No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...

The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find. When you purchase through links on our site, we may earn ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

Learn about the standard model of particle physics, the most accurate physical theory yet. Our laws of physics are equations of motion, along with some associated constants. We’ve talked about the ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

The atypical structure of the radium monofluoride molecule allows physicists to search for answers to some of the universe’s biggest questions.

Glenn Starkman receives funding from the Office of Science of the US Department of Energy. He is affiliated with Case Western Reserve University. The Standard Model. What a dull name for the most ...

Thirteen million light years away, a handful of relatively small galaxies revolve in a disk around the larger elliptical galaxy Centaurus A. There’s nothing unusual about a collection of small ...
