Hasta La Gadget!

Another day, another laser… well, not so fast. This particular laser just so happens to officially carry the “world’s largest title.” Built at Lawrence Livermore National Laboratory in Livermore, California, and housed in the National Ignition Facility — or NIF — it was completed at the end of March, and has just now been officially dedicated and opened for business. The laser inside the three-football field-sized building will aim to create a “star” on earth by focusing 192 beams at a pea-sized target, generating temperatures over 100 million degrees and pressure over 100 billion times the earth’s atmosphere. The process will create nuclear fusion — the reaction that powers the sun and the stars. it sounds pretty complicated, and we’d hate to be in town if something goes awry, but we’re crossing our fingers for the team! Hit the read link for much, much more information about the project.

For the longest while, scientists have been flummoxed by the incessant coruscating emitted by individual molecules; no matter their methods, they could never quite seem to overcome a troubling optical quirk known sensibly as “blinking.” Thanks to a brilliant crew at the University of Rochester, however, we now understand the basic physics behind the phenomenon, and together with a team from Eastman Kodak, a nanocrystal has been created that can constantly emit light. In theory, the discovery could lead to “dramatically less expensive and more versatile lasers, brighter LED lighting, and biological markers that track how a drug interacts with a cell at a level never before possible.” Indeed, one could envision that future displays could be crafted by painting a grid of differently sized nanocrystals onto a flat surface, making even OLED TVs look chubby in comparison. Now, if only we had a good feeling that such a device was destined for a CES in our lifetime…

You may think that the Navy‘s just the baby brother to the two other US Armed Forces, but its weapon development record definitely shows otherwise. Just over two years after building an 8-Megajoule railgun, the branch has penned two $7 million checks to defense contractors Boeing and Raytheon for the design and development of a free-electron laser (FEL). For what it’s worth, such a device has been yearned for since a day after the dawn of time, as unlike chemical-based lasers, the FEL would be 100 percent electric and easier to move. For those unaware,this stormy petrel of a weapon would be used to blast down missiles in mid-flight, all while putting on a pretty impressive light show. ‘Course, the Navy must also figure out how to build a massive energy generating ship in order to use it, but let’s not get too far ahead of ourselves here, okay?

If you thought Mitsubishi’s LaserVue HDTVs were the beginning and the end of laser-tech in boob tubes, think again. Mitsu’s line is carrying on, but the brightness and depth of color offered by that telly are apparently just the beginning of what’s possible according to researchers at the Centre of Molecular Materials for Photonics and Electronics at the University of Cambridge. They indicate that the use of liquid crystals in concert with a single, laser-based light source would result in the same color depth but at a lower cost and higher reliability than the LaserVue, which requires separate lasers for RGB. What cost, exactly? That, dear reader, remains to be seen, but given the source we’re thinking you have plenty of time to save up — and to practice those Dr. Evil impressions.

Ah, the wonders of CanSecWest. The famed security conference has delivered yet again in 2009, this time bringing to light two simple sniffing schemes that could be used to decipher typed text when keyloggers are just too noticeable. Gurus from Inverse Path were on hand to explain the approaches, one of which involved around $80 of off-the-shelf gear. In short, curious individuals could point a laser on the reflective surface of a laptop between 50 feet and 100 feet away, and then by using a “handmade laser microphone device and a photo diode to measure the vibrations, software for analyzing the spectrograms of frequencies from different keystrokes, as well as technology to apply the data to a dictionary,” words could be pretty easily guessed. The second method taps into power grid signals passed along from PS/2 keyboard outputs, and by using a digital oscilloscope and an analog-digital converter, those in the know can pick out tweets from afar. Check the read link for more, and make sure you close those blinds and pick up a USB keyboard, pronto.
