Ray guns are high on the list of "physics gone wrong" movie tropes. Unlike the real thing, the blasts are much slower than light, visible in clear air and (depending on who's firing) highly inaccurate. However, laser physicists in Poland have just shown what a powerful laser really looks like. Tho...

Intrepid 6-wheeler Curiosity perhaps protested too much when it tweeted "Yes, I've got a laser beam attached to my head. I'm not ill tempered; I zapped a rock for science." NASA turned the rover's high-powered laser loose with 30 pulses of a million watts each, reducing a thin layer of the chosen ...

Wanna create your very own microscopic steam engine? Just take a colloid particle, put it in water, and add a laser. That's a CliffsNotes version of what a group of German researchers recently did to create the world's smallest steam engine. To pull it off, engineers from the University of Stut...

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...

Researchers at Japan's Kyoto University have recently announced a breakthrough method for shaping laser beams that could result in optical disc capacities up to ten times higher than what's current available from state-of-the-art HD DVD and Blu-ray discs. Using several layers of so-called photonic c...

In a proposal that would surely bring a tear to the late Ronald Reagan's eye, Air Force officials are attempting to co-opt $5.7 million from the 2007 budget for developing high-energy lasers that could be used to destroy enemy satellites (because, you know, al Qaeda is launching birds left and right...
