Patterns are ubiquitous in nature, but how do they form? By considering how proteins can interact with each other, Alan Turing gives an explanation of how patterns can be formed without any genetic control, simply by following known laws of physics.
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.
