A simple sensor circuit made of hard-to-handle but promising carbon nanotubes is a first step in making the materials practical for computing, MIT Technology Review reports. Transistors made from these nanomaterials are faster and more energy efficient than silicon ones, and computer models predict that carbon nanotube processors could be ten times less power-hungry. But … more… |
Giant laser creates an artificial star to clear the sky

Death Star’s superlaser? No, a new, improved laser that acts as an artificial star, as a reference to monitor atmospheric turbulence for the Very Large Telescope in Chile, compensating for the atmosphere’s distortions and creating much sharper images, reports New Scientist. The laser shoots 90 kilometers into the atmosphere, where it interacts with the 10-kilometer-thick layer of … more… |
Android smartphone to control satellite in orbit
 |
|
A satellite with an Android Google Nexus One smartphone at its heart is now orbiting the Earth at an altitude of 785 kilometers. Called STRaND-1, the UK’s first cubesat, the satellite’s incorporation of a phone is a bold attempt to test how well cheap, off-the-shelf consumer electronics handle the harsh temperature variations and microchip-blasting cosmic … more… |
Graphene micro-supercapacitors to replace batteries for microelectonics devices
 |
|
UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate miniature graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom–thick layer of carbon, can be easily manufactured and readily integrated into small devices, such as … more… |
‘Wet’ computer server could cut wasted energy for cooling
 |
|
A revolutionary liquid-cooled computer server design that could slash the carbon footprint of the Internet is being tested at the University of Leeds. Unlike most computers, which use air to cool their electronics, all of the components in the new server are completely immersed in liquid. The power-hungry fans of traditional computing are replaced by … more… |
