The paper identifies genome-wide selective sweeps in the human gut microbiome, revealing ecologically distinct populations linked to age and colorectal cancer.

The paper shows that individuals vary in their gut microbiota's ability to ferment dietary fibers, leading to different SCFA production, and suggests personalized fiber supplementation as a therapeutic strategy.

This paper introduces MicrobiomeCensus, an algorithm to estimate human population size from sewage samples using microbial taxon abundance distributions, showing it outperforms generic algorithms in simulations and field data.
