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 ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide. Physics fans, are you ready to ...

Snappily named Xi-cc-plus, Cern physicists spotted the particle in shower of debris that lit up Large Hadron Collider ...

Matter is a lush tapestry, woven from a complex assortment of threads. Diverse subatomic particles weave together to fabricate the universe we inhabit. But a century ago, people believed that matter ...

The stuff you scrape off burnt toast is made primarily of atoms of carbon. But what makes up a carbon atom—or any other atom? The first subatomic particle to be identified was the electron, in 1898.

A new study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as ...

In Bernard Malamud’s The Natural, Iris (played in the movie version by Glenn Close) tells Roy Hobbs that we all have two lives, “the life we learn with and the life we live with after that.” Murray ...

The protons and neutrons that build the nucleus of the atom frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how packed ...

Physicists are drawing closer to answering a long-standing mystery of the Universe: how long a neutron lives. Neutrons are electrically neutral particles that usually combine with protons to make up ...

At Oak Ridge National Laboratory in eastern Tennessee, physicist Leah Broussard is trying to open a portal to a parallel universe. She calls it an “oscillation” that would lead her to “mirror matter,” ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

An ancient crocodile’s last meal might never have come to light were it not for researchers deciding to scan the rock-embedded fossil with a beam of neutrons. The scientists had set out to see if ...
