Fast Breakdowns Observed in the Initial Leaders of Two Energetic Compact Strokes

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We have observed 1 fast positive breakdown (FPB) and 20 fast negative breakdowns (FNBs) for the first time in the initial leader of two energetic compact strokes (ECSs) using a broadband interferometer. It was found that the FPB propagated upward over a distance of 30 m with a speed of 1.2×107m/s $1.2\times {10}^{7}\mathrm{m}/\mathrm{s ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Stromal‐Derived IL‐8 Promotes M2 Macrophage Polarization via the RhoA/MRTF‐A/SRF Transcriptional Axis to Impair CD8+ T Cell Cytotoxicity in Lung Cancer

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
In the recondite pulmonary neoplastic milieu, DESMIN+ cancer‐associated fibroblasts function as the paramount stromal source of IL‐8, precipitating a deleterious immunological metamorphosis by engaging CXCR2 receptors on the myeloid lineage. This paracrine stimulus triggers a mechanotransduction cascade characterized by RhoA‐dependent actin ...

Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

An Implantable Phototriggered Prodrug Depot Patch Enables Actively Programmable Drug Release for Post‐Myocardial Infarction Therapy

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
An implantable phototriggered prodrug depot patch (iPDP) is presented that enables actively programmable drug release post‐implantation. Covalently conjugated prodrug ensures minimal leakage; illumination parameters serve as a code to precisely control dose per release.

Regional Models for Postfire Debris‐Flow Likelihood and Rainfall Thresholds Across the Western United States

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Using a newly expanded debris‐flow inventory, we calibrate a new set of region‐specific logistic models for predicting the likelihood of, and rainfall thresholds for, runoff‐generated postfire debris flows. The updated models consistently outperform a previous model and can improve assessment of debris‐flow hazards for burned areas across the western ...

Quaternary structures of Streptococcus pneumoniae nucleoside diphosphate kinase: From hexamers to supramolecular assemblies

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract The nucleoside diphosphate kinase (NDK) is a key enzyme that controls the balance of nucleotide pools in all living organisms. Beyond this fundamental role, NDKs exert pleiotropic effects in many cellular processes, including cell development, signal transduction, differentiation, tumor metastasis, and gene expression. The quaternary structure

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

open access: yessteel research international, Volume 97, Issue 9, Page 4684-4713, September 2026.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Wind Turbine Blade Crack Detection and Assessment in Images Using Machine Learning

open access: yesWind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT As the wind energy industry matures, inspection of wind turbine blades (WTBs) is shifting from a manual process involving rope access and grading of damage, towards unmanned aerial vehicle (UAV) photography and artificial intelligence‐aided processing of data.
