Study Finds 470-nm Blue-Light Traps Reveal Slime Mold Escapes via Fluid-Flow Mechanics

Summary
German and U.S. researchers found starving Physarum polycephalum escapes blue-light traps through mechanical fluid-flow processes, not brain-like control, offering a basis for its apparent decision-making.
In 470-nm light barriers, the slime mold sent out many short exploratory protrusions, then consistently broke out near each shape's longest axis rather than the shortest route.
The team said rhythmic peristaltic contractions reorganize the organism's mass and internal cytoplasmic streaming until a transport mode emerges that can build enough pressure for escape.
Published in PRX Life, the study suggests decentralized organisms can adapt to environmental constraints through body mechanics alone, informing research on non-neuronal intelligence.
