A U.S. Pentagon invention could make air combat resemble a battle scene from the movie 'Star Wars' with a laser so small it can fit on a fighter jet, yet powerful enough to knock down an enemy missile in flight.
A revolutionary machine that can copy itself and manufacture everyday objects quickly and cheaply could transform industry in the developing world, according to its creator.
Newly released military video reveals unmanned U.S. Predators firing Hellfire missiles to rescue U.S. troops under fire in Iraq and destroy insurgent targets.
Rat cells grown onto microscopic silicon chips worked as tiny robots, perhaps a first step towards a self-assembling device.
Scientists at the University of the West of England (UWE) have designed a robot that does not require batteries or electricity to power itself. Instead, it generates energy by catching and eating houseflies.
Russia has successfully tested a modernized anti-missile missile, which defense analysts are interpreting as a direct response to the US withdrawl from the anti-ballistic missile treaty.
A Boeing Co.-led team has successfully fired for the first time a powerful laser meant to fly aboard a modified 747 as part of a U.S. ballistic missile defense shield.
It's just an idea on paper, but the U.S. Air Force is asking defense contractors how they might develop a 30,000-pound, precision-guided bomb that could destroy targets deep underground, in caves or in hardened bunkers.
A robotic plane deliberately dropped a bomb near a truck, marking another step forward for technology the U.S. military hopes will one day replace human pilots on dangerous combat missions.
While its benefits are still years away from reaching the public, scientists hope nanotechnology -- the manipulation of atoms as raw materials -- will eventually live up to the hype it's received for its potential to advance medicine, electronics and manufacturing.
