Study on the performance mechanism of alumina-alkali activator synergistic solidified lunar soil simulant

Case Studies in Construction Materials
The utilization of lunar in-situ resources is an important way to realize the construction and operation of Moon scientific research base. The effect of alumina-alkali activator on the mechanical properties of solidified lunar soil simulant was studied ...

Ecoacoustics for context‐rich direct and indirect trophic interaction data and ecological network construction

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding species interactions is critical for ecology and conservation, yet conventional network construction methods often lack spatiotemporal resolution and important contextual information. The growing field of ecoacoustics enables remote sensing across large spatiotemporal scales and the monitoring of otherwise cryptic communities ...

Microspherules Formed by Lightning Strikes

Meteoritics &Planetary Science, EarlyView.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Toxic Entanglements: Asylum and Extraction in the Republic of Nauru

PoLAR: Political and Legal Anthropology Review, Volume 49, Issue 1, May 2026.
ABSTRACT Recent years have seen a dramatic increase in the outsourcing of asylum processing and resettlement from Global North to South. Many of these containment practices retrace the fault lines of more typically thought‐of colonial extractive regimes. This article draws on long‐term ethnographic research conducted in the Republic of Nauru, the world'

Coupled Space Weathering: Nanophase Iron Formation by Micrometeoroid Impact and Solar Wind Sputtering

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the interplay between micrometeoroid impacts and solar wind irradiation is crucial for interpreting lunar surface evolution. Using reactive molecular dynamics simulations and surface binding energy (SBE) analyses, this study investigates the coupled effects of these two dominant space weathering processes on lunar regolith ...

Polarization Changes in Lunar Simulant Soil: The Role of Incident, Reflection, and Off‐Plane Angles

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Observing the polarization of the lunar regolith is essential for obtaining detailed information about the composition and characteristics of lunar soil. Observations conducted via lunar orbiters facilitate polarization measurements over wide areas; however, achieving very high‐resolution imaging requires either a large optical system or a ...

Experimental Investigation of Soil Adsorption Effects on Water Migration in Simulated Lunar Conditions

The Planetary Science Journal
Adsorption is a key mechanism governing water vapor diffusion in lunar regolith. To investigate this process, we conducted experiments under simulated lunar conditions—Knudsen diffusion conditions—using three soil types with varying water vapor ...
