Investigation of meiosis in the nematode Pristionchus pacificus has illuminated evolutionary variation in this essential aspect of reproduction and established a new model for future study.

A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny.

Unexpected structural diversity of nematode small molecules, as revealed by high-resolution phylogenetic analysis, suggests recurrent biochemical innovation, a pattern that is probably typical across animals.

The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.

The protein components of an essential and conserved meiotic interface, the synaptonemal complex, have highly conserved coil-coiled domains and protein length, despite highly diverged sequence.

hamPCR is a cost-effective and transformative amplicon sequencing strategy to describe microbiota composition and measure its overall abundance, applicable to all samples in which host and microbial DNA are co-extracted.

Caenorhabditis elegans responds to predator threat by using dopamine signaling to alter the distribution of their eggs.
