Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Effects of Comet Encke's Meteoroid Stream on the Seasonal Variation of Mercury's Ca Exosphere

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mercury's calcium (Ca) exosphere, observed by NASA's MESSENGER mission, exhibits high temperatures (>50000 K) and pronounced seasonal variability, with its source mainly on the dawn side. Enhanced Ca emission near True Anomaly Angle (TAA) ∼25° and ∼150° has been attributed to Comet 2P/Encke meteoroid streams.

Future‐Making From Afar: Digital Twins in Medicine

open access: yesSociology of Health &Illness, Volume 48, Issue 5, June 2026.
ABSTRACT Digital twins in medicine are packaged as inevitable, disruptive technologies that will revolutionise healthcare, yet their integration into clinical practice remains slow. In this article, we extend current research on digital twins by shifting attention to the actors behind the technology and their visions.

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

open access: yesArchaeometry, Volume 68, Issue S3, Page S126-S153, June 2026.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

Common Pressures, Uneven Trajectories: The Variegated Europeanisation of Wage Regulation Institutions

open access: yesBritish Journal of Industrial Relations, Volume 64, Issue 2, Page 286-298, June 2026.
ABSTRACT The debate on whether national industrial relations (IR) are experiencing convergence is a long‐standing one. Recently, scholars argue that we are witnessing a neoliberal convergence of national IR, understood as an increase in employers’ discretion.
