A Nutrient‐Based Biostimulant Application Partially Alleviates Negative Effects of Glyphosate Drift on Wheat

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT The extensive use of glyphosate for weed control in‐crop poses significant risks to non‐target crops, such as wheat, due to spray drift. Biostimulants are widely used to improve nutrient uptake, stimulate root growth, and enhance tolerance to abiotic stress. These growth effects of biostimulants may aid in alleviating glyphosate‐induced damage

Occurrence of Food Chemical Contaminants in Entomophagy: Implications for Food Safety and Future Risk Assessment—A Scoping Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Entomophagy is increasingly recognized as a sustainable alternative to conventional protein sources due to its low environmental impact. However, ensuring its safety requires careful evaluation of chemical contaminants of food safety concern.

Assessment and Correction of Non‐Linearity Effects for In Situ Rb‐Sr Geochronology Applied to High 87Rb/86Sr Mica

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 601-624, September 2026.
Key Points Measurement of 86Sr at count rates < 1500 cps can result in statistical bias. Non‐linear signals in analogue detection mode (e.g., Rb) present a challenge for accurately dating high 87Rb/86Sr mica (> 1000). Accounting for these considerations, high 87Rb/86Sr mica are dated here with accuracies of ∼ 1%.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 625-647, September 2026.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Metal–Phenolic Coatings Enable Universal Design of Spherical Nucleic Acids

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
A general and straightforward strategy for constructing spherical nucleic acids (SNAs) using metal–phenolic (MP) coatings has been developed. The resulting MP‐SNAs exhibit many of the hallmark SNA properties, including enhanced cellular uptake, and serve as versatile building blocks for the programmable assembly of a diverse library of nanoparticles ...

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ56Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Guiana, reveal the response of Fe hosted in laterite to past changes in ...
