Happy news about animals

OTTAWA — After staring into the eyes of chickens, a group of American researchers think they maybe on the path toward finding new ways to treat human blindness.
Researchers at the Washington University School of Medicine in St. Louis have discovered light receptors in a chicken’s eye allow the bird to see more colours than humans. The findings, published February in the scientific journal PLoS One, found receptor cells in a chicken’s retina are laid out in mosaic-like patterns, organized in a way that gives chickens, and other birds, more sensitive vision than most other mammals.
