Summary: Shortwave infrared (SWIR) hyperspectral imaging was used to classify the freshness of mackerels. Total volatile basic nitrogen (TVB-N) and acid values were analyzed to develop a prediction model by combining them with hyperspectral data. The classification accuracies using raw data from eyes and body data by multiple scatter correction (MSC) pretreatment were 81.68% and 90.14% respectively. The prediction accuracy of TVB-N was 90.76%, and the acid value was 83.76%. These results demonstrate the potential of hyperspectral imaging as a nondestructive method to verify freshness and predict related chemical compounds in mackerels.

Summary: The study of microbial communities on artwork using molecular biology methods has immense potential in identifying potentially damaging species and addressing challenges in restoration and preservation efforts. Different types of artwork, such as paintings on wood, paintings on canvases, and stone sculptures, were found to have differing bacterial communities, with certain oxidase-positive genera potentially responsible for deterioration and fading. This genomics-based approach provides advantages in identifying harmful species that may not be detected using traditional methods and in overcoming challenges in preservation and restoration.

Summary: Microbes are essential for the health, fitness, and metabolism of hosts, and can be found in almost every habitat and organism on Earth. However, we still have limited knowledge about where hosts' microbes reside when they are not on or in the hosts of interest. This study demonstrates that the most species-poor microbiomes are subsets of the most species-rich, and that the microbiomes of plants and animals are nested within those of their environments. Additionally, the distribution of a microbe within a single ecosystem can predict its global distribution, which has implications for understanding global microbial assembly processes.

Summary: This study demonstrates that dietary patterns are more strongly associated with gut microbiome variations than individual dietary features. Prudent-like diets, such as plant-based and flexitarian diets, are associated with higher Healthy Eating Index scores and healthier gut microbiome profiles. Western-like diets, on the other hand, are associated with lower gut microbiome diversity and lower relative abundance of Bifidobacterium.

Summary: Sleep disruption is a common physiological state that can lead to adverse health outcomes. Recent research has found a link between the microbiome and sleep regulation, suggesting that interventions targeting the microbiome may improve sleep quality. This study tested the effects of a prebiotic diet on sleep in rats and found that it increased sleep duration and improved recovery sleep after sleep disruption. The diet also led to changes in the fecal microbiome, with an increase in a specific species that correlated with sleep parameters. These findings suggest that targeting the microbiome may be a unique therapeutic approach for sleep disruption.

Summary: Plants integrate time of day (TOD) information over an entire season to ensure optimal growth, flowering time, and grain fill. A rice expression study in the field revealed that almost all rice genes have a TOD-specific expression over the developmental time course, with thermocycles being a stronger cue than photocycles. The study also identified distinct phasing in the expression of the two grass paralogs of EARLY FLOWERING 3 (ELF3) based on the interaction between thermo- and photo-cycles. This research provides valuable insights into how TOD expression changes under natural conditions and can guide the development of more resilient and prolific crops.

Summary: More than 15 families of aquatic plants use developmental switching strategy to produce dormant propagules called turions in response to environmental stress. However, the molecular details of turion biology are not well-understood due to challenges in isolating high-quality nucleic acids. In this study, a new protocol was developed to isolate high-quality transcripts and perform RNA-seq analysis of mature turions from Spirodela polyrhiza. Comparison of turion transcriptomes with actively growing leaf-like tissue revealed pathways related to stress tolerance, starch and lipid metabolism, and dormancy. The study also identified key genes involved in turion formation and germination, as well as epigenetic changes in turion tissue formation. Similarities between turions and seeds suggest the retooling of key regulators for seed maturation and germination in turion biology.

Summary: In this study, molecular strategies were developed to study duckweed-associated bacteria. A bead-beating protocol was optimized to co-isolate nucleic acids from duckweed and bacteria, and a generic fingerprinting assay was developed to detect bacteria present in duckweed samples. Additionally, strain-specific primers were developed to quantify specific duckweed-bacterium associations and reveal differences in colonization levels between strains from the same genus. Confocal microscopy further supported these PCR results by showing bacterial colonization of the duckweed root-frond interface and root interior.
