Non-Invasive Test Promises Rapid, Pain-Free Diagnoses Without The Use Of Fluorescent Dyes
Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as a traditional blood test in real-time, simply by shining a light through the skin. This optical instrument, no bigger than a breadbox, is able to provide high-resolution images of blood coursing through our veins without the need for harsh and short-lived fluorescent dyes...

Cancer's 'Field Effect' Enables Earlier Detection Of Pancreatic Cancer During Routine Endoscopy
By simply shining a tiny light within the small intestine, close to that organ's junction with the pancreas, physicians at Mayo Clinic's campus in Florida have been able to detect pancreatic cancer 100 percent of the time in a small study. The light, attached to a probe, measures changes in cells and blood vessels in the small intestine produced by a growing cancer in the adjoining pancreas. This minimally invasive technique, called Polarization Gating Spectroscopy, will now be tested in a much larger international clinical trial led by the Mayo Clinic researchers...
