Cooperation is a universal feature of complex systems, from the origins of life and microbiomes to societies. What universal patterns can be found in these systems? Here's our new @pnas.org paper. @jordipinero.bsky.social @artemyte.bsky.social @sfiscience.bsky.social www.pnas.org/doi/epdf/10....

At first glance, looks like a Gray–Scott reaction-diffusion

But it’s a fertilized starfish 🥚: proteins self-organizing into spiral waves across the membrane

Same dynamics seen in ❤️/🧠/🌊, even quantum fluids. Universality in action!

An amoeba with teeth. When building its shell, Netzelia corona selects sharp grains of quartz and positions them around its aperture with the tips pointing inward. I took a few closeups, yesterday. #ProtistsonSky #amoebae #peatlands #MEvoSky

While our bodies seem static, our cells are constantly changing shape or on the move during tissue homeostasis or wound repair & even more dramatically during embryonic development, during events like gastrulation. Defining how cellular machines mediate these events is a key task for our field 1/n
