It's a small small world- images of microscopic items
Nikon's Small World 2011Every year, Nikon hosts the Small World Photomicrography Competition, inviting photographers and scientists to submit images of all things visible under a microscope. The winners for this year's competition have just been announced, with Dr. Igor Siwanowicz taking first prize for his image of a common green lacewing larva that had earlier landed on his hand, trying to take a bite (photo number 21 below). This year's entries cover a fascinating range of subjects and sizes, from the eyes of a freshwater shrimp to the delicate scales on the wing of a butterfly, from a simple yet complex frost crystal to neurospheres and cancer cells. Enjoy a trip into a miniature world through the images shared here with us by the fine folks at Nikon, all from the 2011 Nikon Small World Photomicrography Competition. This image of an ant's head, viewed from the front (at 10X) took 11th place in the Nikon Small World Photomicrography Competition. The ant's autofluorescence was observed using confocal micrsocopy by Dr. Jan Michels of Christian-Albrechts-Universitat zu Kiel, in Kiel, Germany.
Dr. Douglas Clark of San Francisco, California submitted this image of the dried wing scales of a butterfly (Cethosia biblis) in incandescent light.
HeLa cancer cells viewed at 300x are seen in this 12th Place image by Thomas Deerinck from the National Center for Microscopy and Imaging Research in La Jolla, California. HeLa is an immortal cell line used in scientific research, made of cells originally sampled from cancer patient Henrietta Lacks in 1951.
The eye of a live giant waterflea (Leptodora kindtii), observed and submitted by Wim van Egmond of the Micropolitan Museum in Rotterdam, Netherlands.
Taking 4th place in the competition, Dr. Robin Young of the University of British Columbia in Vancouver, British Columbia used intrinsic fluorescence to observe this specimen of liverwort (Lepidozia reptans) at 20x.
