NEWS December 2024
The year 2024 was scientifically great. Probably the most satisfying was the publication of Chloé Truong’s three articles on the role of pyrite minerals in the adaptation of hyperthermophilic microorganisms to their highly mineralized hydrothermal environment. And the best news was the award of the Haüy-Lacroix Mineralogy Prize from the Société Française de Minéralogie Cristallographie to Chloé’s thesis work.

Recently published 3 hopefully important papers : Antonin Affholder, François Guyot, Boris Sauterey, Régis Ferrière and Stéphane Mazevet (2021) Bayesian analysis of Enceladus’ plume data to assess methanogenesis. Nature Astronomy, 2021/6/7, 1-10 What I find important in this article, beyond the quantitative estimation of the likelihood of the presence of life with metabolic methanogenesis in…
