MIT working up microbatteries to power implantable medical sensors
In the never-ending quest to make even the smallest devices on Earth a touch smaller, a talented team of MIT engineers have developed a method for creating and installing microbatteries, which could eventually power a plethora of diminutive devices including "labs-on-a-chip and implantable medical sensors." It's bruited that this is the first time in which "microcontact printing has been used to fabricate and position microbattery electrodes and the first use of virus-based assembly in such a process," and while you'd likely have to be a colleague to even digest that, the take away is that these gurus are one step closer to generating battery-powered Scrubbing Bubbles. And your shower could use 'em.[Via PCMag]
MBTA affirms that vulnerabilities exist, judge lifts gag order on MIT students
No surprise here, but the kids from MIT were (presumably) right all along. The three students who were muffled just before presenting their case at Defcon have finally been freed; the now-revoked gag order had prevented them from exposing insecurities in the Massachusetts Bay Transportation Authority ticket system, but during the same court setting, the MBTA fessed up and admitted that its current system was indeed vulnerable. Of note, it only confessed that its CharlieTicket system was susceptible to fraud, while simply not acknowledging any flaws in the more popular CharlieCard option. Pish posh -- who here believes it doesn't have dutiful employees working up a fix as we speak?
Defcon duo: how-to shut off a pacemaker, almost get free rides on the T
Defcon already delivered by exposing California's FasTrak toll system for the security hole that it is, but that's not nearly all that's emerging from the Las Vegas exploitation conference. For starters, a plethora of medical device security researchers have purportedly figured out a way to wirelessly control pacemakers, theoretically allowing those with the proper equipment to "induce the test mode, drain the device battery and turn off therapies." Of course, it's not (quite) as simple as just buzzing a remote and putting someone six feet under, but it's a threat worth paying attention to. In related news, a trio of MIT students who were scheduled to give a speech on how to hack CharlieCards to get free rides on Boston's T subway were stifled by a temporary restraining order that the Massachusetts Bay Transit Authority snagged just before the expo. Don't lie, you're intrigued -- hit up the links below for all the nitty-gritty.Update: MIT published the Defcon presentation in a PDF.Read - Pacemaker hackRead - Massachusetts Bay Transit Authority sues MIT hackersRead - Restraining order on said hackers
MIT conjuring up 6D "super-realistic" image system
2008 has been somewhat of a banner year for 3D, but the brilliant minds at MIT are already working up a system that'll put U23D to shame. Hailed as a "super-realistic image system," the invention produces "6D" images that not only have a full three-dimensional appearance, but also "respond to their environment, producing natural shadows and highlights depending on the direction and intensity of the illumination around them." Without relying on electronics or active control, the process could be used to produce images with an "unprecedented degree of realism" -- resulting in something associate professor Ramesh Raskar calls the "ultimate synthetic display." As expected, initial applications for the ultra-pricey ($30 per pixel, currently) system revolve around digital signage / advertising, but it's really just a matter of time before Six Dimensions of The Jonas Brothers hits a cinema near you. Save us.
Ear-A-Round headsets keep tabs on cows, make farming easier
In no way are we insinuating that farming is ever "easy," but a new headset designed for cows could make cattle herding a much less stressful experience. The Ear-A-Round headsets are the product of a project involving the USDA and MIT, and essentially, the GPS-infused devices would transmit stereo sounds directly in a bovine's ears in order to guide and direct his / her movements. Strange though the head-worn gizmos may look, the built-in solar panel should keep it juiced up and ready to dictate on command, giving farmers the ability to track and herd from the comfort of their computer desks. The overriding goal here is to "improve animal distribution on the landscape," though we can think of quite a few other positives to having such a robust virtual fencing system.[Via Core77]
Move over, OLPC -- the $12 Apple II-based PC is coming
Alright, so it won't be a laptop, adorable, or have a cheeky Linux-based OS that's eventually replaced by Windows, but unlike the OLPC or the too-good-to-be-true $10 laptop, the $12 PC currently being developed at MIT will probably hit its price target. The project, being spearheaded by Derek Lomas and Jesse Austin-Breneman, is centered around cheap Apple II-based machines currently on sale in India and other developing nations that plug into televisions, and the goal is to update the systems with more memory, web access through cellphone tethering and actual storage. Considering we've already seen Apple IIs updated with Bluetooth and USB, and the less-powerful Commodore 64 can be used at LAN parties, we'd say all that stands between this project and reality is manpower -- any Apple II hackers out there ready to help?
