Heterochromatic sequences evolve rapidly, as do ZAD-ZNF genes-encoding proteins involved in heterochromatin functions, explaining why evolutionarily dynamic ZAD-ZNF genes are more likely to be essential in Drosophila.
A novel assay to measure 2-micron stability together with a survey of natural variation among Saccharomyces cerevisiae strains reveals novel means by which yeasts can combat the parasitic 2-micron plasmids.
Similar evolutionary pressures on gene expression between human and chimpanzee populations contribute to the observation that inter-individual gene expression variability is similar across genes in these species.
A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.
Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.
Poison acidified crops sanitize food and limit disease transmission while at the same time structuring the gut microbiota and thus contribute to the ecological and evolutionary success of formicine ants.
