Cells of the xanthophore lineage form projections that allow them to communicate with other pigment cells during adult pigment pattern formation in zebrafish, but not in the closely-related pearl danio.

A study of solute and macromolecule trafficking in plants reveals a previously undescribed route for carbon distribution in growing root tissues.

By thinking about experimental techniques in terms of six broad approaches – perturbation, visualization, substitution, characterization, reconstitution, and simulation – researchers may be able to generate more reliable inferences.

Research into light-gated ion channels called channelrhodospins laid the foundations for the development of optogenetics, a technique that has gone on to revolutionize neuroscience.

The gene regulation mechanisms necessary for the development of complex multicellular animals have been found in sponges.

The life cycle and morphology of the sea squirt Ciona intestinalis shed light on vertebrate evolution.

Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.
