Strained graphene leads to pseudo-magnetic fields, bends physics even further
Man, if only this had been discovered before Ariadne was tasked with building impossible dreams. A team of scientists caught high-fiving over at Lawrence Berkeley National Laboratory have a new and riveting announcement to share, and it revolves around our old and trusted friend, graphene. This go 'round, the self-proclaimed "extraordinary form of carbon" is being stressed to its max, but not without good reason. Thanks to inquisitive minds and a "stroke of serendipity," a research team was able to create magnetic fields in excess of 300 tesla by simply straining graphene in a certain way. For physicists, the discovery is a dream come true, particularly when you realize that magnetic fields in excess of 85 tesla were practically impossible to come across in a laboratory setting. The benefits here? It's honestly too early to tell, but gurus in the field are already suggesting that the "opportunities for basic science with strain engineering [are] huge." Something tells us Magneto would concur.
Melting silicon 'in reverse' can help purify it, result in cheaper electronics
Just our favorite combination of news: a mind-bending innovation that can have a very practical impact on our daily tech consumption. MIT scientists have found that silicon -- when combined in the right dosage with other metals -- can actually be made to melt by reducing its temperature. Typically, you'd require 1,414 degrees of Celsius heat to liquidize solid silicon, but the intermixed variant discussed here need only reach 900 degrees before its slow cooling process starts turning it gooey. The great advantage to this discovery is that because the impurities tend to separate off into the liquid part, there's now a practicable way to filter them out, meaning that things like solar cells won't require the same high grade of silicon purity for their construction -- which in turn might lead to us being able to afford them one day. Of course, that's getting way too far ahead of ourselves, as the research is still ongoing, but good news is good news no matter the timescale.
Driverless vans set off on intercontinental trek from Italy to China (video)
You might not have expected the future to look like your granddad's groovy camper van, but take a closer look here and you'll find that this is indeed nothing like your forefather's people carrier. The VisLab team from the University of Parma have taken a fleet of Piaggio Porter Electric vehicles, strapped them with an array of cameras, lasers and other sensors, and topped them off with solar panels to keep the electronics powered. Oh, and lest we forgot to mention: the vans are (mostly) autonomous. VIAC (or VisLab Intercontinental Autonomous Challenge) is the grand name given to their big demonstration: an 8,000-mile, 3-month tour that will ultimately find them arriving in Shanghai, China, having set off from Milan this Tuesday. You can follow the day-by-day development on the blog below, though we're still being told that practical driverless road cars are a measure of decades, not years, away.
Vaccine-delivery patch uses microneedles to do its dirty work, looks good in testing
This dissolving microneedle patch has been in development for well over a year now, but Mark Prausnitz -- a professor in the Georgia Tech School of Chemical and Biomolecular Engineering -- along with a number of other GT and Emory University colleagues, have just now wrapped up a lab trial that brings it that much closer to market. As the story goes, this vaccine-delivery patch, which is based on hundreds of microscopic needles that dissolve into the skin, was recently seen as reliable in a round of mice tests, and the powers that be have also concluded that these patches would cost "cost about the same as conventional needle-and-syringe techniques, and may lower the overall cost of immunization programs by reducing personnel costs and waste disposal requirements." Oh, and did we mention that you could apply 'em on your own with little to no pain? FDA approval, we're waitin' on ya.
