In C. elegans, dauer pheromone is an indicator of population density and influences pathways that regulate metabolism, development, and aging. In a recent publication in Nature, Paik and coworkers (Jeong et al., 2005) show the purified substance to be a pyran ring conjugated to heptanoic acid, setting the stage for dissecting downstream signaling pathways.

Insulin/IGF signaling has emerged as a central regulator of metazoan aging. In C. elegans, insulin-like peptides are expressed predominately in neurons. Alcedo and Kenyon demonstrate that removal of specific gustatory and olfactory neurons result in longer life, suggesting that metazoan longevity is influenced by sensory perception.

Aurora A kinase is a key regulator of cell division, whose functions were attributed to its ability to phosphorylate diverse substrates. Aurora A is now shown to have a kinase-independent role in the regulation of chromatin-mediated microtubule assembly.

As a microtubule-organizing center, the centrosome undergoes a dramatic increase in size - via expansion of the pericentriolar material - during mitosis. Recent work reveals shared assembly properties of a protein scaffold that facilitates and supports this expansion, a process critical to spindle assembly.

Li et al. demonstrate that a single interneuron can regulate analog- and digital-like behaviors guided by two different postsynaptic neurons. Releasing a single neurotransmitter onto downstream neurons that express receptors with distinct biophysical properties enables a small set of neurons to direct a range of functional responses.
