Vaginal pH Redux: Primate Vaginal Microbial Communities and Your Health

ecoli sq

In parts 1 and 2 of the vaginal pH redux, I have of course spent the majority of my time discussing vaginal acidity. You might have noticed a layer of the conversation beginning to assert itself, though, concerning vaginal microbial communities, or vaginal flora. The interplay between the composition of the vaginal microbial community and [...]

In my last post I covered the safety and efficacy of acid-promoting tampons. Marc Abrahams, of Annals of Improbable Research and Ig Nobel fame, sent me an article about the intravaginal use of lime juice to prevent HIV by Nigerian women. The particular paper he sent me (Mauck et al. 2008) provided a fairly rigorous [...]

SciAmChem: Don’t douche, she declares acidly

Frucht der Edelkastanie

In high school, I enjoyed participating in the science fair. I chose fairly random topics each year, but I do remember the year I studied the pH of soil and its impact on the color of flower petals. I grew a small set of African violets for a few weeks, then ground up their petals [...]

What’s the best idea for reducing the impacts of ocean acidification on the environment and society? After all, carbon dioxide levels in the atmosphere continue to go up and up and up, which suggests that the pH of seawater will continue to fall and fall and fall. The Paul G.
