Here's how doctors will test Apple's new patient tracking features
Apple briefly hinted last week that hospitals would soon try out HealthKit's patient tracking technology, and we now know how those experiments are going to work. According to Reuters, both Duke University and Stanford University are weeks away from launching trial programs that will let doctors monitor vital stats with patients' permission. In the Stanford test, young Type 1 diabetes sufferers will carry both an iPod touch and a smart glucose meter to keep tabs on their blood sugar levels. There are fewer details surrounding Duke's pilot, but it will track the blood pressure and weight of those with cancer or heart disease.
Stanford turns to Twitter to track earthquakes
It's easy to tell when an earthquake hits an area full of Twitter users -- there's frequently a rush of panicked tweets within seconds of the ground shaking. If Twitter and Stanford University have their way, though, those posts could be useful for more than just alerting friends. They've conducted research showing that geotagged tweets can help model the effects of a quake while it's happening. When you combine geological data with the volume of related tweets within a given radius, it's easier to determine the intensity of tremors and accurately track how they spread.
This skin-sensitive controller ramps up game difficulty when you're bored
The concept of using your emotional state to alter gameplay is nothing new, but the technology to make that happen has frequently relied on cameras and other special add-ons. Stanford University's Corey McCall has a far more elegant solution -- he recently developed technology that builds skin-based emotion detection into an otherwise ordinary gamepad. The controller changes the intensity of a game based on the feelings you convey through breathing, heart rate and motion. It can boost the difficulty level if you're obviously bored, or tone things down if you're taking a challenge way too seriously. There may not be a great need for McCall's approach when systems like the Xbox One can check your pulse at a glance, but it could let console and peripheral makers offer emotion-aware gaming without requiring cumbersome (or costly) extras.
Art Levinson discusses the post-Jobs era
Art Levinson summed up his experience as chairman of Apple's board of directors since Steve Jobs passed in one word. "Weird," said Levinson who spoke on Tuesday at Stanford's Graduate School of Business "I'm still not to the point where I walk into that boardroom and don't miss Steve," Levinson added. According to a report in Fortune, Levinson talked about a wide range of topics covering his relationship with Jobs, his role as the chairman of Apple's board and his management style at Genentech. Though there are changes at Apple under Tim Cook, Levinson is optimistic about the company in the long run. "There [are] long-term signs of how a company is doing and whether or not Apple sells 47 or 48 million iPhones -- let somebody else worry about that," he said. You can read more about Levinson's talk in the article on Fortune and view people's reactions on Twitter. [Image from Sten Tamkivi]
Stanford researchers create 'world's first' all-carbon solar cell, do it on the cheap
Harnessing the awesome power of the Sun isn't just dependent on the efficiency of solar cells, but also on making them affordable. Current techniques aren't exactly cheap, but researchers from Stanford University think they've made a bit of a breakthrough by producing a relatively inexpensive photovoltaic cell using nothing but carbon. We're sure other scientists might disagree with the 'world's first' claim, but those at Stanford think it's a matter of language, and that these other pretenders are "referring to just the active layer in the middle, not the electrodes." The team selected a trio of carbon types to use in their cell: a mixture of nanotubes and buckyballs make up the light-absorbing layer, while graphene is being utilized for the electrodes. The carbon amalgam can be applied from solution using simple methods, meaning the flexible cells could be used to coat surfaces, although you won't be seeing it smeared over anything too soon. The prototype only touts a "laboratory efficiency of less than 1 percent," so it can't compete with traditional solar cells just yet. Also, it only absorbs a sliver of the light spectrum, but the researchers are looking to other forms of the wonder element which could increase that range. They are hoping that improving the structure of the cells will help to boost their efficiency, too. They might never generate the most energy, but the all-carbon cells can remain stable under extreme conditions, meaning they could find their calling in harsh environments where brawn is a little more important than status, or looks.
Folding@Home packs up on PlayStation 3: over 100 million computation hours added to research
Squared away in the PlayStation 3's latest software update post, Sony announced that the Folding@Home service will be retired starting next month, alongside the console's 4.30 update. The project, which tied into Stanford University's work on protein folding and research into the causes of a diseases like Alzheimer's, pulled in over 15 million PlayStation owners since it started in 2007. In fact, according to Stanford's client statistics, PS3 users offered the second greatest contribution after Windows devices, adding more than 100 million computation hours to the research project -- and well, we did our bit.
