Summary: The study found that the novel insecticide chlorantraniliprole can reduce the emergence rate of dragonfly nymphs into adults, especially for S. infuscatum, but not significantly for S. frequens. This difference could be attributed to differing sensitivity to chlorantraniliprole, varying nymphal stage lengths, or the impact of bottom-up controls on prey organisms sensitive to the insecticide.

Summary: Anthropic activities can affect aquatic communities and reproductive behavior of species. Functional characteristics play a vital role in species occurrence and respond differently to human impacts in the Eastern Amazon. Altered environments favor heliothermic and exophytic species, while preserved environments support species with endophytic and epiphytic oviposition and ectothermic thermoregulation. Morphologically, altered environments favor medium to large individuals, whereas preserved environments may favor smaller and/or specialized species.

Summary: Based on mu-HPLC/MS/MS analysis, the predominant anthocyanins in red raspberry were identified as Cyanidin-3-O-sophoroside, cyanidin-3-O-rutinoside, and cyanidin-3-O-glucoside. In contrast, delphinidin-3-O-beta-D-glucoside, cyanidin-3-O-glucoside, malvidin-beta-D-glucopyranoside, and peonidin-3 beta-D-glucoside were found to be the main anthocyanins in grape. The stability of anthocyanins in raspberry was lower than those in grape under natural conditions or during fermentation, with higher loss rates after UV irradiation, heat treatment, and oxygen exposure.

Summary: In this work, a visual and easy-to-implement representation approach of red wine color is introduced. The feature color of wine under standard conditions is reproduced as a circular spot, which is further decomposed into chromatic and light-dark components. The wine color characterization using this method shows that it effectively represents the color characteristics and provides intuitive visual perception, making it more reliable and convenient than the photographic method. The applications for monitoring color evolution and age discrimination of red wines suggest that this visual method is effective for color management and control during fermentation and aging of wine.

Summary: This study found that the color red influences the categorization of human bodies by sex. When red is used as the body color, it biases perception towards feminine bodies, while when used as the background color, it biases perception towards masculine bodies. These findings highlight the impact of color on sex recognition.

Summary: The yellow-winged darter, a flagship species associated with high mountain areas, will be negatively affected by climate change. This study predicts the global potential distributions for this species under different time periods and socioeconomic pathways. Results suggest that under the worst climate scenario, the species' distribution may be reduced by almost half, posing a risk of shifting from vulnerable to endangered. Connectivity analysis shows that the importance of core habitats will increase, potentially leading to isolation of some populations.

Summary: The study introduces a pattern-recognition-based protein sensing approach using a simple one-component array composed of charged poly-L-lysine modified with environment-responsive dansyl fluorophores for the identification of proteases. By dissolving the array of PLL-Dnc in buffer solutions with different pH values, fluorescent patterns unique to each protease are produced, enabling the identification of eight proteases through multivariate analysis. The method allows discrimination of mixtures of trypsin and alpha(1)-antitrypsin (ATT) with different compositions, and is expected to have broad applications in screening protein-protein complexes formation and disease-associated protease detection.

Summary: The order Odonata, consisting of dragonflies and damselflies, is one of the most ancestral groups of winged insects with drastic morphological changes during metamorphosis. Through a comprehensive survey of 158 larvae representing 49 species and 14 families, two visually recognizable morphogenetic events were consistently identified in the final larval instar, categorizing it into three stages. The duration of these stages varied across different Odonata species, with the second and third stages showing relatively small variations, reflecting a steady and irreversible metamorphosis process. Other characteristic morphological changes were also described during larval development, but were only observed in specific Odonata species and lineages.

Summary: The study introduces a novel strategy of using chemical additives to modulate probe/analyte interactions for constructing pattern-recognition-based sensing systems. The enhanced fluorescence of dansyl-modified cationic poly-L-lysine upon binding to proteins generates response patterns that accurately identify structurally similar albumin homologues and mammalian cells through multivariate analysis. This inexpensive and accessible strategy offers new opportunities for bioanalytes detection.

Summary: The order Odonata is a group of ancient winged insects that use visual cues to recognize each other, with the molecular mechanisms of pigmentation, particularly light-blue coloration, playing a crucial role. Results from histology and pigment analysis show that specific pigments are essential for the light-blue coloration, and further gene-functional analysis is needed for future studies.

Summary: This study demonstrates the roles of DNA components in liquid-liquid phase separation of proteins and DNAs, including electrostatic interactions between phosphate groups and deoxyribose, as well as interactions involving nucleobases and deoxyriboses. These interactions promote the generation of spherical liquid droplets and modulate the density of DNA within the droplets under low-salt conditions. Additionally, non-spherical assemblies with both mobile and immobile fractions were observed at higher concentrations of a polycationic peptide, linker histone H1, for all DNA oligomers.

Summary: This study investigates the remodeling mechanism of symbiotic organs and its impact on microbial symbionts during insect metamorphosis. By manipulating the metamorphosis process in stinkbugs, the researchers discovered that the symbiotic organ transformed from nymph type to adult type under the control of the MEKRE93 pathway. The remodeling of the symbiotic organ not only affects the retention function of symbionts but also extends its role in food digestion. Additionally, the symbiotic bacteria in the adult-type symbiotic organ were found to upregulate genes associated with the production of sulfur-containing amino acids, indicating their specific function in host reproduction.
