• Michael Rutter is a psychiatrist and professor of developmental psychopathology at the Social, Genetic & Developmental Psychiatry Centre, King’s College London – not a psychologist as we suggested (17 December 2005, p 32)
• We missed part of the credit for the Mars rover photo (24/31 December 2005, p 14). It should have read “Marco Di Lorenzo, Bernhard Braun, Doug Ellison and Ken Kramer courtesy of Aviation Week/JPL/NASA”.
