Story summary

University of Bremen scientists found unexpected biosignatures in blue volcanic goo from mud volcanoes near the Mariana Trench.
The sediment contains fats from extremophile microbes thriving in high-pH conditions and deriving energy from methane by consuming sulfate.
The study, published in Communications Earth & Environment, confirms methane-producing microorganisms had been assumed but not verified.
The findings deepen understanding of life in extreme environments and inform Earth's nutrient cycles.
