Texas A&M researchers concoct nanoparticles to soak up crude oil spills
The 2010 Deepwater Horizon may be forgotten to many, but remnants of its destruction still remain in the Gulf of Mexico. Mercifully, it appears that researchers at Texas A&M University "have developed a non-toxic sequestering agent-iron oxide nanoparticles coated in a polymer mesh that can hold up to 10 times their weight in crude oil." In layman's terms, they've engineered a material that can safely soak up oil. As the story goes, the nanoparticles "consist of an iron oxide core surrounded by a shell of polymeric material," with the goal being to soak up leftover oil that isn't captured using conventional mechanical means. The next step? Creating an enhanced version that's biodegradable; as it stands, the existing particles could pose a threat if not collected once they've accomplished their duties.
LinkedIn launches University Pages, helps students learn more about colleges
LinkedIn has already branched out a bit with its own blogging and following features for select groups, and now the popular social networking site has introduced a tool geared towards students. Aptly dubbed University Pages, LinkedIn describes the new service as one that's part of its strategy to help college-bound pupils "at every critical milestone from campus to fulfilling successful careers." Beginning September 12th, LinkedIn's set to welcome high school students on its network and provide access to the new University Pages, allowing them to explore and rub elbows with about 200 participating universities, both in the US and abroad. Users will then be able to do things such as receive regular updates about campus news / activities and view notable members of each college's alumni. If one of your favorite schools isn't there just yet, fret not -- LinkedIn says "thousands more" will be given access over the next few weeks.
University of Texas students send yacht off-course with GPS exploit (video)
Students from the University of Texas gave us another reason not to mess with the Lone Star state: they'll hack your yacht. In cooperation with a luxury boat's owners, the Longhorns manipulated their $80 million vessel's nav system, covertly guiding it off-course -- all without the crew ever suspecting foul play. By transmitting spoofed global positioning system signals toward the craft, the students tricked its drivers into correcting a non-existent, three-degree course deviation, thus leading them off track. With their work done, the Texans believe this shows exactly how easy it is to exploit civil-band GPS signals. College kids may have conned the helm this time, but it isn't too far-fetched to think pirates could do the same. Our timbers are shivering just thinking about it.
Negobot: a virtual chat agent engineered to trap pedophiles
Online chat agents are far from novel, but they're evidently getting a lot more sophisticated with age. In a bid to trap pedophiles, engineers at the University of Deusto have concocted Negobot. Essentially, the tool employs game theory in order to meticulously extract vital identification nuggets from a suspected abuser. In order to disguise itself from being a digital representation of a child, it actually employs seven different conversational agents, with each having its own way of behaving. In use, the program begins with a neutral stance that it can maintain indefinitely, and if the subject shows interest, it can elevate its approach in an attempt to get said subject to give himself / herself up. Developers are still working on language and linguistic abilities, but we wouldn't be shocked if it ends up being put to use by certain agencies in the very near future.
SMI, others to use Champions League final as eye-tracking experiment
It may be the most watched sporting event, but SMI's more interested in how we watch the Champions League final than the game itself. The eye-tracking firm, in participation with the KMRC and University of Tübingen, will observe how 61 fans watch the Dortmund/Bayern tussle using its RED-m cameras. The project aims to discover if supporters of rival clubs perceive matches differently and, by tracking their eye movement, learn how those perceptions are formed. Of course, given our violently hysterical reactions when Didier Drogba sunk the winning penalty in last year's game, the researchers might have difficulty keeping the participants still enough to monitor.
University student crafts app that helps blind smartphone users snap photos
Dustin Adams, a Ph.D student at the University of California at Santa Cruz, has teamed up with colleagues at his school in order to craft an app that helps visually impaired users line up the ideal snapshot. The project started out as a quiz, asking 54 people with varying degrees of ocular impairment what they found most difficult about taking photos. From there, he essentially boiled that down into requirements for a smartphone program. For starters, the app does away with a conventional shutter button, instead relying on an upward swipe gesture to grab a frame. Moreover, it integrates face detection and voice accessibility, enabling the phone itself to talk to the photographer and alert him / her as to how many faces are detected and in focus. The app also captures a 30-second audio clip whenever the camera mode is activated, which helps remind users of what was going on during the capture of a shot. Unfortunately, there aren't any screenshots or videos of the app in action just yet, but that's scheduled to change when it's formally unveiled at the Pervasive Technologies Related to Assistive Environments conference in Greece later this month.
