Behavioral ecologists have shown that many animals form social groups in conditions. Neurobiological evidence for this behaviour has now been discovered in the nematode worm, Caenorhabditis elegans. On pages 899 and 925 of this issue, de Bono et al. and Coates and de Bono present striking results on the genetic, molecular and neural mechanisms underlying nematode social feeding. These discoveries provide tantalizing insights into the effects of stress in social groupings.

Dissecting the sex life of the nematode worm Caenorhabditis elegans has already provided surprises for biologists interested in life-history theory. In a report on page 456 of this issue, Van Voorhies throws another spanner in the works by demonstrating that the costs of producing sperm are not as negligible as we might have thought.

Some species of the nematode worm (Caenorhabditis elegans) are sociable diners, clumping together to share a meal, yet others are more solitary. Why? According to a report by de Bono and Bargmann, these differences can be explained by a change of just one amino acid in a putative neuropeptide receptor.

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.
