University Adds Twitter to Curriculum

Go to pretty much any college campus in the world, and you'll stumble upon Socrates, ponder over Plato, or fling a frisbee during a game of Ultimate. One university in Australia, though, is adding a dash of online social networking to their course catalog. Welcome to Twitter-damia.

In a move that further cements Twitter's status as a mainstream media tool, Griffith University has introduced a new mandatory Twitter course for its journalism students. The class aims to refine and sharpen young writers' tweets, which, according to senior lecturer Jacqui Ewart, "are not as in depth as you might like." University officials cited the growing journalistic role of Twitter in major world events like last summer's Iranian protests as the motivation behind the new course.

Clown on a Unicycle Goes Unnoticed by Cell Phone Users

Clown on a Unicycle Goes Unnoticed by Cell Phone Users
It's conventional wisdom at this point that cell phones are distracting, and that even simple activities like walking can become dangerous endeavors when mixed with texting. We've read, and reported on, study after study concerning cell phone users' lack of awareness, but the particulars of one such study, reported by LiveScience, stands out.

One part of the study, headed by Ira Hyman, Jr. of Western Washington University, involved interviewing 150 students who had just walked across the university's campus. He tried to ascertain whether or not the students had seen anything strange on their stroll. Hyman (Stop giggling... what are you, six?) was hoping the interviewees spotted one of his students who was dressed in a clown suit and riding a unicycle around a prominent sculpture on campus. When asked directly if they had seen such a clown, those who were speaking on the phone or text messaging were far less likely to have noticed the odd scene than were other participants.

College Courses on Twitter, 'Guitar Hero' -- Dumb or Smart Trend?



Media outlets love headlines like 'University Teaches Twitter 101' or 'Facebooking Now Part of Curriculum.' Usually, though, such claims of kids being taught to tweet are sensationalized. It is true, though, that schools are increasingly looking towards new media to study the way we communicate. Take for instance Chicago's DePaul University and its course on modern journalism. The class, titled 'Digital Editing: From Breaking News to Tweets,' isn't talking solely about Twitter, but about the changing landscape of news reporting.

Similarly, New York University is currently offering a course featuring 'Guitar Hero.' But don't assume students are learning how to rock using the plastic axes; Professor Gary Marcus is interested in how 'Guitar Hero' affects human cognition, telling NBC New York that "video games are an understudied area." Parents are nonplussed, reportedly irritated by the idea of shelling out $50,000 a year to see their kid do what he or she would do at home, anyway.

Students Create $20 Prosthetic Leg -- and It Works!


Now that the technology for advanced prosthetic limbs is achievable, students at Stanford University are trying to make it actually attainable for the average person around the globe.

Students in the school's Biomedical Device Design and Evaluation program started the JaipurKnee Project, and challenged themselves to create a fully-functioning prosthetic leg that could be manufactured for a very low price. Clearly, they were successful, creating the above, fully-functioning appendage for just $20 in parts and production costs.

In order to improve upon the sorts of limbs currently used in developing countries, the team first studied high-end titanium knee joints, which cost anywhere from $10,000 to $100,000. It then explored standard materials found in cheap prosthetics around the globe, and, eventually, came up with the design for a self-lubricating knee joint made from an oil-filled nylon polymer, significantly cutting production costs.

Will Podcasts Replace Professors?



A recent psychological study suggests that iPods and podcasts might be stealing some thunder from collegiate professors and lectures, we've learned from Ars Technica.

Psychologist at the State University of New York in Fredonia, Dani McKinney based the report, entitled "iTunes University and the classroom: Can podcasts replace Professors?", on a study of 64 students. After being encouraged to take notes during a psychology lecture that was supplemented by a PowerPoint presentation, the students were split into two groups. McKinney and her associates provided the first group with PowerPoint printouts while they gave a podcast of the lecture, synchronized with the PowerPoint slides, to the second group.

When the students took a test on the subject material one week later, the podcast-supplied students wound up better off, with an average score of 71, while the PowerPoint slide-equipped students averaged a 62.

