The Olympus BioScapes Digital Imaging Competition winners are currently on display at the New York Hall of Science. This competition, in its ninth year, is a dynamic international photo competition which honors the world's most extraordinary microscope images and videos of biological subjects. The Olympus BioScapes exhibit will be on display through August 31st. You can see the winners and many honorable mentions on the Olympus Bioscapes web site. --)

FIRST PLACE - Specimen: Rotifer Floscularia ringens feeding. Its rapidly beating cilia (hair-like structures) bring water-containing food to the rotifer. Technique:Differential interference contrast microscopy. (Charles Krebs/Issaquah, Washington, USA)

FIFTH PLACE - Specimen: Live coral Goniastrea sp., known as green brain coral. One full polyp in the center is shown with four surrounding polyps. Walled corallites are purple. Technique: Phase contrast illumination. (James H. Nicholson/NOAA/NOS/NCCOS/Fort Johnson Marine Resources Center/Charleston, South Carolina, USA) #
