamics of both solids and liquids.  |
| Alternative to fullerenes in organic solar cells is just as exciting Posted: 11 Dec 2012 06:49 AM PST An insight into the properties of fullerene is set to open the door to a new class of electronic acceptors which can be used to build better and cheaper organic solar cells.  |
