Asymmetric fluid flow in helical pipes inspired by shark intestines. Proceedings of the National Academy of Sciences, 2024; 121 (40) DOI: 10.1073/pnas.2406481121 ...

This opens up the possibility of liquid transport along dynamically changing paths in industrial and laboratory settings. Alternatively, flow could be redirected by changing the spacing between fins.
