A statistical investigation into relationships between the IIE irons and the ordinary, F and “HH” chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.
Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,

Accelerated Aging, Debilitation, Slow Death, and the Multiple Temporalities of Aging Incarcerated Persons: A Philip K. Dickian Science Fiction Examination

open access: yesNursing Inquiry, Volume 32, Issue 4, October 2025.
ABSTRACT Prisons are debilitating and disorienting spaces. Temporal realities themselves are altered from those of the outside world. This paper builds upon a study of prison staff work with aging incarcerated persons in Canadian federal penitentiaries, wherein the prison environment itself contributes to accelerated aging and slow death ...

Hydrous Components of Dusty Surfaces Inferred From Zhurong In Situ Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The ubiquitous hydration features observed by Zhurong rover provided new insights into Mars aqueous paleoenvironments. However, the impact of the Martian dust was not previously discussed. Here, we conduct a joint analysis of the Multispectral Camera and Short‐Wave Infrared data to constrain the surface composition. The results show that these

The Importance of Pickup H+ Escape at Mars

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The loss of hydrogen ions on Mars to space largely occurs through the interaction of solar wind with planetary atmosphere. However, the relative importance of different ion escape channels is not yet fully understood. In addition, there are still open questions about the proportion of H+ ${\mathrm{H}}^{+}$ escape in relation to total hydrogen ...
