This 3D reconstruction of a quail embryo – comprised of more than 1,000 separate images – shows in startling clarity and detail the anatomy of the specimen. The winning video shows a sequence of “virtual” slices through the whole embryo with 10 days of (in egg) gestation. With this technique, studying the whole anatomy of large specimens like this embryo (23mm long) is possible.
