MIT gurus use polyethylene to suck heat away from your next CPU

Man, MIT is making all of these other places of higher learning look silly. For what seems like the fortieth time this month, scientists at the university have revealed yet another breakthrough that might just change the way we compute in the future. Polyethylene, which is about as common a polymer as they come, could very well become a vital part of the way your next processor is cooled, as MIT boffins have figured out how to cause said polymer to “conduct heat very efficiently in just one direction, unlike metals, which conduct equally well in all directions.” If you’re still struggling to figure out why this matters, have a listen at this: “this may make the new material especially useful for applications where it is important to draw heat away from an object, such as a computer processor chip.” In fact, even Intel is taking notice of the development, though no one’s saying outright when exactly this stuff will leave the lab and hit Dell’s supply chain. There’s no time like the present, guys.

MIT Media Lab Extension: The New Home of Face-Melting Research [MIT Media Lab]

The renowned MIT Media Lab is a place where every project is an amazing, unbelievable glimpse into humanity’s technological future. Now, thanks to a massive $90 million extension, the architecture can match the wondrous excitement created within.

In case you haven’t had the opportunity to swing by this particular block in Cambridge, Massachusetts, here’s what the old Media Lab looks like. It’s still there. In fact, you can see the extension under construction, and marvel at the stark contrast in design.

Mensa Tetris

The six-level, interconnected extension, the work of the famed, award-winning architectural firm Fumihiko Maki and Associates, is like an immense Tetris puzzle. Every piece represents a functional element that is tightly connected to others, giving anyone inside the feeling of being inside a finished puzzle. Maki, himself the winner of a Pritzker Prize, was on hand over the weekend to officially open the MIT Media Lab. (It’s technically been in operation since December.)

As he described it, each piece of this six-level building connects to the next. Balcony offices overlook open air labs and work spaces. Colorful stairways bisect the central atrium, their red, blue and yellow coloring inspired by Piet Mondrian’s Composition with Yellow, Blue and Red.

Color aside, the trait hitting visitors in the face before they even walk through the door is glass. Cambridge building codes prevented a 100% glass exterior, so Maki came up with a loophole: bamboo. Inspired by translucent Japanese bamboo screens, Maki covered the remaining exterior with a mix of glass and aluminum tubes.

The result is at the same time beautiful and energy efficient, but also functional. We’re constantly reminded that this is one incredibly open, collaborative working environment.

From the street, especially at night, passers-by can literally see lab work happening within. Maki called this “filtered views,” inspired by the work of the pointillist artist George Seurat (lots of dots!). MIT played a part too, having provided Maki with an image of the Visible Man to further drive home the point that this lab space be open.

But enough architecture? What kind of world-changing stuff can we expect this multimillion dollar, 163,000-sq. ft. incubator to pump out in the future?

Well, if the past is any indication, plenty. The place that saw the beginnings of Guitar Hero, e-ink displays, OLPC and Lego Mindstorms is still driving much of the stuff that gets the Gizmodo editors, at least, sweating profusely in their blogging sweatpants.

The Media Lab will help “plumb the depths of how technology can have a greater impact on industry, society and business,” said Media Lab director Frank Moss.

To net denizens and geeks like you and me, that boils down to robotics, prosthetic limbs, AI and the obligatory Minority Report UI reference that any article mentioning 3D interfaces must include.

Fluid Media

As part of the opening, I was lucky enough to get a tour or some, but not all of the departments at the Media Lab. Departments like Biomechatronics, Cognitive Machines, Fluid Interfaces, Molecular Machines, Personal Robots, Smart Cities, Synthetic Neurobiology. It reads like Stephen Hawkings’ shopping list.

In any event, Fluid Media was one of the labs I got to tour first.

If you know Arduino, you’d be at home here, alongside the luminescent wallpaper, smart fabrics, “sewable computing” and inexpensive 3D fabricators that had me waxing nostalgic about Cory Doctorow’s Makers.

Above: No, not coasters or doilies. Sewable computers. If you aren’t wearing your mp3 player now, you will be soon.

Kindergarten Kids, Forever

The sense of play felt throughout the Media Lab’s open spaces owes itself to the students, of course, but it’s certainly assisted by the design. Moss called the atmosphere “serious fun,” in a building where bright minds “design by serendipity.” It’s pretty spot on. One lab leads into the other, encouraging social and professional interaction. Artists huddle with biomechanical engineers. Sometimes the union is short-lived, and sometimes it’s Guitar Hero.

But it’s serious fun: There’s a mission here, one that’s produced limbs for soldiers maimed in war; helped children learn robotics with crazy new Lego software; and created a paint brush, simply called I/O, that captures the essence of whatever you point it at—visual, musical or otherwise.

Even so, the fun, relaxed environment is apparent in this lab that director Moss says will change our futures. He and others, like Lifelong Kindergarten Department grad student Karen Brennan, were genuinely having fun while working with these high concepts and brain-bending experiments. The future, wild as it will be, looks pretty fun. Seriously.

