Gamma Rays Signal the Vulnerability of Forest to Extreme Drought

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Extreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge. Here, we demonstrate that airborne gamma‐ray spectrometry (GRS) of potassium (40K) decay provides a powerful proxy for subsurface constraints on water ...

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Bayesian Modeling of Crustal Azimuthal Anisotropy Supports Partial Crust–Mantle Anisotropic Decoupling in a Continental Back‐Arc, Northeast China

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract How crustal deformation responds to complex mantle flow in continental back‐arc settings remains poorly constrained. Here, we develop a Bayesian working‐likelihood approach to estimate crust‐averaged azimuthal anisotropy from P‐wave receiver functions. The method separates crust‐averaged velocity anisotropy from dip‐related apparent anisotropy

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...
