World Bank report finds selling virtual goods in games more profitable than 'real' economy
A report commissioned by the World Bank's infoDev unit has cast fresh light on one of the more fascinating aspects of our brave new interconnected world: the virtual economy. The "third-party gaming services industry" -- where wealthy but impatient players have someone else grind away at online games for them in exchange for monetary reward -- is one of the focal points of the study, chiefly owing to it having generated revenues in the region of $3 billion in 2009 and now serving as the primary source of income for an estimated 100,000 young folks, primarily in countries like China and Vietnam. What's encouraging about these findings is that most of the revenue from such transactions ends up in the country where the virtual value is produced, which contrasts starkly with some of the more traditional international markets, such as that for coffee beans, where the study estimates only $5.5 billion of the $70 billion annual market value ever makes it back to the producing country. The research also takes an intriguing look at the emerging phenomenon of microwork, which consists of having unskilled workers doing the web's version of menial work -- checking images, transcribing bits of text, bumping up Facebook Likes (naughty!), etc. -- and could also lead to more employment opportunities for people in poorer nations.

Our annual data consumption estimated at 9.57 zettabytes or 9,570,000,000,000,000,000,000 bytes
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 out the report below for fuller details on the study and its methodology.
da Vinci Robot pwns Operation, deems our childhoods forlorn (video)
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. Be sure to peep the pseudo-surgery in video form below the break.
Bionic eye closer to human trials with invention of implantable microchip
We've had our eye -- so to speak -- on Bionic Vision Australia (BVA) for sometime, and with the invention of a new implantable microchip it's coming ever closer to getting the bionic eye working on real-deal humans. The tiny chip measures five square millimeters and packs 98 electrodes that stimulate retinal cells to restore vision. Preliminary tests are already underway, and clinicians are in the process of screening human guinea pigs for sampling the implants -- the first full system is still on track for a 2013 debut. In the interest of future success: here's mud in your eye, BVA! Full PR after the break.
Kinect used to make teleconferencing actually kind of cool (video)
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.
Gmail Motion April Fools' gag inevitably turned into reality using Kinect (video)
It had to happen. When Google showed off a new and revolutionary Gmail Motion control scheme yesterday, it failed to fool most people, but it didn't fail to catch the attention of some motion control geeks with Kinect cameras on hand. Yep, the FAAST crew that's already brought us a Kinect keyboard emulator for World of Warcraft has taken Google to task and actually cooked up the software to make Gmail Motion work. All your favorite gestures are here: opening an email as if it were an envelope, replying by throwing a thumb back and, of course, "licking the stamp" to send your response on its way. Marvelous stuff! Jump past the break to see it working, for real this time.
Zdenek Kalal's object tracking algorithm learns on the fly, likely to make next 007 flick (video)
Microsoft's own OneVision Video Recognizer may be novel, but if the folks in Redmond are seriously looking to take things next-level, they should probably cast their gaze across the pond. Zdenek Kalal, a researcher at the University of Surrey, has just created what may be the most sophisticated vision system known to the civilian world. In essence, it takes the mundane task of tracking objects to an entirely new platform, enabling users to select an object on the fly and have the algorithm immediately start tracking something new. Within seconds, it's able to maintain a lock even if your object twists, turns, or leaves / returns. Furthermore, these "objects" could be used as air mice if you force it to track your digits, and if you teach it what your staff looks like, you'll have a fully automated security scanner that can recognize faces and grant / deny access based on its database of white-listed individuals. Frankly, we'd rather you see it for yourself than listen to us extolling its virtues -- vid's after the break, per usual.
Carbon nanotubes used to more easily detect cancer cells, HIV
Cancer's not slowing its march to ruining as many lives as it possibly can, so it's always pleasing to hear of any new developments that act as hurdles. The latest in the world of disease-prevention comes from Harvard University, where researches have created a dime-sized carbon nanotube forest (read: lots of nanotubes, like those shown above) that can be used to trap cancer cells when blood passes through. A few years back, Mehmet Toner, a biomedical engineering professor at Harvard, created a device similar to the nano-forest that was less effective because silicon was used instead of carbon tubes. Today, Toner has teamed up with Brian Wardle, associate professor of aeronautics and astronautics at MIT, who together have redesigned the original microfluid device to work eight times more efficiently than its predecessor. The carbon nanotubes make diagnosis a fair bit simpler, largely because of the antibodies attached to them that help trap cancer cells as they pass through -- something that's being tailored to work with HIV as well. Things are starting to look moderately promising for cancer-stricken individuals, as hospitals have already began using the original device to detect malignant cells and ultimately prevent them from spreading -- here's hoping it's qualified for mass adoption sooner rather than later.
