Pollen starts to dry out when it leaves the flower, which can destroy the genetic material the grain is carrying. To combat dehydration, pollen grains have evolved a way of folding up to prevent water from leaking out. Eleni Katifori and colleagues describe the physics of pollen folding in a new paper in the Proceedings of the National Academy of Sciences. Music courtesy of Prelinger Archives.
