Functional Conservation Amid Extreme Divergence in Freshwater SAR11 Hypervariable Region 2

This study characterizes freshwater SAR11 HVR2 sequences, revealing high intra-population diversity and conserved functional configurations across marine and freshwater lineages.

Characterization of carotenoid-producing Muricauda sp. strains isolated from the reef-building coral Galaxea fascicularis and subtropical seawater

This study characterizes two Muricauda sp. strains isolated from coral and seawater, showing they produce carotenoids that may protect zooxanthellae from environmental stress.

Wistar rats raised in an affectionate environment display lifesaving-like behaviors while distinguishing life from death

The study shows that Wistar rats raised in an affectionate environment display lifesaving-like behaviors, suggesting life valuation is not human-specific.

Nascent MSKIK peptide prevents or releases translation arrest in Escherichia coli

The paper shows that inserting the MSKIK peptide near a start codon enhances protein production in E. coli by preventing or releasing translational arrest.

Male-killing-associated bacteriophage WO identified from comparisons of Wolbachia endosymbionts of Homona magnanima

The paper identifies a male-killing-associated bacteriophage WO in Wolbachia strains of Homona magnanima and proposes a mechanism for male-killing evolution.

Targeted single-cell genomics reveals novel host adaptation strategies of the symbiotic bacteria Endozoicomonas in Acropora tenuis coral

This study uses single-cell genomics to analyze Endozoicomonas bacteria in Acropora tenuis corals, revealing host-adaptive genes that may enhance coral stress tolerance.

Revealing within-species diversity in uncultured human gut bacteria with single-cell long-read sequencing

This study develops a single-cell long-read sequencing workflow to generate complete bacterial genomes from uncultured human gut bacteria, revealing structural diversity and phage insertions within species.

Single-cell metabolite detection and genomics reveals uncultivated talented producer

This study identifies an uncultivated bacterium as a producer of antifungal metabolites using Raman microscopy and single-cell sequencing in a sponge microbiome.

Seroepidemiological survey on pigs and cattle for novel K88 (F4)-like colonization factor detected in human enterotoxigenic Escherichia coli

The paper reports antibodies in pigs and cattle against a novel K88-like colonization factor from human ETEC, suggesting zoonotic potential and the need for One Health approaches.

Prolonged Lifespan, Ameliorated Cognition, and Improved Host Defense of Caenorhabditis elegans by Lactococcus lactis subsp. cremoris

This study shows that Lactococcus lactis subsp. cremoris FC extends C. elegans lifespan, improves cognition, and enhances host defense through mechanisms involving the SKN-1/Nrf2 pathway.

Two-way migration of Lychnis wilfordii caused by the circular landform of Japan-Korea-northeast China-Russian Far East region and its suggestion for conservation in northeast Asia

This study investigates the genetic structure and migration routes of Lychnis wilfordii across northeast Asia, suggesting conservation strategies based on its evolutionary history.

Single-cell genomics of uncultured bacteria reveals dietary fiber responders in the mouse gut microbiota

This study develops a single-cell genomic sequencing technique to identify bacterial responders to dietary fiber in the mouse gut microbiota, revealing metabolic pathways and functional lineages involved in fiber fermentation.

Serpentine mountain uplift in northern Japan triggered the divergence of a narrow endemic from a widespread (sub)arctic Asia-Alaska species complex of Lagotis (Plantaginaceae)

The paper investigates the divergence of two narrow endemic Lagotis species in northern Japan from a widespread (sub)arctic Asia-Alaska species complex, linking it to mountain uplift and ecological factors.

Merger of Betula tatewakiana (Betulaceae) from northern Japan to northeast Asian B. ovalifolia based on ploidy level

The paper resolves a taxonomic dispute by showing Betula tatewakiana is tetraploid and morphologically identical to B. ovalifolia, leading to their merger.
