Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Foam Injection Molded Stereocomplex PLA: Processing, Thermal Behavior and Foam Structure

Journal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
The processing of stereocomplex poly(lactic acid) (sc‐PLA) via continuous compounding followed by thermoplastic foam injection molding is investigated. A controlled two‐stage cooling strategy effectively promotes sc‐dominated crystallization of the granulates.

Nightside Auroral Arcs Near the Electron Isotropy Boundary: TRACERS–THEMIS–MetOp Observations

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Particle precipitation is the ultimate driver of aurorae. Monoenergetic (∼keV) electrons accelerated above the ionosphere produce discrete auroral forms and are associated with field‐aligned currents that govern magnetosphere–ionosphere (MI) coupling.

A Low Cost, Fully Sensorless Dual Axis PV Tracker Using Astronomical Ephemerides and Discrete Actuation

Energy Technology, Volume 14, Issue 11, November 2026.
A fully sensorless dual‐axis solar tracker based on astronomical ephemerides and postal‐code geographic localization is developed and validated. The proposed discrete tracking strategy increases photovoltaic energy yield while minimizing actuator energy consumption, hardware complexity, and maintenance requirements, providing a practical and cost ...

Carbon‐Transfer Bottlenecks in Irrigated Oasis Agriculture: A Diagnostic Framework for Soil Organic Carbon Retention

Food and Energy Security, Volume 15, Issue 6, November/December 2026.
ABSTRACT Sustaining food production in arid regions increasingly depends on irrigated oasis agriculture, yet high productivity in these systems does not guarantee durable soil organic carbon (SOC) retention. This integrative narrative review asks why this yield–carbon decoupling occurs in irrigated oasis croplands and how it can be addressed through ...

Statistical evaluation of nylon chemical recycling through acidolysis

Polymer International, Volume 75, Issue 11, Page 1125-1132, November 2026.
Sustainable PA6 recycling through acidolysis enabled temperature‐driven depolymerization, modeled by regression analysis. Recycled products successfully replaced up to 30% monomer while preserving PA6 chemical composition or crystalline structure. Abstract This study focuses on the sustainability of plastics reporting the recycling of polyamide (PA ...

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

Hysteretic Dynamics of Stream Network Expansion and Contraction Revealed Through High‐Resolution Integrated Hydrological Modeling

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract As landscapes cycle through wetting and drying, stream networks expand and contract, driving material export and biogeochemical transformations with important implications for water quality and ecosystem function. Because it is challenging to measure the extent (L) $(L)$ of the active network, streamflow (Q $Q$) is often used as a proxy ...

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.
