Do vegetables scream when you cut them?
Researchers find an ultrasonic ‘scream’ is emitted when stems are cut or if species are not watered enough. A team of scientists at Tel Aviv University have discovered that some plants emit a high frequency distress sound when they undergo environmental stress.

Some people claim this one does, in a sense. Like the Ents from Tolkien’s Lord of the Rings saga (only a bit slower), a certain palm tree reportedly moves across the forest as the growth of new roots gradually relocates it.

Trees are “social creatures” that communicate with each other in cooperative ways that hold lessons for humans, too, ecologist Suzanne Simard says. Simard grew up in Canadian forests as a descendant of loggers before becoming a forestry ecologist.
