Life is ubiquitous not only in the near-surface environment where sunlight is converted into biological energy via photosynthesis, but also in the deep-sea and subsurface associated with chemical fluxes that sustain chemosynthesis. The present litho-hydro-bio-sphere has been shaped, at least in part, by intricate and diverse interplays between minerals and life forms in aqueous systems. Recent advances in technology that enables us to grasp nanometer-scale mineralogical features and to identify invisible microorganisms on the basis of their DNA sequences. As a consequence, the occurrence of, and mechanisms for, the biological formation and dissolution of many mineral phases have been unveiled. Several works that exemplify the progress in mineral-water-life interactions are presented in this short article.
