Anyone with a colour printer knows that selling replacement ink cartridges is the quickest way to become a millionaire. But what if your printer never needed a single drop of ink to produce colour images at impossibly high resolutions? A new laser printer can already do that by etching microscopic patterns onto sheets of plastic.

Some SETI researchers believe the best way to detect aliens is to search the skies for their laser beams. In the largest survey of its kind, astronomers scanned 5600 stars in search of these optical signals — and they found... absolutely nothing. Nada. Zilch. Here's what that means to SETI and the ongoing hunt for alien intelligence.
US military bigwigs gathered in Orlando this week for the annual AirWarfare Symposium to discuss big plans for big weapons that do big damage. According to a report, the biggest unfunded project that US Special Operations Command hopes to push through is a C-130 that's equipped with a power laser weapon.
Video: This immersive laser beam installation seems like the perfect place to stare at some lights, cleanse yourself from sin and, like, maybe even just leave your soul behind. The room is so huge and the lasers come from everywhere that it must be a hell of an experience. Like, you're trapped inside a machine. Or the future. Or another dimension entirely.
Wicked Lasers is known for its handheld lasers and torches that redefine what it means to be bright. A few years ago it released a torch that was intense enough to start a fire, and now the company has managed to dramatically shrink its design so you can easily bring it the next time you go camping and leave the matches at home.
A new generation of tabletop accelerators has the potential to accelerate electrons to near the speed of light, without the need for gigantic machines like the Large Hadron Collider. But that all-important energy beam is too spread out for optimal performance. An international team of physicists has figured out a way to address this shortcoming and described their method in a new paper in Physics of Plasmas.
Humans have long dreamed of discovering intelligent life beyond Earth. But truth is, we have no way of knowing if an alien civilisation would be friendly or hostile. Should we have the rotten luck of discovering the Borg, we'll need to get our collective asses into hiding quickly — and a team of astronomers thinks they know how we can. Naturally, it involves lasers.
When war changes, it usually changes slowly. We’re used to military technology advancing in predictable, plodding steps – incremental advances on what went before, with one side spending years developing its new plane, or tank, or missile, the other side simultaneously developing ways to undermine it. The first nation builds a thing, the second builds a thing to make it irrelevant, and so the gears of the military-industrial complex keep on a-grinding.
Video: The weather has been really fun and generous with lightning strikes these days. We've seen it destroy trees and gotten an up close view of it striking but this one might be the coolest angle yet: from outside a flying aeroplane window. The lightning hits the tip of the wing and then streaks in a straight line like a laser shooting out. Pretty cool.
A certain medical dye will stick together when hit by a laser, effectively suturing a wound without the need for staples or traditional sutures. But the dye will only penetrate as deep as the light does, so this method only works on superficial wounds. The solution is a biological wave guide to direct the light deeper into the wound.
