New microscope allows live 3D imaging of cells
Top level researchers and high-school science students alike have long been restricted by the tradeoffs of traditional microscopy: either you can look at live cells at low resolutions, or you can stabilize your sample and see some more detail. A new technique developed at MIT aims to change that, though, enabling scientists to look at live cells at high resolution -- in 3D. The microscope, which was developed by professor Micheal Feld and his team, generates images by analyzing how different parts of the cell refract light, and combines those images from different angles to create 3D models in real time. The unit has already been used at Harvard Medical School, and based on our struggles to see anything under the 'scope in college, we foresee quite a few students and professors clamoring for these at universities everywhere soon.
MIT gurus developing mechanical fin for autonomous submarine
While we've already witnessed robotic submersibles take on fish-like sensing abilities, a team at MIT is hoping to equip autonomous underwater vehicles (AUVs) with a mechanical fin in order to nix the necessity of a propeller. In essence, the crew is looking to "create a more maneuverable, propeller-less underwater robot better suited for military tasks such as sweeping mines and inspecting harbors," and they are taking a note from the bluegill sunfish to make it happen. This particular creature sports a "distinctive swimming motion which results in a constant forward thrust with no backward drag," making it the ideal candidate to replicate. Current prototypes are being constructed with a "thin, flexible material that conducts electricity," and while we've no idea when the gurus plan on cranking out a finalized version, they've already got plans to study other aspects of the sunfish's movement in order to better design the bots.[Via Physorg]
iWalk to release PowerFoot One prosthetic foot
It looks like some researchers at MIT and Brown University are about to see the fruits of their labor become commercially available, with upstart iWalk set to release the PowerFoot One prosthetic foot jointly developed by the two. Unlike similar devices, the PowerFoot One uses "tendon-like" springs and an electric motor to help propel the person forward, which supposedly reduces fatigue, improves balance and gives the wearer with a more fluid gait. A mix of sensors and specialized control algorithms also ensure that the person stays balanced while walking on slopes or stairs. While there's no word on what it'll cost, it should be commercially available sometime next summer.[Via Gadget Lab]
MIT researchers develop stylish space BioSuit
While it's far from the first attempt at a new and improved spacesuit, this so-called BioSuit from a team of researchers at MIT is certainly a lot more fashionable than some suits we've seen, not to mention a whole lot more manageable for the person wearing it. In addition to giving the astronaut greater movement, the BioSuit also promises to increase safety (with punctures able to be quickly patched), and give the wearer a workout through the use of varying resistance levels. Of course, it'll still be earthbound for quite a while, although the researchers say it should be ready in about ten years or so, potentially making it a candidate for the first human expedition to Mars.[Via Monsters and Critics, photo courtesy of MIT]
Zaragoza World Expo to feature MIT-designed "digital water" walls
While it might not quite match the robot invasion of the 2005 World Expo in Aichi, Japan, it looks like Zaragoza, Spain's 2008 World Expo won't be lacking for displays of technology either, with an MIT-designed "digital water pavilion" greeting visitors at the entrance. While its practicality may be in question, the pavilion certainly looks to be impressive enough, boasting computer-controlled walls of water that can display scrolling text or images, or automatically form a doorway when it detects a person approaching. To manage that feat, the MIT engineers employed a series solenoid valves that can be opened and closed at high frequency, effectively working, as MIT describes it, "like an inkjet printer on a large scale." It's also apparently not as wasteful as it seems at first glance, relying entirely on recycled water, with the water also eliminating the need for air conditioning.[Via PhysOrg]
MIT's wireless electricity demoed, dubbed WiTricity
We always knew Tesla was right: MIT physics professor Marin Soljacic and his team of researchers behind the latest wireless electricity scheme have reportedly demoed their magnetically coupled resonator technology on a 60-watt lightbulb that wasn't plugged in. Of course, no technology should be without a name, and so they've dubbed it WiTricity. Apparently Soljacic thinks it's possible to commercialize WiTricity within the next few years, which would be totally amazing if it was powered by Steorn's humanity-saving infinite energy device.

