See how beautiful the world can look through a microscope

A zebra fish “selfie,â€� a butterfly’s curly proboscis and the fangs of a centipede. Welcome to the beautiful — and sometimes strange — world of photomicrography.

Nikon Instruments has unveiled the winners of its annual Small World Contest. The images celebrate the intersection of art and science, revealing the amazing, minuscule details of the natural world.

The top image was created by Oscar Ruiz, who captured an extreme close-up of a 4-day-old zebra fish embryo. Ruiz studies facial development at the University of Texas MD Anderson Cancer Center, and he hopes zebra fish can help scientists learn how facial abnormalities, such as cleft lip and cleft palate, form in humans.

Ruiz developed innovative techniques for creating time-lapse images of the developing embryo’s face, which he uses to track the movement of facial cells as the fish grows. Knowing this can help pinpoint genetic mutations that give rise to facial deformities.

Other winning images captured magnified images of human neurons, mouse eye cells, intricately arranged microscopic zooplankton and the tiny scales of a butterfly’s wing. Although Nikon’s judges have already spoken, you can still vote for your favorite on the contest’s Facebook page.
