Tadpoles are known to possess incredible regenerative capacities: if they lose their tail, a new one will grow back within a week. Understanding the mechanisms underlying the regeneration process would have considerable implications for research in human healing. Encouraged by his earlier research that identified a role for reactive oxygen species (ROSs) in tadpole tail regeneration, Enrique Amaya and his team at the University of Manchester (UK) decided to follow up on this result in a study published in Nature Cell Biology (published online 13 January 2013; doi:10.1038cb2659).
