The video, by Gabriel Martins of University of Lisbon, is a sequence of virtual slices through the 23-millimeter-long specimen made up of more than 1,000 images.
Second place went to this video of the beating heart of a live two-day-old zebrafish embryo. The heart, captured by Michael Weber of Germany’s Max Planck institute of Cell Biology and Genetics, is only a tiny bit bigger than the diameter of a human hair. In the video, you can watch blood cells flow throw the heart.
The third place video is an incredible look inside of a living cell. This video by Lin Shao of the Howard Hughes Medical Institute shows mitochondria within the cell using a technique that combines various time points into a three-dimensional image.
