New high-precision eye surgery robot helps doctors stay sharp
A researcher at the Netherland's Eindhoven University of Technology has invented a new type of eye surgery robot designed to steady the ophthalmologist's hands and minimize error -- always a good thing when it comes to having needles and knives near your peepers. Kind of like an Igor to a mad scientist, the robot is considered a "slave" to its "master" doctor, who controls the automaton's arms using two joysticks. The doctor is still in charge of the cuts, but the technology makes sure the MD jabs that needle in at the exact same entry point each time without shaking to minimize ocular marring. Another notable feature is the robot's ability to switch between tools quickly, ensuring that if this whole doctor thing doesn't work out, it'll at least have a job at Hibachi waiting.

FDA drafts Mobile Medical Applications document
There are all manner of medically-based uses for iOS devices (the iPad in particular) if you are a medical professional, so it was just a question of time before patients themselves got in on the act (brace yourself, we get all bureaucratic up ahead). According to the Juvenile Diabetes Research Foundation, the FDA has drafted a document titled Guidance for Industry and Food and Drug Administration Staff - Mobile Medical Applications which is a first pass at attempting some standardization and looking at regulating the data and communication requirements of apps like this (for example, having a glucose monitor that can sync readings to your iOS device). Particularly for a condition like diabetes, which requires tracking and (sometimes frequent) monitoring, it's very handy to have all that data available quickly and easily. Having an official stance, even in draft, is a big step forward. From the JDRF: Once the information is on a smartphone, diabetes management will become more discrete while at the same time opening up a world of opportunity. You could view glucose levels, determine insulin requirements and make dosing decisions, track your treatment, and share all of this information seamlessly with the people that help with and matter most to your care. You could send alerts and alarms automatically to parents or caregivers, and receive helpful advice when needed. If this is something you're in favor of, or better yet, could actually use, now's your chance to add your voice to the encouragement. Here's the catch: You only have until October 19th to have your say. You'll find feedback on the JDRF post that you can use as an example to work from. If you or someone you know could benefit from this, take a moment and fill out the comment form. Who knows? Your comment may be the one that puts it over the edge and turns this draft into reality.
MobiUS smartphone ultrasound hits the market two years too late for relevancy
Mobisante's MobiUS smartphone ultrasound system scored FDA approval back in February, a big step towards getting the product out the door. Now the brainchild of former Microsoft bigwig Dr. Sailesh Chutani is finally available to order, the only problem is that it's based around two-year-old tech. At the heart of the MobiUS system is a Toshiba TG01 (it of Windows Mobile 6.5 stock) a now hopelessly outdated handset. Still, the probe and phone together cost $7,495, just a tiny fraction of what traditional ultrasound systems cost. We're sure there are small clinics, especially in poor and remote parts of the world, that are already eyeing Dr. Chutani's solution and, if his company scores enough orders, he hopes to cut the price in half. Maybe they can put some of that money towards developing a system that works with smartphone platforms people actually use -- like Android and iOS. Check out the demo video after the break.
Researchers say nanorockets could deliver medicine quickly within the blood
Faster delivery is always better when it comes to pizza, Thai food and now... drugs? Doctors seem to think so as they're experimenting with a new method of delivering medicine to the bloodstream via tiny nanotubes powered by rocket fuel. By storing healing meds within the platinum-coated metal tubes, doctors have been able to propel the tiny vessels up to 200 times their own length per second -- faster than swimming bacteria. It works as such: by introducing a hydrogen peroxide/water solution, the platinum reacts, sending it zipping forward and catalyzing the peroxide into water and oxygen. The downside? Even though the fuel is only .25 percent peroxide, it's still slightly toxic -- so it looks like it's back to the drawing board until they can develop a safer alternative. Spiders, perhaps? Check out the video demonstration after the break.