Sperm gene same as it was 600 million years ago, miraculously still in fashion
We've had a thing for sperm ever since Look Who's Talking broadened our appreciation for the reproductive arts, and now scientists at Northwestern's Feinberg School of Medicine have discovered a wealth of new information about the world's most adored swimmers. Believe it or not, we're now left thinking that they're even more hardcore. Yes, they've been rocking the exact same makeup -- called the Boule gene -- since the dawn of evolution. But as it turns out, that gene is also shared across a huge swath of organisms from humans to fish to fruit flies, and it's only ever used in sperm. This bodes interestingly for the future of reproductive sciences; researchers removed the Boule gene from mice and found that, while otherwise completely normal, they didn't produce sperm. We can almost feel that Gucci case for the male contraceptive pill in our man-purses now. [Photo courtesy of aSIMULAtor]
Scientists formalize perfect handshake; world peace on track for 2012
PH = (e² + ve²)(d²) + (cg + dr)² + π{(4< s >2)(4< p >2)}² + (vi + t + te)² + {(4< c >2)(4< du >2)}² Where (e) is eye contact (1=none; 5=direct) 5; (ve) is verbal greeting (1=totally inappropriate; 5=totally appropriate) 5; (d) is Duchenne smile - smiling in eyes and mouth, plus symmetry on both sides of face, and slower offset (1=totally non-Duchenne smile (false smile); 5=totally Duchenne) 5; (cg) completeness of grip (1=very incomplete; 5=full) 5; (dr) is dryness of hand (1=damp; 5=dry) 4; (s) is strength (1= weak; 5=strong) 3; (p) is position of hand (1=back towards own body; 5=other person's bodily zone) 3; (vi) is vigour (1=too low/too high; 5=mid) 3; (t) is temperature of hands (1=too cold/too hot; 5=mid) 3; (te) is texture of hands (5=mid; 1=too rough/too smooth) 3; (c) is control (1=low; 5=high) 3; (du) is duration (1= brief; 5=long) 3. It's that easy! Perhaps just as interesting is the fact that this formula was arrived at by University of Manchester scientists hired by Chevrolet "as part of a handshake training guide for its staff to prepare them ahead of the launch of the new 5 Year Promise offer, which aims to offer peace of mind and reassurance to its customers." Now excuse us while we go practice with our best friend for the rest of our useful lives. [Image courtesy of Aidan_Jones]
Breaking: chicken came before the (chicken) egg
Don't ask us why British researchers are spending their time trying to solve the age-old "who came first" conundrum, but apparently solve it they have done. Lab dwellers from the universities of Sheffield and Warwick share the distinction of identifying the particular effects of a particular protein -- ovocleidin-17, found only in chickens' ovaries -- on the development of the egg's shell. It would seem that without OC-17 converting calcium carbonate into calcite crystals, one couldn't have an eggshell, meaning that the chicken and its special protein powers had to have developed first. How the world's going to react to having one of its favorite clichés wrestled away has yet to be determined. Update: Seems like we didn't make it clear enough that these findings relate specifically to chicken eggs. We're well aware that dragons dinosaurs have plenty of prior art on chickens when it comes to laying shelled embryo chambers.
Revenge of the quadrocopters: now they move in packs (video)
In case you didn't find the original quadrocopter chilling enough, the GRASP Lab out of the University of Pennsylvania has gone and added a bit of cooperative logic to the recipe so that now multiple little drones can work together. Also upgraded with a "claw-like" gripper that allows it to pick up and transport objects, the newer quadrocopter can team up on its prey payload with its buddies, all while maintaining its exquisite balance and agility. Skip past the break to see it on video.
Intel's smart TV remote will recognize you, tailor content to your wishes
It's all about how you hold it, apparently. Intel's Labs have churned out a proposal for a new user-identifying system to be embedded into remote controls. Given a bit of time to familiarize itself with particular users, this new motion sensor-equipped channel switcher is capable of correctly recognizing its holder just by the way he operates it. Taking accelerometer readings every 100 nanoseconds, the researchers were able to build a data set of idiosyncrasies about each person, which would then be applied the next time he picked up the remote. Alas, accuracy rates are still well short of 100 percent, but there's always hope for improving things and for now it's being suggested that the system could be employed to help with targeted advertising -- which is annoying anyway, whoever it may think you are.
Stanford cuts down on clutter by removing 70,000 books from its Engineering Library
Guess this is one way to tighten your belt. Stanford University has opted to drastically reduce the catalog of physical volumes within its Engineering Library down from its original 80,000 to a svelte 10,000 copies. Before you cry foul and analogize between this and the prep school that threw out all its paper books, note that we're mostly talking about periodicals here, which tend to be used for quick references -- something that the newly digitized and searchable copies will probably make a lot easier. This action was prompted when the University noticed a large proportion of its leafy volumes hadn't left their shelves for over five years, and now the librarians are all aflutter with excitement about using the freed up space and resources for more productive causes. Such as educating us on the unappreciated benefits of indexing.
