The Origin of the Feedstock Molecules for Life on the Hadean Earth
Angewandte Chemie International Edition, Volume 64, Issue 42, October 13, 2025.The origin of life in the Hadean eon required the formation of amino acids and nucleosides among the key molecules of life. In an often postulated strongly reducing atmosphere, HCN and its derivatives are robustly formed as plausible starting molecules. But HCN does not form in a Hadean, weakly reducing atmosphere.

Friends Not Foes: Strong Correlation between Inner Super-Earths and Outer Gas Giants
The Astrophysical Journal LettersThe connection between outer gas giants and inner super-Earths reflects their formation and evolutionary histories. Past work exploring this link has suggested a tentative positive correlation between these two populations, but these studies have been ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters
The Astrophysical JournalThe orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Assessing the C/O Ratio Formation Diagnostic: A Potential Trend with Companion Mass
The Astronomical Journal, 2023 The carbon-to-oxygen (C/O) ratio in an exoplanet atmosphere has been suggested as a potential diagnostic of planet formation. Now that a number of exoplanets have measured C/O ratios, it is possible to examine this diagnostic at a population level. Here,

A Framework for Quantifying the Degeneracies of Exoplanet Interior Compositions
, 2010 Several transiting super-Earths are expected to be discovered in the coming few years. While tools to model the interior structure of transiting planets exist, inferences about the composition are fraught with ambiguities.

Exoplanets - search methods, discoveries, and prospects for astrobiology [PDF]
, 2008 Whereas the Solar System has Mars and Europa as the best candidates for finding fossil/extant life as we know it - based on complex carbon compounds and liquid water - the 263 (non-pulsar) planetary systems around other stars as known at 15 September ...

Using Venus, Earth, and Mars to Understand Exoplanet Volatile and Climate Evolution
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract Venus, Earth, and Mars exhibit a wide range of interactions between their deep interiors, surfaces, lower and upper atmospheres, and the Sun, with commensurate variations in the nature of their atmospheres and evolution of their volatiles. By examining these worlds' characteristics and behavior, we can gain some understanding of the breadth of
