A new study published in the journal Nature Physics has revealed an odd form of elasticity in human sperm cells. This new elasticity allows them to move through fluids while maintaining a “skirt”-like structure, similar to a skirt in a dress. This has allowed scientists to gain a greater understanding of how human sperm cells move and may lead to new treatments for male infertility.

The study found that when sperm cells come into contact with surfaces, they form a skirt-like structure that helps them move through fluids. This skirt helps to reduce the amount of friction between the sperm cell and the surface, allowing them to move faster and more efficiently. This is a new type of elasticity, which means that the sperm cells are able to change their shape in response to their environment. This is in contrast to Newtonian fluids, which are fluids that do not change their shape in response to pressure.
