Autonomous Multi-Agent Reconstruction of Prebiotic Reaction Networks Reveals Organizational Features of Amino Acid Synthesis
[chemrxiv.org] Decades of origin-of-life research have uncovered hundreds of prebiotically plausible reactions across hydrothermal, surface, and biochemical environments, yet this knowledge remains fragmented across chemistry, geochemistry, and astrobiology. Here we […]
