LSUHSC hires surgical robot to remove salivary stone
Louisiana State University's Health Sciences Center has just enlisted the support of a surgical robot "guided by a miniature salivary endoscope" in order to yank a 20mm salivary stone and mend the salivary duct of a 31-year-old patient. A bit gruesome to consider, sure, but it's a whole lot less invasive than removing entire salivary glands as we've had to do in the past. Purportedly, the new procedure saves the salivary gland, cuts down on blood loss, reduces scarring and shortens the accompanying hospital stay. While inside, the robot can also provide high-definition, 3D images, but there doesn't seem to be any public word on when this here doodad will be ready for use outside of a lab. We're guessing it'll get loads of testing done down in Baton Rouge, though -- this Les Miles fellow seems to be giving fans heart attacks, kidney stones and all sorts of other stress-related conditions.
Gurus track inhaled nanoparticles as they experience Mach 5 lung travel
Ever wondered what kind of objects you inhale on a daily basis, leaving your lungs to sort out whatever it is that you snort in? Scientists at the Beth Israel Deaconess Medical Center and the Harvard School of Public Health have, and they're tired of simply imagining. A crew of wizards at the institution have started to test a so-called FLARE system (fluorescence-assisted resection and exploration), which enables them to see and monitor nanoparticles as they enter and travel through the lungs. The goal here is to "determine the characteristics and parameters of inhaled nanoparticles that mediate their uptake into the body -- from the external environment, across the alveolar lung surface and into the lymphatic system and blood stream and eventually to other organs." In short, this here study may offer a better understanding of the health effects surrounding air pollution... or restart the mask-wearing craze that SARS initiated. But probably both.
MIT's laser camera can photograph around corners, render your camouflage useless
You know, we'd love to meet this Ramesh Raskar character. Possibly even shake his hand, or secretly become injected with a pinch of his DNA. You see, he's devoted his life to proving that the impossible is actually possible, first conjuring up a 6D "super-realistic" image system just over two years ago. Now, he's onto bigger and better things... things like cameras that can see around corners. Granted, this concept isn't exactly a new one -- LIDAR-equipped robots have been discovering hidden objects for years, but the mere thought of cramming this technology into a camera has us salivating. Auntie Beeb has a new piece up on the technology, and it actually does an exceptional job of explaining the technobabble. Put simply, the created prototype utilizes an ultra-short, highly intense burst of laser light (a femotosecond laser, if you have to know) to light up a scene; from there, it bends around corners and bounces back, using algorithms to figure out what's inside of the room based on the bounce points. We're guessing it'll still be a few decades before this gets wrapped into a mid-range DSLR, but we're cautiously hoping for a working mockup at CES 2015. Seriously, we just marked it down. Don't disappoint us, guys.
The current state of Mac use in higher education
Apple used to own the Higher Education market throughout the 80s and early 90s. Apple eventually took a back seat to the lower-priced Dell product line, but all of that is changing. According to a Group Logic Inc. survey of IT professionals at 125 North American colleges and universities, use of Macs on campuses has risen and will continue to rise. Between 2009 and 2010, Mac usage increased by 18 percent and is expected to rise by another 20 percent over the next five years. The reason most often given for the recent sharp increase was as a reaction to Microsoft's Vista operating system, which was considered problematic (to use the nicest word I could think of) by students and IT alike. The survey was collected from fairly large institutions, averaging about 16,500 students. On average, 31 percent of students and 24 percent of faculty are currently using Macs on campus. An August report by Student Monitor stated that 27 percent of laptops found on campus were Macs, 24 percent were made by Dell, and 15 percent were Hewlett Packards, easily giving Apple the lion's share of the Higher Education laptop market. The study also found that nearly half of students in the market for a laptop said that they would buy a Mac. Compare that with a survey done in 2005, where only 14 percent of students queried were interested in a Mac laptop, and about half said they were buying a Dell. Windows is still the most prevalent operating system, but the gap is closing. Student Monitor reported that in 2003, over 2500 institutions were using Windows, while only 200 used Macs. By 2008, the gap closed dramatically, with about 2000 institutions using Windows and 1100 using Macs; only a year later, 1700 schools were using Windows compared to 1400 using Macs. What wasn't mentioned in any survey (and seemed a rather obvious thing to leave out): the "halo effect." A major motivating factor in students buying Macs is that so many of them have iPods, iPhones, or iPads and have been impressed by them, making Macs a much easier sell. %Gallery-107378%
Robo-nurse gives gentle bed baths, keeps its laser eye on you (video)
When they're not too busy building creepy little humanoids or lizard-like sand swimmers, researchers at the Georgia Institute of Technology like to concern themselves with helping make healthcare easier. To that end, they've constructed the Cody robot you see above, which has recently been demonstrated successfully wiping away "debris" from a human subject. The goal is simple enough to understand -- aiding the elderly and infirm in keeping up their personal hygiene -- but we'd still struggle to hand over responsibility for granny's care to an autonomous machine equipped with a camera and laser in the place where a head might, or ought to, be. See Cody cleaning up its designer's extremities after the break.
