Going upstream, and against a current, involves a front-first downward tilt and then moving along a surface, shows new research by a team of scientists, which created “nano-motors” to uncover this effective means of locomotion under such conditions. Its findings and the creation of these tiny motors offer new insights into the nature of movement in fluids and have implications for engineering.
