The Nikon International Small World photography contest shines a light on the very small. For decades, the contest has showcased the beauty of photomicrography -- photographs taken through a microscope. Out of 2,000 submissions, the contest chose twenty standouts to honor.
The first place photo went to Dr. Jennifer L. Peters and Dr. Michael R. Taylor for "The blood-brain barrier in a live zebrafish embryo (20x)".