Video: MIT develops solar storage "nirvana": energy crisis solved?
MIT is in a twisted, propeller-capped knot this morning heralding a new discovery it says will unleash a solar revolution. However, the "revolutionary leap" inspired by photosynthesis is not on the glamorous front-end of energy collection, rather, it's related to a simple, highly efficient and inexpensive way to store that energy when the sun doesn't shine. "This is the nirvana of what we've been talking about for years," says Daniel Nocera, MIT neomaxizoomdweebie who with Matthew Kanan developed the unprecedented approach to split water into hydrogen and oxygen gases using the sun's energy. The gases can then be recombined later inside a fuel cell. The key components to the process are a pair of catalysts (one consists of cobalt metal, phosphate, and an electrode; the other, platinum) which produce the O and H gases at room temperature and in neutral pH water (i.e., tap water). While similar solutions exist for industrial use (primarily), these are very expensive and require specialized environments. "This is a major discovery with enormous implications for the future prosperity of humankind," said James Barber, a leader in the study of photosynthesis at Imperial College in London. "The importance of their discovery cannot be overstated since it opens up the door for developing new technologies for energy production thus reducing our dependence for fossil fuels and addressing the global climate change problem." Nocera concedes that further engineering is required to commercialize the approach but hopes to see it implemented in household fuel cell systems within the next 10 years.

iShoe promises to detect balance problems before it's too late
There's plenty of devices out there designed to keep folks from falling over, but this so-called iShoe developed by some MIT researchers takes a slightly different tact, with it promising to detect balance problems long before a person actually falls. That's apparently possible thanks to some sensor-laden insoles that measure the pressure distribution across as person's feet, which can be offloaded onto a computer and analyzed with the aid of a special algorithm the researchers have created. Eventually, they say the system could let doctors catch balance problems in their early stages and take the appropriate action, or even notify family members if a person falls, although that latter bit doesn't exactly seem very optimistic of them. No word on a commercial release just yet, but the team is apparently moving steadily towards one, with it currently conducting trials and recently having snapped up a $50,000 grant to help cover start-up costs.
MIT researchers develop window-tint solar concentrators
No, the blacked-out rear quarters of your '90 CRX aren't going to start powering your hooptywoofer anytime soon, but a new window treatment developed at MIT that functions as a solar concentrator promises to finally bring solar windows to the masses. Based on similar work done in the '70s, the dye mixture pulls in light at a range of wavelengths and re-emits it to solar cells at the edges of the window at a different wavelength -- a technique good for a 40x increase in each cell's power output, or 10 times what current systems can provide. The team estimates that the panels could become widely commercial within three years -- just in time for us to bolt 'em onto our new solar shoe Prius.[Via Metaefficient and TechNewsWorld]
Tools of the trade: Scratch for SL
MIT Media Lab's Eric Rosenbaum has produced a wonderful little tool called Scratch for Second Life (S4SL). Available for Mac or Windows (but not Linux at present, alas) S4SL allows you to create scripts by assembling simple colorful shapes (a bit like plastic bricks). S4SL is based on MIT's Scratch, and allows you to put together some useful functionality very simply. S4SL isn't going to make you a star creator of scripts overnight, though -- anyone who knows Second Life's LSL scripting language and has a modicum of programming skill can do much more, but that's not the point here.
