Visualized: Nikon's Small World microscope photography contest winners

3D render? The latest submission to deviantART? No, that's a microscopic photo of the blood-brain barrier in a live zebrafish embryo taken by Dr. Jennifer Peters and Dr. Michael Taylor at 20X magnification, and it's the latest winner of Nikon's annual Small World Photomicrography Competition. Not surprisingly, the runners-up in the contest (drawn from some 2,000 submissions) are just as impressive -- hit the links below for a look at all of them. Those interested in having themselves featured next year (and taking home up to $3,000 in Nikon gear) have until April 30th to get their submissions in for the next competition.
