Tractor beams come to life

Have you ever lazily wished you could just use a tractor beam to grab that out-of-reach object? Apparently, you can. Using only light, Australian researchers say they are able to move small particles almost five feet through the air. It's more than 100 times the distance achieved by existing optical "tweezers," the researchers say. Not quite a simple grabby tractor beam, the new system works by shining a hollow laser beam at an object and taking advantage of air-temperature differences to move it around.
