The winners of the third annual Small World in Motion Photomicrography Competition have been announced.
Dr Gabriel G Martins of The Instituto Gulbenkian de Ciencia, Lisbon, Portugal, was the overall winner for his 3D reconstruction of a quail embryo. Comprising more than 1 000 separate images, the video shows in startling clarity and detail the anatomy of the specimen.
Specifically, 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 embry (23 mm long) is possible.
Technique: Optical tomography, illuminated with a blue LED light (green fluorescence)
