A long-awaited study of the cosmic expansion rate suggests that when it comes to the Hubble tension, cosmologists are still missing something.

Tensors are used all over math and science to reveal hidden geometric truths. What are they?

Long explored but infrequently embraced, base 3 computing may yet find a home in cybersecurity.

Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model.

A new proof marks the first progress in decades on a problem about how order emerges from disorder.

You don’t need 0s and 1s to perform computations, and in some cases it’s better to avoid them.
