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 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)

DNA Damage And Survival Time Course Of Deinococcal Cell Pellets During 3 Years Of Exposure To Outer Space
The hypothesis called “panspermia” proposes an interplanetary transfer of life. Experiments have exposed extremophilic organisms to outer space to test microbe survivability and the panspermia hypothesis. Microbes inside shielding material […]
