    The Conus regius' venom is bad news for its prey, and it's been proven harmful to humans as well. For instance, a 2009 clinical case describes a diver who had trouble moving his arm for 12 hours after an attack. However, scientists from the University of Utah see hope in the ocean dweller's powerful venom. In fact, research suggests it could be used to develop a new treatment for chronic pain.

    For the past century or so, we've been making ammonia the same way that Nobel-prize winning chemist Fritz Haber did: by smashing hydrogen and nitrogen gas together at 250 atmospheres and heating them to nearly 1000 degrees F. But a new method developed at the University of Utah turns that process on its head.

    They're not very pretty, but prototype eyeglasses from University of Utah scientists could make progressive lenses obsolete for older people. Using electronically activated lenses and infrared distance meters, they can focus automatically on whatever you're looking at, whether it's far or close up. Once perfected, the device could eliminate the need for multiple pairs of reading or driving glasses for folks with presbyopia or farsightedness.

The results are pretty terrible: Apparently it takes a full 27 seconds for a driver to fully concentrate after attempting to call someone while behind the wheel. Meanwhile Florida may be good for something beyond just the best Twitter account this side of the Atlantic. Researchers there found a strain of deep-sea bacteria that might be able to help fight global warming by attacking greenhouse gases. And a Spaniard got the first implanted 3D printed ribs in the world after a cancer fight. Good on him!

    We all know that taking your eyes off the road is a bad idea, but now researchers have added another paper to confirm that using voice commands is just as unwise. A team from the University of Utah, in partnership with the American Automobile Association, believes that the mental effort of driving and talking on your phone is still dangerous. According to the research, it takes a full 27 seconds after completing a distracting task — queuing up a song even with your voice alone — before your brain is fully able to concentrate on the art of driving.

    Fuel cells may be a practical reality, but there aren't many choices for the fuel itself -- you usually have to rely on hydrogen, which dictates where and how those cells work. The University of Utah may have a clever alternative in store, however. Its researchers have developed a cell that runs on JP-8, a jet fuel used by American warplanes in harsh climates. The cell uses enzymes to turn propellant into electricity without requiring lots of heat or a perfectly clean mixture; it works at room temperatures even when there's sulfur in the mix, making it far more useful than previous attempts at JP-8 cells.

    Spintronics? Not exactly a new term 'round these parts, but University of Utah physicists are applying it in a unique way that may eventually make TVs look even sharper than they do today. The entity is trumpeting a new "spintronic" organic light-emitting diode (that's OLED, for short) that's said to be "cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices." Z. Valy Vardeny is even going so far as to call it a "completely different technology," and better still, a prototype has already been made. The professor expects that the newfangled tech -- which produces an orange glow today -- will be able to product red, blue and white spin OLEDs within a few years. It's a lot to wade through, but here's our question: will these things make the Galaxy S XI impeccably visible in outdoor sunlight? (Please say "yes.")

  • Accelerometer mic could change the way we look at cochlear implants

    Hearing aids aren't the most discreet cybernetic creations, because the need for a clog-free microphone means that they generally need an external component. Engineers at the University of Utah and Case Western Reserve University in Cleveland aim to change everything with a much smaller mic that uses an accelerometer to detect sound vibrations -- so it requires no opening and can be inserted right into the ear. The only exterior hardware is the charger -- worn exclusively at night. Clinical trials in living humans begin approximately three years from now, and if you're looking forward to using this new device, removal of the incus (or anvil bone) in the middle-ear must first take place to optimize effectiveness of the new implant. We never said it'd be pretty.

    Just when you thought slingshots were the future, here comes a whole new way to enjoy baddie deletion in Uncharted 7. Each thumbstick on the prototype controller above has a secondary force feedback-enabled nub at its center, which moves independently and creates different sensations by stretching the skin on the pad of your opposable digit. In the video after the break, the designers at the University of Utah show how they've created effects for crawling, collisions, explosions and even fishing. They're apparently hoping to push their technology into next-gen games consoles, but they'll have to join the queue.

