Since 1974, Nikon has sponsored a yearly photo competition for images that delve into the worlds beyond the reach of the unaided human eye. The $3,000 first prize in Nikon’s 2007 Small World competition goes to Gloria Kwon of the Memorial Sloan-Kettering Institute in New York. Kwon’s composite image of a mouse embryo, captured in both visible and ultraviolet light, reveals the inherent biochemical differences between the embryo (fluorescent red) and its yolk sac (highlighter green).
The dozen images collected here (the top 10 images, plus two Wired News picks) capture facets of living organisms that have a technical meaning to the trained specialist, but appear to be pure art to the layperson.
