Thanks, Ricard!

Haha, thank you!

A tantalizing prospect is that biology may exploit the propensity of active fluids to form networks for evolutionary advantage, for instance in organisms such as slime molds or some fungi that form networks to facilitate resource sharing.

It provides a basis for development of new techniques for tunable control of the structure/rheology of fluid mixtures. It may also be relevant to biological contexts such as spindle-shaped cells kneading a path through extracellular matrix or metastatic cancer cells invading healthy tissue.

The active fluid stretches and kneads itself into long, thin filaments to create a connected network and the network forms even when the active fluid is a small fraction of the mixture. It is dynamically stable, in the sense that it persists forever, while continuously remodeling itself.
