Stick insect's propulsion joint discovered

The stick insect is a popular model organism in biological research for gaining a better understanding of insect walking movements. The advantage of the stick insect is that the structure of its body parts and nervous system are comparatively simple. For decades, textbooks have claimed that the force for maintaining body posture and driving movement was controlled independently by different joints. Now, as biologist Chris Dallmann reports, "this is not correct." The doctoral researcher at the Cl
