Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, Volume 3, Issue 3, Page 452-501, September 2026.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

High Resolution Field Observations of Shoreward Sediment Transport Within the Wave Bottom Boundary Layer on a Sandy Beach

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Acoustic Detection of Underwater Air Bubbles Generated by Breaking Waves in an Antarctic Polynya

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The Southern Ocean is a significant sink for anthropogenic CO2 in the atmosphere. The pelagic regions north of sea ice areas primarily absorb atmospheric CO2 via biological productivity and air‐sea gas exchange. The latter is enhanced by the bubbles generated by breaking waves.
