    We'll admit, we too noticed the stark irony in Sony -- the firm at least somewhat responsible for recalling millions of potentially harmful batteries -- releasing a gizmo to benefit the medical field, but regardless, we can't deny the impressiveness of the PDW-70MD XDCAM HD recorder. While we caught wind of this thing awhile back, it's now getting official with a full list of specs and a hefty pricetag to boot. Taking high definition recording to a field that can genuinely benefit from more detailed captures, the device can "record and store up to two hours of MPEG2 video on a 23GB PFD-23 XDCAM disc" (wasn't this another failed attempt by Sony's proprietary format department?), which is sealed to help prevent scratches and "preserve data with minimal degradation for more than 50 years." Doctors can store HD video of medical procedures in crisp 1,440 x 1,080 resolution, view colored thumbnails of the footage on the 3.5-inch LCD monitor, and control the action with the bevy of front-mounted controls. Of course, the two biggest factors that prove the PDW-70MD is tailored for medical use is the inability to use a recordable format that the general public can acquire (and afford), and moreover, the $14,995 pricetag that only cash-generating hospitals are likely to glance over.[Via MedGadget]

    It's a miracle that Lance Cpl. John McClellan survived a bullet to the head while stationed in Haditha, Iraq -- the sniper's bullet missed his carotid artery by less than a millimeter -- but his recovery afterwards is perhaps equally miraculous. The injury -- one of three he has received on duty -- left McClellan without the use of his left hand and leg. His rehab facility gave him a rubber stress ball to exercise his hand, but John had a better idea: videogames. Specifically, McClellan picked up an Xbox 360. His favorite "exercise" is currently Gears of War, which he plays for four hours a day -- and this is after coming home from four hours at his local rehabilitation facility. Initially, Gears was "too fast," but his game is improving as his left hand's dexterity improves. Nice work, John! Keep it up. Maybe he'll move on to Geometry Wars next ....[Via Joystiq]

    The Johns Hopkins University must employ some seriously bright folks, as researchers at the school are unveiling yet another marvel to benefit mankind, and this time their creation is headed for the nooks and crannies within your body that surgeons have difficulty reaching unassisted. Sure, the diminutive locales within your guts have been explored by robotic creatures before, but these "snake-like robots" could enable surgeons, operating in the narrow throat region in particular, to make "incisions and tie sutures with greater dexterity and precision." The invention consists of two thin rods tipped with "tentaclelike tools" capable of moving with six degrees of freedom; during surgery, the doctor would utilize a 3D visualization system to watch, control, and dictate the robotic tubes. Moreover, the snakes are crafted from nonferrous metals so it can be used around magnetic imaging equipment, and considering its ability to "make up 100 adjustments per second," nimbleness is in its nature. But if you're not exactly fond of such slithering creatures, you've still got time to escape, as researchers estimate that there's still about "five more years" of lab testing before we see Snakes on a Hospital Bed.[Via Physorg]

  • Epilepsy and games: A closer look

    Anyone who plays video games has probably come across the scary-sounding warnings about epileptic seizures that affect "a very small portion of the population." But it's still a bit shocking to stumble across a headline that urges reader to "Beware! Video game turn kids epileptic."The sensationalistic headline in the Hindustan Times is a bit misleading -- as the Epilepsy Therapy Development Project (ETDP) explains, "playing video games can, in rare cases, trigger seizures, but there is no scientific evidence that video games can cause epilepsy." Still, the article points out how otherwise normal children who have not yet been diagnosed with epilepsy can have scary, violent, seemingly unexplained fits when exposed to certain games.Research shows that while 1 in 200 people have some form of epilepsy, only about 1 in 4,000 have the photosensitive type that can be triggered by video games. That might not sound like much, but multiplied over tens of millions of video game players it adds up to thousands of people who are potentially susceptible.ETDP has some suggestions for preventing the risk of seizure, including playing in a well lit room and playing for shorter periods of time. NIH suggests that TVs running at 100 Hertz won't induce seizures, and that some children simply outgrow the problem as they get older. In short, while video game-induced epilepsy is something to keep an eye out for, it's not something to be overly panicked about.

