Wired News - Biolaser Lights Up Stem Cells:
"Scientists have developed a laser that could illuminate stem cells in greater detail than ever, revealing the important steps they take to become neuron, heart or other types of cells.
Stem cells are unformed, and have the ability to become many cells in the human body, which is why scientists believe they could lead to powerful therapies. But the steps stem cells take to establish various identities are poorly understood. Researchers at Sandia National Laboratories in New Mexico say their 'biocavity laser' could elucidate those processes."
