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.


How A Laser Beam Cooks Bacon

Video: When you use a laser to cook bacon, you might not get the same invigorating, impossible to resist smell you do when you fry it but you do score some awesome points for using a freaking laser to cook bacon. Munchies went to Japan to see how laser cooking a bacon strip is done: it requires laser cutting tech and detailed mapping to cook the strip of bacon exactly the way you want it. Program the machine to point the beam where you want and pew pew bacon.


A Laser Has Been Used To Chill Water For The First Time Ever 

Point a laser at someone’s skin and they will react in fear, assuming it’s going to burn. But researchers at the University of Washington have come up with a way to make a laser that cools, instead, successfully lowering the temperature of water by about 2C.
