The gene regulatory network controlling directed cell migration in a sea urchin is strikingly similar to a sub-circuit for eye development in Drosophila, suggesting that ancient systems-level controls may be adapted for diverse functions in different animals.

Activator of G-protein signaling C-terminus serves as a variable element to induce asymmetric cell division, facilitating developmental diversity among species.

Light and X-ray scattering on the same primate and human brain samples cross-validate each other and enable accurate mapping of axonal trajectories in regions with uni- and multi-directional nerve fibers, which can be used to validate diffusion MRI.

Apicomplexan parasites secrete proteins to manipulate their hosts from sub-apical openings in their cell pellicle that are distinct from the apical complex from where invasion factors are secreted.

A new electron diffraction technique called MicroED allows protein structures to be determined from three-dimensional microcrystals.

Myristoylation of a secreted protein, identified in a global myristoylation analysis of the eukaryotic parasite Toxoplasma gondii, is important for host cell invasion.

During early embryogenesis of the sea urchin, asymmetrical positioning of the dorsal/ventral organizer relies upon the suppression of organizer activities in dorsal blastomeres by the Hbox12 homeodomain-containing repressor.

A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.

Confined magnetotactic bacteria exhibit circling and U-turn trajectories explained by a competition of alignment with a magnetic field and alignment along the confining walls as well as considerable cell-to-cell heterogeneity.
