Aaron J. Sender, (“Happy Days at the HAP Factory,” p. 26), was torn between the worlds of science and writing before realizing he could be citizen of both. After graduate training in both biology and journalism at New York University and experience at The Sciences and Discover, he reported for GenomeWeb.com and BioInform before joining the staff of Genome Technology as senior writer. Lately, he’s been trying to save up some cash for a high-throughput sequencer to use at parties.
