Skin color patterns in animals arise from microscopic interactions among colored cells that obey equations, say investigators. Researchers report that a lizard acquires its adult skin color by changing the color of individual skin scales. The work shows that the 3-D geometry of the lizard's skin scales causes the Turing mechanism to transform into the von Neumann computing system. Continue Reading...