Daily iPad App: Netter's Anatomy Atlas
Any medical student or professional will instantly recognize the name "Netter." Frank H. Netter was a physician and artist who drew over 500 plates, or individual medical illustrations, covering virtually every aspect of human anatomy. Netter's Atlas of Human Anatomy, the book, is a classic in the field of medical reference. It outshines Grey's Anatomy, not only in its depth and accuracy, but also because of the detail of the images (not to mention, they're in color). If you're a medical student, Netter's is a must. However, the biggest problem with Netter's Atlas of Human Anatomy, as with most medical reference books, is medical students might break their backs carrying the book around. It's a tome that weights close to ten pounds. The extra weight has now been alleviated however, thanks to Elsevier Health Sciences finally bringing Netter's Anatomy to the iPad. Netter's Anatomy Atlas for iPad offers users all the benefits of the book and more. Because it's an app and not an ebook, Netter's Anatomy Atlas offers interactivity that could never be obtained in paper format. You still get all 531 Netter plates, but the app also gives you the ability to bookmark individual plates, add notes to the plates, customize and toggle labels, and offers a search functionality that allows you to quickly find a plate by plate number or keyword. The app also features some cool extras, like an additional 40 Netter plates once you register the app. Though I'm glad Netter's is finally available on the iPad (my copy of the 4th edition is literally falling to pieces), there is one major drawback to Netter's Anatomy Atlas for iPad. In a baffling move, the app only works in landscape view. You can't look at the images in portrait orientation even though that's how they were drawn. This means you're scrolling a lot through some of the taller images. I imagine this landscape-only limitation will be addressed in a future update (at least, I hope it will be). Besides that landscape orientation problem, the rest of the app is solid and I highly recommend it for anyone in the medical field. Like the book, the iPad app isn't cheap. Netter's Anatomy Atlas for iPad costs US$89.99. But there is also a free sample version, Netter's Anatomy Atlas Free, for those of you who want to try out the app first. If you do buy the full app, be warned: because of all the highly detailed plates it takes up a whopping 1.35 GB of space on your iPad. %Gallery-134922%
Print your own blood vessels, no need for red toner
Barely 24 hours after we told you about printing your own bones, the franken-science continues with the announcement that blood vessels are next on the body-parts-you-can-print list. Unsurprisingly, you'll need more than just regular toner if you want to start printing your own at home, but pioneering work by application-oriented research organization Fraunhofer has claimed to have cracked it by adding some good old 'two-photon polymerization' into the mix -- yeah, obvious once you know. The added photon special sauce is what makes the printed synthetic tubes biofunctionalized, which in turn enables living body cells to dock onto them -- we're guessing that's important. Sounds cute, but how long until we can start printing whole people -- Weird Science, anyone?
Brain scanner app lets you show off your smarts on-the-go
Forget learning how to open a champagne bottle with a saber, because this smartphone brain scanner probably has it beat for coolest party trick ever. After you pull out that 14-channel EEG headset you have lying around, all you need to do is attach the probes to your date's dome piece to measure his or her neural activity on your Nokia N900. The app then goes to work, taking binary data and reconstructing it on screen in 3D. The result? A new way to elimi-date Match.com candidates based on the real-time image of his or her melon. We can't promise it'll get you a second date, but we can give you a glimpse of the app in action after the break. [Thanks, arek]
IBM's Watson set to tackle health insurance, takes 'Diagnosis for $1,000'
After tackling your tech support woes, the famed Watson is moving on to mop up the health insurance industry. That's right, the IBM showstopper we all know and love for trouncing trivia kings on Jeopardy has been hired by one of the largest health insurance company's in the US. WellPoint Inc. will make use of the system's breakneck speed and healthcare database alongside patient records -- allowing the supercomputer to guide treatment options and prescribe medicines. Once implemented, data will be combined from three sources in a matter of seconds: a patient's chart / records from a doctor, the insurance company's patient history and the medical knowledge that Watson already possesses. A pilot program will roll out next year to a number of cancer facilities, academic medical centers and oncology practices. No word yet on when The Watson School of Medicine will start accepting applications.