  • Researchers use wireless network to monitor breathing, could save lives

    When Neal Patwari and his team of researchers developed a wireless network capable of seeing through walls, we assumed they were simply looking to cultivate their Alastor Moody-like superpowers. Turns out, they had far more important things on their minds. Patwari and his colleagues at the University of Utah have now penned a new study in which they demonstrate how their motion detecting technology could be used to monitor breathing patterns, as well, potentially enabling doctors to keep closer track of patients with sleep apnea or babies susceptible to sudden infant death syndrome (SIDS). To do this, Patwari reclined on a hospital bed and surrounded himself with 20 wireless transceivers operating at a frequency of 2.4GHz, as pictured above. He then timed his breathing at about 15 breaths per minute (the average rate for a resting adult), which he measured with his array of nodes and a carbon dioxide monitor. The engineer ultimately found that his system's algorithm could accurately measure respiration within 0.4 to 0.2 breaths per minute -- a relatively low error rate, since most monitors round off to the nearest full breath. Patwari says this development could offer a non-invasive and low-cost alternative to the devices used in most hospitals, and hopes to implement his technology into at-home baby monitors, as well. He acknowledges, however, that it will likely take at least five years before any of that happens -- so don't hold your breath. Full PR after the break.

  • Lasers let deaf ears pick up what the sonic world is putting down

    Not going to front: we've a soft spot in our heart for focused beams of light. We've seen 'em rid the world of its space junk and set the pace of human hearts, and now, they're taking a leading role in aural advancement. As improbable as it sounds, a research team from the University of Utah led by Richard Rabbitt has found that lasers may be able to give deaf people the ability to hear. Using a low-power infrared diode -- similar to those in laser-pointers tormenting cats the world over -- Professor Rabbitt found that exposing oyster toadfish hair cells (analogous to the cells found in humans' inner ears) to infrared light caused them to release neurotransmitters and activate adjacent neurons. This could lead to laser-based ear implants able to stimulate focused areas of cells with thousands of sound wavelengths, as opposed to today's electrode implants whose electrical current spreads through human tissue and limits the deliverable sonic range. Smaller, more efficient power supplies and light sources are needed before optical hearing aids become a reality, but if these newfangled lasers ever get their act together, we should be able to hear version two (and three) coming down the pike.

  • This is your brain. This is your brain on video games

    Sure, you've probably seen countless scientific studies involving video games -- but have you have you ever wondered what your brain actually looked like while your playing video games? Well, feast your eyes on the image above. That's an MRI scan of New York Times writer Matt Richtel's brain that was captured while he played a simple driving game -- all in the name of science (and journalism), of course. As Richtel notes, however, that's just one example of the ways researchers are using such technology to "map the ethereal concept of attention," and scientists have turned up some other interesting findings as of late. Researchers at the University of Utah, for instance, have found that people's ability to juggle two tasks begins to drop off in their 30s and then sharply drops in their 40s, which contradicts earlier suspicions that people's ability to multitask only began to degrade when they're much older. Some other researchers are still suspicious of those findings, however, and Dr. Gazzaley of the University of California at San Diego is quick to point out that all of this research is still in the earliest stages -- he's expecting some more detailed findings next year when his team expands their tests and begin to incorporate EEG monitoring as well.

    Research at the University of Utah could lead to burn treatment on the go that makes use of your body's own cells. Surgeons Amit Patel and Amalia Cochran are researching the use of stem cells in conjunction with several chemicals as a spray-on jelly which has, in early testing, shown to accelerate the healing process of burns. While the team is starting with small burns, its goal is to be able to provide fast and effective, actual regeneration of a patient's own cells to be grafted onto large area burns. Video of the project is after the break.

    Keeping your eyes on the road gets ever more difficult with ever-bigger, ever-brighter GPS navigation units hitting retail. This product of University of Utah research could obsolete them entirely by tickling your fingers. It's called "shear feedback," effectively stretching the skin on your fingertip to tell you which way to go, achieved via a pair of old Thinkpad trackpoints, which were always too coarse a grit for our delicate tastes. The nub moves left or right to tell you where to go, and in a test distracted drivers were 24 percent more likely to follow directions through their digits than when told by cold, uncaring GPS lady. It's demonstrated after the break and looks like it would be perfect if we always drove at ten and two -- and wanted to get our fingerprints sandpapered off on every trip to the mall.

    ROCR -- the Oscillating Climbing Robot -- was developed at the University of Utah by William Provancher. Its main talent is the ability to climb carpeted walls by using its hook-like claws and is powered by a motor and a pendulum tail that wings like a grandfather clock. Designed to move efficiently and in the vein of a human rock climber, ROCR is able to climb an 8-foot carpeted wall in just about 15 seconds. The team's findings will be published in Transactions on Mechatronics this month, and while future applications include possible uses as an inspection or maintenance tool, Provancher says that in the short term, ROCR will likely be used for education or as a "really cool toy." Video is below.

