New fuel cell keeps on going even once the fuel's dried up
Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell -- developed at Harvard's School of Engineering and Applied Sciences -- that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both generate and store power. Example applications would be situations where a lightweight power source is required, with the potential to provide reserve juice should the main fuel source run out. The team who developed the cell usually work with platinum-based SOFCs, but they can't store a charge for much more than 15 seconds. By adding the VOx, this proof of concept extended that by 14 times, with the potential for more lifespan with further development. Especially handy if you're always running out of sugar.
Outspoken Harvard professor Jonathan Zittrain to head FCC's open internet advisory panel
The FCC has created a new forum for corporations, experts and activists to scrap over web laws: The Net Neutrality Advisory Committee. Members have been tasked with "tracking and evaluating the effects of the FCC's Open Internet rules," as well as making policy recommendations. The new group is to be led by Harvard professor and long-time defender of an open internet, Jonathan Zittrain, whose appointment echoes that of Tim Wu -- another expert in a senior advisory position over at the FTC. Harvard University is no stranger to what can go wrong when open access is stifled, so perhaps the good professor can shake things up a bit.
Mind-operated robot arm helps paralyzed woman have her cup o' joe (video)
Researchers at the Braingate2 consortium have made a breakthrough that allows people with spinal cord or stroke injuries to control robotic limbs with their minds. The original project allowed subjects with motor cortex-implanted chips to move cursors on a screen with their minds, but they can now command DEKA and DLR mechanical arms to grasp foam balls and sip coffee. Researchers noted that dropped objects and missed drinks were frequent, but improved brain sensors and more practice by subjects should help. To see the power of the mind move perhaps not mountains, but good ol' java, jump to the video below.
MIT and Harvard announce edX web education platform, make online learning cheap and easy
We'll forgive you if you failed to take MIT up on its offer take its courses for free when it rolled out its MITx online learning platform last year. However, Harvard took notice of its efforts, and has joined MIT online to form the edX platform and offer courses and content for free on the web. There's no word on the available subjects just yet, but video lessons, quizzes and online labs will all be a part of the curriculum, and those who comprehend the coursework can get a certificate of mastery upon completion. edX won't just benefit those who log on, either, as it'll be used to research how students learn and how technology can be used to improve teaching in both virtual and brick and mortar classrooms. The cost for this altruistic educational venture? 60 million dollars, with each party ponying up half. The first courses will be announced this summer, and classes are slated to start this fall.

Harvard tired of overpaying for research, tells faculty to open up
The grand dame of Ivy League schools is taking action against one of higher learning's pet peeves: the exorbitant price of research journals. Even though the e-reader revolution may have already touched other schoolbooks, so far academic subscription prices -- with some journals as high as $40,000 -- are becoming unsustainable, according to Harvard. To that end, it's taking the lead and pushing its own faculty toward open access publishing, and encouraging them to quit boards of journals that aren't. That could in turn prod other schools to take the same steps, and allow Harvard to focus on more, ahem, interesting pursuits.
Aluminum oxide 'egg-carton' could improve quantum dot efficiency
Quantum dots have been deemed the future of everything from light bulbs, to displays and solar panels. Yet, one thing has been keeping them down -- a lack of efficiency. Current has a tendency to leak in between the dots, instead of passing straight through all the time. But, researchers at Harvard have found a possible solution. By surrounding the dots with an insulating layer of aluminum oxide, which hugs them like an egg carton, they were able to direct the current, greatly increasing the light-emission yield and reducing wasted electricity. Of course, this only applies to light-producing quantum dots at the moment, but it's possible it could eventually be applied to solar panels and increase the amount of energy harvested from the sun's rays.

Harvard-designed 'soft robot' shows you how low it can go (video)
It's the stuff of slow-moving robopocalyptic nightmares: a 'soft robot' designed by a team of Harvard scientists that draws inspiration from invertebrates like worms and starfish. The wired 'bot is made from a flexible elastomer material that allows it to squeeze into spaces that are inaccessible for more traditional robots. Inside are chambers that inflate and deflate, allowing the thing to undulate forward. Definitely check out the robot in action after the break.
