How listening to random sound can unlock a trapped mind

LOS ANGELES – David Tobin took to the stage at a recent technology conference in downtown Los Angeles, asked the 500 attendees to close their eyes, and turned up the sound so they could sample his wares: a textured, layered soundscape that he calls an "audiojack."

A thousand eyes clamped shut as they collectively heard a ball thudding into a ...Read more

The work, published as a trio of papers Thursday in Science, sheds new light on the often murky story of when...Read more

By vibrating the muscles, engineers produce a better prosthetic hand

Consider for a moment the welter of unconscious judgments and adjustments you make every time your hand reaches for an object -- say, a tall drink of water. Eyes, muscles, brain and digits coordinate with exquisite speed and subtlety to ensure the cup is reached, grasped around the middle, held gently but firmly, and drawn -- upright and at a ...Read more
