The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Doug Cowen is a professor of astronomy, astrophysics and physics at Pennsylvania State University; Derek Fox is an associate professor of astronomy and astrophysics at Pennsylvania State University; ...

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.

Eight decades after one of the weirdest discoveries in the history of science -- that subatomic matter is wavelike -- Austrian scientists are studying the same phenomenon on a much bigger scale, in ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...

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, ...

As the nucleus splits, it also releases its neutrons. These neutrons bounce around at incredible speeds until some eventually ...

CERN, the world’s largest atom smasher, says it has observed three new "exotic particles" while carrying out its third run of collisions. After a three-year pause for maintenance and routine checks, ...

Being able to precisely locate individual nanoparticles in a device is no easy task but it is important for many research fields, including nanometrology, medicine and biophysics. A team of scientists ...

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 ...

The quantum world is a pretty wild one, where the seemingly impossible happens all the time: Teensy objects separated by miles are tied to one another, and particles can even be in two places at once.
