Some things are seemingly uninteresting to the naked eye but when you dissect them and put them under a microscope, they become a thousand times more interesting.

Olympus BioScapes Digital Imaging Competition is a contest for microphotographs of things (still living and once living). Olympus, a company specializing in imaging and optics, holds this annual event and got together a panel of micropists to serve as judges. Each entry was judged for scientific contribution, aesthetic quality, and technical excellence. The winners for which was announced last December.

Anyway, the picture above got the first prize. Can you take a guess? It's a blown up picture of a mouse retina, under 550x magnification. The other winners include motor neurons, zinnia flower primordium, stamen of Mirabilis jalapa, a visualization of living animal T cells attacking target cells, slime mold, golden algae, proboscis of common housefly, gypsy flower, and pulmonary epithelial cells of a live bovine.

Can you tell which is which?
