APXS Derived Geochemistry of Shallow Water Lens Bodies Within the Mirador Formation, Gale Crater, Mars—Evidence for Intermittent Wet Periods and Implications for the Water Record

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mount Sharp group in Gale crater is typically interpreted to record a progressive change (with increasing elevation) from wetter fluvio‐lacustrine environments to dry, eolian environments. This shift has been linked to orbital evidence for a global change in environmental and depositional conditions leading to an overall drying out of Mars.

Effects of Mineralogy and UV Radiation on the Detectability of Amino Acids Within the Martian Regolith: The Case for a Combined Chromatographical and Spectroscopical Approach

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Amino acids are an extremely heterogeneous group of biomolecules essential for life on Earth. Their biosignatures are expected to be easily degraded on the Martian surface as the absence of a thick atmosphere and a magnetosphere leads to most of the solar radiation directly reaching its surface.

Felsic Magmatism on Venus Generated by Crustal Recycling and Melting

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The observation of low viscosity lava flows and shield volcanoes on radar images, combined with X‐ray fluorescence analyses performed by Soviet landers, strongly suggests that Venus's crust is primarily basaltic. However, near‐infrared emissivity data from the Galileo and Venus Express missions indicate that crustal plateaus may be ...

Nature‐inspired hierarchical materials

Journal of the American Ceramic Society, Volume 108, Issue 11, November 2025.
Nature serves as a wonderful school for materials science, demonstrating how biological organisms craft hierarchical structures and multifunctional properties using limited, locally available resources. This process addresses complex design challenges while promoting sustainability.
