Power Leveraging: The Everyday Expansion of the Grassroots State in Urban China
ABSTRACT China has witnessed a notable expansion of state power during and after the pandemic, particularly at the grassroots level. How has this occurred? The Shequ, a grassroots state agent, has played a central role, taking on extensive administrative responsibilities aimed at enhancing social management, often at the expense of rule‐of‐law ...

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 ...

Substorm Effects on Chorus Emissions Modulated by ULF Waves
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

Impact Craters Reveal a Deeper Rock‐Poor Regolith in the Lunar Highlands
Abstract The only measurements of the highlands regolith occurred at the Apollo 14 and 16 landing sites, finding 10–15 m thick regolith; however, we show that the Apollo landing sites are anomalous due to their proximity to rare, highlands rocky craters and because they landed atop basin ejecta. Through observations of rocky crater populations, we show

Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.
