The identification and biogeochemical interpretation of fossil magnetotactic bacteria [PDF]
, 2008 Magnetotactic bacteria, which most commonly live within the oxic-anoxic transition zone (OATZ) of aquatic environments, produce intracellular crystals of magnetic minerals, specifically magnetite or greigite.

Oxidation of the Interiors of Carbide Exoplanets
The Planetary Science Journal, 2020 Astrophysical measurements have shown that some stars have sufficiently high carbon-to-oxygen ratios such that the planets they host would be mainly composed of carbides instead of silicates.

Sea-floor tectonics and submarine hydrothermal systems [PDF]
, 2005 The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

The Nominal Ranges of Rocky Planet Masses, Radii, Surface Gravities, and Bulk Densities
The Astrophysical Journal, 2023 The two primary observable quantities of an exoplanet—its mass and radius—alone are not sufficient to probe a rocky exoplanet’s interior composition and mineralogy.
