Anatomical Study and CT Scan of the Scleral Ring in the Little Owl (Athene noctua)

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
The scleral ring in Athene noctua predominantly consists of 15 quadrilateral ossicles, with a rare anatomical variation of 16 ossicles observed unilaterally in one specimen. Structural Morphology: The ring displays a distinct bipartite architecture, featuring an anterior tubular segment with a near‐circular cross‐section and a posterior funnel‐shaped ...

Effect of Boulder‐Size Distributions on Thermally Derived Rock Abundances on the Moon

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Rock abundance, defined as the surface's fractional area covered by rocks, is used to characterize the Moon's regolith, decipher its impact history, and assess potential landing sites. By definition, it should be agnostic to rock‐size distributions. However, it has been suggested that rock abundances, derived from surface temperatures measured

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.

Visible‐Shortwave Infrared (VSWIR) Spectral Parameters for the Lunar Trailblazer High‐Resolution Volatiles and Minerals Moon Mapper (HVM3)

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Lunar Trailblazer smallsat mission High‐resolution Volatiles and Minerals Moon Mapper (HVM3) science instrument was designed to acquire targeted spectral image cubes of the lunar surface at visible to shortwave infrared (VSWIR) wavelengths (0.6–3.6 μm) in an effort to understand the distribution, abundance, and form (OH, H2O, ice) of lunar
