Exploit uses firewalls to hijack smartphones, turns friends into foes
Normally, firewalls at cellular carriers are your best friends, screening out malware before it ever touches your phone. University of Michigan computer science researchers have found that those first lines of defense could be your enemy through a new exploit. As long as a small piece of malware sits on a device, that handset can infer TCP data packet sequence numbers coming from the firewall and hijack a phone's internet traffic with phishing sites, fake messages or other rogue code. The trick works on at least 48 carriers that use firewalls from Check Point, Cisco, Juniper and other networking heavy hitters -- AT&T being one of those providers. Carriers can turn the sequences off, although there are consequences to that as well. The only surefire solution is to either run antivirus apps if you're on a mobile OS like Android or else to run a platform that doesn't allow running unsigned apps at all, like iOS or Windows Phone. Whether or not the exploit is a serious threat is still far from certain, but we'll get a better sense of the risk on May 22nd, when Z. Morley Mao and Zhiyun Qian step up to the podium at an IEEE security symposium and deliver their findings.
Texting: the truth serum of the 21st century
The University of Michigan and The New School for Social Research has found that if you want someone to tell you the truth, you should text them. Dispensing with the lie detector for job interviewees, academics found that people gave more honest and detailed answers via SMS than over the phone. The team believes it's due to the lack of time pressure and not having to produce a pleasing answer for your interrogator. If the findings continue to provide similar results, it looks like Steve Wilkos could be replaced with a smartphone.
Caltech sets 186Gbps Internet speed record, makes our 5Mbps look even more inadequate (video)
Did you know that the Large Hadron Collider at CERN has already produced 100 petabytes of data that needed to be sent out to labs across the world for analysis? Pushing that amount of information across the Internet is a gargantuan task, which is why Caltech teamed up with the Universities of Victoria, Michigan and Florida (International) amongst others to try and break the internet speed record. Using commercially available gear (including Dell servers with SSDs), it was able to push 98Gbps and pull 88Gbps down a single 100Gbps fibre-optic connection between the Washington State convention center in Seattle and the University of Victoria computing center in British Columbia. Head on past the break for a video that shows you how it was done and why it probably won't be commercially available in time to super-size your Netflix queue.
New 'subconscious mode' could improve smartphone battery life, supress your WiFi id
Researchers at the University of Michigan have figured out a way to drastically increase your cellphone's battery life, at least while using WiFi. By using what they're calling E-MiLi, or Energy-Minimizing Idle Listening, professor Kang Shin (right) and student Xinyu Zhang have developed a proof of concept that could extend battery life up to 54-percent with the WiFi radio on. Even when idle, a wireless radio is actively checking for incoming traffic. E-MiLi scales back the wireless card's clock to just 1/16th of its normal operating speed, and only kicks back into full gear when it senses incoming data. To be really useful though, we'd love to see the same trick employed on cellular data networks -- that LTE sure is fast, but it's not exactly battery-friendly. Check out the PR after the break.
DARPA harvests energy from cyborg beetles to keep them brainwashed
Beetles packing cybernetic implants that control their brains make a cheaper and more useful micro-air-vehicle than a fully robotic one -- but due to the weight of the battery packs required, development has been slow. Now a DARPA-funded team at the University of Michigan thinks it's eliminated that problem. By attaching piezoelectric generators to each wing, the researchers can harvest the energy generated in flight and use it to juice the mind-control circuits. At present, the system generates about half the energy the team thinks it can produce, as innovations in ceramic production of the miniature devices should solve that. An experimental robotics project in competition with a cyborg one? This all feels a bit too RoboCop for us.
MABEL running robot snags bipedal speed title, cue 'Rocky' theme (video)
MABEL the running robot has been training hard, grabbing the title of "fastest bipedal robot with knees." Like any great sports star, it's been plagued by many dream-crushing obstacles and injuries, but this time it's done it: running at a speed of 6.8 miles per hour on a track. Jessy Grizzle, professor at the University of Michigan's Department of Electrical Engineering and Computer Science, attributes this bot's success to its human-like weight distribution -- a heavier torso and flexible legs with springs similar to tendons for movement "like a real runner." This bipedal technology, which can mimic a human's ability to run and climb over obstacles, may be used to help the disabled walk again, in rescue situations or as the basis of future vehicles that don't require roads or wheels to drive. If MABEL doesn't make the SWAT team this year, it can most certainly snag a spot as an extra in the next Transformers movie. Check out the PR and video of this modern day robo-Flo-Jo after the break.
