• This weekend: 32nd annual computing Battle of the Brains

    The 32nd annual collegiate programming contest will take place this weekend in Alberta, Canada; one hundred three-person teams from thirty-three countries have qualified; twenty of the teams represent U.S. colleges

  • Australia, Japan in joint clean-coal project

    The Australian and Japanese government, and several companies join in retrofitting a coal-fired boiler at Callide A power station in Central Queensland with oxy-firing technology which will burn coal in a mixture of oxygen and recirculated flue gases

  • Steve Ballmer talks of "fifth computing revolution"

    Microsoft’s CEO outlines the five pillars of the fifth computing revolution: Expanded processing power, huge amounts of storage, ubiquitous broadband, natural user interface (UI), and screens everywhere

  • Questions raised anew about space elevator stability

    As we place more systems in space — soon, perhaps, weapon platforms to counteract China’s growing anti-satellite warfare capabilities — there is a growing need to service and maintain these systems; one way to do so relatively on the cheap is to build a space elevator, but the stability of such an elevator is raising questions

  • Southern California utility to push solar power

    Southern California Edison, largest utility in California, will place 250 MW of photovoltaic generators on 65 million square feet of roofs of Southern California commercial buildings

  • Four-legged robot simulates human motion

    Four-legged, all-terrain robot can maintain its balance over rugged terrain while carrying a payload of up to 340 pounds; robot can also cope with man-made obstacles and gallop (well, something between “gallop” and “canter”) over impediments

  • U.K.'s Future Soldier / Science and Engineering Week a success

    Two events — Future Soldier and National Science and Engineering Week — took place in London, showing how government, industry, and academia can fruitfully cooperate to promote science, engineering, and technology education

  • World's largest caliber supersonic railgun successfully tested

    DARPA-sponsored railgun successfully launches a full-sized projectile, with size and weight similar to a 120 mm mortar, at speeds of 430 meters-per-second

  • New acoustic system locates snipers with accuracy

    System detects the sound of an initial gunshot then the shockwave from the muzzle of the weapon being fired; since sound travels faster than a shockwave, the system is able to pinpoint the position of the attacker

  • Intelligent wireless networks promoted by European consortium

    The proliferation of wireless communication-enabled embedded systems will have significant effects in areas from emergency management to critical infrastructure protection to healthcare and traffic control; European consortium to promote idea

  • Breakthrough: Dramatic increase in thermoelectric efficiency achieved

    Two hundred years ago scientists discovered the thermoelectric effect: Certain materials can convert heat into electricity and vice versa; trouble is, most materials which conduct electricity also conduct heat, so their temperature equalizes quickly; until now: Boston College, MIT researchers solve this vexing problem

  • Pencilbeam X-ray technology for more effective luggage inspection

    New luggage screening technology investigates suspicious material by penetrating the luggage with a pencilbeam X-ray; new approach reduces instances of false alarms

  • Cat's eyes locate things underwater

    A new underwater cat’s eye can reflect back a tuned signal, revealing its location, to existing sonar systems; new device does not use batteries — and it does rely on toxic chlorofluorocarbons (CFCs)

  • Ambient blue light resets tired workers' body clocks

    Tedious work during the “wrong” hours of the body’s biological clock — think truckers who drive through the night, or security officers monitoring CCTV screens during the graveyard shift — often leads to drowsiness; falling asleep behind the wheel or in front of a security monitoring screen can lead to catastrophes; researchers develop a way to “fool” the brain to think it is morning

  • UCSD researchers develop tiny explosive sensor

    Sensor works by monitoring the variability of electrical conductivity through thin films of metal phthalocyanines; “The detection capability of this tiny electronic sensor is comparable to current instruments, which are large, bulky and cost thousands of dollars each,” says William Trogler, UCSD professor of chemistry and biochemistry
