Gurus develop way to shrink atomic clock... with lasers
The world's most accurate clocks got even more accurate just a few years back, but now a team from the University of Nevada in Reno is looking to make the atomic clock way, way smaller. Housed at the National Institute of Standards and Technology (NIST) in Boulder, Colorado, these so-called "fountain clocks" send out clouds of caesium atoms through a vacuum chamber in a magnetic field; from there, microwaves in the chamber excite the atoms and then emit light as they drop to a lower hyperfine state. All that rocket science aside, the real point here is that all that magic requires a chassis about the size of a modern day refrigerator. Andrei Derevianko and Kyle Beloy have conjured up the idea of "trapping atoms in place using lasers," which would obviously require far less space for the time telling to happen. Just think -- a chicken in every pot and an atomic clock on every wrist.[Image courtesy of PSU]
Scientists shoot down malaria-carrying mosquitoes with frickin' lasers
Seriously, is there anything a laser can't do? A team of mad scientists in Washington have concocted a system that could essentially eliminate malaria-carrying mosquitoes with lasers, and the whole thing can be built from parts sourced on eBay. The so-called mosquito laser is credited to an idea from Lowell Wood, an astrophysicist who worked with Edward Teller, the "architect of the original plan to use lasers to shield America from the rain of Soviet nuclear arms." In theory, at least, the technology could one day be used to draw a laser barrier of sorts around a village. Of course, the trick is to make the lasers powerful enough to smoke the bugs without harming humans -- any of you Earthlings up for a clinical trial or two?[Via eHow]
High-powered, jet-mounted laser one step closer to flying the terrifying skies
The jet-mounted laser anti-missile system, brainchild of Northrop Grumman, Lockheed Martin, Boeing and the US Air Force, has been an ongoing project for quite some time. Well, it's progressed into a final test phase, as evidenced by a new video, which shows the plane strapped with a pilot-controlled laser which is able to intercept missiles significantly earlier than other existing anti-missile tech. The project has plans to continue testing throughout this year, but will also need to be approved by the Obama administration if it is to come to fruition. Feel free to insert obligatory Dr. Evil joke in comments. Check out the video after the break, but fair warning: it autoplays.
First shot fired in war of robots vs humans with lasers, we're winning so far
Boeing just announced a (public) first: they shot a UAV out of the sky using the Laser Avenger (an aptly-titled Humvee-mounted laser), the first time a combat vehicle has used such a weapon to knock a flying robot out of the sky. Naturally, the report is short on details, but they did say that they managed to burn a hole in the enemy, quite the feat for a moving target. Of course, once the robots get lasers, we're all done for.
Light Lane concept would protect cyclists, bring Tron to life
Sadly, there doesn't seem to even be so much as a prototype of this one just yet, but we're certainly hoping that this so-called Light Lane dreamed up by Alex Tee and Evan Gant of Altitude sees the light of day sooner rather than later. The idea, as you can see above, is to project a bike lane wherever the cyclist travels, which would give drivers a clearer indication of where not to tread than a simple safety light or reflector is able to do. The key to the setup is, of course, frickin' lasers, though it seems you'd have to provide your own "zoooommmmm" sounds as you pedal around town.
LaserGames mouse emulator: more fun than blinding a 747 pilot
LaserGames is a mod for projectors allowing up to two players to interact with a game using a run-of-the-mill (red or green) laser pointer in place of a mouse or controller, minus the precision response. Developer Alpay Kasal of Lit Studios isn't giving any hints on how this thing works, but we imagine it uses sensor technology similar to interactive projections -- you know, the ones where a video is projected on the ground and you get to kick around a soccer ball and then watch some tacky Nokia ad at the end. If you're up for trying this out first hand, Kasal's prototype will soon be on public display for some wild and crazy retina burning action -- no word yet on when or where. Check out his video after the break.
Boeing completes successful test of air-to-ground laser turret, enemies are teh doomed
It's about time Boeing went and shot that frickin' laser. The Boeing Advanced Tactical Laser C-130H aircraft has completed its first ground test, shooting a high-energy chemical laser through a beam-control system. The gun successfully acquired a ground target and shot the darn thing on August 7, paving the way for an in-air test later this year, hopefully from that bad-ass 747 they've been touting. Boeing promises that the ATL will "destroy, damage or disable targets with little to no collateral damage." Yay for surgical strikes? Maybe some popcorn?