    While we actually gave away a shaver not too far back to help the, um, hygienically challenged out there, leave it to Brando to deliver the first shaver geeks will actually use. Joining the gazillion other oddities that sufficiently eliminate the "lonely USB port" syndrome, this bathroom necessity features a floating double-head system, "ultra thin outer foil," low power consumption, snazzy blue LEDs, a revolving USB plug, and an on / off switch. Completely rechargeable via your trusty USB port, this gives a new meaning to "portable shaving system," and gives you one more reason to just spend the night in your office versus fighting that awful rush hour traffic. So if you're looking to drop a not-so-subtle hint to that beastly friend of yours, you can wrap this sucka up for just $22.

    There's not much like getting off the couch and moving around a bit (well, not always), and a Swedish dissertation has uncovered an intelligent wheelchair that sports remote-controlled or autonomous operation. Sven Rönnbäck of Luleå University of Technology in Sweden has developed the Mobile Internet Connected Assistant (MICA), which offers up a presumably comfortable looking set of wheels to those who lack the ability to move on their own. Similar to the technology found in the Good Bytes Cafe, this wheelchair utilizes the built-in "distance-metering sensor to discover the surfaces that are available," and the technology can also be used to "ensure that the wheelchair is being used in a safe manner." The target market is "severely handicapped individuals who would otherwise find it difficult to steer a wheelchair," as these folks could take full advantage of the head-controlled interface in order to instruct the machine where to go next. Best of all, the device can learn and store maps of one's home, giving blind and visually impaired individuals the chance to cart around their crib without worrying over foreign objects foiling their plans. While we haven't heard of any VCs grabbing hold of this marvel just yet, we're sure that opportunity isn't too far away, and we're all about finding new ways to blaze a path.

    In an attempt to bring the computing universe we privileged folk know and love so well to those with limited mobility, Goodwill Industries has opened a free internet café in San Antonio, Texas where wheelchairs are more than welcome. The firm, most commonly associated with its numerous thrift stores and handicapped job placement services, hopes that the normal looking café will take off and encourage disabled / elderly individuals to come and learn about computing skills that can assist them in their daily lives and with locating a job. Good Bytes Cafe, as it's so aptly-named, features the same standard layout of any coffee house, but features a bevy of highly sophisticated PCs for users with limited reach and movement capabilities. Thanks to a $125,000 grant from the local AT&T branch, users have access to software that "magnifies and reads aloud to help those who are visually impaired," joystick mice that are easier to control, an optical-based mouse that controls the cursor with your eyes, and even a minuscule face-mounted controller that directs the cursor by simply moving one's head or nose. Folks attending the grand opening were more than pleased, and one deaf individual went so far as to deem the hangout "absolutely awesome." Rebecca Helterbrand, marketing vice president for Goodwill Industries of San Antonio, is proud of the opening, but hopes that they'll be far "from the last."

  • Cellphones finally cleared of cancer charges

    We've seen so many chapters of the "dangerous / not dangerous" chronicles with regard to cellphone radiation that we've lost count, but thanks to a Danish study recently carried out on 420,000 avid mobile users, we can finally put those worries to rest (we hope). While it's no secret that mobile phone antennas emit "electromagnetic fields that can penetrate the human brain," we've been yearning for a study such as this to quiet the tin-foil advocates (and ensure our own safety). Researchers from the Danish Institute of Cancer Epidemiology in Copenhagen looked at data on people who had been using mobile phones "from as far back as 1982" in order to draw their conclusions, and after all was said and done, they found "no evidence to suggest users had a higher risk of tumors in the brain, eye, or salivary gland, or developing leukemia." Thankfully, a similar study published earlier this year by the Institute of Cancer Research also concluded that mobile phone use "was not associated with a greater risk of brain cancer." So, there you have it folks, you can safely yap away without fear of mutating into some form of diseased being -- until the next study "proves" otherwise, of course.[Thanks, Billfred]