IBM's Watson takes Harvard, MIT business students to school, drops the mic
There was a massacre in Boston the other night, and Watson had blood all over his hands. The IBM supercomputer and undisputed Jeopardy champ made a virtual appearance in Beantown this week, ostensibly as part of a symposium on the ways in which advanced analytics could reshape business. In reality, though, he only showed up to remind everyone that he's really smart. During the event, Watson squared off in a Jeopardy scrimmage against two groups of students from some of the most prestigious business schools in the world -- Harvard Business School, and MIT's Sloan School of Management. The brainiac b-schoolers (including two former Jeopardy contestants) did remarkably well for the first two rounds; Harvard managed to get within $1,800 of the machine going into Final Jeopardy, and even held the lead at one point, following a gutsy Daily Double (MIT didn't fare so well, but hey, we're all human, right?). The wheels came off, however, once the battle entered Act III, when Watson pulled away for the win. Both the computer and Team Harvard answered the final question correctly, but Watson wisely bet just enough to keep the Ivy Leaguers at bay. When the smoke cleared, Watson was left standing with $53,601, Harvard finished with $42,399 and MIT came in a distant third, with $100. Adding insult to injury is the fact that Watson wasn't even in the same building as his muggle competitors -- nor, for that matter, was he in the same state. IBM kept all of the machine's processors and memory chips at its Research Center in Yorktown Heights, New York. Watson had already come up with answers to the questions prior to this week's showdown, but placed wages, chose categories and buzzed in responses in real-time. According to IBM, Watson's presence wouldn't have changed the outcome of the game, which was followed by a discussion on the effects that similar technologies could have on the financial world. The most immediate impact? Bruised egos. Re-live the event at IBM's liveblog below, or find more information in the PR after the break.
Robot dragon teaches kids language skills, battles impulse to terrorize city
Did you have trouble learning language skills at a young age? It's probably because you didn't have the right teacher. And by "the right teacher," we mean the right robotic dragon, naturally. This cuddly little mythical beast is the joint creation of researchers at Northeastern University, MIT and Harvard -- some of whom were behind the decidedly creepier Nexi bot. It's part of a National Science Foundation-funded program to help young children learn language skills, suggesting that forming a bond with a teacher plays an important role in the educational process. The dragon will be brought to preschool classes to help test out this hypothesis. Hopefully a robotic knight will also be on-hand, just in case.
Harvard's Kilobot project does swarm robots on the cheap (video)
We've certainly seen plenty of swarm robots before, but few of those are cheap enough to let you easily build something that can truly be called a "swarm." These so-called Kilobots developed by Harvard's Self-organizing Systems Research Group, however, can apparently built for just $14 apiece, and can each be assembled in just five minutes to boot. Despite that low cost, the bots are still capable of plenty of swarm-like behaviors, including the ability to follow the leader, disperse in an environment, put on a synchronized LED light show. Head on past the break for a pair of videos.

Using an iPhone app to test for landmines
One of the big problems with using metal detectors to find unexploded landmines is that they detect all pieces of metal in the ground, often forcing operators to inspect every suspect item they find. This can be very dangerous, so researchers at Harvard have figured out how to use smartphones to find landmines. Trained and experienced operators can tell by the beeps coming from their detectors the size and shape of objects found. Harvard researchers take these beeps and map them onto a smartphone screen, such as an iPhone, to better visualise what's been found. The PETALS (Pattern Enhancement Tool for Assisting Landmine Sensing) researchers have shown that inexperienced users are up to 80 percent more efficient using their technique, which could save a lot of lives. Using existing devices like iPhones makes the system potentially very cheap to deploy. Researchers hope that users already familiar with their smartphone interface should find it simple to use.
Metal detectors and smartphones make beautiful, mine-sniffing music together
Harvard researchers have married a smartphone to a metal detector to create PETALS, a low cost way to improve mine detection in third-world countries. Traditionally, locating land mines has required a carefully trained ear to distinguish deadly explosives from, say, a can. This new system removes some of the guesswork by mapping the beeps on a cell phone screen, creating a silhouette of whatever is beneath the surface. Similar results have been accomplished using acoustic sensors, but so far they've been relegated to research projects and would likely be too expensive for use where they're needed most. Not only should the simplicity of PETALS (which stands for Pattern Enhancement Tool for Assisting Land mine Sensing) make it cheap and easy to deploy but, in tests novice de-miners were able to improve their performance by 80 percent -- that's a least a few less brave humanitarians going "boom" in the field.
Carbon nanotubes used to more easily detect cancer cells, HIV
Cancer's not slowing its march to ruining as many lives as it possibly can, so it's always pleasing to hear of any new developments that act as hurdles. The latest in the world of disease-prevention comes from Harvard University, where researches have created a dime-sized carbon nanotube forest (read: lots of nanotubes, like those shown above) that can be used to trap cancer cells when blood passes through. A few years back, Mehmet Toner, a biomedical engineering professor at Harvard, created a device similar to the nano-forest that was less effective because silicon was used instead of carbon tubes. Today, Toner has teamed up with Brian Wardle, associate professor of aeronautics and astronautics at MIT, who together have redesigned the original microfluid device to work eight times more efficiently than its predecessor. The carbon nanotubes make diagnosis a fair bit simpler, largely because of the antibodies attached to them that help trap cancer cells as they pass through -- something that's being tailored to work with HIV as well. Things are starting to look moderately promising for cancer-stricken individuals, as hospitals have already began using the original device to detect malignant cells and ultimately prevent them from spreading -- here's hoping it's qualified for mass adoption sooner rather than later.
