English: Synchronized genetic oscillators. Simulation of 200 bacteria swimming randomly in a 100×100×100 micron volume with wrapping boundary conditions. Each bacterium uses a system of ODEs to model the essential dynamics of the repressilator gene regulatory network. All bacteria are initialized with random initial conditions, but quickly become synchronized due to AHL communication. The color of the bacteria corresponds to their internal level of lacI mRNA, with yellow representing a low and red a high level. AHL concentration within the environment is shown in blue.
