Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

... A nano-thin layering of gallium aluminum arsenide combinations send up numerous tiny beams from a small cross-sectional generating area. These beams are reinforced or thwarted by the position and density of the mitochondria. "The pictures we get from normal and cancer cells are very different," says Gourley. "M...
