     In the September 2014 issue, the piece “Blood feud: The debate over how long blood lasts” (Nat. Med. 20, 979–982, 2014) stated that proteins in stored blood “can scavenge nitrous oxide” and that “nitrous oxide might tighten blood vessels.” However, the story should have referred to nitric oxide, not nitrous oxide. The error has been corrected in the HTML and PDF versions of this article.
