Dormant spores can count (VIDEO) University of California - San Diego This video is under embargo. Please login to access this video. Caption A microscopy time-lapse movie depicts the color-coded electrochemical potential value overlaid on top of the phase image of a single spore. As revealed by the phase image, the spore remains dormant while exhibiting the ability to count stimuli, as indicated by the multicolor-coded flashes of electrochemical potential changes.
