Foreshock Migration Preceding the 2025 Mw 8.8 Kamchatka Earthquake: Insights From Single‐Station Observations

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station. Our results reveal a southwestward migration of foreshocks toward the mainshock epicenter through multiple stages, with a migration speed of ∼7.0 km ...

Introducing Regularization Constraints Into Combination of GRACE Monthly Terrestrial Water Storage Changes

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Gravity Recovery and Climate Experiment (GRACE) observation data processed by various institutions yields somewhat different spherical harmonic solutions, which are further used to derive terrestrial water storage (TWS) changes. Combining TWS solutions from different institutions helps to refine the effective signal while removing noise.

Robust Inverse Material Design With Physical Guarantees Using the Voigt‐Reuss Net

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT We apply the Voigt‐Reuss net, a spectrally normalized neural surrogate introduced in [38], for forward and inverse mechanical homogenization with a key guarantee that all predicted effective stiffness tensors satisfy Voigt‐Reuss bounds in the Löwner sense during training, inference, and gradient‐driven optimization.

Understanding bio‐based polymers: A study of origins, properties, biodegradation and their impact on health and the environment

FEBS Open Bio, Volume 16, Issue 4, Page 635-652, April 2026.
This review provides an overview of bio‐based polymer sources, their unique functional properties and their environmental impact, and addresses their role as sustainable alternatives. It discusses end‐of‐life options, including composting and anaerobic digestion for renewable energy.

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...
