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.

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).

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

Radio-loud Exoplanet-exomoon Survey: GMRT Search for Electron Cyclotron Maser Emission
The Astronomical Journal, 2022 We conducted the first dedicated search for signatures of exoplanet–exomoon interactions using the Giant Metrewave Radio Telescope (GMRT) as part of the radio-loud exoplanet-exomoon survey.

Survey and Modeling of Windblown Ejecta Deposits on Venus
AGU Advances, Volume 6, Issue 5, October 2025.Abstract Venus' thick atmosphere rotates in the same direction as the solid body, but ∼60 times faster. This atmospheric superrotation has produced dozens of windblown ejecta deposits (“parabolas”) on the surface of Venus. The formation and modification of parabolas is an interplay between impacts, aeolian modification, and atmospheric dynamics.

Coreless Terrestrial Exoplanets [PDF]
The Astrophysical Journal, 2008 Differentiation in terrestrial planets is expected to include the formation of a metallic iron core. We predict the existence of terrestrial planets that have differentiated but have no metallic core--planets that are effectively a giant silicate mantle.

Evidence for a Natural Limit to Electron Space Radiation: An Application of Benford's Law
Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract Recent research has highlighted observational evidence for a natural limit to the severity of energetic electron differential fluxes in the Van Allen radiation belts. Here, we analyze the occurrence distributions of electron differential fluxes from the entire Van Allen Probes mission (2012–2019) to further investigate the energy dependence of
