Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.Abstract Understanding how measured molecular signals can distinguish the chemistry of life from the chemistry of the nonliving world is a central focus of astrobiology and paleobiology. We train and compare several machine learning (ML) classification models on data from pyrolysis‐gas chromatography‐mass spectrometry (py‐GC‐MS)—a widely available ...

Race in the Metabolic Rift: The Metaphor and Materiality of Whiteness
Antipode, Volume 57, Issue 5, Page 1846-1871, September 2025.Abstract If metabolic rifts are ruptures, chasms, or divisions, what happens inside them? Shifting attention from multi‐scalar socio‐ecological and corporeal metabolisms towards the internal dynamics of rupture, this paper returns to the origins of metabolic thought to see what happens at the bottom of these clefts within nature.

Journal of Metamorphic Geology, Volume 43, Issue 7, Page 681-705, September 2025.ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

, 2013 Breedon Hill forms one of the most prominent features in the landscape of north-west Leicestershire, standing up 50 m above the surrounding ground. That it has been a major landmark throughout recorded history is suggested by its name, which is derived ...

Ecosphere, Volume 16, Issue 8, August 2025.Abstract Little is known about the nitrogen transformation dynamics during the early transition phase from conventional to organic farming. We investigated changes in microbial N‐cycling in agricultural fields transitioning from conventional to organic farming practices by quantifying nitrification/mineralization rates, extracellular enzyme activity ...

Microstructural Evolution of Carrara Marble During Semi‐Brittle Deformation
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.Abstract Fifteen marble samples were subjected to semi‐brittle deformation through triaxial compression experiments, reaching axial strains of about 0.5%, 1.0%, 2.0%, 4.0%, or 7.5% at temperatures of 20°C, 200°C, or 350°C, under a confining pressure of 400 MPa.

Tectonics, Volume 44, Issue 8, August 2025.Abstract Mountain belt architecture and evolution can be represented by frictional Coulomb wedges, a simplification that works well in the shallow deformation conditions of many foreland fold‐thrust belts. However, thin‐skinned fold‐thrust belts often occur in rocks that can deform ductily at low temperature.
