Cis-regulation such as enhancers and promoters plays a major role in parallel gene expression divergence and has features that make it a well-poised substrate for adaptive evolution.

Zebrafish provide unique resources for the study of the tumor microenvironment.

Experimental manipulations of social groups of ostriches show that the benefits of cooperative parental care for females, and the costs of sexual competition for males, lead to sex differences in optimal group sizes.

A CRISPR-based dual reporter assay enables genetic mapping of DNA variants that specifically affect mRNA or protein levels in trans.

The application of long-read sequencing to the pea aphid wing dimorphism system reveals genomic structural divergence as a genetic mechanism of adaptation.

An unbiased chemical screen identifies the AAA+ membrane metalloprotease FtsH1 as a novel apicoplast biogenesis factor and druggable antimalarial target.

Genome engineering and phenotyping in vivo reveal surprising new features of adaptive amino acid substitutions that were previously inaccessible.

Sampling informed by pathogen genomic data may facilitate more efficient detection of novel antibiotic resistance than random sampling.

Evidence that C. elegans and mammals use homologous versions of the same protein (RIG-1) to activate antiviral defense mechanisms suggests that RIG-1 may have a conserved role in coupling virus recognition to virus destruction.

A new method to infer the spatial history of genetic ancestors from a sequence of trees along a recombining genome.
