"Small World in Motion": Nikon contest winners
Nikon’s 2016 Small World in Motion digital video competition puts the spotlight on incredible microscopic moving images. The contest attracts entries from photographers and scientists all over the world.
William Gilpin, a Stanford Ph.D. student in physics, and his team won first place for this work, capturing “the complex and beautiful currents that a starfish larva creates around itself to capture food.”
Second place: Predatory ciliate
Charles Krebs, an experienced photomicrographer, took second place with this video of a Lacrymaria olor, or swan’s tear. This predatory ciliate is a group of protozoans characterized by their hair-like organelles called cilia.
“It illustrates the amazing diversity of life forms in the microscopic world,” Krebs said.
Third place: Flowering fungus
Dutch photographer Wim van Egmond captured the flowering of Aspergillus niger, a mold that typically grows on different types of fruit.
Dr. Philipp Keller, Kristin Branson, and Fernando Amat of the Howard Hughes Medical Institute in Virginia captured video of automated cell tracking in an entire developing zebrafish embryo.
Their work was one of 17 entries to receive an honorable mention from the Nikon contest judges.
