A New Cosmic Tension: The Universe Might Be Too Thin
Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?
The Mathematical Structure of Particle Collisions Comes Into View
Physicists have identified an algebraic structure underlying the messy mathematics of particle collisions. Some hope it will lead to a more elegant theory of the natural world.
An Alternative to Dark Matter Passes Critical Test
Modified gravity theories have never been able to describe the universe’s first light. A new formulation does.
Cosmic Rays May Explain Life’s Bias for Right-Handed DNA
Cosmic rays may have given right-handed genetic helixes an evolutionary edge at the beginning of life’s history.
The Cartoon Picture of Magnets That Has Transformed Science
One hundred years after it was proposed, the Ising model is used to understand everything from magnets to brains.
Growing Anomalies at the Large Hadron Collider Raise Hopes
Collider physicists report that several measurements of particles called B mesons deviate from predictions. Alone, each oddity looks like a fluke, but their collective drift is more suggestive.
What Goes On in a Proton? Quark Math Still Conflicts With Experiments.
Two ways of approximating the ultra-complicated math that governs quark particles have recently come into conflict, leaving physicists unsure what their decades-old theory predicts.
