For an animal to develop normally, cells must not only become the right types but also do so at the right time. In the worm C ...

MicroRNAs are small non-coding RNAs that guide post-transcriptional repression by base-pairing to target messenger RNAs. First discovered in Caenorhabditis elegans, they orchestrate the precise timing ...

The existence of small-molecule signals that influence development in Caenorhabditis elegans has been known for several decades, but only in recent years have the chemical structures of several of ...

Researchers have developed a new imaging technique to observe active gene expression in real time. They found that four molecules work together to control the timing of each stage of the C. elegans ...
