A Hybrid Iron/Green-Rust-Urea Model for Prebiotic Chemistry: A Synthesis of Testable Pathways for Planetary Astrobiology
We propose a quantitative, testable framework for abiogenesis that links submarine alkaline vents, which supply H2, ΔpH, and Fe/Fe–S catalysis, to subaerial hot-spring fields that provide wet–dry concentration and UV-driven […]

Variability Due To Climate And Chemistry In Observations Of Oxygenated Earth-analogue Exoplanets
The Great Oxidation Event was a period during which Earth’s atmospheric oxygen (O2) concentrations increased from ∼10−5 times its present atmospheric level (PAL) to near modern levels, marking the start […]
