Lie Detector That Uses Body Odor?
The U.S. Department of Homeland Security says they are studying the possibility of using body odor to tell when someone is lying. Gives new meaning to the term "you stinking liar" doesn’t it?
The department's Science and Technology Directorate said it would conduct an "outsourced, proof-of-principle study to determine if human odor signatures can serve as an indicator of deception. … As a secondary goal, this study will examine … human odor samples for evidence to support the theory that an individual can be identified by that individual's odor signature."
