When the forces of plate tectonics tear continents apart, it’s an incredibly violent process, unfolding in slow motion. It was also thought to be very local: Magma from hot, rising mantle rock seeds volcanoes along the rift zone, while the far-removed cold interiors of continents remain intact.
Microscopic algalike fossils from China reported early this year astounded evolutionary biologists with their extreme age. Dated at 1.6 billion years old, the specimens suggest one of the hallmarks of complex life—multicellularity—arose far earlier than previously thought.
For 98 years, physicists knew of two types of permanently magnetic materials. Now, they’ve found a third. In familiar ferromagnets such as iron, unpaired electrons on neighboring atoms spin in the same direction, magnetizing the material so that, for example, it sticks to a refrigerator. Antiferromagnets such as chromium have zero overall magnetism, but they possess an atomic-scale magnetic pattern, with neighboring electrons spinning in opposite directions. Novel altermagnets—hypothesized 5 years ago—share aspects of both.