Lenovo ThinkPad Helix starts shipping, Seton Hall University gets early units
Lenovo's ThinkPad Helix has had one of the rockier roads to the US market, having been promised for February only to be delayed to April. Things are getting smoother, however, as the first units of the are rolling off the production line -- and there are already customers waiting at Seton Hall University. Keeping up its recent practice of handing out gadgets to junior students, the school expects to test the dockable Windows 8 tablet within a few weeks, and then deliver about 2,000 units to newcomers starting in June. The turn toward a hybrid lets the university settle on one PC design for the fall rather than divide its attention between tablets and Ultrabooks, Seton Hall's Drew Holden says. As for the general public? Lenovo hasn't officially put the Helix on sale through its own store, but a handful of customers say they've already received theirs through other channels. In any event, keep a close watch on third-party stores if you're willing to part with $1,499 for a ThinkPad convertible.
Carnegie Mellon's Chimp robot is reporting for duty, sir
See that guy? He's for real. He's also from Pittsburgh. A team of wizards from Carnegie Mellon University's National Robotics Engineering Center is presently building a new "human-scale" robot in order to compete in DARPA's Robotics Challenge. Part of its charm revolves around the rubberized tracks on its feet as well as on the extremities of each of its four limbs -- not surprisingly, these are engineered to help it maneuver in some pretty sticky situations. According to the institution, it'll move much link a tank, but it'll also be able to chug along on the treads of just two limbs when needed, such as when it must use one or more limbs to open a valve, or to operate power tools. Oh, and in case you're curious, CMU has affirmed that it'll "be able to perform complex, physically challenging tasks through supervised autonomy," which sounds precisely like the kind of vague description an ill-willed robot would explain to its master before completely taking over his / her life. Just sayin'.
Microsoft boosts SkyDrive with six month Office 365 University test drive, ad campaign
Office 365 University is already pretty cheap, but to get you hooked on the software while also promoting SkyDrive's collaboration tools, Microsoft's giving up to six months worth of free access to US college attendees. It's promoting the grab using Parks & Recreation's Aubrey Plaza, who shows a trio of students in one YouTube video (after the break) how they can work together using the Office 365 / SkyDrive combo while staying in their own "creepy dorm" and "unicorn stable" instead of bugging her. Takers will get an extra 20GB of SkyDrive storage and three months of access to the suite, which can be extended to six by sharing the offer on Facebook. If Microsoft decides to include Aubrey and her pithy putdowns in place of Clippy, we'd actually be okay with that, too.
What can WoW and other MMOs teach us about literature and storytelling?
While the world of academia has not infrequently pried back the edges of World of Warcraft to peer through its lens into fields including psychology, sociology and anthropology, and economics, we don't often hear reports from the intersection of WoW and literature. With a lore and canon of their own making, WoW and the Warcraft world don't fit alongside such developments as Online Games: Literature, New Media, and Narrative, a course from Vanderbilt University available via free online educational provider Coursera that leans heavily on the riches of narrative theory, intermediality, and game theory in Lord of the Rings Online. But there's no denying the omnipresence of WoW's influence -- and yes, that includes within the ivory-tooled tower of literature, as well. "I'm a literature professor," states Dr. Jay Clayton, one of the Coursera class's instructors. "I'm fascinated by what games can teach us about the operations of storytelling." Dr. Clayton says he's hoping to attract WoW players and their own WoW-tinged perspectives to his class this summer in order to help build a more complete picture of what WoW is itself as media, not only as a lens through which we can view other disciplines.
Universities to offer free online courses with credit, let us try before we learn
It's not really practical to give universities a meaningful test drive. Not without ample amounts of money and time to throw at a practice semester, at least. It's about to become comparatively trivial. Arizona State, the University of Cincinnati and 38 other institutions are teaming up with Academic Partnerships to offer the first course from certain online degrees for free -- and, more importantly, to make it count as credit. Money only matters to participants (and Academic Partnerships) if they move on to the full program. Prospective students will have to wait until the spring to sign up for what's ultimately a freemium education, but patience could be a virtue if it means understanding the workload before committing to what may be years of higher learning.

Access4Kids input device allows disabled children to control touch-centric tablets (video)
The innovation world at large has been crafting ways for handicapped individuals to interact with computers for years on end, but the issue of tablets has created another predicament entirely. How do you enable someone to masterfully control a touch-centric device, when the mere act of touching is a challenge? Ayanna Howard, professor of electrical and computer engineering at Georgia Tech, and graduate student Hae Won Park have created Access4Kids, which is described as a "wireless input device that uses a sensor system to translate physical movements into fine-motor gestures to control a tablet." In essence, it enables individuals with limited mobility to pinch and swipe, and the group has had success thus far with providing greater accessibility to flagship programs like Facebook and YouTube. Moreover, custom-built apps for therapy and science education are cropping up, with the existing prototype utilizing a trio of force-sensitive resistors that measure pressure and convert it into a signal that instructs the tablet. A child can wear the device around the forearm or place it on the arm of a wheelchair and hit the sensors or swipe across the sensors with his or her fist, providing an entirely new level of interaction for those with cerebral palsy, traumatic brain injury, spina bifida and muscular dystrophy. The goal? Once it's honed, to get it out of the lab and made "into a commercial product." Head on past the break for a video look.
