From Exobiology to Cosmobiology at LISA and Elsewhere.

open access: bronzeBiological Sciences in Space, 1998
Since the emergence of Exobiology, back to the l960ties, this field drastically increased and, although differently named, is today a largely recognized scientific domain of wild interdisciplinarity. It includes not only the search for extraterrestrial living Systems, in particular by direct exploration of planetary bodies and studies of ...

Heterogeneity of rock-hosted microbial communities in a serpentinizing aquifer of the Coast Range Ophiolite [PDF]

open access: yesFrontiers in Microbiology
The movement of groundwater through fractured bedrock provides favorable conditions for subsurface microbial life, characterized by constrained flow pathways and distinctive local environmental conditions.

Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The Abundance and Diversity of Fungi in a Hypersaline Microbial Mat from Guerrero Negro, Baja California, México

open access: yesJournal of Fungi, 2021
The abundance and diversity of fungi were evaluated in a hypersaline microbial mat from Guerrero Negro, México, using a combination of quantitative polymerase chain reaction (qPCR) amplification of domain-specific primers, and metagenomic sequencing ...

Electrophysiological Properties from Computations at a Single Voltage: Testing Theory with Stochastic Simulations

open access: yesEntropy, 2021
We use stochastic simulations to investigate the performance of two recently developed methods for calculating the free energy profiles of ion channels and their electrophysiological properties, such as current–voltage dependence and reversal potential ...

Self-Similar Patterns from Abiotic Decarboxylation Metabolism through Chemically Oscillating Reactions: A Prebiotic Model for the Origin of Life

open access: yesLife, 2023
The origin of life must have included an abiotic stage of carbon redox reactions that involved electron transport chains and the production of lifelike patterns.

Development of non‐destructive analytical strategies based on Raman spectroscopy and complementary techniques for Mars Sample Return tested on Northwest Africa 1950 Martian meteorite

open access: yesJournal of Raman Spectroscopy, Volume 53, Issue 12, Page 2068-2085, December 2022., 2022
A non‐destructive analytical methodology, based on Raman microscopy (single point and imaging), micro‐energy dispersive X‐ray fluorescence (μED‐XRF) imaging analysis, and scanning electron microscopy coupled to energy dispersive spectroscopy (SEM‐EDS), is suggested for a first analytical characterization for the Martian samples that will be taken to ...
