The futuristic manifolds of REM sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...

Near-infrared Photometry of the Moon’s Surface with Passive Radiometry from the Lunar Orbiter Laser Altimeter (LOLA)

The Planetary Science Journal
Examining the reflectance of the Moon’s surface across a broad range of viewing geometries through photometric analysis can reveal physical and geological properties of its regolith.

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Meteoroid flux at sub-meter scales is homogeneous across the Lunar nearside and farside

Communications Earth & Environment
The spatial heterogeneity of meteoroid impact flux has shaped the space weathering environment across the lunar surface, driving key evolutionary processes such as crater degradation, regolith gardening, and soil grain exposure.

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Temporal Variations of 222Rn Density Distributions in the Lunar Exosphere

The Planetary Science Journal
Because of radiogenic processes, the lunar interior is a source of rare gases like helium ( ^4 He), argon ( ^40 Ar), and radon ( ^222 Rn) that might be released continuously, or impulsively during moonquakes. The detection of radon is therefore important

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

Meteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Mapping Potential Hazards and Identifying Sampling Points within Lunar South Polar Region Areas of Interest

The Planetary Science Journal
The lunar south polar region is an area of interest geologically, and so it is a target for many future missions. These target areas are being investigated in detail, particularly in relation to the illumination conditions, Earth visibility, thermal ...
