New Scientist, 29 August, 1998 FEEDBACK As a peer review journal, Nature is usually the first to report the research that appears in its pages. Just occasionally, however, the magazine gets scooped. Thus a "news" item in the journal at the beginning of August reported that it rains more often on weekends than on weekdays. But this wasn't news to Feedback, who enjoys dipping into the humour magazine The Annals of Improbable Research. In the March/April issue of that journal, David Schultz of the National Severe Storms Research Laboratory in Norman, Oklahoma, reported the same phenomenon. Will Nature reprimand its referees for failing to notice prior publication?
