Human gut bacteria alter their metabolism in response to each other's presence, which causes their community dynamics to deviate from predictions that are based on mono-culture data.

Longstanding eco-evolutionary theories are tested using shotgun metagenomic data from the human gut microbiome, showing links between community diversity and the evolutionary trajectory of a focal species within the community.

Lactobacillus plantarum regulates host uric acid metabolism via its own nucleoside hydrolase iunH.

Experiments in ex-germ-free mice establish a measurable effect of colonization history on gut microbiota assembly, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities.

In the fruit fly Drosophila melanogaster, stem cell activity ages female guts but not male guts; furthermore, males with feminized guts develop pathologies but gain an increase in lifespan through dietary restriction.

Recurrent neural network models enable prediction and design of health-relevant metabolite dynamics in synthetic human gut communities.

Expression of two highly regulated subfamilies of the complex multigene family encoding IL-17 cytokines in the purple sea urchin are sequentially activated in a larval gut-associated inflammation model and modulate downstream gene expression in the gut epithelium.

Gut microbial signatures of domestication parallel those of industrialization, implicating shared ecological drivers.

Bioinformatics analyses and experiments in mouse models reveal how Escherichia coli accesses the molecular hydrogen pool to boost colonization during acute colitis.

Calcineurin inhibition has opposing effects on Caenorhabditis elegans lifespan and survival on pathogens via its role in the defecation motor program.
