MIT gestural computing makes multitouch look old hat

Ah, the MIT Media Lab, home to Big Bird’s illegitimate progeny, augmented reality projects aplenty, and now three-dimensional gestural computing. The new bi-directional display being demoed by the Cambridge-based boffins performs both multitouch functions that we’re familiar with and hand movement recognition in the space in front of the screen — which we’re also familiar with, but mostly from the movies. The gestural motion tracking is done via embedded optical sensors behind the display, which are allowed to see what you’re doing by the LCD alternating rapidly (invisible to the human eye, but probably not to human pedantry) between what it’s displaying to the viewer and a pattern for the camera array. This differs from projects like Natal, which have the camera offset from the display and therefore cannot work at short distances, but if you want even more detail, you’ll find it in the informative video after the break.

Spin polarization achieved at room temperature, elusive miracles now less elusive
Spintronics — much like Cook-Out milkshakes and cotton candy for all — seems like a pipe dream at this point. We’ve been beaten over the head with theoretical miracles, but we’re getting to the point where it’s put up or shut up. Thankfully, a team of Dutch boffins are clearly in the same camp, and they’ve been toiling around the clock in order to achieve spin polarization in non-magnetic semiconductors at ambient temperature. The amazing part here is that “temperature” bit; up until this discovery, spin polarization was only possible at levels of around 150 K, or at temperatures far, far cooler than even your unheated basement. If spintronics could effectively be enacted at room temperature, all those unicorn-approved phenomena we mentioned earlier would have a much greater chance of sliding into the realm of reality. Here’s hoping they get this stuff ironed out prior to 2012.

Mizzou’s nuclear battery to power things smaller than your brain can imagine
Oh yeah, everyone loves the extended battery, but are we really kosher with the added bulge? A team of boffins at the University of Missouri certainly aren’t, as they’ve spent the last good while of their lives researching and developing a new nuclear battery that could be used to power devices much smaller than, well, most anything. The radioisotope cell, as it’s called, can reportedly “provide power density that is six orders of magnitude higher than chemical batteries,” and while some may question the safety of this potentially volatile device, the liquid semiconductor (used instead of a solid semiconductor) should help ease concerns. The current iteration of the device is about the size of a penny, and it’s intended to power a variety of MEMS systems. Now, if only these guys could find a way to make a standard AA last longer than a week in our Wiimote, we’d be pleased as punch.

Colored solar panels work without direct sunlight, double as PAR Can filters
With eco-friendliness on everyone’s mind, it’s no shock to see more and more progress being made in the realm of solar. Shortly after hearing that boffins across the way were swapping carbon nanotubes for silicon, a Tel Aviv-based startup is now hoping to push its colored panels into the mainstream thanks to their ability to work sans direct sunlight. Granted, the tinted cells have only shown a 12 percent efficiency rate in testing, but they can reportedly be produced for around half of what a conventional panel costs. In essence, the cost savings comes from the dearth of silicon within, as GreenSun Energy has discovered that power can be generated by simply diffusing available sunlight over the whole panel and allowing nanoparticles to handle the rest. We’ll invite you to visit the links below for the science behind it, but we’re just interested in helping Ma Earth while replacing every windows in our apartment with a stained glass alternative.

Transparent aluminum! Would that be worth somethin’ to ya, eh?

It’s hard to say if boffins at Oxford University got their inspiration from Nimoy and Co., but one thing’s for sure: they aren’t joking about the creation of transparent aluminum. In what can only be described as a breakthrough for the ages, a team of mad scientists across the way have created “a completely new state of matter nobody has seen before” by blasting aluminum walls (around one-inch thick) with brief pulses of soft X-ray light, each of which is “more powerful than the output of a power plant that provides electricity to a whole city.” For approximately 40 femtoseconds, an “invisible effect” is seen, giving the gurus hope that their experiment could lead to new studies in exotic states of matter. For a taste of exactly what we mean, feel free to voice command your PC to jump past the break. Or use the keyboard, if you’re feeling quaint.
