A future Apple Watch could be essential for diabetics
Apple is quietly developing a sensor that can monitor a person's blood sugar levels continuously and non-invasively. If successful, the technology will be integrated into a future version of the Apple Watch to help people with diabetes manage their condition. At least, that's the scuttlebutt being slung around by CNBC, which claims the project was set up by Steve Jobs before his death.
The Dexcom G5 lets diabetics track blood sugar on their phone
Keeping tabs on a body's glucose levels is a way of life for diabetics -- a ritual performed several times a day, often before or after meals. It's an essential chore, but it often requires special hardware for reading blood test strips or stand-alone receivers for patch-devices that read blood sugar levels under the skin. Thankfully, a better way is coming: the FDA recently approved an iOS-compatible glucose meter that can send constant updates directly to your phone.
Sanofi-Aventis debuts iBGStar blood glucose meter for iPhone
It's not the first to announce a blood glucose meter that connects to an iPhone, but Sanofi-Aventis has just rolled out what's surely the most streamlined solution to date. Unlike the LifeScan Bluetooth glucose meter shown off during Apple's iPhone OS 3.0 preview event way back in March of last year, this one connects directly to your iPhone (or iPod touch), and it can even be kept permanently attached with the aid of a custom (and fairly stylish) case. Otherwise, it functions just as you'd expect, with it able to display all the basic info on the device itself (it can also be used without the iPhone), and a ton more info on the accompanying app. No word on availability just yet -- that still hinges on FDA clearance -- but the device is "expected" to run somewhere in the neighborhood of $80.
Researchers receive grant to develop color-changing contacts for diabetics
Contact lenses that act as a glucose monitoring system for diabetics aren't exactly a new idea, but it looks like a group of researchers from the University of Western Ontario might be a bit closer to making them a reality, as they've now received a $200,000+ grant from the Canada Foundation for Innovation to further develop the technology. The secret to their contacts are some "extremely small" nanoparticles that are embedded in the hydrogel lenses which, like some similar systems (such as those pictured at right), react to the glucose molecules in tears and cause a chemical reaction that changes the color of the lenses -- thereby informing the wearer when their blood sugar is too low or too high. What's more, the reseachers say the same basic idea could also have a wide range of other applications beyond glucose monitoring -- for instance, being used in food packaging to indicate if the food is spoiled or contaminated.

Bayer introduces Contour USB glucose meter
We may not yet have nanosensors or high-tech contact lenses to monitor glucose levels, but there are still plenty of gadgets out there to help diabetics, and Bayer has now introduced another first with its new Contour USB glucose meter. While it doesn't go quite so far as to provide continuous, wireless monitoring like some similar concepts we've seen, it will accept test strips like any other glucose meter, and do plenty of things those others can't -- like store up to 2,000 readings on the stick itself, display the results right on the stick's color display, and sync up with your Mac or PC for more detailed logs and additional information. No firm word on an actual release date just yet, but Bayer says it will be available in the U.S. "soon."[Via Everything USB]
Oculus' uber-oxidised water hastens healing
We've seen self-assembling chips, self-healing panels, and even regenerative houses hit the drawing board before, but California-based Oculus has created a liquid that can reportedly quicken the healing process when recovering from wounds. The firm's Dermacyn topical wound care is an "oxychlorine formulation" using the company's own Microcyn concoction, which is made by "taking purified water and passing it through a semi-permeable sodium chloride membrane to produce the oxychlorine ions," and essentially contains "electrically charged molecules which pierce the cell walls of free-living microbes." The formula is reportedly successful in killing off virii, bacteria, and fungi, and currently, the company is enrolling patients in a Phase II trial to evaluate its effectiveness in treating diabetic foot infections. The company is hoping to start said trial in Q3 of this year, and if all goes well, wants to execute a pair of larger Phase III trials shortly thereafter.[Via BBC]
Researchers develop blood sugar-monitoring contacts
They're not the only ones working on contact lenses that measure blood sugar levels, but researchers at the University of Maryland's Biotechnology Institute led by Dr. Chris Geddes seem to have taken the technology further than most. They've reportedly developed special molecules that can detect glucose at very low levels which, when incorporated into a pair of contact lenses, should be adequate for detecting the amount of glucose in the wearer's tears -- which is about one tenth the amount in blood. What's more, unlike previous versions of the technology -- which required an additional device to read the results -- Geddes' new lenses will be able to simply display the results as a dot in the wearer's field of vision, changing colors to indicate low or high blood sugar levels. A lot more pleasant than the pin prick most diabetics now use to monitor their blood sugar to be sure, although as you can no doubt guess, more testing is needed before the lenses can be released into the wild.[Via Digg]
