The plasmodium of the slime mold *Physarum polycephalum* is capable of finding the shortest path between two points in a labyrinth. By placing nutrient-rich agar blocks at the start and end points of a maze, the plasmodium forms a single thick pseudopodium that spans the minimum distance between the blocks. This process involves the contraction of pseudopodia at dead ends, leading to the formation of a single, thick tube that connects the food sources. The plasmodium's ability to solve this maze demonstrates a form of cellular computation, suggesting that cellular materials can exhibit primitive intelligence.The plasmodium of the slime mold *Physarum polycephalum* is capable of finding the shortest path between two points in a labyrinth.
