Cone Diagram

Caption: Researchers from Princeton University and Washington University in St. Louis report that the unusual arrangement of cells in a chicken's eye constitutes the first known biological occurrence of a potentially new state of matter known as "disordered hyperuniformity," which has been shown to have unique physical properties. These states have a "hidden order" that allows them to behave like crystal and liquid states of matter. They exhibit order over large distances and disorder over small distances. This diagram depicts the spatial distribution of the five types of light-sensitive cells known as cones in the chicken retina.
