A new framework maps the collective movement of starfish embryos as topological “flowscapes,” revealing circulating flows, irreversible pathways, and structural transitions that emerge as they self-organize. Read more in @physrevx: go.aps.org/4r3NH71

A coordinated flock doesn't always stay coordinated. When two groups follow conflicting rules — one aligning, the other antialigning — the flock can spontaneously rotate. But beyond a certain size, that coherent motion breaks down into chaos. Read more: go.aps.org/4hf71Lc

Two new papers show that chiral order in 2D nonreciprocal flocking systems breaks down past a specific length scale of chiral rotation, giving rise to spatiotemporal chaos akin to turbulence at larger scales. 🔗 go.aps.org/4xJ6fvX 🔗 go.aps.org/3UKzDDi
