Secretion and fibrillogenesis of collagen-I are separately controlled molecular pathways in the fibroblast, where surprisingly endocytic recycling is required for fibril formation and is increased in fibrotic fibroblasts.

Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.
Measurements of transcript isoform specific translation across the human genome reveal that isoforms from the same gene can differ in protein production by two orders of magnitude.
Temporally delayed linear modelling provides a domain-general linear framework for sequence detection and statistical testing, and is able to detect replays in both human neuroimaging and animal electrophysiology.
The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

Mechanisms that regulate RNA localization in one cell type predictably regulate RNA localization in other cell types, even if they have vastly different morphologies, implying an underlying regulatory code that cuts across specific subcellular structures.
A 3D model captures the growth and expansion dynamics of bacterial colonies, revealing distinct effects of surface tension, mechanical forces, and nutrients on the speed of radial and vertical expansion.

A retracting gradient of the transcription factor Tailless spatiotemporally patterns the Drosophila tail region by modulating the intrinsic dynamics of a regulatory network involving the timer genes caudal, Dichaete, and odd-paired.
