AMO Arm pneumatic prosthetic does mind-control on the cheap

We’re no strangers to amputees moving stuff with their minds — for that matter, a thought-controlled prosthetic isn’t really new to us, either — but the pneumatic arm you see here isn’t like other intelligent limbs. Unlike most mind-operated prosthesis, the Artificial Muscle-Operated (AMO) Arm doesn’t require invasive surgery, and according to its inventors, it costs a quarter of the price to make. Here’s how the thing works: the host human wears a headset that sends brain signals to a chip in the arm that then matches those signals to a database of related actions, triggering a series of pneumatic pumps and valves to move the limb. Thus, if the wearer thinks ‘up,’ the arm moves up. The AMO Arm’s creators, a pair of undergraduate biomed students, say that not only is their invention a steal to produce, but it also takes just minutes to acclimate to, which has us wondering, do you have to be missing an arm to get a hold of one of these things? You know, we can always use an extra hand. Full PR after the break.

Lasers let deaf ears pick up what the sonic world is putting down

Not going to front: we’ve a soft spot in our heart for focused beams of light. We’ve seen ’em rid the world of its space junk and set the pace of human hearts, and now, they’re taking a leading role in aural advancement. As improbable as it sounds, a research team from the University of Utah led by Richard Rabbitt has found that lasers may be able to give deaf people the ability to hear. Using a low-power infrared diode — similar to those in laser-pointers tormenting cats the world over — Professor Rabbitt found that exposing oyster toadfish hair cells (analogous to the cells found in humans’ inner ears) to infrared light caused them to release neurotransmitters and activate adjacent neurons. This could lead to laser-based ear implants able to stimulate focused areas of cells with thousands of sound wavelengths, as opposed to today’s electrode implants whose electrical current spreads through human tissue and limits the deliverable sonic range. Smaller, more efficient power supplies and light sources are needed before optical hearing aids become a reality, but if these newfangled lasers ever get their act together, we should be able to hear version two (and three) coming down the pike.

BrainGate hits 1,000 day mind-control milestone, nearly three years of pointing and clicking

Aspiring Svengalis rejoice! For BrainGate has reached a significant landmark in computational thought-control — the 4 x 4-mm implantable chip has given a woman with tetraplegia the ability to point and click with her brain for 1,000 days. An article recently published in the Journal of Neural Engineering said the woman, known simply as S3, performed two easy tasks every 24 hours, using her mind to manipulate a cursor with 90 percent accuracy. Each day she was monitored, S3 would post up in front of a computer and continuously command the thing with her thoughts for 10 minutes. Functionality reportedly deteriorated over time, but the paper points to the chip’s durability, not sensor-brain incompatibility, as the culprit. Research is currently underway to incorporate BrainGate into advanced prosthetics that could get tetraplegics like S3 up and moving again. Now, how’s that for the power of positive thinking?

Columbia doctors turn to IBM’s Watson for patient diagnosis, clairvoyance

Who says Watson’s only good for laying the smack down on former Jeopardy champions? In what can only be described as the natural progression of things, Herbert Chase — professor of clinical medicine in Columbia’s Department of Biomedical Informatics — is working with IBM in order to retrofit the supercomputer to “help doctors diagnose and treat patients.” According to Chase, this level of robot practice has been impossible for the past score or so, and if the experiment works, Watson could serve to provide physicians “immediate, accurate answers to unusual, head-scratching questions that come up in their daily practice and do so based not only on the latest published research, but also the blogosphere.” In other words, Watson could rapidly collect and analyze up-to-date published data from a near limitless amount of online sources, and then use that knowledge to recommend suggestions that a seasoned M.D. may never consider. Furthermore, Chase sees tremendous potential for Watson in the realm of personalized medicine; considering that two patients with the same diagnosis won’t necessarily react to treatments the same way, Watson could come up with alternatives on the fly. There’s no clear indication of when the testing will wrap up, but see how far you get next time you’re in the emergency room by inquiring about Dr. Watson’s availability.

