Summary: In this study, a multifunctional hydrogel bio-glue was developed using polyglutamic acid (PGA), tyramine hydrochloride (TYR), and tannic acid (TA) as precursors and DMTMM as condensation agent. This bio-glue showed strong adhesion to various tissues and wet materials, and also exhibited anti-oxidation and hemostasis functions. It demonstrated excellent performance in wound, liver, and cartilage repair, indicating its potential for clinical application. This study opens up a new avenue for the development of multifunctional hydrogel bio-adhesives.

Summary: Viral quasispecies are distinct but closely related mutants formed by recombination, mutations, competition, and selection pressure. Their origin is attributed to the error-prone replication by polymerase and mutants of RNA replicators. The impact of quasispecies for major human pathogens is reviewed, and the rapid changes in geographical landscapes favor the origin and selection of mutants, posing a significant risk to public health.

Summary: This study comprehensively characterized coral-associated microbial aggregates (CAMAs) in Stylophora pistillata and found multiple coexisting Endozoicomonas phylotypes. These CAMAs enriched with phosphorus have different elemental compositions from coral tissues and symbiotic Symbiodiniaceae, highlighting their role in sequestering and cycling phosphate. The consensus metagenome-assembled genomes of dominant Endozoicomonas phylotypes confirmed their metabolic potential and genomic signatures related to polyphosphate accumulation and host association.

Summary: Tumour-Associated Macrophages (TAMs) are a key component of the tumour microenvironment, with complex roles in cancer immunity. TAMs can exhibit both pro-tumour and anti-cancer activities. Advanced single-cell technology has revealed novel dedifferentiation phenomena of TAMs. Additionally, TAMs show potential in cancer immunotherapy.

Summary: Three new p-terphenyl derivatives and three new indole-diterpene alkaloids, along with known analogues, were isolated from the fungi associated with the gorgonian in the South China Sea. The structures and absolute configurations of the new compounds were elucidated through spectroscopic analysis and calculations. These compounds modulated neuronal activity and a preliminary structure-activity relationship was discussed.

Summary: This study investigated the antagonistic interactions among coral-associated bacteria at different temperatures, revealing an increase in antagonism breadth but decrease in antagonism intensity at 32 degrees C. The competition networks were more influenced by antagonist strains than sensitive strains, with elevated temperature leading to a more complex antagonistic network. Antagonism probability was found to correlate with phylogenetic distance rather than phenotypic distance, indicating a trade-off between antagonism and resource exploitation under higher temperatures.

Summary: By using AGO-crosslinking immunoprecipitation (AGO-CLIP) for AGO1 and AGO2 in Aedes aegypti mosquitoes, researchers identified a comprehensive RNAi network map with 230 small RNAs and 5,447 small RNA targets. The study also revealed unexpected AGO2 target preferences and demonstrated that mosquito AGO2 repressed imperfect targets, expanding our understanding of small RNA networks and antiviral RNAi research.

Summary: This essay explores the nature of viruses from biological, historical, philosophical, and anthropological perspectives, emphasizing their interconnectedness with human society and history. It argues that the virus blurs distinctions between natural and human-made, biological and social, prompting a reflection on the human condition in the context of the pandemic, essentially creating an anthropology of the virus.

Summary: This study evaluated cortisol content in the scales of tropical tuna for the first time, finding that cortisol concentration was not geographically patterned, independent of fish size, and significantly higher in skipjack tuna compared to yellowfin tuna. Future research is needed to confirm species differences in cortisol concentration and explore the links between chronic stress and behavior in these species.

Summary: This study investigated the taxonomic diversity of viruses in different organs of skipjack and yellowfin tuna, revealing significant differences in virome composition between organs but not dependent on tuna species or sex. The tuna virome was mainly dominated by eukaryotic viruses in digestive organs, while bacteriophages were predominant in the mucus. A 'core virome' composed mainly of Caudovirales, Microviridae, and Circoviridae was found to be shared by all organs, indicating a mosaic of viral niches in tuna awaiting further elucidation of their establishment, role, and circulation.

Summary: This study utilized metabarcoding to investigate the gut bacteriome in three tuna species, finding significant differences in the microbial communities of yellowfin and bigeye tuna as they grow, while the skipjack tuna's bacteriome remained relatively constant. The results suggest that the gut bacteriome of marine fish may not always undergo structural modifications during growth, especially in species with consistent feeding behaviors throughout their lifetime.

Summary: The study found that the coral-macroalgal shift did not impact the diversity and richness of fish gut bacteriomes, but significantly influenced the composition, especially in herbivorous fishes. On macroalgal dominated reefs, there was a significant increase in fermentative bacteria in fish gut microbiota, along with changes in metabolisms related to carbohydrates, DNA replication, and nitrogen metabolism, which could potentially affect ecosystem functioning.

Summary: Although tunas represent a significant part of the global fish economy and a major nutritional resource worldwide, their microbiome remains poorly documented. This study analyzed the taxonomic composition of bacterial communities in the gut, skin, and liver of two widely consumed tuna species. The results showed that the composition of the tuna microbiome was independent of fish sex, but varied according to tuna species and sampling site. The study also discovered a unique and diverse bacterial assemblage in the tuna liver, including potential histamine-producing bacteria.

Summary: We report on the genomic traits associated with the life history of prokaryotes and discuss conflicting findings regarding trait correlations and tradeoffs. By examining variations in 11 genomic traits from approximately 18,000 sequenced genomes, we found that resistance traits of prokaryotes are decoupled from resilience traits and traits associated with resource availability. However, the relationship between resistance and resilience traits differs based on genome size and habitat, suggesting habitat-dependent tradeoffs. Our findings challenge the globally consistent assignment of prokaryotic genomic traits and propose the use of taxonomic marker genes to extrapolate genomic traits. This allows for the empirical evaluation of these traits in prokaryotic communities from different habitats using the resistance-resilience framework.

Summary: The presence of marine snails poses a potential threat to the survival of Acropora coral species in Phu Quoc Islands, leading to changes in coral reef health and bacterial diversity. The composition of bacterial communities associated with Acropora formosa and Acropora millepora was studied using Illumina sequencing technology. The analysis revealed the presence of diverse bacterial genera, with significant differences in relative abundances between grazed and healthy coral samples.
