To probe the "knee" more precisely, scientists need to measure the energy spectra of individual types of cosmic rays, such as protons, helium and heavier nuclei. But cosmic rays in this energy range ...

Scientists develop a microscopic heat engine that achieves 100% efficiency, accomplishing what seemed impossible.

Humanity has achieved remarkable feats, yet 95% of the universe remains invisible and unexplained. Our theories, general ...

Chris Neu studies dark matter at the Large Hadron Collider, bringing big ideas to his classroom and students into his lab.

In this episode we explore the Deep Underground Neutrino Experiment, a decades-long effort to build the most ambitious ...

ABSTRACT: The Daya Bay Collaboration has discovered that approximately 6.0% of active neutrinos were missing from the nuclear reaction container. This finding has led to a reinterpretation of the ...

This repository consolidates key derivations, simulations, and predictions regarding the Geometrodynamics of Entropy (GdE) theory. GdE proposes a unification of physics based on a (3+3) spacetime, ...

CERN’s Super Proton Synchrotron will turn 50 in 2026—and it has a resonant “ghost.” Using mathematics, physicists measured and modeled how these resonant lines intersect. Modeling a 3D shape over time ...

Here’s what you’ll learn when you read this story: For nearly a century, the magnetic anomaly of the fundamental particle known as a muon has served as a means to test theories against experimental ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...
