Ohio test uses drones to monitor highway traffic
Highway traffic monitoring is frequently... less than efficient. Fixed cameras can't catch problems beyond their immediate location, while aircraft are both costly and inevitably have to fly back to a distant base to refuel. These systems may soon get a robotic upgrade, though. Ohio State University is leading a pilot program that will use drones for roadway and traffic monitoring along a 35-mile highway stretch (the Smart Mobility Corridor) between Dublin and East Liberty. The dry run will see drones feed tracking data to the Ohio Department of Transportation's Traffic Management Center to complement data from existing systems. If there's a traffic-disrupting crash or a washed-out road, this might help spot it sooner.
'Hovering' antennas promise speedy 5G phone networks
Wireless networks already have to deal with increasingly crowded waves, and that's only going to get worse when 5G rolls around. Any boost to the signal could lead to a big jump in performance, especially when you're using very high frequencies that are more prone to interference. But how do you provide that boost? Researchers have an idea: 'hover' the antenna. They've developed millimeter wave antenna arrays that are almost entirely separated from the substrate you'd usually mount them on, preventing that substrate from weakening the signal like it does with conventional antennas.
Fingernail-sized chip can repair damaged tissue in seconds
A new device can begin repairing damaged organs in seconds, heralding a major breakthrough for life-saving medicine. Developed at Ohio State University, the technology known as tissue nanotransfection (TNT) uses a small coin-sized silicon chip that "injects" genetic code into skin cells, converting them from one type to another.
Mechanical 'trees' generate energy by swaying in the wind
What if windmills looked more like trees? Well, a team of engineers at Ohio State University is looking for answer to that question with structures that resemble trees, but actually create energy when they move in the breeze. That swaying motion from the wind, and the resulting structural vibrations, is converted into electricity with electromechanical materials such as polyvinylidene fluoride (PVDF). The project isn't merely concerned with those tree-like structures, though. It also looks to harvest the energy generated from the vibrations of buildings and bridges.
The Daily Grind: Does your MMO character reflect you or the other way around?
Last summer, we reported on research that suggested people's behavior changes because of the proportions of the characters they were assigned to play. This week, we saw related results from a Stanford/OSU team that posed a similar question in relation to sexualized avatars in online settings like MMOs. The researchers tested the "Proteus effect," finding that subjects who were assigned hyper-sexualized avatars in a virtual setting "internalized" their avatars' appearance, focusing more on body image and expressing more "rape myth acceptance" than the control group. Setting aside the obvious implication that playing a sexed-up toon in an MMO might temporarily darken our mental health, I have to wonder what other bad habits we might be learning from our characters. How much control do we really have when we roll up a new avatar in an MMO? Did I choose to roleplay a snarky pirate in that last game because it would be fun or because I have a problem with authority and a rude attitude I needed a way to express? Worse, did her negative traits and wardrobe rub off on or change me? Do you think your MMO character reflects you, or do you think you subconsciously reflect your MMO character? Have you ever found yourself picking up or dwelling on the attributes of your characters? Every morning, the Massively bloggers probe the minds of their readers with deep, thought-provoking questions about that most serious of topics: massively online gaming. We crave your opinions, so grab your caffeinated beverage of choice and chime in on today's Daily Grind!
Researchers create super-efficient microbial fuel cell, dream of selling excess electricity
Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and selecting better microbes, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons -- rather than the hydrogen or methane that other methods rely upon -- are produced and run from an anode to a cathode within the device to create an electric current. Once implementation costs are cut down, the technology could power waste treatment plants and enable them to sell excess electricity. The contraption isn't just for processing what comes out of the porcelain throne -- it can also utilize materials ranging from grass straw to beer brewing byproducts. For now, however, the cell will tackle a pilot study before it inches closer to your local brewery or water treatment facility.
Buckeyes to fire 500 trillion watt laser May 15th in a short, cheap burst
High-energy laser fusion experiments evoke extreme numbers -- not only in power but also in greenbacks. Sure, the current champ at the National Ignition facility in Livermore, CA can pump out a 411 trillion watt pulse, but at what price? A taxpayer-busting $200,000 per shot, with a $4 billion original construction cost. Compared to that, the new Ohio State University's 500 trillion watt model seems bargain-basement, built with a mere $6 million grant from the US Department of Energy. Admittedly, that paltry sum get you a much shorter burst, lasting 20 picoseconds compared to the NIF's several nanoseconds. But with the ability to fire 100 or more times per day, instead of just once like it's pricier kin, Ohio State will be able to assist the NIF with their fusion experiments, while also carrying on its own science, like simulating star formation. And money aside, the possibility of unlimited fusion-powered energy is always a noble goal, no?
