Subretinal implant uses light instead of batteries, shows promise in initial testing
There's been significant progress in bringing sight to the blind in recent years, and this looks set to continue that miraculous trend. Scientists at Stanford University have invented a subretinal photodiode implant for people who have lost their vision due to degenerative retinal diseases. Existing tech involves batteries and wires, but the new implant works without such crude appendages. Instead, it's activated by near-infrared beams projected by a camera that's mounted on glasses worn by the patient and can record what the patient sees. The beams then stimulate the optic nerve to allow light perception, motion detection and even basic shape awareness. It hasn't actually been tested with humans just yet, but the first few rodents volunteers have yet to lodge a single complaint.
Should Apple build a museum on the new campus?
Computer historian David Greelish argues in a blog post that Apple should build a museum on the grounds of its new Cupertino campus. He points out that the flying ring-shaped office will attract everyone from architects to Apple fans who want to check out the unique building. Apple, Greelish says, should embrace these tourists and build a museum that'll showcase Apple's achievements. Greelish offers his ideas on how the museum should be built and even provides a few sample designs. Greelish isn't the first one to propose an Apple museum. Apple toyed with the idea of a corporate museum in the past, but Steve Jobs rejected the idea and gave a collection of Apple memorabilia to Stanford University instead.
Stanford University and Apple: A beautiful relationship
Apple, Inc. and Stanford University go together like apple pie and ice cream -- they're outstanding on their own, but put them together and you have something very special. USA Today's Talking Tech reported on the close ties between Apple and Stanford in a posting and video last week. Many people are aware of the relationship between the university in Palo Alto and the company in Cupertino from the Walter Isaacson biography of Steve Jobs. In the book, Jobs is often taking long walks "in the hills above the Stanford University campus," he gave his famous 2005 commencement speech ("Stay hungry. Stay foolish.") at Stanford, and son Reed Jobs attends the university. But the largest connection between Stanford and Apple these days is in the way that many Stanford grads, students, and dropouts are making it rich as iOS developers. The university's entrepreneurial atmosphere has given birth to a gaggle of startups, many of which are well-known to iPad and iPhone users. Talking Tech's Jefferson Graham discusses Ankit Gupta, a Stanford student credited with helping create the highly successful Pulse News Reader. Ge Wang, the Stanford assistant professor who co-founded music app-maker Smule, has created virtual musical instrument apps for iPhone and iPad. He hired recent graduate Nick Kruge, who created the fun and unique MadPad app. Graham also highlights Matt Sullivan and Zach Weiner, creators of the Storytree app that is a finalist for the SXSW Interactive Awards tonight. Weiner, who is still a senior at Stanford, notes that developing apps and starting companies "is just really kind of emblazoned into the culture here," in reference to the university. Graham's interview of several past and present Stanford students who are making their name in the app world is embedded below.
WSJ: Safari loophole lets Google track Apple users through web ads
Stanford researcher Jonathan Mayer has discovered a curious Safari loophole that allows Google to track a user's browsing activity via cookie-laced web ads. As it turns out, Apple's browser normally accepts cookies from sites that a user visits, but automatically blocks them from third-party advertisers. As Mayer found out, though, advertisers can still circumvent this filter by enticing users to interact with ads in different ways. In the case of Google, the search giant embedded a "+1" button on ads produced with its DoubleClick technology, as part of an opt-in feature for Google+ users. If a user was logged in to Google+ and had agreed to see +1 ad displays, he or she would have a cookie planted on their device, thanks to a system that sent invisible forms from Apple computers or iPhones. This made it seem as if a user actually submitted the form intentionally, thereby convincing Safari to allow cookies. These cookies were only temporary, with shelf lives of up to 24 hours, but they could open the door for many more, since Safari allows sites to plant them after having received access to install at least one.After the Wall Street Journal notified Google of this loophole, the company promptly disabled it and duly apologized, adding that it didn't realize that its +1 system would plant tracking cookies on a user's device. "We didn't anticipate that this would happen, and we have now started removing these advertising cookies from Safari browsers," Google's Rachel Whetstone explained. "It's important to stress that, just as on other browsers, these advertising cookies do not collect personal information." An Apple spokesperson, meanwhile, issued the following statement: "We are aware that some third parties are circumventing Safari's privacy features and we are working to put a stop to it."
