Los Alamos National Labs is often associated with bombs, and the one it dropped today is no less likely to stir up a firestorm. Figuratively speaking, of course.

We need laser beams coming from all directions so there's a force on the atom opposite its motion regardless of which direction it's moving. It's like a bicyclist's nightmare: Whichever way you go, the wind is against you.

It lets you manipulate microscopic particles.
