Have the super-scientific brain needed to develop laser technology for enhancing everything from radar scanning to X-ray machines? The Defense Advanced Research Projects Agency wants you, doc.

DARPA this week called on radiation experts and other brainiacs to propose methods of efficiently controlling the electromagnetic spectrum by using ultrafast, pulsed lasers operating at optical wavelengths. It's part of DARPA's program in ultrafast laser and engineering, or PULSE. … Read more

Citing a lack of innovation in fire-extinguishing methods over the last 50 years, the Defense Advanced Research Projects Agency (DARPA) last week revealed an ear-buzzing new method for putting out fires: blast it with fine-tuned frequencies.

Officially referred to as "acoustic suppression of flame," this simple yet potentially revolutionary method simply relies on two speakers playing a specific low frequency toward the fire.

The resulting acoustics increase air velocity, making it easier to alter the origin of the fire's combustion, also known as the flame boundary layer. … Read more

For most ordinary citizens, leaked information from a smartphone or tablet is a hassle but not a life-or-death situation. But for soldiers it can be another story.

The U.S. government is working to reinforce soldiers' devices against data breaches. According to The New York Times, the Defense Advanced Research Projects Agency, or DARPA, has given a $21 million grant to the company Invincea to protect soldiers' Android-based phones and tablets from cyber threats.

"By separating untrusted apps and content we are preventing the compromise of the operating system," founder of Invincea Anup Ghosh told The New York … Read more

An unmanned Air Force space plane dropped out of orbit and glided to a computer-controlled California landing early Saturday to close out a classified 469-day military mission.

The reusable Boeing-built X-37B Orbital Test Vehicle touched down on a runway at Vandenberg Air Force Base, Calif., at 5:48 a.m. PDT (GMT-7). The Air Force did not provide any advance warning of the re-entry and landing time and no technical details about the vehicle's performance were released.

But in a statement, the Air Force said the autonomous landing by the nation's "newest and most advanced re-entry spacecraft&… Read more

The Defense Department has reportedly ordered augmented-reality displays from startup Innovega, only a week after Google disclosed its own augmented-reality project.

Bellevue, Wash.-based Innovega has signed a contract to supply the Defense Advanced Research Projects Agency (DARPA) with a prototype of its iOptik spectacles and accompanying contact lenses, Innovega's CEO Steve Willey told the BBC. The augmented-reality system could improve the awareness of soldiers in the field, he said.

The contact lenses have a filter that allows a person to focus on images at a very close distance and focus on far-away objects at the same time. That … Read more

If DARPA gets its way, robots will be able to drive, unlock doors, and fix leaking pipes.

The agency today released details of its Robotics Challenge, an initiative to award up to $34 million in grants to improve robots for disaster response operations. Teams will compete for as much as $2 million for a single entry.

The robots themselves don't need to take a human form, but many of the tasks DARPA's challenge addresses favor robots in humanoid form. The challenge lays out a number of jobs the robot needs to address that would be helpful in the … Read more

Humanoid-robot soldiers may be getting closer to reality with DARPA's next Grand Challenge, which apparently will involve getting a robot to pull off some pretty impressive handyman skills.

According to robotics Web site Hizook, DARPA's Gill Pratt recently outlined the challenge, which calls for humanoids to be used in industrial disasters and rough terrain.

The ultimate object is to build a robot that can work in a human environment and use human tools. The industrial setting is no surprise in the aftermath of Japan's Fukushima nuclear crisis, in which various robots from the U.S. have lent a helping hand (or manipulator). … Read more

Boston Dynamics, creator of the very awesome BigDog and a menagerie of other bots, is sending two small reconnaissance robots to the U.S. Army for testing.

Sand Flea and RHex, developed with funding from the Army's Rapid Equipping Force, are off to the Army Test and Evaluation Command (ATEC) to pass safety and reliability assessments.

Three RHex units have already been delivered to ATEC and Sand Fleas will join them later this year, Boston Dynamics said in a release. The machines could improve soldiers' awareness of threats in war zones.

RHex is a six-legged, 30-pound crawling bot inspired … Read more

If you had to track down fugitives hidden in five cities around the world, would one day and a $5,000 reward be enough to succeed? And if so, how?

That's what the people behind the TAG Challenge want to know--and what the whole world will soon find out.

On March 31, mug shots of five "suspects" will be published, and it'll be game on in a global hunt for "jewel thieves" in Bratislava, Slovakia; Stockholm; London; Washington, D.C.; and New York City, each of whom will spend 12 hours that day in … Read more
