Fresh off the press! Jeongeun and Yoël’s work on the lightning-fast actuation of the Venus flytrap. 🪴⚡ No muscles. No nerves. So what powers the trap? Cutting the trap suppresses its mechanical amplifier, the snap-through instability, and reveals the active motion.

New research in Science reveals that the Venus flytrap's snap is triggered by a rapid softening of the epidermal cell walls, uncovering the physical mechanism behind this remarkable movement. Learn more in this week's issue:

Preprint 🌱 Plants build nonlinear vectorial representations of light patterns! Surprising results: Opposing cues cancel, so plants grow towards a weaker tie-breaker light. Plants respond to sum of transduced signals, not physical sum of light: optical “illusions”! 🪩
