A team of physicists at the University of California at Santa Barbara has discovered some of the dynamics involved with active liquid surfaces at the microscopic level when energy is added. In their paper published in the journal Science, the group describes using high-speed cameras to capture the action as they activated mixed liquids by adding an energy source. Jérémie Palacci with the Institute of Science and Technology Austria has published a Perspective piece in the same journal issue outlining the importance of their work.
