Future neural prosthetics could not only tap into brain signals, but also brain fluids, using the cerebrospinal medium to power a fuel cell. Researchers at MIT designed a new silicon wafer with several embedded fuel cells that generate power using glucose.

Researchers from University of Lausanne and EPFL University in Switzerland have developed genetically altered mice that have far higher physical endurance than regular mice. These "mighty mice" are able to run almost 50 percent further and for 20 minutes longer, while looking no different than their unaltered cousins, save for slightly larger muscles.
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.

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.
Glucose powers the cells in our bodies, and it may soon power the implantable devices we place in there as well. French researchers have implanted the first functioning glucose biofuel cell in living animals, generating electrical power from the glucose that exists naturally in the body.
Diabetics are saddled with the unenviable task of checking their blood sugar levels constantly, usually through a repeated ritual of pin-pricks and blood drawing. But a new non-invasive technology developed by a biochemical engineer at the University of Western Ontario lets diabetics keep tabs on their glucose levels with contact lenses that change colors as their blood sugar rises and falls.
