Researchers from University of Lausanne and EPFL University in Switzerland have developed genetically altered mice that have far higher physical endurance than regular mice. These "mighty mice" are able to run almost 50 percent further and for 20 minutes longer, while looking no different than their unaltered cousins, save for slightly larger muscles.
A bipedal robot developed at the University of Michigan can run with a human-like gait, the fastest-ever robot with knees. Feedback algorithms are helping Mabel, a headless robot with impressive gams, to keep its balance as it runs in a round pen.
Oscar Pistorius of South Africa just qualified for the 400-meter and the 4x400-meter relay races at this year's World Championships, his first trip there. That's an amazing feat in itself, but made more amazing as Pistorius is a double amputee, using two carbon-fiber Cheetah prosthetic legs to run. He'll be the first-ever amputee athlete to perform at the event.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
