A phthalate commonly found in shampoos, cosmetics, and cleaning products disrupts reproduction in worms.

Working with bacteriophages and nematodes, the University of California, Berkeley, molecular biologist uncovered a role for genetic switches in early development.

A small RNA in Pseudomonas triggers an avoidance response in C. elegans that can be passed on to the next generation, according to research presented at this week’s meeting of the American Society for Cell Biology.

A single-cell map of C. elegans’s transcriptome during development finds cell lineages that start out genetically different and end up as cells of similar function and genetic profile.

This newly described behavior occurs spontaneously, but can be modulated by food availability, temperature, and the size of the chambers.

A major sensory neuron in roundworms distinguishes proprioception from harmful touch by sending out local or whole-cell signals, respectively.

Worms with the reproduction-related TCER-1 gene deleted could fight off infection for longer and survived better when exposed to heat and radiation.

The connectomes trace 385 neurons in the male worm and 302 neurons in the hermaphrodite worm.

Two research groups demonstrate that in Caenorhabditis elegans, behavioral traits can be passed down through the germline to future generations, even though they aren’t hard-wired.
