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.

Prehistoric elephant footprints documented for first time in Murcia’s fossil dunes

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

Stick-slip events in the earth cause damage like this, but limited data from these relatively rare earthquakes makes them difficult to model with machine learning. Transfer learning may provide a path to understanding when such deep faults slip. Credit: Dreamstime
