A controversial idea from the mid-20th century is attracting renewed attention from researchers developing theories for how cognition arises with or without a brain.

The roundworm uses cues from visible light to help avoid eating toxic bacteria with a distinguishing hue.

The Yale neuroscientist seeks to understand the brain’s architecture and function using C. elegans.

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.

One of the foremost molecular biologists of the 20th century, the Nobel laureate established C. elegans as a model organism, mapping its genes and development.

The protein RhoA coordinates pulses of movement in Caenorhabditis elegans cells.

A transgenic approach allows researchers to collect the organelles from specific cells in nematodes with unprecedented efficiency.

Adding a fusion gene to certain mitochondria in C. elegans enables researchers to collect and analyze them.

Unsuccessful attempts to reproduce the results of a 2015 study reporting that C. elegans orient themselves by Earth’s magnetic field spark debate among researchers.

The biologist earned a Nobel Prize in 2002 for his work on C. elegans.

Maintaining dynamic connections among the body’s mitochondria is required for the health and life-extending benefits of low-calorie diets for nematodes.
