Springing ahead of nature: Device increases walking efficiency

April 1, 2015 2:10 pm | by North Carolina State University | Comments

It's taken millions of years for humans to perfect the art of walking. But research results published today in the journal Nature show that humans can get better 'gas mileage' using an unpowered exoskeleton to modify the structure of their ankles. The device puts an extra spring ...

Light-powered gyroscope is world's smallest

April 1, 2015 2:05 pm | by The Optical Society | Comments
