In this issue of Cell Host & Microbe, Reitmeier et al. (2020) employ timestamped gut microbiome sequencing data from human subjects coupled with machine learning to identify microbial rhythmicity patterns that predict Type 2 Diabetes incidence.The story of twentieth century biomedical breakthroughs could be told through cholesterol. Revolutions in genetics, molecular biology, genomics, and antibody-based therapies defined cholesterol's impact on human health and cholesterol-lowering strategies. In this issue, Kenny et al. (2020) bring a key twenty-first century biomedical development-the microbiome revolution-to cholesterol.Human milk harbors its own microbiota, but whether the microbes seed the infant gut and are modified by breastfeeding practices is unresolved. In this issue, Fehr et al. (2020) sequence breastmilk and infant stool samples from mother-infant dyads to investigate the co-occurrence of milk-gut bacteria and the impact of breastfeeding practices.In this issue of Cell Host & Microbe, Adebayo et al. (2020) examine the urobiome of older community-dwelling women within the TwinUK Cohort. They define a core genitourinary microbiome for older women with many heritable microbial taxa. Some taxa appear to co-occur, suggesting the existence of specific microbial consortia.Every animal is in constant communication with populations of microbes. In a recent study, O'Donnell and colleagues (2020) uncover an inter-domain conversation, defining a relationship in which a non-pathogenic microbe directly synthesizes a signal that alters host behavior for a mutually beneficial outcome. Almost a third of those undergoing knee replacement for osteoarthritis have poor outcomes despite technically successful surgery. Preoperative neuropathic-like pain and/or pain sensitisation may increase the risk of pain follow
