A simple mathematical model can account for lizard’s green-and-black pattern

Enlarge / The patterns of the ocellated lizard are predictable by a mathematical model with regard to phase transitions. (credit: UNIGE or Michel Milinkovitch) Zebras and tigers have stripes, cheetahs plus leopards have spots, and the ocellated lizard ( Timon lepidus ) boasts a labyrinthine pattern of black-and-green chains associated with scales. Now researchers from […]

Scientists create new class of “Turing patterns” in colonies of E. coli

Scientists have shown how a new class of Turing patterns work by using synthetic biology to create them from scratch in the lab. Shortly before his death, Alan Turing published a provocative paper outlining his theory for how complex, irregular patterns emerge in nature—his version of how the leopard got its spots. These so-called Turing […]