NeuroFocus makes first wireless EEG sensor headset, don’t call it a thinking cap

It’s well known that advertisers track our web-surfing habits to tailor the ads we see, but they’d prefer to know exactly what’s going on inside of that brain of yours. NeuroFocus’ aptly named Mynd, a full-brain wireless EEG sensor headset, serves as a stylish and easy way to record your thoughts whilst gazing at logos and lusting after products. In addition to neuromarketing applications, the European Tools for Brain-Computer Interaction consortium (TOBI) see it as a tool to help develop new technology for those with neurological disabilities. Sporting looks straight off the Game Grid, the Mynd is made of medical-grade EEG sensors to capture brain activity 2,000 times per second and a Bluetooth radio to shoot your thoughts to the smartphone, tablet, or PC of your choice. The wireless bit represents a huge upgrade over traditional EEG caps because it makes the headset’s mind-reading powers available in shopping malls and living rooms instead of just hospitals. All so the sellers of things can know just how effective a spokesperson the ETrade baby really is. PR’s after the break.

Scientists separate plasma from blood with working biochip

Disposable biotech sensors won’t let you diagnose your own diseases quite yet, but we’ve taken the first step — a research team spanning three universities has successfully prototyped a lab-on-a-chip. Called the Self-powered Integrated Microfluidic Blood Analysis System (or SIMBAS for short, thankfully), the device takes a single drop of blood and separates the cells from the plasma. There’s no electricity, mechanics or chemical reactions needed here, just the work of gravity to pull the fluid through the tiny trenches and grooves, and it can take as little as ten minutes to produce a useful result. It’s just the first of a projected series of devices to make malady detection fast, affordable and portable. Diagram after the break!

Kinect keeps surgeons on task, Nintendo 3DS might assist optometrists with diagnoses

The latest generation of gaming gadgets do some nifty tricks, and one of the niftiest they might perform is assisting the realm of medicine. Microsoft’s Kinect sounded like a candidate for surgery, and this month real-life surgeons have actually put it to use — Sunnybrook Hospital in Toronto, Canada rigged the Xbox 360 depth camera to its medical imaging computer. Now, doctors don’t have to scrub out to manipulate an MRI scan, or even appoint a peon to the task — rather, they simply raise their bloodied glove, and dive into the digital imagery with a wave of a dextrous hand.

Meanwhile, the American Optometric Association has expanded upon its initial praise of Nintendo’s 3DS, saying the autostereoscopic 3D handheld “could be a godsend for identifying kids under 6 who need vision therapy.” Though Nintendo’s warning labels had originally incited a bit of fear among parents, the organization says that kids who can’t experience the 3DS to its full potential may have amblyopia (or other vision disorders) that can be more easily treated the earlier it’s caught, though one doctor interviewed by the Associated Press contends that kids with amblyopia may not know what they’re missing to begin with — so don’t necessarily expect a panacea, folks.

Dutch researchers dust off X-ray machine from 1896 to compare it to modern equipment

This one is a bit shocking to us. X-rays were discovered in 1896, and recently, a team of researchers at Maastricht University Medical Center in the Netherlands pulled a machine from 1896 off the shelf for the purpose of comparing its results to modern equipment. The researchers say that this original equipment pumped out around 1,500 times more radiation than new equipment in order to produce its results. Speaking of those results, they are unsurprisingly less sharp and detailed than modern X-rays, but they still look pretty impressive if you ask us. The X-rays were conducted on a cadaver this time around rather than a living person because of the high levels of radiation. Full results will be published in the Journal Radiology this month.

SoundBite dental hearing aid receives European approval

We’ve already seen the principle of bone conduction be applied to headphones, but Sonitus Medical is taking the idea to a whole new level with its SoundBite dental hearing aid, which has just received the necessary European CE Mark certification (it already has FDA approval). As you can probably surmise, the device is a hearing aid that’s placed on your teeth, although it’s not actually implanted or attached in any way — it’s simply custom fitted to the person’s upper back teeth. The other part of the package is a more standard-type hearing aid unit that’s worn behind the ear, which processes and wirelessly transmits to the device in your mouth. That’s obviously not intended for cases when a simple hearing aid will do, but Sonitus says the system can help people who are “essentially deaf” in one ear regain their spatial hearing ability.

Researchers create microscopic disposable camera to see up in your guts

It’s true, a team of researchers have created a one-cubic-millimeter throwaway camera, and if they have their way, it could be peeking inside you in the next year. The new tiny shooters, which sport a 250 x 250 pixel resolution, are created using a streamlined process in which the lens and sensor wafers are affixed before being cut into a series of 28,000 little cameras — eliminating the need to mount and wire each one individually. This new mode of production cuts back on cost significantly, allowing physicians to throw away the little guys after routing around in your intestines. According to the camera’s creators, their diminutive invention could make its way into your doctor’s office as early as 2012.
