Hunger Game: Is Honesty Between Animals Always the Best Policy?

Game theorists have developed a new model of communication among animals. It suggests evolution will produce a situation in which members of a species are honest most of the time, but not always.


Alice and Bob Meet the Wall of Fire

If a new hypothesis about black hole firewalls proves correct, at least one of three cherished notions in theoretical physics must be wrong.

Classical Computing Embraces Quantum Ideas

Computer scientists are finding that “thinking quantumly” can lead to new insights into long-standing problems in classical computer science, mathematics and cryptography, regardless of whether quantum computers ever materialize.


Privacy by the Numbers: A New Approach to Safeguarding Data

A mathematical technique called “differential privacy” gives researchers access to vast repositories of personal data while meeting a high standard for privacy protection.


A Primordial Nucleus Behind the Elements of Life

Using supercomputers and new mathematical techniques, physicists are working to reveal how the Hoyle state atomic nucleus gives rise to the light elements that enable life, and how it drives the evolution of stars.

As Supersymmetry Fails Tests, Physicists Seek New Ideas

As the elegant theory of supersymmetry continues to fail experimental tests, physicists debate whether to change course and what the future holds for particle physics.


Getting Into Shapes: From Hyperbolic Geometry to Cube Complexes and Back

Thirty years after William Thurston articulated a grand mathematical vision, a proof by Ian Agol marks the end of an era in the study of three-dimensional shapes.
