Cool invention helps tired players bounce back

"Players for the San Francisco 49ers trotted off the field during Sunday's game against the Detroit Lions and grabbed for the requisite towels and Gatorade. A few went for something else on the bench, slipping their hands into a coffee-pot-like contraption that stops cramping and overheating. The device, called the Glove and invented by two Stanford biologists, is used by the Niners during games and at practice for players' health. But its applications are far broader: from treating stroke and heart attack victims to allowing soldiers to remain in the field longer under intense heat" - SFGate
