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.

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.
iPhone and iPad are preferred by physicians says survey
Next time you visit your doctor and poke around his or her office, chances are you'll see an iPhone or an iPad lying around. A survey of 3,700 physicians by QuantiaMD reveals the iPad and the iPhone are the preferred mobile devices among those in the medical profession. According to the survey results, 83% of physicians own a smartphone. Of those with a smartphone, 59% have an iPhone and 29% have an iPad. About 44% of those physicians without a smartphone expect to buy one in 2011. What will they choose? 39% said they plan to buy an iPhone and 27% plan to buy an iPad. How does Android compare? Only 20% see an Android handset in their future, while a lowly 7% want an Android tablet. This dominance holds true whether the physician buys the device out-of-pocket or his practice funds the purchase. These iOS devices are certainly being put to good use. Doctors use them to look up drug information, choose a treatment path, learn about new treatments, help make a diagnosis and more. (Ed: Plus, come on -- would you really want someone who buys a Windows phone to be in charge of your health?)
iPads used for diagnosis and treatment in Texas hospital
You can add another hospital group to the list of those already using iPads in a medical setting. Texas Health Resources will be using Apple's magical and revolutionary tablet to help test patients' recovery, check the status of inpatients, and share and view medical records around the hospital. There's a whole strategy called mHealth built around mobile devices like the iPad in the company, and a recent survey of employees suggested that 40 percent of the doctors in facilities are already using iPads or another tablet. Texas Health is also running their own apps -- they have six up and running at the moment, with even more being tested and worked on. One reason the iPad is so helpful for them, they say, is that they allow doctors and nurses to stay mobile rather than sitting on a computer at a desk, which means more hands-on time with patients. Of course, that also means more IT workers to keep the mobile devices updated and running well, but apparently Texas Health is all over that one. It's good to see Apple's tablet being put to good use in health care facilities where it can really make a difference.
Startup's headset will bathe your brain in ultrasound, might help fight cancer, too
The scientific community has spent a decade exploring ultrasound as a means of breaking through the blood-brain barrier -- a layer of tightly-packed cells that surround the brain's blood vessels, making it difficult for doctors to deliver chemotherapy and other treatments to cancer patients. Thus far, though, most ultrasound-based techniques have relied upon complex and often costly equipment, including MRI machines and infusion pumps. But researchers at a startup called Perfusion Technology think they may have come up with a less invasive, more cost-effective alternative -- a new headset designed to deliver low-intensity ultrasound therapy to the entire brain over the course of extended treatment periods. This approach differs markedly from most other methods, which typically target smaller areas of the brain with high-intensity ultrasound doses. As with most other potential breakthroughs, however, Perfusion's technique still needs to undergo some major testing. The company has already conducted several tests on animals, but the last time a similar method was tried on humans, many subjects ended up suffering from excessive bleeding. And that doesn't sound good at all.
GumPack wearable vitals monitor: the new MedicAlert bracelet?
It may not have the charm or good looks of, say, the uBOT-5, but a new wearable vital signs monitor could cut back on doctor's visits for the chronically ill. Produced by a Kansas State University student, the GumPack -- known as such for its size -- is a multi-sensor monitoring device that fits in the palm of your hand and relays vital stats to your doctor via the internet. Along with a built-in camera and microphone for record keeping, as well as WiFi capabilities for connectivity, the battery-powered GumPack will sport various sensors, like a reflectance pulse oximeter or a two-thumb ECG. The monitor is still in the concept stage, and will likely not be available for mass-market distribution for years -- if ever -- but with technology like this in the works, the "I've fallen and I can't get up" lady might as well start looking for a new gig.
Sofie surgical robot gives haptic feedback for a more humane touch
Surgical procedures assisted by robots are nothing new -- they can be more precise and less invasive -- and now it looks like a new upgrade could make them even better. The main drawback of a surgical robot is that the human surgeon performing the operation gets no tactile feedback, but that's not the case with Sofie. Sofie, a joystick controlled robot gives haptic feedback to the surgeon by adjusting the resistance the controls give to indicate how much pressure is being exerted, surely a welcome addition to bots of this kind. This robot is also more compact than many earlier bots of this kind, and its creators are now looking to bring it into production, with a goal of it coming to the market in about five years.
