How the leopard got its spots: Age-old question of how animals develop their patterns may have finally been solved - with the aid of British computer pioneer Alan Turing

From spotty leopards to stripy zebras, nature has no shortage of distinct patterns on animals and plants. Now, the age-old question of how these patterns developed may have finally been solved. Scientists have shown that the same physical process that helps remove dirt from laundry could play a role in how tropical fish get their colourful spots and stripes. For their study, the team at the University of Colorado Boulder drew on the groundbreaking work of British computer pioneer Alan Turing, dating back more than 70 years. They believe their findings could help develop new materials and even new drugs.
