DNA damage modulates sleep drive in basal cnidarians with divergent chronotypes - Nature Communications Here, the authors use the diurnal upside-down jellyfish and the crepuscular starlet sea anemone as simple nerve net models to examine the potential evolutionary origins of sleep. They describe and define sleep patterns in these species, finding that sleep deprivation increases neuronal DNA damage and that sleep facilitates genome stability. https://go.nature.com/4qtyoUd
