Biomedical engineers are unveiling a new type of fabric that, much like human skin, can turn excess sweat into droplets that simply fall away on their own accord.

"We intentionally did not use any fancy microfabrication techniques so it is compatible with the textile manufacturing process and very easy to scale up," said Siyuan Xing in a school news release. Xing is the lead biomedical engineering student on the project at the University of California, Davis.

An article in the journal Lab on a Chip describes the fabric's microfluidic platform. Multiple woven threads suck droplets of water … Read more

Unlike Acoustic Kitty, the U.S. military's dolphin program, active since the 1960s, has had quite a bit of success. Dolphins, you see, are capable of producing sonar, and have an aptitude for learning commands, proving to be much more useful than machines for aquatic mine detection.

"Dolphins naturally possess the most sophisticated sonar known to man," explains Braden Duryee, operations supervisor for the SSC Pacific Biosciences Division. "They can detect mines and other potentially dangerous objects on the ocean floor that are acoustically difficult targets to detect."

This time, though, two of the trained bottle-nose dolphins have discovered something much more interesting than mines off the coast of Coronado, Calif: a late 19th century Howell Automobile Torpedo, the first self-propelled torpedo in the U.S. … Read more

A Texas man has become the first person to successfully fire a real bullet from a gun created on a home 3D printer. Sound crazy? In fact, the blueprint for the pistol is available for free online for anyone to access. And it's legal.

University of Texas law student Cody Wilson, 25, released a video of a 3D-printed gun named the "Liberator" taking test shots over the weekend. The gun is mostly made of plastic, with the exception of two metal pieces: a metal firing pin and a 6-ounce piece of steel that's required by law under the Undetectable Firearms Act. Of course, the piece of steel that makes the weapon visible to metal detectors, and legal, can certainly be omitted by future hobbyists.

Wilson invited Forbes reporter Andy Greenberg to witness the trial. Greenberg reports that 15 of the gun's 16 pieces were printed by a Stratasys Dimension SST 3D printer -- the metal firing pin is the 16th piece. … Read more

Mimicking the human grasp is no easy feat. Robotic hands tend to be clunky and expensive.

But now, the Defense Advanced Research Projects Agency is showing off a robotic hand that's dexterous enough to pick up keys and tough enough to survive being hit with a baseball bat.

The video below shows a prototype from DARPA's Autonomous Robotic Manipulation project. Instead of trying to reproduce the human hand in robot form, the prototype focuses on function. It has three fingers that are able to pick up small objects such as keys and credit cards, and it can even grasp objects with tweezers. … Read more

If the apparel oft proclaims the man, as Polonius said in "Hamlet," then the camo suit proclaims the robot.

Boston Dynamics is showing off new duds for its Petman humanoid robot platform, and it looks rather badass.

Peman is a walking, squatting, flexing hazmat suit testing machine. It's designed to stand up to chemical warfare agents.

With nothing on, it looks like The Terminator. But when it's wearing this camouflage chemical suit and gas mask, you could mistake it for a real soldier. … Read more

In the future, the U.S. Army could rely on low-cost ambidextrous autonomous robots, instead of bomb disposal technicians or remote control robots, to defuse improvised explosive devices. Better yet, activating and operating the smart robots may only require a nearby solider to say, "Go find and defuse the bomb."

As a precursor to that end goal, DARPA's Autonomous Robotic Manipulation program released a video that shows a robot changing a tire by itself. The robot, complete with a camera and an array of sensors, successfully uses two hands (one equipped with a drill) to remove a tire and put a new one in its place. A small screen shows the robot's virtual view of the tire, which reveals how software algorithms detect each the scene and its minute details in real time.… Read more

"We're gonna need a bigger jellyfish." I imagine that's what the Navy and researchers at Virginia Tech were thinking when they started development on Cyro, a robot jellyfish that is 5 foot 7 inches across and weighs a hefty 170 pounds.

The Navy has been into robot jellyfish before, but none have been on this scale for sheer size. This big boy is a much larger version of an earlier robot called the Robojelly, which was only about as large as a hand.… Read more

Looks like someone in the New York City area needs to keep their robot plane on a shorter leash.

Federal authorities are investigating today after the pilot of an Alitalia flight spotted what appeared to be a small, unmanned drone hovering close by as the passenger flight made its approach in to New York's JFK airport on Monday afternoon. The drone reportedly came within 200 feet of the jet.

Don't get all panicky over the prospect of a possible al Qaeda sleeper cell in Queens though. The eyewitness said the drone was black in color, no more than 3 feet wide, and had four propellers -- a description much more similar to a Parrot drone than a Predator.… Read more

The last time we checked in on Boston Dynamics, its "robot bison" was busy demonstrating what it could do out in the field. And we were impressed.

Today we get to see a different kind of robot animal in action. I'll give you a hint on the type: fetch!

Awww... who's a good boy? The robot on display in the video is BigDog, a DARPA-funded all-terrain cyber-canine meant for military use. It can tackle slopes up to 35 degrees, rubble, snow, mud, and water, and can carry a 340-pound load. Boston Dynamics writes of the monster dog's latest trick: … Read more
