In the beginning there was… what, exactly? Uncovering the origins of life is a notoriously difficult problem. When a researcher looks at a cell today, they sees the highly-polished end product of millennia of evolution-driven engineering. In today’s paper, David Zwicker, Rabea Seyboldt, and their colleagues construct a relatively simple theoretical model for how liquid droplets can behave in remarkably life-life ways.
Cells use tiny capsules called vesicles to uptake nutrients, to dump waste, and to communicate. They astonishingly alter the mechanics and size of these capsules that are made of very thin layers with an incredible efficacy and speed. But what are the key parameters that govern the formation of these vesicles?
