3-D Turing pattern formation in a chemical reaction system

In a report in this week’s issue of Science, Brandeis professor Irving Epstein, senior research associate Vladimir Vanag and postdoc Tamas Bansagi use tomographic methods, like those employed in a medical CAT scan, but using visible light in this case, to obtain the first three-dimensional images of Turing patterns. These patterns have been proposed as a mechanism for morphogenesis in living systems, perhaps offering an explanation for phenomena like “how the leopard gets its spots” or skeletal structure in developing limbs. .
