Terrestrial ages of Antarctic meteorites: Implications for concentration mechanisms [PDF]
, 1986 Antarctic meteorites differ from meteorites fallen in other places in their mean terrestrial ages. Boeckl estimated the terrestrial half-life for the disintegration of stone meteorites by weathering under the climatic conditions of the Western United ...

Life, 2013 The emergence of mechanisms for phosphorylating organic and inorganic molecules is a key step en route to the earliest living systems. At the heart of all contemporary biochemical systems reside reactive phosphorus (P) molecules (such as adenosine ...

On Serine Octamer Substitution Reactions
Rapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.ABSTRACT Rationale Monomeric amino acids substitute into the ionized serine octamer (Ser8), a magic number cluster that exhibits chiral behavior. Small biomolecules, such as amino acids (AA), substitute into the octamer enantioselectively, giving Ser7AAH+ and Ser6AA2H+ favoring clusters of all L‐ or all D‐chirality.

Sources of Extraterrestrial Rare Earth Elements: To the Moon and Beyond
Resources, 2017 The resource budget of Earth is limited. Rare-earth elements (REEs) are used across the world by society on a daily basis yet several of these elements have <2500 years of reserves left, based on current demand, mining operations, and technologies ...

The Astrophysical Formation of Asymmetric Molecules and the Emergence of a Chiral Bias
Life, 2019 The biomolecular homochirality in living organisms has been investigated for decades, but its origin remains poorly understood. It has been shown that circular polarized light (CPL) and other energy sources are capable of inducing small enantiomeric ...

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
