Lunar Highland Preserves Meteoritic-iron-rich Materials in the Earth–Moon System
The Astrophysical JournalMeteoritic impacts over 4.5 billion yr have modified the composition and properties of the Earth and Moon’s surfaces. The low-iron lunar highlands (FeO ∼ 5 wt%) may provide insights into the contribution of meteoritic iron to the Earth–Moon system ...

Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith
The Planetary Science JournalLunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons.

Local Elites in Chile's Pisco Valley: Dispossession, Legal Mobilisation and Intertwined Citizenship
Journal of Agrarian Change, EarlyView.ABSTRACT In countries in the Global South, citizenship is often closely tied to access to water and land ownership. In Latin America, the literature has primarily explored social mobilisation and identity reconfiguration in response to development‐driven processes of land and water dispossession affecting peasants, rural and Indigenous communities ...

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 ...

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.

Ejecta Blankets at Small Craters on the Moon
The Planetary Science JournalImpact-derived ejecta covers most of the lunar surface, originating from recent impacts through to the beginning of the geologic record. Despite how common ejecta is, accurate measurements of ejecta thickness are difficult to obtain, and existing ...
