 Police sources tell ABC News a person of interest has been taken into custody for the attempted rape of a woman sunbathing in New York's Central Park last month. The victim fought off the man, the man off rather. Scientists say they're making huge progress in how prosthetic limbs can interact with the brain. When you see someone walking with an artificial limb, they don't have full neural control over it. Instead, they're likely using a robotic controller to move the prosthesis at a gait that's been pre-programmed into it.
