NanoPass needles set to vaccinate sans pain
Given the choice, even we'd take the pills over the vaccination, but a new Israeli startup is hoping to ease the fears so commonly associated with needles. NanoPass Technologies is working to develop its "proprietary intradermal drug delivery technology," which supposedly deliver injections without the painful side effects by actually not reaching the nerve endings of the skin. Based on MicroPyramids, which are manufactured by MEMS (Micro Electro Mechanical Systems), the pure silicone crystals are used in extremely diminutive microneedles for intradermal injections, and the tip of the device measures less than one-micrometer in diameter. The company touts its pain-free technology (sound familiar?) as a breakthrough that is "non-intimitdating," which should reduce the likelihood of fainting both youngsters (okay, and adults) face when dealing with needles, and is even said to be easier to administer. Unfortunately, we've got no good news proclaiming that these will be replacing intramuscular and subcutaneous methods later this week, but the $6.5 million in funding that the company has acquired should go pretty far is helping its cause.

Thanko's USB Mask circulates air, freaks out co-workers
Nah, USB-powered fans aren't anything special these days, but infusing a couple of 'em into a bizarre facial mask and marketing it to folks with allergies earns top marks in the outlandish department. Thanko, the folks who continually put the fun back into USB, is busting out yet another oddity that relies entirely on USB power and your willingness to suffer through public humiliation. The whirlwind mask purportedly circulates airs and filters the incoming flow in order to provide a constant stream of clean, "purified" air, which could actually be useful for secretaries or other cube-dwellers who are forced to inhale the same stale office air day after day. So if you've been having trouble breathing, and don't mind being tethered to your computer nor the constant whirring that'll surround your mouth, you can snag the USB Mask now for ¥2,480 ($21).[Via Engadget Japanese]
IWARD nursebot looks to clean hospitals, fend off intruders
We all know security gets a little heavy eyed when the wee hours of the morning roll around, and we highly doubt the janitorial staff is humming along at maximum efficiency when the residents are snoozing away, so implementing a robot to tackle both tasks seems quite practical. The IWARD project hopes to develop a "nursebot" that wears several hats, and can handle cleaning up spills, utilizing face and voice recognition technology to "communicate with patients and spot unauthorized visitors," and even working in "swarms" to distribute tasks between the robotic crew. Researchers are aiming to have a three bot prototype ready to rock by 2010, and want to integrate sensors and camera to avoid collisions whilst "traveling along high-speed lanes in the hospital corridors." Better steer grandma's wheelchair clear of the robotic raceway, eh?[Via TechieDiva]
Kodak envisions edible RFID tags for medical purposes, light snacks
If you're not down with wearing, handling, or implanting RFID chips on (or in) human beings, we presume you're fairly skeptical about consuming one. A recent patent application filed by Kodak envisions an edible RFID wafer that would ideally be used to monitor various aspects of a patient's health. The digestible tag would be covered in a substance that would slow the dissolving process enough to view certain aspects of one's innards, and furthermore, these tags could be surgically implanted into knees and joints in order to alert doctors when additional work should be performed. The tags could even be integrated into medicines in order to more accurately witness whether a rebellious patient has indeed swallowed his or her pills. So before you cry foul on voluntarily ingesting a (hopefully) dissolving RFID tag, just think of all the medical breakthroughs this could lead to -- or how traceable you'd eternally be if your gastric acid is weaker than usual.[Via NewScientistTech, thanks Matt]
Eli Lilly offering up undercover insulin pen to US
There's already a bevy of devices out there designed to keep track and manage one's diabetes and glucose levels, but Eli Lilly's innocuous pen-like injector looks to make the process of taking insulin a bit less invasive. The Huma-Pen Memoir resembles your average ink pen and shouldn't look too out of place holding it down in your tee's front pocket, but whenever you need a shot of insulin, it conveniently turns into an injector thanks to the hidden hypodermic needle encased within. The device also "allows the user to dial the amount of insulin they need to take," and keeps the dosage, date, and time of the previous 16 shots in order to keep diabetics from overdosing. Users should be able to utilize the same pen for "around three years," and after a needle is used, another is inserted and ready to go at the owners request. A few lucky participants have already received their pen here in the US, and while this nifty invention has been available across Europe for some time now, it will officially hit American retail shelves next week for around $45.[Via MedGadget]
WVU's Punchstat system intelligently halts boxing matches