Robotic AUR desk lamp doubles as collaborative lighting assistant
If you've just not been in the DIY spirit of late, and would rather your lamp console you than just brighten up your surroundings, the AUR desk lamp should do the trick. Concocted as part of a Ph.D thesis on human-robot fluency and nonverbal behavior, the robotic desk lamp "serves as a non-anthropomorphic robotic platform," and was conceived around a 5-DoF robotic arm to "evoke a personal relationship with the human partner without resorting to human-like features." The so-called objective lamp seeks to "explore the relationship that can be maintained through abstract gestures and nonverbal behavior alone," and is animated using a "custom pipeline enabling the dynamic control of behaviors authored in a 3D animation system." A lot of fancy phrasing, we know, so click on through to catch it on video and let things sink in.[Via Pasta and Vinegar]
MIT's handheld FAR-NDT device sees cracks in structures
We've already seen radars come in handy when dodging impending attacks and avoiding accidents, but researchers at MIT are utilizing the technology to make sure our roadways and structures aren't pushed beyond their limits. A newfangled handheld device uses FAR-NDT (far-field airborne radar nondestructive testing) in order to "see through the fiberglass-polymer wrapping often used to strengthen aging concrete columns to detect damage behind the wrapping not visible to the naked eye." Furthermore, the technique can be executed from about 30 feet away and "requires no dismantling or obstruction of the infrastructure" in order to provide instant feedback. Unsurprisingly, creators are suggesting that it will be best used on bridges and piers which are typically difficult to carefully inspect, and while there's no word on when this stuff will hit DOT offices nationwide, current prototypes are panning out quite well.[Via Physorg]
Scratch teaches game programming, commenting etiquette
We here at Joystiq are big proponents of teaching via video games. That's why we were happy to stumble across Scratch, a super simple programming language created by researchers at MIT. Using an incredibly intuitive drag-and-drop interface, Scratch gives you all the tools you need to make simple interactive Java applets, complete with graphics and sound, without any advanced programming knowledge.How easy is it? To find out, we put together the simple program shown above. It took about an hour, and that's without even reading the FAQ or watching the handy instructional movies. In fact, the biggest time expenditure was coming up with comments that would actually be useful and helpful to our readers. Like we said, we're big proponents of teaching via video games.[Via The Tech Savvy Educator]
MIT researchers develop speedy retina scanner to diagnose ocular diseases
Although the mere mention of "retinal scanner" may get the blood boiling in privacy advocates, the latest such device out of MIT sports a much more innocent soul. Researchers at the school have reportedly developed a method to "scan the retina at record speeds of up to 236,000 lines per second, or ten-times faster than current technology." This process will allow doctors to snap "high detailed 3D images of the eye," which can be used to non-invasively spot ocular diseases such as diabetic retinopathy, glaucoma, and age-related macular degeneration much earlier and more accurately. The process itself is dubbed optical coherence tomography (OCT), and while things seem to moving along as scheduled, it will still be "five years or more" before we see this thing commercialized.[Via MedLaunches]
Quantum cryptography kinda sorta hacked
It's always only a matter of time. A little less than a year after the first quantum cryptographic network was demoed, a group of researchers at MIT have announced a working implementation of a hack that's been around in theory since 1998 but never implemented. Skirting around ol' Wernie Heisenberg and that Principle of his, the team exploited quantum entanglement to read the encryption keys encoded in photon polarizations from their momentums, avoiding detection by either end -- in other words, doing what was once thought impossible by cryptographers. The system isn't perfect, however -- in this early incarnation it can only nab 40% of transmitted data before giving itself away, and more importantly, it requires the invention of a "quantum non-demolition box" before the attacker can be anywhere but the same room as the receiver, since right now both attacker and receiver need to be using the same photon detector. Sounds like that might put a damper on that whole "undetectable" thing. Still, the researchers sound upbeat -- they're saying the work proves that no secret is truly safe. We're just wondering if they're pushing MIT to rename their department SETEC ASTRONOMY.
