The winners have been announced in the 43rd annual Nikon Small World Photomicrography Competition. The top prize went to an image by five scientists at the Netherlands Cancer Institute showing immortalized human skin cells (HaCaT keratinocytes) expressing fluorescently tagged keratin.
The image shown here won third place for Jean-Marc Babalian of Nantes, France. It shows a living Volvox algae releasing its daughter colonies, magnified 100 times, although you will be forgiven for recognizing it as Pac-Man. See all the winning images here.
