Certain groupings of bacteria or cellular tissues form systems that are called active fluids. These can flow spontaneously without having to be forced from the outside, since their components are able to generate forces and move autonomously. When the activity is high enough, the spontaneous flows become chaotic, like those observed in the turbulence of ordinary fluids. University of Barcelona (UB) researchers have identified universal laws in this turbulent behavior of active fluids. The results of their work have been published in the journal Physical Review X.
