High-precision three-dimensional surveying of 21 different species of trees has revealed a yet unknown cycle of subtle canopy movement during the night. The 'sleep cycles' differed from one species to another. Detection of anomalies in overnight movement could become a future diagnostic tool to reveal stress or disease in crops.
One of the most important processes sustaining life on Earth is the transport of water from the ground and into the leaves where the photosynthesis and capture of the sun's energy take place. The process has fascinated scientists for centuries and is still debated in plant physiology. Scientists generally agree that water transport is driven by light and consequently occurs in 24 hours cycles.
