    "headline": "AI Analysis Reveals Six Hidden Structures Deep Within Earth's Core",
    "dek": "Scientists used AI to identify six massive geological structures 2,900 km beneath Earth's surface.",
    "prose": "Scientists identified six previously unknown geological structures located approximately 2,900 kilometers beneath the Earth's surface at the boundary between the mantle and the outer core. [^1]\n\nAn artificial intelligence algorithm was used to identify weak signal dispersions that were previously confused with background noise. [^2]\n\nResearchers processed more than two million precursor PKP seismic waves recorded between 1990 and 2024 from earthquakes with a magnitude greater than 6.0. [^3]\n\nThe discovery changes the understanding of internal planetary dynamics, thermal convection, and the evolution of tectonic plates that have disappeared over millions of years. [^4]\n\nDeep learning algorithms were utilized to identify small variations in seismic waves and distinguish real signals from noise and monitoring network limitations. [^5]\n\nThe newly discovered structures are located at a depth of approximately 2,900 kilometers within the Earth. [^6]",
