Hackers Can Use Smart Watch Movements To Reveal A Wearer's ATM PIN (ieee.org)
the_newsbeagle writes: By gaining access to the sensors in someone's smart watch, hackers could track the person's hand movements at an ATM and figure out his/her pin. The hacker needn't be anywhere near the ATM; data can be lifted from the smart watch by either a discreet wireless sniffer or by malware on the watch that sends info to a server. This is hardly the first demonstration of the security flaws in smart watches. Last year, a research group showed that a watch's sensors can reveal keystrokes on a computer keyboard. The team of researchers, led by Chen Wang and Yingying Chen at the Stevens Institute of Technology in Hoboken, New Jersey, were able to record movements down to the millimeter and crack private ATM PINs with 80 percent accuracy on the first try. To eliminate the security breach, manufacturers could better secure the data stored in their wearables, and/or add noise so one's physical hand movements cannot be as easily translated. Of course, consumers could simply wear their smart watch on their non-dominant hand. -
Researchers Turn Smartphone Vibration Motor Into Microphone To Spy On You (softpedia.com)
An anonymous reader writes from a report via Softpedia: Two researchers from the University of Illinois at Urbana-Champaign have come up with a method to turn smartphone vibration motors into makeshift microphones, capable of recording the sound around them. The attack relies on using the vibration motor's coil to record incoming sound waves, which are then transmitted to the attacker, who then uses a processing algorithm to enhance the signal by reconstructing high-frequency waves. This is needed because the vibra-motor can only pick up low-frequency sounds, up to 2 kHz. Their method doesn't yield perfect results (4 in 5 people can understand the sounds) and also needs physical access to the device, but it puts in place the theoretical details needed to carry out and refine such attacks in the future. -
Researchers Use Smartwatch To Spy What Users Are Typing On a Keyboard
An anonymous reader writes: Researchers have created an app that follows the micro-movements of your smartwatch and is able to detect what keys you're pressing with your left hand, and guess what words you may be typing on a keyboard. The app developed for the Motion Leaks (MoLe) project only works on a Samsung Gear Live smartwatch, but researchers say that in theory, a similar app could be developed for other smartwatch makes and models. -
University Students Made a Working Model Hyperloop
derekmead writes: Elon Musk's Hyperloop gets people excited. Promise the ability to travel from San Francisco to Los Angeles in less than an hour, and you're going to get people salivating. But for as much as we've heard about it, we've had scarcely little to see—until a team of students at the University of Illinois decided to build their very own miniature hyperloop.
Mechanical engineering students at the university built a functioning 1:24 scale model of the Hyperloop, a "fourth mode of transportation" that sends pods through a partially pressurized tube at very high speeds, as part of a senior design project. It was designed to test some of the key components of Musk's design, which was outlined in a much-read, open source whitepaper (PDF) published in August of 2013. That said, there are several key differences, which keep this from truly being a proof-of-concept as to whether or not the Hyperloop will ultimately work. -
Low-Cost 3D-Printed Prosthetic Hand To Be Tested On Amputees In Ecuador
Zothecula writes A PhD candidate and six undergraduate students at the University of Illinois at Urbana-Champaign (UCIC) have created a low-cost, programmable, 3D-printed prosthetic hand that may soon change the lives of amputees in Ecuador. The hand costs just $270 to manufacture, making it a small fraction of the cost of a typical prosthetic of this type. -

How English Beat German As the Language of Science
HughPickens.com writes German was the dominant scientific language in 1900. Today if a scientist is going to coin a new term, it's most likely in English. And if they are going to publish a new discovery, it is most definitely in English. Look no further than the Nobel Prize awarded for physiology and medicine to Norwegian couple May-Britt and Edvard Moser. Their research was written and published in English. How did English come to dominate German in the realm of science? BBC reports that the major shock to the system was World War One, which had two major impacts. According to Gordin, after World War One, Belgian, French and British scientists organized a boycott of scientists from Germany and Austria. They were blocked from conferences and weren't able to publish in Western European journals. "Increasingly, you have two scientific communities, one German, which functions in the defeated [Central Powers] of Germany and Austria, and another that functions in Western Europe, which is mostly English and French," says Gordin.