The state of West Virginia seems to be on the "get fit" warpath, as not only did the public school system decide to expand and renew the Dance Dance Revolution program to get youngsters a-movin', but now WVU has developed a system that allows boxers to give it a go without, um, perishing. The Punchstat analysis system is a ringside computerized tool that is being honed to provide a realistic and objective method of determining when a boxing match should be halted. Researchers in Morgantown have performed a "computer-assisted video analysis" to compare a trio of professional matches where one of them led to a fighter's death; these results were further compared with over 4,000 other bouts previously scored with Punchstat, and it was stated that a "significant differences" were seen in fights that led to death. Most notably, fighters that died due to boxing faced around 23 punches per round (compared to the average of 9.4), and more "power punches" were withstood as well. But before scientists can accurately implement a "danger meter" of sorts into pay-per-view matchups, some critics insinuate that factors such as "fighter strength and the effects of the punches that connect" need to be considered before it can be entirely reliable, and it's even suggested that a tried and true accelerometer be installed on a fighter to calculate the force of a blow. Still, we're down with beating someone to a pulp for sport if everyone leaves without a life-threatening injury, but we'll probably take the pansy's way out and stick with Wii Boxing to carve our calories.[Via Physorg]
University of Rochester: Action games improve vision
Science Blog covers a University of Rochester study that says action videogames improve visual processing by 20 percent. A group of students played Unreal Tournament and another group played Tetris, which was selected because of its motor complexity but visual simplicity. After regular training with the respective games, the UT players more easily identified the orientation of a letter "T" among a jumble of other shapes in a crowding test. The Tetris group's responses didn't change.The study suggests that action games alter the way our minds process information even after playing; the researchers think that games could help combat certain visual disorders. We just hope that our improved ability to identify objects makes up for our blurred vision after marathon game nights.
Bionic armed woman regains sense of touch
Although Matsushita and Activelink have rolled out a rehabilitating robotic suit aimed at giving handicapped individuals their ability to maneuver their own body parts once again, it appears that Claudia Mitchell has regained her sense of movement using a slightly different apparatus. Touted as wearing the "world's first" bionic arm controlled by thought alone, she now has the ability to carry out simple, albeit quite critical tasks again such as cutting up food. Doctors have re-routed the nerve endings in her arm to "a patch of skin on her chest," essentially enabling her prosthetic arm to respond to her thoughts concerning movement. Furthermore, a recent study of her wrist, hand, and elbow functions revealed that she could perform tasks "four times quicker than with a conventional prosthesis," and the team hopes to install "touch sensors" on the artificial hand in order to allow for tactile feedback in the future. Claudia seems to be understandably thrilled with the results thus far, as it even allows her to accomplish tasks such as putting on makeup and feeding herself -- but we're slightly disappointed that she apparently hasn't given a round of Wii Sports a go to build up those oh-so-crucial hand-eye coordination skills, but we're sure that challenge is just around the bend.[Via Digg]
USB-powered Posture Reminder keeps slouching in check
Those kind, considerate folks over at Brando are continuing to look out for the chair-sitter's well-being, as the USB Posture Reminder ranks right up there with the USB drink chiller and USB hair trimmer as goods that any desk-strapped individual should keep nearby. This USB-powered device clips onto the top of your monitor's frame, but instead of enabling video chats, it keeps a constant eye on the distance of your forehead in relation to the screen. The VISOMATE uses an ultrasonic sensor to determine whether your eyes are too close (or not close enough) to your screen; if you see a blue light being emitted, you're doing just fine staying in the 35- to 60-centimeter range, but if you manage to slouch too close and break the 35-centimeter barrier, a flashing red light will alert you to your mistake. If blinking lights aren't enough to cause epileptic fits straighten you out, you can even turn a "Chime" function on to reinforce the severity of bad posture, and you can take the first step in correcting your atrocious leaning habit by plopping down $26 and vowing to actually install it when it arrives.[Via Uber-Review]
Researchers craft microscale robotic hand for surgeries
It's no surprise that humans are doing less and less of the dirty work while they simply control robotic creatures that are actually doing the internal repairs, but a UCLA researcher has devised a ridiculously tiny "microhand" to handle even the smallest surgery-related tasks. The hand, which is said to be a "feat of microscale mechanical systems (MEMS)," measures just one millimeter across when closed into a fist, features four "fingers" made of six silicon wafers each, and touts four gas-powered balloons acting as the muscles at the wafers' joints. As you may expect, the gas lines that run to the balloons inflate and deflate the joints, causing the fingers to grasp and release as needed. The primary purpose is to eventually use the technology in new forms of "minimally invasive surgery," and although the microhand is likely years away from practical use, they're already in cahoots with robotic firm to develop a "slightly larger" rendition with an onboard camera for live action video feeds.[Via MedGadget]
Sanyo massage chairs also detect lies?
