Molecular Biosignatures In Planetary Analogue Salts: Implications for Transport of Organics in Sulfate-rich Brines Beyond Earth

Salts formed during evaporation or freezing of brines can potentially incorporate organic matter that can inform about past biological activity. We analysed the lipid fraction preserved within the contemporary Lost […]
