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: 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 ...

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 ...

This is a preview. Log in through your library . Abstract Peristalsis enables transport of the food bolus in the gut. Here, I show by dynamic ex vivo intra-cellular calcium imaging on living embryonic ...

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 – ...