Scientists develop blood swimming 'microspiders' to heal injuries, deliver drugs
Scientists at Penn State would like to release tiny spiders into your blood -- no, it's not the premise for a new horror movie, but rather, it's a medical breakthrough. The spider-like machines are less than a micrometer wide (just so you know, a red blood cell is around six to ten micrometers), and are designed to travel through veins delivering drugs and a little TLC to damaged areas -- not a totally new concept, per se, but even minor advancements can open up all sorts of new doors for troubled patients. Made of half gold, half silica, these microspiders are self-propelled by a molecule called the Grubbs catalyst, which scientists can control directionally using chemicals. Although still in the preliminary phases, lead researcher Ayusman Sen hopes to one day attach the creepy crawlers to nanobots, which could maneuver through the body to detect tumors, helping the immune system and scrubbing vessels clean of plaque. Not like that's doing anything to diffuse your arachnophobia, but hey...
Scientists develop the world's smallest single-molecule electric motor
Bigger is certainly not better when it comes to the world's first single-molecule electric engine, which measures in at one nanometer wide -- for perspective, that lash hanging from your left eye is around 60,000 times larger. Single-molecule engines have been used for years, but the new method uses a low-temperature scanning tunneling microscope to power and control the molecule more effectively. In the future, scientists could use the technology for things like lab-on-a-chip devices, miniature medical testing equipment that require a motor to push fluid through tiny pipes. Tufts researchers responsible for the discovery warn that a practical application is still a ways off, but are hopeful that they'll snag a Guinness world record, regardless. After hearing the news, both Pinky and The Brain are feeling entirely more confident about their lifelong goals.
UCLA creates portable microscope that uses holograms, not lenses
Instead of lugging a heavy microscope into the field, doctors and nurses in remote regions may have a more portable choice -- a lightweight microscope that replaces lenses with holograms. Researchers at UCLA announced a prototype dual-mode microscope that's lightweight, costs between $50 and $100 to produce and is similar in size to a banana. Like a hologram that uses interfering rays to create an image, this device shines light on a sample where its sensor chip (apparently also found in iPhones and BlackBerrys) and a cloud-based software program analyze the interference pattern and reconstruct an image of the sample. Since it's dual-mode, both large samples and small samples can be analyzed through processes called "transmission" and "reflection," and doctors could potentially use their laptops or smartphones to access the images remotely. Although still considered a prototype, researchers think the development has the opportunity to revolutionize health care by allowing doctors to test things like water, blood and food.

Eyeborg filmmaker fires up eye-cam to document cutting edge prosthetics (video)
In late 2008 filmmaker Rob Spence, caught our attention when he announced his plan to jam a video camera in his skull to replace an eye he lost to an unfortunate accident. Instead of connecting the camera to his brain, Spence sought to become a so-called "lifecaster," recording the feed on an external device. Now his bionic eye is up and running, and he's even partnered with a little company called Square Enix to create a documentary about state-of-the-art prosthetics and cybernetics. The short film, embedded after the break, was commissioned to celebrate the launch of Deus Ex: Human Revolution. But, this isn't just some over-long commercial for a game, it's a serious exploration of cutting-edge leg, arm, and eye replacement technology. Check it out below, but be warned -- there are a few images that might not sit well with weaker stomachs.
