Tiling patterns can be found thoughout the natural world - from honeycomb to fish scales. But now researchers have come up with a new way to create patterns in petri dishes - using bacteria. By engineering bacterial cells to express uniquely adhesive proteins on their surface, the team could create linear patterns - formed as colonies of cells stuck together when they grew. What's more, by varying the exact proteins expressed and modelling where to place the bacterial cells , they were able to control the resulting geometry - creating a range of complex patterns
