NC State Researchers Get to Root of Nematode Genome
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.   view more (2008-09-24)

Worm genome offers clues to evolution of parasitism
The genome of a humble worm that dines on the microbial organisms covering the carcasses of dead beetles may provide clues to the evolution of parasitic worms, including those that infect humans, say scientists at Washington University School of Medicine in St. Louis and the Max-Planck Institute... view more (2008-09-24)

ISU researchers help map first plant-parasitic nematode genome sequence
There are numerous plant-parasitic nematodes in the world, but only a handful are responsible for the largest part of an estimated $157 billion in agricultural damage globally every year. Nematodes are small worms that burrow into plant roots and feed off living cells.    view more (2008-09-05)

Mate or hibernate? That's the question worm pheromones answer
If worms could talk, they might tell potential suitors, "I like the way you wriggle," complete with that telltale come slither look.   view more (2008-07-25)

Sex and lifespan linked in worms: a family of sugar-like molecules controls both
A group of scientists who set out to study sex pheromones in a tiny worm found that the same family of pheromones also controls a stage in the worms' life cycle, the long-lived dauer larva.   view more (2008-07-24)

New research on mutation in yeast can enhance understanding of human diseases
Yeast, a model organism heavily relied upon for studying basic biological processes as they relate to human health, mutates in a distinctly different pattern than other model organisms, a finding that brings researchers closer to understanding the role of evolutionary genetics in human diseases and... view more (2008-06-20)

Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn.   view more (2008-04-14)

Soybean varieties viable in southern Indiana, resistant to root-knot nematode
Purdue University researchers have identified several soybean varieties that grow well in areas of the Midwest like southern Indiana and are resistant to root-knot nematodes, a plant-destroying parasite with a recently confirmed presence in that part of the state.   view more (2008-03-24)

Deep-sea species' loss could lead to oceans' collapse, study suggests
The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press.   view more (2007-12-28)

Overexcited neurons not good for cell health
Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.   view more (2007-12-18)

New research to decode the genetic secrets of prolific potato pest
The full weight of a consortium of world-leading scientists - including those who helped decode the entire human genome - is being thrown at a parasitic worm less than 1mm long.   view more (2007-11-28)

Drug commonly used to treat bipolar disorder dramatically increases lifespan in worms
Nematode worms treated with lithium show a 46 percent increase in lifespan, raising the tantalizing question of whether humans taking the mood affecting drug are also taking an anti-aging medication.   view more (2007-10-31)

Unravelling new complexity in the genome
A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans.   view more (2007-08-14)

Outwitting pesky parasites
Across the southern United States, an invisible, yet deadly parasite known as the root-knot nematode is crippling soybean crops.   view more (2007-07-16)

Executable biology -- Computer science sheds light on animal development
By applying the techniques of computer engineering to a mechanistic diagram describing the development of the Nematode C. elegans, a group of researchers in Switzerland has been able to tease out what laboratory experiments have not - how and when the crucial cross-talk between cellular signaling... view more (2007-05-18)

Researchers at Illinois explore queen bee longevity
The queen honey bee is genetically identical to the workers in her hive, but she lives 10 times longer and - unlike her sterile sisters - remains reproductively viable throughout life.   view more (2007-05-09)

Minuscule molecules pack a powerful punch
A role for a microRNA in the immune system has been shown by study of one of the world's first microRNA knockout mouse, reported Friday 27 April in Science.   view more (2007-04-27)

Study of planarians offers insight into germ cell development
The planarian is not as well known as other, more widely used subjects of scientific study - model creatures such as the fruit fly, nematode or mouse.   view more (2007-04-25)

Secret of Worm's Poison Pill Box Protein Could Produce New Natural Insecticide
Researchers at the University of Warwick have discovered how a protein from a bacterium acts like a cunningly designed poison pill box that could now be used as a basis of a new range of natural insecticides.   view more (2007-03-13)

Scientists expand microbe 'gene language'
An international group of scientists has expanded the universal language for the genes of both disease-causing and beneficial microbes and their hosts.   view more (2007-03-02)

Uniform language for describing genes of pathogenic and beneficial microbes
An international group of scientists has announced a major expansion of a lingua franca used to describe the activities of genes in living organisms.   view more (2007-03-01)

How stem cells are regulated
Researchers from Biotech Research & Innovation Centre (BRIC) at University of Copenhagen have identified a new group of proteins that regulate the function of stem cells. The results are published in the new issue of Cell.   view more (2007-02-23)

Mutant gene shatters nerves
If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.   view more (2007-01-30)

Tiny worm provides model for the genetics of nicotine dependence
The unassuming C. elegans nematode worm, a 1-millimeter workhorse of the genetics lab, is quite similar to human beings in its genetic susceptibility to nicotine dependence.   view more (2006-11-03)

UGA scientists engineer root-knot nematode resistance
University of Georgia professor Richard Hussey has spent 20 years studying a worm-shaped parasite too small to see without a microscope.   view more (2006-09-27)