Harvard physicist puts fires out with electrified wand, hopes to share on HarvardConnection
Okay, so maybe Ludovico Cademartiri will be forced to share the good news on Facebook (or ConnectU, if he's into playing the role of rebel), but at least he's bound to see over a couple of hundred hits. According to The Harvard Crimson, the aforesaid physicist and a smattering of other researchers have stumbled upon a novel way to extinguish flames: electricity. The idea is eventually enable firefighters to squash fires without having to douse a home or object with water and foam -- if hit with a beam of juice, there's at least a sliver of a chance that something can be salvaged. While the specifics of the project are obviously far above our heads, the gist of it is fairly simple -- flames contain soot particles, which become "electrically charged during combustion." Given that those very particles react to electrical fields, a strong enough beam can twist things until it's extinguished completely. Quite honestly, it's a hands-on experience we're desperately trying to arrange, but till then, it looks like another round of Harry Potter will have to do.
Students build self-balancing TIPI robot, plan new world order (video)
Remember this guy, the QB robot that was priced at a whopping 15 grand? Seemingly, the webcam wheeler inspired a team of young minds at the University of Waterloo, who've unleashed the DIY in themselves to build one of their own. TIPI, or Telepresence Interface by Pendulum Inversion, was designed to give humans the feeling that they're not actually talking to a six-foot tall cyclops cyborg with an LCD face and webcam eye, but rather, evoke the emotions drawn when speaking the old, conventional, face-to-face way. Thanks to this team of mechatronics engineers, the low-cost TIPI uses an accelerometer, gyro and pendulum to balance by itself and can be remotely controlled while communicating via its Beagle Board and Polulu Orangutan SVP brain. Head past the break to see the robot struttin' its stuff -- oh, and get ready to rave. You'll see what we mean.
Scientists improve blue OLED efficiency, don't promise everlasting light
Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.
Researchers enable tactile feedback for e-readers using real paper, just like the olden days (video)
Brainiacs from Osaka University have created what they've called the Paranga -- a device that fulfills the lack of tactile feedback of page turns when using an e-reader. It's got a built in sensor that detects when the book is being bent and will rotate a roll of paper strips against your thumb. The force exerted against the device will control the speed of the paper roll. Although it's not accurate enough to turn one page at a time, the researches believe that if foil is used instead of paper, the voltage will be discharged as soon as a page is turned, ensuring single-page accuracy. If you want to see a video of the Paranga imitate page-turning, press play on the embed below the break.
Visualized: preconceived notions about personal computer security
See that chart up there? That's a beautiful visualization of a dozen folk models surrounding the idea of home computer security, devised by Michigan State's own Rick Wash. To construct it (as well pen the textual explanations to back it), he interviewed a number of computer users with varying levels of sophistication, with the goal being to find out how normal Earthlings interpreted potential threats to their PC. His findings? A vast amount of home PCs are frequently insecure because "they are administered by untrained, unskilled users." He also found that PCs remain largely at risk despite a blossoming network of preventative software and advice, and almost certainly received an A for his efforts.

Columbia doctors turn to IBM's Watson for patient diagnosis, clairvoyance
Who says Watson's only good for laying the smack down on former Jeopardy champions? In what can only be described as the natural progression of things, Herbert Chase -- professor of clinical medicine in Columbia's Department of Biomedical Informatics -- is working with IBM in order to retrofit the supercomputer to "help doctors diagnose and treat patients." According to Chase, this level of robot practice has been impossible for the past score or so, and if the experiment works, Watson could serve to provide physicians "immediate, accurate answers to unusual, head-scratching questions that come up in their daily practice and do so based not only on the latest published research, but also the blogosphere." In other words, Watson could rapidly collect and analyze up-to-date published data from a near limitless amount of online sources, and then use that knowledge to recommend suggestions that a seasoned M.D. may never consider. Furthermore, Chase sees tremendous potential for Watson in the realm of personalized medicine; considering that two patients with the same diagnosis won't necessarily react to treatments the same way, Watson could come up with alternatives on the fly. There's no clear indication of when the testing will wrap up, but see how far you get next time you're in the emergency room by inquiring about Dr. Watson's availability.
Texas researchers aim to solve wireless bandwidth bottleneck, hopefully before SXSW 2012
As anyone attempting to stream high-quality video on any major metropolitan subway has likely found, doing so often requires the patience of Job and a willingness to spend more time 'buffering' and less time 'enjoying.' It's a problem that's particularly evident at crowded events like the never-ending South by Southwest, and it's probably no coincidence that a team from The University of Texas at Austin are now spending their waking hours attempting to solve the looming wireless bandwidth crisis. Five faculty in the school's Electrical and Computer Engineering Department have been selected to receive a $900,000 gift from Intel and Cisco to "develop innovative and novel algorithms that could improve the wireless networks ability to store, stream and share mobile videos more efficiently." Their work is part of a five university tie-up, seeking to solve quandaries such as tower interference, selective compression (read: pixelating the areas you don't pay attention to in order to squeeze more out of the existing infrastructure), cell tower intelligence and data output redundancy. Hard to say if any of the major carriers will be implementing proposed solutions in the near future, but we can think of at least one company that's crossing its fingers in hopes of that very outcome.
