The Atlantic Ocean did not spring into existence in a sudden tectonic snap; its earliest pulse can now be traced through a set of one-kilometer-long mud waves lying more than 3,000 feet below today’s seafloor some 250 miles west of Guinea-Bissau. New seismic profiles and cores date these colossal ripples to roughly 117 million years old, which shifts the birth …

A giant blob of abnormally hot rock beneath the Appalachian Mountains formed when Greenland separated from North America around 80 million years ago, new research suggests. Scientists previously thought that this hot zone, known as the Northern Appalachian Anomaly, was left over after North America broke away from Africa 180 million years ago, but this theory does not stand up …

From Earth’s perspective, the junction of the disks resembles the number eight lying down, similar to the infinity symbol (∞). Because of this resemblance, the researchers—who are based at the universities of Yale and …
