Mathematicians have proved that copies of smaller graphs can always be used to perfectly cover larger ones.

The mathematical biologist Corina Tarnita explains to host Steven Strogatz how quantitative modeling solved the mystery of fairy circles.

By watching for a special kind of flare, astronomers have identified the fingerprints of an Earth-size planet orbiting a distant star.

Explore our surprisingly simple, absurdly ambitious and necessarily incomplete guide to the boundless mathematical universe.

For decades, scientists have been intrigued by tiny viruses whose genetic material can be read both forward and backward. New research begins to explain this puzzling property.

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.

Don’t be misled by the bloodthirsty names of immune cells. Mounting research shows that the cells also fine-tune tissues and help the body heal.

Mathematicians have studied knots for centuries, but a new material is showing why some knots are better than others.

The apparent paradox of the chicken and the egg smells like “turtles all the way down.” This puzzle shows how biology and physics can overcome infinite regress.
