A Machine Learning‐Based Geothermal Gradient Framework for Constraining Lithospheric Biomass

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Earth's deep subsurface hosts a large microbial biosphere, but the magnitude of lithospheric biomass remains poorly constrained due to sparse observations and uncertain thermal limits. Here, we present a physically constrained global assessment of the continental and oceanic lithospheric biomass shallower than the 122°C isotherm.

Contrasting Palaeogeographic Histories but Similar Microevolutionary Responses in Low‐Dispersal Island Grasshoppers From Two Mediterranean Archipelagos

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Island archipelagos serve as natural laboratories for understanding how geological history, climate change and dispersal limitation interact to shape diversification. Here, we examine how these forces influence patterns of genomic divergence, demographic dynamics and phenotypic variation in island‐endemic taxa, with a particular focus on ...

Groups with a finite Busemann boundary are virtually cyclic

Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract This note is a continuation of the study of the relationship between the geometry of Cayley graphs and the size of its metric‐functional boundary. We show that if there exists a Cayley graph with finitely many Busemann points, then the underlying group is virtually cyclic.

Mizohata–Takeuchi inequalities for orthonormal systems

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We establish some weighted L2$L^2$ inequalities for Fourier extension operators in the setting of orthonormal systems. In the process, we develop a direct approach to such inequalities based on generalized Wigner distributions, complementing the Schatten space approach that is prevalent in the wider context of estimates for such orthonormal ...

An EZ${\mathcal {E}\mathcal {Z}}$‐structure for the mapping class group

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We construct a boundary for the mapping class group Mod(S)${\rm Mod}(S)$ of a surface S$S$ of finite type. The action of Mod(S)${\rm Mod}(S)$ on this boundary is minimal, strongly proximal and topologically free. The boundary is the boundary of an EZ${\mathcal {E}\mathcal {Z}}$‐structure for Mod(S)${\rm Mod}(S)$.
