Thousand‐Kilometer‐Scale Wavelike Undulations in Ionospheric Plasma Bubble Lifetime and Development Over Wide Longitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The irregularities of ionospheric plasma bubbles (EPBs) sequentially generated over wide longitudes are expected to share similar lifetime under normal conditions. In this study, we report a special case where the EPB irregularity lifetime over wide longitudes showed a quasi‐wavelike undulation pattern with wavelength of ∼3,000 km, that is ...

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.

First LiDAR Observation of Quasi‐Periodic Structures in Mid‐Latitude E‐Region Meteoric Ca+ Layers

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We report the first LiDAR observations of continuous quasi‐periodic (QP) metal density structures in mid‐latitude E‐region meteoric Ca+ layers using an all‐solid‐state LiDAR system in Beijing (40.4°N, 116.0°E). These QP Ca+ structures, with periods of 2–30 min and vertical wavelengths of ∼2–15 km, were primarily observed above 100 km.

Resonant Vibrational Excitation and Overtone Vibrational Emissions of Nitric Oxide (NO) in Sub‐Auroral Ion Drift (SAID) Region: A Source of STEVE Continuum Emission

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract At elevated electron temperature (Te≥3000°K ${T}_{e}\mathit{\ge }3000\mathit{{}^{\circ}}\mathrm{K}$) inside Sub‐Auroral Ion Drift, resonant vibrational excitation (RVE) increases the vibrationally excited (v≥8 $v\mathit{\ge }8$) nitric oxide (NO) population in the E‐region, which undergoes overtone vibrational emissions (Δv≥8 ${\Delta }v ...

OBUSight: Clinically Aligned Generative AI for Ophthalmic Ultrasound Interpretation and Diagnosis

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
OBUSight, a clinically aligned generative AI model that jointly generates reports and predicts diseases through multimodal semantic alignment, was trained and validated on a large multicenter dataset. OBUSight outperformed eight state‐of‐the‐art models, provided clinically reliable reports, enhanced diagnostic efficiency, and achieved performance ...
