Cells have to do an awful lot of tasks correctly and on time in a noisy and unpredictable environment. How do they do it? In this post, we look at one particular process, making proteins, and learn how cells operate away from thermodynamic equilibrium in order to make the right protein at the right time over and over again.
The difference between a bacterium and a whale are huge, and not just their size. However, there are hidden scaling laws underlying all living things. These scaling laws are found to be due to the fractal-like nutrient distribution systems. Here, we review how to derive the scaling law for metabolic rate with organism mass, illustrating its generality and ubiquity.
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.
