New research from University of California, Davis, shows why a species of tiny worm can learn to ignore an odor "“ information that could have implications for how human memories are formed.Scientists have known for decades that sensory neurons "“ nerves in places like our fingers, ears and eyes "“ begin the complex task of processing sights, sounds and other stimuli before forwarding the job to the body's mainframe computer: the brain. But just how these neurons accomplish...

Scientists discover a conserved signaling module controlling the formation of dauer or infective larvae in nematodes 150 years after Darwin's epochal "On the Origin of Species" many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and by the environment enabling the development of new species? Scientists at the Max Planck Institute for Developmental Biology in Tbingen, Germany, strive to decode the molecular basis of...

Scientists at the Instituto Gulbenkian de Ciencia (IGC) and the Faculty of Science of the University of Lisbon, in Portugal, have shown that populations of the worm Caenhorabditis elegans become resistance to pesticides in 20 generations, that is, in only 80 days.These findings, published last month in the journal PLoS ONE(*) open the way for future research into improved use of pesticides and antibiotics in pest and parasite control.Patrícia Lopes and co-workers followed 20...

An international team of biologists has discovered a new species of microsporidia, a single-celled parasite of animals, in a roundworm used in genetic laboratories around the world. The discovery, detailed in the current issue of the journal PLoS Biology, is a breakthrough for public health researchers who until now had been looking for a suitable laboratory model in which to study microsporidia"”a class of emerging pathogens that can cause significant illness in humans. "Microsporidia...

A previously unknown mutation discovered in a common roundworm holds the promise of new treatments for obesity in humans, McGill University researchers say. Their study was published Dec. 3 in the journal Nature, and was funded by the Canadian Cancer Society and the Canadian Institutes of Health Research.In lean times, a normal Caenorhabditis elegans worm goes into a form of suspended animation called "dauer" that slows its metabolism and allows it to survive for extended periods without...

The nervous system and the immune system have something in common. Each has evolved to react quickly to environmental cues. Because the nervous system is able to detect some of these cues--say, a characteristic odor signaling a pathogen's presence--at a distance, it sometimes can sense trouble earlier than the immune system, which has to wait until the pathogen invades the organism. So it makes sense that the two systems might talk to one another. Stanford University School of Medicine...

Two Americans and one Japanese researcher were awarded the 2008 Nobel Prize in Chemistry on Wednesday for the discovery and development of a brightly glowing protein first seen in jellyfish, which has helped scientists understand how cancer cells spread. American researchers Martin Chalfie of Columbia University in New York and Roger Tsien of the University of California, San Diego and Japanese-born Osamu Shimomura now of the Woods Hole Marine Biological Laboratory in Massachusetts received...

North Carolina State University scientists and colleagues have completed the genome sequence and genetic map of one of the world's most common and destructive plant parasites "“ Meloidogyne hapla, a microscopic, soil-dwelling worm known more commonly as the northern root-knot nematode. The research could help lead to a new generation of eco-friendly tools to manage the ubiquitous parasitic worm, which, along with other species of root-knot nematode, causes an estimated $50 billion in...

Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age. "We were really surprised," said Stuart Kim, PhD, professor of developmental biology and of genetics, who is the senior author of the research. Kim's lab...

RXi Pharmaceuticals Corporation (RXi) (Nasdaq: RXII), today announced that Victor Ambros, Ph.D., Professor of Molecular Medicine at the University of Massachusetts Medical School, has been appointed to the Company's Scientific Advisory Board, increasing the size of the Board to seven members. Dr. Ambros is known for his groundbreaking 1993 discovery of the first microRNA (miRNA). MicroRNAs are natural RNA interference compounds that are now known to regulate genes involved in a vast...

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...