18-screen digital paint wall supports touch, iPad doodling (video)
Look, we all love finger painting. It's an American tradition, after all. But just like nap time, it somehow vanishes into oblivion once adulthood creeps into play. But a sect of kids at the University of Illinois at Chicago aren't about to enter the so-called "real world" without a few more flicks. Researchers at the institution have crafted a digital paint wall out of 18 HD screens. Total resolution? 8160 x 2304 pixels. Better still, the wall is touch-enabled, and if you can't get close enough to doodle, there's an iPad app that lets an extra artist add their touch via WiFi. Currently, it can handle 32 touches at once, and those in charge are hoping to make it play nice with multiple tablets in due time. Hit that play button below for a look at what you're missing, Mr. Grown-Up. [Thanks, Jason]
Dynamic 3D holograms can now refresh every two seconds, save galaxies in their spare time
Perhaps the biggest challenge in making holograms usable on a daily basis -- aside from having to film your subject with a million trillion cameras -- is in getting their refresh rates up to the levels we're used to with "normal" two-dimensional video. We're still a fair way away from those magical 30fps, but the University of Arizona is touting a heretofore unheard of redraw rate of once every two seconds. This is a major advance from their first dynamic holograms demonstrated two years ago, which required minutes to swap over to a new image. The current prototype is built on a 10-inch photorefractive polymer screen, with lasers beaming information onto it, though 17-inch versions are also being tested. Another present limitation is that the hologram displayed can only be of one color, but that is also subject to the continuing labors of the UA researchers, who foresee no major hurdles preventing them from eventually cobbling together full-color, fast-refreshing, and fully realized 3D holograms. Now that'd be 3D television we can all get behind. Or in front of, depending on the viewing angle we want.
UCLA / Caltech researchers help patients move mouse cursors with their brains
It's certainly not a revolutionary new concept -- whiz kids have been tinkering with brain-controlled interfaces for years on end -- but a collaboration between UCLA scientists and colleagues from the California Institute of Technology has taken the idea one leap closer to commercialization. Itzhak Fried, a professor of neurosurgery at UCLA, kept a close watch (via embedded electrodes) on how a dozen humans reacted to certain images, and eventually, Fried and co. were able to show that Earthlings can "regulate the activity of their neurons to intentionally alter the outcome of stimulation." In other words, they were able to move a mouse cursor with just their mind, and brighten a test image with a 70 percent success rate. By honing the process of controlling what actions occur when focused on a given subject (or input peripheral), it opens up the possibility for paralyzed individuals to not only check their email, but also control prosthetic limbs. It's hard to say when this stuff will be put to good use outside of a hospital, but the video after the break definitely makes us long for "sooner" rather than "later."
Shocker! Kids spending too much time in front of TV screens, too little in loving parents' embrace
Not that anyone really needed to have this spelled out, but America's tots are apparently spending too much time in front of the telly tubes. The latest study, conducted by the Seattle Children's Research Institute and the University of Washington, finds that children under the age of five are spending 4.1 hours of each day watching movies or TV, doubling the recommended maximum of two hours a day. Whether you take the slightly arbitrary two-hour RDA to heart or not, it's undeniable that all of us -- not just the young 'uns -- are spending increasingly larger chunks of our time looking at the world through a screen and not through our own retinas. And, if you want an extra topping of alarmist extrapolation, these figures come from a research sample concluded in 2006, today's better-equipped toddlers are very likely to outdo those numbers when mobile devices and the like are factored in. Imagine how bad this would all be if the US didn't have so much quality programming to entertain and educate them with.
NC State gurus find 'Goldilocks' of DNA self-assembly, look to improve drug-delivery vehicles
We're guessing that most Wolfpackers in the greater Raleigh area are in full-on tailgate mode right now, but aside from laying a beating on the Seminoles this evening, NC State faithful are also trumpeting a new DNA discovery that could one day make it easy to get vital drugs to hard-to-reach places within you. Researchers from the university have purportedly discovered the 'Goldilocks' of DNA self-assembly, which holds promise for technologies ranging from drug delivery to molecular sensors. The concept, known as DNA-assisted self-assembly, has been vastly improved by using "computer simulations of DNA strands to identify the optimal length of a DNA strand for self-assembly." You see, perfection occurs when strands aren't long enough to intertwine with each other, yet not short enough to simply fold over on each other. We know, it's a lot to wrap your brain around with half a hot dog shoved in your mouth, but hit the video after the break for a... shall we say, more visual explanation.