iTriage 3.0 adds live wait times for acute care facilities, medicine information and more
When TUAW last talked with the folks behind iTriage, it was shortly before World Health Day in 2010, and the app had just updated to version 2.0 with a version for Android. A little more than 16 months later, iTriage has hit version 3.0 with a plethora of changes and new features such as: Expanded disease treatment support where people can select a symptom and find the right doctor based on the symptom, care facility or prescription. Mapped medications where you can select a problem, such as a cough or cold, find the cause, then peruse medications and possible treatments. More than 1,000 common prescriptions and over-the-counter medications are listed to date. Search for urgent care facilities and see live wait times for acute care. Pre-registration and appointments rolled out. Updated interface adding improved provider search and access to key nationwide emergency hotlines and 911. Dr. Peter Hudson, one of the app's creators, told me that more than 700 hospitals, 400 urgent care clinics and 14,000 doctors are providing data for iTriage, and the number is growing. While I was hard-pressed to find participating physicans and hospitals in the Harrisburg area, I got a good glimpse of the new features by switching the location to Denver. Several of the hospitals listed live wait times for both pediatric and regular emergency care. One had the appointment/pre-registration list deployed. Check out these new features in the gallery below. %Gallery-131117% The app is extremely well-regarded, and it's easy to see why. I'm still feeling my way around central Pennsylvania, and it's nice to see where a hospital or pharmacy is close to me should I need it. "We're trying to make it really simple for people," Hudson said. The app is closing in on 3 million downloads spanning both iOS and Android, Hudson said. What'e more, 60 percent of those who have downloaded the app keep it on their mobile device, which Hudson said is 18 times higher than the average app retention. Future plans include additional functionality for consumers to connect with health care providers and with people in the same area who have suffered like injuries. iTriage 3.0 is a free download in the App Store.
EES packs circuits into temporary tattoos, makes medical diagnostics fashionable
Flexible circuit pioneer John Rogers and his team are at it again. This time he's developing a wearable, ultra-thin circuit that attaches to your skin just like a temporary tattoo. The Epidermal Electronic System (EES) consists of circuits which could contain electrodes capable of measuring brain, heart and muscle activity in the same way an EEG does now, transmitting this data wirelessly to your doctor. Because it's flexible and bonds to the skin, it can be worn for extended periods, unlike traditional diagnostic pads used in hospitals today. In the lab, the devices were solar-powered with embedded photovoltaic cells -- heavier duty circuits would require inductive charging to be practical. Rogers' team also looked into the tech acting as a game controller (they wired it up to someone's throat and played Sokoban with voice commands, still managing to yield a 90 percent accuracy rate), but it's some way off from replacing your SIXAXIS. One of the problems encountered concerned RF communication -- perhaps they should get on the horn to their friends in Oregon and build those fashionable diagnostic pants we're eagerly waiting for.
Robot skin captures super detailed 3D surface images
Remember those awesome pin art toys where you could press your hand (or face) into the pins to leaving a lasting impression? Researchers at MIT have taken the idea one (or two) steps further with "GelSight," a hunk of synthetic rubber that creates a detailed computer visualized image of whatever surface you press it against. It works as such: push the reflective side of the gummy against an object (they chose a chicken feather and a $20 bill) and the camera on the other end will capture a 3-D image of the microscopic surface structure. Originally designed as robot "skin," researchers realized the tool could be used in applications from criminal forensics (think bullets and fingerprints) to dermatology. The Coke can-sized machine is so sensitive, it can capture surface subtleties as small as one by two micrometer in surface -- finally solving the mystery of who stole the cookies from the cookie jar. (Hint: we know it was you Velvet Sledgehammer).
Tiny RFID amulet stores medical records, makes paramedics' lives easier
Using RFID to store medical records, ultimately making the jobs of paramedics and doctors that much easier, is hardly a new concept. But, for the most part, such devices have been limited to clinical trials. Asahi Kasei Corp. is hoping to change that with the debut of a tiny, 3cm-square charm that can be read by a computer or smartphone. In addition to basic info, such as name, birth date, and blood type, the chip could transmit links to more storage-intensive data like X-rays images. Instead of building out a proprietary system, the company is relying on established technology called FeliCa from Sony. That means the device will enjoy broad compatibility with existing products, and should be inexpensive to produce. Asahi Kasei hopes to begin selling the medical amulets to cities and hospitals within a year, for as little as ¥2,000 (around $25).
