Article Correctness Is Author's Responsibility: Pinpointing the cells that keep the body’s master circadian clock ticking

Scientists have developed a genetically engineered mouse and imaging system that lets them visualize fluctuations in the circadian clocks of cell types in mice. The method gives new insight into which brain cells are important in maintaining the body's master circadian clock. But they say the approach will also be broadly useful for answering questions about the daily rhythms of cells throughout the body.
