The winners of The EMBO Journal Cover Contest 2012 are Martin Oeggerli for best scientific image and Eric Röttinger for best non-scientific image.

An image showing a water-repellent network on the surface of a mosquito egg (from Culex pipiens) won the scientific category. "Mosquito eggs are as much revolutionary as they are evolutionary - they are so fascinating, you think you must be dreaming," says science photographer Oeggerli.

The highest scores in the non-scientific category were for an image of a bivalve mollusc that swims by clapping its shells together.
