'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 ...

Scientists create anti-laser for a condensate of ultracold atoms

An international team of scientists developed the world's first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists have demonstrated that it is possible to absorb the selected ...

Study unravels long-held Fermi puzzle tied to nonlinear systems

In physics, the Fermi-Pasta-Ulam-Tsingou (FPUT) problem—which found that certain nonlinear systems do not disperse their energy, but rather return to their initial excited states—has been a challenge that scientists have ...

Predicting the extent of flash flooding

Devastating floodwaters such as those experienced during Iowa's Flood of 2008—which swamped many Iowa communities, along with ten square miles of Cedar Rapids—are notoriously difficult to predict.