Google to beta test 1Gbps fiber internet service at Stanford's Residential Subdivision
Right after having a giant Christmas tree as your mascot comes the next best reason to be a Cardinal: the chance to have 1Gbps internet from Google. If you'll recall, the Big G announced earlier this year that it was planning to rollout a 1Gbps fiber connection to between 50,000 and 500,000 homes in a given community, and while the search is still ongoing for the perfect fit (that's expected to be announced by the year's end), Google's using a sliver of Stanford's campus to trial things before heading public. The university's Residential Subdivision -- a group of approximately 850 faculty- and staff-owned homes on campus -- will be the testing grounds for the aforesaid internet service, and the current plan is to break ground on the initiative in early 2011. El Goog chose Stanford for a couple of reasons: first, it's bright enough to realize how awesome of a PR move this is, and second, this chunk of campus is spitting distance from Mountain View. Third, the Cardinal mascot was down with it -- and seriously, who is Google to question that thing?
iPads join tongue depressors and latex gloves as a hospital fixture
The next time you visit a hospital or medical clinic for a routine check or emergency, don't be surprised if the doctor shows up with an iPad in hand. The Chicago Sun-Times is reporting that in several Windy City hospitals, the iPad is making inroads in a big way. The Loyola University Medical Center has given Apple's tablet to all of its orthopedic residents as a pilot program, while the University of Chicago Medical Center is expanding an existing pilot by providing iPads to all of their internal medicine residents. What are the iPads used for? At the University of Chicago, plastic surgeon Dr. Julie Park shows breast-cancer patients what they may look like after reconstructive surgery. At the Metro South Medical Center, many of the emergency room doctors purchased their own iPads once they found out that they could access the hospital's medical record system from the devices. One Metro South doctor was quoted as saying that the iPads resolved one of the traditional problems with moving from paper to electronic records -- having to go to a desktop computer to order lab tests or update patient notes. Since the iPad is used as a portal device to the record system at Metro South, no patient info is stored on the device. Both the medical record system and iPad are password-protected as well, keeping secure information safe from prying eyes. If you're using an iPad in a hospital or other medical venue, let us know how it's working out by leaving a comment. [via MacDailyNews]
Flexible, implantable LEDs look set to start a new body modification craze
LED lights are cool, you're cool, why not combine the two, right? We doubt that's quite the reasoning that led to this international research project, but it's certainly an appealing way to look at it. Our old buddy John Rogers from the University of Illinois at Urbana-Champaign has headed up a research team with participants from the US, China, Korea, and Singapore, who have together produced and demonstrated a new flexible and implantable LED array. Bettering previous efforts at inserting lights under the human skin, this approach allows for stretching and twisting by as much as 75 percent, while the whole substrate is encased in thin silicon rubber making it waterproof. Basically, it's a green light to subdermal illumination, which could aid such things as monitoring the healing of wounds, activating light-sensitive drug delivery, spectroscopy, and even robotics. By which we're guessing they mean our robot overlords will be able to color-code us more easily. Yeah, that must be it.
Robots learning our pain threshold by punching humans and seeing if they cry
The first rule of robotics is you do not talk about robotics that a robot should not injure a human being or, through inaction, allow a human being to come to harm. But how does a robot know when its acts or omissions are causing nearby fleshies discomfort? The obvious way is to scan for the same signals of distress that we humans do -- facial, physical, and aural -- but another, more fun, way is to just hit people over and over again and ask them how much each blow hurt. That's what professor Borut Povse over in Slovenia is doing, in a research project he describes as "impact emulation," where six test subjects are punched by a robotic arm until they can't take it anymore. It's funny, yes, but it's also novel and a somewhat ingenious way to collect data and produce more intelligent machines. Of course, whether we actually want more intelligent machines is another matter altogether. [Thanks, Anthony]
Elpida and Sharp team up for ReRAM in 2013: 10,000x the speed of current NAND flash chips
Want to know where the next breakthrough in mobile technology will come from? Well, if Elpida and Sharp have their way, the answer will be the usual suspect of Japan, where they're working away on new memory chips said to be capable of four orders of magnitude faster performance than the ordinary NAND flash storage of today. Dubbed ReRAM, or Resistive Random Access Memory, this project targets a 2013 date for commercialization and counts the University of Tokyo and Japan's National Institute of Advanced Industrial Science and Technology among its development team. Details on how such blinding speeds will be reached aren't readily available, but the Nikkei reports power consumption will be down to "virtually zero" when the memory's not in use. So with ReRAM and HP's memristors both set for three years from now, can we schedule NAND's funeral for 2014 or what?
