Science writer Olivia Judson has a post about tools for organizing the source materials for an article. I'd like to know what she writes the actual article with.

Here's her biographical blurb from the NY Times: Olivia Judson, an evolutionary biologist, is the author of "Dr. Tatiana's Sex Advice to All Creation: The Definitive Guide to the Evolutionary Biology of Sex," which was made into a three-part television program. Ms. Judson has been a reporter for The Economist and has written for a number of other publications, including Nature, The Financial Times, The Atlantic and Natural History. She is a research fellow in biology at Imperial College London.
