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.

Genomic characterization of Microbacterium meiriae sp. nov., a novel bacterium isolated from the International Space Station [PDF]

open access: yesScientific Reports
During the microbial surveillance of the International Space Station (ISS) in April 2018, four Gram-stain positive bacterial strains, designated as F6_8S_P_2BT, F6_8S_P_3A, F6_8S_P_3B and F6_8S_P_3C, belonging to the genus Microbacterium were isolated ...

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.

Astrobiology in Space: A Comprehensive Look at the Solar System

open access: yesLife, 2023
The field of astrobiology aims to understand the origin of life on Earth and searches for evidence of life beyond our planet. Although there is agreement on some of the requirements for life on Earth, the exact process by which life emerged from ...

Adaptations of endolithic communities to abrupt environmental changes in a hyper-arid desert

open access: yesScientific Reports, 2022
The adaptation mechanisms of microbial communities to natural perturbations remain unexplored, particularly in extreme environments. The extremophilic communities of halite (NaCl) nodules from the hyper-arid core of the Atacama Desert are self-sustained ...
