The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.

The patient is an unnamed man in his 20s living in Rome who lost the lower part of his arm following an accident, said Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland.

The wiring of his new bionic hand will be connected to the patient’s nervous system with the hope that the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors.

Dr Micera said that the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves.

This should allow the man to control the hand by his thoughts, as well as receiving sensory signals to his brain from the hand’s sensors. It will effectively provide a fast, bidirectional flow of information between the man’s nervous system and the prosthetic hand.

“This is real progress, real hope for amputees. It will be the first prosthetic that will provide real-time sensory feedback for grasping,” Dr Micera said.

“It is clear that the more sensory feeling an amputee has, the more likely you will get full acceptance of that limb,” he told the American Association for the Advancement of Science meeting in Boston.

“We could be on the cusp of providing new and more effective clinical solutions to amputees in the next year,” he said.

An earlier, portable model of the hand was temporarily attached to Pierpaolo Petruzziello in 2009, who lost half his arm in a car accident. He was able to move the bionic hand’s fingers, clench them into a fist and hold objects. He said that he could feel the sensation of needles pricked into the hand’s palm.

However, this earlier version of the hand had only two sensory zones whereas the latest prototype will send sensory signals back from all the fingertips, as well as the palm and the wrists to give a near life-like feeling in the limb, Dr Micera said.

“The idea would be that it could deliver two or more sensations. You could have a pinch and receive information from three fingers, or feel movement in the hand and wrist,” Dr Micera said.

“We have refined the interface [connecting the hand to the patient], so we hope to see much more detailed movement and control of the hand,” he told the meeting.

The plan is for the patient to wear the bionic hand for a month to see how he adapts to the artificial limb. If all goes well, a full working model will be ready for testing within two years, Dr Micera said.

One of the unresolved issues is whether patients will be able to tolerate having such a limb attached to them all the time, or whether they would need to remove it periodically to give them a rest.

Another problem is how to conceal the wiring under the patient’s skin to make them less obtrusive. The electrodes of the prototype hand to be fitted later this year will be inserted through the skin rather than underneath it but there are plans under development to place the wiring subcutaneously, Dr Micera said.

Sony Announces the PlayStation 4

PlayStation fans, your wait is almost over. Sony officially announced the PlayStation 4 at a press event Wednesday, the next generation of its popular console.

Nine years in the making, the PlayStation 3, the current PlayStation in the market, was released seven years ago in November of 2006.

“The living room is no longer the center of the PlayStation universe, the gamer is,” Andrew House, CEO of Sony Computer Entertainment said at the event. “We believe that PlayStation 4 represents a shift from thinking of a box or console.”

PlayStation 4′s lead system architect Mark Cerny said that Sony started working on the console shortly after the release of the PlayStation 3, ultimately creating a console “for developers, by developers.” The console sports a completely updated UI, and a number of new features ranging from an updated controller to social features you won’t find on any other console.

3D Printing Pen Lets You Draw Sculptures in Midair

We know you’ve had that childhood dream: You spent hours in your room conjuring up doodles, wishing you could take them right off the page. Who doesn’t imagine waving a hand to make their creation magically appear in thin air?

The advent of 3D printing introduced the convenience of quickly making designs a reality, and one company is bringing this creative ease to your fingertips. 3Doodler, dubbed the “world’s first 3D printing pen,” lets you draw three-dimensional structures in midair.

Toy and robotics company WobbleWorks created the pen to make 3D printing affordable and accessible. While most 3D printers can cost you thousands of dollars, 3Doodler is available for preorder on Kickstarter for $75.

“If you can scribble, trace or wave a finger in the air you can use a 3Doodler,” the designers say on their site.

The pen uses ABS plastic, the same material found in many 3D printers. You can start free-form drawing in the air or draw on surfaces to create flat objects for stacking and connecting. Check out the video, below, to see how it works.

Google unveiled a groundbreaking new Chromebook laptop Thursday — one with touchscreen capability, powerful chipset and an extremely high-resolution display.

The Chromebook Pixel, available for order on the Google Play store and shipping in April, features a 12.85-inch touch-sensitive Gorilla Glass screen. The resolution is 4.3 million pixels, which works out to 239 pixels per inch. (The average Windows laptop has about half that; technically, it also beats the Macbook Retina.)

The Pixel will come in two versions, both boasting an Intel Core i5 processor. The basic model is Wi-Fi only; a more expensive model has the ability to connect to Verizon’s superfast LTE network. Google claims a battery life of five hours on the device, which has QuickOffice built into the browser and an SD card slot for automatic photo uploads to Google+. Those features can also be used offline (uploads queued for later, of course).

The price, however, is relatively steep: $1,299 for the Wi-Fi only version, $1,449 for the LTE model.

Google was careful to emphasize that the Pixel isn’t for everyone. “This is for power users who live in the cloud,” Senior Vice President of Chrome Sundar Pichai repeatedly told a select group of journalists at a low-key launch event in San Francisco.

Having a touchscreen doesn’t mean that Google plans to integrate its mobile OS, Android, into the device. But Pichai hoped web developers would start making their interfaces touch-sensitive — so that content on the device would be indistinguishable from Android.

“Touch is here to stay, and I’m pretty sure every laptop will have touch in the future,” Pichai said. “Using a laptop with touch seems strange at first, but your day-to-day browser experience starts changing. In our tests, users started replacing the touchpad pretty quickly.”

The aluminum-coated Pixel was designed and built by Google, with help from other unnamed PC manufacturers. Plenty of thought appears to have gone into the design: For example, there’s an extra microphone under the keyboard, complementing the two mics next to the camera, allowing the software to cancel out any noise you might make while typing on a video conference.

“Our goal was to have the hardware disappear,” Pichai added.

HP announces Slate 7: the company’s first Android tablet.

As you’d expect from the name, the Slate 7 is a seven-inch tablet which runs Android 4.1 Jelly Bean. Under the handsome soft-touch rubber exterior, you’ll find a dual-core 1.6GHz ARM Cortex-A9 chip of an undisclosed variety powering a 1024 x 600 resolution FFS+ LCD touchscreen display, which HP says will boast wide viewing angles and perform well in low light. There’s 1GB of RAM, 8GB of solid state storage (expandable via microSD), 802.11 b/g/n Wi-Fi, Bluetooth 2.1, and a pair of cameras, with one front-facing VGA webcam and a 3-megapixel rear imager. There’s also a set of stereo speakers, with Beats Audio processing to give them a little extra oomph, and all of that fits in a stainless steel frame that’s 10.7mm thick and weighs about eight-tenths of a pound. HP says the battery is good for five hours of video playback.

Courtesy – is a non-profit foundation dedicated to growing computer programming education. Their goals include:

1. Spreading the word that there is a worldwide shortage of computer programmers, and that it’s much easier to learn to program than you think.
2. Building an authoritative database of all programming schools, whether they are online courses, brick+mortar schools or summer camps.

Their vision is that every student in every school has the opportunity to learn how to code. They believe computer science and computer programming should be part of the core curriculum in education, alongside other science, technology, engineering, and mathematics (STEM) courses, such as biology, physics, chemistry and algebra.
