Mutations conferring resistance to Escherichia coli against the chemotherapy drug gemcitabine can have opposite effects on bacterial drug degradation and therefore can increase or decrease the chemotherapy load on neighboring cancer cells.

Genetic conflicts between sex chromosomes during spermatogenesis may drive the rapid evolution, function, and turnover of some sperm nuclear basic proteins in Drosophila species.

Key functional variants, discovered using Massively Parallel Reporter Assay (MPRA) and reporter assays in the context of SARS-CoV-2 infection, support the importance of two critical chemokine receptor genes CCR1 and CCR5 in severe Covid-19 illness.

The diversification of hand bones in mammals was much more dynamic than those of the proximal and intermediate forearm, involving higher morphological diversity, stronger integration, and greater evolutionary lability at distal structures.

Analysis of population diversity of SARS-CoV-2 revealed positive epistasis between sites carrying mutations characterizing rapidly expanding lineages.

Early-life exposure to conspecific urine and bedding extends the lifespan of female mice, indicating that social chemosensory cues can influence aging in a mammal.

The eggshells of palaeognath birds (e.g. ostrich, moa, kiwi, emu) have diverse homology and convergent features, and are useful modern analogues for the evolution of non-avian dinosaur eggshells.

Infants' vocalisations are contingent on their own stress physiology, and alter the inter-personal dynamics of how stress states are shared across the infant-caregiver dyad.

In bacteria, frequent adaptive copy-number mutations can hinder the fixation of beneficial point mutations and hence the divergence of duplicated DNA sequences.

Sloths, armadillos, and anteaters evolved genetic and cellular traits that make them remarkably cancer resistant.
