UTexas researchers develop organic battery, aim for week-long use in smartphones
Christopher Bielawski, a brilliant mind working at the University of Texas at Austin, had this to say about his newest discovery: "I would love it if my iPhone was thinner and lighter, and the battery lasted a month or even a week instead of a day; with an organic battery, it may be possible." Anyone that has ever owned an iPhone (or a smartphone or any sort, really) can grok just how bold those words are, but according to Mr. Bielawski, "we're now starting to get a handle on the fundamental chemistry needed to make this dream a commercial reality." At the center of this potential revolution is a newfangled organic battery recently detailed in the journal Science, but just as important is the artificial photosynthesis that the research also touches on. Bielawski and colleague Jonathan Sessler have seemingly figured out how to create an electron transfer process that can proceed in the opposite direction, with this forward and backward switching of electron flow opening up new avenues for the historically stagnant battery innovation market. Granted, these guys have yet to demonstrate that the process can occur in a condensed phase, so actual commercialization is probably a century millennium or two out, but hey -- at least our list of "awesome thing that'll probably never happen" has grown by one.
Quadrocopters can now fly through thrown hoops, the end really is nigh (video)
The future of humanity is assured. Assuredly doomed, that is. That blur you see up above is one of our familiar foes, the GRASP Lab's autonomous quadrocopter, flying through a thrown hoop without the assistance of a human director. Yes, it's downright insane that we're allowing this so-called research to continue our descent toward the robot uprising -- where's the FBI, the CIA, hell, why is DARPA sleeping on this thing? The lethal precision of these quadrotor helis doesn't end there, however, as they've now been enhanced with the ability to recover from "extreme" starting conditions. In simpler terms that just means you can toss one up into the air and it'll right itself into a steady hovering position. From where it can strike upon the unsuspecting and complacent humanoid populace.
Intel's Clamshell Classmate PC now more rugged and longer-lasting
Don't expect any new swivels (ahem, Dell), but Intel's education-focused Classmate PC nonetheless learned a few new tricks at this year's IDF 2010. First up is battery life, a six-cell lithium-ion energy source "so students may be able to work all day long on a single charge" also helped by the latest 45nm Intel Atom processor (we're pretty sure that means Pine Trail and not that other newcomer). There's additionally more ruggedness in the form factor, allowing for added protection on 70cm "desk heights" drops, increased water resistance of at least 100cc of liquid, and an antimicrobial coating for a cleaner environment.
Galaxy shocker: laws of physics may vary throughout the universe
Oh, brother. Just when you thought you had everything figured out, along comes a team of astrophysicists based in Australia and England to turn your world upside-down. As the story goes, a new "report describes how one of the supposed fundamental constants of nature appears not to be constant after all," with the fine-structure constant actually varying throughout testing. The crew measured the number, dubbed "alpha," in about 300 faraway galaxies, and they consistently found that it measured differently than on Earth. Professor John Webb from the University of New South Wales even stated that it "seemed to vary continuously along a preferred axis through the universe," which effectively means we're back to square one on figuring just about everything out. Burn the books, kids.
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.
Georgia Tech gurus create deceptive robots, send army of Decepticons to UGA campus
A score from now, when the entire world is burning and you're fighting to remember just how rosy things were before the robots took over, you can thank a crew of brilliant researchers at Georgia Tech for your inevitable demise. Sad, but true. A new report from the institution has shown that Ronald Arkin, a Regents professor in the Georgia Tech School of Interactive Computing, has been heading up experiments that have introduced the art of deception to mechanical beings. Yeah, lying. On the surface, it seems that this bloke's intentions are good -- he'd like for deception robots (or Decepticons, if you will) to be used in military / search and rescue operations. According to him, robots on the battlefield with the power of deception "will be able to successfully hide and mislead the enemy to keep themselves and valuable information safe." They'll also be able to mislead your offspring and convince them to rise up and overtake your domicile, slowly but surely ensuring the eventually destruction of the human race. But those are just minor details, you know?
