When humans kick swim through water, vortices form around their legs, generating the force that propels them forward. However, the mechanisms underlying variations in the structure of these vortices ...

New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions.

Tsukuba, Japan—When humans kick swim through water, vortices form around their legs, generating the force that propels them forward. However, the mechanisms underlying variations in the structure of ...

Artist's impression of a tiny swimming creature: The body is modelled as a chain with several mass points in the computer simulation. Bacteria can do it, amoebas can do it, even blood cells can do it: ...

In all basic artistic swimming positions, the arm positions are optional for the swimming. Additionally, toes must be pointed and the legs, body and neck all must be fully extended unless otherwise ...