Telex anti-censorship system promises to leap over firewalls without getting burned
Human rights activists and free speech advocates have every reason to worry about the future of an open and uncensored internet, but researchers from the University of Michigan and the University of Waterloo have come up with a new tool that may help put their fears to rest. Their system, called Telex, proposes to circumvent government censors by using some clever cryptographic techniques. Unlike similar schemes, which typically require users to deploy secret IP addresses and encryption keys, Telex would only ask that they download a piece of software. With the program onboard, users in firewalled countries would then be able to visit blacklisted sites by establishing a decoy connection to any unblocked address. The software would automatically recognize this connection as a Telex request and tag it with a secret code visible only to participating ISPs, which could then divert these requests to banned sites. By essentially creating a proxy server without an IP address, the concept could make verboten connections more difficult to trace, but it would still rely upon the cooperation of many ISPs stationed outside the country in question -- which could pose a significant obstacle to its realization. At this point, Telex is still in a proof-of-concept phase, but you can find out more in the full press release, after the break.
BioBolt brain implant could help the paralyzed walk again
Controlling a cursor with your brain? Yawn. Restoring movement to paralyzed mice? Color us unimpressed. Help a wheelchair-bound man walk again using only his thoughts? Now we're talking. That's the goal of researchers at the University of Michigan who have developed BioBolt, a (comparatively) noninvasive implant that rests on top of the cortex rather than penetrate it. The device is inserted through an easily-covered, dime-sized hole in the skull and feeds patterns from firing neurons to a computer using your epidermis (which is showing, by the way) as a conductor. The ultimate goal of helping the paralyzed walk again is still years away but, in the meantime, it could be used to suppress seizures or diagnose diseases like Parkinson's. Everyday this mind over matter thing sounds a little less like a load of bullpuckey.
Newly discovered properties of light promise better solar batteries, really great tans
Are you tired of waking up to the same old semiconductor-based solar array? Do you yearn for a change? We know you do and, thanks again to the wonder and mystery of magnetic fields (they're not just for stopping speech anymore), there's a new day dawning. University of Michigan scientists were shooting lasers at glass, as they do, and made a remarkable discovery: light passing through a non-conductive surface like glass generates impressive magnetic effects – up to 100 million times greater than expected. The resulting magnetic force could replace the electric effect exploited by current technology, paving the way for "optical batteries." Though different from the Wysips transparent photovoltaic cell, the technology could have similar applications and may render obsolete those massive solar farms. No need to worry, though -- your stylish solar backpack is as fly as it ever was.
FBI raids University of Michigan apartment over possible WoW fraud
A University of Michigan student apartment became the focus of a recent investigation by the FBI, which conducted a raid on March 30th over "potentially fraudulent sales or purchases of virtual currency that people use to advance in the popular online role-playing game World of Warcraft." While the FBI did not make any arrests, it did confiscate several items, including computers, video game equipment, and credit cards. The Bureau is checking out whether one or both of the students were involved in a fraudulent scheme to buy or sell virtual gold, and the agency is looking for online transaction records with various online banks and websites. The two students who share the apartment claim that they do not play WoW and are confident that they are innocent. One of the unnamed students commented: "They thought we were involved in some kind of fraud. I'm pretty sure they have the wrong people, but they took all my stuff."
Scientists improve blue OLED efficiency, don't promise everlasting light
Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.
Researchers debut one-cubic-millimeter computer, want to stick it in your eye
This as-of-yet-unnamed mini computer was fashioned as an implantable eye pressure monitor for glaucoma patients, but its creators envision a future where we're all crawling with the little buggers. Taking up just over one cubic millimeter of space, the thing stuffs a pressure sensor, memory, thin-film battery, solar cell, wireless radio, and low-power microprocessor all into one very small translucent container. The processor behind this little guy uses an "extreme" sleep mode to keep it napping at 15-minute intervals and sucking up 5.3 nanowatts while awake, and its battery runs off 10 hours of indoor light or one and a half hours of sun beams. Using the sensor to measure eye pressure and the radio to communicate with an external reader, the system will continuously track the progress of glaucoma, without those pesky contacts. Of course, the mad scientists behind it look forward to a day when the tiny device will do much more, with each of us toting hundreds of the computer implants all over our bodies -- looks like a bright future for cyborgdom.
UM students make cheap and portable solar charger / light source for developing nations
Solar power is the most egalitarian of all energy sources, yet residents in many parts of the world still lack access to electricity. Three University of Michigan engineering students have created an affordable solution to this problem -- to the delight of camping geeks everywhere -- with the Emerald, a portable solar panel that does double duty as both a cellphone charger and personal light source. We've seen the personal solar panel idea before, but the price of entry made it an untenable solution for developing nations. Solar-powered light bulbs have been around for a while too, but the Emerald's light lasts for eight hours on a charge (as opposed to the bulbs' two to six hours), and it's able to fully charge a phone in the same time it takes an outlet to do the job. They aim to sell the device for the low, low, price of under twenty bucks for customers in the developing world, which is 90 percent cheaper than other solutions and 100 percent more awesome.
