  • Engineers create tiny nanomotor small enough to fit inside human cells

    Mechanical engineers at the University of Texas have created the world’s smallest, longest running nanomotor. The tiny mechanical marvel is so small that it can fit inside a human cell. To put that in perspective, the motor is 500 times smaller than a grain of salt. Beyond miniscule. Nanomotors are microscopic machines that do exactly what a motor does: rotate. Although this might seem like something out of a sci-fi film, at a microscopic level, a lot of cells already deploy this principal. Using motorized flagella or cilia to navigate their way around other cells, ward off pathogens, or even...
