Diminutive cable holds promise in medical, solar realms
We tend to prefer our electronics to be as far from invasive as possible, and that definitely includes cabling. While we'd take wireless over the corded approach any day, tethered applications still have their place, and a diminutive new cable is showing bigtime promise in a few prominent fields. A research team has developed a cable that resembles that of an old fashioned coaxial strand, yet it's reportedly "much thinner than a human hair" and can transmit visible light. By constructing a cable about 300-nanometers wide which houses an inner wire of carbon surrounded by an insulator and an outer wire of aluminum, visible light can pass through, paving the way for its use in highly efficient solar energy cells, or furthermore, "miniature electrical circuitry and microscopic light-based switching devices for optical computing." Researchers even suggest that it could be used in retinal implants or "detecting single molecules of pathogens in the body." We're not yet sure just how potent or powerful these itty bitty cables can be, but judging by size alone, we're halfway sold already.
Inventor crafts GPS-equipped shoes, includes a panic button
We've seen some fairly interesting means of keeping track of your mischievous kids (or pets), but Sayo Isaac Daniel's latest invention takes top honors as the ultimate paranoid parent's must-have gizmo. Aside from the obvious tracking uses, Daniel's GPS footwear is actually intended to beam out a distress signal to a pre-selected recipient if the wearer hits a certain panic button. The GPS-equipped kicks would present the location of the violated victim to whoever is deemed that person's hero, and would hopefully give the rescuer enough time to arrive and lay down the law. Also, the patent explains an "alarm toe switch" that would be inserted within the shoe in order to give customers the ability to sound their alarm (intentionally or otherwise) without making any sudden movements. Reportedly, a company dubbed Quantum Satellite Technology plans to start selling the shoes "in March for around $350 per pair," but the GPS signal emanating from your soles won't do you much good if your kidnapper ditches your footwear before tossing you in the trunk.[Via The Raw Feed]
Chemists craft molecular keypad lock
While the folks behind the AACS could probably use a few pointers about constructing a sufficient lock of their own, a group of scientists at the Weizmann Institute of Science in Rehovat, Israel have crafted a molecule-sized "keypad lock" that "only activates when exposed to the correct password, a sequence of chemicals and light." Organic chemist Abraham Shanzer and his colleagues suggest that their invention could "lead to a new level of safeguards for secret information," but we tend think the infamous hackers of the world would inevitably crack the code. Nevertheless, the molecule -- dubbed FLIP -- houses a core linker that mimics a bacterial compound that binds to iron, and attached to it are two molecules that respectively can glow either blue or green. Using three "buttons," which just so happen to be an acidic molecule, an alkaline compound, and ultraviolet light, the lock can be "opened" if given the right sequence of chemicals and light, and there's a grand total of two noticeable results possible. Interestingly, the researchers have insinuated that their creation could be used to recognize "when certain sequences of chemicals (like harmful toxins) are released in the body," but we haven't heard a 10-4 from the US Army just yet.[Via Yahoo, thanks, Antonio H.]
USB AirSoft turret mows down unsuspecting office mates
Where else but the good ole US of A would we revel in crafting items that not only utilized that oh-so-lonely USB port on the rear of your leased laptop, but had the potential to "deliver welts" to unsuspecting co-workers? While the pre-packaged USB missile launchers are quite the novel desk adornment, this DIY job seriously brings the heat (and the pain). While the modder responsible here envisions a more robust, costly, and dangerous version in the future, his 1.0 edition features a $19 electronic AirSoft gun, the turret base from an aforementioned USB missile launcher, super glue, and the usual compliment of assembly tools. After disassembling the launcher and tapping into its base, a bit of fancy wire work is required to affix the more powerful AirSoft gun to the rotating turret. A few more screws and finagling, and you're all set to demolish the fun at your annual holiday bash, all for just around $70 and a few hours of your time. So if you couldn't handle boot camp, but still have a passion for mechanical sentries, be sure to hit the read link for the full skinny.[Via HackADay]
Dual-screen cellphone prototype: two great tastes that taste great together
Dual-screen cellphones are nothing new, after all, flips have long offered anemic external displays for caller ID and the like with a bigger, higher resolution screen on the inside for taking care of business. Still, two folding screens emerging as one bigazz display a la the 701 ThinkPad's butterfly keyboard would be a welcome addition, right? Seok Hong Jeong thinks so and is presenting his "dual LCD mobile phone" prototype at the Seoul International Invention Fair 2006 in Korea. He's already applied for patents in "overseas markets" which we presume means the USPTO among other freewheelin' entities. Godspeed sir, and please get Sammy on the horn for a couple of those 0.82-mm slim LCD's they like to brag about -- let's keep the bulk down, eh?