Negroponte suggests the OLPC can support Windows, may hit US schools
Just when you thought you knew everything there was to know about the OLPC, Negroponte, and the Sugar interface, in comes the man himself using the "W" word in an open-sourced conversation. Curiously enough, Nik Neg has not only stated that the present is "perhaps the most critical stage of the OLPC's life," but he also blurted out a quasi-firm $176 pricetag that would be attached to them. Additionally, he went so far as to admit that "XO's developers have been working with Microsoft so a version of Windows can run on the machines," and while no direct linkages were drawn to the recent $3 software package that the firm had announced, the writing is somewhat on the wall. Furthermore, a whopping 19 state governors have reportedly shown interest in grabbing a few of the inexpensive machines for their own schoolkids, and while the creator initially stated that the XOs were "designed for a totally different situation," he was also quoted as saying that business in the US "couldn't be ignored." C'mon guys and gals, how about a little less conversation and a little more action?Read - Hints of Windows on OLPCRead - US schools could adopt OLPC
MIT researchers tout "practical" holographic video
A team of researchers at MIT seem to think they've finally come up with a way to make holographic video a bit more practical for everyday use, touting the new system they've developed as a possible display for PCs and video game consoles, Technology Review reports. According to the researchers, the display will be small enough to fit in an entertainment center when finished, boast a resolution as good as a standard analog television, and only cost a "couple of hundred dollars." Much of that increased practicality comes from the fact that this latest version, dubbed the Mark III, simply relies on a standard graphics processor instead of specialized hardware. The researchers also managed to streamline some of the other optical hardware, which they say made the previous incarnations as big as a dining-room table. It apparently still has a few drawbacks, however, with it currently only able to display monochromatic holograms in a space about the size of a Rubik's Cube. They insist that's only a temporary problem though, and promise that the next model will be comparable in size to a desktop monitor and boast a full range of color. No word if there'll also be a port of everybody's favorite quasi-holographic arcade game, Time Traveler, to go along with it, but we can hope.
InsideOutside garb alerts you of uncomfortable areas
Sensor-laden clothing isn't exactly atypical this day in age, but the InsideOutside project takes wearable alerting to a new (albeit uncomfortable) platform. The garments are supposed to be rocked underneath of your corporately-approved suit and tie, and can purportedly assist you when coming in range of areas or situations that you don't spot right off, but you know would make you antsy if you did. Essentially, the garb "heats up or cools down uncomfortably" when the wearer gets near user-selected situations that they don't appreciate, meaning that you can program the clothing to tip you off when nearing CCTV farms, pop concerts, and rival fans of your alma mater. Sadly, we've no clue whether or not these sophisticated threads will ever make it to the retail scene, but if this thing (eventually) allows you to add spots to your discomfort list on-the-fly via your mobile, we're sensing a real winner.

MIT gurus developing bionic feet / ankles
Leave it to the brilliant minds at MIT's Biomechatronics Lab to crank out yet another bionic limb, as a newfangled mechanical foot / ankle combo is apparently on the minds of more than a few of its researchers. In a recent patent application, the team describes an "artificial foot and ankle joint" consisting of a "leaf spring foot member," flexible elastic ankle, and an actuator motor that applies force to the ankle. Aside from sporting a fairly intelligent system to improving one's gait, it also boasts a built-in safety feature that prevents foot rotation beyond a specified angle, and the internal sensors can also activate the motors at different intervals depending on the surface in which one is walking. The prosthetic feet join a horde of other bionic limbs and appendages meant to make life as an amputee a fair bit easier, and as terrific as this here invention sounds, we're betting the Olympic committee dashes your hopes of illegally obliterating a few running records by barring these from basic competitions.[Via NewScientistTech]
Samsung's SPH-M8100: another hi-spec MITs WiBro handheld
This isn't the first time we've seen Samsung's SPH-M8100. Remember, this is that crazy WiBro (mobile WiMax) phone sporting a dedicated RSS key (upper-right button on that Korean keypad). Only now, it's been slightly retooled for its official Korean launch. Besides the facelift, it appears unchanged spec-wise as a member of Sammy's elite MITs (Mobile Intelligent Terminal) family of devices. So it still packs the latest CDMA and EV-DO radios and DMB mobile television only now wrapped up in a pretty Windows Mobile 6.0 interface. Bluetooth, 2.8-inch display, and 2 megapixel camera still come standard. With any luck, we might see this rollout on Sprint's WiMAX network someday, somewhere. Yeah, right.
