Even after 20 million years of evolutionary separation, two tiny worm species show astonishingly similar patterns in how they turn genes on and off. Scientists mapped every cell s activity during ...

A representation of single-cell RNA sequencing data from two species of worms, C. elegans (left) and C. briggsae (right). Each point represents a single cell, arranged such that cells from the same ...

Scientists reveal the homolog of a well-known human protein, Nucleolin, in the tiny, transparent roundworm, C. elegans. Nucleolin is linked to human neurodegenerative disease and cancer. The new ...

HOUSTON - (Dec. 22, 2020) - Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her ...

Two species of worms have retained remarkably similar patterns in the way they switch their genes on and off despite having split from a common ancestor 20 million years ago, a new study finds.
