Watching cells work their proteins in real time - in color!

Oh my - this looks like it could open a new door to the study of biochemical processes inside cells. Very cool :^)

Campbell’s new technique, which he has dubbed FPX, uses genetically encoded fluorescent proteins to image dynamic biochemical events in live cells and tissues. The FPX method converts a change in protein–protein interactions into a dramatic green to red (or vice versa) colour change that is immediately visible.