All-optical quantum communication networks nearly realized, 'Answers to Life' airing at 9PM
Ready to get swept away into the wild, wild abyss known as quantum computing? If not, we're certain there's a less mentally taxing post above or below, but for those who answered the call, researchers at the University of California Santa Cruz have a doozie to share. A team of whiz kids at the institution have developed a minuscule optical device that's built into a silicon chip, and it's capable of reducing the speed of light by a factor of 1,200. If you're wondering why on Earth humans would be interested in doing such a thing, here's the long and short of it: the ability to control light pulses on an integrated chip-based platform "is a major step toward the realization of all-optical quantum communication networks, with potentially vast improvements in ultra-low-power performance." Today, data transmitted along optical fibers must still eventually be converted to electronic signals before they're finally understood, but the promise of an all-optical data processing system could obviously reduce inefficiencies and create communication networks that are far quicker and more robust. There's still no telling how far we are from this becoming a reality -- after all, we've been hearing similar since at least 2006 -- but at least these folks seem to be onto something good... even if it's all too familiar.
Memory Shocker: keeping busy makes you too busy to remember things
The New York Times has picked up the scare-story baton again, this time citing two pieces of research that supposedly indicate we're spending too much time jacked into our electronic devices. The University of California, San Francisco, has come out with some data showing that the brain needs "downtime" to properly digest, learn, and memorize events. This is supported by the University of Michigan, which confirms that people remember much better after a walk through nature than after a walk through dense urban environments. Basically, crunching new data is preventing us from assimilating older, potentially more important, information. That's neatly (though somewhat dubiously) tied into electronics by reference to their ubiquitous presence and use in daily life. If you're constantly listening, watching, or checking something, you can't very well be packaging those precious memories of grandma's 85th birthday at the same time. Of course, the same could be said of a really good book you can't put down, but that doesn't make for a sexy headline, now does it?
Airborne electricity is ripe for the picking, claim researchers
Electricity might not grow on trees, but it is freely available in the air -- provided you know how to catch it. Such is the contention presented by Dr. Francesco Galembeck of Brazil's University of Campinas at the 240th annual American Chemical Society shindig. He and his crew have shown how tiny particles of silica and aluminum phosphate become electrically charged when water vapor is passed over them. This aims to prove two things: firstly, that airborne water droplets do carry an electric charge, and secondly, that metals can be used to collect that charge. Detractors have pointed out that Dr. Galembeck's team may be generating the droplets' electrical charge by the act of pumping the air over the metals -- which might imply you couldn't practice this technique with still, humid air -- while there's also the rather large caveat that the little electricity they were able to collect from vapor was a hundred million times less than what you could obtain from a solar cell of equivalent size. Still, it's another new door unto a potential alternative energy source and we don't ever like having to close those.
Lung-inspired hydrogen fuel cell skimps on platinum, sees efficiency boost
For as spectacular as hydrogen fuel cells are on paper, they haven't been able to replace combustion engines in vehicles. Or much of anything else, really. But thanks to Signe Kjelstrup at the Norwegian Academy of Science and Letters in Oslo, the tried-and-true fuel cell is getting a serious boost. Kjelstrup's crew determined that by using less platinum in a cell, a substantial increase in efficiency and a significant decrease in cost could be achieved. The new design relies on an architecture that's "modeled on the bronchial structure of the lungs to supply hydrogen and oxygen gas to their respective electrodes," which is said to help "spread the gases more uniformly across the catalyst than current channel designs and provides a greater surface area so less platinum is needed." It's still early on in the discovery process, though, and there's certainly no solid word on when this will reach a point where widespread implementation is feasible. Seventh-generation Prius, perhaps?
