Add Yahoo as a preferred source to see more of our stories on Google. The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and ...

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a test, but rather the physical stresses that affect everyday objects.

They say you can never trust an atom because they make up everything. This week, we’re shrinking down and getting literally into the heart of the matter. We’ve covered the periodic table and all its ...

The scientific world has long known that atoms form the basic building blocks of matter, but CERN is interested in peering beyond the atom into the mesonic and baryonic soup that gives rise to matter ...

A new study shows, for the first time, an experiment that could detect a class of ultra-high-energy neutrinos using radar echoes. One of the greatest mysteries in astrophysics these days is a tiny ...

To peer into the heart of the sun, a 13.7-meter-wide stainless steel shell lined with over 2,200 light-gathering sensors hides deep under a mountain in central Italy. Known as the Borexino experiment, ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

Quantum chromodynamics, or QCD, is the theory of the strong interaction between quarks and gluons. Lattice QCD uses supercomputers to explore 'tantalizing hints' of new physics in discrepancies ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

In 2015, the world's most powerful atom smasher, the Large Hadron Collider, will restart. The particle accelerator has already discovered the Higgs boson, the so-called "God particle," and when it ...
