Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Hyperpolarized MRI in Oncology—A Review of Clinical Studies and Evaluation of Preclinical Liver Studies

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Hyperpolarized MRI is a promising clinical imaging modality in oncology, offering at least nine imaging contrasts obtainable with hyperpolarized [1‐13C]pyruvate as the injected agent, depending on the tissue and condition under investigation. Preclinical studies suggest that hyperpolarized MRI is warranted for detecting hepatocellular carcinoma within ...

CO2 and N2O Emissions From Vehicles in Seoul Megacity, South Korea: Insights From Mixing Ratio and Stable Isotope Ratios

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Vehicular traffic is a major source of anthropogenic greenhouse gases in megacities; however, real‐world constraints on vehicle‐derived N2O emissions and their isotopic characteristics remain limited. Methods Air samples were collected from three tunnels and urban background sites (a university campus and mountain) in Seoul, South ...

Organic‐matter sources and stability in kettle‐hole sediments: A combined thermogravimetric and isotopic approach

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Kettle‐holes are small but biogeochemically active landscape elements that integrate terrestrial inputs and influence carbon and nitrogen cycling. However, the stability and sources of organic matter (OM) in kettle‐hole sediments remain poorly understood.

Inherent α‐Helix Around Tyrosine 183 in the Intrinsically Disordered Tail of the Multi‐Site Docking Platform Gab1

open access: yesBiopolymers, Volume 117, Issue 5, September 2026.
The two phosphorylation sites within the Gab1 fragment 142‐203 exhibit distinct structural characteristics. Tyr162 is in a disordered region, Y183 in a helical segment. ABSTRACT The biological function of intrinsically disordered proteins is frequently coupled to short linear motifs, which serve as protein binding sites.

CSAKD: Determining Absolute Ligand Affinities From 19F NMR Chemical Shift Anisotropy

open access: yesAngewandte Chemie, Volume 138, Issue 33, 10 August 2026.
Affinity determination is crucial in drug discovery, yet remains difficult for weakly binding fragments. We introduce chemical shift anisotropy KD$K_{\text{D}}$ (CSAKD) by 19F$^{19}{\rm F}$ NMR relaxation experiments, a titration‐free method that requires no isotopic labeling.

Recent Advances in Metal‐Organic Framework Photo‐Electrocatalysts for the Synthesis of Ammonia

open access: yesCarbon Neutralization, Volume 5, Issue 5, September 2026.
This diagram illustrates the role of Metal‐Organic Frameworks (MOFs) in the photocatalytic and electrocatalytic synthesis of ammonia, highlighting their potential as efficient catalysts for sustainable nitrogen fixation under light irradiation and electrode excitation.

Decadal Bowhead Whale Baleen Stable Isotope and Hormone Chronologies (1985–2010) Provide Insight Into Arctic Ecosystem Change

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

Transition Metal Chalcogenides: Perspectives on Their Applications for Nitrate Reduction

open access: yesChemistryOpen, Volume 15, Issue 9, September 2026.
This review paper reports the syntheses, properties, and applications of TMCs for electrochemical reduction of nitrate to ammonia. Various studies revealed that the conversion of nitrate to ammonia is principally the electrocatalytic hydrogenation of nitrate and the rate and yield of ammonia is competitively challenged by hydrogen evolution reaction ...
