Wall Street’s market forecasts are too tepid. The S&P 500 could rally next year on a combination of AI growth and deregulation. But investors should prepare for a wilder ride.
The Federal Reserve could find it harder to balance growth and inflation next year, given the incoming Trump administration’s policies. So far, the forecast looks sunny.

Mantle waves sculpt the continents
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.
Multicellularity came early for ancient eukaryotes
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.
A new type of magnetism emerges
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.
Not even the most optimistic of rebels could have predicted the rapid collapse, last weekend, of the Assad dynasty that ruled Syria with an iron fist for more than 50 years. Yet while there was relief and joy both inside Syria and among the nation’s vast displaced diaspora, it was also accompanied by apprehension over what might come next.
