Forging the iron‐net: Towards a quantitative understanding of microbial communities via siderophore‐mediated interactions Iron is a critical yet limited nutrient for microbial growth. To scavenge iron, most microbes produce siderophores—diverse small molecules with high iron affinities. Different siderophores are specif...

Gut microbiota regulates stress responsivity via the circadian system Gut microbes are known to modulate stress responsivity and behavior. Tofani et al. demonstrate that such modulations occur via the circadian system. The oscillations in gut microbiota composition regu...

Pulled together this starter pack for Microbiota-Gut-Brain Axis Research.
🧠🦠🥼

Hope it is helpful for the people joining in here and nucleating a community.

May have missed people, please leave a reply and I can then add to the pack.

Cheers.

1/ Keen to share the story of my postdoc research out in @natureportfolio.bsky.social! We built a massive resource characterizing the spatial landscape of the gut—and yes, we dug deep into the biology too. If you’ve got a minute, let me walk you through the story. 🧵👇

Interestingly, single housing didn't have much of an effect at all.
