Parity violation in neutron physics represents a subtle but fundamentally important deviation from mirror symmetry in nuclear interactions. This phenomenon arises from the interplay between the weak ...

After more than 25 years of experience in condensed matter physics, as a student, researcher and in high-ranking executive ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a few ...

Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists. Neutron star mergers are a treasure trove ...

On 13 September 2025, 40 researchers came together at the Paul Scherrer Institute (PSI) to discuss the neutron-lifetime ...

In this video I show you what happens when you try to get close to 1 drop of a neutron star. I tell you how a neutron star is made and then also talk about different types of stars and show you a ...

One of the most important experiments of quantum physics gets a makeover: When neutrons are fired at a crystal, they can be made to travel along two paths at the same time. Until now, this was only ...

Testing basic principles of particle physics does not necessarily require a high-energy accelerator. As Peter Geltenbort explains, a growing community of neutron scientists is probing similarly ...
