Latest Caenorhabditis elegans Stories
WASHINGTON (Reuters) - How well you respond to stress predicts how long you will live, at least if you are a little worm, U.S. scientists reported on Monday.
University of Colorado at Boulder scientists have used a fluorescent marker to predict the individual life spans of identical worms that were genetically engineered to illuminate stress levels, implying living organisms have "hidden physiological states" that dictate their ability to deal with the rigors of life.
Tiny worms are taking the place of laboratory rats and mice for a Duke University scientist studying the effect of chemicals on the body. Researcher Jonathan Freedman has a $4 million contract from the National Toxicology Program to develop rapid toxicology tests on C. elegans roundworms.
Caenorhabditis elegans is a species of parasitic roundworm in the Nematoda phylum. It can be found in temperate regions, in many different areas of the world. It prefers to reside in nutrient rich soils. Its scientific name is derived from the Greek terms Caeno, meaning recent, rhabditis, meaning rod-like, and the Latin term elegans, which means elegant. It was first named by Maupas in 1900, but was not classified in the Caenorhabditis subgenus until 1952 by Osche. Caenorhabditis elegans...
