Fruit fly's visual-system development

Fruit fly's visual-system development

Dr. W. Ryan Williamson from the Howard Hughes Medical Institute in Ashburn, Vir., captured this otherworldly image of a common fruit fly's visual system halfway through pupal development, showing the retina (in gold), photoreceptor axons (in blue), and the brain (in green) at 1,500x.

The image was awarded fourth place in the 2012 Nikon International Small World Photomicrography Competition.