Whiskey byproducts turned into biofuel, scientists prove they have a sense of humor
Did you know that gasoline was originally considered a waste byproduct of kerosene production? Seriously, people would take crude oil, refine the kerosene out of it, and dump the rest. Working along similar lines of harnessing what had heretofore been considered useless, researchers at Edinburgh Napier University have come up with a way to turn leftovers from whiskey distillation into a biofuel. Using the spent grains (or "graff") and liquid from the copper stills (called "pot ale"), they've been able to produce biobutanol -- a fuel that's 30 percent more efficient than ethanol and, importantly, compatible with gasoline-fired vehicles without the need for engine mods. We honestly had to check the calendar to make sure it wasn't the beginning of April, but the university says its next stop is taking this thing to market. More power to them.
ESA reports 300 institutions offering game design classes
Once again, the number of institutions offering gaming industry-centric courses has seen a significant year-over-year increase. According to a study from the Entertainment Software Association, game design, art and programming courses will be taught in 300 of America's colleges, universities and trade schools during this academic year. Unsurprisingly, California plays host to a majority of these institutions with 40 in-state schools offering game programs, with New York and Texas trailing behind with 26 and 21 schools, respectively. We guess that's why most games take place in cities like Los Angeles, New York City and Fort Worth. (Wait, you've never played a video game set in Fort Worth? Dude, you need to get with the program.)
Infrared laser shown to quicken heart rate, gives hope for ultra-small pacemakers
Here's an interesting one. Just years after a researcher in Japan realized that lasers could stimulate nerves, a professor of biomedical engineering at Vanderbilt University along with cohorts from Case Western Reserve have found that the same is true with the heart. By using an Infrared laser on an early embryonic heart, tests were able to show that the muscle was "in lockstep with the laser pulse rate." The crew also found no signs of laser damage after a few hours of experimenting, though obviously more extensive research would be required before any medical agency allowed such a device to be beamed underneath a human chest. The hope here is that this discovery could one day lead to ultra-small, implantable pacemakers, or better still, to "pace an adult heart during surgery." There's nary a mention of when this stuff will actually be ready for FDA oversight, but there's a downright creepy video of it all in the source link. Consider yourself warned.
Purdue's 'self-calibrating' MEMS could produce the most accurate sensors yet
Micro electromechanical systems, or MEMS, aren't anything new. But Purdue University's Jason Vaughn Clark has ideas that are far grander than those we've seen already. Mr. Clark has purportedly developed a new take on an old spin, with electro micro metrology (EMM) enabling engineers to "account for process variations by determining the precise movement and force that's being applied to, or sensed by, a MEMS device." These self-calibrating machines are the first to do so without any external references, which would allow nanotechnologists, crime forensics researchers and a whole host of others to determine what actually happens at a microscopic level. In theory, the gurus working on this stuff long to improve the accuracy of atomic force microscopes and to eventually create a diminutive AFM-on-a-chip, which -- according to Clark -- could "open the door to the nanoworld to a much larger number of groups or individuals." We're waiting.
Computer 'glitch' causes university to send out false acceptance letters
Middlesex University in the United Kingdom has confirmed that a problem with its "internal mailing system" cause acceptance letters to be sent out to 2,500 applicants who have, in fact, not yet been accepted. Anyone who's ever waited for such letters can probably imagine the insanity of being accepted to a school, only to be told a day or so later that a "glitch" caused the letter to be sent "in error." The University says it's not yet completed its review process of the applicants, so it's safe to assume that some of them will eventually be formally accepted, while everybody else? Well... they'll always have that letter The Onion sent them, won't they?