MIT solar dish holds promise for low-cost energy production
Look out 1366 Technologies, you've got yet another solar-based MIT spin-off company vying for business in the alternative energy sector. The company's name is RawSolar, and in due time it could end up selling solar dish arrangements that could power factories or even heat / cool office buildings. Recently, a team of students and faculty celebrated as a prototype dish proved that it could concentrate sunlight by a factor of 1,000, which obviously bodes well for converting that into useful energy here on Earth. Another standout feature of the dish is its small size, and furthermore, the material required to build it is relatively inexpensive and accessible worldwide. Sounds like all the ingredients for a successful startup are there, now we've just got to wait and see if anything becomes of it. We're watching you, RawSolar -- don't let us down.[Thanks, Spencer]
MIT fabricates nanowire mats to selectively absorb oil
A team of astute MIT researchers have developed a sophisticated new material that could help control, contain and lessen the environmental impact of future oil spills. The creation is a mat of nanowires that actually looks a lot like paper, but unlike the material your paycheck gets printed on, this stuff can "selectively absorb hydrophobic liquids (oil-like liquids) from water." We're talking about a membrane that can "absorb up to 20 times its weight in oil, and can be recycled many times for future use." Outside of this, it could also be used in water filtration processes and for designing the next great wetsuit. Okay, so we're making that last one up, but don't dare say it's beyond the realm of possibility.[Via NewScientist]
Swarm robotics project further ensures our doom
Much to our dismay, this isn't the first swarm project that really makes us wonder how long humans will be running things on Planet Earth. MIT's own James McLurkin was recently down in Austin, Texas showing off a dozen or so of his hundred (is that even legal?) robots. The group was reportedly able to spread out, clump together, play follow the leader and circle the wagons, all of which were just ploys to distract us from seeing precisely how much they really know. Each of the appropriately-titled SwarmBots featured eight AA batteries, a 1.1-watt speaker, behavior LEDs, a radio, camera and an IR communications system. For those curious, each one cost around $2,000 to build, but Mr. McLurkin suggested that these were a bargain compared to typical research bots. It's all about perspective, baby.[Via Futurismic]
MIT uses Macs to learn how children gain speech skills
Apple's Science page has a profile up for the folks over at the Massachusetts Institute of Technology -- apparently two MITers, Deb Roy and Rupal Patel, are using Macs, including "five Apple Xserves and a 4.4TB Xserve RAID," to record and track every single moment of their son's early childhood.Not only are they assured to get his first few steps on tape, but they're also studying early development and how young children gain the skills to interact with other human beings. In order to do this, they're dealing with huge amounts of audio and video data -- about 250TB. And they're also building an analysis application on the platform called TotalRecall to scan through all the audio and video and pick out interesting parts and patterns (creating the kind of image seen above -- apparently that means something to them).Of course, there is one thing they do that Apple can't -- when the time came to figure out how to transfer 200GB a day from the home environment to work, they eventually settled on a "sneakernet" approach, packing up the digital tapes in a case and carrying them to work. Here's hoping Apple will announce their own proprietary version of iSneakernet at the next WWDC (with a stylish design and a reasonable pricetag, of course).
MIT reinvents the Post-It note... with Post-It notes
We've seen countless attempts to re-invent the Post-It note, but no one's ever really managed to improve on the basic design -- which might be why MIT's "Quickies" concept doesn't even try. The electronic note system is instead based around a digital pen and special pad, which saves your notes as you jot them down on RFID-embedded Post-Its. Software on your PC then does some quick OCR and, according to the inventors, "uses its understanding of the user's intentions, content, and the context of the notes to provide the user with reminders, alerts, messages, and just-in-time information." Since the database can also store location information, sticking the note on a book or other object allows you to locate it later using the RFID tag, and you can even have notes SMS'd to their recipients. Pretty wild -- but we're more impressed someone finally found a good use for all those digital pens out there. Check a video of the system in action after the break.