Sure, there's quite a few ways to sniff out fibs for those who just can't "read" body language all that well, and there's certainly a entire market saturated with massage chairs that supposedly coax your muscles in return for a hefty sum of cash, but it looks like Sanyo's lineup of massage seats just might sport a hidden agenda. According to Sanyo's ever-descriptive website, its array of massage chairs sport "physical shape sensors, power recline, and GK roller technology" among other things, but the standout feature is the "stiffness detection sensor" that "locates areas of physical stiffness and gauges fatigue by changes in skin temperature, perspiration, and pulse." Interestingly enough, those three measurements are the things lie detection tools are made up of my friend, so if you've got the 1337 skills to wire up a massage chair to some swank analytical software, you could potentially extract just about any truth you ever wanted while the culprit simply enjoys the ride.[Via CNET]
Active gaming burns more calories, coordination still a concern
A recent Mayo Clinic study may indicate that kids burn significantly more calories while playing active games (e.g., Dance Dance Revolution Ultramix 2, Wii Sports) than while engaged in sit-down games. That this conclusion seems obvious is part of the problem.Parents may now be more content than ever to plop their kids in front of the TV if they perceive that a few hours of active gaming will substitute for necessary exercise. Even if kids, on average, burn twice as many calories while on the dancepad than while button-smashing a gamepad, they're still simply engaged in virtual activity. Wii Sports might be all the rage but "touching a virtual ball is not the same thing as catching a real ball," warns Active Healthy Kids Canada director of development Jennifer Cowie Bonne, "You need those types of [real life] fundamental skills to build a foundation for a lifelong involvement in other types of physical activity." You wouldn't want Junior to grow up throwing baseballs like a pansy, would you?
da Vinci robot creators being sued by Caltech
It's no secret that doctors ought to have a good bit of insurance on their side due to the flurry of medical malpractice (and similar) lawsuits that hit hospitals and surgeons everyday, but you know things are rough when robotic MDs get taken to court as well. Intuitive Surgical Inc., the creators of the da Vinci system for robotic surgery, has been sued by the California Institute of Technology, which claims that the system "infringes four patents held by the university." Obviously, Intuitive's CEO called the suit "outrageous and without merit," but the Pasadena school is nevertheless "seeking an injunction" and repayment for "damages." What's notable about the case, however, is where it was filed, as Tyler, Texas is quite a long ways from both institutions, but attorney's in the know have called the Lonestar State "a haven for patent pirates." Of course, there are rulings out there that are finally leaning the way of the tech firms at hand, suggesting that "obvious patent laws" should be relaxed somewhat, but it seems that even this probably won't mess with Texas. Nevertheless, let's just hope one of those lawyers doesn't end up under a (disgruntled) da Vinci knife one day.[Via RobotGossip]
Mayo Clinic prescribes active games
The Wii has been getting a lot of attention lately, mainly because of its different control mechanism. However, movement in gaming isn't a new concept, which hearkens to days such as the NES Power Pad. Now, exergaming is getting a supporter. The Mayo Clinic has released a report on the results of an exergaming study. Using a sedentary base, games that use a camera (such as EyeToy) and using a treadmill while gaming burned triple the amount of calories as sitting (five times over for more obese children); dance games registered the greatest calorie burn at six times the sitting rate. With this new study, Nintendo is likely to jump on and further promote the health benefits of playing the Wii. Pulling children away from video games is a difficult task these days. While the Wii will unlikely burn the fat like Dance Dance Revolution would, they can add a bit to the marketing pamphlet to say the Wii requires exercise (if used right) for something their kid would otherwise be vegetating to do. As if we needed any more reasons to buy a Wii. [Thanks, Ben]
Shocking study reveals that activity in gaming fights obesity
Providing a mighty blow to both "research studies" and the value of Ph.D degrees everywhere, the latest rubbish information to come flowing from the Mayo Clinic's research lab is as close to an insult to intelligence as you can get. While it may have been somewhat understood that television can act as a painkiller for children, and that wireless headsets actually don't improve driving safety, this obviousness of this one takes the literal cake. The study, which is proclaimed as the "first to scientifically measure the energy spent playing video games," proved that sitting around while gaming burned the same amount of energy as kicking back and watching the tube, but when engaged in a "camera-based activity" (Eye Toy?), the "energy expenditure tripled." It was also shown that walking on a treadmill while gaming it up also tripled the energy burned, but it showed a "fivefold increase for the mildly obese group" of participants. While these results may be miles away from shocking, the most depressing aspect of the entire study was the conclusion that the results were so awe-inspiring that "they warrant further studies in randomized trials." Now, who's paying for this hoopla again?[Thanks, Mike]
Samsung prepping RFID-enabled refrigerator
Sure, there's always that heated debate over whether or not RFID use in our everyday lives is beneficial or voyeuristic, but Samsung's forthcoming refrigerator most certainly falls in the former category. No, it doesn't sport a built-in LCD monitor, automatic thawing, pizza nook, or an invisibility cloak, but it does manage to keep a close on the amount of food remaining in your refrigerated containers. Moreover, this eagle-eyed fridge will purportedly be able to send a shopping list the owner's cellphone or directly to the supermarket when it detects your milk, juice, eggnog, or assortment of critical condiments are reaching dangerously low levels. As if this wasn't enough to lay down a pre-order, it will supposedly offer up recipes to users as well based on what's currently residing in your fridge. Of course, there's no (presumably lofty) pricetag attached to this pipedream just yet, but it is slated to hit retail floors "around 2008 or 2009," and maybe they'll enable it to physically visit the grocery store and shop for you in the meantime.[Via textually]
Does brain training really work?
