Snake scales protect steel against friction

A snake moves without legs by the scales on its belly gripping the ground. It generates friction at the points needed to move forwards only and prevents its scales from being worn off by too much friction. Researchers of ...

Researchers study ways to make stronger materials in 3-D

(Phys.org) —Aided by funding from NASA and using methods similar to 3-D printing, researchers at Missouri University of Science and Technology are running computer simulations of processes that could lead to stronger, more ...
