Optogenetics is a method of using light to control cells in the brain. It can be used to alter behavior, model diseases, and maybe even one day, deliver drugs right where you need them. And now, it's wireless! With lasers!
It's a well-known fact that we here at DVICE will write about more or less anything involving lasers, even if it doesn't involve lasers. Fortunately, this display system actually does involve lasers, and it also involves invisibility. Whoa.
How high-speed can a high-speed camera get? Try fast enough to watch a pulse of light itself move through a soda bottle.
In response to civil unrest in August that threw the U.K. into chaos, police forces there plan to trial a laser weapon that would cast a ten-foot wall of light that briefly blinds those caught in its path at a distance of 1,600 feet.
Attention, citizens! The latest threat to freedom and democracy has been announced by the U.S. Air Force: WEEDS! And they need you to help develop technology to defeat aforesaid weeds by inventing some sort of "floral disruptor." And yes, they do mean "disruptor" like Romulan-style. ZAP!
We've already seen laser systems that can target and shoot down mosquitoes, and we'll be honest: it's hard to beat an anti-bug battle laser. A new technique based on lasers and infrared light might be a slightly more realistic way of keeping mosquitoes at bay without having to zap each and every one.
Have you always wanted blue eyes, but are stuck with boring old brown eyes? Well, a doctor in California has come up with a way to turn someone's brown eyes blue in just 20 seconds.
For NASA, asking boffins to develop one laser-based tractor beam must not be difficult enough, because they've thrown down $100,000 for three entirely different flavors of the technology, which apparently does in fact exist.
Researchers at Sandia National Labs have mixed four different diode lasers to produce a warm, bright white light that they say is just as good as incandescents and better than LEDs. Laser light bulbs, here we come!
To squeeze laser into things like airplanes, we're going to have to make the weapons much smaller and more efficient than the boat-sized platforms we've got right now. DARPA is hard at work on a system called Excalibur that's small enough and powerful enough to make an aircraft like this a reality.
