University Claims to Have Developed World’s First Flexible Touchscreen Display
ASU's Flexibile Display Center and military partners have developed the very first display with a flexible touchscreen. Mainly designed for military applications, the screen is made out of glass strong enough to withstand the battlefield. Instead of using solid glass for the touchscreen, the
Ferrari Gets a Limited Edition Motorola Milestone
As if owning a Ferrari wasn’t enough of a status symbol, the company has tasked Motorola with a custom deco of the original Milestone to slide into pockets lined with one hundred dollar bills. The phone looks pretty delicious in Ferrari red, but if you are hoping to get your hands on it you migh
Windows Live Messenger 2009 v14.0.8064.0206 & A-Patch 143b2
The Windows Live Suite has been updated to 14.0.8064.0206 from v14.0.8050.1202. Currently there isn’t any information on changes. As usual you can get it through the Windows Live Installer “web edition” or “full edition” with sizes of 1.09MB and 133.57MB. And if you want to get the st
Russia Wants Nuclear-Powered Rocket to Go to Mars
The space race is on again: The Russians are planning a nuclear-powered spacecraft that will get them to Mars faster than Duck Dodgers in the 24 and a half century. Space Agency chief Anatoly Perminov promises a design by 2012: The project is aimed at implementing large-scale space exploration prog

Lithium-ion batteries are already close to the 20-hour life promised back in 2007 for laptops, but Lithium-sulphur batteries being worked on at Stanford University may improve battery life by 300 per cent.
It’s the same team of researchers that impressed us back in ’07 with tales of long-lasting Lithium-ion, but it seems the future is in Lithium-sulphur batteries—specifically with the “recent development of sulfur/mesoporous carbon nanocomposite cathodes,” as mentioned in Nano Letters:
“The recent development of sulfur/mesoporous carbon nanocomposite cathodes represents a particularly exciting advance, but in full battery cells, sulfur-based cathodes have to be paired with metallic lithium anodes as the lithium source, which can result in serious safety issues”
“Here we report a novel lithium metal-free battery consisting of a Li2S/mesoporous carbon composite cathode and a silicon nanowire anode”
“This new battery yields a theoretical specific energy…which is four times that of the theoretical specific energy of existing lithium-ion batteries based on LiCoO2 cathodes and graphite anodes.”
Unfortunately for those of us wishing upon a star each night for longer battery life in our gadgets, Stanford University’s research is unlikely to be seen in products any time soon, due to its low charge cycles of between 40 – 50, significantly lower than Lithium-ion’s 300 – 500.