    While we've seen a few snazzy band-aids in our day, not to mention talking first aid kits, a nanofiber bandage that can heal typical skin wounds faster is about to go mainstream. University of Akron professors Daniel Smith and Darrell Reneker are growing ever closer to bringing their invention to life, as a trial just wrapped up in Columbia that they hope will "win them FDA approval for clinical trials in the United States." The duo used electricity to spin ultrafine polymer fibers while infusing them with chemicals that open a wound to oxygen; then, the treated fibers "reduce inflammation, kill bacteria and repair slow-healing wounds faster than conventional methods," according to Smith. Moreover, the creators have already found a Minnesota-based firm willing to mass produce the nanobandages should they receive the green light, but the professors are hoping to build the new manufacturing plant in Ohio if at all possible, and have products on retail shelves "by 2008" at the latest. Given the presumed popularity of the quick-healing bandages, the team is continuing to work on other "nanofiber products" in their spare time, hoping that the mending aid is just the beginning of a long line of sweet nano-based products to come.[Via MedGadget]

  • ATRS to make entering / exiting vehicles easier for handicapped individuals

    While there's certainly smart enough wheelchairs to get you around town without mauling a lamppost or taking out a crowd of bystanders, a Pennsylvania-based team has developed a system to get wheelchair-bound individuals in and out of their cars a lot easier. Engineers at Lehigh and Carnegie Mellon have partnered with robotic startup Freedom Sciences LLC and Freedom Lift Corporation to unveil the Automatic Transport and Retrieval System, which will supposedly "enable wheelchair users to drive while sitting in standard automobile seats that meet federal safety regulations." Currently, motorists are forced to use cumbersome, bolt-in attachments that typically require heavy modifications to the car in order to operate; the ATRS system, however, uses remote controls, wireless technologies, and "lasers" to assist drivers into a standard seat, roll their wheelchair "autonomously" to the loading dock, and close up the rear door, all while parked in the driver's seat. Sensational as it may sound, the system doesn't come cheap (nor with a wheelchair), and will cost handicapped individuals (or insurance companies) between "$15,000 and $20,000" when it goes on sale next spring.

  • UK doctor puts the smackdown on WiFi fearmongers

    Ok, folks, listen up: this whole WiFi health thing is starting to get a little out of hand. In response to an issue that The Times reported on late last month, where some UK schools were pulling the plug on their local wireless networks due to health concerns, the newspaper has now done a bit more investigating into its health effects, perceived or otherwise. It interviewed various pundits on both sides, but one of the most powerful arguments was made by Dr. Michael Clark, of the UK's Health Protection Agency, who said: "As a comparison, a child on a mobile phone receives up to 50 per cent of guideline levels. So a year sitting in a classroom near a wireless network is roughly equivalent to 20 minutes on a mobile. If WiFi should be taken out of schools, then the mobile phone network should be shut down, too - and FM radio and TV, as the strength of their signals is similar to that from WiFi in classrooms." Further, there are also concerns about electrosensitivity -- people who claim to be physically injured due to electromagnetic waves that propagate from WiFi equipment. As both The Times article, and WiFi expert Glenn Fleishman suggest, one simple way to determine whether or not this is actually true would be to conduct a double-blind test. Honestly, you government experts and anti-WiFi folks, would that be so hard?Read - The TimesRead - Wi-Fi Net News[Via Techdirt]

  • Philips patents razor light technology to zap hair growth

    While most folks aren't exactly fond of going bald on their noggin, eliminating the pesky hair on faces and legs doesn't sound half bad. Aside from the gazillion topical treatments scams available at your local Wally World, there's always the uber-expensive "laser hair removal" option, but Philips seems to think it has a less costly, less intrusive solution. The firm has recently patented razor light technology, which utilizes "low doses of electromagnetic radiation" to kick active follicles into the dormant catagen phase. By sending pulses "between 1 and 100 milliseconds" apart just above the skin, it offers up a relatively safe, easy, and (hopefully) pain free experience to putting a halt to shaving every other day (or more). Obviously, the method isn't aimed at immediate hair removal, as plans are to implement numerous treatments over "two week intervals," but it could slowly eliminate the regrowth of hair once treated. So while we're not exactly sure when you'll be replacing that bag of disposables with a newfangled light gun, a little help in the hygiene department is never a bad thing.[Via NewScientistTech]

