OoL digest — November 15th edition
Four new papers and one book preprint this week in astronomy/astrobiology and biochemistry.
Astronomy/astrobiology: Bains summarizes the Venusian PH$_3$ discovery and its scientific debate, Byrne introduces a new predicted exoplanet category with a brittle outer layer, Cockell discusses the implications of binary/continuous habitability metrics, and the National Academies of Sciences announces a preprint of their Pathways to Discovery in Astronomy and Astrophysics for the 2020s that identifies science goals for the next decade.
Biochemistry: Cesur discusses microbial growth in deliquescent brines and its implication as a contamination to Mars.
