Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5701-5711, November 2026.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...

Contrasting influences of ectomycorrhizal fungi on decomposition depending on soil fertility

New Phytologist, Volume 252, Issue 3, Page 1028-1034, November 2026.
Ecosystem types along a gradient of increasing nutritional and climatic constraints with an overall transition from carbon (C)to nitrogen (N) limitation on decomposition. Summary Despite their dominance in many terrestrial ecosystems, the impact of ectomycorrhizal fungi on organic matter decomposition is notably variable across different ecological ...

Meter‐Scale Roughness of the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Small‐scale surface roughness is a key indicator of local geological processes, yet it has not previously been mapped globally on the Moon. We present global meter‐scale surface roughness maps generated from the Lunar Orbiter Laser Altimeter pulses, which record information about surface undulations within the instrument's ∼5 m individual ...

Measurements of the Size and Physical Properties of Marine Particles Using Atomic Force Microscopy: Implications for Marine Biogeochemical Cycles

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Particle size and physical properties such as stiffness and adhesiveness affect sinking velocity and flux in the ocean, yet conventional two‐dimensional measurements lack accuracy and mechanical information. In this study, we applied atomic force microscopy (AFM) to quantify three‐dimensional size and physical properties of marine particles ...