GM designing car windshield that does the looking for us
Apparently not everyone at General Motors is toiling away in an attempt to get the Volt ready for its 2010 debut, as another sector of the outfit's R&D division is busy creating a windshield that will, at its core, enable us to stop running stuff over. The futuristic glass would utilize lasers, sensors and cameras in order to help drivers see the road's edge better, recognize obstructions and enhance things ahead of us so we'll theoretically react faster. Truth be told, the device is being designed with older drivers in mind, though we don't see why younger motorists won't benefit all the same. Unfortunately, it sounds as if you'll have to keep those toothpicks in your eyelids for a few more years, but at least we're one step closer to full-on autopilot.
Laser headband for Alzheimer's patients, and for really cool people
Look, how many times to we have to explain this? Lasers + headbands = a very good time. We're not sure what you don't get about that, and frankly we're a little disappointed. Alzheimer's patients like laser headbands (laserbands, for short, artist's rendition above) just fine, since the technology is providing a potential way to scan and diagnose brains for Alzheimer's while the patient is still alive -- doctors currently have to rely on symptoms for diagnosis, and a post-mortem look at the actual brain tissue to know for sure after the fact. There are still a few kinks to work out, but this could be a big breakthrough for the detection and treatment of Alzheimer's, and the fashion ramifications are unimpeachable.
Sun aims to speed up data by swapping wires for frickin' laser beams
It's far from the first time we've seen lasers touted as a means of boosting data speeds exponentially, but Sun seems to think it has a better chance than most of making it a reality, thanks in no small part to $44 million in funding from DARPA. As The New York Times reports, that cash haul will be put to use to "explore the high-risk idea of replacing the wires between computer chips with laser beams," which would not only allow for computers to be smaller, but as much as a thousand times faster as well. Needless to say, however, there's quite a few significant hurdles to overcome before that happens, and even Sun itself admits that there's a "50 percent chance of failure." They also say, of course, that the potential benefits are worth the risks, with them even going so far as to boast that the technology would be a way of "breaking Moore's Law."
Researchers devise method for colorizing metals, alchemists swoon
Unfortunately, Dr. Chunlei Guo of the University of Rochester hasn't yet figured out how to turn scrap metals into gold, but he, along with Dr. Anatoliy Y. Vorobyev, has discovered how to colorize a variety of metals. By utilizing a "femtosecond laser processing technique," the duo has crafted a method for turning even aluminum into aluminum with an impeccable gold finish. Furthermore, they've also been successful in turning tungsten dark blue, leaving reason to believe that nearly any metal could be altered to appear as a different color. Ah, just imagine what these folks could do with your MacBook Pro.[Via The New York Times, thanks Jonathan]
Femtosecond laser pulses could safely destroy viruses, bacteria
The world is already well aware of just how potent (and useful) femtosecond lasers are, and a recent study conducted by a team of Arizona State University physicists explains how pulses could be used to dismantle viruses and bacteria without harming a single innocent cell. Rather than follow in the footsteps of indiscriminate laser treatment options, the group of Sun Devils reportedly figured out a way to "produce lethal vibrations in the protein coat of microorganisms," which has the potential to at least treat "blood-borne diseases such as AIDS and Hepatitis." The technique, dubbed ISRS (Impulsive Stimulated Raman Scattering), has shown to not harm healthy human cells while fighting the good fight against viral pathogens, and while there's no easy way to surmise how quickly we'll see this in action, we're gonna wait for a bit more proof before getting our hopes up.[Via Switched]
Japanese scientists make breakthrough in space-based laser power
The Japan Aerospace Exploration Agency (JAXA) and Osaka University have been working together to develop a device which converts sunlight into laser-light with four times the efficiency of previous attempts. According to a report out of Tokyo, the team is working on Space-based solar power systems which can collect sunlight in space and convert it into laser light, which is then transmitted to Earth and used for electricity... or to power a massive Death-Ray. The project works by storing sunlight-based energy in plate made from a sintered powder of metals like chromium and neodymium. When weak laser light is shined onto the plate, the stored energy is transferred to the laser where its strength is amplified by a factor of four. In one test, a 0.5-watt laser was amplified to 180-watts by the plates. Scientists have thus far been able to garner 40-percent of the solar energy produced, and they hope to have a system ready for satellite mounting by the not-too-distant year 2030. Huzzah!

