Trees Use 'Muscle-Like' Tension Wood to Correct Their Posture, Study Finds

Beneath the stillness we attribute to trees, a quiet intelligence has long been at work. French researchers at INRAE and the University of Clermont Auvergne have revealed that trees possess proprioception — an awareness of their own shape — and deploy a specialized wood on alternating sides of their stems, functioning like opposing muscle groups, to pull themselves back into upright alignment.
