We've all seen how good the Navy's experimental laser is at shooting down drones, but it turns out that the hardware's got more than one party trick. A report by the Wall Street Journal has revealed that military types are also praising the surveillance capabilities of the gear, describing it as a

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

For most of us, high-speed image capture, say 120 or 240 frames per second, is enough to get a good look at stuff happening in the blink of an eye -- like a water droplet hitting the ground or a Bichon Frisé snagging his favorite ball. For faster subjects, industrial-strength high-speed cam

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

It's official: the US Navy has entered the future. Vice Admiral John Miller tells Bloomberg that the USS Ponce, an amphibious transport, has been using the Navy's Laser Weapon System (LaWS) in the Persian Gulf since late August. The high-tech arsenal is no threat to larger vessels, but it's potent

In order to defend itself against small drones, China built a laser-based system that can shoot down the compact aircraft up to 1.2 miles away. According to the official Xinhua news agency, the tech can bring down the rogue flying machines within five seconds of locating them at altitudes of up to

Tractor beams now have a better shot at crossing from science fiction trope to reality, thanks to scientists at The Australian National University (ANU). They managed to push and pull a 0.2mm sized particle nearly 20cm using a \"hollow\" laser beam. That's a hundred-fold improvement over recent effo

Forget the \"walk-and-turn\" field sobriety test; researchers have developed a laser that can detect drunk drivers remotely. A team at Warsaw's Military University of Technology shined a laser beam through a moving vehicle, along with a reflective mirror that bounced back to a detector, to pick up a

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

An unresponsive trackpad can ruin a laptop. But how do you test for that without having access to ready-made equipment? If you're Google, you build your own machine. The company's Chrome OS team has created the Quickstep, a USB add-on that uses a laser to gauge trackpad latency on Chromebooks. Whe

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

Researchers have long sought to generate significant energy from laser-based nuclear fusion, and it appears that they're finally making some headway. Lawrence Livermore National Laboratory reports that laser blasts in September and November produced more energy from hydrogen fusion reactions than
