Microorganisms in the human vagina, collectively referred to as the human vaginal microbiome (HVM), play fundamental roles in women’s health and their susceptibility to various urogenital diseases. For instance, bacterial vaginosis (BV), a common genital tract disorder in women, is characterized by an overgrowth of strict anaerobes over Lactobacilli, and is associated with an increased risk of acquiring sexually transmitted diseases (e.g.

In his 1989 book, Wonderful Life, Stephen Jay Gould proposed the following thought experiment: Rewind the tape of life and let evolution play out a second time. Does the replay produce anything like what we see today? In other words, is evolution reproducible, or do chance events (perhaps inconsequential at the time) cause evolutionary paths to diverge? Using experimental evolution, we can perform Gould's thought experiment in the laboratory by evolving hundreds of replicate populations.

Production of short-chain fatty acids (SCFAs) in the gut microbiome is required for optimal human health, but is frequently limited by the lack of fermentable fiber in the diet. We supplemented the diets of 174 young adults with different prebiotic fibers to determine the relationship between the supplements, the composition of the gut microbiota, and production of SCFAs.  Resistant starch from potatoes (RPS) resulted in the greatest increase in total SCFAs, including butyric acid – a SCFA with numerous beneficial effects.
