The research showed that the metabolism of the yeast created fluid flows around them, which helped transport nutrients further than would be possible just by diffusion.

Using computer models, the study found that the Lyapunov exponent, a measure of chaos, scales with the Reynolds number in a specific manner, with a precise value.

Researchers from IISc, NCBS, ICTS, India, and Israel’s Weizmann Institute of Science, have successfully developed a model to explain the dynamics of collective systems that are motile at high density.
