Bacteria harness the lotus effect to protect themselves

Researchers have discovered that bacterial biofilms adapt their surface texture to repel water, similar to leaves. The structure of these biofilms is influenced by nutrient supply, with some behaving like lotus leaves and others like rose petals.