The second effect of World War One took place in the US. Starting in 1917 when the US entered the war, there was a wave of anti-German hysteria that swept the country. In Ohio, Wisconsin and Minnesota there were many, many German speakers. World War One changed all that. "German is criminalized in 23 states. You're not allowed to speak it in public, you're not allowed to use it in the radio, you're not allowed to teach it to a child under the age of 10," says Gordin. The Supreme Court overturned those anti-German laws in 1923, but for years they were the law of the land. What that effectively did, according to Gordin, was decimate foreign language learning in the US resulting in a generation of future scientists who came of age with limited exposure to foreign languages. That was also the moment, according to Gordin, when the American scientific establishment started to take over dominance in the world. "The story of the 20th Century is not so much the rise of English as the serial collapse of German as the up-and-coming language of scientific communication," concludes Gordin. -
Brown Dog: a Search Engine For the Other 99 Percent (of Data)
aarondubrow writes: We've all experienced the frustration of trying to access information on websites, only to find that the data is trapped in outdated, difficult-to-read file formats and that metadata — the critical data about the data, such as when and how and by whom it was produced — is nonexistent. Led by Kenton McHenry, a team at the National Center for Supercomputing Applications is working to change that. Recipients in 2013 of a $10 million, five-year award from the National Science Foundation, the team is developing software that allows researchers to manage and make sense of vast amounts of digital scientific data that is currently trapped in outdated file formats. The NCSA team recently demonstrated two publicly-available services to make the contents of uncurated data collections accessible. -
Researchers Create Walking, Muscle-Powered Biobots
Zothecula writes If you're going to deploy robots in biological settings – for example, inside the body – it makes a lot of sense to build those robots out of actual biological body parts. Muscle, for example, is a very effective, biodegradable replacement for an electric actuator that can run in a nutrient-rich fluid without the need for any other power source. Bio-robotics experts in Illinois have demonstrated a bio-bot built from 3-D printed hydrogel and spinal muscle tissue that can "walk" in response to an electrical signal. Their next step will be trying to incorporate neurons that can get the bot walking in different directions when faced with different stimuli. -
Ask Slashdot: A 'Mavis Beacon' For Teaching Smartphone and Tablet Typing?
theodp writes: "Where have you gone, Mavis Beacon? A nation of smartphone and tablet typists could use your help. You've seen people type fast-and-furiously on smartphones and tablets, so you know it can be done, but how exactly do these one- and two-fingered wonders (YouTube video) manage to do so? Is it their reaction time? Technique? Both? Back in the day, touch-typing teachers showed kids the secrets to higher word-per-minute scores on their Smith Coronas. Later, typing tutor software got kids up-to-speed on PCs. So, with over 1 billion smartphones and 200 million or so tablets shipped in 2013, what are the best software and tutorials that teach mobile typing techniques? And what platform specific features — iOS, Android, WP8/Win8, BB — do you find make your mobile typing life a whole lot easier?" -
Researchers Report Super-Powered Battery Breakthrough
another random user writes with news that researchers from the University of Illinois at Urbana-Champaign are reporting a breakthrough in battery technology. They say: "With currently available power sources, users have had to choose between power and energy. For applications that need a lot of power, like broadcasting a radio signal over a long distance, capacitors can release energy very quickly but can only store a small amount. For applications that need a lot of energy, like playing a radio for a long time, fuel cells and batteries can hold a lot of energy but release it or recharge slowly. ... The new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale (abstract). The batteries owe their high performance to their internal three-dimensional microstructure. Batteries have two key components: the anode (minus side) and cathode (plus side). Building on a novel fast-charging cathode design by materials science and engineering professor Paul Braun’s group, King and Pikul developed a matching anode and then developed a new way to integrate the two components at the microscale to make a complete battery with superior performance. With so much power, the batteries could enable sensors or radio signals that broadcast 30 times farther, or devices 30 times smaller. The batteries are rechargeable and can charge 1,000 times faster than competing technologies – imagine juicing up a credit-card-thin phone in less than a second. In addition to consumer electronics, medical devices, lasers, sensors and other applications could see leaps forward in technology with such power sources available." -
'Blue Waters' Supercomputer Lucky To Exist
Nerval's Lobster writes "One could argue that the University of Illinois' "Blue Waters" supercomputer, scheduled to officially open for business March 28, is lucky to be alive. The 11.6 petaflop supercomputer, commissioned by the University and the National Science Foundation (NSF), will rank in the upper echelon of the world's fastest machines—its compute power would place it third on the current list, just above Japan's K Computer. However, the system will not be submitted to the TOP500 list because of concerns with the way the list is calculated, officials said. University officials and the NSF are lucky to have a machine at all. That's due in part to IBM, which reportedly backed out of the contract when the company determined that it couldn't make a profit. The university then turned to Cray, which would have had to replace what was presumably a POWER or Xeon installation with the current mix of AMD CPUs and Nvidia GPU coprocessors. Allen Blatecky, director of NSF's Division of Advanced Cyberinfrastructure, told Fox that pulling the plug was a 'real possibility.' And Cray itself had to work to find the parts necessary for the supercomputer to begin at least trial operations in the fall of 2012." -
