The Department of Homeland Security will soon be using a laser at airports that can detect everything about you from over 160 feet away. It can actually read you on a molecular level (in case you’re hiding something in your genes?)

It will be able to read your adrenaline levels (measuring your level of tension and excitement), as well as find traces of drugs and gun powder your clothes, all without a physical search.

The scanner is called the Picosecond Programmable Laser (PPL), and works by blasting its target with lasers which vibrate molecules that are then read by the machine.

How can we find home-grown terrorists who have been indoctrinated by (usually) internet propaganda, like Army psychiatrist Nidal Malik Hasan, who opened fire at Fort Hood, Texas, in 2009, killing 12 people and wounding 31 others?

The Defense Dept. intelligence Agency (DARPA) is asking scientists to look at the emails of groups of people around the world and create a program that can "make them quantitatively analyzable in a rigorous, transparent and repeatable fashion." Armed with this program, the military can target groups that are vulnerable to terrorists’ recruiting tactics, and perhaps even counter their messages with emails that give the opposite views.
