Fast-freeze snapshot yields new picture of nerve-muscle junction

... technique was used with tiny, one-millimeter-long nematode worms, a lab animal widely studied by neuroscientists. Investigators report the finding in the Aug. 2 issue of the Journal of Neuroscience. Janet Richmond, associate professor of biological sciences at the University of Illinois at Chicago, is the c...

NYU biologists identify gene that coordinates two cellular processes

...eam is using functional genomic tools to study the nematode worm Caenorhabditis elegans (C. elegans), the first animal species whose genome was completely sequenced and a model organism to study how embryos develop. The study appearing in Current Biology was performed by NYU's Fabio Piano, an assistant profe...

New clues to how sex evolves

...of this complex question in ongoing studies of the nematode Caenorhabditis elegans. Abby Dernburg, of Berkeley Lab's Life Sciences Division and UC Berkeley's Department of Molecular and Cell Biology, working with graduate student Carolyn Phillips, has identified a key family of genes and proteins that help ...

Biologists call for better choice of model organisms in 'evo-devo'

...n inherited from developmental biology (fruit fly, nematode worm, frog, zebrafish, chick and mouse). To help understand how developmental change underpins evolution, evo-devo researchers have, over recent years, selected dozens of new model organisms, ranging from sea anemones to dung beetles, to study. ...

Minuscule molecules pack a powerful punch

...ve an effect in mice: previous knockout studies in nematode worms suggested that most microRNAs were not essential. Our findings were dramatically different." The effects of the miR-155 knockout swept across the immune system. The team showed that, although knockout of miR-155 did not appear to affect norm...

How stem cells are regulated

...nesis. The conclusions are based on studies of the nematode (roundworm) C. elegans and studies of mouse embryonic stem cells. The C. elegans studies were carried out in collaboration with another of BRIC’s research groups, led by Associate Professor Lisa Salcini. The BRIC researchers are currently develop...

Meat and two neutrons -- the key to a longer life

...ail Shchepinov, formerly of Oxford University, fed nematode worms nutrients reinforced with natural isotopes (naturally occurring atomic variations of elements). In initial experiments, worms' life spans were extended by 10%, which, with humans expected to routinely coast close to the centenary, could add a f...

Study of planarians offers insight into germ cell development

...ific study ?model creatures such as the fruit fly, nematode or mouse. But University of Illinois cell and developmental biology professor Phillip Newmark thinks it should be. As it turns out, the tiny, seemingly cross-eyed flatworm is an ideal subject for the study of germ cells, precursors of eggs and sperm ...

Secret of worm's poison pill box protein could produce new natural insecticide

...ge of natural insecticides. It had been known that nematode worms can infect and kill insect pests with the h... uses a protein (XptA1) a toxin which helps the nematode to kill and feed on the dead body of the insect. The toxin not only kills the target insect but prev...

Uniform language for describing genes of pathogenic and beneficial microbes

...he same terms can be used for species ranging from nematode worms to bacteria. Having these terms in place will greatly enhance research in this area.? In the current update, the PAMGO consortium, in collaboration with Jane Lomax and Amelia Ireland of the GO Consortium’s editorial office at the European Bio...
