Computational Fluid Dynamics Reveals Mass Transfer Limitations in a Pilot‐Scale Microbial Electrolysis Cell

Water Environment Research, Volume 98, Issue 6, June 2026.
A computational fluid dynamics (CFD) model of a 1‐m3 microbial electrolysis cell (MEC) reveals that pilot‐scale MEC performance is governed by hydrodynamics and external mass transfer rather than intrinsic bioelectrochemical kinetics. Recirculation mitigates limitations in external mass transfer, increasing acetate removal from ~16% to ~48%.

Diagnosing Kinetic Energy Scaling Using Lagrangian and Eulerian Metrics in Different Dynamical Regimes of the North Atlantic

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Understanding the multiscale dynamics of ocean surface turbulence requires diagnostics that reliably characterize variability at scales both larger and smaller than the Rossby radius of deformation. This study evaluates the consistency and interpretability of second‐order velocity structure functions derived from Eulerian and Lagrangian ...

Effect of Unstable Water Flow on Grain Transport: Insights From Laboratory Experiments Under Reduced Atmospheric Pressure

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Nowadays, Mars presents an environment characterized by low atmospheric pressure (∼6 mbar), which profoundly alters water‐driven surface processes known from Earth. Under these conditions, water rapidly boils, cools, and stabilizes near the triple point, often freezing, which strongly limits its ability to transport sediment.

A Multi‐Scale Probabilistic Machine Learning Model for Balanced and Unbalanced Sea Surface Height Decomposition

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Sea surface height (SSH) reflects a superposition of balanced motions (BM) and unbalanced motions (UBM), which play distinct roles in ocean dynamics and energetics. The Surface Water and Ocean Topography (SWOT) satellite provides two‐dimensional SSH maps at spatial resolutions where BM and UBM coexist, but its 21‐day repeat cycle precludes ...

A Turbulence‐Informed Parameterization of Phase Partitioning in Stratiform Mixed‐Phase Clouds for the LMDZ Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract High‐latitude clouds, present over the Arctic Ocean, the Southern Ocean and the Antarctic continent, are very often mixed‐phase clouds (MPCs), that is, composed of both supercooled liquid droplets and ice crystals. Despite being essential for the climate of the poles, they remain a major modeling challenge for climate models. In this study, we

Circularly Expanding Ring‐Shaped Pulsating Aurora Visualizing the Source of Plasma Waves in Space

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Pulsating aurorae are prominent auroral emissions in the polar regions, typically occurring in the morning hours during the recovery phase of auroral substorms. These aurorae usually consist of round‐shaped patches of emission, with luminosity that pulsates at intervals ranging from less than a second to several tens of seconds.

Rotation‐Controlled Diurnal Evolution of Uranus' Asymmetric Bow Shock at Equinox

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Uranus possesses the most extreme magnetic and rotational geometry in the solar system, resulting in a uniquely dynamic and asymmetric interaction between its magnetosphere and the solar wind. Here we investigate the diurnal evolution of the Uranian bow shock (BS) at equinox using global multifluid magnetohydrodynamic simulations constrained ...

Magnetic Fabric: A Geophysical Approach for Identifying China's Neolithic Rammed Earth

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Accurate identification of rammed‐earth remains is essential for understanding early social complexity in Neolithic China. However, scientific methods for identifying rammed‐earth materials in Chinese prehistoric archeology remain limited, and identification still rely largely on field observations.

Ion Anisotropy in Earth's Magnetotail: Importance of High‐Energy Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The reconfiguration of the magnetotail current sheet during substorms often includes the formation of a thin current sheet (TCS) with a strong magnetic field line tension force. This force cannot be balanced by isotropic plasma pressure gradients, and force balance in such a TCS requires ion anisotropy and/or agyrotropy of plasma pressure.
