A giant virus with a 4-megabase genome and a vastly expanded repeatome.

The paper describes Sissivirus, a giant virus with a 4-megabase genome and a large repeatome, identifying repeat accumulation as a key driver of its genome expansion.

Identification of Obelisk-like covalently closed circular RNA replicon in hot springs by double-stranded RNA sequencing and expansion of the diversity of the Obelisk superfamily

The paper identifies a new family of Obelisk-like cccRNAs in hot springs using FLDS, expanding the Obelisk superfamily with structurally similar but sequence-divergent proteins.

Transcriptional landscape of the archaeal cell cycle is broadly conserved in eukaryotes

This study analyzes the cell cycle of Saccharolobus islandicus and finds that transcriptional patterns are conserved with eukaryotes, showing phase-specific gene expression for metabolism, protein synthesis, and chromatinization.

"Paraxenoviridae", a putative family of ubiquitous marine bacteriophages with double-stranded RNA genomes

The paper identifies a new family of marine bacteriophages with double-stranded RNA genomes, named Paraxenoviridae, based on genomic and structural analyses.
