The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.

Analysis of 108 human embryos aged 3–7 weeks reveals modes of primary and secondary neurulation, regulation of body elongation, somite formation rate, and common occurrence of a split neural tube.

Characterization of an abundant clonogenic and multipotent population of immature neuroblasts, at the transition between transient-amplifying progenitor (TAP) neuroblasts and migratory neuroblasts, reversibly engaged in neuronal differentiation.

FMNL1β is phosphorylated on S1086 in a protein kinase C δ (PKCδ)-dependent manner and S1086-phosphorylated FMNL1β acts downstream of PKCδ to regulate centrosome and multivesicular bodies polarization to the immunological synapse and exosome release.

A single-cell RNA sequencing reveals cell heterogeneity of secondary metabolism in tea plant root and a proposed model in which the theanine biosynthesis pathway occurs via multicellular compartmentation.
