The mathematical physicist Robbert Dijkgraaf and host Steven Strogatz discuss the frontiers of string theory and why space and time might not be the most fundamental things in the universe.

Neural networks have been taught to quickly read the surfaces of proteins — molecules critical to many biological processes.

To distinguish between fundamentally different objects, mathematicians turn to invariants that encode the objects’ essential features.

Mathematicians try to figure out when problems can be solved using current knowledge — and when they have to chart a new path instead.

By chewing on the problems posed by “extremal” black holes, physicists have exposed a surprising and universal connection between energy and entropy.

Neuroscientists could use brain waves to spur immune cells into action against the disease — but the process is almost too fantastic to believe.

Studies of collective behavior usually focus on how crowds of organisms coordinate their actions. But what if the individuals that don’t participate have just as much to tell us?

After translating some of math’s complicated equations, researchers have created an AI system that they hope will answer even bigger questions.

It took Lisa Piccirillo less than a week to answer a long-standing question about a strange knot discovered over half a century ago by the legendary John Conway.

The mathematical physicist Robbert Dijkgraaf and host Steven Strogatz discuss the frontiers of string theory and why space and time might not be the most fundamental things in the universe.

Readers poked holes in our paradoxical April Fools’ Day claims about perpetual energy and whether this puzzle solution would ever be published.

Researchers struggle to incorporate ongoing evolutionary discoveries into an animal classification scheme older than Darwin.
