OoL digest — November 22nd edition

Four new astrobiology papers: effects of flares on M-earths habitability (Bogner), false positives for biosignatures on Mars (McMahon), effects of clouds on CH$_4$-CO$_2$ detection with JWST (Mikal-Evans) and a technosignature signal from Proxima Centauri (Smith). In biochemistry, Vincent discusses the prebiotic soup ingredients, in bioinformatics Okauchi examines cell-free replication and evolution and in planetary science Villafañe-Barajas analyzes the relevance of dynamic systems in hydrothermal vent systems.