Harvard physicist puts fires out with electrified wand, hopes to share on HarvardConnection
Okay, so maybe Ludovico Cademartiri will be forced to share the good news on Facebook (or ConnectU, if he's into playing the role of rebel), but at least he's bound to see over a couple of hundred hits. According to The Harvard Crimson, the aforesaid physicist and a smattering of other researchers have stumbled upon a novel way to extinguish flames: electricity. The idea is eventually enable firefighters to squash fires without having to douse a home or object with water and foam -- if hit with a beam of juice, there's at least a sliver of a chance that something can be salvaged. While the specifics of the project are obviously far above our heads, the gist of it is fairly simple -- flames contain soot particles, which become "electrically charged during combustion." Given that those very particles react to electrical fields, a strong enough beam can twist things until it's extinguished completely. Quite honestly, it's a hands-on experience we're desperately trying to arrange, but till then, it looks like another round of Harry Potter will have to do.
Computer learning and computational neuroscience icon Dr. Leslie Valiant wins Turing Award
We've seen recently that computers are more than capable of kicking humanoids to the curb when it comes to winning fame and fortune, but it's still we humans who dole out the prizes, and one very brainy humanoid just won the best prize in computer science. That person is Leslie Valiant, and the prize is the fabled A.M. Turing Award. Dr. Valiant currently teaches at Harvard and over the years developed numerous algorithms and models for parsing and computer learning, including work to understand computational neuroscience. His achievements have helped make those machines smarter and better at thinking like we humans, but he's as of yet been unsuccessful in teaching them the most important thing: how to love.
Multi-core voltage regulator uses fast voltage scaling to curb your processor's wasteful habits
Your processor may be able to react to your every, fickle demand when it comes to churning out the numbers that make the magic happen, but when it comes to managing its own power it's a bit more lazy. Chips can throttle an individual core's consumption back, but do so slowly, a problem that Harvard grad student Wonyoung Kim appears to have solved. He's created an on-chip multi-core voltage regulator that uses what's called fast-voltage scaling, a technique of rapidly cutting power that could drastically extend battery life on mobile devices -- or, you know, make it so that your gaming rig doesn't dim the lights quite so badly when you crank it up to the gigahertz. No word on when this regulator will start making an appearance in consumer electronics, but Mr. Kim has achieved a patent for his work, so you can be sure he'll be making bank whenever it does.
$200 'Mini' NMR detects cancer faster and cheaper than full biopsies
Detecting cancer could be on the verge of getting a whole lot cheaper -- and better. Researchers at Harvard and MIT have come up with a device that, using a needle to get a tissue sample, has achieve 96 percent accuracy despite having a cost to produce of just $200. It's called a mini NMR (for nuclear magnet resonance) and also gives results in under an hour, giving the good or bad news on a smartphone display. The cost, simplicity, and portability could make it much easier for cancer to be caught and diagnosed early, but naturally it still has a good bit of testing left before it'll be ready for prime time.
Researchers from Harvard and MITRE announce world's first programmable nanoprocessor
We've seen plenty of breakthroughs involving nanowires over the years, but none of those have involved an actual programmable processor -- until now, that is. That particular "world's first" was just announced by a team of researchers from Harvard University and the MITRE Corporation this week, and it's being described as nothing short of a "quantum jump forward in the complexity and function of circuits built from the bottom up." As for the processor itself, it consists of an array of nearly 500 germanium nanowires that have been criss-crossed with metal wires on a chip that's just 960 micrometers (or less than 1 millimeter) square. That becomes an actual processor when the researchers run a high voltage through the metal wires and switch the individual intersections off and on at will -- we're simplyfing things a bit, but you get the idea. What's more, the researchers note that the architecture is fully scalable, and promises to allow for the assembly of "much larger and ever more functional nanoprocessors." Head on past the break for the official press release. [Thanks, Chris]
Harvard University controls worm with laser, we wait for choreographed dance moves (video)
Researchers at Harvard University's Center For Brain Science have successful manipulated nematode C. elegans worms by genetically modifying a select few of their 302 neurons. Not to be confused with magnetically controlled invertebrate, these creepy-crawlies are controlled by the CoLBeRT system (a nod to the comedian but no other relation), controlling locomotion and behavior in real time. The scientists can manipulate movement of the worms, induce paralysis, and even cause them to lay eggs all by shining a laser that turns on and off the modified cells at will. The laser hits the worm and causes it to react as if it were being touched. According to the researchers, the reaction is similar to when light is shined in a human eye -- the protein found in the worm and eyes are sensitive to different variations of rays and will respond based on the color shined. Peep past the break for some squiggly mind- er, light-controlled action.
