The flow of matter, from macroscopic water currents to the microscopic flow of electric charge, underpins much of the infrastructure of modern times. In the search for breakthroughs in energy ...

Using a laser to stimulate a photocurrent and a magnetic field to control it, researchers have devised a scheme for measuring a current’s flow stream. Why there’s a need to assess current-flow ...

Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere. “These currents ...
