When a person's skin is burnt or otherwise injured, part of the body's healing process involves boosting oxygen levels in the damaged tissue. A new paint-on bandage indicates those levels, by glowing when exposed to bright light.

Researchers have discovered a way to improve regrowth of corneal tissue in the human eye using a molecule known as ABCB5 to act as an identifying marker for rare limbal stem cells. Transplants in mice using this technique have successfully grown fully-functional transparent corneas.

This February, we first heard about a "bionic pancreas" that could radically improve the lives of type 1 diabetics. At the time, multi-day trials involving groups of adult and adolescent patients were still yet to occur. Those trials have now taken place, and the results are definitely encouraging.

Not everyone's blood clots at the same rate. While that might seem like simply an interesting bit of trivia, it's anything but trivial to doctors performing operations or emergency procedures. Now, an optical device can provide them with the needed information within minutes.

X-ray machines are all large devices that can only image hard structures such as bone ... right? Well, no, not all of them. An experimental new system is small enough to be considered portable, doesn't expose patients to as much radiation, and can image soft tissues in minute detail.

A team of researchers have built an experimental bioengineered kidney that not only produce urines, but has been successfully transplanted into a rat.

Blue light has been used to kill potentially-lethal bacteria in the skin and soft tissues of lab mice.

Massachusetts General Hospital has developed a handheld diagnostic magnetic resonance spectrometer that can diagnose cancer with nearly 100 percent accuracy in an hour.

Scientists have created genetically-engineered cells that serve as the light source for a laser.
