In the lightless depths of the Earth, microorganisms have long practiced a form of survival that defies our familiar biological intuitions—drawing life not from sunlight but from the slow chemistry of rock and mineral. German researchers have now illuminated one of the most elegant mechanisms in this hidden world: an enzyme called DAB2 that captures carbon dioxide and converts it to bicarbonate using nothing more than the electrical charge across a cell membrane, bypassing the ATP that nearly all other life expends for the same task. This discovery, born from the study of sulfur-loving bacteri