Nanoshells trap light for more efficient solar panels
Scientists at Stanford are hard at work trying to improve the efficiency and durability of solar panels -- two key factors that have kept the Sun from becoming a more popular source of energy. Their latest effort involves nanocrystalline-silicon, a material that has proven resilient and highly conductive, but not very good at absorbing light. Their solution, nanoshells -- hollowed out spheres of silicon that trap and recirculate light much like a whispering gallery does sound. Balls of the crystalline material are dipped in silicon, then hydrofluoric acid is used to eat way the center of the sphere, leaving a path for light to enter. The shells trap the light, allowing more of it to be absorbed, and also reduces the effect of non-optimal angles on energy production. Hit up the source for a few more details.

Marvell's Classroom 3.0 includes Armada-powered SMILE Plug Computer
All together now -- "Aww!" Marvell has just outed its Classroom 3.0 initiative here at CES 2012, with the star attraction being the cutie above. That's an Armada-powered plug computer known as SMILE, hailed as the "first plug development kit designed to turn a traditional classroom into a highly interactive learning environment." The device is capable of creating a "micro cloud" within a classroom, with the entire environment able to be controlled by the instructor. The hardware's being launched in tandem with an expanded One Laptop Per Child partnership, with the OLPX XO 3.0 trumpeted as the perfect companion product. It's capable of serving up to 60 clients at once, and it's based on Arch Linux for ARM; there's even a 5V Li-ion battery for back-up -- you know, in case that rambunctious kid of yours pulls the power. It'll be hitting kiddies and teachers alike this Spring, but there's nary a mention of price.
Stanford archives provide rare glimpse into Apple's early days as mere seedling (video)
Housed in a climate controlled storage facility operated by Stanford University, nearly 600 feet of shelf space is dedicated to preserve documents, videos and memorabilia of Apple and its early days as a young startup. The collection holds rare gems such as interviews with Steve Jobs and Steve Wozniak, both of whom discuss some of the rationale behind Apple's name -- Jobs asserts that it was selected to place his company ahead of Atari in the phone book. Originally intended to furnish Apple's corporate museum, the materials were donated to Stanford in 1997 after Steve Jobs' return to the company, which was most concerned with financial survival at the time. According to the university, more than 20 significant collections have been added to the archives in the subsequent years. The warehouse holds blueprints of the Apple I, user manuals, magazine ads, TV commercials and T-shirts, along with thousands of photographs that document Steve Jobs during his years as CEO of NeXT. Other rarities include a $5,000 loan document -- signed by the two Steve's and the partnership's third co-founder, Ron Wayne -- a spoof of Ghostbusters that starred former CEO John Sculley and other company leaders, who played "Blue Busters" to eliminate IBM, and handwritten sales entries of the very first Apple II's. While the location of the facility is undisclosed, we can only hope that, some day, the collection will be showcased for fanboys, fangirls and the public alike.

