Run, don't walk, if you want to get away from this cheetah robot. If you happen to be non-human, you might stand a chance of surviving.

That's because Boston Dynamics' quadruped has set a new speed record and can now outrun the world's fastest human, Usain Bolt.

The DARPA-funded cyber-cat, already the fastest legged robot around, can sprint 28.3 mph, better than Bolt's best 20-meter split of 27.78 mph, the company said, quoting data from the International Association of Athletics Federations. The robot can now run significantly faster than its former top speed of 18 mph because engineers increased its power and refined the leg control algorithms. … Read more

Powerful explosives from fires or roadside bombs produce two near-simultaneous blasts: first, a high-pressure blast that can cause internal injuries, and then a thermal blast that produces temps above 1,000 degrees Fahrenheit and can literally cook skin, according to Robert Lochhead, a professor of polymer science at the University of Southern Mississippi.

He worked with chemists to engineer a high-tech camouflage paint that is waterproof; easy to apply and remove; non-irritating to the eyes, nose, and mouth; and actually reflects -- instead of absorbs, like most face paints -- intense heat.… Read more

In addition to slithering, crawling, and flying just about anywhere, what if robots could camouflage themselves? This tentacled prototype can be made to look like -- or stand out from -- its background with a simple injection of dyes.

Developed by engineers at Harvard University's Whitesides Research Group, the "soft machine" silicone quadruped crawls along on pressurized gases fed through an umbilical cord.

Users can send different dyes through channels in the robot's body, allowing it to blend in or stand out in startling fashion, such as glowing in the dark. Color changes take about 30 seconds, but don't require further power to sustain the disguise. … Read more

When the going gets tough, the Defense Advanced Research Projects Agency creates a vehicle -- capable of driving on water, land, and even deep mud -- to keep things going.

Officially known as the captive air amphibious transporter (CAAT), this water wagon currently under development looks like the strange lovechild of a tank and a hovercraft. CAAT could one day serve as an invaluable tool for the U.S. military when it delivers supplies to the coasts of disaster-stricken areas. … Read more

From snakes to fish to cheetahs, we've seen a veritable Noah's Ark of biomimetic robots in recent years, and now researchers have turned to the lowly earthworm for inspiration.

Meshworm is a squishy, sluglike droid that stretches and squeezes its artificial muscles to move forward. This peristalsis is similar to how worms travel and how your guts move food around. … Read more

U.S. Army, welcome to the future.

If you happen to be in Farnborough, London, this week, you'll be able to see a demo of an Army pilot geared in the latest in wearable military technology -- a portable computing device that fits in a pocket and a display panel that can be strapped to a soldier's wrist.

The entire Aviation Warrior (yes, that's what it is called) system -- which includes a helmet equipped with a flip-down viewing monocle and taps into the cockpit's digital display -- may seem like something that belongs in Battlestar … Read more

You'd think a ship designed after a baseball bat would go over like a foul ball when it comes to seaworthiness, but research ship FLIP has been a hit since its launch 50 years ago.

The bizarre research vessel can go from a horizontal to vertical position while staying afloat and stable in heavy seas, even in 80-foot waves. That allows it to perform oceanographic research measurements with great accuracy.

"A ship rolls with storm waves, but FLIP is so stable it is almost immobile," Scripps Institute of Oceanography engineer Eric Slater has said in recalling FLIP riding out a hurricane. "Waves hit it like a brick wall. We were literally thrown out of our chairs inside FLIP when the big waves hit."

Operated by Scripps and owned by the U.S. Navy, the 355-foot FLIP was designed by Phillip Rudnick, Fred H. Fisher, and Fred N. Spiess, and first tested in July 1962 as part of an anti-submarine rocket program. It was recently shown off in the Pacific for its birthday. … Read more

President Barack Obama has been fighting a clandestine cyberwar against foreign governments and al-Qaeda, and his efforts in that arena have far exceeded those of his predecessors, according to a new report.

The New York Times today published a wide-ranging report, adapted from an upcoming book, "Confront and Conceal: Obama's Secret Wars and Surprising Use of American Power," by Times reporter David Sanger, on the Obama administration's use of cyberwarfare to take on Iran and potentially other countries or entities it views as a threat. Chief among the administration's targets was Iran's nuclear plants, … Read more

The Flame worm has put the Middle East and neighboring regions on high alert and caused several security experts to look for the source. And although some media reports have linked Israel to the attack, the country has denied all involvement.

The trouble for Israel started recently when the country's vice prime minister, Moshe Ya'alon, said on Israel's military radio station, Army Radio, that "there are quite a few governments in the West that have rich high-tech [capabilities] that view Iran, and particularly the Iranian nuclear threat, as a meaningful threat -- and can possibly be … Read more
