Google teams up with GSK to develop 'bioelectronic medicines'
By forcing startups like Google X, Fiber and Nest to behave like companies and take financial accountability, Alphabet believes that its subsidiaries are more likely to invest in projects that will ultimately make it money. Being in the expensive healthcare business, Verily -- formerly Google Life Sciences -- often needs to speculate to accumulate, but for its latest venture, the company is dreaming big. It's teaming up with British pharmaceutical giant GlaxoSmithKline (GSK) to develop bioelectronic medicines that can "harness electrical signals in the body to treat chronic disease."
Electronic neural bridge helps paralyzed mice walk again, human application might prove tricky
It's only been a week since we heard about age reversal in mice, yet already we've got another big advancement in rodent medical care: a solution for ameliorating the devastating effects of spinal cord injuries. A UCLA research team has shown off a new system that can restore walking motion to a mouse's hind legs, but not only that, it also grants control to the little fella by responding to its front legs' actions. Electromyography sensors detect when a mouse starts to walk up front, triggering electronic signals to be sent to the functional lower portion of its spine, which in turn starts up the rear muscles for a steady walking gait. It's only been tested on a treadmill so far, but the result seems to be a seamless restoration of walking capacity in rodents that doesn't require any outside assistance. The same will be pretty hard to replicate in humans, bipeds that they are, but that's why it's called research and not reobvious.
Flexible, implantable LEDs look set to start a new body modification craze
LED lights are cool, you're cool, why not combine the two, right? We doubt that's quite the reasoning that led to this international research project, but it's certainly an appealing way to look at it. Our old buddy John Rogers from the University of Illinois at Urbana-Champaign has headed up a research team with participants from the US, China, Korea, and Singapore, who have together produced and demonstrated a new flexible and implantable LED array. Bettering previous efforts at inserting lights under the human skin, this approach allows for stretching and twisting by as much as 75 percent, while the whole substrate is encased in thin silicon rubber making it waterproof. Basically, it's a green light to subdermal illumination, which could aid such things as monitoring the healing of wounds, activating light-sensitive drug delivery, spectroscopy, and even robotics. By which we're guessing they mean our robot overlords will be able to color-code us more easily. Yeah, that must be it.
NC State researchers uncover muscle mimicking fibers
While some researchers over in Raleigh are having fun tinkering with PlayStation 3 farms and dodging the RIAA, NC State's Drs. Tushar Ghosh and John Muth are occupied building prototypes with fibers they say "resemble human muscle and can exhibit muscle-like capabilities when electrical currents are applied." The duo sees the development as paving the way for "advancements and potential applications in robotics, smart textiles, prosthetics, and biomedicines," as they have reportedly found that polyurethane and silicone tube structures shaped like human muscle strands can be manipulated with electricity. It was noted, however, that the current models are using strands "roughly the size of a pencil lead," but the next step is to scale down the fibers and integrate them into a robotic Mr. and Mrs. Wuf.
New system warns of potential bone fractures
While ultrasonic stimulation may now be an FDA approved method of healing bone injuries, a team of researchers at Purdue University and the University of Toledo have developed a prototype system that will hopefully keep you from requiring such treatment. The group is designing a wearable device that alerts a person engaged in rigorous activities (read: Dance Dance Revolution contests) when a stress fracture is immanent so they can cool their jets before it's too late. The system records "acoustic emission data" (sound waves creates by tiny bone fissures) the same way a machine monitors the integrity of bridges to detect harmful amounts of pressure before disaster strikes, and the data can be quickly analyzed via PDA software to determine if you're pushing things beyond recommended limits. The same techniques used in measuring earthquakes will potentially be used on athletes, runners, dancers, soldiers, and even horses in order to mitigate those oh-so-troublesome hairline cracks. While we don't intend for this to discourage you from remaining faithful to that newly-devised exercise plan, at least you would have an excuse to quit know when enough's enough, as you definitely don't want to end up hospitalized under this RN's care.[Via MedGadget]