MIT’s MeBot makes telerobotics fun again

We know how you feel. Sure, telerobotics has changed your life for the better, allowing to interact with people as if you’re really there, coasting through the halls of an institution of higher learning, dropping knowledge on anyone within shouting distance. But something’s missing. You aren’t happy, you aren’t free. MeBot, developed at MIT’s Personal Robotics Group and prepped for presentation at the Human-Robot Interaction conference in Osaka, Japan, looks to solve this. It adds movement to the equation, hoisting an OQO aloft for a head and adding in gesticulating arms to the equation. The idea is to allow the teleoperator to be more engaged through “head” and “arm” movements, with the arms being moved by handheld controls, and the head movement created by tracking the face of the operator. We could obviously conceive of a more elaborate representation, but the off the shelf components like the OQO brain seem worthy of commendation. Check out some video of the bot in action after the break.

MIT jumps straight to wirelessly powering multiple devices

Ah, wireless power. One of those mythical mysteries that are far more likely to remain “something to strive for” rather than “the next big thing.” Oh sure, we’ve got Palm’s Touchstone and the Powermat, but until we can hang a 50-inch plasma from our bedroom ceiling and power it up without a single wire, we’ll remain firmly unsatisfied. Thankfully for those of us in that camp, MIT exists, and a few of the school’s best and brightest are toiling around the clock in order to develop a technology that would power not one, but multiple devices sans cabling. Thanks to the wonders of coupling resonance, we’re told that the “overall power transfer efficiency of the wireless system could be increased by powering multiple devices simultaneously, rather than each device individually.” In theory, the system could be implemented by “embedding a large copper coil in the wall or ceiling of a room,” but there’s obviously no set time frame for release. We’ll be looking for you geeks at CES next year, okay?

Swarm of Micro-Helicopters Could Create a Giant 3-D Display

flyfire-3dfaces-small

Mechanical fireflies could help create a new kind of 3-D display, say researchers at MIT.

Standing in for the bioluminescent beetles will be LED-fitted, remotely controlled micro-helicopters that can be choreographed electronically to display shapes and images as they hover in midair. The project, called Flyfire, would use RC helicopters similar to the toys sold at the mall today.

“Each of the helicopters then acts as what we call a smart pixel,” E Roon Kang, the MIT research fellow who is leading the project, told Wired.com. “By controlling their movement, we can have the pixels flying through the air.”

The idea is almost all theoretical now since it is in its very early stages, says Kang. Researchers at MIT’s SENSEable City Lab and Aerospace Robotics and Embedded Systems (ARES) Lab are jointly developing the idea.

In traditional displays, pixels are static and arranged on a flat surface. Finding a way to make truly three-dimensional displays has been a frequent subject of research, but few practical solutions have emerged despite decades of effort.

The MIT researchers are betting that if each pixel can be made to hover in space and can be controlled reliably, they can create a giant 3-D display.

Ultimately the project would be a step in the direction of “smart dust” — the idea that computing devices will be extremely small, somewhat self-contained, and pervasive, says MIT.

The canvas made by little lighted helicopters can show either a two-dimensional image or a 3-D shape.

Currently researchers are trying to design these little helicopters that will serve as the smart pixels. Kang says the team is looking at microcopters with four rotors as a possible vehicle.

Simple as the idea may seem, creating an army of microcopters poses some significant technical challenges. For instance, each of these little devices will have be self-stabilizing. That means as they hover, they will have to maintain their co-ordinates with extreme accuracy for at least a few minutes.

Another problem lies in being able to reliably control thousands of these microcopters.

“Today we are able to simultaneously control a handful of micro-helicopters but with Flyfire, we are aiming to scale up and reach very large numbers,” says Emilio Frazzoli, head of the ARES Lab in a statement.

Flyfire is being conceived as a installation in a large public place, where the pixels can recharge every few minutes and then perform in space. So far, the team has performed simulations to show the idea at work and hopes to start designing the actual devices soon.

Check out MIT’s video explaining how the Flyfire idea will work.

MIT's Flyfire paints images in the sky using micro helicopters, is apparently top-secret

Micro helicopters, the kind that fit in the palm of your hand (and sometimes spread holiday cheer) are huge fun — and hugely frustrating. Have you ever tried to get one to hover in place next to another? Impossible! MIT thinks it can do that, not with just two but thousands of the little beggars all hovering in harmony as part of a project called Flyfire. By using LED-equipped drones the project pledges to build free-floating 3D displays, endowing them with enough smarts and positional awareness to organize themselves into an airborne canvas. It sounds deliciously exciting and challenging, yet for some reason the school has decided you aren’t to know about it, pulling its concept video and website offline. We can only imagine there’s a government agency involved here, possibly trying to stem the virulent spread of robo-socialism, but we invite you to leave your own conspiracy theories in comments.

Update: You can take your tinfoil hats off, the site and the video are both back online! We have the goods embedded after the break.