Google releases Course Builder, takes online learning down an open-source road
Google is well-known for projects with unexpected origins. It's almost natural, then, that the code Google used to build a web course has led to a full-fledged tool for online education. The open-source Course Builder project lets anyone make their own learning resources, complete with scheduled activities and lessons, if they've got some skill with HTML and JavaScript. There's also an avenue for live teaching or office hours: the obligatory Google+ tie-in lets educators announce Hangouts on Air sessions. Code is available immediately, although you won't need to be grading virtual papers to see the benefit. A handful of schools that include Stanford, UC San Diego and Indiana University are at least exploring the use of Course Builder in their own initiatives, which could lead to more elegant internet learning -- if also fewer excuses for slacking.
Autonomous Wave Glider bot launched to track sharks, beam real-time data to your iPhone and iPad
When they're not breaking world records, fuel-hating Wave Glider seabots like to indulge in other hobbies, like shark tracking. One of the vessels has just been launched off the coast near San Francisco (vid after the break), adding a mobile worker to the existing local network of buoy-mounted receivers. They monitor the movements of electronically tagged sea life, including the fearsome Great White, picking up signals within a 1,000-foot range while researchers from Stanford University analyze the data from the safety of the shore. Better still, the free Shark Net iOS app gives anyone the chance to track these things, and activity should increase as the monitoring network (hopefully) expands along the west coast and more bots are introduced. You didn't think the world's fascination sharks was limited to only a single single week, did you?
Diamond hones DOE X-ray laser howitzer to razor-sharp precision
The US Department of Energy's SLAC accelerator lab already has a pretty useful X-ray laser -- the Linac Coherent Light Source (LCLS). But, recent modifications to the device have scientists drooling over its new found potential. Using a thin wafer of diamond, the Stanford-run lab filtered the beam to a lone frequency, then amplified it in a process called "self-seeding." That's given the world's most powerful X-ray laser even more punch by tossing out unneeded wavelengths which were reducing its intensity. The tweaks allow scientists across many fields to finesse and image matter at the atomic level, giving them more power to study and change it. According to the lab, researchers who came to observe the experiment from other X-ray laser facilities "were grinning from ear to ear" at the possibility of integrating the tech into their own labs. The SLAC team claims they could still add 10 times more punch to the LCLS with further optimization, putting the laser in a class by itself -- X-ray-wise, anyway.
Scientists create first computer simulation of a complete organism
Everyone, meet Mycoplasma genitalium, the subject of many scientific papers, even more vists to the clinic and now the first organism to be entirely recreated in binary. Computer models are often used for simplicity, or when studying the real thing just ain't viable, but most look at an isolated process. Stanford researchers wanted to break with tradition and selected one of the simplest organisms around, M. genitalium, to be their test subject. They collated data from over 900 publications to account for everything going on inside the bacterial cell. But it wasn't just a case of running a model of each cellular process. They had to account for all the interactions that go on -- basically, a hell of a lot of math. The team managed to recreate cell division using the model, although a single pass took almost 10 hours with MATLAB software running on a 128-core Linux cluster. The representation was so accurate it predicted what M. genitalium looks like, just from the genetic data. And, despite the raft of research already conducted on the bacterium, the model revealed previously undiscovered inconsistencies in individual cell cycles. Such simulations could be used in the future to better understand the complicated biology of diseases like cancer and Alzheimer's. Looks like we're going to need more cores in that cluster. If you'd like to hear Stanford researcher Markus Covert's view on the work, we've embedded some footage beyond the fold.