MIT researcher aims to understand language with Human Speechome Project
It's far from the first time a researcher has enlisted the help of his own family or kids, but MIT's Deb Roy's latest endeavor looks to be a bit more ambitious than most, as he's aiming to do nothing short of understand how children learn language. To do that, Roy and his wife installed 11 video cameras and 14 microphones throughout their house to record just about every moment of their son's first three years. That, obviously, also required a good deal of computing power, which came in the form of a temperature-controlled data-storage room consisting of five Apple Xserves and a 4.4TB Xserve RAID (you can guess why Apple's profiling 'em), along with an array of backup tape drives and robotic tape changes (and an amply supply of other Macs, of course). While the project is obviously still a work in progress, they have apparently already developed some new methods for audio and video pattern recognition, among other things, and it seems they'll have plenty of work to sift through for years to come, with the project expected to churn out some 1.4 petabytes of data by the end of year three.[Thanks, Jeff]
MIT's Nexi bot wants to be your friend
MIT is really taking its robotics program to a whole new level with its "MDS" platform, which stands for Mobile, Dexterous and Social. The flagship bot so far is Nexi, who certainly fits the bill, albeit with an extra dab of creepy. The bot stands on a Segway-esque wheel base, has articulated arms and hands, and can convey a wide range of emotion with that pasty white face. Nexi has a computer on board to manage sensors and instinctual responses, while it offloads the heavy duty AI work to a stationary computer over the network. MIT's eventual goal is to have Nexi and others participate in Socially Situated Robot Learning -- observing and interacting with humans to figure out how best to integrate with them. Don't worry Nexi, we like you for you. Video is after the break.[Via fresh creation]
MIT spin-off 1366 Technologies touts better, cheaper solar cells
In what's become an increasingly familiar tune, a startup company has announced that it's just pulled in a significant haul of funding based on its promises of better, cheaper solar power. In this case, the company in question is 1366 Technologies, which was spun out of research from MIT and is headed by MIT professor Ely Sachs (who is taking a leave of absence to focus on the company). According to the company, it's found a way to make solar cells from multicrystalline silicon that are just as efficient as ones from single-crystal silicon, which is normally much more expensive to produce. In terms of hard numbers, that translates to solar cells that are 27 percent more efficient than your average solar cell, and (in its current state) a cost a $2.10 per watt. Sachs says that cost will come down to $1.65 per watt when manufacturered on a commercial scale, however, and will eventually drop to $1.30 a watt with some "planned improvements." That's still short of the $1 a watt goal they're aiming for (which is roughly the cost of coal), but the company seems confident they can hit that mark by 2012 with some "anticipated advances."[Via Physorg]
MIT's Siftables let you juggle your data... for real
The cats and kittens at the MIT Media Lab are always on some next-level type of wackiness, and the Siftables project doesn't break from that trend. The concept seems simple enough: a collection of small, self-contained input / display devices wirelessly link together to form an independent mini-network, or a control system for a PC. The cubes feature OLED screens, a 3-axis accelerometer, Bluetooth, flash memory, and a haptic actuation driver, and feature additional ports for attaching other devices. The aim is to create a more natural system for handling and displaying data, though we won't be surprised if this is somehow incorporated into an even more realistic version of Call of Duty. Check out the video after the break to see the little guys in action.[Via OhGizmo!]
Bio-electronic implant seeks to restore partial sight
We've seen initiatives all over the globe created in an attempt to beat blindness, but researchers based at MIT are feeling fairly confident that their development is within a few years of being able to "restore partial sight to people who have slowly gone blind because of degenerative diseases of the retina." The bio-electronic implant, which is about the size of a pencil eraser, would actually sit behind the retina at the back of the eyeball, and images would be transmitted to the brain "via a connector the width of a human hair." As it stands, an FDA grant application is already in the works, and the scientists are hoping to have it implanted in an animal as early as this summer. Still, the solution only works for folks who "were once able to see and have partially intact optic nerve cells" -- those who were blind from birth or suffer from glaucoma are unfortunately ineligible for the procedure.[Thanks, Rusty]
