A Review on Hypothesized Metabolic Pathways on Europa and Enceladus: Space-Flight Detection Considerations

open access: yesLife, 2023
Enceladus and Europa, icy moons of Saturn and Jupiter, respectively, are believed to be habitable with liquid water oceans and therefore are of interest for future life detection missions and mission concepts. With the limited data from missions to these

Reactive oxygen species in the world ocean and their impacts on marine ecosystems

open access: yesRedox Biology, 2022
Reactive oxygen species (ROS) are omnipresent in the ocean, originating from both biological (e.g., unbalanced metabolism or stress) and non-biological processes (e.g. photooxidation of colored dissolved organic matter).