Six-rotor drone counts trees, not kills
Relax everybody, unlike its antonymous quadrocopter cousins, this six-rotor drone isn't here to kill, only to count plants. Researchers from Oregon State University are hanging cameras from reasonably-priced RC aircraft to help nurseries track inventory -- a task often performed by workers wandering the orchards and keeping tally by hand. Image analysis software automates the process and, with the addition of other sensors (such as infrared), it could one day be used to spot irrigation problems, identify diseased trees, and estimate crop yield. The machines themselves can climb to over 80 feet and stay aloft for up to 40 minutes while hauling 5-pounds of photo gear. At around $10,000 it's a safe bet that no one will be shooting bottle rockets at balloons with this thing, but it should be well within the reach of farmers who spend that much in money and manpower to track their trees anyway. Two more photos after the break.
OSU Buckeye Bullet 2 sets new battery-powered speed record
Ohio State's Buckeye Bullet 2 has just set a new battery-powered vehicle record after hitting a speed of 291 mph averaged over two separate runs done back-to-back in opposite directions. Yes, it's technically slower than the two-way land speed record of 300.992 mph the original Bullet set back in 2009, but that car was powered by hydrogen fuel cells. This year's model instead was developed in partnership with boutique Monaco-based electric car manufacturer Venturi and replaced the fuel cells with lithium-ion batteries from A123 Systems. It's also apparently a testing prototype for a new car that's coming in 2011. Will that car hit these kind of world record speeds? Probably not, but we're not letting that dash our newly formed geek fantasy of seeing it drag against a Tesla.
Oklahoma State University to start up iPad initiative
Oklahoma State University is the latest school to start setting students up with iPads. Starting this fall, a pilot program will give iPads to 125 students, and the university will monitor both how the device affects their learning and what their textbook costs turn out to be. Additionally, the classes in the pilot program will look at using both apps and Web-based tools on the devices, as is appropriate for the classroom. What's interesting is that, instead of just handing out iPads to the students, OSU is really interested in how their students will go about using them. The results should be intriguing, not only for the lucky college kids who get to use iPads all semester but also for Apple and for other schools that are formulating plans over how to share and use technology. It certainly seems like having an iPad at college would be helpful in the traditional ways (you could read textbooks or take notes on it), but it's cool that OSU is thinking about new ways to use it as well, such as apps for tests or connections across local Wi-Fi for networked learning. We'll see how OSU's program works out. The iPad is certainly a new kind of computer, and it sounds like OSU is looking for new ways of using it on campus.
Pentax Kameraman puppets are perfect for shooting WTF faces
We don't know how seriously you take yourself as a photographer. But painting a face on your lens cap and dangling a hand-made, ¥2,914 (about $32) Osu! Kameraman puppet from your camera's tripod mount isn't going to earn you much respect. Especially when your telephoto lens is dialed up to maximum, perv. Perfect though, if you're only hoping to capture faces twisted into a scowl. Entire collection on display after the break.
Paparazzi Bots will chase you down until you love them
Sony's Party-shot dock is fun and all but it suffers from one major limitation: it's fixed in space. Oh sure, it'll pan and tilt around its base until the last reveler is unconscious, but it won't go to where the action is. That's where the Ohio State University developed Paparazzi Bot comes in. The autonomous, sensor-laden, mobile robot stands at human height and decides for itself whether or not to snap your photo based upon your facial expression (hint: it likes smiles). If chosen, the bot stops, aims, shoots and uploads your image to a social networking site for other robots to mock, presumably -- a kind of fleeting celebrity anointment as described by the bot's inventor, Ken Rinaldo; or a kind of precursor to robots with automatic weapons, if you ask us. Video demonstration after the break.
OSU foresters swap tree fibers for rubber in fuel efficient tires
Leave it to a gaggle of brilliant wood science researchers at Oregon State University to figure out that we've been doing this whole "tire" thing wrong for generations now. While studying some uses of microcrystalline cellulose, which can be made easily from practically any type of plant fiber, these Earth-loving gurus discovered that said material could actually improve the efficiency of vehicle tires when used in place of silica. Granted, only about 12 percent of the silica -- which is used as a reinforcing filler in the manufacture of rubber tires -- was swapped out, but the resulting tires gripped just as well in wet weather while decreasing the rolling resistance during those dry summer months. Furthermore, tires constructed with these fibers could be made with less energy, though long-term durability studies are still needed to prove that this whole plan is viable for more than a few thousand miles.

