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.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
Despite Trump’s denial of climate change the the ghastly attacks on climate science and mitigation in the new proposed budget, the Carbon Bubble — which overprices hydrocarbons and the industries that rely on them, as though we’ll be burning all of them with impunity — is about to pop.
South American polka dot tree frogs are pretty cool, but Julián Faivovich and Carlos Taboada found out they are even cooler when an ultraviolet flashlight is trained on them. They fluoresce. Many animals can see beyond the spectrum visible to humans, and these frogs adapted with this trait. From the abstract: Fluorescence, the absorption of […]
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
