Cutting Edge

Leap Motion has struck a deal with Hewlett-Packard to bundle and embed its 3D motion control technology in some of the computer giant's devices.

The San Francisco startup's gesture-control system measures users' movements to an accuracy of a hundredth of a millimeter. It plans to release the technology in mid-May, charging $80 for a small thumb drive-size device that plugs into a computer's USB port.

Already, Leap Motion had cemented deals to bundle its controller with Asus PCs, and to sell it in Best Buy stores and at Bestbuy.com, as well as on its own Web … Read more

At some point in the not-too-distant future, the skies could be filled with drones -- swarms of insect-size and larger drones hovering over neighborhoods, alleyways, and even inside bedrooms.

That's a nightmare future, according to Google's Eric Schmidt. In an interview with the Guardian, he said. "You're having a dispute with your neighbor. How would you feel if your neighbor went over and bought a commercial observation drone that they can launch from their backyard? It just flies over your house all day. How would you feel about it?"

Following the proliferation of mini-drones, someone … Read more

There just aren't enough donated organs to fill the need. That's why scientists have been dreaming of growing transplantable organs in labs. Scientists at the Massachusetts General Hospital Center for Regenerative Medicine have made a step forward by creating a functional rat kidney.

The process is not quite as futuristic as growing a whole organ from scratch. Researchers started with kidneys from dead rats and used a special soap-cleaning process to scrub away the cells. Essentially, this gave them a foundation of a kidney to work with, a blank canvas.… Read more

If you love eye-popping images of space, here's welcome news: the Hawaiian Board of Land and Natural Resources has backed building what's to be the world's largest, most powerful optical telescope above the clouds atop the volcano Mauna Kea.

The Thirty Meter Telescope (TMT) will have a primary mirror of 492 segments measuring some 100 feet across, giving it the power to image objects 13 billion light years away, near the beginning of the universe.

It may also photograph planets outside our solar system with unprecedented detail. … Read more

It's mission accomplished for the experimental X-48C aircraft.

The distinctively shaped machine this week made the last of 30 flights in an eight-month program as backers Boeing and NASA sought to show how well a "blended wing body" aircraft can perform. The X-48C program is tied to NASA's Environmentally Responsible Aircraft project, which is geared toward developing futuristic airplanes that burn less fuel, spew fewer emissions, and make less noise.

The Boeing-designed X-48C has a radically different look than that of conventional aircraft. Where a big 747 or a little Cessna has -- very roughly speaking … Read more

It's hard to imagine life without a limb -- not just the physical difficulties, but how it might affect your relationship with your body, and your sense of how you're perceived by the world around you. One prosthetist is taking into account not just restoring limb function, but also the wearer's personality and style.

The Alternative Limb Project is the work of Sophie de Oliveira Barata, who, taking her honors degree from the London Arts University studying special-effects prosthetics, went to work as a sculptor for a prosthetics company. In her eight years there, she created realistic limbs and digits for amputees who wanted their new limbs to blend into their bodies.

de Oliveira Barata has continued this work with the Alternative Limb Project, and her realistic limbs, molded from casts of the customer's own body, are incredibly detailed. But some people prefer to stand out in a crowd. … Read more

In a quest to learn what leads some people to turn to Facebook to connect with others, doctoral student Russell Clayton of the Missouri School of Journalism found that anxiety and alcohol use seem to play a big role.

For his master's thesis, which appears in the May issue of Computers in Human Behavior, Clayton surveyed more than 225 college freshman about two emotions, anxiety and loneliness, and two behaviors, alcohol and marijuana use. He found that the students who reported both higher levels of anxiety and greater alcohol use also appeared the most emotionally connected with Facebook. Those … Read more

Uber announced today that it plans to start ridesharing services where other companies, like Lyft and Sidecar, have already tested the waters.

"We've basically really shied away from it because in most cities there are pretty stiff citations, as well as, the potential for a criminal misdemeanor," CEO Travis Kalanick said during a press conference call.

The company emphasized that this was only a policy change and that it has not yet set dates for when it will start rolling out these services. Uber operates in 30 cities and the new ridesharing service would be a cheaper … Read more

There's long been speculation and research about algae's potential as a power source. The fast-growing plants waste three-quarters of the sunlight they absorb, so what if that energy could be captured and converted?

That's the premise behind BIQ House, designed by architectural firm Splitterwerk. It's a new algae-powered building that's opening on April 25 as part of the International Building Exhibition (IBA) in Hamburg, Germany. The building's east and south facades are covered in a system of louvres. Filled with microalgae, these louvres form 200 square meters of panels to power the building. … Read more
