Good Bytes Cafe gives internet, computer access to the disabled
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]
Nanofiber bandages slated to heal en masse next year
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.
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.]
EMI puts your medical history on a digital business card
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]
Sensor-clad shirt directs wheelchair sans use of arms, hands
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]
SpineAssist robot tours spinal canal with camera in tow
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]
Researchers developing danger-sensing BioPen
Scientists at Ben Gurion University in Israel are out to make detecting dangerous biological agents as simple as a pregnancy test with their yet-to-be-completed BioPen, which they say could eventually be in use everywhere from the battlefield to the veterinary lab. The pen uses a modified form of Enzyme-Linked Immunosorbent Assay (or ELISA) antigen detection to detect potentially harmful compounds, and can apparently also be used to determine if water is drinkable, along with ratting out environmental toxins, Ebola, Hepatitis B and C, Dengue, West Nile virus, and bird flu, among other nasty things. It works by taking a blood sample with a disposable tip, which is then automatically processed in the non-disposable cap, delivering the verdict in twenty minutes or less. Of course, they haven't actually gotten it into pen size yet -- for that, they're looking for one or two million dollars of funding -- but when/if it gets fully developed, they foresee the BioPen being a fairly affordable option, costing about $15 per test.
Researchers develop swimming, body-exploring robot
Researchers at Technion's Faculty of Mechanical Engineering in Israel look to finally be seeing some results from their crack Innerspace department, recently announcing that they've developed a pint-sized robot that can swim its way through heretofore inaccessible areas of the human body. The bot uses two tails to propel itself along, carrying a camera with it to document the picturesque journey -- eventually, the researches see the robot able to deliver medication straight to the source and even take biopsies. Of course, this isn't the first attempt to chart a course through your various bodily passages. Pill-based camera exploration has been around for a comparatively long time, but depends on your body's natural gastrointestinal movements to squeeze its way through your innards. More recently, scientists at Carnegie Mellon University developed a six-legged bugbot that can crawl through your intestines and be remotely controlled to ensure a thorough looksee. Technion's bot still looks to be quite a ways off from catching a ride in your spinal fluid, however, with the project's team leader estimating that it'll be a few years before they have a completed product.[Via Medgadget]
LouseBuster kills lice, is ineffective against Slimer, Gozer
We're sure Dan Aykroyd and the gang never envisioned their symbolic ghost-busting machine being converted into a lice-evicting device, but researchers at the University of Utah are doing just that. The "chemical-free, hairdryer-like device" -- dubbed the LouseBuster -- eradicates head lice infestations on children by exterminating the eggs (or "nits"), and killing enough lice to prevent them from reproducing. While the description may make some folks queasy, Dale Clayton not only supports the head vacuum, but claims that it cured his teenagers from their own battle with lice. The rake-like comb channels air from the machine into the hair, which after several half-hour treatments makes the environment too arid for lice to survive; however, the team was quick to warn parents that hairdryers weren't an acceptable substitute for the miracle-working powers put forth by the LouseBuster. Nevertheless, Clayton hopes his spinoff company, Larada Sciences, will have the presumably Bill Murray-approved apparatus on shelves soon.[Via MedGadget]
Artificial aid annoys user to counteract short-term memory loss
It's oftentimes tough to recall recent events, names, or gamertags while having a perfectly "normal" state of mind, but folks with brain damage, Alzheimer's disease, or ADHD are commonly plagued with the inability to bring back memories from just moments earlier. The function of the brain known as the "phonological loop" acts as a type of echo to hold snippets of pertinent information (such as phone numbers, directions, etc.) momentarily in your brain until you can get it written down; individuals suffering from short-term memory loss often lack this overlooked, but obviously critical, functionality. Daniel Bogen, a researcher at the University of Pennsylvania, has crafted a handheld device which acts as an aural stopgap to help people remember important information. The device boasts a speaker, microphone, and controls for recording / playback, and will automatically play reminders of the user's latest sound byte every two minutes, or if chosen, will nag its carrier to vocally repeat the message into the machine until he / she does so. To presumably prevent those amnesiac customers from perpetually misplacing their device, Bogen is considering integrating the hardware into "cellphones or wristwatches," but apparently forgot to mention when he hopes to see these in consumers' hands.
