Humidity‐driven shape morphing enhances fog harvesting in porous cactus spines

New Phytologist, EarlyView.
Spine straightening and water collection during fog exposure in Turbinicarpus alonsoi. Summary Cacti develop spines instead of conventional leaves, which often serve as mechanical defence against herbivores. However, some cactus species grow porous and flexible spines, suggesting fundamentally different functions.
