Paralyzed student uses robotic exoskeleton to walk at college graduation (video)
Austin Whitney hasn't been able to walk since a 2007 car crash left him paralyzed, but on Saturday the 22-year-old triumphantly strode across the stage to accept his degree from UC Berkeley. He had a little help, in the form of a specially crafted robotic exoskeleton developed by Berkeley engineering professor Homayoon Kazerooni. Kazerooni and his team designed the exoskeleton with lightness and affordability in mind, resisting the urge to load it up with expensive hardware and tethering the mechanized walker to a backpack that houses a computer and a rechargeable, eight-hour battery. As a result, the Austin walker won't enable the kind of acrobatic leaps that would make Lt. Rasczak proud, but its reduced mobility comes at a reduced cost of just $15,000. That's certainly not an impulse buy, though it's a welcomed alternative to other exoskeletons that retail for $100,000 or more. Walk past the break for a video of Whitney's momentous steps, along with a clip of Kazerooni describing his creation.
Ouch! Accident at Berkeley Apple Store construction site closes two businesses
Two walls have partially collapsed at the construction site for Apple's new Berkeley store, forcing two neighboring businesses to temporarily close. There was "A very large bang" at about 9:50 AM on the morning of February 22, according to George Kiskaddon, a partner at the book store Builders Booksource (located next door to the new Apple store). "One wall has been left leaning and bowing into the next door building," he said. Site workers were apparently digging new foundations on the site of the former Slater Marinoff building when two of the remaining free-standing walls suddenly sank about four feet into the ground. Fire officers evacuated the neighboring buildings as soon as they arrived as a precautionary measure. "There were no injuries," said Assistant Chief Sabina Imrie of the Berkely fire department, adding that the suspicion is that recent rain may have made the walls' foundations unstable.
Scientists grow nanolasers on silicon chips, prove microscopic blinkenlights are the future
What you see above may look like a nanoscale Obelisk of Light, ready to protect the tiny forces of Nod, but that's not it at all. It's a nanolaser, grown directly on a field of silicon by scientists at Berkeley. The idea is to rely on light to transmit data inside of computers, rather than physical connections, but until now finding a way to generate that light on a small enough scale to work inside circuitry without damaging it has been impossible. These indium gallium arsenide nanopillars could solve that, grown on and integrated within silicon without doing harm. Once embedded they emit light at a wavelength of 950nm, as shown in the video below. [Thanks, Paul]
World's first room-temperature semiconductor plasmon nanolaser created by Berkeley scientists
We're big proponents of the idea that everything is better with lasers, and a team of researchers at UC Berkeley has created a new type of semiconductor plasmon nanolaser, or spaser, that could eventually find a home in many of your favorite devices. The big breakthrough is that Berkeley's spaser operates at room temperature -- previous spasers could only sustain lasing at temperatures below -250° C -- enabling its use in commercial products. Plasmon lasers work by amplifying surface plasmons, which can be confined to a much smaller area than the light particles amplified by conventional lasers. This allows for extreme miniaturization of optical devices for ultra-high-resolution imaging, high sensitivity biological sensors, and optical circuits 100 times faster than the electronic variety. There's no word on how soon the technology will be commercially available, so you'll have to wait a bit longer for your first laser computer.
$1.7M Apple Store coming to Berkeley; residents sing with joy
The People's Republic of Berkeley is getting a new Apple Store. ifoAppleStore has all of the details and images of the 15 pound pack of Apple Store blueprints that were recently dropped off at the Berkeley, CA city planning department. The building permit application was filed on November 15th, and shows that the store will occupy and expand upon a current storefront. The Genius Bar is going to be huge, housing 17 seats where Apple-lovin' aging hippies can get assistance. Several local animal rescue and adoption agencies currently use a plaza in front of the location for animal "meet and adopt" get-togethers, but they'll soon need to find a new location as the storefront will obliterate the plaza. While the Milo Foundation and several other animal adoption groups might singing the blues over the loss of their plaza, at least one group of local residents listed on YouTube as the Art Licensing Group were so happy about the news that they recorded themselves singing a Christmas-themed tune welcoming the new Apple Store. Check it out after the break.
UC Berkeley researchers craft ultra-sensitive artificial skin, robots dream of holding eggs
Researchers and engineers have been toiling on synthetic skins for years now, but most of 'em have run into one major problem: the fact that organic materials are poor semiconductors. In other words, older skins have required high levels of power to operate, and those using inorganic materials have traditionally been too fragile for use on prosthetics. Thanks to a team of researchers at UC Berkeley, though, we're looking at a new "pressure-sensitive electronic material from semiconductor nanowires." The new 'e-skin' is supposedly the first material made out of inorganic single crystalline semiconductors, and at least in theory, it could be widely used in at least two applications. First off, robots could use this skin to accurately determine how much force should be applied (or not applied, as the case may be) to hold a given object. Secondly, this skin could give touch back to those with artificial hands and limbs, though that would first require "significant advances in the integration of electronic sensors with the human nervous system. Dollars to donuts this gets tested on the gridiron when UCLA and / or Stanford comes to town.
