It may look like little more than a pegboard and a force meter at present, but the PRIME hand-strength measuring device has already won first place at the IShow innovation showcase. Its magic lies in the custom software loaded onto the appended PDA, which makes it possible to accurately and repeatably diagnose hand and wrist injuries that doctors currently test for by squeezing and prodding. The Rice University students responsible for the Peg Restrained Intrinsic Muscle Evaluator have applied for a patent and are planning to commercialize the device, so we'll be looking for it on the next episode of House.

You wouldn't expect GPS tech to have an impact on asthma research, but the University of Wisconsin-Madison's David Van Sickle says it will -- he's planning on tagging sufferers so he can learn when and where they reach for their inhalers. The data will hopefully make sorting out environmental triggers of the disease much easier -- it took scientists eight years to prove that soybean dust near the Barcelona harbor caused a massive asthma outbreak in the 80s, a timeline that might have been dramatically shorter if location information had been available from the start. The plan's still in the early stages, but would-be participants can sign up already -- let's just hope the tracker is slightly more attractive than Kogan's enormous watch unit.

Look, we want the next generation of robot doctors to be as competent as possible; after all, it's them that'll likely be taking care of us when our fingers lock up and our cranium-housed SSDs finally fail. That said, we can't help but be freaked completely out by Laerdal's latest and greatest patient simulator, the SimMan 3G. This almost-human can be programmed with various practice scenarios for to-be doctors to hone their skills on, and as any sophisticated mannequin should, this one is also wireless, self-contained and able to withstand four hours of surgery before conking out. We have no clue how many thousands this thing will set HOSA clubs around the nation back, but anything that bleeds, winks, and secretes shouldn't be something you "buy," anyway.

St. Jude Medical's announced that patients from Austria, Germany, and Greece are among the first to be implanted with Libra Deep Brain Stimulation (DBS) devices to alleviate the symptoms of advanced Parkinson's Disease. Specifically, it's able to reduce akinesia, rigidity, tremor, and motor complications associated with taking levodopa.The company's touting Libra and LibraXP as having the longest-lasting battery of any DBS in their class, meaning potentially less surgical procedures needed for for when they gotta be replaced. No word on when they'll be expanding use of the device, but we're sure it's coming.

Researchers at Monash University in Australia have developed a piezoelectric motor that's 0.25 mm wide, which they claim is 70% smaller than the smallest design out there. The Proteus motor, named after Fantastic Voyage's microscopic vessel, uses an E. coli-like flagellum to swim through the bloodstream. The goal is to one day have it power microbots that'll enter the body by injection to take photos, deliver medicine and eventually do surgery. According to lead scientist James Friend, escape would come from it returning to the point of entry or, should something break down, via a micro-catheter -- no tear ducts necessary this time.

According to the UK's Telegraph, mobile phones are responsible for yet another one of the great terrors of the 21st century: dermatitis. Apparently, "skin specialists" have discovered that certain metals used in cellphones are causing some users to suffer inflamed, reddened, dry, blistered, and cracked skin. Sounds awesome, right? It seems that about a third of heavy talkers are sensitive to nickel -- a substance commonly found in gadgets -- which can become irritating after repeated exposure. Says Brown University's Dr. Lionel Bercovitch, "Given the widespread use of cellphones, the presence of metal in the exterior casing of these phones and the high prevalence of nickel sensitization in the population, it is not surprising that cellphones can cause allergic contact dermatitis." There's probably little you can do to out-and-out escape the problem, so we suggest full face mask whenever a call needs to be made -- also, for dinner parties.

Neurosurgery with robotic assistance is getting pretty old hat nowadays, so it looks like scientists are trying to up the difficulty factor by keeping their patients awake -- a team of French doctors just completed the first successful removal of malignant brain tumor from a still-conscious patient, using a computerized laser and an MRI scanner to guide the probe. The fiber-optic laser was fed into the brain through a 3mm (.12 inch) hole in the patient's skull and guided via MRI to the tumor, where it fired for two minutes and completely destroyed the cancerous tissue. Once the tumor cells were dead, the cable was removed and the patient was allowed to return home -- all within a single day. That's pretty impressive, and it comes on the heels of 15 similar trials where five out six patients who underwent the total removal procedure were cancer-free nine months after surgery. The team says further research will cost an additional two million euros to progress, but if this technique works as well as they claim after peer review, we'd guess that money won't be hard to come by.

We're still a bit gun shy when it comes to surfing over to PEAK Surgical's website after watching that PlasmaBlade demonstration video, but a new release from the outfit affirms that said electrosurgery scalpel has just been approved for use by the US Food and Drug Administration. The "tissue dissection system," as it's so gruesomely called, has been given 501(k) clearance, meaning that PEAK can now market its tool for use in general surgery. So, anxious to camp out and be the first in the country to get sliced and diced by one of these? Bombard your local hospitals with phone calls starting next month.

Finally, a use for electrocution besides your own, twisted interests. A company in Arizona has created a bandaging system which uses electrically activated wound-dressings to heal injuries. Dubbed the CMB Antimicrobial Wound Dressing with PROSIT (or CMBAWDWP as we like to call it), the bandage works by utilizing a single-layer polyester fabric which can carry a low-level electrical charge when wet. Over a short period of time, the charge can greatly reduce bacteria and infections in the treatment area. Also, it's fun at parties.

Cheng Luo, an engineer from the University of Texas at Arlington, has created a self-propelled microboat based on the toy boats he played with as a child. When an object -- say, a toy boat -- floating on water has a drop of oil on it, the change in surface tension propels that object in the opposite direction. With this principle in mind, Luo has created a microboat that measures just millimeters, contains its own reservoir of isopropyl alcohol as a propellant, and cruises at around 30 cm per second. "But, why?" you ask. Luo explains that these tiny boats could be used to deliver drugs in blood vessels or even to diagnose and treat ailments. Sounds good to us -- wash one of these down with some self-healing goo and you could be all set. But before we go, try saying "toy boat" three times really fast.

We may already have spray-on bandages, but Arch Therapeutics has developed a nanostructured substance that they say stops bleeding almost instantly. Originally developed at MIT, the material is awaiting FDA approval and could make its way into operating rooms soon. The liquid is made up of amino acids that form peptides and cluster into long fibers when exposed to salty environments, like, say, a whole bunch of blood. The material isn't terribly new -- it was originally discovered in the 90s, but only recently during an experiment did researchers realize that it would be great for blood control. Shortly thereafter, people saw dollar signs and Arch Therapeutics was founded.

Okay, so we're not exactly doctors, but we couldn't help but be intrigued by PEAK Surgical's announcement today that its PlasmaBlade electrosurgery scalpel had completed preclinical testing with positive results. Unlike traditional electrosurgery tools like the bovie cutter, the PlasmaBlade operates at low temperatures, using pulsed plasma energy to cut tissue and control bleeding. Then, stupidly, we watched the video. Let's just say now that it no longer matters to us that surgeons using the PEAK PlasmaBlade produce "minimal collateral damage" to tissue and that bleeding was reduced. Sure, it's great for the surgeons, but our eyes? Not going to be the same.
