Shape-shifting active soft materials across evolution

Biological cells are inherently soft, active, and able to change their shape to fulfil their function —such as to move, divide, connect with partners, or exchange material. Today I will present our recent research on computational modelling of non-equilibrium physical processes that drive self-organisation and shape-shifting of subcellular structures across the tree of life. I will particularly focus on cell membrane reshaping driven by chemical exchanges with friends or foes within an ecological community. Then I will addres different solutions to cellular membrane designs across evolution, in particular those that support life in extreme environments and the diversity of life. I will finally discuss the assembly of filamentous cellular structures driven by chemical consumption. Beyond their biological context, our results can help guide the design of artificial structures that are able to mimic life at the nanoscale.
