When these centimeter-long worms are placed in a Petri dish containing fine sand particles, they naturally begin sweeping the particles into neat, compact piles. This remarkable behavior, it turns out, has nothing to do with intelligence. It&#8217;s all about physics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A team of researchers from the University of Amsterdam, Georgia Tech, and Sorbonne Universit\u00e9 found that the worms&#8217; natural wiggling motion and their flexible bodies are sufficient to create this cleaning effect. &#8220;Their activity and flexibility alone are enough to collect particles and reshape their environment,&#8221; said Saad Bhamla, one of the study&#8217;s leaders.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To prove this, the team built simple, &#8220;brainless&#8221; robots made of rubber links that mimicked the worms&#8217; movement. These robots, which had no sensors or programming, were able to do the same thing: they wiggled around and, in the process, swept all the nearby particles into tidy clusters. Computer simulations confirmed the same result.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This discovery has some exciting implications. On the one hand, it helps us understand how simple organisms can have a significant impact on their habitats, such as how earthworms aerate the soil. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the other hand, it could inspire a new generation of soft robots that can clean up the environment without requiring complex AI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Imagine a swarm of these simple, wiggling robots being released into a river to collect microplastics, or used to sort materials in a factory. They would just move around, and order would naturally emerge from the chaos. This &#8220;brainless&#8221; approach could be a cheap and effective way to tackle some of our biggest environmental and industrial challenges.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Points Scientists have discovered that some small aquatic worms have a surprising talent: they can clean their own environment.
