A Novel Distributed Sensor Network to Assess Wind Turbine Blade Acoustics for Structural Health Monitoring

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT To reduce the need for scheduled wind turbine blade inspections and large‐scale repairs, a novel distributed acoustic sensing system for monitoring the structural health of wind turbine blades is proposed. This integral passive monitoring system utilizes a sparse array of in‐blade multimodal sensors and a single blade‐external downtower sensor,

Chemically Welded, Capillary‐Printed Ion‐Selective Membranes for Durable Solid‐State Chloride Sensors in Dynamic Marine Environments

Advanced Sensor Research, Volume 5, Issue 9, September 2026.
Chemically welded capillary printing creates durable chloride‐selective membranes that resist drift and delamination. The integrated solid‐state sensor reliably tracks tidal salinity variations, enabling scalable, low‐cost marine monitoring across distributed networks. ABSTRACT Salinity is a critical environmental parameter governing ocean circulation,

Abrupt Onset and Persistent Downstream Effects of Acid Rock Drainage on Rivers Across Northwest Arctic Alaska

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Arctic streams and rivers are increasingly vulnerable to degradation from permafrost thaw that releases toxic elements via natural acid rock drainage. However, the spatial and temporal evolution of acid rock drainage on river chemistry across diverse mineral settings remain poorly constrained.

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 512-529, September 2026.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.