  • Medical students treat dummies that bleed, speak, and die

    While there's always the off chance that your next surgery will be completed by a robotic doctor, we'd wager that most of us would opt for a well-trained, well-rested, and naturally conceived expert to handle the tools. The University of Portsmouth is upping the ante on its training facilities for those making the rounds in med school, and doctors-to-be now have access to £135,000 ($266,706) dummies that "bleed, speak, and potentially die" depending on the level of care received. Providing a more realistic practice environment, these lifelike mannequins can also "breathe oxygen, drool, secrete fluids, blink, and even react to drugs injected into their bodies." Aside from being used by students of medicine, social work, and dentistry, police and firefighters will also be able to get their hands dirty, but they'll be forced to treat the creature as a real human, taking notice of their names, biographies, and medical history before picking up that needle. Additionally, users will be able to access the built-in cameras and microphones to "critically appraise performances in real time." So if you're looking for a second opinion, tracking down a recent Portsmouth graduate that trained on these blokes might not be such a bad idea.[Via Smart Mobs]

  • Haptic systems to bring feeling back to robotic instruments

    We've heard some very intelligent humans suggest that computerized beings just might be a bit more adept at handling complicated tasks, but some things just require a little TLC from the human hand. While even the operating room wasn't safe from robotic takeover, researchers at The Johns Hopkins University are testing new ways to bring real feelings back to human doctors using robotic helpers in order to operate. Straight from a chapter in Trauma Center, the team is developing haptic technologies to provide close-to-real feedback to surgeons while handling robotic tools. One option undergoing testing is the attachment of "force sensors" to instruments, which are capable of conveying details about force, direction, and depth that are critical when performing incisions and other precise tasks. The alternative is to "create mathematical computer models" that represent tool movements, and consequently relay the haptic data back to the person in charge. While kinks continue to be worked out in the primary methods, researchers have developed an "interim" system that uses color-based sensors to inform doctors how much pressure is being applied (i.e. red for intense pressure, green for light), and the team plans on "refining the systems" to produce a more usable result in the near future.[Via MedGadget]

  • More "proof" that violent video games breed rage

    While we've already learned that television shows pull double duty as entertainment and a sedative, and that launching a console with a widely understood shortage hitting stores can cause all sorts of madness and criminal activity to break loose, the last thing we needed was one more "study" claiming that video games breed rage. But nevertheless, researchers at the Indiana University School of Medicine have discovered that "teenagers' brains become fired up" (read: angered) after playing violent video games. A survey using 44 same-sexed humans with "similar IQs and age" showed that a half hour of violent gaming "increased activity within the amygdala (involved in emotional arousal)" while simultaneously decreasing activity in "parts of the brain involved in self-control" -- unsurprisingly, the opposite effects were seen when gamers were forced to play non-violent titles. However, when all the fMRIs were completed and reports were being compiled, the doctors still noted that "further studies were needed to determine whether these physiological changes actually make individuals behave more violently," so until that's proven absolutely, we're sticking to our (pixelated) guns.[Thanks, Nate W.]

    Alright Europe, things were dubious enough when you erased children's rights to wireless access after believing that the radiation a good chunk of internet users have been subjecting themselves to for years is suddenly cause for concern, but this is a bit much. Undoubtedly crossing the line between caution and hypochondria, a British author now claims that "electromagnetic waves" emitted by the WiFi setup in her crib "left her feeling exhausted, nauseous and sleepless." Moreover, she even states that she is so sensitive to 802.11 radiation that "she can instantly tell whether it is installed in a particular room." Aside from the above symptoms, Kate Figes (pictured) described a feeling of being "prodded by 1,000 fingers" when entering a room laced in WiFi, which presumably garnered all sorts of (understandable) skepticism. Sure, we could understand the backlash associated with cellphone signals causing all sorts of turmoil in your noggin, but if WiFi is the true brain cell killer, we're all pretty much on death row.[Via TechDirt]