Sally Ride, first American woman in space, dies at 61 (updated)
It's a sad day for space travel. Sally Ride, the first American woman to ever travel to space, has died at the age of 61 after a bout with pancreatic cancer. She's best known for breaking NASA's gender barrier by flying on Space Shuttle Challenger on June 18th, 1983, but she spent much more of her time guiding our future in space while here on Earth -- she founded NASA's Office of Exploration and directed its early strategy, and she later went on to lead the California Space Institute as well as teach physics at the University of California in San Diego. Her final decade saw her establish Sally Ride Science to encourage students wanting to follow in her footsteps, especially girls. Ride blazed one of the brighter trails in technology, and she'll be missed. Update: Ride is survived by her same-sex partner of 27 years, Dr. Tam O'Shaughnessy. [Image credit: National Archives]
Ubiquitous nanotubes could reboot Edison-era nickel-iron battery technology
Back in the 1920s, Thomas Edison's dream of an electric automobile was ultimately foiled by those meddling petroleum engines. But thanks to nanotube research from Stanford University, one legacy from that era may regain some glory: nickel-iron batteries. It turns out that carbon nanotubes doped with nickel and iron crystals can top up the normally slow-charging cells in a matter of minutes -- according to the scientists, that's almost 1,000 times faster than in the past. Although the batteries couldn't power your Volt or Prius due to a lack of energy density, they could give an extra jolt to their lithium-ion siblings for quicker starts and regenerative braking. The researchers are working on improving stability to allow more charging cycles, but it might be an extra in-your-face for Edison if it pans out.
Explicit consent becomes mandatory with latest 'do not track' proposal, backs Microsoft into the corner
Remember how Microsoft said it'd enable the "do not track" feature by default for all users of Internet Explorer 10? Well, it's not likely to happen -- at least from the looks of things. The move caused more than an uproar in the advertising industry, which had agreed to abide by these preferences only if users could, indeed, choose for themselves. With Microsoft's bullish decision to go forward and make this setting default, advertisers argued they'd be left with no choice but to bust the deal wide open and ignore these preferences. In attempt to make sure the whole "do not track" effort isn't derailed, the latest compromise proposal -- authored by the EFF, Mozilla and Jonathan Mayer of Stanford University -- now includes a specific provision that requires users to provide explicit consent before any tracking preferences can be transmitted. The same document acknowledges that the proposal has yet to be extensively discussed with stakeholders, but from the looks of things, "do not track" by default seems headed for a quick death. It's too bad we didn't have the time to get better acquainted with Microsoft's heavy lash against advertisers, but we've a feeling that you can decide this one for yourselves, right?

Scientists develop rewritable digital storage built into DNA; biological binary exists
We've seen DNA flirt with computing and storage before, but a biological system that can record digital data? That's something different. Stanford researchers used natural enzymes to create rewritable data storage built directly into living cells' DNA. The enzymes can flip DNA sequences back and forth, enabling a programmable, binary-like system where the DNA section is a zero if it points in a particular direction and a one if it points the other way. (Color coding indicates which way a section of genetic code is facing.) The so-called recombinase addressable data (RAD) module can store one bit of information without consuming any power, and in addition to letting scientists switch DNA sequences, it allows them to count how many times a given cell has doubled. That capability could come in handy for studying how cancer spreads, and could even give scientists the ability to "turn off" affected cells. The next step for the scientists will be upping the storage capacity to a byte, which will reportedly take a good ten years. That gives you plenty of time to study up on that science -- for a start, check out a more detailed account of the research in the source link.
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.
Ferrari president reportedly meets with Tim Cook
Speaking at Stanford University's View From the Top lecture series, Ferrari President and Chairman Luca di Montezemolo talked about a recent meeting he had with Apple CEO Tim Cook. When talking to the Stanford students, di Montezemolo had many good things to say about Apple, according to a Wired report. di Montezemolo said he saw many similarities between his role at Ferrari and Jobs's role at Apple - both men took ailing companies and brought them back to life. He praised Apple for its inspiring management and leadership style, and admired the company's focus on simplicity, design and "a passion for product."
Another reason to buy gold: nanoparticles help to kill brain tumors
Stanford scientists have used lab-made gold nanoparticles to highlight malignant tissue in the brain, making it easier for surgeons to cut out tumors while leaving healthy bits in tact. Measuring just five millionths of an inch in diameter, these tiny glistening orbs are injected into the patient and then left to bleed out through leaky blood vessels in parts of the brain that have been damaged by the disease. They then get stuck in the bad tissue itself, marking it out for the scalpel when viewed with the right type of imaging. It's not totally new -- we've actually seen gold nanotech deployed against the Big C in stem cells before, but better to be useful than avant-garde. [Brain image via Shutterstock]
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.
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.
