Microscopic beauty: Prize-winning photos

3rd place: Dr. Dylan Burnette's "Human bone cancer (osteosarcoma) showing actin filaments (purple), mitochondria (yellow), and DNA (blue) (63x)"

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.
