In 2008, the International Association of Athletics Federations (IAAF) banned double amputee Oscar Pistorius from racing in the 2008 Summer Olympics. Later that same year, the ban was reversed. The back and forth centered on Pistorius' specially designed, spring-loaded, prosthetic legs. The IAAF argued that artificial legs designed especially for running gave Pistorius an unfair advantage against runners whose flesh-and-blood limbs didn't benefit from advanced engineering and space-age materials.

The 2010 snowmobile season, which begins this month, will see daredevils in places they couldn’t reach before: in deeper powder, on remote cliffs, squeezing between trees. That’s because the first full air-suspension sled swaps the usual heavy steel coils for air-filled shock absorbers, creating a smoother, 20-pounds-lighter machine. Riders can easily steer the FX Nytro MTX SE 162 with their weight, glide it nearly drag-free through powder, and unstick it from drifts.

Back when pitching meant Mordecai "Three Finger" Brown gingerly tossing baseballs so worn down that they resembled leather hacky sacks, players didn't need to worry about lifelong injury after getting hit by a pitch. But now that 'roided up monsters can hurl the ball fast enough to cause serious damage, players need something substantial to protect their dome.

Right now the next baseball great may be warming up, not on a Little League diamond, but in a lab. Researchers at the University of Tokyo have pitted a robotic pitcher against a robotic batter to show that the robots can respond to each other at high speeds.

The pitcher is a three-fingered robot arm that was developed by the University's Graduate School of Information Science and Technology: it can open and close its fingers 10 times a second. This allows for precise pitching that lands in the strike zone 90 percent of the time. The batter is an arm developed by MIT that has a 1000-frame-per-second camera eye attached to detect incoming pitches.
