One day, he found himself in a chance lunchtime conversation about dimethyl sulfide (DMS). The DMS story started in 1972 with the publication of an influential paper by James Lovelock

Nature has long been linking to Wikipedia ? ?the free encyclopedia that anyone can edit? ? from its online news stories. On Aug. 25, 2005, Nature cited the Web site in a print editorial. So there was perhaps a collective sigh of relief in the journal?s offices when an in-house investigation, published on December 15, found that the site?s scientific content is not much less trustworthy than that found in tried-and-tested print encyclopedias. Since its launch in 2001, Wik
