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.

You know those elephant-sized medical scanners? Totally amazing machines, sure, but things like that aren't apt to be shipped into obscure jungles throughout Africa. Thankfully, a team of researchers have developed something that could bring medical scanning to an even larger chunk of the world: a real live Tricorder. Of course, it's not really going by that moniker, but the diminutive scanner is able to interface with a cellphone via USB and utilize its 3G / WiFi access to send raw scan data to servers and receive images back. Granted, you won't get any high-resolution viewing from your average mobile, but it's certainly a step in the right direction.

Sending electrical shocks into the brain via a "brain pacemaker" has already led to dramatic breakthroughs like the revival of a man trapped in a vegetative state for six years, but new research may mean that the technique is soon a common treatment for disorders like depression and OCD. Researchers from the Cleveland Clinic, Mass General, Harvard Medical School and Brown Medical School implanted the Medtronics brain pacemaker into 17 people suffering from depression and tracked them for a year, finding significant improvements in mood as well as social and occupational functioning, while 26 patients suffering from OCD were followed for three years and also showed "marked improvement." Findings will be presented to the American Association of Neurological Surgeons this week in Chicago, and clinical trials are scheduled for later this year -- in other news, sales of "The Terminal Man" to neurosurgeons recently skyrocketed for unknown reasons.

Researchers at Osaka University are redefining "thought-controlled" limbs. Hailed as the first endeavor to dabble in the world of bionic phalanges by requiring open-skull surgery, the research is seeking to develop "real-time mind-controlled robotic limbs for the disabled." Of course, it's not the goal that's striking, but the means. Essentially, gurus working on the project are hoping to place electrode sheets directly on the surface of the brain in order to "obtain a more accurate signal," and amazingly enough, they're currently working to sign up willing subjects that are already scheduled to have brain electrodes added to deal with "monitoring epilepsy or other conditions." Maybe the bionic beings really aren't that far off, eh?

Gurus at Purdue University have conjured up a prototype device which, when injected into a tumor, can actually track the "precise dose of radiation received and locate the exact position [of the tumor] during treatment." Currently, the needle-sized device is held within a hermetically sealed glass capillary, contains a miniature radiation dosimeter, operates without batteries and instead relies on "electrical coils placed next to the patient" for activation. As small as the RFID-enabled unit is, engineers are still hoping to create a version that is around the size of a grain of rice, and hopes are to have it in clinical trials in 2010.

We'll go ahead and warn you: if you're hoping to purge your mind of all things science this weekend, this post isn't the one to be reading. For the rest of you knowledge seekers, Arizona State University researcher Wayne Frasch has developed a biosensing nanodevice that could possibly revolutionize health screenings and speed up that grueling airport security process. Put simply (well, as simply as possible), he discovered that the enzyme F1– ATPase can be equipped with an optical probe and "manipulated to emit a signal when it detects a single molecule of target DNA." Currently, a prototype of the DNA detector is already being worked up, but there's no word on when (or if) the device will escape the lab and hit the commercial realm. Still not geeked out? Hit the read link and hold on for dear life.

Shortly after hearing a sad tale of a 7-year old cancer patient having his medication and PSP stolen whilst en route to treatment comes yet another story of the world's meanest preying on the innocent. This go 'round, a group of griefers (which appear to be members of Anonymous) managed to invade a support forum established by the nonprofit Epilepsy Foundation and use JavaScript code and messages littered with flashing animations to effectively assault dozens of visitors who suffer from the disorder. The Foundation managed to catch wind of the problem within 12 hours of the attack, and while the boards were closed down temporarily to purge it of offending messages, many readers (such as RyAnne Fultz, pictured) experienced headaches and seizures before rescue arrived. Let's just say we sincerely hope the culprits get what's comin' to 'em.

Believe it or not, this actually isn't the first FDA approved personal hair remover we've come across, but for those looking for something capable of handling some seriously hairy ordeals, look no further than Silk'n. Created by Home Skinovations (har har), this unit relies on proprietary Home Pulsed Light technology to zap unwanted hair and bring back the smooth. Of course, this thing still has to be used "under the direction of a physician," but after waltzing into his / her office with three inches of sprawling chest hair blossoming from under that halfway buttoned shirt, we'd wager you'll have the requisite signature in no time.

