Caption: This slow-motion video depicts freezing in a cell pair during a rapid-cooling experiment. The cells, which are observed using a high-speed video cryomicroscope, each have a diameter of approximately 10 µm. The formation of ice inside each cell has the appearance of a wave that emanates from the cell-cell interface and traverses the cell interior within the span of a millisecond (shown slowed down by a factor of 400 in the video). In the cell pair shown in this video, the intracellular freezing events occurred at approximately °F.
