'Sleep talking' PCs save energy and money
Personal computers may soon save large amounts of energy by "sleep talking." Computer scientists at UC San Diego and Microsoft Research have created a plug-and-play hardware prototype for personal computers that induces a new energy saving state known as "sleep talking." Normally PCs can be in either awake mode - where they consume power even if they are not being used, or in a low power sleep mode - where they save substantial power but are essentially inactive and unresponsive to network traffic. The new sleep talking state provides much of the energy savings of sleep mode and some of the network-and-Internet-connected convenience of awake mode. more

Excitons eliminate a 'speed trap' between computing and communication signals
Particles called excitons that emit a flash of light as they decay could be used for a new form of computing better suited to fast communication, physicists at UC San Diego have demonstrated. more

Radical New Thin Lens for Camera Phones
Engineers at the University of California San Diego (UCSD) have built a powerful yet ultrathin digital camera by folding up the telephoto lens. This technology may yield lightweight, ultrathin, high resolution miniature cameras for use in mobile phones. more
