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.

A heat map of gene expression provides insights on the genes that help C. elegans survive severe caloric restriction.  

When it comes to thwarting roundworms, scientists find that combining four antiparasitic drugs in smaller doses packs a greater punch than the four drugs alone.

E. coli that make indoles protect older worms, flies, and mice from frailty. 

Food restriction decreases a metabolite that impedes associative learning in worms.