Researcher brings modified Touchpad into the MRI room, breakthrough ensues
Yes, the Touchpad is officially dead, but that hasn't stopped Stanford researcher Andrew B. Holbrook from using HP's tablet in a somewhat unexpected setting: the MRI lab. Holbrook, it turns out, has been developing a new, webOS-based system that could make it a lot easier for doctors to conduct interventional MRI procedures. Unlike its diagnostic counterpart, this brand of MRI can only operate within highly magnetic fields, thereby posing a threat to many electronic devices. Holbrook, however, may have found a way around this barrier, thanks to a modified Touchpad. With the help of HP engineers, the researcher stripped his tablet of metallic components, including its speakers and vibration motor, resulting in what the manufacturer calls a "minimally metallic device that could be used almost anywhere within the magnet room." With his Touchpad primed and loaded with apps for data manipulation, Holbrook went on to successfully integrate the device within an MRI system. He also developed a series of apps that allow technicians to monitor and manipulate an MRI procedure on their devices, regardless of whether they're in the magnet room itself, or outside. Holbrook says he's already started applying the same approach to webOS phones, in the hopes of providing doctors and researchers with an even more compact way to keep track of their patients. For more details on the system and future developments, check out the source link below. [Thanks, Mina]

Stanford program cracks text-based CAPTCHAs, shelters the replicants among us
CAPTCHAs. In the absence of a Voigt-Kampff apparatus, they're what separate the humans from the only-posing-to-be-human. And now three Stanford researchers have further blurred that line with Decaptcha, a program that uses image processing, segmentation and a spell-checker to defeat text-based CAPTCHAs. Elie Bursztien, Matthieu Martin and John Mitchell pitted Decaptcha against a number of sites: it passed 66% of the challenges on Visa's Authorize.net and 70% at Blizzard Entertainment. At the high end, the program beat 93% of MegaUpload's tests; at other end, it only bested 2% of those from Skyrock. Of the 15 sites tried, only two completely repelled Decaptcha's onslaught -- Google and reCaptcha. So what did the researchers learn from this? Randomization makes for better security; random lengths and character sizes tended to thwart Decaptcha, as did waving text. How long that will remain true is anyone's guess, as presumably SkyNet is working on a CAPTCHA-killer of its own.
Stanford builds super-stretchy skin sensor out of carbon nanotubes (video)
An artificial skin that senses pressure, pinches and touch sounds like a macguffin from The Outer Limits (the episode "Valerie 23" if we recall correctly), but that's what a team from Stanford University has cooked up on the back of its pick-up truck. Sensors made of silicon films with a matrix of liquid carbon nanotubes ensure the material snaps back to its original shape no matter how frequently it's pulled about. When compressed, the electrical conductivity of the skin changes, and by measuring where and by how much, it knows the location and pressure of where you jab your fingers. The team wants to combine this super stretchy film with a much more sensitive sensor and if it can do it, then the technology could end up as an artificial skin for burn victims, covering prosthetic limbs or even replacing your multitouch display -- just be careful, you might hurt Siri if you pinch-to-zoom her too hard.
Student spends summer turning a tablet into a Braille writer, says mowing lawns is for chumps
Lots of us spend the summer by the pool, sipping Mai Tais and working on our tans, but Adam Duran had better things to do with his vacation. Instead of engaging in such lethargy, Duran attended the Army High Performance Computing Research Center's summer course held at Stanford, where he and his mentors, Sohan Dharmaraja and Adrian Lew, developed a Braille writer app for tablets. You see, the average 8-key Braille writer is a custom laptop that costs $6,000, so given the paltry pricing on today's slates, this new solution is considerably more economical. Users place their fingertips on the display and the app populates keys underneath them, rendering tactile indicators of the keys' location unnecessary. Plus, the virtual keyboard provides a custom fit for your phalanges no matter how big or small they may be. The project has some "technical and legal hurdles to address" before it's made available to the masses, but here's hoping they can clear them soon. Video of the app in action after the break.
Dipping capacitors and batteries in nanotubes could improve capacity
Stanford researchers figured out that, by dipping electrodes for super capacitors in a solution of carbon nanotubes or a conductive polymer they could increase the charging capacity by up to 45-percent. The team started working with composite electrodes of graphene and manganese oxide, since manganese is cheap and plentiful, but were hamstrung by its low conductivity. The thin coating of more conductive material greatly boosted the capacitance of the electrodes, and thus their ability to hold a charge. Further tests are still required to find the actual energy density of the dipped electrodes, but lead researchers Yi Cui and Zhenan Bao are already working on a way to apply the same technique to batteries.
Google Fiber beta test goes live, bathes Stanford in high-speed regularity
When we last checked in on the Google Fiber project, engineers were busy laying the groundwork for a 1Gbps network across both Kansas Cities, while preparing to launch a beta test near Stanford. Now, it looks like the beta service has gone live in the Palo Alto area, according to a lucky Reddit user who claims to be using it. The ISP is available free of charge to students and faculty members within the area, at pretty mouth-watering speeds. No word yet on when the Kansas City communities will receive similar treatment, but you can gaze in awe at the Stanford Speedtest result, after the break.
