A Collar Laser Pointer Is the Dangling Carrot Your Pet Will Never Catch

The only thing better than a toy that keeps your cat and dog occupied for hours is one that requires no intervention on your part. A ball needs to be tossed, a pull toy needs to be tugged, but this laser pointer that clips onto a collar will have your pet chasing, but never catching, that small red dot until they're… » 10/02/14 5:00pm 10/02/14 5:00pm

Radio Tornadoes Could Deliver Neverending Wi-Fi Capacity Some Day

Coaxial wiring—like what runs into your cable box—revolutionized data transmission by drastically widening the wire's data pipeline. Two years ago, a research team from University of Southern California accomplished the feat using a vortex of lasers. Now, that same team is back with a means of coiling radio waves… » 9/18/14 4:45pm 9/18/14 4:45pm

This Dazzling Laser Show Is Way More Effective Than Any Warning Shot

Warning shots are a waste of ammunition and not a particularly effective deterrent. Instead, modern warfighters inform potentially lost civilians/potential suicide bombers that they're in the soldier's rifle sights by blasting them with laser light from barrel-mounted laser dazzlers like these. » 9/02/14 11:40am 9/02/14 11:40am

Physicists Use Lasers to Chill the World's Coldest Molecules

If you thought last winter was cold, you should stay as far away from magneto-optical trapping as possible. Yale physicists recently used this technique to cool a molecule of strontium monoflouride down to 2.5 thousandths of a degree above absolute zero. That makes them the world's coldest molecules. » 8/25/14 10:54am 8/25/14 10:54am

Time lapse of an airport makes airplanes look like shooting stars

Aside from going through security and lugging around your carry on and rushing to the gate and avoiding human swarms, airplanes are magical places. Okay, maybe not. But there's beauty in how they operate. Just watch this ballet of airplanes at Shanghai's airport. It's like seeing man made shooting stars. » 8/14/14 9:35pm 8/14/14 9:35pm

Making Faster Optical "Cables" Using Nothing But Lasers and Air

Pulses of light are the absolute fastest way to transfer data (because nothing's faster than light), but old school fiber optic cables can only go so many places. Scientists have a new idea: use high-powered lasers to make a column of low-density air that can carry a light signal just as well as a normal cable. Yes,… » 7/22/14 11:23am 7/22/14 11:23am

Scientists Use World's Largest Laser To Recreate Jupiter's Core

It is not pleasant inside the core of Jupiter—or any other planet for that matter. However, gaining a better understanding of what's going on in there is key for understanding how these planets form. That's why a team of scientists at Lawrence Livermore National Laboratory recently used diamonds and lasers to recreate » 7/18/14 11:21am 7/18/14 11:21am

The Navy Wants to Mount an Anti-UAV Laser on a Hummer--A Hummer!

The Office of Naval Research has just announced another breakthrough in its efforts to bring laser-based weapons to future battlefields. What once could only be accommodated by a tractor trailer now fits neatly in the back seat of a Humvee. It's only a matter of time until our armed forces march off to war with GI… » 6/17/14 2:20pm 6/17/14 2:20pm

These Revolutionary Optics Could Make Battlefield Lasers a Reality

Weapons that shoot light rather than bullets are quickly becoming a reality, however their huge bulk and even larger energy consumption still demand that they be mounted on vehicles such as battleships and tractor trailers. But thanks to this newly developed optics system from the US Army Research Lab, tomorrow's… » 6/16/14 4:20pm 6/16/14 4:20pm

NASA's Using Space Laser to Download Video From Orbit at Gigabit Speeds

NASA's latest data download just covered way more distance, and contained way more awesome, than any earthbound file transfer: the agency beamed a high-def video down from the International Space Station this week using a high-powered laser. Go ahead and give your WiFi router a good stern look. » 6/07/14 10:00am 6/07/14 10:00am

Scientists Invent a Laser That Fires Electrical Charge, Not Light

Researchers at the University of Michigan have just stumbled upon the most important development in laser research since the invention of the semiconductor diode in the 1950s. It promises to create a new class of lasers that use 250 times less energy than today's, and that's not even the craziest part. » 6/06/14 11:40am 6/06/14 11:40am

Hobby Drones As Guided Bombs And The Rise Of Laser Defense Systems

"Drones" are changing the world's view of aviation rapidly. At first, larger models such as the Predator and Global Hawk took center-stage in the public's consciousness, but now small unmanned aircraft, some the size of lunchbox or even smaller, are capturing the public's imagination and keeping defense and homeland… » 5/01/14 3:41pm 5/01/14 3:41pm
