Join six leading experts to find out everything we know about the subatomic universe. Take a deep dive into the building ...

A compact method of detecting neutrinos provides new tests of physics theories and could lead to new reactor-monitoring methods.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

A long-awaited calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility of new physics beyond the Standard Model ...

While this is below the 5σ level that is generally accepted as a discovery in particle physics, the observation is in line with the Standard Model of particle physics. The detection therefore helps ...

Operator Greetings, and welcome to the Microsoft fiscal year 2025 second-quarter earnings conference call. At this time, all ...

Magnetic monopoles are hypothetical particles that would carry magnetic charge, a concept first proposed by Paul Dirac in ...

In their new book, From Spinors to Supersymmetry, Herbi Dreiner, Howard Haber and Stephen Martin describe the two-component ...

Nuclear clocks would also be much more sensitive to new physics beyond the Standard Model – allowing physicists to explore hypothetical concepts such as dark matter. “The nuclear energy scale is ...
