'Chaotic' way to create insectlike gaits for robots

Researchers in Japan and Italy are embracing chaos and nonlinear physics to create insectlike gaits for tiny robots—complete with a locomotion controller to provide a brain-machine interface.

Magnetic bacteria as micropumps

ETH scientists use magnetic bacteria to control liquids at the micro level. They are already thinking about using them in the human bloodstream for precision delivery of cancer drugs to a tumor.

Cancer cells 'remove blindfold' to spread

Cancer cells spread by switching on and off abilities to sense their surroundings, move, hide and grow new tumors, a new study has found.
