Mutations that directly benefit both self and cooperative partner can readily evolve to promote cooperation.

Annual crop communities are able to adapt towards reduced competition and/or increased facilitation in response to their neighboring diversity after only two generations.

The rate of DNA unwinding by RecQ helicases is dramatically modulated by the DNA duplex stability in a geometry-dependent manner, providing an intrinsic mechanism for suppressing illegitimate recombination.

Quorum-sensing control of Burkholderia thailandensis toxin and immunity pairs serves to police quorum-sensing mutants and may represent a general strategy whereby cooperators can police mutants.

Molecular details of how the iron–sulfur cluster cofactor of a bacterial global iron regulatory protein simultaneously senses iron and O₂ are revealed by mass spectrometry and spectroscopy.

With mathematical modeling being an important source of insight for microbial communities, we may need to move beyond commonly-used pairwise models that do not capture microbial interactions.

The formation of new neurons in the adult dentate gyrus causes a proportion of cortical neurons to transfer their existing connections to the newborn cells.

Food supply and nutrient stress tolerance coordinately shape the multilevel selection dynamics of a mitochondrial cheater by promoting cheater persistence at both within-host and between-host levels of selection.

Using novel approach to study real-time social interactions shows that mutual action visibility facilitates static and dynamic coordination in both species, but whereas humans employ dynamic turn-taking to equalize rewards, macaques, after training with a human, compete between themselves.

Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.
