New Detectors Sniff Terrorists’ Scents

`The Pentagon’s fringe science arm wants to keep track of potential enemies-of-the-state in every way imaginable: not just by sight, or by sound, or by their e-mail; but by their smell, as well.

Darpa’s “Unique Signature Detection Project (formerly known as the Odortype Detection program)” aims to sniff out genetic markers in “human emanations (urine, sweat, etc.)” that “can be used to identify and distinguish specific high-level-of-interest individuals within groups of enemy troops.”

“Recent experimental results” show that chemical compounds in a mouse’s “urinary” scent produces an “odortype” that’s unique to each individual rodent, Darpa observes in its original solicitation for the project. “Although experimental data for humans is far less quantitative,” the agency is hoping that a similarly “genetically determined,” “exploitable chemosignal” can be found in people, too.’