While these findings do demonstrate the benefits of using podcasts as study aides, we are -- truth be told -- far from foretelling the obsolescence of professors. Need proof? The highest-scoring group of students, averaging a grade of 77, were those who listened to the podcast and took notes during lecture. [From: Ars Technica]

Geolocator-equipped Backpacks to Track Bird Migrations


We've seen birds tasked with carrying around sensors in order to provide data about external happenings, but up until now, tracking birds' migration patterns from start to finish has been a tedious, if not impossible task. Gurus from York University in Toronto have apparently figured out the solution, and it all sounds much simpler than you might imagine. By equipping birds with minuscule "backpacks" -- which weigh less than a dime and use geolocators to collect all sorts of information about flight times, patterns, stopovers and speed -- scientists can get an accurate look at where the animals were and when they were there. In a recent test involving 34 birds, researchers were able to retrieve the packs from 7, and while that may not be a majority, biologist J. M. Stutchbury noted that this "was 7 more than anybody else." Right you are, Doc. [Via New York Times, image courtesy of PaulNoll]

Sensor-laden Footballs and Gloves Could Run Refs Out of Work


Dr. Priya Narasimhan, a professor at Carnegie Mellon University, doesn't intend to put a single NFL referee out of work, but there's no doubt that the technology she's tinkering with could indeed have that effect. The prof and her students are developing sensor-laden footballs and gloves, both of which could eventually tell in real-time whether a ball bounced off the ground before being caught or whether a player actually had possession of a ball whilst being piled upon after a fumble. Currently, she's had zero luck persuading a college or professional team to help her experiment further, and we can sort of see why. We mean, it's nice to get every call right in theory, but what fun would sport be without the all-important "Ref, you suck!" chant?

In-car Fingerprint Scanner Keeps Drunks, Thieves From Starting Your Car

How's this for dual purpose? Zhao Wencai and Li Zhoumu, two graduate students at the China University of Geosciences, have concocted a prototype device which checks for two important bits of information before allowing a car to start. First, it scans your fingerprint to make sure you're on the authorized driver database; second, it takes a long, hard look (okay, so maybe 20 seconds isn't all that long) at the sweat on your digit to determine just how sober or inebriated you are. There's no telling when this will hit motorcars en masse, but we'd say the whole thing needs to get a whole lot smaller before it's a viable option. [Via Wired]

Key Jams Cellphones, Ends Texting/Talking While Driving


Face it, kids. You missed the best time to be a teenager by around five or so years. As it stands now, technology is cutting into that adolescent fun, with device like Ford's MyKey and this one here ensuring that you're actually safe behind the wheel. In all seriousness, the terribly named Key2SafeDriving is a fine concept (at least in the parent's eye), as it fuses a cellphone jammer (of sorts) into a key fob in order to put the kibosh on freeway conversations. Essentially, the signal blocking kicks into action anytime the "key" portion is flicked out, connecting to a handset via Bluetooth or RFID and forcing it into "driving mode." No actual jamming, per se, is going on; it's more like a manual override of the ringer. Anyone who phones / texts you while you're safely driving will receive an automated response informing them of such, though we are told that handsfree devices can be utilized. Researchers at the University of Utah are hoping to see it on the market within six months via a private company "at a cost of less than $50 per key plus a yet-undetermined monthly service fee."

Digitally Assisted Billiards Makes Everyone a Pool Shark


There's cheating, and then there's out-thinking the room. Georgia Tech's own Justin Needham and Matthew Straub are clearly headed for great things, as their Digitally Assisted Billiards is reason enough to give these guys a degree in our eyes. Using an array of low-end kit -- just an eBox 2300 embedded computer, Logitech webcam, 4- x 3-foot mirror, a VGA projector, pool table and a few extenders -- the two were able to concoct a system for visually displaying the expected trajectory of all possible shots based on the location of the balls still on the slate. For a much better idea of what we're hinting at, check the demonstration video after the break. [Via Hack-A-Day]

