Viral challenges and adaptations between Central Arctic Ocean and atmosphere

The paper studies viral diversity and adaptations in Central Arctic Ocean and atmosphere, finding that viruses use strategies to survive in extreme environments and that the air-sea interface plays a role in viral distribution.

Ecogenomics reveals distinctive viral-bacterial communities in the surface microlayer of a natural surface slick

The paper investigates viral and bacterial communities in slick and non-slick sea-surface microlayers, finding distinct viral communities and metabolic profiles in slicks.

Virus-host dynamics in archaeal groundwater biofilms and the associated bacterial community composition

The paper studies virus-host dynamics in archaeal groundwater biofilms over three years, finding a steady increase in viral infections and a stable bacterial community dominated by Desulfobacterota.

Co-evolutionary patterns shown in Ostreococcus-virus system from the Western Baltic Sea in freshly isolated hosts and viruses.

The paper examines co-evolutionary patterns between Ostreococcus hosts and their viruses in the Western Baltic Sea, showing that coexistence timing drives infection patterns and highlights species-specific co-evolution.

Heads in the clouds: marine viruses disperse bidirectionally along the natural water cycle

The paper shows marine viruses disperse bidirectionally between air-sea interface ecosystems and rainwater, with genetic evidence of virus-host interactions and implications for atmospheric processes.

Host-associated phages disperse across the extraterrestrial analogue Antarctica

The paper tracks host-associated phages across Antarctica using metagenomic data, finding long-distance dispersal of Ralstonia phages with implications for Astrobiology and Planetary Protection.

Sea foams are ephemeral hotspots for distinctive bacterial communities contrasting sea-surface microlayer and underlying surface water

The paper examines bacterial communities in sea foams, finding they differ from the sea-surface microlayer and underlying water but contain SML bacteria, suggesting foam formation is influenced by surface habitats.

Virus-associated organosulfur metabolism in human and environmental systems

This study identifies 39 viral gene families involved in organosulfur metabolism across diverse ecosystems, showing their role in sulfide production and viral fitness.

Diverse viruses carrying genes for microbial extremotolerance in the Atacama Desert hyperarid soil

The paper identifies diverse viruses in Atacama Desert soils that carry genes for microbial extremotolerance, suggesting a mutualistic role in host survival under extreme conditions.

Genome-informed microscopy reveals infections of uncultivated carbon-fixing archaea by lytic viruses in Earth's crust

The paper uses genome-informed microscopy to show lytic viruses infect uncultivated carbon-fixing archaea in Earth's crust, challenging previous assumptions about viral lifestyles in subsurface ecosystems.

Short-term responses to ocean acidification: effects on relative abundance of eukaryotic plankton from the tropical Timor Sea

This study examines the effects of ocean acidification on eukaryotic plankton communities in the Timor Sea, showing reduced abundance of key species under high CO2 conditions.

Geological degassing enhances microbial metabolism in the continental subsurface

This study investigates how mantle degassing affects microbial metabolism in deep subsurface environments, finding that gas-rich sites show increased microbial activity compared to non-impacted sites.
