Application and Evaluation of a NOAA GFS‐Driven Air Quality Model Using CMAQv5.4 and High‐Resolution Emissions: FIREX‐AQ 2019

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The National Air Quality Forecast Capability (NAQFC) provides numerical forecasting guidance of air quality up to 72 hr ahead over the United States. In this study, we evaluate the changes in its prediction skills by updating the Community Multiscale Air Quality (CMAQ) modeling system from version 5.3.1 to 5.4 and utilizing a high‐resolution 1‐

Pseudo‐Radar Reflectivity by Applying U‐Net Models to Global Passive Microwave Brightness Temperatures

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

TMEM92 shields DDX3X from TTC3‐mediated degradation to confer chemoresistance in triple‐negative breast cancer

open access: yesClinical and Translational Medicine, Volume 16, Issue 5, May 2026.
TMEM92 protects DDX3X from degradation by the E3 ligase TTC3, promoting TNBC cell proliferation and tumour growth. Depleting TMEM92 not only suppresses tumour growth but also sensitises cells to cisplatin, suggesting that targeting this axis is a potential therapeutic strategy.

Mass mortality of saguaros (Carnegiea gigantea) from windthrow: A rare, demographic disturbance in a desert ecosystem

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to
