The life below our feet: team discovers microbes thriving in groundwater and producing oxygen in the dark

A team of scientists has discovered ancient groundwaters harbor diverse microbial communities producing large amounts of 'dark oxygen'. This process enables microbes to survive and potentially consume methane, a greenhouse gas. The study's findings challenge prior assumptions about microbial life in subsurface ecosystems.