HP and ASU Show Off Bendable, Unbreakable Electronic Displays

,
Well, what do you know? Nearly four years after Arizona State University opened its very own flexible display center comes this, a prototype device that's purportedly easy to manufacture, easy on the environment and practically as strong as Thor. HP and ASU have teamed up to demonstrate the fresh e-displays, which are constructed almost entirely of plastic and consume far less power than traditional computer monitors. The "unbreakable displays" were crafted using self-aligned imprint lithography (SAIL) technology invented in HP Labs, and while we'd love to see this in a pliable laptop at CES 2009, we suspect it'll be a few years yet before these slither out to the commercial realm.

Startup Develops iPhone Apps for Universities

Startup Develops iPhone Apps for Universities
We'd estimate that 99.9 percent of the programs in the App Store are little more than a waste of time. So we get excited when a developer starts showing off tools for the iPhone and iPod touch that look genuinely useful.

A small startup, called TerriblyClever, is testing out a suite of applications aimed at universities that, if it becomes widespread, might make the Apple handhelds an indisposable tool for college students. The app is being given a trial run at Stanford University and is appropriately (and unoriginally) called iStanford. It consists of five tools that allow students to add and drop classes, plan a schedule, pay bills, look up contact info in the school directory, find locations on a campus map, and get up-to-date scores from school sports teams.

TerriblyClever hopes to expand its list of client schools and its suite of apps over the ensuing months. This could also be a great delivery method for news about class cancellations and campus alerts. Much better than the text message based CUNY (City University of New York) system which sends out useless messages like:
"FRM:NY-Alert Administrator
SUBJ:NY-Alert
MSG:CUNY Alert:College of Staten Island aΔ"
(that is not a typo)

SecuriScan Shoe Scanner Could Make Airport Lines Shorter

Huge shocker here: removing your shoes at airport security causes massive headaches and makes the wait longer for everyone. Now that we're all good with Captain Obvious' latest headline, let us point you to one prototype that's looking to solve said dilemma. SecuriScan, which has been developed by Professor Wuqiang Yang at the University of Manchester, would theoretically be able to "detect and pinpoint suspicious objects instantly," all without requiring passengers to remove their kicks.

Better still, the system uses electric and magnetic sensing instead of a radiation source, which could also address safety concerns while helping you get where you're going more quickly.

Moving forward, Yang hopes to develop a more advanced and realistic prototype for testing, and just in case you were doubting this guy's determination, he's also investigating a handheld version that could hastily screen abandoned luggage or packages.

Researchers Advance Remote Monitoring Systems for the Elderly


Assistive technologies are old hat, but a team of researchers at the University of Texas at Arlington (among other institutions) is working to provide a more robust, all-inclusive option for elderly individuals who'd prefer to age gracefully within their own domiciles. In theory, sensors could be embedded throughout seniors' homes in order to "detect when the residents have sleepless nights or forget to take their medication." From there, caregivers would be alerted and could react remotely via a web-based communications portal. The UTA lab that's perfecting the idea currently utilizes a single room equipped with cameras, motion detectors and robots, and professors / students keep a close eye on any movement that gets recorded and transferring to computers for processing. If all goes well, a collaboratively built "home of the future" will actually be on display at CES 2009, likely showcasing some of these very advancements.

Researchers Unveil 'Unbreakable Encryption'

Call us devilish, but we just can't help but love these types of stories. Here we have yet another overly confident group of researchers grossly underestimating the collective power of the hacking underground, as gurus from all across Europe have joined together to announce "the first commercial communication network using unbreakable encryption based on quantum cryptography."

Interestingly enough, quantum cryptography has already been cracked in a kinda-sorta way, but that's not stopping these folks from pushing this claim hard to government agencies, financial institutions and companies with distributed subsidiaries.

We've no doubt this stuff is pretty secure, but the last time we heard someone utter a claim similar to this, we saw him uncomfortably chowing down on those very words merely months later.
