Introducing Worm

In 1963 Sydney Brenner proposed to study the development of multi-cellular organisms using a genetic approach in a simple animal. He settled on a small, transparent nematode, Caenorhabditis elegans, which develops quickly and is anatomically simple with less than a thousand somatic cells. Almost half a century later there are many more researchers studying C. elegans than there are somatic cell...

Worm sensation!

Mechanosensation plays a pivotal role in many aspects of pain pathology, yet the mammalian molecular transduction apparatus responsible for this sensory modality remains unknown. In January's edition of Nature Neuroscience, O'Hagan, Chalfie and Goodman [1] have provided direct electrophysiological evidence that somatic mechanotransduction in C. elegans is mediated by a complex of proteins previ...

Worm Model

We present a method for tracking and distinguishing multiple C. elegans in a video sequence, including when they are in physical contact with one another. The worms are modeled with an articulated model composed of rectangular blocks, arranged in a deformable configuration represented by a spring-like connection between adjacent parts. Dynamic programming is applied to reduce the computational ...

WORM colorings

Given a coloring of the vertices, we say subgraph H is monochromatic if every vertex of H is assigned the same color, and rainbow if no pair of vertices of H are assigned the same color. Given a graph G and a graph F , we define an F -WORM coloring of G as a coloring of the vertices of G without a rainbow or monochromatic subgraph H isomorphic to F . We present some results on this concept espe...
