Erratum
The Research News article by Roger Lewin "Genome planners fear avalanche of red tape" (30 June, p. 1543) incorrectly identified Maynard Olson as being involved in a gene mapping and sequencing project of the nematode Caenorhabditis elegans jointly with researchers at the Medical Research Council's Laboratory of Molecular Biology in Cambridge, England. In fact, Olson's Washington University, St. Louis, colleague Robert Waterston is organizing the U.S. end of the project.
