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

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

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

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.

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

“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 fabric of what binds America together at this point is basically on its final thread,” one source tells WIRED.

A federal contracting database lists an ICE payment for $61,218 with the payment code for “guided missile warheads and explosive components.” But it appears ICE simply entered the wrong code.

Unusually warm ocean temperatures fueled one of the worst hurricanes on record. New research finds climate change increased the storm’s likelihood.

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.

This week on Uncanny Valley, we break down how one of the most common card shufflers could be altered to cheat, and why that matters—even for those who don’t frequent the poker table.

At an airport in South Carolina on Thursday, US representative Nancy Mace called police officers “fucking incompetent” and berated them repeatedly, according to an incident report.
