Memories may affect how well the brain will learn about future events by shifting our perceptions of the world.

For the first time, mathematicians have proved that planetary orbits in a solar system will always be unstable.

A new theory describes how particle interactions fuel fast magnetic reconnection, the process behind solar flares and other astrophysical jets.

Today’s language models are more sophisticated than ever, but they still struggle with the concept of negation. That’s unlikely to change anytime soon.

Minhyong Kim is leading a new initiative called Mathematics for Humanity that encourages mathematicians to apply their skills to solving social problems.

In two landmark experiments, researchers used quantum processors to engineer exotic particles that have captivated physicists for decades. The work is a step toward crash-proof quantum computers.

A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.

If we want to understand complex constructions, such as ourselves, assembly theory says we must account for the entire history of how such entities came to be.

A new phase of matter called a “time crystal” plays with our expectations of thermodynamics. The physicist Vedika Khemani talks with Steven Strogatz about its surprising quantum behavior.
