Prey DNA Detection in Lycosid Spiders Is Primarily Influenced by Time Since Feeding and Primer Choice

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 789-794, July 2026.
Gut content analysis using DNA metabarcoding has improved understanding of predator–prey interactions involving spiders. We tested how starvation before feeding, time since feeding, spider size, and the presence of egg sacs or spiderlings affect prey DNA detection in Lycosidae.

Theoretical and Practical Implications Derived From the Formulation of the Theory of Critical Distances

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2610-2618, July 2026.
ABSTRACT The Theory of Critical Distances comprises several methodologies that allow fracture, fatigue, and stress corrosion cracking phenomena to be analyzed. Such methodologies are usually referred to as the Point Method (PM), the Line Method (LM), the Area Method (AM), and the Volume Method (VM).

Enhanced Biomethane Recovery From Source‐Separated Cow Urine via Co‐Digestion With Waste Paper

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
This study outlines the experimental process where cow urine, collected from a dairy barn equipped with a source‐separating manure system, and waste paper are loaded into bioreactors (CU0–CU50) at varying ratios to analyze the biogas yield. The analytical results highlight that this collection system significantly enhances biogas and biomethane ...

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

open access: yesNew Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Low‐Temperature Initiation Enhances HCN and NH3 Formation From Methane and NO Over Pt/Al2O3

open access: yesChemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Hydrogen cyanide (HCN) was formed from CH4 and NO over Pt/Al2O3 at low temperatures. Increasing NO concentration and optimizing reaction‐start conditions significantly enhanced HCN yield. In situ FTIR and DXAFS measurements revealed that dynamically balancing Pt‑CO and Pt‑CN surface species, particularly their desorption under temperature‑swing ...
