Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

A Trump administration pilot program aims for three nuclear startups to reach a key milestone by July 4, 2026. Valar Atomics says it’s the first to do so—but it had some help.

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number theory to explain quantum fractals.

What sneaky invisible forces enable these instruments to locate buried treasure?

Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.

An observatory detected the first radio signal from the interstellar object 3I/Atlas. Here’s what it means.

The interstellar comet 3I/Atlas reached its closest point to the sun. Here's how to follow the rest of its journey away from our solar system.

A Turning Point USA official inaccurately claimed a high school's math department wore Halloween costumes that mocked Charlie Kirk. Those teachers are now facing a flood of online attacks and death threats.

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development.

The only craft docked at Tiangong space station has been damaged and “does not meet the release conditions for a safe manned return.”

The math behind even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major advances toward understanding it.
