Precise 3D Tracking of Highly Non‐Planar Eukaryotic Flagellar Beating Patterns Using Digital Holographic Microscopy

Small Methods, Volume 10, Issue 12, 23 June 2026.
The 3D beating dynamics of eukaryotic flagella drive motility, sensory functions, and resource acquisition, yet highly non‐planar beating patterns remain poorly characterized. Based on Digital Holographic Microscopy, holoV3C enables label‐free 3D reconstruction of such complex dynamics with 53 nm axial resolution, demonstrated on mouse sperm and ...

Gravity Wave Activity in the Stratosphere and Mesosphere During Hurricane Sam

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Multi‐instrument observations of gravity wave (GW) activity during Hurricane Sam (2021) were made using AIRS (Atmospheric Infrared Sounder) satellite data, ERA5 reanalysis, and TIMED/SABER temperature profiles. Two GW extraction methods, vertical high‐pass filtering and empirical mode decomposition, were applied to quantify wave‐induced ...

Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Identifying and Predicting Coronal Mass Ejection Occurrence: Observational Checklists for Space Weather Forecasters

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

A Reduced Dimensional Emulator for Forecasting Equatorial Spread F

Space Weather, Volume 24, Issue 6, June 2026.
Abstract A machine learning emulator has been developed to efficiently reproduce electron densities from a three‐dimensional, data‐driven, regional simulation of postsunset ionospheric irregularities associated with equatorial spread F (ESF). The simulation has previously been shown to produce accurate ESF conditions observed at the Jicamarca Radio ...
