A team in China figured out a way to take control of a rat and “steer” it through a maze with their thoughts.

Recently University of Glasgow developed a Graphene based E-Skin for prosthetic limbs. The research started with making a prosthetic arm that could sense even the minutest of pressure for gripping soft objects. It eventually yielded a prosthetic limb that was also self powering.

This was because of the development of Graphene based supercapacitors.

Researchers have developed a next-generation bionic hand that allows amputees to regain their proprioception. The results of the study, which have been published in Science Robotics, are the culmination of ten years of robotics research.

The next-generation bionic hand, developed by researchers from EPFL, the Sant’Anna School of Advanced Studies in Pisa and the A. Gemelli University Polyclinic in Rome, enables amputees to regain a very subtle, close-to-natural sense of touch. The scientists managed to reproduce the feeling of proprioception, which is our brain’s capacity to instantly and accurately sense the position of our limbs during and after movement – even in the dark or with our eyes closed.

The new device allows patients to reach out for an object on a table and to ascertain an item’s consistency, shape, position and size without having to look at it. The prosthesis has been successfully tested on several patients and works by stimulating the nerves in the amputee’s stump. The nerves can then provide sensory feedback to the patients in real time – almost like they do in a natural hand.

Soft, squishy, ancient spiders are hard to investigate — they don’t fossilise as easily as bones or exoskeletons. So you can imagine how excited researchers were to find 10 brand new spider fossils in a relatively unexplored area called the Jinju Formation.

The Jinju Formation is a geological area of South Korea from the Mesozoic era, between 252 and 66 million years ago. This new spate of fossils, which researchers from the Korea Polar Research Institute and the University of Kansas found in shale, has increased the number of known spiders in the Jinju Formation from just one to a whopping 11.

But two of these spider finds were even more exciting than the rest – their eyes still reflected light 110 million years after they died.

Lighter than air! Stronger than steel! More flexible than rubber! No, it’s not an upcoming superhero flick: It’s the latest marvelous formulation of carbon nanotubes–at least as reported by the creators of the new super-material. Researchers working on artificial muscles say they’ve created nanotech ribbons that make our human muscles look puny by comparison. The ribbons, which are made of long, entangled 11-nanometer-thick nanotubes, can stretch to more than three times their normal width but are stiffer and stronger than steel… They can expand and contract thousands of times and withstand temperatures ranging from −190 to over 1,600 °C. What’s more, they are almost as light as air, and are transparent, conductive, and flexible [Technology Review].

The material is made from bundles of vertically aligned nanotubes that respond directly to electricity. Lengthwise, the muscle can expand and contract with tremendous speed; from side-to-side, it’s super-stiff. Its possibilities may only be limited by the imaginations of engineers. [The material’s composition] “is akin to having diamond-like behavior in one direction, and rubber-like behavior in the others” [Wired], says material scientist John Madden, who wasn’t involved in the research.

When voltage is applied to the material, the nanotubes become charged and push each other away, causing the material to expand at a rate of 37,000 percent per second, tripling its width. That’s 10 times as far and 1000 times as fast as natural muscle can move, and the material does so while generating 30 times as much force as a natural muscle [IEEE Spectrum]. The researchers put together a video to illustrate the concept, and will publish their work in Science tomorrow.

We strongly believe that only digital health can bring healthcare into the 21st century and make patients the point-of-care.

Patients and doctors have been waiting for this device for decades.