Researchers claim discovery of lost city of Atlantis, conveniently located in southern Spain
We had to do a double take when we read this headline from Reuters, but sure enough, it's not April1st yet and its writers don't seem to be joking: the location of the lost city of Atlantis has finally been discovered. Such is the bold claim from an international team of researchers, dreamers and intrepid adventurers. With the use of ground-penetrating radar and electrical resistivity tomography, they've unearthed evidence to suggest that a spot on the southern coast of Spain, just north of Cadiz, played host to what may have been human society's first metropolis. One of the reasons why it's taken archaeologists so long to pinpoint its whereabouts may be the fact that it lies 60 miles inland, where you wouldn't really expect it to be susceptible to the effects of tidal waves (which is what Plato's account of the ancient city identified as its demise). A National Geographic documentary on the subject will be broadcast this evening where we may learn more about what was discovered, the methods for doing so, and the gorgeous tans those scientists built up in sunny Spain.
Northwestern University researchers route photon qubit, make quantum internet possible
Big brains across the globe continue to unlock the secrets of the qubit and harness it for myriad uses -- quantum hard drives, quantum computers, and even quantum refrigerators. The internet may be next in line to get quantum-ized now that researchers from Northwestern University found a way to route a photon qubit through an optical cable without losing any of its physical characteristics. A newly developed optical switch does the deed, which allows fiber-optic cables to share multiple users' quantum info at once -- making superfast all-optical quantum communication networks possible -- and gets us closer to having our tweets and status updates whizzing to and fro at the speed of light.

Apple exchanges iPads for iPad 2 for Rutgers class
An Apple retail store in New Jersey has taken back an order of original iPads and replaced them with iPad 2 units for a class at Rutgers' Center for Management Development, according to Forbes. In a move bound to annoy everyone who bought an iPad just before the iPad 2 was released and found that it was too late to return it, Apple isn't even charging a restocking fee even though the iPads had already been customized. The class was scheduled to start shortly before the iPad 2's release date on March 11, so the school had gone ahead and purchased the tablets (the students actually pay for them and keep them after the class is over). The article doesn't say exactly how this deal was arranged, but it's safe to say that someone at Rutgers followed my mom's perennial advice, "If you don't ask, the answer is no," and made a phone call to the local Apple Store. From the article, it is clear that Rutgers has a regular cycle of classes that use the iPads, which no doubt made it a little easier for Apple to show such extra flexibility. Of course, no good deed goes unpunished, so I'm sure there will be a whole host of people complaining that they didn't get the same offer. If you did happen to order an iPad recently, it's definitely worth a visit to your local Apple Store or a polite call to Apple support. Just remember, you're not a university sending tens of thousands of recurring dollars to Apple, so don't be too surprised if you don't get the same deal. [via The MacObserver]
Optical tweezers manipulate microscopic objects using an iPad, raw brainpower (video)
Okay, so maybe the whole brainpower thing is a distant second to the iPad itself, but still -- being a rocket scientist probably doesn't hurt when manipulating microscopic objects via a multitouch display. That's the kind of setup that students and boffins alike have going at England's University of Bristol, where iTweezers are being used to control a tiny rod about 300 nanometers wide, amongst other things. Essentially, the iPad is able to display what's under a microscope via a wireless display transfer, and then, touch points are converted into laser movements that are used to handle objects that are far smaller than those visible particles clogging up your left ear right now. All told, a user can select up to 11 different objects, and in theory, the iPad could enable scientists to do this remotely. Hey, we're all about new and improved ways to telework. Vid's below, kiddos.
Ball-throwing robot seal has a talent for basketball, embarrassing humans (video)
You pick up your first tan leather roundball at the age of 9, you practice religiously for a decade before you can even feel worthy of calling yourself a basketball player, and then you find a video online of a robotic seal that can shoot better than you after just a few weeks in the lab. Yep, some Taiwanese know-it-alls have put together a robo-seal that converts 99 percent of shots (admittedly with a toy ball launched at a toy hoop) within a three-meter range. It's basically just an articulating arm with stereo vision for some good old depth perception, but it's sophisticated enough to maintain its killer accuracy even if the target is moved from its spot. That's more lethal that Shaq or Karl Malone's elbows ever were. Video's after the break, skip to the 1:05 mark if you don't care about the details of how it's done.
