The workings of electricity are often introduced to students by way of a comparison to water, with voltage analogous to pressure, current to flow rate, wires to hoses, and so on. Even in more advanced ...

We describe electricity as a flow, but that’s not what happens in a typical wire. Physicists have begun to induce electrons to act like fluids, an effort that could illuminate new ways of thinking ...

A new microscale gas chromatography system integrates all fluidic components into a single chip for the first time. The design leverages three Knudsen pumps that move gas molecules using heat ...

Ever feel run off your feet? Spare a thought for sea stars, creatures whose movement involves the coordination of hundreds of ...
