• In Jeremy Hyams's review of Life Itself (Nature 386, 778; 1997), the book's author, Boyce Rensberger, is incorrectly described as having attended the physiology course at Woods Hole Oceanographic Institute in Massachusetts, rather than the Marine Biological Laboratory. The laboratory has held a physiology summer course in Woods Hole for over a hundred years, and has been operating a science-writing fellowship programme since 1986, of which Rensberger now serves as co-director.
