Scientists have long seen evidence of social behavior among many species of animals, both on the earth and in the sea. Dolphins frolic together, lions live in packs, and hornets construct nests that can house a large number of the insects. And, right under our feet, it appears that nematodes–also known as roundworms–are having their own little gatherings in the soil. Until recently, it was unknown how the worms communicate to one another when it's time to come together. Now,...

The BioSciences Website EurekaMag.com publishes articles in all areas of biological science. The latest articles cover Fireflies which are winged beetles chemically producing light from their lower abdomen, Synapse which is a structure in the nervous system that permits neurons to pass an electrical or chemical signal to another cell. The article on Lotus covers the aquatic perennial plant commonly cultivated in Southeast Asia for its edible seeds and rhizomes. Mannheim, Germany (PRWEB)...

Researchers say discovery may reveal new uses of existing medications to reverse anesthesia Physicians use inhalation anesthetics in a way that is incredibly safe for patients, but very little is known about the intricacies of how these drugs actually work in children and adults. Now, researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to a new study from the Seattle Children's Research Institute. C. elegans is a transparent...

A new study, conducted by researchers at the University of California, San Francisco, has shed new light on a genetic disease known as Bardet-Biedl syndrome (BBS)–a condition in which patients show mental and developmental delays, short stature, early onset blindness, extra digits on the hands and feet, kidney abnormalities and obesity. While the occurrence of BBS is rare–occurring in roughly 1 in every 150,000 live births–scientists believe that by understanding the...

Reseach presented at ASCB annual meeting Reproductive and somatic aging use different molecular mechanisms that show little overlap between the types of genes required to keep oocytes healthy and the genes that generally extend life span, according to Coleen Murphy, Ph.D., of Princeton University, who described her new findings on oocyte aging at the American Society for Cell Biology Annual Meeting Dec. 6 in Denver. The different genetic pathways help explain why a woman's fertility...

Tiny Worms Could Hold Key To Living In Space

Microscopic worms similar in biological makeup to human beings have returned from a successful space mission, proving for the first time that worms can survive in space. Caenorhabditis elegans (C. elegans), a worm family that originated in a rubbish dump in Bristol, England, were sent into space to give researchers a better understanding of how humans can survive in space -- if ever comes the time when we have to flee our planet and start anew elsewhere in the heavens. University of...

The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly. That's the conclusion of biologists at the University of California, San Diego who have discovered genes in the laboratory roundworm C. elegans that signal the presence of surface wounds and trigger another series of...

In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients. The scientists, working in and in collaboration with the lab of Whitehead Member Susan Lindquist, established these previously unknown links in an unexpected way. They used a very simple cell type–yeast...

A study in worms that are less than a millimetre long has yielded clues that may be important for understanding how nerves grow. A team of researchers from the Queensland Brain Institute (QBI) has probed the molecular mechanisms which prompt the development of dendrites, in the nematode Caenorhabditis elegans. The findings are published September 20 in the online, open access journal PLoS Biology. Dendrites are the branch-like structures in nerve cells, which receive electrochemical...

Sanford-Burnham researchers unravel how the interplay between two cellular processes–autophagy and lipid metabolism–influences lifespan in C. elegans worms Aging is generally accepted as a universal fact of life, but how do humans and other organisms age at the molecular level? At Sanford-Burnham Medical Research Institute (Sanford-Burnham), a team led by Malene Hansen, Ph.D., uses a type of worm called Caenorhabditis elegans to work out the molecular underpinnings of the aging...

Caenorhabditis elegans
2014-01-12 00:00:00

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...