Germanium lasers offer ray of hope for optical computing

Bandwidth scarcity, is there any more pressing global issue that we’re faced with today? We think not. Given the exponential growth in both computing power and software’s exploitation and expectation of greater resources, it’s no surprise that at some point we’ll have to look beyond simple electrical currents as the transporters of our data. One bold step taken in that direction has been the demonstration of an operational germanium-on-silicon laser by researchers at MIT. By tweaking the electron count in germanium atoms with the help of some added phosphorous, they’ve been able to coax them into a photon-emitting state of being — something nobody thought possible with indirect bandgap semiconductors. Perhaps the best part of this is that germanium can be integrated relatively easily into current manufacturing processes, meaning that light-based internal communication within our computers is now at least a tiny bit closer to becoming a reality.

Germanium Laser Breakthrough Brings Optical Computing Closer

germanium-laser

Researchers at MIT have demonstrated the first laser that uses the element germanium.

The laser, which operates at room temperature, could prove to be an important step toward computer chips that move data using light instead of electricity, say the researchers.

“This is a very important breakthrough, one I would say that has the highest possible significance in the field,” says Eli Yablonovitch, a professor in the electrical engineering and computer science department of the University of California, Berkeley who was not involved in the research told Wired.com. “It will greatly reduce the cost of  communications and make for faster chips.”

Even as processors become more powerful, they’re running into a communications barrier: Just moving data between different parts of the chip takes too long. Also, higher bandwidth connections are needed to send data to memory. Traditional copper connections are becoming impractical because they consume too much power to transport data at the increasingly higher rates needed by next-generation chips. Copper also generates excessive heat, and that imposes other design limits because engineers need to find ways of dissipating the heat.

Transmitting data with lasers, which can concentrate light into a narrow, powerful beam, could be a cheaper and more power efficient alternative. The idea, known as photonic computing, has become one of the hottest areas of computer research.

“The laser is just totally new physics,” says Lionel Kimerling, an MIT professor whose Electronic Materials Research Group developed the germanium laser.

While lasers are attractive, the materials that are used in lasers currently — such as gallium arsenide — can be difficult to integrate into fabs.

That’s given birth to “external lasers,” says Yablonovitch. Lasers have to be constructed separately and grafted on to the chips, instead of directly building them on the same silicon that holds the chips’ circuits. This reduces the efficiency and increases the cost.

A germanium laser solves that problem, because it could in principle be built alongside the rest of the chip, using similar processes and in the same factory.

“It’s going to take a few years to learn how to integrate this type of laser into a standard silicon process,” says Yablonovitch. “But once we know that, we can have silicon communication chips that have internal lasers.”

Eventually, MIT researchers believe germanium lasers could be used not just for communications, but for the logic elements of the chips too — helping to build computers that perform calculations using light instead of electricity.

But University of California, Berkeley’s Yablonovitch says it is unlikely that light will replace electricity entirely. “I think we will be using light in conjunction with electronic logic circuits,” he says. “Light allows internal communications much more efficiently, but the logic elements themselves are likely to remain driven by electricity.”

The Cornucopia: MIT’s 3D food printer patiently awaits ‘the future’

The traditional fast food business model just never had a chance, now did it? Marcelo Coelho and Amit Zoran, a pair of whiz kids doing their thang over at MIT, have developed what very well may be the next major revolution in food preparation. It may also be the only machine that keeps you alive when the Robot Apocalypse goes down, but we’ll try to stuff that to the rear of our minds for now. Essentially, the Cornucopia concept is a 3D printer that precisely mixes foods and flavors from a number of canisters in order to produce something that’s edible (and supposedly close to what you ordered). Able to deliver “elaborate combinations of food,” the machine also has a rapid heating and cooling chamber that purportedly allows for “the creation of flavors and textures that would be completely unimaginable through other cooking techniques.” Color us skeptical, but we’re guessing these government-issued MREs probably taste just as good — guess we’ll find out for sure if the project ever gets its date with reality.

Ex-Seagate employee claims the company stole MIT research, tried to cover up its tracks

Sure, this ain’t the first time that Seagate’s allegedly run afoul of the law, but this tale will definitely have you breathlessly demanding more (you know, if patent infringement is exciting to you — which would actually be pretty weird). Way back in July 2000, Convolve (an M.I.T. spin-off formed to market the school’s hard drive noise reduction research) sued Seagate for using patented tech in its Sound Barrier Technology — with the end result being that Seagate drives no longer support automatic acoustic management. But that isn’t the exciting part. In a dramatic turn reported by The New York Times, a former Seagate employee named Paul A. Galloway has apparently provided “an eyewitness account” of what went down, including the theft of info obtained in a meeting between the two companies held in 1998 and 1999 and the destruction of blueprints relating to Convolve’s technology. As for the whistleblower, he claims that he was kept in the dark about the nature of the research he was working on, with Seagate even going so far as to take his computer with notes pertinent to the trial. All of this (and more) are detailed in an affidavit that is available (in PDF form) by hitting that source link — and, man, is it a page-turner!