Matsushita Electric Works intros blood-toting HOSPI robot
Although Matsushita usually spends its toiling hours crafting gigantic televisions and ultrathin LCDs, the hard hat-wearing Matsushita Electric Works is busting out a blood-transporting robot to waltz the long, white halls in medical facilities everywhere. Designed specifically for "research institutes" which deal with blood inspections, the HOSPI droids are designed to work in groups which transport vials of blood from one workstation to another, while it "automatically analyzes" the containers on board. The self-proclaimed "sample conveyance robot" can wheel around at a blistering 2.2 mph to various destinations sans the need for tracks or human guidance, as it relies on programmable maps to understand the proper routes it should take. Sporting dual CPUs, the 'bot can presumably continue to operate (albeit less quickly) if one processor fails, and it also boasts the ability to dock itself in a recharge station if its battery is running low. Moreover, it sports a "highly precise laser radar" to avoid crashing into its blood-running brethren, walls, stray wheelchairs, and unmonitored patients. No word yet on how HOSPI reacts to EMMA's incessant requests for a date, however.[Via Digital World Tokyo]
NEC busts out "world's highest resolution" LCD
The leapfrog game played by manufacturers wanting to hold that oh-so-coveted "world's largest" claim has spread from megapixels to HDTVs, and now onto resolution. This time around, however, NEC is simply outdoing itself, as its latest 21.3-inch a-Si (amorphous silicon) LCD rocks an astounding 2,800 x 2,100 resolution. The previous "record" holder was NEC's NL256204AM15-01/01A, whose sesquipedalian model number was only trumped by its prodigious 2,560 x 2,048 pixel count. The panel also sports the company's own "super-fine TFT (SA-SFT)" technology, which enables a brightness of 1000 cd/m2 and a 1000:1 contrast ratio. If you're mulling over picking one of these up to really show off that kilowatt-burning quad SLI setup, you should probably know that this uber-fine monitor comes in monochrome only, as its sole purpose (for now) is to examine detailed medical imagery such as digitized X-rays. It's probably for the best, though, as we don't envision these black and white bad boys coming in cheap at any rate.[Via TGDaily]
Sony rolls out HD for the OR
Lest we forget, Sony does more than just Blu-ray and SXRD. At the American College of Surgeons Clinical Congress in Chicago it's showing off a collection of HD monitors and video equipment to make sure that when students go over your "minor surgery" gone horribly wrong, it is all recorded in crisp 1080i. Sony plans to show off the LMD-2140MD monitor shown here and its first XDCAM HD medical-grade 1080i video recorder, the PDW-70MD, with the IPELA videoconferencing platform to demonstrate high definition video streaming over IP. Some may question the need for high-def in medicine but we see this as an extremely necessary tool for training. Next time you make a trip out of the country for cheap surgery, make sure your fly by night quack surgeon earned his internet degree training in HD.
Mucus-riding robot headed to intestines
While the thought of having anything, much less a robot, crawl around and inspect our intestinal tract is certainly not in the forefront of our minds, Dimitra Dodou from Delft University of Technology in the Netherlands hopes her ideas will change the way colonoscopies are performed. Currently, uncomfortably large tubes or devices known as "wormbots" crawl through the delicate linings of your intestines, typically causing a great deal of discomfort in the process. Dodou's prototype contains a "polymer material" that clings to proteins found in the mucus lining of the gut, but can have its "sticky properties temporarily turned off" when sprayed with water. This two-faced material can be used in "snail-like" transporters that move by alternately gliding forward when it releases water, "sticking around" to control direction, and repeating again until the final destination is reached. By the close of 2006, Dodou hopes to have a camera-equipped version available for trial, which could be quite helpful in taking biopsies. Although we certainly don't intend on going under the knife anytime soon, it's quite comforting to know that Dodou's mucus-riding robot should makes things easier to stomach (ahem) if the occasion arises.
Augmented vision device may aid tunnel vision sufferers
As people age and develop ocular diseases such as glaucoma and retinitis pigmentosa, an unfortunate side effect is the gradual inability to locate and recognize objects not directly in front of them -- a condition more commonly known as tunnel vision. Previous gadgets designed to combat this problem, such as so-called reverse binocular glasses, have indeed been successful in providing patients with additional visual data; however, their miniaturizing effect took much of the detail away from peripheral objects, making them uncomfortable and ultimately ineffective for everyday use. Fortunately for tunnel vision sufferers, a new, higher-tech option may soon be available to aid them in their plight, in the form of an innovative device designed by a team at Harvard Medical School affiliate Schepens Eye Research Institute. Developed in conjunction with MyVu HMD manufacturer MicroOptical Corp., the augmented vision device consists of a video camera and transparent display attached to a pair of glasses and tethered by wire to a small computer. The computer processes the incoming visual data from the camera and projects a real-time outline of the wearer's surroundings right onto the center of the glasses, effectively "filling in the blanks" for the peripheral objects that would not normally be viewable. In tests conducted by the team, affected patients with only an hour of training were able to significantly increase the directness of their searches, while at the same time reducing the amount of time necessary to locate an object by about 22%. Further long term studies are necessary to determine how effective the device would be with more training and regular usage, but with such promising initial results, tunnel vision sufferers may finally be able to step out of the shadows and literally see the light.[Via Medgadget]
Modded Xbox rehabs stroke victims
How many stroke victims did the PS2 rehabilitate this week?:Engineers at Rutgers, The State University of New Jersey, have modified a popular home video game system to assist stroke patients with hand exercises, producing a technology costing less than $600 that may one day rival systems 10 times as expensive....Rutgers' low-cost hand rehabilitation system is based on the commercially available Microsoft Xbox video game and Essential Reality P5 gaming glove that detects finger and wrist motions to manipulate on-screen images. The engineers made minor modifications to the equipment and created software that delivers two types of finger flexing exercises needed to help recover hand functions in stroke patients.We should take up a collection of old Xboxes from people upgrading to 360 and donate them to this program. Xbox fanboys healing the sick. It's what we do.