  • Eye-tracking lie detectors inch a little closer to reality

    If lie detection is your thing, choices aren't exactly scarce: you can go with Lego for the kids, Skype-centric for remote fibber identification, or even use a headband if you can corral your suspect long enough. Hoping to add to that list is the University of Utah, whose eye-tracking lie detector has been licensed to a local company in order to explore its viability as a commercial product. As with Blade Runnner's Voight-Kampff empathy test, Utah's methodology revolves around monitoring things like eye movement, pupil dilation and response time -- with the major difference being that you're trying to identify truth evaders rather than skinjobs. John Kircher, one of the lead researchers, claims results so far have been as good as or better than those obtained with polygraph testing, though he admits the project is still in its early stages. No worries, though, we're sure they'll perfect the technique in time for our post-apocalyptic, Vangelis-scored future.

  • Researchers create Amazing X-Ray Wireless Network!

    Don't freak out or anything, but those wireless signals you bask in everyday could be watching you. Or at least they might, someday, if the work from a group of researchers at the University of Utah makes it beyond the lab. As Technology Review's Physics arXiv blog reports, they've devised a means to modify a standard 802.15.4 wireless network (commonly used by home automation services like ZigBee) to actually "see" movement through walls, and with some degree of accuracy, no less. As you might expect, however, that's not quite as simple as a firmware upgrade, and currently requires a 34-node network to keep watch on a standard living room, which is apparently enough to pin down moving objects within a meter or so. To do that, the system essentially bombards the space with an array of wireless signals and keeps watch on any changes in signal strength, building up a "picture" of the room in the process. No promises on a commercial version just yet, but the researchers see plenty of potential for it, and are even talking about a portable, GPS-equipped version that police or emergency responders could use before entering a dangerous area.

  • Video: simulated 'quiet zone' cloaking hides an object in 2-D

    You don't have to be able to pick a Romulan out of a crowd of Vulcans to be intrigued by the idea of cloaking, and indeed many non-trekkers have tried to hide things in plain sight using electromagnetism, acoustic superlenses, or light-bending materials. The latest attempt relies on devices that emit cancelling waves of the sort anyone who's ever seen a Bose commercial should quite familiar with, combining to negate any external, incoming waves. What's different here is that they also recombine on the other side of the object being cloaked, as shown in the video below, meaning that incoming surge is then re-generated and continues on undisturbed -- potentially even reflecting back through the object again should it hit something on the far side. It's part of research at the University of Utah and, for now, only works in a theoretical two-dimensional world where triangles and squares are ruled by pentagons, hexagons, and priestly polygons. Optical camouflage is sadly not believed to be possible using this technique, but sonar and radar are likely implementations, as well as mechanisms to subvert earthquakes, tsunamis, and maybe even neighboring speed metal fans.

  • Brain Carpet microelectrodes could help translate thoughts into actions more effectively

    Researchers at the University of Utah have developed a new, more precise way of placing microelectrodes on the surface of the brain to enable patients to turn thoughts into action. Led by Bradley Greger, a professor of bioengineering, the "Brain Carpet" as it's called, represents a "modest advance" in techniques already in use. The Brain Carpet makes use of smaller microelectrodes, and also employs many more than are usually used. The method involves sawing off the skull of the patient, then placing 32 electrodes about 2mm apart on the surface of the brain. Though they've conducted tests on just a handful of patients -- all epileptics -- the technique, they believe could also be used to help people control their prosthetic limbs much more effectively. The electrodes allow detection of the electric signals in the brain which control arm and hand movements. In the tests, patients have successfully controlled a cursor on a computer screen following the operation, and they see applications for brain-machine interface devices in the future. There's no word on when the Brain Carpet will move from the research to reality phase, but the group's findings have just recently appeared in the journal Neurosurgical Focus.

  • Researchers take aim at terahertz computing

    It's not everyday that researchers make some progress towards terahertz computing, but a team from the University of Utah led by Ajay Nahata appear to have done just that, with them announcing that they've "taken a first step to making circuits that can harness or guide terahertz radiation." That, they say, could allow for the development of "superfast circuits, computers and communications," and "in a minimum of 10 years," no less. The key to this latest development, it seems, is the use of some sheets of stainless steel foil perforated with tiny holes, which can be arranged in different patterns to effectively form "wires" to carry the terahertz radiation. In their tests, the researchers were able to do so at a level of 300Ghz (or 0.3 terahertz), although they admit that they still have a long way to go, saying that "all we've done is made the wires" for terahertz circuits, and adding that there still needs to be devices like switches, transistors and modulators developed at terahertz frequencies in order for anything practical to become possible.[Via TG Daily]
