Geophysical Prospecting, Volume 74, Issue 4, May 2026.ABSTRACT Microseismic monitoring of offshore CO2$\rm CO_2$ storage projects is likely to include some deployment of offshore sensors. To improve the value proposition of this monitoring infrastructure, it is important to consider what other information can be gained about the CO2$\rm CO_2$ storage complex and the surrounding region.

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
Advanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion
Advanced Science, Volume 13, Issue 22, 17 April 2026.Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.
