These tiny water-gathering grooves allow a type of moss called Syntrichia caninervis to survive in desert climates where it rarely rains. The plant, which collects water with its leaves instead of roots, can also rehydrate from a dry state when it has access to moisture. A team from Brigham Young University, Utah State University and the China’s Xinjiang Institute of Ecology and Geography, documented the role of tiny hair-like structures on the plant’s leaves and how airborne droplets are attracted to nano-structures on top of each hair. Information about how desert plants survive with no rainfall might help humans determine better ways to collect water in dry environments.
