Good news for the cyborgs in the crowd: the ruling by the International Association of Athletics Federations that barred double-amputee sprinter Oscar Pistorious
from a shot at the Olympics has been overturned by the Court of Arbitration for Sport. Detractors from Oscar's entry into the Olympics have cited a suspect study that says Oscar could be using as little as 25% of the energy of other sprinters, thanks to the mechanical advantage of his "Cheetah" prosthetics, which basically act as springs. Others feared that this could set a dangerous precedent for the entry of bionics into athletic competition, but the ruling was rather tightly worded, and if related cases come up they will be tried individually. Of course, Oscar still has to qualify, and his personal best in the 400 is about a second off the qualifying time for Beijing. Even if he can't make it, he plans try for the world championships and the London Olympics in 2012.
