When an essential metabolic gene in E. coli is mutationally inactivated, subsequent evolution rarely reverts the mutation to wild type but rather follows unexpected paths that rewire metabolic fluxes.

A lexicon to help scientists and philosophers discuss the meaning of function in molecular biology more clearly is proposed.

Bacteria growing in biofilms evolve antimicrobial resistance via different pathways and generate greater genetic diversity than well-mixed populations, selecting fitter but less resistant genotypes.

The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.

We are writing to comment on the article by Chen et al. (2018) about inter-nucleus recombination in arbuscular mycorrhizal fungi.

A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.

Using different sets of input sequences to evolutionary reconstruction algorithms results in the exploration of many possible models, the intergration over which produces significantly more accurate models.

De novo formation of centromeres creates diverse karyotypes in flies and is accompanied by rapid turnover of centromere-associated satellite repeats.

Fog signaling with a narrow morphogenetic role in Drosophila has a deeply conserved function in epithelial morphogenesis across insects.

A new study upturns the long-held belief that in fruit flies, the yellow gene determines sex-specific behaviors by acting in the brain.
