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.

Four mathematicians have found a new upper limit to the “Ramsey number,” a crucial property describing unavoidable structure in graphs.

In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape.

Is it possible to fill space “cubically” with shapes that act like spheres? A proof at the intersection of geometry and theoretical computer science says yes.

Reports that the James Webb Space Telescope killed the reigning cosmological model turn out to have been exaggerated. But astronomers still have much to learn from distant galaxies glimpsed by Webb.

After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.

For Lisa Kaltenegger and her generation of exoplanet astronomers, decades of planning have set the stage for an epochal detection.

A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.
