Hasta La Gadget!

Well, this might be a good reason for The Powers That Be to know your exact whereabouts. According to a team of MIT researchers, speeding up data rates on mobile devices could be as easy as tapping the various motion sensors found in run-of-the-mill smartphones. The scientists believe our wireless infrastructure is at the root of bottlenecks, with a handful of weak transmitters clumsily “handing off” data to one another as you move out of range. The solution: use GPS radios, accelerometers, and even gyroscopes to infer where you’re headed, and then choose an access point near where you’re likely to end up. The difference, they report, is dramatic: a 50 percent boost in throughput, along with improved success in choosing the best bit rate. To boot, if a base station is armed with location-based info, it can better predict when the devices connected to it are on the verge of losing contact. That’s all good news, but sadly we doubt any amount of promising science is enough to make the pink lady go away.

No matter how hard Skype and others try to convince us otherwise, we still do most of our web communications via text or, if entirely unavoidable, by voice. Maybe we’re luddites or maybe video calling has yet to prove its value. Hoping to reverse such archaic views, researchers at the MIT Media Lab have harnessed a Kinect’s powers of depth and human perception to provide some newfangled videoconferencing functionality. First up, you can blur out everything on screen but the speaker to keep focus where it needs to be. Then, if you want to get fancier, you can freeze a frame of yourself in the still-moving video feed for when you need to do something off-camera, and to finish things off, you can even drop some 3D-aware augmented reality on your viewers. It’s all a little unrefined at the moment, but the ideas are there and well worth seeing. Jump past the break to do just that.

A professor at MIT claims to have Mother Nature beat at her own game. Dr. Daniel Nocera says his invention is ten times more efficient at photosynthesis than a real-life leaf, and could help to bring affordable alternative energy to developing countries. Described as an “advanced solar cell the size of a poker card,” the device is made of silicon, electronics, and inexpensive catalysts made of nickel and cobalt. When placed in a gallon of water under direct sunlight, the catalysts break the H2O down into hydrogen and oxygen gases, which are then stored in a fuel cell — the energy produced is apparently enough to power a single house for a day. Of course, this isn’t the first time we’ve seen scientists try to one-up nature, in fact, we’ve seen solar-powered leaves before, but this thing actually looks poised for the mass market — Nocera signed a deal with Tata in October. Full PR after the break.

Detecting cancer could be on the verge of getting a whole lot cheaper — and better. Researchers at Harvard and MIT have come up with a device that, using a needle to get a tissue sample, has achieve 96 percent accuracy despite having a cost to produce of just $200. It’s called a mini NMR (for nuclear magnet resonance) and also gives results in under an hour, giving the good or bad news on a smartphone display. The cost, simplicity, and portability could make it much easier for cancer to be caught and diagnosed early, but naturally it still has a good bit of testing left before it’ll be ready for prime time.
