Dust storm-driven Dispersal of Potential Pathogens and Antimicrobial Resistance Genes In The Eastern Mediterranean
The atmosphere hosts a microbiome that connects remote ecosystems but remains underexplored. In this study, we employed metagenomics to examine the ecological roles of the atmospheric microbiome, including the dispersal […]

The COSPAR Planetary Protection Policy for Missions to Icy Worlds: A Review of History, Current Scientific Knowledge, And Future Directions
Recent discoveries related to the habitability and astrobiological relevance of the outer Solar System have expanded our understanding of where and how life may have originated. As a result, the […]
![The age and configuration of the known planets in putative, icy exomoon-bearing Jupiter-like gas giant consisting of candidate exosystems. The size of the bubbles indicates the mass of the planets in MJup. The dotted, dashed, and solid black curves in the upper right corner of the plot show the estimated impact ratio in the case of Late Heavy Bombardment and are used as an indicator of higher probability bioaerosol ejection in space 28 (steady decrease impact flux: dotted and dashed lines, and single cataclysm - sensu stricto Late Heavy Bombardment: solid line scenarios) [51]. I.e. the curves may show the changing tendency in the probability of bioaerosol ejection and transportation in the case of various exosystems in the period marked by the transparent grey horizontal regions. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/06/Searching-For-Jupiter-And-Saturn.png?resize=1200%2C721&ssl=1)

A Comparative Ultrastructure Study of the Tardigrade Ramazzottius varieornatus In The Hydrated State, After Desiccation and During the Process of Rehydration
Tardigrades can survive hostile environments such as desiccation by adopting a state of anhydrobiosis. Numerous tardigrade species have been described thus far, and recent genome and transcriptome analyses revealed that […]

Cosmic Dust Fertilization Of Glacial Prebiotic Chemistry On Early Earth
Earth’s surface is deficient in available forms of many elements considered limiting for prebiotic chemistry. In contrast, many extraterrestrial rocky objects are rich in these same elements. Limiting prebiotic ingredients […]
