Gut bacteria ammonia production restores acetylcholine neurotransmission and bowel motility Nature Microbiology, Published online: 26 February 2026; doi:10.1038/s41564-026-02292-9Acetylcholine levels are reduced in gut dysmotility conditions. We find that gut acetylcholine levels induce a compensatory increase in gut microbiota urease activity and ammonia production. By upregulating presynaptic Cav2.1 calcium channels in enteric neurons, ammonia enhances calcium influx and restores acetylcholine release neurotransmission, revealing a microbiota-driven mechanism that preserves gut motility.

Metabolic modeling reveals determinants of prebiotic and probiotic treatment efficacy across multiple human intervention trials Prebiotic and probiotic interventions can induce therapeutically relevant shifts in the human microbiome, but their effects are variable across individuals. This study shows that metabolic models can ...

Untargeted longitudinal ultra deep metagenomic sequencing of wastewater provides a comprehensive readout of expected and unexpected viral pathogens Wastewater surveillance has become a powerful tool to monitor circulating viruses at a community level. Currently, most wastewater surveillance efforts use target-based approaches such as quantitative...

Can you take a quarter cup of composite sewage, simply ask ‘what’s in there?’, and find out all of the pathogens circulating in that community?

That is the question we asked in our latest pre-print.

Turns out you can.
