Tractor beams now have a better shot at crossing from science fiction trope to reality, thanks to scientists at The Australian National University (ANU). They managed to push and pull a 0.2mm sized particle nearly 20cm using a "hollow" laser beam. That's a hundred-fold improvement over recent effo...

It can be difficult to get waterborne objects to go in the right direction -- just ask any boat captain who has had to fight waves on a choppy sea. However, researchers at the Australian National University have developed a "tractor beam" (really, a wave generator) that would make it trivial for y...

We recently saw research that suggested negative radiation pressure in light could lead to a practical tractor beam. A partnership between the Czech Republic's Institute of Scientific Instruments and Scotland's University of St. Andrews can show that it's more than just theory: the two have succes...

Fully functional LightSabre aside, a tractor beam has to be high on most geek wish-lists; lucky for you NASA has started working on one. Before you drop your sandwich (or whatever that object in your left hand is), this won't be for sucking up star cruisers, but the more modest task of sample and...

Lasers. Is there anything they can't do? The latest addition to the 50-year-old technology's bag of tricks comes courtesy of a team of researchers from the Australian National University, who've managed to create a laser beam that effectively functions as a tiny tractor beam. The key, it seems, is t...
