Publishing Editor: Claire Rawlinson AIMS AND SCOPE Each issue of Phil. Trans. R. Soc. B is devoted to a specific area of the biological sciences. (tel: +44 (0)20 7451 2602; fax: +44 (0)20 7976 1837; This area will define a research frontier that is advancing rapidly, often bridging [email protected]) traditional disciplines. Phil. Trans. R. Soc. B is essential reading for scientists working across the biological sciences. In particular, the journal is focused on the following four cluster areas: neuroscience and cognition; organismal and evolutionary biology; cell and developmental biology; and health and disease. As well as theme issues, The Royal Society is an independent scientific academy For further information on the Society’s activities, please the journal publishes papers from the Royal Society’s biological discussion meetings. founded in 1660 and self-governing under Royal contact the following departments on the extensions Production Editor: Matthew Whitaker For information on submitting a proposal for a theme issue, consult the journal‘s Charter.
