worm C. elegans as a model organism. His research group looks at genetic mutations to see what effect they cause. From that information they can determine which genes are involved in certain biological processes. The mutation they found in this disco...
Parasite whips up ideas for bowel cancer treatments
...hipworm (trichuris trichiura) is a 3cm-to-5cm-long nematode
or roundworm that gets its name from its whip-like shape. Once inside their host, adult worms produce eggs that are passed in the faeces and mature in the soil. If the eggs are ingested, they hatch in the large intestine where they can cause trichuri...

Evolutionary conservation of a mechanism of longevity from worms to mammals
Though the study of aging in the nematode
model organism C. elegans has provided much insight into this complex process, it is not yet clear whether genes involved in aging in the worm have a similar role in mammals. In a recent study, Dr. Hekimi and colleagues of McGill University (Canada)...

Worm hormone discovery may aid fight against parasitic disease

Understanding the life of C. elegans
HOUSTON (April 4, 2006) When the nematode
Caenorhabditis elegans has enough to eat, enjoys the right temperatures and is not crowded out by its fellows, it produces a hormone, which binds to a receptor called DAF12 that allows it to reach reproductive maturity and live a natural lifespan. Wh...
