The tooth shape of sharks and mice are regulated by a similar signaling center despite their teeth having very different geometries.

The underlying neurophysiology of the lateral line system in blind cavefish (Astyanax mexicanus) has evolutionarily converged on elevated afferent neuron activity and partial loss of function in inhibitory efferent neurons, both of which contribute to enhanced sensitivity to flow stimuli.

Genetic barriers to gene flow maintain divergent linked substitution rates in hybridization.

Joint sequence, structure, and phylogenetic analyses identify highly conserved features in transmembrane domains of transient receptor potential (TRP) ion channel proteins that offer a novel explanation for how TRPs could integrate stimuli into cellular signals.

Lineage tracing and genetic analysis in zebrafish show that the pseudobranch is a serial homolog of the gills arising from the jaw-forming mandibular arch, thus supporting the model that vertebrate jaws derived from an ancestral mandibular gill.

Populations of Mycobacterium tuberculosis associated with clustering and shorter terminal branches are not necessarily transmitting more.

The dominant MRSA circulating in European livestock has stably maintained genes associated with resistance to antibiotic treatments over several decades and when it is transmitted to humans it can rapidly acquire genes that allow it to evade human immune responses.

Integration of evolutionary dynamics framed through a mathematical model improved outcomes in abiraterone monotherapy for the treatment of metastatic castrate-resistant prostate cancer.

Ancestral reconstruction of a signaling pathway reveals the mutations responsible for producing specificity of the two paralogous pathways produced by a duplication event.

Selection acting on SARS-CoV-2 variants altering the infectivity profile depends on levels of transmission in the community, and this dependence is used to infer Alpha and Delta variants infectivity profiles.
