What's better than billions of transistors? Billions of miniature two-nanometer ones, leaving room for billions more. A team of researchers accomplished just that, using the quantum effect to shrink these semiconductors -- and set a new size record in the process -- while also managing to keep them operating at room temperature (note: that photo above is from a different team's study). The team of South Korean, Japanese, and British researchers at Chungbuk National University expect them to "enhance the capabilities of mobile electronic devices" -- a mighty vague claim if ever there was one. Not one for modesty, lead researcher Choi Jung-bum proclaims that it "effectively changes the paradigm of such devices." With no word on mass production, though, we'll just have to wait and see for ourselves how big of an impact these lilliputian circuits will have.  Yonhap News ,  Tech-Freak Stuff

There are a few robots smart enough to solve a Rubik's Cube in seconds flat, but a group of students at Swinburne University of Technology think theirs may be the fastest on Earth. Their bot, named Ruby, recently mastered the puzzle in just 10.69 seconds, including the time spent analyzing the cube. To achieve this feat, the device scanned the toy with a webcam before its software processed the images to crank out a solution. According to the university, Ruby's 10-second mark smashes the current world robot record of 18.2 seconds, unofficially making it the fastest cube-solving machine on the planet. But Ruby still has a long way to go before it catches Feliks Zemdegs -- a 16-year-old Australian who solved a Rubik's Cube in 6.24 seconds and continues to carry the torch for all of humanity. Twist and turn your way past the break for the full PR and a video of Ruby in action, as well as a clip of Zemdegs showing us how the pros do it.

Why would a group of researchers develop a table full of rods that mimic the movements of microscopic hairs? It's a fair question, and Keio University's Yusuke Kamiyama certainly doesn't offer up much in the way of real world applications for such technology. He is, however, happy to demonstrate the cool functionality of the metallic cilium, which appear to drift around as though underwater, until coming into contact with an external stimuli. The rods react to touch by congregating near the area of contact, with movements executed by biometal rods that communicate with an external PC. Scientists hope that research from the project will be useful at some point, but in the meantime, at least we know where to turn if we get a major mucus blockage. Video after the break. DigInfo

Remember when you didn't consider climbing trees a chore? Treebot doesn't -- but then, it wasn't programmed to know boredom. The robot was designed by a team at The Chinese University of Hong Kong for the express purpose of shimmying up trees autonomously, figuring out the best route up a trunk using built-in touch sensors. The 'bot's body is designed like an inchworm, expanding and contracting as it works it way up -- unlike other climbers we've seen. Treebot can carry up to 3.7 pounds as it inches along, opening up the possibility of using the machine to prune hard to reach leaves. It can also shuffle up a variety of different plants, including bamboo stems, as evidenced by the sped-up video after the break. Unwieldy foliage, you've been put on notice.

We always knew that Watson's powers extended well beyond the realm of TV trivia, and now IBM has provided a little more insight into how its supercomputer could help doctors treat and diagnose their patients. Over the past few months, researchers have been stockpiling Watson's database with information from journals and encyclopedias, in an attempt to beef up the device's medical acumen. The idea is to eventually sync this database with a hospital's electronic health records, allowing doctors to remotely consult Watson via cloud computing and speech-recognition technology. The system still has its kinks to work out, but during a recent demonstration for the AP, IBM's brainchild accurately diagnosed a fictional patient with Lyme disease using only a list of symptoms. It may be another two years, however, before we see Watson in a white coat, as IBM has yet to set a price for its digitized doc. But if it's as sharp in the lab as it was on TV, we may end up rememb

We have to admit, we never thought of this one -- and it's pretty, pretty slick. Instead of using time-coded vinyl to interface your turntable with your computer as with Final Scratch Pro or Serato Scratch, Nicholas J. Bryan's Mopho DJ uses an iPhone. That's right, our man at Stanford University literally affixes his smartphones to his decks via a perspex disc and some sort of adhesive. The smartphones each run an app which sends accelerometer and gyroscope data to a computer, which then adjusts playback of your music accordingly. It's still a work-in-progress at the moment, but if you're in Oslo the first week in June make sure you check it out at the NIME (New Interfaces for Musical Expression) conference. This is definitely the kind of iOS location tracking we can get behind! Check it out on video after the break. SlashGear Stanford University

You've got to hand it to Tokyo's University of Electro-Communications, the school's researchers have presented some truly unique methods for interfacing with our electronics -- fake finger sliding, a head-mounted video display, a thing that makes it feel like you've got insects on your palm, and, of course, the old kissing machine. A few recent inventions have expanded the latter trend, giving us creative new ways of getting intimate with our machines. There's the tickle interface, for one, which beams images from a connected smartphone creating the illusion that the person on the other end is tickling your palm -- made all the more real by tactile vibration hooked up to the rear of the device. And then there's the older, oddly-named Sense-Roid, sort of a clunkier version of the Hug Shirt, which, among other things, lets you "hug yourself." Both are demonstrated in a pair of videos after the break. Whatever you do, don't miss the second one.

This comes from the same touchy-feely Kajimoto lab in Japan that brought us the tactile kiss transmission device and we totally see where they're going with it: maximum sensation, minimum effort. You only have to exert the gentlest of pressures on this prototype touch pad and it zaps your fingertip with little electrical signals, mimicking the feeling of sliding your finger over a surface. We imagine it's a bit like the little red pointing stick in the middle of a Lenovo ThinkPad keyboard, for example, but with the addition of "position-dependent data input" to create the illusion that your finger is actually touching different areas of the screen. For now though, if you don't mind stretching a finger to your old-stylee mouse or trackpad, then check out the video after the break. DigInfo TV

The internet is a mighty big place that's only growing larger each day. That makes it a perfectly unwieldy thing to measure, but the traffic it generates has nonetheless been subjected to a rigorous estimation project by a group of UC San Diego academics. Their findings, published online this month, reveal that in 2008 some 9.57 zettabytes made their way in and out of servers across the globe. Some data bits, such as an email passing through multiple servers, might be counted more than once in their accounting, but the overall result is still considered an under -estimation because it doesn't address privately built servers, such as those Google, Microsoft and others run in their backyards. On a per-worker basis (using a 3.18 billion human workforce number), all this data consumption amounts to 12GB daily or around 3TB per year. So it seems that while we might not have yet reached the bliss of the paperless office, we're guzzling down data as if we were. Check

What happens when a robot with immaculate dexterity comes to grips with a notorious board game from our childhood? Just ask Johns Hopkins University students, who successfully removed the wish bone from an Operation board using the da Vinci Robot. If you're familiar with the game, you'll know how incredibly difficult it was to prevent that ear-piercing noise from occurring-- even with our tiny fingers. Of course, we should have expected that a robot -- especially one capable of folding a tiny paper airplane -- would be able to accomplish this feat with such ease.

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. Kinected Conference (MIT Media Lab)