5000 fps Camera Reveals the Physics of Baseball
concealment sends this quote from an article at The Physics of Baseball "This clip from Game 4 shows Marco Scutaro hitting the ball right near the tip of the barrel. The amplitude of the resulting vibration is so large that the bat breaks and the ball weakly dribbles off the bat. Note that the bat splinters toward the pitcher. The reason is that when the ball hits the barrel tip, the barrel of the bat bends backward toward the catcher and the center of the bat bulges forward toward the pitcher. That is the natural shape of the fundamental vibrational mode of the bat. Since the fracture occurs near the center which is bulging outward, that is how the bat splinters, as the wood fibers on the pitcher side of the bat are stretched to the breaking point. If the ball had impacted the bat near the center, the center would have bulged toward the catcher, as in the Yadier Molina clip. Had the vibrational amplitude been strong enough in the Molina case, the bat would have splintered toward the catcher." -
Illinois Prof Calls for a Federal Law To Safeguard Digital Afterlives
An anonymous reader writes "A new paper from Professor Jason Mazzone at the University of Illinois calls for federal laws to regulate what happens to digital accounts after the account holder's death. Mazzone argues that Facebook and other online services have policies for deceased users' accounts that do not adequately protect the individual property and privacy interests at stake. The full text of the paper (called "Facebook's Afterlife") is also available: " -
Poll-Based System Predicts U.S. Election Results For President, Senate
An anonymous reader writes "Election Analytics is a website developed by Dr. Sheldon Jacobson at the University of Illinois designed to predict the outcomes of the U.S. presidential and senatorial elections, based on reported polling data. From the site: 'The mathematical model employs Bayesian estimators that use available state poll results (at present, this is being taken from Rasmussen, Survey USA, and Quinnipiac, among others) to determine the probability that each presidential candidate will win each of the states (or the probability that each political party will win the Senate race in each state). These state-by-state probabilities are then used in a dynamic programming algorithm to determine a probability distribution for the number of Electoral College votes that each candidate will win in the 2012 presidential election. In the case of the Senate races, the individual state probabilities are used to determine the number of seats that each party will control.'" You can tweak the site by selecting a skew toward the Republican or Democratic tickets, and whether it's mild or strong. Right now, this tool shows the odds favor another four years for Obama, even with a strong swing for the Republicans. -

Intelligence Map Made From Brain Injury Data
An anonymous reader writes with this news out of the University of Illinois: "Scientists report that they have mapped the physical architecture of intelligence in the brain. Theirs is one of the largest and most comprehensive analyses so far of the brain structures vital to general intelligence and to specific aspects of intellectual functioning, such as verbal comprehension and working memory. Their study, published in Brain: A Journal of Neurology (abstract), is unique in that it enlisted an extraordinary pool of volunteer participants: 182 Vietnam veterans with highly localized brain damage from penetrating head injuries. ... The researchers took CT scans of the participants’ brains and administered an extensive battery of cognitive tests. They pooled the CT data to produce a collective map of the cortex, which they divided into more than 3,000 three-dimensional units called voxels. By analyzing multiple patients with damage to a particular voxel or cluster of voxels and comparing their cognitive abilities with those of patients in whom the same structures were intact, the researchers were able to identify brain regions essential to specific cognitive functions, and those structures that contribute significantly to intelligence." -
Installation of Blue Waters Petaflop Supercomputer Begins
An anonymous reader writes "The National Center for Supercomputing Applications at the University of Illinois is finally getting the troubled Blue Waters supercomputer installed. After IBM walked away from the project after 3 years of planning, Cray stepped in to pick up the $188 million contract. Now, in around 9 months time, Blue Waters should be fully operational and achieve performance of 1 petaflop or more. As for the hardware... who wouldn't want access to 235 Cray XE6 cabinets using AMD 16 core Opteron 2600 processors with access to 1.5 petabytes of memory (4GB per chip) and 500 petabytes of local storage." -
Liquid Metal Capsules Used To Make Self-Healing Electronics
MrSeb writes "A crack team of engineers at the University of Illinois has developed an electronic circuit that autonomously self-heals when its metal wires are broken. This self-healing system restores conductivity within 'mere microseconds,' which is apparently fast enough that operation can continue without interruption. The self-healing mechanism is delightfully simple: The engineers place a bunch of 10-micron (0.01mm) microcapsules along the length of a circuit. The microcapsules are full of liquid metal, a gallium-indium alloy, and if the circuit underneath cracks, so do the microcapsules (90% of the time, anyway — the tech isn't perfect yet!). The liquid metal oozes into the circuit board, restoring up to 99% conductivity, and everything continues as normal. This even works with multi-layer printed circuit boards (PCBs), such the motherboard in your computer, too. There's no word on whether this same technology could one day be used by Terminators to self-heal shotgun blasts to the face, but it certainly sounds quite similar. The immediate use-cases are in extreme environments (aerospace), and batteries (which can't be taken apart to fix), but long term we might one day buy motherboards with these self-healing microcapsules built in." -
