Waste removal in worms reveals new mechanism to regulate calcium signaling

Calcium is so much more than the mineral that makes our bones and teeth strong: It's a ubiquitous signaling molecule that provides crucial information inside of and between cells. Scientists have discovered a new way that calcium signaling may be controlled. In worms, a specific microRNA fine tunes such signaling, a finding that should be of great help to the thousands of scientists who study the important role of calcium signaling in health and disease.
