Scientists used artificial intelligence and millions of seismic records to discover six mysterious regions near the Earth's core-mantle boundary, offering new insights into planetary dynamics.

Deep beneath the northeastern United States, a massive geological mystery has been hiding for millions of years. Scientists call it the "Northern Appalachian Anomaly" - a region hundreds of kilometers wide where rocks in the Earth's mantle are abnormally hot. A 2025 study even suggested that this mass is slowly moving southwest, and if the model is correct, its center could pass under the New York...
