Researchers Create Real Tractor Beams

Gadgetank writes "Researchers out of the Australian National University have created a device, working in conjunction with other necessary devices, that can literally move small particles with light. And only light. The way it works is by shining a hollow laser beam around some tiny glass particles. The researchers heat the air around the particles, and therefore cause the dark center of the beam to remain cool."

This story is a reflection caused by bouncing the other story from a mirror using hollow laser beams.

So when a deer in the road moves toward me because I shine my headlights down the road, my headlights are attractor beam?

There, fixed it for you.
