"An unusual arrangement of particles has been discovered in the cells of chicken eyes. It's the first time scientists have seen such a system in a biological system — one that allows materials to behave like both a crystal and a liquid.
The unique arrangement is called "disordered hyperuniformity," and it could help researchers design advanced materials, such as optics that can transmit light with the efficiency of a crystal and the flexibility of a liquid.
When matter is organized into states of disordered hyperuniformity, it exhibits order over large distances and disorder over small distances. At one level, it's like a crystal that greatly suppresses differences in the density of particles across large spatial distances. But at another scale, it's liquid-like in that it exhibits similar physical properties in all directions."
Yes I saw that but with my advanced bird watching skills I know thats not a chicken .... probably .

My favourate Crow family story is the one about Ravens stealing fish by pulling up the lines the fishermen use to catch fish under frozen rivers and lakes in Norway.

Ooh, and according to Wikki, all birds have four types of photoreceptor, not just chickens. As do fish, amphibians and reptiles. I wonder if they have disordered hyperuniform retinas too?
