Together with experimental collaborators, Professor David Bruckner at the University of Basel, Switzerland, has discovered that cells possess a kind of memory: they can "remember" how they previously navigated such constrictions. This allows them to move more quickly and efficiently through complex tissues. /news/2025-08-mechanical-memory-clever-strategy-cells.html Cell & Microbiology Molecular & Computational biology Tue, 26 Aug 2025 14:40:03 EDT news675437810 For months, Sabrina Staples stared at a silicone chip no bigger than a postage stamp, trying to coax cells into doing something remarkable.
