New morphological information on the Cambrian artiopodan Acanthomeridion, including CT data, demonstrate that dorsal ecdysial sutures likely evolved multiple times within this group.

Activity in the hypothalamic dorsal premammillary nucleus predicts future escape from threat, represents escape velocity, and controls escape velocity via a projection to the brainstem.

Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.

The ancestor of all known jawed vertebrates possessed a maxilla and premaxilla and was similar in morphology to the 'maxillate placoderms' from China.

Live imaging coupled with cell lineage tracing in chick and mouse embryos reveal that the cardiac regulatory gene Nkx2.5 is also transiently expressed in early extra-cardiac hemogenic angioblasts that migrate to the heart, yolk sac and dorsal aorta.

Patterning of the dorsal-ventral axis in zebrafish is mediated by a graded source-sink mechanism in which diffusing BMP, produced from a ventrally biased source, is inhibited by dorsally-produced chordin.

A novel method of recording neural activity from the rodent medial prefrontal cortex reveals that the medial prefrontal cortex is composed of functionally distinct subregions that process economic decision information differentially along a dorso-ventral gradient.

Functional neuroimaging reveals sensitivity to shape information and correlation between brain activation and perceptual behaviour in both dorsal and ventral visual pathways, thereby challenging the strict binary distinctions between the two pathways.

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