Cray Replaces IBM To Build $188M Supercomputer
wiredmikey writes "Supercomputer maker Cray today said that the University of Illinois' National Center for Supercomputing Applications (NCSA) awarded the company a contract to build a supercomputer for the National Science Foundation's Blue Waters project. The supercomputer will be powered by new 16-core AMD Opteron 6200 Series processors (formerly code-named 'Interlagos') a next-generation GPU from NVIDIA, called 'Kepler,' and a new integrated storage solution from Cray. IBM was originally selected to build the supercomputer in 2007, but terminated the contract in August 2011, saying the project was more complex and required significantly increased financial and technical support beyond its original expectations. Once fully deployed, the system is expected to have a sustained performance of more than one petaflops on demanding scientific applications." -
NCSA and IBM Part Ways Over Blue Waters
An anonymous reader writes "IBM has terminated its contract with NCSA for the petascale Blue Waters system that was expected to go online in the next year. The reason stated was that NCSA found IBM's technology 'was more complex and required significantly increased financial and technical support by IBM beyond its original expectations.' The IT community is now wondering if NCSA will be renting out space in the new data center that is being built to house Blue Waters or if they will go with another vendor." -
World Wide Web Turns 20 Today
girlmad writes "On 6 August 1991, Sir Tim Berners-Lee, then a humble scientist at CERN, made the first page on the World Wide Web publicly available in a move that, unbeknown to him at the time, would change the world more quickly and profoundly than anything before or since." Wired also has a retrospective, noting that "[i]t can be hard now, even for many of us who regularly used the Internet before there was a World Wide Web, to remember that there was a time when the two terms weren’t considered nearly synonymous by the general public." For those who remember, what was your first experience with the Web per se? For me, it was in 1993 or early 1994, with an excited demonstration of Mosaic on Sun workstations in the Geology department at the University of Texas. -
Preserving Virtual Worlds
The Opposable Thumbs blog has an interview with Jerome McDonough of the University of Illinois, who is involved with the Preserving Virtual Worlds project. The goal of the project is to recognize video games as cultural artifacts and to make sure they're accessible by future generations. Here McDonough talks about some of the technical difficulties in doing so: "Take, for example, Star Raiders on the Atari 2600. If you're going to preserve this, you've got a couple of problems. The first is that it is on a cartridge that is designed to work on a particular system that is no longer manufactured. And as long as you've got a hardware dependency there, you're really not going to be able to preserve this material very long. What we have been looking at is how feasible is it for things that fundamentally all have some level of hardware dependency there — even Doom has dependencies on DLLs with an operating system, and on particular chipsets and architectures for playing. How do you take that and turn it into something that isn't as dependent on a particular physical piece of hardware. And to do that, you need information about that platform. You need technical specifications that allow you to basically reproduce a virtualization that may enable you to run the software in its original form in the future. So what we're trying to do is preserve not only the games, but preserve the knowledge that you would need to create a virtualization platform to play the game." -
Strategy Games Improve Cognitive Functions In Older Adults
Researchers at the University of Illinois have completed a study about using video games to stimulate cognitive function in adults over 60 years old. The scientists selected a strategy game — because of its scope and the variety of different tasks involved — and trained a group of subjects on how to play. The gamers then scored better than a control group on a number of cognitive tests. Quoting: "The tests included measures of their ability to switch between tasks, their short-term visual memory, their reasoning skills and their working memory, which is the ability to hold two or more pieces of information in memory and use the information as needed. There were also tests of the subjects' verbal recall, their ability to inhibit certain responses and their ability to identify an object that had been rotated to a greater or lesser degree from its original position. The researchers found that training on the video game did improve the participants' performance on a number of these tests. As a group, the gamers became significantly better — and faster — at switching between tasks compared with the comparison group. Their working memory, as reflected in the tests, also was significantly improved. Their reasoning ability was enhanced. To a lesser extent, their short-term memory of visual cues was better than that of their peers, as was their ability to identify rotated objects." -
Researcher Warns of "Digital Dark Age"
alphadogg writes "A assistant professor from the University of Illinois at Urbana-Champaign is sounding a warning that companies, the government and researchers need to come up with a plan for preserving our increasingly digitized data in light of shifting document management and other software platforms (think WordPerfect and floppy disks). Jerome P. McDonough, who teaches at the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign, says there exists about 369 exabytes worth of data, and that includes some pretty hard to replace stuff, including tax files, email and photos. Open standards could play a key role in any preservation effort, he says. 'If we can't keep today's information alive for future generations, we will lose a lot of our culture,' McDonough said. Even over the course of 10 years, you can have a rapid enough evolution in the ways people store digital information and the programs they use to access it that file formats can fall out of date.'"
