A vibrating glove could help steady the hands of patients suffering from tremors caused by conditions like Parkinson's disease, said Matt McFarland at The Washington Post. The GyroGlove uses a rapidly spinning bronze disc on the back of the hand, weighing about as much as a roll of nickels and moving at up to 20,000 rotations per minute, to provide a steadying force. The effect "is akin to putting one's hand in molasses," naturally filtering out the wearer's shaking. GyroGear — the London-based startup that makes the glove — says it was able to reduce tremors by 90 percent in one test.
