Physicists Invent (Tiny) Working Tractor Beam, World Becomes Instantly More Awesome

Geekosystem:

We have tractor beams now! Like where you zap a thing with a laser and pull it toward you with beam power? Yeah, those! We have those now. Even though they are super tiny and effective only on microscopic items like silica spheres suspended in water for right now, they are still working tractor beams, and now that we have the principle down, they are pretty much only going to get cooler from here.
