Gravity may be woven into the very fabric of space-time, but some objects seem nearly immune to its pull.

Stretchable Artificial Nerves Help Restore Motion in Mice

New neuroprosthetic approach is more flexible and less power-hungry than other designs

Conventional neuroprosthetic devices that aim to help patients bypass nerve damage are often rigid and power-hungry. Now scientists have developed stretchable artificial nerves that helped paralyzed mice run on a treadmill and kick a ball while consuming less than one-hundredth of the power of a typical microprocessor. The scientists suggest these artificial nerves may one day find use in the human body.

To help restore movement to patients who have suffered nerve damage from injuries or diseases, scientists are researching neuroprosthetic devices that can help relay signals from the brain to muscles or nerves. However, these systems often face a number of critical limitations, says study co-senior author Tae-Woo Lee, a materials scientist at Seoul National University.

Xiaomi, a large Chinese consumer electronics manufacturer, has introduced a full size bipedal humanoid robot called CyberOne. It’s 177 centimeters in height and weighs 52 kilograms, and it comes with 21 degrees of freedom, with “a curved OLED module to display real-time interactive information.” Nifty! So, uh, its actual purpose is... what exactly?