Stanford schooling unwashed masses with free online Intro to Artificial Intelligence (video)
If you fancy yourself a Stanford (wo)man, but lack the requisite dollars to actually attend, now's your chance to collect those collegiate bragging rights. Starting October 10th, you can join Professor Sebastian Thrun and Google's Director of Research, Peter Norvig, in a free, online version of the school's Introduction to Artificial Intelligence course. The class covers, "knowledge representation, inference, machine learning, planning and game playing, information retrieval, and computer vision and robotics," and ambitiously aims to be the largest online AI course ever taught. If you're feeling the ole red and white, you can register at the source link below, but if you're looking for the official Stanford stamp of approval, we're afraid you're barking up the wrong tree -- non-students will receive a certificate of completion from the instructors only. Still interested? Check out the video introduction after the break and hit the source for more details.
Ukranian Defense Chief seemingly plagiarizes Steve Jobs' graduation speech
Raisa Bogatyrev, the Ukrainian Secretary of National Security and Defense, is causing a stir with her recent graduation speech at Kiev-Mohyla Academy. According to transcripts, her speech was eerily similar to a commencement address delivered by Steve Jobs to the 2005 graduating class at Stanford University. Jobs' candid speech focuses on pursuing your dreams despite setbacks in life, including illnesses that bring you face-to-face with death. According to the Ukrainian sources, some of Jobs' most memorable quotes from his speech were echoed by Bogatyrev in her address. The National Security Council responded to this accusation by pointing the finger at Bogatyrev who is the one responsible for the content of the speech. They claim she did not lift the speech but is inspired by a variety of sources, one of which may be Steve Jobs.
Report: data centers accounted for just 1 to 1.5 percent of electricity use last year, Google claims less than 1 percent of that
You'd think, watching companies like Apple break ground on sprawling data centers, that the number of servers powering our untethered lives was on the rise. In a different decade, you might have been right. But not this one. According to a study prepared at the request of The New York Times, the number of servers in use has declined "significantly" since 2005. That's mostly because of the financial crisis of 2008, says lead researcher Jonathan G. Koomey of Stanford University, but we also can't discount the effect of more efficient technologies. What's more, he says, servers worldwide consume less energy than you might have guessed: they accounted for somewhere between 1 and 1.5 percent of global electricity use in 2010. And while Google, the king of cloud computing, has been cagey about revealing just how many servers house its treasure trove of data, the company said that of that 1 to 1.5 percent, it accounted for less than 1 percent -- meaning, just a hundredth of a percent of all the electricity consumed last year. All told, data centers' energy consumption has risen 56 percent since 2005 -- a far cry from the EPAs 2007 prediction that this figure would double by 2010, with annual costs ballooning to $7.4 billion. Then again, this slower-than-expected growth could well be temporary. Though Koomey can't specify to what extent the financial crisis and technological advancements are to blame, he insists, broadly speaking, that we're primarily seeing fallout from the economic slowdown -- a stay of execution, of sorts, for those of us rooting for energy conservation.
Stanford researchers create transparent battery, dream of a see-through iPhone (video)
We've had about all of the transparent displays we can handle. Besides, what good is a screen you can see through if the electronics behind it are as opaque as ever? Thankfully, the fine folks at Stanford are working hard to move us towards a future filled with invisible gadgets. Yi Cui and Yuan Yang led a team that have created a lithium-ion battery that appears transparent. In actuality, the cells are composed of a very fine mesh of electrodes, approximately 35-microns wide, that are small enough to appear invisible to the naked eye. The resulting power packs are cheap and flexible but, currently, can only store about half as much energy as a traditional Li-ion battery. Cui has a particular destination in mind for creation, as he told the college paper, "I want to talk to Steve Jobs about this. I want a transparent iPhone!" Check out the video after the break.
