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

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 ...
