Researchers Create Real Tractor Beams 111
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."

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.

Ain't the English language a funny thing? Tugboats push instead of tug/pull. People park in driveways. And so on.
Not really, no. Tugboats primarily pull, although they can also push. And a driveway is a path which you drive on in order to reach the house. You could park your car on a driving-range, too, but that wouldn't make the name inappropriate.
