Biofilm Surface Topography

Caption

Sticky patches of bacteria called biofilms often form intricate, starburst-like patterns as they grow. Researchers at Princeton University combined expertise in molecular biology, mechanical engineering and mathematical modeling to unravel the physical processes underlying the biofilms' curious crinkles. The image shows the surface topography of a Vibrio cholerae biofilm after 40 hours of growth on 0.6% agar.