Cambridge University starts Doomwatch unit, hires Skype co-founder to fight the future
Despite warnings to the contrary, Cyberdyne, SkyNet and Demon Seed are technological terrors that currently exist. No matter, as we've now got someone leading the fightback -- Skype co-founder Jaan Tallinn. He's part of a team of scientists, engineers and philosophers at Cambridge University's newly-minted Centre for the Study of Existential Risk. Aping the plot of beloved '70s TV series Doomwatch, the unit will investigate the fringes of science fact, including biotechnology, artificial intelligence and climate change. He'll be joined by Huw Price and Baron Martin Rees, who we hope will travel around the country in a minivan and fight ghosts, just like these guys.
Proportional VR experiment shrinks man down to rat size, lets us play games with rodents
Sure, you can always play catch with the dog, but what kind of game can you play with a caged rodent? Well, "find the poster," apparently. A team of researchers from Universities in Spain, Germany, Austria, England and the US have put together a virtual reality system designed to let humans interact with rats at the rodent's scale, challenging human participants to find and lead the rodent to a unmarked goal. According to a paper published in PLoS One participants were "beamed" into the rat's environment by linking a head-mounted display and joystick to a rat-sized telepresence robot. Human players were then treated to a proportionally accurate representation of the game arena. The rat was there too, tracked with an overhead camera and represented by a human avatar. Participants were tasked with coaxing their opponent in front one of three posters in attempt to sleuth out which one represents the "winning" position. When both players are in front of the correct mystery poster, a bell sounds and the game ends. The game was primarily created to test a scaled immersive virtual reality teleoperator system, but researchers are optimistic the technology could be used to observe animal behavior from a new perspective. Check out the setup in action after the break, or read on through to the source link below for a detailed description of how mankind and some of nature's smaller creatures can get along in a virtual space.
Rice University offers course on Old Norse mythology, Skyrim
Look, you don't need an expensive piece of paper from some institution to know that you're the Dohvakiin. You know it, we know it, the guy you yelled at until he died knows it -- that's all that really matters in the long run. But, if for some reason you did want to expand your knowledge of the ancient legends behind your ancient legend, Rice University has you covered."Scandinavian Fantasy Worlds: Old Norse Sagas and Skyrim" is a new course at Rice University in Houston, TX, which "introduces students to fantasy as both psychological concept and driving force in gamer culture" by having students "read selections from Old Norse and Old Icelandic sagas (in translation) as they play different quests within Skyrim."As you can imagine, enrollment availability is limited to actual, bona fide students at Rice University. Additionally, the class is only available this semester, which is sad considering that beating Skyrim will most likely take longer than passing the course.
Microsoft launches four-year, $80 Office 365 University subscription for students
Microsoft's given Xbox love to PC-buying students recently, and it's just announced that it'll carry on that tradition with Office 365 University, by offering a special four-year, $80 subscription to higher-education students. For that sum, you'll get four years of Word, PowerPoint, Excel, OneNote, Outlook, Publisher and Access if you're seeking a sheepskin scroll, which Redmond says works out to $1.67 per month. Also included are 60 Skype world minutes per month and 27GB of Premium SkyDrive storage, along with free upgrades and the ability to install on two separate computers, to boot. That should take some of the sting out of those scholarly expenses if you need a copy, so check the source to see how to grab it.

Researchers create record-breaking solar cell, set bar marginally higher
Solar cell development is typically a small numbers game, and a group of researchers at the University of Toronto have managed to eke out a few more percentage points in efficiency with a new record-breaking cell. Setting a high mark for this type of cell, the team's Colloidal Quantum Dot (CQD) film harvests both visible and non-visible light at seven percent efficiency, a 37 percent increase over the previous record. The breakthrough was achieved by leveraging organic and inorganic chemistry to make sure it had fewer nooks and crannies that don't absorb light. With the advantages of relatively speedy and cheap manufacturing, the technology could help lead the way for mass production of solar cells on flexible substrates. In the meantime, check out the source for the scientific lowdown.
