Congratulations to Dr. Carolina Tropini for her recent review The gut microbiota and its biogeography in Nature.

In the past few years, scientists have been using more advanced techniques to study the microorganisms living in our gut. These techniques have revealed a great diversity of these microorganisms and helped us understand how they are distributed throughout the gut.

One key finding in this review is how some microorganisms are enclosed in mucus, and scientists have been able to measure and identify various bacterial species in different parts of the gut. This review focuses on the new insights gained about the distribution and diversity of gut microorganisms, thanks to these advanced observational methods.