Laser backpack creates instant 3D maps, Venkman reminds you to not cross the streams (video)
Total protonic reversal? Small price to pay for an instantaneous 3D scan of a building's interior. That's what the backpack pictured above delivers, a project from UC Berkeley students and faculty Matthew Carlberg, Avideh Zakhor, John Kua, and George Chen. The pack contains a suite of laser scanners and positional sensors that enable it to capture images of building interiors as a fleshy assistant roams their halls. Those images can then be automatically pieced back together to create a 3D representation. We're having visions of instant Doom II WADs but the real boon here could be an extension to Google Maps where you could not only get a Street View but also an interior view. You know, really scope out that little Thai joint before you schlep yourself all the way downtown.
UC Berkeley researchers teach PR2 robot to fold towels
We've already seen Willow Garage's PR2 robot learn to roam offices in search of a power outlet, and it looks like some researchers at UC Berkeley have now helped it pull off its most impressive feat yet: folding towels. That may not sound like too hard a task, but it's actually proven to be quite a conundrum for robotic laundry researchers, since robots need to first pick up a towel from a pile and then somehow determine that this previously unseen shape is, in fact, a towel that can be folded. While it's still a long way from being the Roomba of laundry, the JR2 bot is now able to fold at the blistering speed of 25 minutes per towel, and the researchers are hopeful that the same computer vision-based approach can also be applied to a range of other tasks that have previously stumped robots. Head on past the break for the video -- don't worry, it's sped up.
Monkeys and scientists develop persistent "plug and play" control over brain-to-computer interface
While we've seen some pretty amazing things so far with computers jacked into human and monkey brains, systems so far have had to be re-learned each session by their subjects. In a new development, researchers at Berkeley have managed to get their monkeys to develop a "memory" for the controls, and recall them instantly each day. To do this, the scientists kept track of specific neurons from day to day -- a little tough to do, but obviously worth the hassle. It's good news for future brain-to-computer interfaces that will enable the disabled and the truly lazy to perform tasks and kick ass through the mere power of thought, but we're a little afraid of giving these monkeys too much in the way of internet access: the world doesn't need another 4chan.
CellScope, the cellphone microscope, gets UV upgrade to spot tiny glowing things
It was over a year ago that UC Berkeley introduced the world to CellScope, the 60x microscope for cellphones made from cheap, off the shelf components (like a re-purposed belt clip). Now, even though we're disappointingly still not seeing this thing in stores, there's an upgraded version able to take pictures of even smaller nasties. Using a filter the scope can now spot microscopic critters tagged with dye that glows under fluorescent light -- things like Mycobacterium tuberculosis (that's the cause of TB if you, like us, lack a med degree). A software app is able to then count the number of cells within a given sample and tell you whether to worry about that annoying cough. There's still no word on whether this product will ever actually start scoping out such things in the wild, but we certainly hope it will -- if only so that we can keep our vast collection of cellphone accessories complete.

Quest for invisibility cloaks revisited by two research groups
After a brief period of no news, it's time to revisit the world of invisible cloaks. Inspired by the ideas of theoretical physicist John Pendry at Imperial College, London, two separate groups of researchers from Cornell University and UC Berkeley claim to have prototyped their own cloaking devices. Both work essentially the same way: the object is hidden by mirrors that look entirely flat thanks to tiny silicon nanopillars that steer reflected light in such a way to create the illusion. It gets a bit technical, sure, but hopefully from at least one of these projects we'll get a video presentation that's sure to make us downright giddy.
Cyborg beetles commandeered for test flight, laser beams not (yet) included
Remember that DARPA initiative from a few years back to create cyborg insects? With funding from the agency, researchers at the University of California, Berkeley have managed to control a rhinoceros beetle via radio signals, demonstrated in a flight test shown on video at this week's IEEE MEMS 2009 conference. A module placed on the arthropod uses six electrodes affixed to the brain and muscles to commandeer its free will. The device weighs 1.3g -- much less than the 3g payload these guys can handle, and with enough wiggle room to attach sensors for surveillance. Ultimately, scientists say they want to use the beetle's own sensors -- namely, its eyes -- to capture intel and its own body energy to power the apparatus. Keep an eye on this one, we expect it to play a major role in the impending robots vs. humans war.[Thanks, Mimosa]
Researchers find ways to squeeze light into spaces never thought possible
It looks like a team of UC Berkeley researchers led by mechanical engineering professor Xiang Zhang (pictured) have found a way to squeeze light into tighter spaces than ever though possible, which they say could lead to breakthroughs in the fields of optical communications, miniature lasers, and optical computers. The key to this new technique, it seems, is the use of a "hybrid" optical fiber consisting of a very thin semiconductor wire placed close to a smooth sheet of silver, which effectively acts as a capacitor that traps the light waves in the gap between the wire and the metal sheet and lets it slip though spaces as tiny as 10 nanometers (or more than 100 times thinner than current optical fibers). That's apparently as opposed to previous attempts that relied on surface plasmonics, in which light binds to electrons and allows it to travel along the surface of metal, which only proved effective over short distances. While all of this is still in the theoretical stage, the researchers seem to think they're on to something big, with research associate Rupert Olten saying that this new development "means we can potentially do some things we have never done before.
