'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.

Catching fast changes in excited molecules

It's hard to see certain molecules react. The reaction is just that fast. Until now. A team of scientists devised a way to reveal time- and energy-resolved information on "dark" states of molecules—ones that are normally ...
