He estimated that 1% of the population is psychopathic but that the threat of prison and prosecution deters most of them from committing crimes. He differentiated them from sociopaths, who arrive at a similar mentality from cultural rather biological influences. ... More »Host: George Noory

Professor of Cybernetics, Kevin Warwick discussed his experiments in becoming a "cyborg," as well as the inherent dangers in the rise of intelligent machines. In his 2002 surgery, he had an implant "fired into his nerve fiber," which remained there for three months while various tests were conducted, he said. Through wires coming out of his arm he was linked to a pad which relayed information to a computer and the Internet. He noted that he was able to successfully control the movements of a wheelchair just using his thoughts, which showed this technology holds great promise for paralyzed people. In another other experiment, brain signals sent through the Internet from Columbia Univ. were able to move a mechanical hand in the U.K., he detailed. Warwick also described wearing an ultrasonic sensor in which he was able to detect when something moved closed to him, even though he couldn't see it. He views humans moving towards becoming cyborgs as a necessary evolutionary step, as e ... More »Host: George Noory
Historian Glenn Kimball, fresh from a trip to Egypt, discussed his research there investigating several tombs and sites.
