Freshwater Conservation Priority Areas Are Threatened by Global Mining Activities

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Meeting global mineral demands, including those for decarbonization, risks amplifying threats to freshwater biodiversity. This study presents the first global mapping of conflicts between mining and freshwater conservation, revealing that mining may contaminate up to 1.8 million km of rivers, with over 18% within conservation priority areas.

Quasi‐Fuchsian flows and the coupled vortex equations

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.
Abstract We provide an alternative construction of the quasi‐Fuchsian flows introduced by Ghys. Our approach is based on the coupled vortex equations that allows to see these flows as thermostats on the unit tangent bundle of the Blaschke metric, uniquely determined by a conformal class and a holomorphic quadratic differential.

Connected components of the space of flags of SO0(p,q)$\operatorname{SO}_0(p,q)$ transverse to a fixed pair and restrictions on Anosov subgroups

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract We count and give a parametrization of connected components in the space of flags transverse to a given transverse pair in every flag varieties of SO0(p,q)$\operatorname{SO}_0(p,q)$. We compute the effect the involution of the unipotent radical has on those components and, using methods of Dey–Greenberg–Riestenberg, we show that for certain ...

Obstructions to homotopy invariance of loop coproduct via parameterized fixed‐point theory

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract Given f:M→N$f:M \rightarrow N$ a homotopy equivalence of compact manifolds with boundary, we use a construction of Geoghegan and Nicas to define its Reidemeister trace [T]∈π1st(LN,N)$[T] \in \pi _1^{st}(\mathcal {L}N, N)$. We realize the Goresky–Hingston coproduct as a map of spectra, and show that the failure of f$f$ to entwine the spectral ...

Probabilistic Identification of Parameters in Dynamic Fracture Propagation

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT In this paper, we propose a novel multiphase approach for identifying input parameters in dynamic fracture propagation. Often, such parameters are partially known and uncertain with incomplete input data, resulting in challenges in predicting a reliable dynamic failure response.

High‐Precision Aftershock Distribution Highlights the Complex Fault Geometry of the 2024 Mw 7.5 Noto Peninsula Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We deployed 30 temporary seismic stations around the source region of the 2024 Mw 7.5 Noto Peninsula earthquake to investigate the relationship between mainshock rupture and fault geometry. Using machine learning techniques, we detected and precisely located 46,252 aftershocks, revealing several fault planes corresponding to active faults ...

Frequency‐Dependent Seismic Velocity Variations Reveal Layered Aquifer Behavior Under Groundwater Fluctuations

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Frequency‐dependent seismic velocity variations (dv/v) provide depth‐resolved constraints on aquifer behavior under groundwater fluctuations. We analyze 17 years of dv/v time series from ambient noise interferometry in the Chiang Mai Basin, Thailand, and observe contrasting dv/v behavior below and above 1 Hz. By integrating GPS, meteorological,

Lithospheric Mantle Heterogeneity Drives Delayed Magmatism and Wide Continent‐Ocean Transitions in Rifted Margins

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The formation of wide, magma‐starved continent–ocean transition (COT) zones remains incompletely understood. We use 2‐D thermo‐mechanical numerical experiments, coupling hydrous mantle melting with parameterized crustal accretion, to explore controls on magmatic lag: the delay between continental crustal break‐up and steady oceanic crustal ...

Thick Crust at Earth's Slowest Spreading Ridge: 3D Gravity Insights From Eurasian Basin, Arctic Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Eurasian Basin of the Arctic Ocean opened by ultraslow spreading along the Gakkel Ridge, yet crustal thickness has remained poorly constrained due to sparse seismic data. We present a new basin‐wide 3‐D gravity model, updated by the most comprehensive sediment thickness and seismic observations, offering the first systematic view of ...

New Insights Into the Cooling of the Oceanic Lithosphere From Surface‐Wave Tomographic Inferences

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract How oceanic plates cool and thicken with age remains a subject to debate, with several thermal models supported by apparently contradictory data. Combining a novel imaging technique that balances resolution and uncertainty with finite‐frequency surface‐wave measurements, we build tomographic model SS3DPacific to revisit the cooling style of ...
