UCLA scientists eavesdrop on cellular conversations by making mice 'glow' with firefly protein

... the same kind of computer chip used in home video cameras to convert light into electrons. The team injected luciferase, the protein that makes fireflies glow, into cells, then injected the cells into the mouse. They saw a remarkable sight. Each time two specific proteins spoke with each other, it activated...
