Stem cells from human skin keep to a 24-hour schedule that might protect them from sun damage. Salvador Aznar Benitah, then of the Centre for Genomic Regulation in Barcelona, Spain, and his colleagues analysed cultures of genetically identical stem cells from human skin at set times. They found that genes related to the 'body clock' are expressed in distinct waves over a 24-hour cycle.
