The paper develops a framework to predict microbial survival traits in spacecraft cleanrooms using metagenomics and machine learning, showing trait variability within taxa and the need for functional assessment beyond taxonomy.

This study examines how simulated Mars conditions affect immune responses to bacterial pathogens, finding altered cytokine secretion, ROS production, and phagocytic activity in human immune cells.

The study analyzes the microbial environment of the ISS, finding it similar to Earth's confined spaces, with microorganisms adapted to the extreme environment but not causing genomic changes relevant to human health.
