Pack enough string-like objects together, and they will begin to align with one another. But replace the strings with worms ...

Cytoskeletal filaments propelled by surface-bound motor proteins can be viewed as active polymers, a class of active matter. When constraints are imposed on their movements, the propelled cytoskeletal ...

In a crowded room, we naturally move slower than in an empty space. Surprisingly, worms can show the exact opposite behavior: In an environment with randomly scattered obstacles, they tend to move ...

The fascinating patterns of collective motion created by autonomously driven particles have fuelled active-matter research for over two decades. So far, theoretical active-matter research has often ...
