Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)
Terra Nova, EarlyView.ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis
Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver

Review of Education, Volume 14, Issue 1, April 2026.Abstract This study presents a systematic, reproductive and comparative review of research on students' interest, motivation and attitude (I/M/A) towards science and technology (S&T) at K‐12 levels, covering the period 2013–2024. As a follow‐up to a previous systematic review (2000–2012), it describes and synthesizes findings from 170 peer‐reviewed ...

From Hurricane Irma to the Grindavík eruptions: volatility premiums in disaster governance
Disasters, Volume 50, Issue 2, April 2026.Abstract Environmental volatility can inflate property values even as it destroys them. To show how, this article pairs a postcolonial micro‐state in the Caribbean (Sint Maarten after Hurricane Irma) with a Nordic welfare town (Grindavík in Iceland following volcanic eruptions) because they occupy the opposite ends of the governance capacity spectrum ...

Rapid Communications in Mass Spectrometry, Volume 40, Issue 5, 15 March 2026.ABSTRACT Rationale Laser ablation mass spectrometry provides fast and direct chemical information of solids with high spatial resolution without the need for complex sample preparation. It has been shown that reducing the laser pulse length below picoseconds improves the quantification of chemical composition measurements of solids. This study compares

Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract This study compares the vertical tilt and potential vorticity (PV) $(PV)$ structure of average and extreme extra‐tropical cyclones (ETCs) in the Northern Hemisphere during the cold season (October–March) in ERA5 reanalysis. Vertical tilt is quantified using a novel two‐component (directional and lateral, aligned with and across cyclone motion)
