Sustainable and Programmable Hydrogels for Bone Regeneration: A Perspective on Green Synthesis and Precision Fabrication

open access: yesSusMat, EarlyView.
The clinical translation of natural hydrogels is often hindered by a fundamental conflict. Green synthesis prioritizes biosafety through mild and non‐toxic conditions, whereas precision manufacturing demands mechanical robustness and structural fidelity.

Advancing Biomass Valorization via Electrocatalytic Oxidation: Design Principles, Emerging Challenges, and Future Perspectives

open access: yesSusMat, EarlyView.
This review categorizes substrates for electrocatalytic biomass valorization by carbon chain length into C2–C3 alcohols, C5–C7 cyclic compounds, and Cn biopolymers. It identifies four universal catalyst design principles: optimizing intermediate adsorption, engineering synergistic multi‐type active sites, accelerating active‐site formation, and ...

Saline versus alkaline stresses in paddy soils drive divergent microbial nutrient limitations despite shared carbon constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil salinization and alkalization often suppress microbial functional activity, triggering negative feedback loops in microbial metabolism, degrading nutrients and agricultural productivity.

Carbon flow to generalist predators shifts between plant‐ and fungal‐derived resources in highly seasonal ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
Using amino acid isotope fingerprinting, Sagi et al. show how Arctic wolf spiders shift between plant‐ and microbe‐based energy sources with changes in body size and plant productivity. This reveals how environmental conditions and consumer traits jointly shape carbon flow and link green and brown food webs in rapidly changing ecosystems.

Microbial mineralization rates of chitin in a freshwater habitat, and purification of the chitinase complex from Pseudomonas sp.

open access: yes, 1983
Microbial action on particulate chitin was analyzed in an eastcentral Indiana borrow pit lake. Experiments were conducted to determine the effects of water depth, particle size, mesh size of nylon bag containing chitin, and season on the decomposition ...

Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

open access: yesIntegrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

open access: yesIntegrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

The fight of innate immunity and abnormal cannabinoids against Candida infection

open access: yesBritish Journal of Pharmacology, EarlyView.
Candida species represent the most clinically significant fungal pathogens in humans, with invasive candidiasis carrying a mortality of 30%–40% in critically ill patients despite modern antifungal therapy. The innate immune system – through the coordinated and specific activities of neutrophils, macrophages, NK cells, mast cells and eosinophils ...
