Abstract
Nature 381, 796-800 (1996). THE Nature cover relating to this letter, in the 27 June issue, did not do justice to the original image. The image has now been re-scanned to emphasise the significant features (right), and the new and improved version will be available on reprints of the letter. In addition, credit should have been given in the caption to Dr Luis Ruiz-Avila.
