AI Article Synopsis
- Animal venoms are important for research due to their ecological roles and potential applications in pharmacology and biotechnology.
- In Lepidoptera, venoms evolved mainly as defensive mechanisms for larvae and vary in composition and effects, often causing pain or serious health issues in humans and animals.
- Current knowledge on lepidopteran venoms is limited, highlighting the need for further studies to understand their evolution and biological functions.
Article Abstract
Animal venoms are a focus of research due to the hazards they represent and to their relationship to evolution and ecology, pharmacology, biodiscovery, and biotechnology. Venoms have evolved multiple times in Lepidoptera, mostly as defensive adaptations that protect the larval life stages. While venoms are always produced in structures derived from cuticle and setae, they are diverse in their composition and bioactivity, reflecting their multiple evolutionary origins. The most common result of envenomation by lepidopterans is pain and inflammation, but envenomation by some species causes fatal hemorrhagic syndromes or chronic inflammatory conditions in humans or veterinary pathologies such as equine amnionitis and fetal loss. The handful of lepidopteran venom toxins that have been characterized includes coagulotoxins from (Saturniidae) and pain-causing cecropin-like peptides from (Limacodidae). However, our knowledge of lepidopteran venoms remains comparatively poor, with further studies required to yield a clear picture of the evolution, composition, and function of venoms produced by Lepidoptera.

Bats provide important ecosystem services, particularly in agriculture, yet integrating bat management into conservation plans remains challenging. Some landscape features considerably influence bat presence, diversity, and ecosystem service provision. Understanding the relationship between landscape structure, composition, pest suppression, and ecosystem services is crucial.

This study introduces a technique utilizing natural pyrrhotite powder as a nucleating agent in four sequencing batch reactors (SBRs) for the treatment of dye wastewater. Through analysis of various factors including pH, pyrrhotite surface free energy, sludge zeta potential, and shifts in microbial communities, the mechanism by which pyrrhotite facilitates the formation of aerobic granular sludge (AGS) is elucidated. Over 140 days of continuous operation under neutral conditions, natural pyrrhotite rapidly cultivated AGS under neutral conditions.

Using organic oxidation reactions to replace the oxygen evolution reaction is a promising approach for producing high-value organic products and hydrogen. Here, we report a photoelectrochemical benzyl alcohol oxidation system based on an α-FeO photoanode coated with a NiCo-layered double hydroxide (NiCo-LDH) cocatalyst. By adjustment of the relative content of Ni and Co in the NiCo-LDH, the optimized photoanode achieved a benzyl alcohol conversion efficiency of 99.

Integrating conductive supports and modulating electronic structures are widely recognized as effective strategies for improving the catalytic performance of transition metal sulfides. This study demonstrates the simultaneous integration of CoS with two-dimensional TiCT-MXene and the introduction of sulfur vacancies (S) in CoS through a straightforward sintering process followed by plasma treatment, culminating in the formation of the CoS/TiCT composite. Characterization results demonstrate that the TiCT support significantly improves electrical conductivity and promotes the uniform dispersion of CoS nanoparticles.
