Study shows that selection pressures imposed by predator fungi have shaped escape behavior in microscopic worms Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection. Animals explore their environment to find food, find mates and locate new habitats, and have developed distinct escape responses to avoid predators,...

The development of identical egg laying organs of two nematode species is regulated by different signaling pathways Changes in a short protein domain can alter a whole signaling network involved in organ development"“ this is the key result of a comparative study of the development of the egg laying organ in two species of nematodes. However, the outward appearance of the organ remains the same in both species. The study provides support for the theory of developmental systems drift...

A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly. The worms "” from The University of Nottingham "” were flown into space onboard the Space Shuttle Atlantis. They spent 11 days in orbit onboard the International Space Station more than 200 miles above the earth. Many...

(Ivanhoe Newswire) -- Scientists have discovered a new role for a biological pathway that not only signals the body's metabolic response to nutritional changes but also affects lifespan. The researchers conducted the study on Caenorhabditis elegans (nematodes). Dietary restriction is a way to extend lifespan and postpone age-related diseases in many species including yeast, worms, flies and rodents. However, researchers have been unclear about the molecular signals involved until this study....

New discovery advances study of diet and longevity A team led by a scientist from the Florida campus of The Scripps Research Institute has identified a new role for a biological pathway that not only signals the body's metabolic response to nutritional changes, but also affects lifespan. The study, published in the May 12, 2011 issue of the journal Nature, was conducted on Caenorhabditis elegans (nematodes or roundworms), which are a widely accepted model for human aging research. "Not only...

New technique reveals functional gene networks in a live organism An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have developed a new method for discerning the functions of previously uncharacterized genes and placing them in interactive, functional networks that reveal how gene products interact to bring about cellular events. The research was published in the April 29 issue of the journal Cell. It was led by principal...

By Danielle J. Whittaker, BEACON Center for the Study of Evolution in Action, Michigan State University Researchers are decoding the patterns that connect different types of nerve cells Though the brain may seem impossibly complex, it can be understood as a network, much like computer chips or the Internet. A new analysis in the journal PLoS ONE has described the workings of a worm's nervous system as patterns involving the connections among nerve cells with different functions. Unlike the...

For worms, choosing when to search for a new dinner spot depends on many factors, both internal and external: how hungry they are, for example, how much oxygen is in the air, and how many other worms are around. A new study demonstrates this all-important decision is also influenced by the worm's genetic make-up. In the simple Caenorhabditis elegans nematode, the researchers found that natural variations in several genes influence how quickly a worm will leave a lawn of bacteria on which it's...

New research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) has shown that nematode worms have to trade-off resistance to different diseases, gaining resistance to one microbe at the expense of becoming more vulnerable to another. This finding, published in PLoS ONE today (2 March 2011), reveals that the worms, called C. elegans, have a much more complex immune system than was previously thought and shows how important such trade-offs are across the animal...

By Caroline Arbanas, Washington University in St. Louis Scientists have decoded the DNA of the parasitic worm that causes trichinosis, a disease linked to eating raw or undercooked pork or carnivorous wild game animals, such as bear and walrus. After analyzing the genome, investigators at Washington University School of Medicine in St. Louis and their collaborators report they have identified unique features of the parasite, Trichinella spiralis, which provide potential targets for new drugs...

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...
