A sensational breakthrough: the first bionic hand that can feel - News - Gadgets & Tech
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. “The idea would be that it could deliver two or more sensations.

World premiere of muscle and nerve controlled arm prosthesis A surgical team led by Dr Rickard Brånemark, Sahlgrenska University Hospital, has carried out the first operation of its kind, where neuromuscular electrodes have been permanently implanted in an amputee. The operation was possible thanks to new advanced technology developed by Max Ortiz Catalan, supervised by Rickard Brånemark at Sahlgrenska University Hospital and Bo Håkansson at Chalmers University of Technology. “The new technology is a major breakthrough that has many advantages over current technology, which provides very limited functionality to patients with missing limbs,” says Rickard Brånemark. Big challengesThere have been two major issues on the advancement of robotic prostheses: 1) how to firmly attach an artificial limb to the human body; 2) how to intuitively and efficiently control the prosthesis in order to be truly useful and regain lost functionality.

Microsoft’s Perceptive Pixel premise: The future of touch computing isn’t stuck in your pocket When Microsoft purchased the Perceptive Pixel company, maker of 55 and 82 inch touchscreen displays that go by the eponymous acronym PPI, what it intended to do with the firm wasn’t completely clear. At the time, Microsoft stated the following: The acquisition of PPI allows us to draw on our complementary strengths, and we’re excited to accelerate this market evolution [...] PPI’s large touch displays, when combined with hardware from our OEMs, will become powerful Windows 8-based PCs and open new possibilities for productivity and collaboration. For more context, here’s how TNW reported Microsoft CEO Steve Ballmer’s announcement of the purchase:

Man With Severed Spinal Cord Walks Again After Cell Transplant A man paralyzed for two years is now walking again, albeit with a frame, after a transplant to his spine. The treatment, to be published in this month's Cell Transplantation, has been under discussion for a while, but has only now shown success. In 2010, Darek Fidyka was repeatedly stabbed, rendering him paralyzed from the chest down. Fortunately, however, his nose was unscathed. Olfactory ensheathing glia (OEGs) surround olfactory axons, the nerve fibers that conduct electrical charges from the nose to the brain to allow us to smell.

Biotech Breakthrough: Monkeys can feel virtual objects using a brain implant As long as they figure out which areas to stimulate those problems can be solved with neuro-optics. It works by inserting a gene into the target neurons that makes them fire when exposed to a specific frequency of light. So instead of having to physically insert pieces of metal into the brain they place small laser diodes on the outside of the brain and fire them through the intervening tissue without actually harming it. Since no parts of the device is in direct contact with the brain it can be replaced, or upgraded, without worrying about permanently damage to the brain itself.

txchnologist February 19th, 2013 | by Charles Q. Choi Temporary electronic tattoos could soon help people fly drones with only thought and talk seemingly telepathically without speech over smartphones, researchers say. Commanding machines using the brain is no longer the stuff of science fiction. In recent years, brain implants have enabled people to control robotics using only their minds, raising the prospect that one day patients could overcome disabilities using bionic limbs or mechanical exoskeletons. But brain implants are invasive technologies, probably of use only to people in medical need of them.

A New Flexible Keyboard Features Clickable Buttons A very thin keyboard that uses shape-changing polymers to replicate the feel and sound of chunky, clicking buttons could be in laptops and ultrabooks next year. Strategic Polymers Sciences, the San Francisco-based company that developed the keyboard, is working on transparent coatings that would enable this feature in touch screens. Today’s portable electronics provide rudimentary tactile feedback—many cell phones can vibrate to confirm that the user has pressed a button on a touch screen, for example. These vibrations are produced by a small motor, meaning the entire phone will move rather than just the appropriate spot on the screen where the button is, and there can be a lag in response time. “It’s amazing how fast software has grown to compensate for problems with touch screens—and sometimes you still text a word that’s the opposite of what you mean,” says Christophe Ramstein, CEO of Strategic Polymers.

How to regenerate axons to recover from spinal-cord injury HKUST researchers cut mouse corticospinal tract axons (labeled red). A year later, they deleted the Pten gene in the experimental group (bottom) but not the control group. The Pten gene removal resulted in axon regrowth in seven months, unlike the control group (top).

It is the first "mind reading" technology to create such images from scratch, rather than picking them out from a pool of possible images. Earlier this year Jack Gallant and colleagues at the University of California, Berkeley, showed that they could tell which of a set of images someone was looking at from a brain scan. To do this, they created software that compared the subject's brain activity while looking at an image with that captured while they were looking at "training" photographs.
