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.

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Physicists at the world’s largest atom collider have observed three new exotic particles as they continue to search for clues about the mysterious forces that bind subatomic particles together, they ...

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.

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 ...