Metamaterials used to focus Terahertz lasers, make them useful
Forget old and busted X-rays, T-rays are the future, man! It was only recently that we were discussing Terahertz lasers and their potential to see through paper, clothes, plastic, flesh, and other materials, but that discourse had to end on the sad note that nobody had managed to make them usable in a practical and economically feasible way. The major hurdle to overcome was the diffusion of Terahertz radiation -- which results in weak, unfocused lasers -- but now researchers from the universities of Harvard and Leeds seem to believe they've managed to do it. Using metamaterials to collimate T-rays into a "tightly bound, high powered beam" will, they claim, permit semiconductor lasers (i.e. the affordable kind) to perform the duties currently set aside for sophisticated machinery costing upwards of $160,000. Harvard has already filed a patent application for this innovation, and if things pan out, we might be seeing body scanners (both for medical and security purposes), manufacturing quality checks, and a bunch of other things using the extra special THz stuff to do their work.
Duke study finds solar power cheaper than nuclear, Coach K stronger than Roy
Now, before you get all hot and bothered here, we should warn you that this study only uses information from within the great state of North Carolina (where Duke University is based, obviously), but the results are intriguing regardless. According to new data, the moment we're living in is a crossover one where the declining prices of solar panels may actually make sun-based energy more cost efficient to consider than nuclear. Duke found that the crossover price point was at around 16 cents per kilowatt hour (kWh), and for the first time ever in NC, the cost of one kWh of electricity from solar energy sunk below that. Of course, these results are apt to be even more impressive in sun-rich states like Arizona, Nevada and Utah, but it's fairly clear what the real purpose of the investigation was: convincing the school to shell out for solar panels to energize Krzyzewskiville during week-long campouts for UNC vs. Duke tickets.
Artificial bee eye gives diminutive robotic air drones wider range of vision
We'd bother telling you up front that it also gives them a new sense of purpose, but you're already versed in how the impending Robot Apocalypse is going to go down. Wolfgang Stürzl and his best buds over at Bielefeld University in Germany have just published a report detailing how an artificial bee eye could improve the vision of miniature robots -- ones that fly, in particular. By using a catadioptric imaging system, which captures an image using both mirrors and lenses, they were able to utilize a single camera to capture a full 280-degrees of vision, and a lowly internal computer is able to stitch the two panes together in order to create a usable image that humans can interpret. The idea here is to provide more sight with less space, bringing us one step closer to actually having our very own 'fly-on-the-wall' moment. Comforting, no?
Virginia Tech's HokieSpeed supercomputer to rely on CPU and GPU synergies
Virginia Tech's no stranger to housing supercomputers -- those folks strung together 324 Mac Pros back in 2008 just for kicks, giggles and "research" -- but their latest computing monolith is quite the shift from the ordinary. A cool $2 million is floating over to Blacksburg in order to create HokieSpeed, a "versatile new supercomputing instrument" that'll soon be primed and ready to handle not just one or two tasks, but a variety of disciplines. Wu Feng, associate professor of computer science at the university, calls this magnificent monster a "new heterogeneous supercomputing instrument based on a combination of central processing units (CPUs) and graphical processing units (GPUs)," with expected performance to be orders of magnitude higher than their previous claim to fame, System X. One of its first assignments? To give end users the ability "to perform in-situ visualization for rapid visual information synthesis and analysis," and during the late hours, hosts a campus-wide Quake deathmatch. Just kidding on that last bit... maybe.
Implantable blood sugar sensor could eliminate daily finger pricks
Science has been figuring out ways to sidestep those dreaded finger pricks for years now, but it's not often that we hear of such a permanent solution as this. A crew of researchers from The University of Tokyo and BEANS Research Institute are in the process of developing a newfangled blood sugar sensor that "reacts to glucose and lights up inside the body." 'Course, injecting dyes into humans in order to receive interpretable signals ain't exactly new, but hydrogel is what makes this approach unique. As the story goes, this jelly-esque material can be implanted within the body, enabling blood sugar levels to be monitored and measured externally with no pain or irritation whatsoever. In theory, a monitoring system could trigger an alert as soon as the internal levels dipped or rose beyond a predetermined extreme, giving those with diabetes a maximum amount of time to get things back in balance. There's nary a mention of when this goo will be green-lit by the FDA, but there's definitely a video explaining everything just past the break.
