For nearly four decades Nikon has been organizing its Small World microscope photography contest and this years’ entries are surely one of the best ever. 20 winning photographs were selected from nearly 2000 submissions for their originality, informational content and visual impact. The first place went to Jennifer Peters and Michael Taylor for showing the blood-brain barrier in a living zebrafish embryo, which Nikon believes is the first image ever to show the formation of this barrier in a live animal.
