The South Atlantic Anomaly — a growing weak spot in Earth’s magnetic shield — has expanded by nearly half the size of continental Europe since 2014, with especially intense weakening now occurring near Africa. At the same time, magnetic strength is rising over Siberia and fading over Canada, reflecting powerful changes unfolding deep inside Earth’s core.

Antelope bone fragment in rock from the 3-million-year-old early human site, Makapansgaat (South Africa). Its bone marrow cavity is filled with a white carbonate-rich precipitate. Paleometabolomics can describe the well-being of that animal and provide ultrafine-scale reconstructions of its paleoecology. Credit: Timothy Bromage and Bin Hu, NYU College of Dentistry
