LONDON, April 26 (Xinhua) -- You might never noticed it, but trees move even though there is no wind. Scientists have found that trees display minute and periodic pulses, as if they have subtle "heartbeats."

In the study, researchers from Denmark and Hungary investigated the overnight movement of 21 species of trees using terrestrial laser scanning, a high-precision three-dimensional surveying technique, the Guardian reported.

The researchers discovered the regular periodic changes in shape are synchronized across the whole plant and are shorter than a day-night cycle.

"We detected a previously unknown periodic movement of up to one centimeter in cycles of two to six hours," Andras Zlinszky at Aarhus University was quoted by the Guardian as saying.

3. so even trees are fidgety? I wish i had this to shove this in my grandmother's face!

4. Pretty cool!! I've also been curious whether trees feel "pain" when they are cut down.

I know plants respond to stimuli, like music, and grow differently than plants that don't receive such stimuli. Interesting stuff.

Scientists still can't detect a heart beat from the current US President !!
