Researchers at the Georgia Institute of Technology and India's National Center for Biological Sciences have found that yeast clusters, when grown beyond a certain size, spontaneously generate fluid flows powerful enough to ferry nutrients deep into their interior.

In the study, "Metabolically driven flows enable exponential growth in macroscopic multicellular yeast," published in Science Advances, the research team — which included Georgia Tech Ph.D. scholar Emma Bingham, Research Scientist G. Ozan Bozdag, Associate Professor William C. Ratcliff, and Associate Professor Peter Yunker — used experimental evolution to determine whether non-genetic physical processes can enable nutrient transport in multicellular yeast lacking evolved transport adaptations.
