Watching corals breathe: Researchers develop a new method to simultaneously measure flow and oxygen.

An international research team headed by the Max Planck Institute for Marine Microbiology in Bremen, Aarhus University and the Science for Life Lab in Uppsala has developed tiny particles that measure the oxygen concentration in their surroundings. In this way, they can track fluid flow and oxygen content at the same time – exciting prospects for many fields of research, from biology to physics.