Eye-tracking lie detectors inch a little closer to reality
If lie detection is your thing, choices aren't exactly scarce: you can go with Lego for the kids, Skype-centric for remote fibber identification, or even use a headband if you can corral your suspect long enough. Hoping to add to that list is the University of Utah, whose eye-tracking lie detector has been licensed to a local company in order to explore its viability as a commercial product. As with Blade Runnner's Voight-Kampff empathy test, Utah's methodology revolves around monitoring things like eye movement, pupil dilation and response time -- with the major difference being that you're trying to identify truth evaders rather than skinjobs. John Kircher, one of the lead researchers, claims results so far have been as good as or better than those obtained with polygraph testing, though he admits the project is still in its early stages. No worries, though, we're sure they'll perfect the technique in time for our post-apocalyptic, Vangelis-scored future.
Artist uses GPS to map things the old-fashioned way: walking around
Back in the day, our homeboys Magellan, Lewis, Clark, Rand, and McNally didn't have anything better to do than walk around, look at stuff, and make some maps. Then along came people like Google, hell-bent on semi-automating via satellite what used to be a really down-to-earth task. In 2010, mapmaker and artist Jeremy Wood has found a way to get his kicks via satellite and pedestrianism. His latest project Traverse Me is a simple enough idea: walk around in the defined area with a GPS unit and end up with a 1:1 scale map of where he walked. Wood traversed the University of Warwick (avoiding paths and roads when possible) over 17 days and ended up with a plot of a very human-looking 238 miles. While they certainly aren't very useful for getting from point A to point B, Wood's maps unveil a weird new kind of topography. They don't particularly want to make us visit the University of Warwick, but we certainly wouldn't mind hanging prints of some of these bad boys on our living room walls.
Christie creates baffling 3D HD CAVE 'visual environment,' or your average Halo display in 2020
Whenever the word "Christie" is involved, you can generally count on two things: 1) you can't afford it and 2) you'll want to afford it. The high-end projection company is at it once again, this time installing a truly insane visual environment at Weill Cornell Medical College in New York. The 3D HD CAVE is intended to help researchers find breakthroughs in biomedical studies, and while CAVE itself has been around for years, this particular version easily trumps prior iterations. For starters, it relies on eight Christie Mirage 3-chip DLP projectors, all of which have active stereo capabilities and can deliver a native resolution of 1,920 x 1,920. Yeah, that's 3.68 megapixels per wall. The idea here is to provide mad scientists with a ridiculous amount of pixel density in an immersive world, but all we can think about is hooking Kinect and the next installment of Bungie's famed franchise up to this thing. Can we get an "amen?"
US Army eyes acoustic trapping for filtering bacteria from water
Don't bother asking "why" when it comes to governmental wishes -- just accept the fact that the US Army needs a more efficient way of filtering bacterial spores from water. All jesting aside, the actual process of filtering water and investigating what types of critters are swimming about is surprisingly complex, and currently, it still requires a good bit of human interaction to overcome clogs that frequently occur. Thanks to a little research going down at MIT, it's looking like sound may be the answer. Yeah, noise. The Army is funding a project that'll determine whether an acoustic standing wave would be able to jostle things in a way that clogs would be avoided, and if it pans out, mad scientists could even monitor water quality remotely. We told you telecommuting was a beautiful thing, now didn't we?
Inhabitat's Week in Green: street-legal Tron lightcycles, electronic eyeglasses, and the American Solar Challenge
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us. This week Inhabitat saw solar-powered vehicles blaze trails around the globe as the University of Michigan's sleek pod car crossed the finish line to win the American Solar Challenge. We also watched the Solar Impulse gear up for its first eagerly anticipated night flight -- a pivotal undertaking as the sun-powered plane prepares to circle the earth. In other clean transportation news, and we were stunned to see a set of street-legal electric Tron lightcycles pop up on eBay. The field of renewable energy also heated up this week as researchers revealed an innovative tri-layered solar panel that's capable of catching the full spectrum of the sun's rays. Wind power made waves as well as Principle Power unveiled a new ultra-sturdy ocean platform that's able to support the world's tallest wind turbines. Finally, we saw the light this week as Illumitex unveiled the world's first square LED bulb, which they claim is cheaper, more efficient and more practical than typical round bulbs. We also peered at an innovative new type of electronic eyeglasses that can change your prescription with the push of a button. And for all you shutterbugs looking to share your vision with the world, you won't want to miss this handy solar camera strap that ensures you'll never miss a shot.
