The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Feeling‐together, a strategy for honing madness into craft

open access: yesAnthropology and Humanism, Volume 51, Issue 2, December 2026.
Abstract This eclectic piece centers ethnographic practice within networks of feelings that co‐delineate an anthropologist's encounter with imaginative, world‐shaping forces—by carving into peer‐to‐peer repositories for self‐reflexivity. Incidents of madness can thus offer a deliberate resonance and clarity not only to insiders but also to the wider ...

Ablation in meteors [PDF]

open access: yes, 1973
A comparison of theoretical calculations with the results of radar meteor observations shows that the theory of radio meteors satisfactorily represents observational data.

Deer Antler δ18O Records Desalination in Israel's Water Supply

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Stable oxygen isotope ratios (δ¹⁸O) in mammalian tissues are widely used to reconstruct past climates, seasonal patterns, and animal origins. These analyses assume that animals drink local rainwater—an assumption now challenged by large‐scale anthropogenic water management.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Stable Bacterial Cores and Patchy Eukaryotic Communities Shape the Summer Microbiomes of Patagonian Fjord Ecosystems Across Spatial, Functional and Temporal Gradients

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Our study shows that microbial community diversity in Patagonian fjords varies with glacial influence and salinity, with a widespread bacterial core but a patchier eukaryotic core. Distinct co‐occurrence networks and marked short‐term community shifts occur in water‑ versus land‐terminating glacier fjords, underscoring meltwater influence in this ...

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7676-7691, October 2026.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...
