    Advancements in silicon-germanium have been going on for years now, but a team at UCLA is convinced that their discovery really is "the next big thing." For scores now, microchip makers have struggled with miniaturizing transistors as the public at large demands that things get smaller and smaller. Thanks to researchers at the aforesaid university, it's looking like silicon-germanium nanowires could be the key to making the process a whole lot easier. According to study co-author Suneel Kodambaka, the new nanowires could "help speed the development of smaller, faster and more powerful electronics," also noting that they're so small that they can be "placed in virtually anything." Which is great, because the Adamo XPS is just entirely too pudgy.

  • IBM, GIT overclock chip to 500GHz

    If you were wowed by those Japanese modders who overclocked their stock CPU to 7GHz, wait till you hear about IBM's latest foray into the world of ultra-fast computing: together with researchers from the digital camera-hating Georgia Institute of Technology, Big Blue has managed to overclock a chip to an unheard of 500GHz. Granted, the model they used already had a blistering native clock speed of 350GHz to begin with, but we're still floored that you could actually coax a small silicon wafer into operating at an incredible half-terahertz. As you probably suspected, there's no way to achieve speeds like this at room temperature, so the team froze their high-performance silicon-germanium chip to a super-chilly negative 451-degrees Fahrenheit, which is just eight degrees above absolute zero. Unfortunately, after learning about this breakthrough, electronics giant Sony apparently felt that consumers would no longer be impressed with their much-hyped Cell processor, so they've once again delayed the PS3 until IBM can make the liquid helium-cooled CPUs suitable for mass production . Expect the 500GHz PS3 to hit stores sometime in 2011.[Thanks, bento-san]
