Regulation of conserved Nodal factors by a maternal protein ensures that Nodal signaling is repressed until the appropriate time in embryonic development.

A long non-coding RNA molecule called cherub is a driver of tumor development.

The deer mouse (Peromyscus) has emerged as a model system for studying many aspects of biology, supported by extensive historical knowledge of its fascinating and varied natural history.

We discuss the methods available to understand lncRNA function in vivo, and highlight important considerations that should be taken into account when designing such experiments.

A motor protein called Klp10A ensures that germline stem cells in male fruit flies divide to produce two sibling cells that are equal in size.

Selective synapse formation in a retinal motion-sensitive circuit is orchestrated by starburst amacrine cells, which use homotypic interactions to initiate formation of a dendritic scaffold that recruits projections from circuit partners.
