Researchers develop tiny tractor beam, and they’re sure they could make a larger one

Wow! So this is really cool!

From RawStory.com: Researchers have developed a small-scale laser beam capable of moving microscopic particles nearly 8 inches, an important step in developing a “tractor beam.”

Previous attempts have used the motion of protons to transfer tiny particles, but a team at The Australian National University used heat to move 0.2-mm particles up to 7.87 inches – which is about 100 times farther than had been done previously, reported CNET.
