Meta-analysis reveals there is no evidence that variation in clutch size in birds is driven by the reproduction–survival trade-off.

Fitness defects arising from deletion of the gene encoding the bacterial equivalent of actin (mreB) are readily compensated by mutations affecting cell wall synthesis.

DNA hypomethylation in human tumor cells results in the activation of the LINE-1-derived RNA-binding protein L1TD1 and its interactions with LINE-1 transposons.

After their introduction to the Iberian peninsula, domestic cattle hybridised with mostly male wild aurochs for millennia until human actions likely ended this process about 4000 years ago.

Using single-cell RNA sequencing, we mapped thousands of expression quantitative trait loci in yeast, including a variant in GPA1 that influences gene expression, cell-cycle occupancy, and mating efficiency.