Eye-controlled interfaces are far from revolutionary, but giving one of the world's most famous robotic surgeons the ability to interpret eye movements is most definitely a huge leap forward in the pursuit of making operations less invasive. Reportedly, British researchers have implemented new software into the Da Vinci robosurgeon in order to enable human surgeons to "sit at a viewing console directing the movement of the robot's mechanical arms inside the patient's body." Additionally, the program can track eye movements and "build up a 3D map of the area of tissue the surgeon is looking at," and it seems as if the developments could eventually be used on a variety of other ER-based robots. Just make sure your doctor chugs a couple of Red Bulls before putting you under -- wouldn't want those eyes wandering aimlessly, now would we? (Psst, "no-go zones" are included, thankfully.)

We've seen self-healing materials and artificial arms, but a team of researchers hailing from UCLA have taken two fabulous ideas and wed them together to create "an artificial muscle that heals itself and generates electricity." Put simply, the contracting / expanding of the material can generate a small electric current, which can be "captured and used to power another expansion or stored in a battery." The scientists have relied on carbon nanotubes as electrodes rather than metal-based films that typically fail after extended usage, and in an ideal world, the research could eventually lead to (more) walking robots and highly advanced prosthetics. Integrate an AC adapter in there and we're sold.

Considering the plethora of facilities that have opened just in the past few years to deal solely with individuals that have become undoubtedly addicted to video games, the internet and all things Hello Kitty (we jest, we jest), we're not surprised one iota to hear that uncontrollably texting / e-mailing could soon become "classified as an official brain illness." According to a writeup in the latest American Journal of Psychiatry, internet addiction is a common ailment "that should be added to psychiatry's official guidebook of mental disorders." More specifically, Dr. Jerald Block, a psychiatrist at the Oregon Health and Science University in Portland, even goes so far as to argue that said phenomenon (neglecting basic drives to spend more time online) be "included in the [next edition of] Diagnostic and Statistical Manual of Mental Disorders, psychiatry's official dictionary of mental illnesses." Until then, we wish you the best of luck convincing that creature living in your basement with a dedicated T1 line that he / she isn't alright.

We've seen initiatives all over the globe created in an attempt to beat blindness, but researchers based at MIT are feeling fairly confident that their development is within a few years of being able to "restore partial sight to people who have slowly gone blind because of degenerative diseases of the retina." The bio-electronic implant, which is about the size of a pencil eraser, would actually sit behind the retina at the back of the eyeball, and images would be transmitted to the brain "via a connector the width of a human hair." As it stands, an FDA grant application is already in the works, and the scientists are hoping to have it implanted in an animal as early as this summer. Still, the solution only works for folks who "were once able to see and have partially intact optic nerve cells" -- those who were blind from birth or suffer from glaucoma are unfortunately ineligible for the procedure.

Sure, we've seen brain power used to give mobility back to the immobile, but a new development in Europe is one-upping current efforts by adding in a hint of artificial intelligence to the tried and true brain-computer interface. The MAIA BCI not only converts signals emitted by the brain into actions -- such moving a wheelchair forward -- it also thinks for itself when needed in order to assist the user in getting where he / she wants to go. Essentially, the individual need only think about going left or forward (for example), and the machine itself will automatically detect obstacles and potential barriers in order to move more efficiently. As it stands, there's still quite a bit of testing to be done before MAIA-based wheelchairs would be available to the public, but researchers are already hoping to integrate said technology into artificial limbs and the like.

Sintex Industries' aptly-dubbed biogas digester is most certainly not the first of its kind, but it is somewhat commendable that its maker is making no bones about this thing's purpose. Destined to "solve India's energy and sanitation problems in one stroke," this concoction can convert "human [waste], cow dung, or kitchen garbage into fuel that can be used for cooking or generating electricity." Reportedly, a one-cubic-meter digester would sell for around $425, but could pay for itself in energy savings in under 24 months. Excrement to energy -- now there's a concept.

In-vitro fertilization may soon become much more effective, if a new device dubbed the "silicone womb" comes out of testing successfully. Currently test-tube embryos are developed in an incubator, but the .2-inch long silicone womb, produced by Anecova, allows them to be implanted inside the mother for up to four days, during which time they're exposed to the uterus through 360 40-micron holes. The goal is to develop stronger, more resilient embryos for eventual pregnancy, but a small test in Belgium has so far proven inconclusive as to the device's effectiveness -- and some researchers doubt it'll work at all, since the embryos will be located in the uterus rather than the fallopian tubes where they would naturally develop. Still, there's hope that the environment inside the uterus will be an effective substitute -- to quote one researcher, "it's a lot closer to a fallopian tube than a plastic tray." 40 women are signed up for testing starting today, but results aren't expected for some time.
