Nature Communications, Published online: 04 May 2026; doi:10.1038/s41467-026-72807-9 Hydrous magnesium silicates are key mantle water reservoirs. Here, the authors show a hydrogen site transfer in wadsleyite reduces conductivity, indicating higher transition zone water storage, and discover a double superionic state.
