Earthworms move through the soil not just by wriggling around, but by sending peristaltic waves down their bodies. A new robot, which employs that same strategy, could one day be used in underground ...

Figure 1: Genetic elimination of sensory function or structure in the Drosophila embryonic peripheral nervous system. Figure 5: Bursts of forward peristalsis but not sporadic forward waves are ...

A research paper by scientists at Tianjin University presented an earthworm-inspired multimodal pneumatic continuous soft robot enhanced by wire-winding transmission. The research paper, published on ...

a: The response to swallowing is marked by the mylohyoid muscle electromyogram. With primary peristalsis, note that the delay in onset of depolarization, spike burst, and esophageal contraction in the ...

To keep blood and oxygen flowing throughout their bodies, most animals depend on a beating heart. But researchers reporting in Current Biology on July 10 have discovered that sea spiders use a strange ...

(CN) – Researchers have discovered sea spiders rely on waves of gut contractions to circulate fluids and breathe, rather than with a beating heart as most animals do. These spindly arthropods – ...
