    Advocates of hydrogen fuel-cell propulsion have a new target for their technology: trolleys. At the Fifth International Hydrail conference, held 11 and 12 June in Charlotte, N.C., engineers and transit planners concluded that streetcars are an ideal early application for hydrogen propulsion. Traditional trolley cars have drawn their power from catenaries, unsightly overhead electricity supply line... View full abstract»

    The British communications ministry has released a road map calling for the completion of the nation's move from analog FM to the digital audio broadcast (DAB) standard by the end of 2015. But DAB skeptics say that the move will waste money and that consumers just aren't interested. Conversion will require anywhere from 120 to 700 new transmitters, according to Eureca Research analyst Gareth Owen,... View full abstract»

    For years, developers of face-recognition algorithms have been battling the effects of awkward poses, facial expressions, and disguises like hats, wigs, and fake moustaches. They've had some success, but they may be meeting their match in plastic surgery. View full abstract»

    On an afternoon in late July, Tony Eastham sat in a half-built office outside Jeddah, in Saudi Arabia. A table, a few chairs still wrapped in plastic, a desk, and some white settees occupied the room. Outside, the whines and growls of construction heralded the rise of a university in the desert.

    Graphene, a one-atom-thick layer of carbon atoms, is the strongest material ever tested and more conductive than the purest silver. Since its isolation in 2004, scientists have been dreaming of impossibly tiny graphene transistors. But there's a major challenge: The material has no electronic band gap, the semiconductor property that controls the operations of transistors, lasers, and other solid-... View full abstract»

    It's a bird! It's a plane! It's¿gone? Illusionist Franz Harary first wowed audiences 15 years ago by making the space shuttle disappear. "There's a kind of glass that becomes reflective when electrically charged, so you're able to produce and vanish objects by turning their reflections on and off," he says. View full abstract»

    The computer inside a BlackBerry or iPhone boots up in seconds, so why can't your laptop? Some of Microsoft Windows' start¿up time is inevitable, says computer architect Peter Glaskowsky, an analyst with the Envisioneering Group, in Seaford, N.Y. "There's too much to do¿initialize all of memory, start up the hard disk, assign virtual memory, and more." He says even embedded systems like an iPhon... View full abstract»

    Why graphics processors will transform database processing?. The graphics coprocessor, invented in the 1970s to churn through voluminous and repetitive calculations and render smooth and realistic-looking images on computer screens, can now chew on large-scale databases. Database processing is a cornerstone of computing, and it is a market that last year generated approximately US $27 billion, acc... View full abstract»