Rat controls vehicle with its brain, Pinky and The Brain apply for 'one last run'
So, let's paint the picture, shall we? There's a rat, a bundle of electrodes, more wiring than an electrician would know what to do with and some sort of wheeled apparatus. In the background stands a team of crazed Japanese scientists, intent on never sleeping again until said rat controls said vehicle entirely with his mind. Nah, it's not a re-run of a WB classic -- it's real life, and it's happening now in a dark, shadowy corner at the University of Tokyo. The RatCar is a newly developed rat-vehicle experiment that researchers hope will open new doors for those with mobility issues; we've seen brain-machine interfaces change the lives of the disabled before, but giving them the ability to control their wheelchair with their mind (for instance) would be taking things to an entirely new level. As of now, the team still has to figure out how to accurately determine how much movement is coming from the rat's feet and how much is coming from its mind, but there's no question that the research shows promise -- just don't let the humanoids learn of our findings, okay folks?
NC State patents multifunctional smart sensors, looks to 'revolutionize energy and communications infrastructure'
Bold words coming from a program that choked in epic fashion this past Saturday in front of 58,000+, don't you think? Thankfully for those who are actually involved in the global energy and communications infrastructure (not to mention depressed alumni), NC State's athletics department is far removed from its research labs, and the university's latest development was born and bred in the latter. A team of researchers have managed to patent a new technology that is expected to enable the development of "high-power, high-voltage and high-current devices that are critical for the development of energy distribution devices, such as smart grid technology and high-frequency military communications." The secret? Integrating gallium nitride (GaN) sensors and devices directly into silicon-based computer chips, a feat that hasn't been accomplished by any team prior. According to Dr. Jay Narayan, this newfangled integration has "enabled the creation of multifunctional smart sensors, high-electron mobility transistors, high-power devices, and high-voltage switches for smart grids," and it also makes a broader range of radio frequencies available -- something that'll obviously be beneficial in the advancement of communications. Best of all, a US-based corporation is already in the process of licensing the technology, so it's likely that we'll see this in use in the not-too-distant future. An ACC championship, however, remains far more elusive.
Neurosurgeons use MRI-guided lasers to 'cook' brain tumors
In the seemingly perpetual battle to rid this planet of cancer, a team of neurosurgeons from Washington University are using a new MRI-guided high-intensity laser probe to "cook" brain tumors that would otherwise be completely inoperable. According to Dr. Eric C. Leuthardt, this procedure "offers hope to certain patients who had few or no options before," with the laser baking the cancer cells deep within the brain while leaving the good tissue around it unmarred. The best part, however, is that this is already moving beyond the laboratory, with a pair of doctors at Barnes-Jewish Hospital using it successfully on a patient last month. Regrettably, just three hospitals at the moment are equipped with the Monteris AutoLITT device, but if we know anything about anything related to lasers, it'll be everywhere in no time flat.
What would happen if you put your hand in the Large Hadron Collider? Er, well, um... (video)
Scientists, they've made our lives infinitely easier, healthier, and longer, but sometimes even their giant intellects can be stumped. Here we have a perfect example of such a scenario, where the seemingly innocuous question of what might happen if one were to dip a hand inside the Large Hadron Collider has generated a wide range of hypotheses, none of which sound particularly assured of being correct. The trouble is that, aside from the known unknowns -- such as whether the accelerated protons would crash and explode upon contact with your hand or just pass through -- there are surely unknown unknowns that will likely become apparent only once you try to do the act itself. So, any volunteers?
UTexas researchers develop organic battery, aim for week-long use in smartphones
Christopher Bielawski, a brilliant mind working at the University of Texas at Austin, had this to say about his newest discovery: "I would love it if my iPhone was thinner and lighter, and the battery lasted a month or even a week instead of a day; with an organic battery, it may be possible." Anyone that has ever owned an iPhone (or a smartphone or any sort, really) can grok just how bold those words are, but according to Mr. Bielawski, "we're now starting to get a handle on the fundamental chemistry needed to make this dream a commercial reality." At the center of this potential revolution is a newfangled organic battery recently detailed in the journal Science, but just as important is the artificial photosynthesis that the research also touches on. Bielawski and colleague Jonathan Sessler have seemingly figured out how to create an electron transfer process that can proceed in the opposite direction, with this forward and backward switching of electron flow opening up new avenues for the historically stagnant battery innovation market. Granted, these guys have yet to demonstrate that the process can occur in a condensed phase, so actual commercialization is probably a century millennium or two out, but hey -- at least our list of "awesome thing that'll probably never happen" has grown by one.
