3D-print your own invisibility cloak, kind of

While we remain dubious about the legitimacy of using the word "invisible" when visible light isn't involved, that's what a team of engineers at Duke University have dubbed their creation. Seven years ago, they demonstrated their first "invisibility cloak" in a laboratory; now, thanks to 3D printing, the fabrication process is a lot more accessible.

The object -- which looks more like a Frisbee made of Swiss cheese than a wearable cape a la Harry Potter -- has a large hole in the center, with seemingly random holes in the disc. The size, shape, and placement of these holes have actually been determined using algorithms to disguise any object placed in the center hole from microwave beams aimed through the side of the disc, making it appear as though the object isn't there. … Read more

Tesla eyes 'autopilot' partnership with Google

Tesla, the electric car maker, has been in talks with Google about the development of a self-driving car, the former's CEO revealed Tuesday.

In a Bloomberg interview, Tesla CEO Elon Musk said that his company has "had some technical discussions with Google" about the search giant's self-driving car technology. However, he pointed out that the technology that Google uses, which is based on laser sensors to detect what's around, is too expensive to be feasible anytime soon.

Instead, Musk told Bloomberg, he'd like to see a camera-based system that "sees" what's … Read more

Glasses and Glass: How Google Glass changed my face

I had two transformative yet very minor optical experiences last week, both kicking off in the space of 2 hours: I got contact lenses, and I began experimenting with Google Glass.

The two are interlinked, because I couldn't use Google's bleeding-edge wearable tech with my comfy Ray-Ban eyeglasses.

If I was going to use Glass, I'd need contacts.… Read more

3D-printed 'Liberator' gun fires first successful shot

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

Terrafugia to develop vertical takeoff flying car

Frustrated commuters may soon get some good news from Terrafugia, the maker of the Transition flying car.

The company on Sunday said it has begun feasibility studies of a four-seat, vertical takeoff and landing plug-in hybrid-electric flying car, the TF-X. The vehicle will "further increase the safety, simplicity, and convenience of personal aviation" by using state-of-the-art intelligent systems and other technology, Terrafugia said.

"This is the right time for us to begin thinking about the future of the company beyond Transition development," Carl Dietrich, Terrafugia's chief executive and chief technology officer, said in a press … Read more

NASA wants to send your best haiku... to Mars

For its trip to Mars, NASA wants haikus like this, Why? Because it's cool.

That's pretty much the gist of this whole story, actually. Maybe I should start composing all stories in the form of a haiku to save us all time.

It's no joke, though, that NASA really is collecting submissions of three-line poems from the public to send into space aboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, which will launch later this year for a mission to study the Red Planet's atmosphere.… Read more

World's first 3D-printed gun makes its debut

Many believe that the future of printing is in 3D, which enables companies and even novices to design whatever they want and "print" it into a real-world device.

Now, a group has a proof-of-concept that such a dream could be a reality. Only this device is a gun.

Defense Distributed, a Texas-based group working toward nonprofit status, has given Forbes images of what is being called the world's first 3D-printed handgun. The gun is capable of firing standard handgun rounds and is made entirely of plastic, except for a nail that's being used as a firing … Read more

Printable bionic ear sends hearing to the dogs

Using off-the-shelf 3D printing tools, silver nanoparticles, and cell culture, scientists at Princeton University have created a functional bionic ear that can detect radio frequencies far beyond the normal human range.

Living, 3D-printed tissue has been in the news a fair bit recently, but this is the first attempt at creating a fully functional organ with embedded electronics.

"In general, there are mechanical and thermal challenges with interfacing electronic materials with biological materials," said Michael McAlpine, an assistant professor of mechanical and aerospace engineering at Princeton and the lead researcher on the project. "Previously, researchers have suggested some strategies to tailor the electronics so that this merger is less awkward. That typically happens between a 2D sheet of electronics and a surface of the tissue. However, our work suggests a new approach -- to build and grow the biology up with the electronics synergistically and in a 3D interwoven format." … Read more
