Twenty years ago, physicists set out to investigate a mysterious asymmetry in the proton’s interior. Their results, published today, show how antimatter helps stabilize every atom’s core.

A new proof demonstrates the power of arithmetic dynamics, an emerging discipline that combines insights from number theory and dynamical systems.

The learning algorithm that enables the runaway success of deep neural networks doesn’t work in biological brains, but researchers are finding alternatives that could.


Sometimes the act of solving a puzzle can itself reveal hidden insights.

By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more.

Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism.


Four mathematicians have cataloged all the tetrahedra with rational angles, resolving a question about basic geometric shapes using techniques from number theory.

In the fight against COVID-19, disease modelers have struggled with misunderstanding and misuse of their work. They have also come to realize how unready the state of modeling was for this pandemic.


The relationships among the properties of flexible shapes have fascinated mathematicians for centuries.

Since they can’t prod actual universes as they inflate and bump into each other in the hypothetical multiverse, physicists are studying digital and physical analogs of the process.
