Inhabited subsurface wet smectites in the hyperarid core of the Atacama Desert as an analog for the search for life on Mars (2020) Azua-Bustos, Armando; Fairén, Alberto G.; González Silva, Carlos; Carrizo, Daniel; Fernández-Martínez, Miguel Ángel; Arenas-Fajardo, Cristián; Fernández-Sampedro, Maite; Gil-Lozano, Carolina; Sánchez-García, Laura; Ascaso, Carmen; ... (Nature Research, 2020-12-01)The modern Martian surface is unlikely to be habitable due to its extreme aridity among other environmental factors. This is the reason why the hyperarid core of the Atacama Desert has been studied as an analog for the ...
Can Halophilic and Psychrophilic Microorganisms Modify the Freezing/Melting Curve of Cold Salty Solutions? Implications for Mars Habitability (2020) Garcia-Descalzo, Laura; Gil-Lozano, Carolina; Muñoz-Iglesias, Victoria; Prieto-Ballesteros, Olga; Azua-Bustos, Armando; Fairén, Alberto G. (NLM (Medline), 2020-09-01)We present the hypothesis that microorganisms can change the freezing/melting curve of cold salty solutions by protein expression, as it is known that proteins can affect the liquid-to-ice transition, an ability that could ...