Another team figures out how to convert waste heat into energy
Not that mad scientists haven't figured out a way to convert waste heat into energy, but a team from Ohio State University has developed a new material that does the same sort of thing... just way, way better. The new material goes by the name thallium-doped lead telluride, and at least in theory, it could actually convert exhaust heat from vehicles into electricity. According to a new report about to hit the journal Science, the material packs "twice the efficiency of anything currently on the market," though it still seems as if it's a good ways out from being ready for commercial applications.

OSU researcher developing GPS-like system for moon-bound astronauts
GPS on the moon may seem a bit far-fetched... that is, until you remember the US military's plans to launch a WiFi router into space. The same Ohio State University researcher who developed software for the Mars rovers Spirit and Opportunity is now developing a GPS-like system that would enable astronauts to navigate terrain as if they were simply routing themselves through a plot of land on Earth. Because of the moon's location (we're simplifying things here), Ron Li is having to create a similar system (read: not bona fide GPS) that relies on "signals from a set of sensors including lunar beacons, stereo cameras, and orbital imaging devices" in order to provide navigational output. Everyone involved is hoping to have it operational by 2020 (the next planned trip to the moon), but the team will be stuck testing in the Mojave Desert. Bummer.[Via Physorg]
OSU and DARPA building UAV nano planes that can fit in a pocket
A fancy new miniaturized plasma propulsion system being developed at Oklahoma State University promises some exciting new Unmanned Ariel Vehicle spy plane designs for the folks at DARPA. The engine is about the size of a cigarette, contains no moving parts, and will be build into planes as small as 6-inches long, which soldiers can carry in packs of six or so and deploy as a swarm of inquisitive Daniel Craigs. The planes should be able to manage indoors and urban areas. No word on when these will be spying on a homeland security threat near you, but the project is still in the early stages. [Via Crave]
Free PC Ouendan/EBA emulator hits public beta
One thing you can count on for any decently successful rhythm game: someone will figure out a way to make a free PC clone. First there was Stepmania for DDR players, then there was Frets on Fire for Guitar Hero shredders and now there's Osu! for Ouendan/Elite Beat Agents fans. The public beta, available since yesterday, does a remarkable job of capturing the tap-out-the-rhythm gameplay of the DS games, though the dancing cheerleaders have been replaced with static videos for each song. You can build your own levels or download over 100 "beatmaps" of primarily J-Pop songs that were made by testers. Casual fans beware -- a lot of these fan-designed levels are killer, though there is an easy mode that makes things a little more manageable. Even if you're a master at the DS games, using the mouse takes a little getting used to. Then again, if you have a tablet PC, it's probably just like the DS games. Except, er, bigger.
Ford Fusion Hydrogen 999 breaks 200 miles-per-hour
Looks like minuscule RC cars aren't the only alternatively powered vehicles trying to break 200 miles-per-hour, as Ford just became the "world's first automaker to set a land speed record for a production-based fuel cell powered car." The whip used to set the bar, of course, is none other than the Fusion Hydrogen 999, and it reportedly reached over 207 miles-per-hour at the Bonneville Salt Flats in Wendover, Utah without using a drop of gas. Apparently, Ford is hoping that this showcase of speed will somehow translate into advancements that will help us common folk get to work and back sans gasoline, and while we've no idea when a fuel cell propelled Cobra will roll off the line, it did note that a number of fuel cell propelled Focus vehicles were still burning down the roads as part of an ongoing study.[Via AutoblogGreen]
DS Daily: OUENDAAAAAAN
It's out, and we don't have it. It kinda hurts. Some bloggers seem to have gotten their hands on a copy, so we know it's possible that one of our faithful readers has Moeru! Nekketsu Rhythm Damashii Osu! Tatakae! Ouendan 2! We need to live vicariously through you, hypothetical reader! We need your impressions! Those of you who don't have it or just don't have it yet: do you have one on the way? Do you consider this the biggest game release of the year? Or are you holding out for a US release? Or an Elite Beat Agents 2: Beat Harder? Personally, we'll take any and all iNiS music releases and will be importing Ouendan 2 as soon as finances allow.
New Ouendan 2 screens: versus mode CONFIRMED, excitement UNCONTROLLABLE
Some incredible new screens of Ouendan 2 have exploded onto the web and filled us with hot-blooded rhythm spirit. Two new scenarios are featured: the first involving a girls' choir who need HEEEAALP performing harmoniously, and the second involving a soccer player who requires the power of your dancing to succeed. Wait, cheering for a sport? Preposterous.One especially notable feature evident in the screens is a new multiplayer mode, where one member of both the Ouendan squad and the new rival squad face off. Judging from the little antenna icon on the screen, it's definitely wireless play. Our case of rhythm spirit will be incurable if the game turns out to be online.
