🌿 A new study by researchers at Aix-Marseille University has uncovered how Venus flytraps (Dionaea muscipula) initiate their rapid trap closures. They discovered the plant's cell walls lining the outer epidermis quickly soften, releasing stored energy.

🔬 Published on Thursday in Science, the findings suggest this rapid softening is the primary mechanism for the trap's initial closing motion, not water movement. This "fastest modulation of wall mechanics reported in plants" could inspire advancements in soft robotics.

🤔 The research team, led by Jeongeun Ryu, examined two previous hypotheses: water movement and cell wall relaxation. Their experiments showed water moved too slowly for the initial closure, supporting the cell wall softening theory.
