Responses to environmental stimuli are mediated by the activation and inactivation of various signalling proteins. However, the temporal dynamics of these events in living animals are not well understood. Here we show real-time imaging of the activity of the key regulator of the MAP kinase pathway, Ras, in living Caenorhabditis elegans and that Ras is(More)
