Circadian clocks are endogenous timekeeping mechanisms found in organisms from all kingdoms of life. These clocks coordinate vast programs of gene expression that allow organisms from bacteria to humans to organize their physiology and behaviour in optimal temporal relationships with the daily environmental cycles of light and dark. In the last two decades, scientists have made remarkable inroads into dissecting the molecular mechanisms that make up these clocks and how they drive rhythmic processes. In doing so, it has become evident that proper clock function is critical for optimal health and that many diseases are exacerbated by poorly functioning clocks. Despite the progress in understanding these timing systems, there is much more to learn. Therefore, we seek to bring together a collection of articles from scientists around the world that provide new insight into the roles of circadian clocks in immune function, metabolism, cancer, neuronal function and behaviour.
