Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Buoyancy Flux and Its Environmental Modulation in the Vertical Development of Shallow Cumulus in the Central Amazon

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract This study investigates the vertical development of shallow cumulus (ShCu) clouds in the Central Amazon (CAMZ) by combining large‐eddy simulations (LES) with observational data from the GoAmazon2014/5 campaign. Analyses of turbulent kinetic energy budgets, updraft mass flux, moisture flux, and surface fluxes across cloud sizes indicate that ...

Reconstructing Marine Boundary Layer Jets Over the South China Sea Using Machine Learning

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Marine boundary layer jets (MBLJs) over the South China Sea (SCS) play a critical role in coastal heavy rainfall, yet their structure remains uncertain due to limited wind observations over the ocean. Here, we develop a U‐Net–based reconstruction framework to estimate 950‐hPa winds from satellite‐derived sea surface winds, providing a ...

Smart Face Masks as Wearable Respiratory Sensors: A Review of Sensor Technologies, Materials, and Future Directions

Advanced Healthcare Materials, Volume 15, Issue 21, 5 June 2026.
This review highlights recent advances in smart face masks that actively monitor breathing. By integrating humidity, gas, temperature, pressure, strain, and triboelectric sensors, these masks track key respiratory parameters in real time. The article summarizes sensor mechanisms, compares performance across studies, and discusses challenges and future ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,