BioWare's Ray Muzyka on how to make single-player gaming more social
The good folks at IncGamers had a chat with one of BioWare's founding medical doctors, Ray Muzyka, about the company's history of classic single-player gaming and its upcoming foray into the world of massively multiplayer with Star Wars: The Old Republic. Muzyka says that the line between solo and collective experiences is blurring: even traditionally single-player games are dipping into the vast realms of multiplayer co-op and competition through online social tools and downloadable content. Speaking specifically, he says that Dragon Age: Origins is a good example, with online social features for what is definitely a single-player experience. And Mass Effect 2, he says, will explore these ideas through its own DLC. In fact, he outright guarantees us that BioWare is "planning more [DLC] than in Mass Effect 1." As players who couldn't get enough of the two packs on offer for the original game, that's Muzyka to our ears.
Littmann Electronic Stethoscope lets docs record, analyze heart rhythm
We didn't even know there was such a thing as an "auscultation workflow" until we first encountered the FreedomScope, a Bluetooth-packing untethered stethoscope. The 3M Littmann Electronic Stethoscope also relies on Bluetooth for wireless communications, but its purpose is somewhat different. While it looks (and for the most part acts) just like a normal stethoscope, it also has noise canceling / sound augmenting technology alongside the ability to record heart and lung sounds, which may then be analyzed using the bundled Zargis StethAssist software. It's a bit on the pricey side at $379, but should be welcomed with open arms by collaborating diagnosticians and avant-garde concert bootleggers. [Via MSN Money; Thanks, Will]
J Allard to be Dr. J, but not the Dr. J you're thinking of
If no one else will volunteer, we'll be the ones to say it: We miss J Allard. If Microsoft ever needed a bald-by-choice, too-cool-for-the-room-as-long-as-that-room-is-at-E3 spokesperson, it's now. But if The Man in The Hoodie and Sports Coat is ever returned to us, we'll need to address him as Dr. J Allard, or Honorary Dr. J Allard, if you want to be a dick about it.Allard's alma mater Boston University will give him the degree (which is just as authentic as his image) on May 17 alongside Larry Bird and Steven Spielberg. Will Allard mark the event by performing a Triple Lindy into the nearby BU pool? We can dream.[Via Giant Bomb]
USB ultrasound device coming to a Windows Mobile phone near you?
Two computer science professors at Washington University in St. Louis have produced a USB ultrasound probe which is compatible with Windows Mobile smartphones. The project, funded by Microsoft, has developed and optimized probe that uses less power, and is enhanced for data transfer rates on cellphones. The devices could be especially useful in on-the-go situations -- for ambulances, emergencies, and for use by traveling medical staff. The makers also foresee that the device could positively effect medical practice in the developing world, where equipment and doctors can be scarce, and a small, but cellphone access is ever increasingly prevalent. We don't know when these might be commercially available, but they are hoping to sell them for around $500 -- significantly cheaper than many portable ultrasounds, which can cost almost $30,000.

