Genetic conflicts between sex chromosomes during spermatogenesis may drive the rapid evolution, function, and turnover of some sperm nuclear basic proteins in Drosophila species.
Wnt/beta-catenin signaling is essential for the specification of dorsal cell fate in amphioxus, suggesting a common evolutionary origin for the formation of the dorsal organizer in chordates.
Serial-section EM analysis uncovers the CNS connectome of a Ciona larva, the second of any entire nervous system, and exposes left-right asymmetries in its synaptic circuits.

Cell assemblies can use environmental cues created by their own respiration, such as oxygen gradients, to collectively guide themselves to more favorable locations in a remarkably robust and long-lasting way.
The slope of the chemoattractant concentration gradient is a driving force for sperm chemotaxis, by coordinating the entrainment of information flow between sensing, signaling and motility.

Developmental regulatory mechanisms for peripheral nervous system formation appear to be conserved in ascidians despite extensive genomic divergence after 390 MY of separate evolution.

Live imaging of multiple cytoplasmic networks in frog egg extracts calls for new models for how egg cytoplasm is physically organized during cleavage divisions.
