The world's first bionic hand that will allow patients to 'feel' sensations set to be transplanted onto a patient Will give amputees a genuine sense of touchAttached directly to the nervous system via electrodes'We hope one day the user will just forget it's there' Dr Silvestro Micera By Nick Mcdermott, Science Reporter Published: 18:34 GMT, 17 February 2013 | Updated: 08:21 GMT, 18 February 2013 A bionic hand which allows the recipient to feel ‘lifelike’ sensations is to be transplanted on to a patient’s arm for the first time. Until now, artificial limbs have been able to pick up brain signals destined for the absent hand and translate them into movements, but they could not give sensory feedback. The new hand, which is attached directly to the nervous system via electrodes clipped on to two of the arm’s main nerves, aims to restore a sense of touch in amputees. Scientists hope the new bionic hand will prove to be a breakthrough in the development of artificial limbs The bionic hand is attached directly to the central nervous system meaning it can be controlled directly by the recipient
Dreaming of Flying | Quite Curious I h ad one of those flying dreams, the kind that we all have at one point or another. This one though, felt particularly special, and I felt the need to record it somehow. My photo turned out much better than I thought it would. An old man saw me editing this photo at Starbucks and took great interest in it since he was a pilot, and curious about anything that flew. How I Did It I wasn’t going to show anyone the un-edited photos to keep up the story that I was a flying superhero, but I’ve been asked “How did you do that?” This weekend I threw a ladder, chair, and some other odds and ends into the car, and went out scouting for a location buy discount viagra for the shoot. Here’s the original, un-edited photo. I actually left the shoot feeling dejected, because I didn’t think I would get anything usable. First of all ,jumping on couch cushions is scary as hell, because there’s a good chance that you’ll either fall on the concrete, or land through the cushion cracks. Photoshop Trickery
3D solar panels can produce 20 times more energy than flat panels We see the trend in 3D technology everywhere: Movie theaters, home theaters, game consoles, 3D printers. But researchers at Massachusetts Institute of Technology recently discovered that creating a 3D-inspired solar panel not only help to keep up with the trends, it could draw in 20 times more energy than flat panel designs. Traditional solar panels lay flat on a surface or rooftop, facing the sun to collect energy. “I think this concept could become an important part of the future of photovoltaics,” said Jeffrey Grossman, the Carl Richard Soderberg Career Development Associate Professor of Power Engineering at MIT and one of the project’s leaders. The accordion-style arrays also work better because they receive solar energy from all angles rather than in just one direction. Researchers also say the tower style panel helps save space by standing vertically, and the design will be easier to manufacture than the cubes.
