The impact of physiological oxidants on triggering amyloid formation of the cell cycle regulator protein p16INK4A

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The tumor suppressor protein p16INK4a plays a key role in cell cycle control and is frequently inactivated in human cancers. We previously discovered that oxidation of its single cysteine residue induces a structural transition from the functional monomeric form into inactive amyloid fibrils.

Synergetic Ruthenium Clusters and Ligand Motifs in Insoluble Polyoxometalates for Efficient Urea Electrosynthesis

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.

Nanomaterials‐Decorated Biomass‐Derived Carbon for Overall Water Splitting: Interfacial Engineering, Mechanistic Insights, and Device Translation

The Chemical Record, Volume 26, Issue 8, August 2026.
Biomass‐derived carbon provides a sustainable, porous, and conductive scaffold that stabilizes nanomaterials for bifunctional hydrogen evolution reaction/oxygen evolution reaction catalysis. This review summarizes design strategies (defects, heteroatom doping, heterostructures, single atoms), mechanistic/density functional theory insights, degradation ...

Agricultural Emissions of Reactive Nitrogen Gases From Constrained Simulations Using the Community Land Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Reactive nitrogen (Nr) gases (NH3, N2O, and NO) emitted from agricultural fields constitute a substantial portion of the Nr flux from land to the atmosphere. Here, we coupled the Flows of Agricultural Nitrogen (FANv3) with a modified version of the Community Land Model (CLM5.1) to produce a model (CLM‐FANv3) that simulates the emissions of NH3,

Transient Ecological Niches for Diazotrophs in Upwelling Bays

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18
