Mysteries of grasshopper response to gravity unlocked

How do insects control the effects of gravity when they climb a tree or hang upside-down waiting for prey? They don't have closed circulatory systems that restrict fluid flow to certain parts of the body. Researchers discovered how insects adjust their cardiovascular and respiratory activity in response to gravity. When they change orientation, they respond to gravity just like humans, and they show many of the same physiological responses.
