'MasSpec Pen' could help distinguish between cancerous and healthy tissue during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur.

Developing imaging techniques for early detection of eye and brain diseases

The eyes may be the window to the soul, but to scientists, they are also the window to the brain. In particular, the retina, a delicate light-sensing neural network with specialized cells at the back of the eyeball, is linked directly to the brain via the optic nerve and is considered by some to be part of the brain itself.

Researchers create noninvasive technology that detects when nerve cells fire

Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells fire based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level.
