| Graphene nanocomposite a bridge to better batteries Posted: 27 Jul 2011 02:15 PM PDT Researchers have built a high-capacity energy storage device for lithium ion batteries by constructing a unique nanoscale sandwich of graphene and tin. The device is engineered to improve electrochemical cycling of the battery, which reduces charging time and allows repeated recharging without degrading battery performance.  |
| NASA's WISE finds Earth's first 'trojan' asteroid Posted: 27 Jul 2011 02:02 PM PDT Astronomers studying observations taken by NASA's Wide-field Infrared Survey Explorer (WISE) mission have discovered the first known "Trojan" asteroid orbiting the sun along with Earth.  |
| Fundamental matter-antimatter symmetry confirmed Posted: 27 Jul 2011 01:11 PM PDT An international collaboration has set a new value for the antiproton mass relative to the electron with unprecedented precision.  |
| Pigment discovery expanding into new colors Posted: 27 Jul 2011 12:14 PM PDT Chemists have discovered that the same crystal structure they identified two years ago to create what may be the world's best blue pigment can also be used with different elements to create other colors, with significant potential in the paint and pigment industries.  |
| New material lets electrons 'dance' and form new state Posted: 27 Jul 2011 11:13 AM PDT Scientists have successfully created an ultrapure material that captures new states of matter and could have applications in high-speed quantum computing. The material, gallium arsenide, is used to observe states in which electrons no longer obey the laws of single-particle physics, but instead are governed by their mutual interactions.  |
| Chandra X-ray Observatory images gas flowing toward black hole Posted: 27 Jul 2011 10:38 AM PDT The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays. The observations from NASA's Chandra X-ray Observatory will help tackle two of the most fundamental problems in modern astrophysics: understanding how black holes grow and how matter behaves in their intense gravity.  |
| Wave power can drive sun's intense heat Posted: 27 Jul 2011 10:14 AM PDT A new study sheds light on why the sun's outer atmosphere, or corona, is more than 20 times hotter than its surface. The research may bring scientists a step closer to understanding the solar cycle and the sun's impacts on Earth.  |
| Posted: 27 Jul 2011 09:26 AM PDT Cilia -- tiny hair-like structures that perform feats such as clearing microscopic debris from the lungs and determining the correct location of organs during development -- move in mysterious ways. Researchers have created artificial cilia-like structures that offers a new approach for cilia study.  |
| Bionic microrobot mimics the 'water strider' and walks on water Posted: 27 Jul 2011 09:16 AM PDT Scientists are reporting development of a new aquatic microrobot that mimics the amazing water-walking abilities of the water strider -- the long-legged insect that scoots across the surface of ponds, lakes and other waterways. The bionic microrobot incorporates improvements over previous devices of this kind that position it as a prime candidate for military spy missions, water pollution monitoring, and other applications, the scientists say.  |
| New invisibility cloak hides objects from human view Posted: 27 Jul 2011 09:16 AM PDT For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans. The new device is a leap forward in cloaking materials.  |
| Posted: 27 Jul 2011 09:15 AM PDT "Brain cap" technology now being developed allows users to turn their thoughts into motion. Researchers have created a noninvasive, sensor-lined cap with neural interface software that soon could be used to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars.  |
