The contrasts between the sexes have inspired countless plays, novels, and other creative works. Sex differences inspire a group of developmental biologists, too-but there's a twist. While artists and most of the rest of us are fascinated by the effects of the male-female divide, these biologists are trying to learn how it arises in the first place. Their goal: to trace out the gene pathways that turn an embryo into a male or female. This quest has recently become one of the hottest areas of developmental biology, as two meetings held this year and devoted solely to the subject attest.

The millimeter-long roundworm Caenorhabditis elegans is amassing a sizable research following. As more and more people have joined teh confederation of research efforts loosely called the worm project (see Science, 15 June 1990, p. 1310), the community's biennial meeting has outgrown the traditional watering hole at Cold Spring Harbor. This year, the researchers moved inland for the Eighth International C. elegans Meeting, held June 1-5 on Lake Mendota at the University of Wisconsin, Madison. More than 500 "worm people" turned out to absorb progress reports on the sequencing of the C. elegans genome, the study of its developmental pathways-and some newer topics as well.
