This image taken by Dorit Hockman of a skeleton of a short tailed fruit bat embryo beautifully illustrates the details of the elongated hand bones that form the scaffold of the bat wing. This x-ray-like image took months to prepare, with the sample preparation being done by Dr. Vanessa Chong-Morrison at the Marine Biological Laboratory in Woods Hole, Massachusetts. The sample took months of waiting for the specimen to be clear enough to reveal the bones, upon which the task of capturing this image began. It was a composite of images taken at high magnification and stitched together to the final image on display.

Dr. Jan Michels works in the field of functional morphology and biomechanics focusing on the study of morphology, material composition and properties of arthropod exoskeleton structures. He is also an accomplished imaging authority with recognition in top honors at Nikon Small World 11 times since 2007. His latest installment, that of a silica wall of a marine diatom (taken with confocal) shows stunning three dimensional detail seldom, if ever, seen of this type of organism. It looks a lot like a shower drain!
