A gene regulatory network model provides a simplified explanation of the molecular interactions that orchestrate muscle development in the sea urchin embryo.

A shift in antero-posterior positional information may contribute to the fin-to-limb transformation.

Experimental mapping of the joint sequence space of an ancient transcription factor (TF) and its DNA binding sites reveals that epistasis across the molecular interface permitted the evolution of a new and specific TF-DNA complex.

In-lab evolution of synthetic promoters has revealed a novel general mechanism for de novo evolution of gene regulation, and highlights the crucial role of expression noise in this process.

The overexpression of RNA chaperones, including several DEAD box RNA helicases, enhances the fitness of mutationally compromised E. coli strains.

Studies of the house mouse Mus musculus have provided important insights into mammalian biology, and efforts to study wild house mice and to create new inbred strains from wild populations have the potential to increase its usefulness as a model system.

Genomic evidence suggests that L-gulonolactone oxidase-the terminal enzyme in vitamin C synthesis, which has been repeatedly lost throughout animal evolution-was lost in plants and other photosynthetic eukaryotes following plastid acquisition.

Genetic architecture governs the evolvability of adaptive paths providing a framework for evolutionary forecasting.

The discovery of the earliest direct evidence of brood care in insects demonstrates a remarkably conserved egg-brooding reproductive strategy within scale insects in stasis for nearly 100 million years.
