Poor replicability in animal research can be a result of low external validity driven by rigorous standardization of study populations. This study investigates how heterogenization of study populations by using mice from different breeding sites might affect the replicability of animal studies conducted in a single facility. The findings suggest that heterogenization by breeding site has limited capacity to improve replicability in animal research.

Imbalance in the growth rate of two organs can perturb their appropriate scaling. Here, Stojanovski et al., identify a mechanism involving the mechanotransducer YAP-1 which ensures proper proportions of the pharynx and the body length of C. elegans.

How cells shape signalling dynamics in MAPK cascades remains unclear. Here the authors combine mathematical modelling with in vivo validation to uncover a novel feedback mechanism that increases processivity and robustness of the yeast Hog1 module.

Genotype networks are sets of genotypes connected by small mutational changes that share the same phenotype. Here the authors combine construction of over 20 synthetic gene regulatory networks with mathematical modeling to exemplify how gene regulatory networks provide robustness in face of mutations while enabling transitions to innovative phenotypes.

A feedback loop involving non-muscle myosin II and Rho-associated protein kinase I provides a robust mechanism for stabilizing epithelial junctions.
