New 3D Printer Draws In Midair Like Magic

Lasers and metal were part of 3D printing for decades before the machines became affordable for personal use. But researchers at Harvard are demonstrating a new technique by which 3D metal structures can be printed in midair, without the need for anything supporting them.


We're One Step Closer To Better Tabletop Particle Accelerators 

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.


This Is How We Could Hide Our Planet From Bloodthirsty Aliens

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.


How Lasers Will Change The Way We Fight Wars

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.


Lightning Hitting An Aeroplane Wing Looks Like Lasers Shooting Out From It

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.


Someday, Suturing A Wound Will Involve Lasers 

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.


This Is What You See When You Scan A Forest With Lasers

Do not adjust your monitor. This is a perfectly normal forest, but it happens to be the view that’s seen through the eyes of a 3D laser scanning system developed by a company called Treemetrics.


What Is The Most Powerful Weapon In Sci-Fi History?

Image Cache: What’s the most powerful weapon in the sci-fi universe? How does a lightsaber in Star Wars compare to the energy sword of Halo? What about a Death Star vs Doctor Who‘s reality bomb? And how do they match up with a real life nuclear bomb?


Turn Your iPhone Into A Laser Measure With This Tiny Headphone Jack Accessory

iPin was the first company to use the iPhone’s headphone jack as an accessory port for a compact laser pointer. And not to diminish the fun you can have with a laser, but the company’s latest product is considerably more useful since it turns your smartphone into a full-on laser measure.


Every Death Star Replica Should Have A Working Metal-Melting Superlaser

There’s probably a good reason — involving lawsuits and lawyers — why toymakers don’t include working superlasers on their Death Star playsets. But since Patrick Priebe doesn’t plan on selling his Death Star replica to the public, he had no qualms about including a terrifying 84-watt laser.