  • UK schools pull the plug on WiFi for alleged health reasons

    Back in February, we told you about how Lakehead University in Canada was restricting WiFi usage for health concerns. Well, not to be outdone by a former colony, similar issues have cropped up in the UK at a handful of schools in Chichester, Carmarthenshire, and Buckinghamshire, which have turned off their WiFi citing parental lobbying. One parent, Judith Davies, whose daughter attends a school in Carmarthenshire, told The Times: "Many people campaign against mobile phone masts near schools, but there is a great deal of ignorance about wireless computer networks. Yet they are like having a phone mast in the classroom and the transmitters are placed very close to the children." Ms. Davies, we don't mean to be rude, but have you ever seen a WiFi router? They're really small, use much less power, have a much shorter range, and give off way less radio frequency radiation than your average cell phone tower. Put into technical terms, most WiFi routers have a peak power output of 100 mW (compared to most cellphones, which output at around 2 W). So, assuming that your child isn't sitting right on top of said router, she'll most likely be perfectly fine. And even if she is sitting on top of a router, aside from being somewhat uncomfortable she'll still probably be perfectly fine.[Via TechDirt]Read - The Times

    While having your entire catalog of medical issues on your person at all times would sure come in handy if your GPS leads you into a body of water or you get mangled by a Japanese Land Walker, implanting an RFID data chip underneath your skin could (understandably) sound a bit extreme. While digital medical records and emergency panic buttons are certainly swell, EMI's 911 rCard places every quirk and prior health issue you've ever had onto a single wallet-sized card, which can be viewed immediately by any medical personnel that would need pertinent information statinum. The "vivid, full color LCD" can display everything from medical charts to photos / text describing the patient's history, and sports a built-in battery that can handle "about two hours" of constant viewing before it needs recharging. Boasting USB connectivity, users can continually update and upload new information from their EMI web portal onto the rCard, including any mild injuries sustained during last week's campouts. The 911 rCard is available now for $79.95, which includes a USB cable / charger and the first year of website access, while additional years of data storage and interfacing will run you $20.[Via EverythingUSB]

    If you think playing tennis (or pwning your television) with a Wiimote is revolutionary, how'd you feel about wheeling through downtown sidewalks without ever moving your fingers, hands, or arms? Doctors and researchers from Northwestern University and the University of Pisa have crafted a sensor-laden shirt "that could help seriously paralyzed individuals steer their wheelchairs." The garment is printed with "52 flexible, piezoresistive sensors made of electroactive polymers that change voltage depending on the angle at which they are stretched." By dynamically sensing the direction and intentions of the user, it can channel the signals to motorized chairs in order to perspicaciously propel severely handicapped individuals who have lost the use of their arms. The team has tested the unit on a paralyzed individual (pictured) in a virtual training maze, where the shirt "learned and adapted" to his specific notions to guide him successfully through the course. While the team envisions the shirt becoming even more useful by possibly adding shoulder sensors for other types of disabilities, they haven't ruled out its use in "other applications" -- and hey, we've got no digs with adding even more motion-sensing goodness to our games.[Via MedGadget]

    While ridiculously small robots crawling around in our bodies seems quite painful (and in some cases, it is), a team headed by Moshe Shoham of Haifa's Technion is developing a smoother riding robot to cruise the friendly passageways of the spinal canal. Dubbed the SpineAssist, this low-powered microbot is being crafted to "aid surgeons in performing delicate spinal procedures" by propelling itself through the water-like cerebral spinal fluid and channeling live video / snapshots back to the doctors in charge. Researchers have already engineered the propulsion system, and describe the device as a "free-swimming endoscope" with two actuators and swimming tails that will lug a camera into the fragile depths. Shoham estimates that a few more years of work will be needed to up its payload capacity and shrink it to an appropriate size, but at least someone's working on taking the back aches out of surgery, eh?[Thanks, William]
