Alan Turing’s Patterns in Nature, and Beyond

Turing Patterns in 3-D

That markings on animals are produced by Turing systems of pigments is now generally accepted, but the origin of what appear to be Turing patterns in more complex settings — such as limb and tooth and lung development — is still debated.

A basic step towards proving the existence of these three-dimensional Turing patterns is demonstrating a three-dimensional pattern in the lab. In a paper published Feb. 11 in Science, researchers led by Brandeis University chemist Irving Epstein do precisely this.

The researchers set off a chemical reaction that creates Turing patterns in laboratory flasks, then used tomography — a form of imaging used to reconstruct three-dimensional images from thousands of two-dimensional snapshots — to picture them.

"It's an intellectual coup," said Epstein.
