A News item in the 3 June issue of Nature (429, 490; 2004)10.1038/429490b erroneously states that Hanyang University Hospital's Institutional Review Board (IRB) was in violation of Korean Food and Drug Administration guidelines. The article says that the guidelines require IRBs to include more than one layperson. In fact they only require one, which this IRB had appointed. The error in the text was made by a Seoul-based translation company that Nature paid to translate the document. Nature asked the translator to verify the passage prior to publication, but the mistake was overlooked. We apologize for the error.
