Caption: Purdue University researchers use an optical electrode, or optrode, right, to measure oxygen consumption in a two-day-old fathead minnow embryo, about half the width of the head of a pin. By watching for worrisome changes within these tiny fish eggs, the technology could be used as a monitoring tool against environmental contamination or even biological weapons.
