In electronics heat is often the enemy, but research at North Carolina State University may have resulted in a way to keep things cool in a less-expensive manner than is currently possible. Dr. Jag Kasichainula achieved the feat by using graphene. Compromised of honeycombed carbon atoms, graphene is being utilized for a number of different breakthroughs and experiments; in this case it is combined with copper to create a composite heat spreader. The spreader then connects to the electronic device in question with a indium-graphene film. The higher thermal conductivity of both materials allows the composite spreader to draw heat away approximately 25 percent faster than commonly-used copper versions. Copper is also notoriously expensive,…

For too long Nielsen ratings have dealt with TV commercials and web ads as completely separate entities. Episodes of your favorite show streamed through a service like Hulu or from the channel’s website often didn’t get factored into the pricing and sales of television ads, and vice versa. That is about to change, however, as the media monitoring company has joined forces with GroupM to create Nielsen Cross-Platform Campaign Ratings. The new product will combine its Nielsen Online Campaign Ratings, which measures internet advertising, with its traditional TV monitoring service to create a medium-agnostic tool for creating media metrics. Hopefully, with a unified pool of data and better monitoring services, content producers may be more likely to experiment with online distribution — especially if they influence the flagship ratings. Check out the complete PR after the break.
In our Lytro review, we mentioned seeing a preview of an upcoming mode that allows you to manipulate the perspective of a photo after the fact, using 3D data captured by the camera’s unique sensor. While the Lytro won’t be widely available for a while, you may already have technology with the potential for similar functionality under your TV stand in the shape of Microsoft’s Kinect. James George and Alexander Porter have exploited this in a series of CCTV-inspired images, using custom software to combine the Kinect sensor’s depth information with images from a Canon 5D. The results are striking — George and Porter took candid photographs of passengers on the New York City subway, once intended to have a high-tech surveillance system of…

Jealous of your Nexus S-owning friends and their fancy NFC chips after yesterday’s Google Wallet announcement? Well tech tinkerer Joe Desbonnet has whipped up what he dubs “poor man’s NFC” using an Arduino, some magnet wire, and any compass-equipped Android smartphone (which is almost all of them). By placing a coil of wire on the phone and connecting it to the DIYer’s favorite microcontroller, Desbonnet was able to send data, albeit very slowly, to his HTC Desire running a special app to decode the signals. Granted, you’re probably not going to see American Eagle mod their point of sale systems to talk to your phone’s magnetometer, but it’s still a neat trick. In fact, we’d break out our Arduino right now to give it a try, but our secret lair is strangely devoid of enameled copper wire. Check out the source link for instructions, and don’t miss the video after the break.

There’s those who want electric bikes that’ll hurtle you down the road at 40mph at the twist of the throttle, and there’s those who believe pedaling to be enjoyable enough, but would like a less strenuous bicycling experience. If you find yourself a member of column B, listen up, because Gates, NuVinci, and Bosch have created an e-bike concept that’ll satisfy your two-wheeled transportation needs. Gates supplied its Carbon electric belt drive, NuVinci brought its N360 infinitely variable planetary hub, and Bosch threw in a battery and control system to make a bicycle beauty. The power train is set up to give riders pedal-assist with four settings that go from Lance to lazy, depending on your mood. At an estimated cost of €2,600 – €3,200 ($ 3,680 – $ 4,530), you’ll need a bank account comparable to the seven-time champion of Le Tour should an OEM pick up the design.

Silicon nanoscoops to combine Li-ion’s energy with supercapacitor power, make your electric car go vroom
Look, we don’t know much about “science.” We know it’s a controversial subject, and we always try to steer clear of that sort of hot-button-issue stuff. Still, “science” can do some good in the world, you know, now and then. Some “scientists” at the Rensselaer Polytechnic Institute have happened upon a “strain-graded carbon-aluminum-silicon nan oscoop anode” (whatever that means) that basically combines the advantages of long-lasting Lithium-ion with a supercapacitor’s rapid fire oomph — a common theme, but undoubtedly a noble one. Specifically, Li-ion’s superb (and ever-improving) Wh/kg and supercapacitor’s great W/kg. Now, don’t ask us how — again, “science” — but the upshot should be faster charging and better performing electric cars, that can still manage a good amount of mileage. Hopefully we get more spectacular exploding laptops as a side bonus.

It looks like somebody actually coughed up the extra dollar for the De Luxe model X-Ray specs in the back of Mad Magazine, then reverse-engineered ‘em in the name of science. That somebody is Richard Averitt, whose team at Boston University has come up with a way to use metamaterials and terahertz transmissions to see through you. We’ve seen metamaterials plenty of times before, typically being used for nefarious deeds on the opposite end of the spectrum: invisibility cloaks. Here they form pixels for a digital imager that can be activated by THz radiation. If you’re not familiar with THz radiation, it’s a (supposedly perfectly safe) form of energy waves that pass through materials — much like X-Rays but without all the nasty DNA-shattering effects on the way through. There’s just one problem: nobody (not even this guy) has made a powerful enough THz emitter just yet, meaning we’re all safely naked under our clothes for at least another few years.
