Men with type-1 diabetes might be able to grow new insulin cells from their own testicular tissue, according to a new study. Testicular treatment could even be safer and more effective than stem-cell therapies.
Medical device makers have been trying to come up with a better way for diabetics to measure their blood glucose levels for decades, but while a handful of promising methods have enjoyed measured success, the finger-pricking, blood-drawing glucose meter is still the most common tool for everyday use. But a new development in an old research pursuit at MIT may finally provide diabetics with a painless means of checking their sugar, by simply shining a light on their skin.
Diabetics may have yet another tool in their blood-sugar management arsenal -- an implantable, fluorescent blood-sugar monitor. It involves small hydrogel beads that vary the intensity of emitted light depending on glucose concentration. They're called Life Beans.
The system, developed at the University of Tokyo, could lead to implantable blood-glucose monitors, which could enable 24-7 monitoring of a diabetic's blood sugar without having to prick the skin or use an attachable pump.

A new, implantable sensor that wirelessly transmits blood-glucose data has the potential to completely change the way most diabetics control their disease.
The round device is just a bit smaller than a Double-Stuf Oreo -- about 1.5 inches wide and half an inch thick -- and would be implanted in a person's torso. It's hermetically sealed, with an integrated antenna that wirelessly transmits data, a long-lived battery, and a pair of sensors.
A team of Australian chemistry students have strengthened the chemical bonds of insulin to make it stable even at warm temperatures -- a breakthrough that could simplify diabetes management. The finding could shed light on how insulin works, and eventually lead to insulin pills, rather than injections or pumps.
People get tattoos for all kinds of reason, such as conveying their appreciation for Japanese calligraphy or to let others at the gym know their biceps are rugged like barbed wire. But a team of MIT researchers have found a higher calling for tattoo tech: using a nanoparticle ink to monitor glucose levels in the bloodstream.
A new diagnostic test developed by researchers at ETH Zurich can tell if a patient has Type I diabetes, but gone are the days of blood samples and lab work. The new nanotech sensor can tell instantly if a patient has diabetes or an associated complication called diabetic ketoacidosis by simply analyzing a sample of exhaled breath.
The battle to control type-1 diabetes in children could get a little easier -- as long as the kids keep playing with their Nintendos. Bayer Diabetes Care unveiled a new gadget Monday that aims to help kids manage their disease by tapping into their love for video games.
The DIDGET blood glucose meter connects to Nintendo DS and DS Lite gaming systems, awarding points for consistently testing blood sugar levels and meeting blood-glucose targets. Kids can use the points to unlock different levels in video games online and through their gaming systems.
It's no secret that obesity is a growing problem for Americans. Our kids are growing larger, our rates of diabetes and heart disease show no signs of retreating, and our military is worried that the next generation of warfighters will be too big and sluggish to get the job done. But Boston-based Gelesis has engineered a complex obesity solution that works by a simple mechanism: take a pill, become full, eat less.
The ability to reprogram the immune system is one of the most sought-after goals in medicine. Now researchers are closer than ever to pulling it off in patients with Type 1 diabetes, one of whom happens to be our correspondent

A sign rests on the windowsill in the office of Jeffrey Bluestone, director of the Immune Tolerance Network and the Diabetes Center at the University of California at San Francisco. Measuring nearly three feet across, it reads "Club Bluestone" in pink and blue neon. It's the sort of artifact you'd expect to find in a bar. But Bluestone is a world-renowned immunobiologist; his father-in-law had the sign made for him in the late 1980s when Bluestone was working long hours in his lab at the University of Chicago.
