Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 48, November 24, 2025.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

Moderate Thermal Conductivity of Fe‐Ni‐Si Alloy at Earth's Core Conditions: Implications for Core Thermal Evolution and Geodynamo

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Earth's presently‐active magnetic field is thought to be generated by geodynamo via convection of liquid outer core, primarily composed of Fe alloyed with Ni and light elements, for example, Si. Core thermal conductivity critically controls its thermal evolution, dynamics, and available energy (thermal vs. compositional) powering the geodynamo