NPR's Morning Edition takes a look at competing theories on the effects of mental exercise on staving off dementia and mental degradation in old age. While the piece doesn't deal specifically with video games, the implications for brain training games like Brain Age and Mind Quiz and even puzzle and adventure games are pretty apparent. The results are decidedly mixed. One study of nearly 3,000 elderly people showed that a few hours of directed mental exercise could show effects up to five years later, but the improvement was rather modest for most volunteers. Another researcher cited in the NPR report thinks that building a "cognitive reserve" of mental skills before old age is more effective than taking up Sudoku in your autumn years. And then there's genetics, which may play a more important role in the proceedings than a simple crossword puzzle. The final takeaway? While games and puzzles might be a good way to keep your brain in shape, don't consider them a sure-fire way to prevent Alzheimer's disease. And whatever you do, don't get too frustrated while you play -- research suggests that's avoiding stress and depression can help you maintain good mental health.
Handheld germ zapper uses nanotechnology to nix parasites
If you're the type who rocks latex gloves everywhere you go, or you're just tired of toting around that messy liquid hand sanitizer, Hammacher Schlemmer has your solution. Posing as a flip-phone wannabe, this handheld germ-eliminating light reportedly eradicates "99.99-percent of E-Coli, staphylococcus, salmonella, and germs that cause the flu and the common cold." Aside from resembling a bevy of Nokia handsets, the device purportedly utilizes "UV-C light and nanotechnology" in order to "disinfect workplace keyboards or telephones (or mice), as well as items in the home that sustain germ vitality such as toothbrushes and cutting boards." Notably, it must be held just so above the germ-infested area in order to sterilize it, but an internal timer signals when the process is complete. So while we aren't apt to load down our knapsacks anymore with something so petty, the highly susceptible out there can get their own portable germ-slaying handheld now for $79.95.[Via Slashgear]
LipoSonix aiming for non-invasive body sculpting
We're sure there's quite a few of you out there that have already vowed to make good use of that Nike+iPod kit you received this holiday season in order to shape up in 2007, but for those who just don't have the time (or adequate willpower), LipoSonix could help you fool everyone into thinking you actually kept your resolution. While liposuction has become frighteningly common here in the States, a Seattle-based medical device company is hoping to give folks a "less invasive" alternative to the messy methods currently used. Preferring the term "body sculpting," the company claims that its technology "works by focusing high-intensity ultrasound through the skin into precise locations within subcutaneous adipose tissue, which permanently disrupts the adipocytes without damaging the epidermis, dermis, or underlying tissues and organs." In short, a specially crafted ultrasound transducer can purportedly eliminate unwanted tissue quickly, causing "minimal downtime and bruising" to patients, and hopefully costing less than procedures done today. Although we can't promise this (admittedly bizarre) technology will be available by year's end, initial clinical testing has reportedly been quite successful, but until a few more guinea pigs have survived for an extended period of time, we'll be sticking with the tried and true "working out" method.
Battery-free pacemaker on the horizon
Having one surgery is plenty, and having some foreign object implanted in your being is really pushing things, but knowing you're going to be under the knife every ten years or so to get a new battery is just absurd. Thankfully, a group of researchers in the UK feel the same way, and are well on their way to developing a battery-free pacemaker. Reportedly, the device would use a microgenerator producing electricity every time the patient moves, effectively eliminating the need for an internal battery. The cost of the £1 million ($1.96 million) project is being shared by the Department of Trade and Industry and private companies, one being Zarlink Semiconductor who has a large role in the device's development. Other teams around the globe are also seeking to create such a unit, with ideas spanning from tiny generators that receive power from heat right onto "biological pacemakers" that would correct heart problems without the need for a mechanical device. While there's no estimate as to when these gizmos will even hit the testing and approval phase, it seems that things are moving along quite well, but we have to stop and wonder how well a pacemaker powered by motion will function when you, well, cease moving.[Via MedGadget]
