A closed chemo‐mechanical feedback system is constructed using a GOx/urease core–shell hydrogel with pH‐responsive microcapsules. Proton generation triggers urea release, activating urease and restoring pH, resulting in autonomous swelling–deswelling oscillations.

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 ...

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Abstract In situ observations of thermospheric composition have long been scarce, limiting our understanding of the upper atmosphere and its response to space weather. This study focuses on the Neutral Gas Mass Spectrometer (NGMS) onboard the TM19 and TM20 satellites of China's TianMu‐1 constellation, presenting the first systematic elaboration of its ...
