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.

A mathematical model shows how the shape of early multicellular organisms may have helped cells evolve specialized roles.

The Wtf4 antidote protein assembles with the Wtf4 poison protein and promotes the transportation of the assembled proteins to the vacuole for sequestration or destruction.

Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.

The principle underlying the appearance of the growth plate, an organ responsible for longitudinal growth, has implications for various cartilage pathologies including growth abnormalities in children, trauma and osteoarthritis.

A broad mutational target is the cause of the high mutational variance and corresponding fast phenotypic evolutionary rate in P3.p cell fate in Caenorhabditis nematodes.

The speed at which a cell fate decision in nematode worms evolves is due to the number of genes that control the decision, rather than to a high mutation rate.
