Rotary Mechanical Smartphone combines vintage rotary dial and modern technology

Rotary Mechanical Smartphone combines vintage rotary dial and modern technology: "Created by New Zealand-based designer Richard Clarkson, the Rotary Mechanical Smartphone is a one-of-a-kind device that has all the features of a regular smartphone, but it resembles a vintage rotary dial telephone. It represents an attempt at combining digital technologies and physical, mechanical systems, thus making cutting edge technology more tangible."

Implant could wirelessly relay brain signals to paralyzed limbs

Implant could wirelessly relay brain signals to paralyzed limbs: "For a great number of people with paralyzed limbs, the reason that they can't move the arm or leg in question is because the 'move' command isn't able to reach from their brain to the limb. This is often due to damage to the nervous system, or to the brain, although the limb itself is still perfectly functional ... so it could still move, if only there was a way of getting the signal to it. Well, one might be on its way."
