Hasta La Gadget!

It’s a nightmare of epic proportions: the finger prick. Anyone who detests ’em completely understands, and they’ll also be supremely appreciative of the work being done by Dr. Karan Kaler and co. at the University of Calgary. Kaler’s team has created a new lab-on-a-chip technology, which uses a wireless microchip to analyze nanolitre-sized samples of blood. That’s far less fluid than is currently needed to run a gauntlet of tests, and this fresh take is also far more efficient. We’re told that it “involves creating a structure called a micro-emulsion, which is a droplet of fluid captured inside a layer of another substance.” From there, the emulsions are positioned precisely on the chip, and after tests are ran, the results are piped wirelessly to a computer. The potential here is far more impressive than the existing iteration; the long-term vision is to “create handheld devices for patients to use at home for testing fluids, such as blood and urine,” which would prevent extensive wait times and enable patients to get vital information faster. There’s no telling how long it’ll take to escape the lab and land in the hands of those who need it, but we’re sure the folks involved are cranking just as hard as they can.

We know you are vigilant enough not to trust your car’s security to a wireless system, but plenty of other folks like the convenience of putting away the metallic keys and getting into their vehicles with a bit of Bond-like swagger. Professor Srdjan Capkun of ETH Zurich found himself perched on the fence between these two groups when he recently purchased a vehicle with a keyless entry system, so he did what any good researcher would: he tried to bypass its security measures. In total, he and his team tested 10 models from eight car makers and their results were pretty conclusive: each of the tested vehicles was broken into and driven away using a very simple and elegant method. Keyless entry systems typically work by sending a low-powered signal from the car to your key fob, with the two working only when they’re near each other, but the wily Zurich profs were able to intercept and extend that signal via antennas acting as repeaters, resulting in your key activating your car even when it’s nowhere near it. The signal-repeating antennae have to be pretty close to both the key and the car, but that’s why heist movies stress the importance of teamwork. Hit the source link for all the chilling details.

Research shocker! Keyless car entry systems can be hacked easily, elegantly originally appeared on Engadget on Sun, 16 Jan 2011 19:07:00 EDT. Please see our terms for use of feeds.

You know, we could just leave you with the image above and be done here, but its backstory is almost as cool. Researchers at the Florida Institute of Technology have built a 1,500-pound X-ray camera that can shoot ten million frames a second and then pointed it at a nearby flash of lightning to try and learn more about it. How did they know where the lightning would strike? Well, in true scientific fashion, they caused it themselves! This was done by shooting rockets into thunderstorms, with attached wires directing the flow of energy down into their target zone. The imagery produced from the X-ray sensor is actually extremely low-res — a 30-pixel hexagonal grid is all you get — but it’s enough to show that X-ray radiation is concentrated at the tip of the lightning bolt. What good that knowledge will do for the world, we don’t know, but we’re sure it’ll provide nice fodder for the next round of superhero empowerment stories.

Ah, those zany Keio University researchers trying to recreate Smell-O-Vision, do you want to know what they’re up to these days? They’re still trying, of course, but now they’ve taken the opportunity to demonstrate their hardware — which uses basic inkjet printer tech to fire off very short bursts of fragrance — to tech lovers in Japan while still tweaking and refining it. Primarily aimed at helping healthcare professionals in assessing a patient’s sense of smell, the Fragrance Jet II has a high degree of control granularity, permitting the varying of both intensity and duration of a scent, which in turn can provide a very accurate measurement of a given person’s olfactory acuity. A mobile prototype has also been trotted out (pictured above), hinting at the possibility of eventually shrinking these modules to fit inside cellphones and thus leading us to an awesome future of customizable “incoming call fragrances.” Awesome indeed. Video after the break.

Not to denigrate the numerous fine hacks that Kinect‘s undergone since its launch, but it’s always nice to see the professionals come in and shake things up a little. A crew from MIT‘s brain labs has put together a hand detection system on Microsoft’s ultra-versatile cam, which is sophisticated enough to recognize the position of both your palms and fingers. Just as a demonstration, they’ve tied that good stuff up to a little picture-scrolling UI, and you won’t be surprised to hear that it’s the closest thing to Minority Report‘s interactive gesture-based interface that we’ve seen yet. And it’s all achieved with a freaking console peripheral. Video after the break.