Australian physicists develop teleportation scheme for atoms
Although the idea of teleporting individuals from one place to another in order to sidestep the headache of rush hour traffic has been around for quite some time, a team of Australian physicists are busy making it work (on a smaller scale, of course). Granted, they don't fully expect their teleportation scheme to be used on humans in the near future, but there's always hope, right? Anyway, the team has developed a so-called "simple way to transport atoms," which involves bringing the atoms to almost absolute zero, beaming them with two lasers, and using fiber optics to transport them to any other place at the speed of light where they "enter a second condensate" and reconstruct. We'll keep you posted on when human trialing (hopefully) begins.
Life imitates art: moon to be equipped with frickin' lasers?
Up until now, if you wanted to test some theories about the Moon, its distance, or deviations from general relativity, you would have to shoot a laser from Earth to a group of old, dusty and imprecise reflectors from the Apollo era, which sit on the surface the big cheese -- but that might all be changing. NASA announced recently that it's funding development of a moon-based laser system, which would answer the laser bursts from Earth with its own, thus cutting down on fluctuations in readings and allowing for a more accurate study of the Moon's distance. Because there's no better way to spend several million dollars than sending a laser up to the moon to clarify a few millimeters of uncertainty.
Behold the Laser Dance Matrix (it ain't no "pad")
Frustrated with your flaky roll-up dance pad? Intrigued by things with lasers in them? Alright, we're all in the same boat then. The Laser Dance Matrix (cause it's not really a "pad") was designed to work with any dance game that supports USB input and uses the aforementioned laser technology to register button presses. Breaking the beam = pressing a button. The writeup does not detail how to build one yourself, but they do have a poll asking if there's interest in either purchasing one, either in kit or fully assembled state. Our (imaginary) sources inform us that West Virginia is interested in placing a rather large order.[Via hack a day]
High school students laser-enable the disabled
The students on the Palo Alto High School InvenTeam arrived at the Stanford Cool Products Expo this year with a new system designed to allow quadriplegics to operate all kinds of gadgets and appliances. The user shakes his head to activate a glasses-mounted laser, which he can then point at sensors embedded in an array of custom triggers placed around the home. So far the team's nailed the basic on/off circuit needed for lights, fans, and a pet food dispenser (which is currently shelling out M&M's to Expo attendees), but the real noise is their plan to extend the system by building a small robot that will perform various tasks. According to the school, team captain Guy Davidson was only kidding a little when he said the team hoped "to have [the user] vacuuming in a few weeks." While this isn't the first time we've seen lasers used to assist the disabled, you gotta wonder what's going to happen to their altruisitic spirit when these kids realize they can also just headmount one of those crazy high-powered laser pointers.Read - CNET Cool Products Expo video (second item)Read - Palo Alto High School press release (6MB PDF)
Cheaper blue lasers on the way?
Whether the format war is over or not, one thing that would definitely get more buyers off the fence and owning more high definition players would be lower prices. Aonex Technologies and Kyma Technologies are the latest to announce they've found a better (and cheaper) way to pump out the blue laser diodes necessary in every Blu-ray and HD DVD player. Aonex claims its A-Sapph wafer technology improves on current sapphire based processes, enabling an increase in the number of chips per wafer and improving yields substantially. As fans of lasers in general, and not just in relation to HDTVs and lower prices, we're excited, but without even the hint of an expected release date it will probably be a while before these are ready for the market.
Raytheon and Northrop Grumman making progress on frickin' lasers
Face it, living out your childhood Spaceman Spiff-esque fantasies with Nerf guns just isn't cutting it anymore; what you need is a laser gun, and on the double. Lucky for you, Raytheon and Northrop Grumman are honing in on weapons-grade laser designs of their own, with Raytheon claiming recent tests were successful detonating 60mm mortars, while Northrop Grumman is gearing up a new "directed energy production facility" for cranking out high-power laz0rs -- and we're sure they'll let you borrow a few if you just ask politely. Right now, weapons-grade is defined as 100kw, a mark neither manufacturer has reached yet, and there's a slight lack of clarity as to exactly how fancy Raytheon's current system is, since it esploded a non-moving target at 550 yards, which is possible for lots of lasers given enough time. Northrop Grumman is a bit more forthcoming with the facts, like crystal shrinkage to the tune of 50%, which should help make these things small and rugged enough for field use, but they won't be ready to demonstrate 100kw in action until the end of next year.
