Global Structure of the Cislunar Magnetotail and Its Evolution During Substorms

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract So far, the structure and dynamics of the terrestrial magnetotail have largely been investigated within 31RE $31{R}_{E}$ (RE ${R}_{E}$ is the Earth's radius) because of the lack of in‐situ observations beyond that distance, as well as limitations of earlier empirical models.

Cooling History and Evolution Dynamics of Green Glass Beads During Lunar Fire‐Fountain Eruptions: Insights From Na, K and Cu Distributions

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Volcanic glass beads on the Moon have traditionally been thought to only record volatile loss during pyroclastic eruptions. However, recent discoveries have shown that lunar orange glass beads, representing primitive high‐Ti basalts, experienced both outgassing and in‐gassing of volatile elements such as Na, K, Cu, and S.

‘I LEARNED TO MAKE A LOT MORE SPACE IN MYSELF FOR OTHER PEOPLE’: Examining the Negotiation of Hegemonic and Alternative Values in the Urban Commons

International Journal of Urban and Regional Research, Volume 49, Issue 4, Page 912-928, July 2025.
Abstract In this article, we examine the urban commons through the concept of subjectivity. We attend to the ways in which alternative and hegemonic values are negotiated among different commoners and within individual commoners. Which challenges do commoners face as they pursue alternative values within the context of capitalist urbanization?

Energy Storage and Environmental Justice: A Critical Examination of a Proposed Pumped Hydropower Facility in Goldendale, Washington

Antipode, Volume 57, Issue 4, Page 1236-1258, July 2025.
Abstract Renewable energy sources such as solar and wind produce electricity intermittently, creating challenges in balancing electricity supply and demand for increasingly renewable‐dominated grids. This is driving efforts to increase energy storage infrastructure, such as pumped hydroelectric power storage (pumped storage).