Olympus E-330 shoots vacations by day, spots cancer cells by night
Yeah, that's right -- the first DSLR to ever ship with a live-view LCD on the back is now being put to use for something far more monumental, a full four years after it's original introduction. A smattering of researchers at Rice University have somehow discovered that the Olympus E-330 can be used to distinguish between cancerous and healthy cells, and there's no need to even export the photos; instead, the camera's own rear LCD is good enough to show whether or not a dyed cell is harmful or salubrious. The whole skinny is down there in the source link, but the takeaway is pretty staggering: if an off-the-shelf DSLR can now be used to make such profound decisions, why in the world are you still in med school?
iPhone 4 antenna problems were predicted on June 10 by Danish professor
Well, this must be one of the most epic "I told you so" moments in the history of consumer electronics. Professor Gert Frølund Pedersen, an antenna expert over at Denmark's Aalborg University, managed to get his concerns about the iPhone 4's external antennae on the record a cool two weeks before the phone was even released. In an interview on June 10, the Danish brainbox explained that he wasn't impressed by Steve Jobs' promises of better reception, describing external antennas as "old news," and suggested that contact with fleshlings could result in undesirable consequences to the handset's reception: "The human tissue will in any event have an inhibitory effect on the antenna. Touch means that a larger portion of antenna energy becomes heat and lost." Machine-translated that may be, but you get the point. Researchers at Gert's university have already shown that over 90 percent of any phone's antenna signal can be stifled by holding it in the right place, but he's highlighting the specific exposure to skin contact as a separate issue to be mindful of. Good to know we've got sharp minds out there, and as to his suggested solution, Gert says phones should ideally have two antennae that act in a sort of redundant array, so that when one is blocked, the other can pick up the slack. So, what are we going to do now, Apple? [Thanks, Andrew]
Self-assembling nanodevices could advance medicine one tiny leap at a time
Seems like Harvard wasn't content with making robotic bees, and has taken its quest for miniaturization right down to the nanoscale level. One nanometer-wide, single-stranded DNA molecules are the topic of the university's latest research, which sets out a way they can be used to create "3D prestressed tensegrity structures." Should these theoretical scribblings ever pan out in the real world, we could see the resulting self-assembled nanodevices facilitating drug delivery targeted directly at the diseased cells, and even the reprogramming of human stem cells. Infusing a nanodevice with the relevant DNA data passes instructions on to your stem cells, which consequently turn into, for example, new bone tissue or neurons to augment your fleshy CPU. Yes, we're kinda freaked out, but what's cooler than being able to say you're going to the doctor for a shot of nanotransformers?
Graduation cap modded with LED array, steals show (video)
Yomo Gaocho, an enterprising young man about to graduate from Northwestern University, has put together pretty much the coolest grad cap mod we've seen. Not that we're experts on the subject or anything, but the array of 256 LED lights adorning his cap surely makes for one of the geekiest ways to bid adieu to one's undergraduate studies. He's taking it one step further too, by programming animation patterns into the white LED arrangement and offering advertising space -- we're not kidding -- for any unorthodox companies that may wish to have him as a walking billboard. See Yomo's creation on video after the break, or hit the source for a guide on how to make your own light-fantastic grad cap.
Autonomous quadrocopter flies through windows, straight into our hearts (video)
We don't know whether we should be terrified or overjoyed. We've just come across a video demo from the University of Pennsylvania's GRASP Lab that shows an autonomous quadrotor helicopter performing "precise aggressive maneuvers." And trust us when we say, nothing in the foregoing sentence is an overstatement -- the thing moves with the speed and grace of an angry bee, while accompanied by the perfectly menacing whine of its little engine. See this work of scientific art in motion after the break. [Thanks, William]