A123Systems crafts long-lasting automotive Li-ion for electric cars
A123Systems most certainly won't go down as the first startup to crank out what could be the batteries that reside in our future electric vehicles, but it seems to be edging ever closer to landing a full-blown contract with General Motors. GM has already selected the Massachusetts-based company to "develop batteries that might be used for the Saturn Vue," and it is pondering the idea of awarding the battery maker a similar deal for the Volt. The firm is garnering a good bit of praise for its "long-lasting, safe rechargeable Li-ions" that could potentially power the all-electric / hybrid vehicles of the future, but rather than relying on "cobalt oxide, it used iron phosphate assembled in a novel, nano-structure." Interestingly, the outfit's current offerings started out with the idea of utilizing self-assembling cells, but after they proved "intractably hard to develop," the idea was scraped in favor of the less pricey Li-ion approach. Still, don't expect these guys to run the table on automotive contracts, as there's already quite a few formidable opponents on the loose.
MIT brain bot mimics humans to recognize street scene
If imitation is the sincerest form of flattery, robots have been laying it on thick with human-inspired forms since day one. Unfortunately, AI hasn't quite kept up with mechanical achievements, mainly due to the fact that the human brain isn't merely mysterious in many regards, but dang complicated to boot. However, some brain experts at the Tomaso Poggio lab for brain research at MIT have made some impressive gains in bridging the gap. Using a computational model of how the brain processes info, the researchers created a bot capable of recognizing different objects in a street scene. The research is primarily targeted at brain geeks looking for ways to repair damaged brain functions and to better understand the brain's operation, but computer science should benefit from the biological inspiration of this research, and the methods used could lead to computer vision systems capable of better surveillance, car driving assistance, visual search engines and vision for robots. Because of its biological nature, the Poggio lab vision system is trained over time by being shown various street scenes, and the data in each picture is processed in much the same process as the brain goes through when presented with an image. Right now the system just mimics the brain's instant recognition faculties, but soon it'll be capable of putting more thought into what it sees -- for instance, cars do not belong in the sky -- so be warned people of earth: the first step in destroying an enemy is visually recognizing them. Our days are numbered.[Via Medgadget]
MIT gurus concoct Li-ion batteries that build themself
It's fairly reassuring that if those rollable, water-powered, paper, and ultracapacitor-based battery ideas don't exactly pan out, we've got yet another idea coming out of MIT that just might gain traction. Apparently, scientists at the university are working on self-assembling Li-ion cells when not thinking about what witty remark they'll plaster on their own spacecraft, and it seems that Yet-Ming Chiang and his colleagues have selected electrode and electrolyte materials that, when combined, "organize themselves into the structure of a working battery." By measuring various forces with "ultraprecise atomic-force microscope probes," the researchers were able to choose materials with just the right combination of attractive and repulsive forces, essentially creating a perfect environment for batteries that could build themselves. Additionally, a current prototype has displayed the ability to be discharged and recharged "multiple times," and while commercial uses aren't nailed down just yet, the backers are already envisioning how the technology could be used in minuscule devices where standard cells won't exactly fit in. Let's just hope this stuff doesn't cause too much friction whilst building itself up, eh?[Via TheRawFeed]
Plaster Georgia Tech / MIT's unmanned spacecraft with logos, text
If there's anything left to accomplish after creating autonomous UAVs and cramming optical circuitry on a silicon chip, it's allowing tax paying citizens to pen their thoughts on an unmanned spacecraft. In a joint initiative between Georgia Tech and MIT, the Your Name Into Space project aims to launch a small research satellite in 2010 into Earth's orbit, and the technology on board will purportedly "help pave the way for humankind to explore our solar system." Folks who throw their name, slogan, logo, or snarky catchphrases onto the craft can expect photographs of their adornment "with the Earth in the background" while it's orbiting space, and if your piece of textual glory lands on a segment that will be returning to Earth, it's all yours upon landing. So if you're looking to splurge a little this year on a bit of tax deductible fun, you can put nearly anything on this forthcoming machine for $35 to $250 per square centimeter, depending on location.[Via MAKE]
