Physicists report that tiny worms can appear to “clean” their surroundings by sweeping particles into organized structures, even though the behavior does not require planning or intelligence. The work links that surprising order to the worms’ simple body motions interacting with grains and debris in their environment, suggesting that physics alone can generate tidy-looking patterns in living systems. Researchers say this kind of “order from motion” could help scientists understand how active, flexible filaments—living or synthetic—reshape messy environments at small scales.
Highlights:
- Multi-lab effort: The study was carried out by a collaboration spanning the University of Amsterdam, Georgia Tech, and Sorbonne Université/CNRS, highlighting how biology and physics teams are increasingly joining forces to study active matter.
- No thinking needed: A key takeaway emphasized in coverage is that the worms’ environmental organization emerges without deliberate decision-making—an example of how complex-looking outcomes can arise from simple rules.
- Active filament idea: Related coverage frames the worms as “active filaments,” a concept used in physics to describe flexible, self-driven structures that can transport and rearrange surrounding material as they move.
Perspectives:
- University of Amsterdam/Georgia Tech/Sorbonne Université-CNRS researchers: The apparent ‘sweeping’ and resulting environmental order can be explained by simple motion interacting with particles, rather than worm intelligence. (Phys.org)
