Abstract Modeling processes within Earth's and other planetary bodies' mantle requires constraints from phase equilibrium to infer how changes in phase abundance and composition affect physical properties and geochemical processes. When applying such thermodynamic models on a planetary scale, performance becomes especially crucial.

Electron Regulation of Proton Cyclotron Waves at Mars
Abstract Proton cyclotron waves (PCWs), generated by the solar wind ionization and subsequent pickup of exospheric hydrogen, offer independent constraints on water loss from Mars. However, translating wave observations into quantitative escape rates has been hindered by an incomplete understanding of wave evolution, particularly the role of electron ...

Abstract Perchlorate (ClO4−) in polar ice preserves past chlorine oxidation chemistry; however, multi‐centennial Antarctic ClO4− records and the mechanisms controlling their variability remain poorly constrained. Here, we present the first 400‐year (1616−2016) ClO4− record from an Antarctic ice core, revealing two regimes separated around 1980.

The articles in this issue of “Aisthesis” collectively highlight the significance of aesthetic habits in shaping our artistic, cultural, and social landscapes. The theoretical research presented invites readers not only to become aware of the role of habits in aesthetic life and artistic experience but also to engage actively in acquiring good habits ...

Abstract There is growing interest in nature‐based hybrid flood risk mitigation, in which wetland ecosystems, such as tidal marshes, are an integral part. Tidal marshes can attenuate wave loading on defense structures, reduce breach depth in case of defense structure failure, attenuate storm surges, reduce shoreline erosion, and grow vertically with ...

We characterized the vertical profiles of archaeal community composition, function, co‐occurrence networks, and assembly mechanisms in mangrove sediments across six depth intervals. Deep sediments hosted higher archaeal diversity, with distinct taxonomic and functional shifts, and more stable co‐occurrence networks compared to surface layers ...
