Rational Design of Ni3+‐Rich Nickel Nitride Enables Paired Electrooxidation of Sterol and Hydrogen Evolution in a Flow Electrolyzer

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
The rational design of Ni3+‐rich active sites on nickel nitride nanosheets via Pd‐induced electronic modulation, which was employed in the electrooxidation of sterol coupled with H2 production in a large flow electrolyzer. This work offers a novel strategy for the design and synthesis of highly efficient electrocatalysts and electrolyzers toward the ...

Evaluation of Acephate Metabolites Generated by Zebrafish (Danio rerio) Using LC–HRMS and Metabolomics Approach

open access: yesJournal of Applied Toxicology, Volume 46, Issue 5, Page 1679-1686, May 2026.
ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in

A Distinct Tryptophan Metabolic Phenotype Marks Severe Fatigue in Quiescent Crohn's Disease

open access: yesJCC Plus, Volume 1, Issue 3, May 2026.
ABSTRACT Background Fatigue is a common and debilitating symptom in inflammatory bowel disease (IBD), but its underlying mechanisms remain unclear. Altered tryptophan metabolism may contribute to fatigue. Tryptophan is metabolized through the kynurenine, serotonin, and indole pathway, involving host and microbial processes. We aimed to explore the link

Photoenzymatic Hydroalkylation Enables Streamlined Access to Aryl Glutarimide Precursors

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We report a photoenzymatic hydroalkylation that enables streamlined, stereocontrolled access to aryl glutarimide precursors relevant to targeted protein degradation. Engineered flavin‐dependent “ene”‐reductases provide broad scope and high enantioselectivity through a distinct electron transfer–enantioselective proton transfer pathway.

Reliable Estimation of Wavenumbers for Calcite Peaks

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 5, Page 821-827, May 2026.
The wavenumbers of the calcite peaks were accurately estimated using a combination of a He–Ne laser and Ne emission lines. The values following the ± symbol represent the expanded uncertainties, corresponding to an approximate 95% confidence interval. ABSTRACT The Raman‐shift wavenumber ( ∆ν~), which is calculated as the difference between the absolute

Metal‐Free, Chemoselective Reduction of Aromatic Nitro Compounds in Water at Room Temperature

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
A metal‐free, rapid, and chemoselective nitro reduction of aromatic compounds is developed using tetrahydroxydiboron as reducing agent and 4,4′‐bipyridine as organocatalyst. This green method provides an efficient entry to aromatic amines with high functional group tolerance in excellent yields under mild conditions using water as solvent. A metal‐free,

A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

open access: yesEnvironmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Novel Ligands for the Orphan Receptor GPR151 Modulate Morphine Action

open access: yesGenes to Cells, Volume 31, Issue 3, May 2026.
The new GPR151 ligands altered the analgesic effects of morphine. ABSTRACT GPR151 is an orphan G‐protein‐coupled receptor expressed on specific neurons. Its expression has been reported to be upregulated in the dorsal root ganglia in mouse nerve injury models, suggesting a role in pain transmission.
