In otherwise hard times, at least one market for science writing appears to be expanding: writing for scientists, particularly online. It's also a market that can offer unusual professional satisfaction. When you write for scientists, you can ignore many of science and medical journalism's topical fads. On the Web, you can pursue subjects that interest you, delve into more of their technical details, and write about them with surprising flexibility and freedom. Like everything else in the dot-corn world, online-only publications for scientists have come and gone. I, for one, am still mourning the disappearance of BioMedNet, which Elsevier dropped at the end of 2003. For several years BMN was an important market. It published at least a couple of news stories every weekday and also covered several basic research conferences annually. But there's good news, too: A few online news operations allied with print publications are still going strong. These outlets, such as TheScientist.com (www.the-scientist.com) and NewScientist.com (www.newscientist.com), publish unique content that does not appear in their print versions. Top weekly journals also publish daily news online—among them Nature (www.nature.com/news) and Science (sciencenow.sciencemag.org). So does the top-tier publication Scientific American (www.sciam.com), which appeals both to those with an armchair interest in science and to scientists themselves. The stories in these online publications—typically short, in the range of 400 to 600 words—are written by both staffers and freelances. One of the best things about writing for scientists on the Web is that it's not like typical Web writing at all. It resembles traditional print writing—but, amazingly, often with fewer constraints. And it is garnished only lightly with electronic doodads. Publications for scientists are not mad for multimedia, so your words don't have to take second (or third) place to video documentaries, interactive quizzes, Flash animation, or chat. Hyperlinks, yes, but only rarely will there be slideshows or snazzy static graphics. Nor is this a deeply collaborative process. Usually it's just you and your editor, who often leaves you to produce your piece in your own way. This is different from Web writing in general, when you might be part of a Web content team whose other members regard you as the least valuable player.