Dual-display e-book concept mimicks reading, makes complete sense
It's no surprise that more displays is always better, but when it comes to mimicking the act of reading a book, dual displays is a clear step forward. Researchers at Maryland and Berkeley Universities developed a prototype dual-face, modular e-book reader that allows readers to fan pages to advance in a book or via trackball. If you're doing some serious research, the displays separate from one another, allowing one to display in landscape mode while the other runs in portrait. To complete the book meme, the device can be folded over to run in a more compact manner, and a simple flip changes the page. Possibilities for future e-book readers are endless here, so we applaud Maryland and Berkeley for using those research dollars.
Intel and Microsoft fund $20M grant to reinvent computing: where do you want to go tomorrow?
Although both Microsoft and Intel's R&D departments have been responsible for some nifty futuristic tech, the two companies got together last week and announced a $20M grant to two universities to "start over" and develop next-gen computing systems based around parallel processing. The grant will fund Universal Parallel Computing Research Centers at UC -Berkeley, which is kicking in another $7M, and the University of Illinois at Champaign / Urbana, which is donating $8M of its own. According to Mark Snir, head of the UIUC lab, the goal is to find a way to make "parallelism so easy to use that parallel programming becomes synonymous with programming" -- an increasingly important priority as current multi-core processors aren't necessarily being fully utilized, and 100-core processors aren't far off. That leads us to wonder: what to do with all that newly-unlocked processing power? Virtual-reality Facebook? Real-time visual augmentation? Finally being able to run Crysis? We know you've got ideas -- sound off in comments![Thanks, Luke]
Cellphone as microscope on the cheap, bugs beware
Go tech students! This handy idea, brought to you by the minds at University of California, Berkeley, brings up to a 60x microscope to your cell for roughly $75. The 60x attachment is useful for diagnosing things like Malaria while in the field, while its weaker 5x sibling can be used to look at skin conditions. The prototype was apparently made from off the shelf components -- including some low power LEDs that illuminate the subject -- and snaps in place with a modified belt clip. This is a pretty handy piece of kit when you consider how much easier it may be to snap a pic of something and fire it off to a lab via a data connection instead of having to physically bring a sample. We're sure the poor soul featured in the pic we have here agrees, as it looks like he / she may have a tiny shrimp infestation. [Via MAKE Blog]
Study finds no link between car accidents and yapping whilst driving
If you're ready for a healthy dose of unconventional wisdom, you've come to the right place, as a couple of confident graduate student economists at UC-Berkeley are purporting that there is "no match in the evening cellphone use spike and crash data." Basically, the duo is suggesting that although we've been on the mobile horn a lot more these days, the number of fatal vehicular accidents over the past 18 years have not experienced the same leap. Weird logic, we know, so take it for whatever it is (or isn't) worth.[Via Wired]
Berkeley's "respectful" surveillance cameras disregard faces
While blatantly spying on us is one thing, attempting to freshen it up by suggesting a venerating alternative is bordering on preposterous. As we've seen at the Sky Harbor airport, officials are trying nearly anything they can to make forthright invasions of privacy seem a bit less offensive, and a CCTV camera developed by researchers at the University of California, Berkeley is next up to bat. The so-called "respectful cameras" are aimed at places of employment, where specified workers would wear a given marker that could be recognized by the camera. After being identified, the camera would then spot out the face of the individual to provide some sort of false assurance that their identity is magically safe. The best, er, worse part, however, is that the system doesn't actually delete the face beneath the circle, as it "allows for the privacy oval to be removed from a given set of footage in the event of an investigation." So much for dodging Big Brother.[Via SciFiTech]
Online bird-watching game to debut; Blizzard fears mass exodus
Those nights of jubilation spent wasting time on City of Heroes, World of Warcraft, and Ultima Online just aren't what they used to be, but in just three days, the wait for the world's next incredible MMO will be over. Alright, so maybe online birdwatching won't take the globe by storm, but researchers at UC Berkeley and Texas A&M will be watching intently as the MMO goes live from the back porch of Craig Newmark. The Craigslist founder will be hosting a "remotely controllable robotic video camera" from the back deck of his San Francisco domicile, and interested users can log on to discover and classify wild birds in the Sutro Forest. By utilizing a "collaborative control interface," dozens of users can reportedly share the webcam simultaneously, which uses "highly responsive algorithms that automatically compute the optimal camera viewpoint." Gamers can rack up points by snapping shots of rare birds and then seeing just how many users can correctly classify it, so we'd highly recommend brushing up on your aves knowledge in preparation for April 23rd.[Via Physorg]
UC Berkeley on iTunes
Apple unleashed iTunes U to an unsuspecting world a few months ago with some success. You can now add UC Berkeley to the list of institutions that are using iTunes to deliver course podcasts to their students (and anyone else that visits itunes.berkeley.edu).Thanks, Ben.
