This paper reconstructs microbial communities from 2-million-year-old permafrost in Greenland, finding similarities to modern thawing permafrost microbes and suggesting microbial communities may signal climate change impacts before plants and animals.

This study investigates how giant viruses adapt to polar ocean environments by analyzing their biogeography and functional genes, finding that their adaptation is independent of host adaptation.

The paper identifies plankton-infecting herpesvirus relatives in marine environments, revealing a new viral phylum with evolutionary links to both herpesviruses and giant viruses.

The paper shows that adding a specific Bacteroides strain early in life reduces colitis risk in genetically susceptible mice with antibiotic-induced gut dysbiosis.

AGNOSTOS-DB is a database that integrates known and unknown coding sequences from genomes and metagenomes to enhance understanding of genes of unknown function.

The paper identifies heterotrophic bacterial diazotrophs as more abundant than cyanobacterial diazotrophs in ocean metagenomes, expanding the known diversity of marine nitrogen fixers.

This study identifies two non-diazotrophic Trichodesmium species through metagenomics, challenging the assumption that all Trichodesmium can fix nitrogen.

This study identifies over 40,000 putative biosynthetic gene clusters in ocean microbes, revealing novel biosynthetic potential and a new candidate genus with diverse metabolic capabilities.

The paper discovers myosin genes in NCLDVs, suggests their role in viral transport, and identifies multiple horizontal transfers of these genes between viruses and eukaryotes.

The paper analyzes plankton genomic distribution across oceans to show how large-scale currents shape biogeography, revealing size-dependent patterns and basin-scale transport effects.

The paper characterizes denitrifier communities in tundra soils and links their composition to N2O flux patterns across different ecosystems.

The paper uses Tara Oceans metagenomic data to reconstruct and analyze eukaryotic genomes, revealing functional convergence among distantly related plankton lineages.

This study links viral community composition to carbon export efficiency in the global ocean, finding that viral marker genes explain 67% of variation in CEE.

The paper presents a framework and workflow to integrate genes of unknown function into genomic analysis, quantifying their diversity and relevance across biomes and providing a resource for studying Cand. Patescibacteria.

The paper identifies actin-related genes in giant viruses, suggesting a possible evolutionary link between viral actins and eukaryotic actin origins.