$1 chip tests for HIV in 15 minutes flat, fits in your wallet
Getting tested for STDs used to mean a doctor's visit, vials of blood, and days, weeks, or even months of anxiously waiting for results. mChip aims to change all that, while simultaneously ridding your brain of viable excuses not to get tested. It works as such: one drop of blood goes on the microfluidics-based optical chip, 15 minutes pass, and boom, the AmEx-sized device will confirm whether or not you have syphilis and / or HIV. The bantam gizmo is practically foolproof, as reading the results doesn't require any human interpretation whatsoever. Plus, it's cheap -- cheaper than a coffee at Starbucks. One dollar cheap. Researchers at Columbia University claim the mChip has a 100 percent detection rate, although there's a four to six percent chance of getting a false positive -- a stat similar to traditional lab tests. As you'd likely expect, there's hope that the inexpensive mChip will help testing efforts in places like Africa to detect HIV before it turns into AIDS. Next stop: the self-service pharmacy at CVS?
RIBA-II healthcare robot now stronger, smarter -- still a bear
RIKEN's original RIBA healthcare robot was already fairly adept at lifting patients while not completely terrifying them but, as is the case with such things, it's now been succeeded by a new and improved model. While its outward, bear-like appearance hasn't changed, the new bot boasts a series of upgrades that now lets it bend over and lift patients up directly off the floor, not just off a bed or wheelchair. It's also now able to lift patients that weight up to 176 pounds (41 pounds more than before), and it packs an array of new sensors that let it more accurately gauge a person's weight and carry them more comfortably -- not to mention some touchscreen controls on its back for when it needs a bit of direction.

iPhone 4 turned into a microscope via CellScope attachment
CellScope is a UC Berkeley project designed to enable microscopic image captures from a cell phone's camera. At first it might sound like a pointlessly geeky project to do microscopy on a cell phone, but in fact it has important applications for mobile health services in remote areas. In some areas of sub-Saharan Africa and other developing areas of the world, access to health care of any kind is scarce, and it often falls upon poorly-equipped doctors or volunteers to take up the slack. Since health care equipment is generally expensive to begin with, outfitting even a low-power microscope with a wireless transmitter capable of communicating with doctors at a remote location could easily run into the thousands of dollars. Not only that, but the equipment itself would likely be bulky, temperamental, and easily damaged. That's where CellScope comes in. Via an attachment, CellScope can turn a standard cell phone camera into a 5x to 50x microscope, essentially creating a miniaturized blood lab that can capture images and transmit them far more cheaply than traditional equipment. The iPhone 4 pictured above (courtesy of Scott Silverman) isn't the first mobile phone to be hooked into the CellScope rig, but with its high-quality camera and extensive photo sharing abilities, it might end up being the best mobile device for the job. Plus, viewing microscopic images on a Retina Display sounds like a great alternative to peering into one of those microscope eyepieces. This obviously won't replace traditional setups in a fully-equipped laboratory, but for the kind of remote and rural applications that CellScope covers, it sounds like an ideal solution.
Scientists find less damaging defibrillation method, heart tissue relieved
Good news, aging Earthlings: a team of researchers have found a way to shock a coding patient's heart, while leaving other organs and tissues undamaged from the defibrillator. The device send a single high voltage pulse of electrical energy to a patient's chest in order to fix an irregular or nonexistent heart beat; traditionally, what often results is damage to point of contact and surrounding skin cells, muscles and tissues, but a team of whiz kids have seemingly figured out a way to dodge the dreadfulness. Led by scientists Stefan Luther and Flavio Fenton, the team claims that by using a series of five pulses of less potent shocks (instead of a single concentrated charge), docs can see an 84 percent reduction in damaging power. This new technology -- coined low-energy antifibrillation pacing (LEAP) -- can also be used in implanted defibrillators, not just the well-known flappy paddles. Due to the relatively low emissions, both the patient and such implants have extended lives. And that, friends, is good for us all -- given the impending Robot Apocalypse, we'll be needing those extra years just to hold down the fort.
