Odorprinting

Odorprinting refers to the ability to identify an individual based on their unique "signature" scent. Research from the Monell Chemical Senses Center in Philadelphia, Pennsylvania confirms that individually identifiable scents in mice do not change regardless of diet. This finding strengthens the possibility that odorprinting may be used to identify and track human beings.The Philadelphia Inquirer: New Way to Sniff Out Criminals (November 10, 2008)
