In the 1970s biologist Sydney Brenner and his colleagues began preserving tiny hermaphroditic roundworms known as Caenorhabditis elegans in agar and osmium fixative, slicing up their bodies like ...

Caenorhabditis elegans, one millimeter long, has just 959 cells. The worm’s simplicity has made it a mainstay of scientific research. Skip to content Skip to site index.

Pattern recognition system that monitors disease-causing bacteria in C. elegans A nuclear hormone receptor intercepts pathogen-derived signals of growth and virulence, revealing an evolutionarily ...

C. elegans can be grown in a petri-dish containing E. coli in the laboratory, as their natural diet is bacteria. Because of their small size, large numbers of C. elegans can be maintained in the ...

Researchers demonstrated that the microscopic worm C. elegans uses a retrotransposon called Cer1 to transfer a learned behavior (avoidance of a pathogenic bacterium) between worms. In earlier work ...

C. elegans nematodes, or roundworms, undergo examination by project scientists. The worms are descendants of those that were part of an experiment that flew on the shuttle Columbia's last mission ...

Researchers have identified an endogenous insulin antagonist, INS-7, in Caenorhabditis elegans that modulates fat loss by inhibiting a gut-to-brain signaling pathway involving the neuropeptide FLP-7.