Audi commissions four US universities to research urban mobility issues
We've seen what other companies have in store for our automotive future, and now Audi's given us a glimpse of what we can expect from its car of tomorrow. The company's Silicon Valley research lab has teamed up with four universities here in the US to develop technologies that will give city drivers the full KITT treatment -- vehicles that recognize the driver (and his or her preferences) and can detect and avoid dangers and traffic delays. Called the Audi Urban Intelligence Assist initiative, each participating university has a specific area of urban mobility research ranging from urban crash analysis to aggregating historical and real-time traffic, parking, and pedestrian data in cities. The schools will also study how best to deliver relevant information to drivers and get them from point A to point B as easily and efficiently as possible. Looks like the groundwork is being laid for a German counterpart to GM's EN-V we test drove in Vegas, and we look forward to the fruits of their labor. Ich bin ein Ingolstädter!
iPhone headset socket hijacked to power DIY peripherals (video)
Apple's proprietary dock connector may keep would-be peripheral manufacturers at bay, but if you want to build your own iOS companion devices, there's another way. You might have noticed that the Square credit card reader uses Apple's 3.5mm headset jack to transmit power and data at once, and gadgeteers at the University of Michigan are busy open-sourcing the same technique for all the DIY contraptions you can dream of. Project HiJack has already figured out how to pull 7.4 milliwatts out of a 22kHz audio tone, and built a series of prototype boards (including working EKG, temperature, humidity and motion sensors) that transmit data to and from an iOS app at up to 8.82 kbaud -- using just $2.34 worth of electronic components. See the basic principles at work in the video above, and -- as soon as the team updates Google Code -- find out how to build your own at the links below.
DC election website hacked, John Philip Sousa pleased
Unlike the secrecy that usually surrounds e-voting efforts, the folks at the Washington D.C. Board of Elections and Ethics had a novel approach: Why not invite hacksters of all stripes and temperaments to bust into the new online system being tested for overseas and military voters? Of course, it was only a matter of time before a security hole was discovered -- and now we know that the University of Michigan fight song is called The Victors. It seems that a certain college professor unleashed his students on the site, at which point they quickly sniffed a way in and left an MP3 of the tune ("the greatest college fight song ever written," according to John Philip Sousa) as their calling card. The board has made the source code and server info available (the better to test its mettle) and we must say, it's certainly good to see public officials paying more than lip service to security -- especially where electronic voting is concerned. The site was down over the weekend, and is back up now, but with one crucial difference: ballots will have to be mailed, faxed, or e-mailed in.
U of M laser mimics helicopter heat signatures to thwart missiles
Researchers at the University of Michigan have developed a new laser-based countermeasure for aircraft, and unlike others we've seen (and we've seen a few) this technology aims to "blind" missiles rather than knock 'em out of the sky. The system uses a mid-infrared supercontinuum laser to mimic the heat signature of a helicopter, and it has no moving parts -- making it rugged enough to last a long time on rotor-based aircraft. The school has even spun off a company, Omni Sciences, to develop the thing, and has received some $1 million in grants from the Army and DARPA to build a second-generation prototype. Of course, questions remain: is it really a wargadget if you can't blow something up with it? And even if it is, where's the fun in that?
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?
Nanotechnology enables ultra high-def LCDs, cheaper stacked-electrode OLED screens
Pixel density enthusiasts, pay close attention, because science is ready to blow your minds -- the University of Michigan has developed an LCD technology that can display their logo in a space just nine microns high. By creating a filter made of microscopic metal gratings with differently sized holes just a few hundred nanometers wide, researchers discovered they could precisely capture wavelengths associated to red, green and blue light, producing pixels roughly eight times smaller than those in the iPhone 4's famous screen, and entire images that could practically fit inside a single dot of Kopin's microdisplay. Meanwhile, OLEDs (which don't require filters to produce their color) saw a nanotech breakthrough of their own last week, as a group at the University of Florida have discovered that carbon nanotubes can revitalize a once-inefficient but promising vertical stacking technique. Layering thin sheets of aluminum, carbon nanotubes, organic material and finally gold on top of a glass substrate, scientists have created OLEDs that promise to be cheaper, faster and require one-tenth of the power of those using polycrystalline silicon, and could theoretically be printed as a flexible display as well. Here's hoping we'll see the fruits of these fellows' labors soon -- we can't wait to pen a follow-up to this epic fight.
Sequoia e-voting machine hacked to play Pac-Man (video)
Oh Sequoia, why are you so changeable? The thoroughly hacked electronic voting machine is back with another ignoble showing, courtesy of researchers from the universities of Michigan and, of course, Princeton. Picking up an AVC-Edge box that had seen live duty in collecting votes for the 2008 Virginia primaries, they quickly and all too easily managed to supplant the embedded psOS+ software with DOS, which was promptly followed by the installation of Pac-Man. Given that the underlying circuit boards were populated with such luminaries as a 486 processor and 32 megabytes of RAM, we find this a most appropriate match of hardware and software. As to that whole voting security thing, maybe next time we should let people do it with their BlackBerrys, eh? See the Pac do his thing on video after the break.
