You might not see leaves as hazards, but train operators would beg to differ -- foliage on the tracks not only makes it harder for trains to stop, but also messes with anti-collision signals. The greenery might not be much of a danger for much longer, however. Dutch Railways is testing a laser sys

At first glance, the satellite image above may seem like one of the many that have been shared in the past. What you're looking at, though, was delivered in a much more timely manner than the imagery which came before it. For the first time ever, the European Space Agency has used a laser to beam

Your smartwatch may may be the height of wearables today, but it can't get you out of a supervillain's elaborate death trap. That's where Patrick Priebe's LaserWatch comes in, which is like something out of a Bond flick. On the surface, it looks like any other digital watch. But hit a button and y

Twisted laser beams have been used to send up to 2.5 terabits per second of data over fiber-optic cables, but the technique has never been worked very well over the air. Researchers in Vienna managed to use those bizarro quantum laser properties, also known as orbital angular momentum (OAM), to be

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

An art installation from the Koln International School of Design aims to give us a feel for the ethereal radio waves we take for granted every day. Binairy Talk, created by Niklas Isselburg and Jakob Killian, uses a sound generator and pulsing device to fire smoke rings at a laser sensor. Those ar

What with their simple genetics and ultra-brief lifespan, poor fruit flies are the go-to insect for mad scientists. Researchers have discovered a new way to make their lives miserable with a mind-altering project called FlyMAD (not kidding). There's even an overly-elaborate plan: motion tracking c

We imagine that on May 16th, 1960, when the first laser was fired, no-one involved was particularly concerned with the invention's impact upon pop culture. After all, proving Albert Einstein's 1917 theory about amplifying light by the stimulated emission of radiation was probably seen as a bigger

While we're monkeying with our MakerBots, large corporations have much better toys to play with. They insist on calling them \"additive manufacturing\" machines but, truth be told, they're just Replicators with a superiority complex. They sinter or melt powdered or solid metals using lasers or elect

If there's one thing you should know about Engadget, it's that we absolutely love lasers. And thanks to the University of Arizona and University of Central Florida, our favorite pulsating form of light might soon find a much less destructive purpose, than say on Navy ships, anti-missile airliners

Many X-Men fans want to be Wolverine, but the cool kids know that Cyclops is the real star. How can you beat lasers for eyes? Patrick Priebe is most certainly aware, as he built a real-world set of laser-blasting goggles to emulate Cyclops' optic blasts. While the wearable isn't powerful enough

Lasers are indisputably awesome, and NASA just made them a little more so by zapping a record-breaking 622 Mb of data per second between the moon and earth as a part of its Lunar Laser Communications Demonstration (LLCD). Pulsed laser beams were shot from ground control at the White Sands Test Fac