Hospital puts Wii to use, surgeons praise it
We all know about the relationship between surgeons and the Wii. No, we don't mean Trauma Center, we mean real-life doctors using the tech behind the Wii to train them for surgery. This piece from ABC7 news in California shows one hospital where it's being put to work.Surgical resident, Jeff Henke, commented that "this does really help." He further added that it "prepares you to enter the operating room." Now, we may be a bit biased, but we're not surprised that the Wii is such a diverse system. it's used to doing what no video game console could in the past.[Via Codename Revolution]
3D mammograms increase breast cancer detection by 23 percent
Scientists have developed stereo mammograms -- breast X-rays taken with special cameras and at multiple angles -- that they say can help them increase detection of breast cancer by 23-percent while decreasing false alarms by 46-percent. By overlaying images taken at different angles or using 3D glasses, Researchers at the Mayo clining say they can now see behind dense tissue that would normally block potential problem areas. Since early detection is a key factor in beating breast cancer, this is an exciting new development.[Via Slashgear]
Wii used to hone surgeons' fine motor skills
Proving that children and the elderly are not the only groups seeing benefits from Nintendo's Wii, a study on a small group of surgeons who had practiced gaming with a modified controller showed them to achieve significantly more improvement on a standard simulator procedure than did a corresponding group of control subjects. Study author Kanav Kahol worked with Dr. Marshall Smith of the Banner Health hospital chain to build a special Wiimote attachment (read: broken golf club add on + laparoscopic probe) that eight surgical residents used to play Marble Mania and the full suite of Wii Play games. The gamers were then pitted against eight of their less-fortunate colleagues in a computer-simulated laparoscopic procedure, and managed to attain 48% higher scores, on average, than the non-gamers. Unfortunately, games involving broader motions such as tennis or boxing are said to be less suitable for this sort of training, make a total liar out of your doctor the next time you catch him "honing up on the latest techniques" by playing Wii Golf.[Image courtesy of The Wall Street Journal]
Study: A Wii bit of practice before surgery is good
The Wii isn't just a good rehab device for patients, it's apparently a good warm-up tool for surgeons as well. A study at the Banner Good Samaritan Medical Center claims that certain types of games are effective as a precision control prep before surgery. Surgeons who did an hour of gaming scored nearly 50% higher on tool control and overall performance in a virtual reality simulator. The Wii's Marble Mania was particularly effective due to the controlled movements necessary -- ironically, Trauma Center isn't mentioned at all. The researchers will present at the Medicine Meets Virtual Reality conference later in January.
Cellphone lights enable operation to proceed in blackout
Hearing that a cellphone saved someone's life isn't exactly surprising these days, but it was the manner in which a bundle of handsets enabled doctors to continue on in a recent operation that differentiated this one from the rest. Reportedly, the backup generators at the Policlinico Juan D. Peron hospital in Argentina failed to activate after the power went out whilst an appendix surgery was ongoing, but rather than panicking, a family member gathered up a number of phones in order to provide enough light for the surgeons and anesthetists to keep on keepin' on. According to the hospital director, the operation went on without proper lighting for no more than 20 minutes, but thanks to the beaming LCDs, the fellow under the knife came through just fine.[Via Switched, image courtesy of foto8]
Trauma Center: New Blood announced
var digg_url = 'http://digg.com/nintendo_wii/Trauma_Center_sequel_revealed_for_the_Wii_PICS'; Given Atlus' sales success with Trauma Center: Second Opinion, timing the remake to release with the Wii's launch, it's no surprise that the small publisher has readied a true sequel for the surgery sim. Trauma Center: New Blood introduces two young surgeons, Markus Vaughn and Valerie Blaylock, along with several exciting features: a cooperative mode, online leaderboards, and a 16:9 widescreen mode.

Addiction experts: Video games aren't an addiction
Apparently the doctors from the American Medical Association (AMA) who were looking to have video game addiction classified as a disease have backed away from their decision. They now recommend the American Psychiatric Association, who would have had the final word on the matter anyway, consider doing more research into the issue and possibly add the diagnosis to their revision of the DSM (Diagnostic and Statistical Manual of Mental Disorders) in 2012. The AMA doctors who believe video game addiction exists say it affects approximately 10% of players, but say more study is needed.."There is nothing here to suggest that this is a complex physiological disease state akin to alcoholism or other substance abuse disorders, and it doesn't get to have the word addiction attached to it," said Dr. Stuart Gitlow of the American Society of Addiction Medicine and Mt. Sinai School of Medicine in New York. But Dr. Thomas Allen of the Osler Medical Center says, "Working with this problem is no different than working with alcoholic patients. The same denial, the same rationalization, the same inability to give it up." But is that addiction, compulsion or just playing really bad games? That's the question.Dr. Louis Kraus who deals in child and adolescent psychiatry says it's not such cause-and-effect issue. He says certain kids just have a more "compulsive component" in what they do. Kinda sounds like the same argument about kids who play video games and kill. The AMA will make its final recommendation on the issue later this week.
