Robotic, Department-of-Defense funded, and power performance enhanced — high-tech replacement limbs make for great photos and video clips. And the people who wear them — often veterans, or well-off patients going through an inspirational recovery after an eye-popping accident — make for great media storytelling. But those stories don't represent the vast majority of amputees, writes Rose Eveleth at NOVA Next, and the high-tech prosthetics that get all the attention aren't always the best option to meet everyday needs.
In one study that explored the needs of amputee farmers, the researchers interviewed a man who was given a myoelectric arm—something that is not only expensive, but also completely unsuited for farm work. Myoelectric devices cannot get wet or dirty, two things that are nearly guaranteed during a day of farming. The farmer in question simply kept the arm in his closet—a $100,000 device sitting there gathering dust.Radocy’s body-powered hand can outperform even the most advanced myoelectric hands. It’s not just farmers for whom specialty electric devices aren’t quite right either. When it comes to everyday users, myoelectric arms or microprocessor knees, for all their amazing technology, are sometimes not the best option. Radocy, an upper limb amputee, is an advocate for what are called body-powered prostheses. Rather than being controlled by a computer or sensors, a body-powered arm is far more like a series of bicycle brakes—the arm is strapped to the users body, and connected to a series of cables. By twisting his body one way or another, Radocy can open and close his hand. The system may seem low-tech, but Radocy argues that when it comes to performance, his body-powered hand can outperform even the most advanced myoelectric hands.
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]

3D printers are hot, but they’re also pricey. While the prospect of cranking out everything we can dream up is enticing, cost is often one factor that keeps us from jumping onto the 3D printing train.Now, thanks to M3D, that doesn’t have to be the case. You can now get its flagship 3D printer–plus four reels of filaments–for just […]
It’s no secret that technology is changing the way we all work—but it’s also transforming the way we play. The games of today look nothing like those of 10 or even 20 years ago: these days it’s all about mobile and 3D. And now you can learn to design 3D mobile games with the Intro to Unity 3D Game […]
