Recognition of fossil keratose sponges in carbonates using petrographic and machine‐learning classification

Sedimentology, Volume 73, Issue 6, Page 2246-2280, October 2026.
ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

On the Timescales of Atmospheric Adjustments to Contrail Cirrus Formation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Condensation trails (contrails) that evolve into contrail cirrus may constitute the largest contribution to aviation's climate impact. However the strength and timescales of the adjustments of the upper atmospheric water budget to contrail formation are poorly known. Thanks to multiple simulations with the ICOLMDZ climate model, the relatively

Escalating Uncertainty Under Increasing Risk in Compound Heat and Precipitation Extremes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Projection uncertainty fundamentally constrains climate adaptation, yet its evolution in compound heat and precipitation extremes (CHPE) remains poorly understood. Here we quantify CHPE uncertainty using 14 CMIP6 models and two single‐model initial‐condition large ensembles.

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14964-15009, 15 September 2026.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Hierarchical Assembly as a Design Principle: Structure–Property Relationships Linking Biological Architectures to Functional Aggregate Materials

Aggregate, Volume 7, Issue 9, September 2026.
Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

Through the Looking Glass: Uncovering the EU's Gendered Foreign Policy to Afghanistan

Contemporary European Politics, Volume 4, Issue 3, September 2026.
ABSTRACT Afghanistan has consistently ranked among the most challenging contexts for the promotion of women's rights. This situation has intensified with the Taliban's return to power in August 2021 and the subsequent consolidation of what has been termed a system of gender apartheid.

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

Numerical Aspects of Turbulent Blood Flow in Aorta: A Systematic Review

Engineering Reports, Volume 8, Issue 9, September 2026.
The aim of this systematic review is to systematize the methodological approaches used in the state‐of‐the‐art literature, including the choice of turbulence models, validation methods, as well as the identification of the main hemodynamic parameters characterizing turbulent flow.

Mathematical Modeling of Pulse‐Seeded Metapopulation Dynamics for Andes Hantavirus Border Dispersal

Engineering Reports, Volume 8, Issue 9, September 2026.
A pulse‐seeded metapopulation SEIR model for Andes hantavirus maritime dispersal shows that heterogeneous quarantine compliance determines secondary outbreak risk. The weakest‐compliance country governs global containment, while uniform compliance above ∼65%$$ \sim 65\% $$ reduces the global reproduction number below unity.
