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 ...

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 ...

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 ...

Hydrothermal Contributions to Elevated Dissolved Organic Carbon Concentrations and Cycling Along the Mid‐Atlantic Ridge

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Hydrothermal systems along the Mid‐Atlantic Ridge (MAR) are spatially variable sources of dissolved organic carbon (DOC) to the deep ocean, with implications for carbon cycling and trace‐metal transport. We present DOC measurements from four research cruises focusing on major vent fields at Menez Gwen, Rainbow, Lost City, Broken Spur and TAG ...

Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set records direct sampling of total atmospheric deposition from March 2015 to ...

An Integrative Approach Toward Bio‐Inspired Sequestration of Rare Earth Elements

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
The binding behavior of EF‐hand 4 of calmodulin toward different lanthanide ions was studied using a combination of spectroscopic and computational methods. A resin‐immobilized peptide demonstrated its potential as a selective and sustainable filter material for lanthanide separation.Lanthanides (Ln) are essential for renewable energy technologies, yet
