Almost ready for my beauty sleep.

Almost time for my beauty sleep.

Today I learnt that trees go to sleep.  Collaborative research by scientists from Austria, Finland & Hungary used infrared laser scanners to study whether there were any changes in trees from day to night.

“Our results show that the whole tree droops during night which can be seen as position change in leaves and branches ….. The changes are not too large, only up to 10 cm for trees with a height of about 5 meters, but they were systematic and well within the accuracy of our instruments.”

The researchers want to do more work to look at trees water use throughout the 24-hour cycle.
