By studying neutron ‘starquakes,’ scientists hope to transform their understanding of nuclear matter

The study of ‘starquakes’ (like earthquakes, but in stars) promises to give us important new insights into the properties of neutron stars (the collapsed remnants of massive stars), according to new research led by the University of Bath in the UK.

Such explorations have the potential to challenge our current approaches to studying , with important impacts for the future of both nuclear physics and astronomy. Longer term, there may also be implications in the fields of health, security and energy.

The value of studying asteroseismology—as these vibrations and flares are known—has emerged from research carried out by an international team of physicists that includes Dr. David Tsang and Dr. Duncan Neill from the Department of Physics at Bath, along with colleagues from Texas A&M and the University of Ohio.

Neutron isotropy measurements validate sheared-flow-stabilized Z pinches for stable thermal fusion

In physics, the term “isotropy” means a system where the properties are the same in all directions. For fusion, neutron energy isotropy is an important measurement that analyzes the streams of neutrons coming from the device and how uniform they are. This is critical because so-called isotropic fusion plasmas suggest a stable, thermal plasma that can be scaled to higher fusion energy gains, whereas anisotropic plasmas, those emitting irregular neutron energies, can lead to a dead end.

A new Zap research paper, published in Nuclear Fusion, details neutron isotropy measurements from the FuZE that provide the best validation yet that Zap’s sheared-flow-stabilized Z pinches generate stable, thermal . It’s a benchmark milestone for scaling fusion to higher energy yields in Zap’s technology and giving confidence in reaching higher performance on the FuZE-Q device.

“Essentially, this measurement indicates that the is in a ,” says Uri Shumlak, Zap’s Chief Scientist and Co-Founder. “That means we can double the size of the plasma and expect the same sort of equilibrium to exist.”

OpenAI partners with U.S. National Laboratories on scientific research, nuclear weapons security

OpenAI on Thursday said the U.S. National Laboratories will be using its latest artificial intelligence models for scientific research and nuclear weapons security.

Under the agreement, up to 15,000 scientists working at the National Laboratories may be able to access OpenAI’s reasoning-focused o1 series. OpenAI will also work with Microsoft, its lead investor, to deploy one of its models on Venado, the supercomputer at Los Alamos National Laboratory, according to a release. Venado is powered by technology from Nvidia and Hewlett-Packard Enterprise.

NEON experiment shares results from first direct search for light dark matter

Detecting dark matter, the elusive type of matter predicted to account for most of the universe’s mass, has so far proved to be very challenging. While physicists have not yet been able to determine what exactly this matter consists of, various large-scale experiments worldwide have been trying to detect different theoretical dark matter particles.

One of these candidates is so-called light dark matter (LDM), particles with low masses below a few giga-electron volts (GeV/c2). Theories suggest that these particles could weakly interact with ordinary matter, yet the weakness of these interactions could make them difficult to detect.

The NEON (Neutrino Elastic Scattering Observation with Nal) collaboration, a group of researchers analyzing data collected by the NEON detector at the Hanbit nuclear reactor in South Korea, have published the results of their first direct search for LDM.

An overlooked nuclear force helps keep matter stable, study reveals

Researchers from Kyushu University, Japan have revealed how a special type of force within an atom’s nucleus, known as the three-nucleon force, impacts nuclear stability. The study, published in Physics Letters B, provides insight into why certain nuclei are more stable than others and may help explain astrophysical processes, such as the formation of heavy elements within stars.

All matter is made of atoms, the building blocks of the universe. Most of an atom’s mass is packed into its tiny , which contains protons and neutrons (known collectively as nucleons). Understanding how these nucleons interact to keep the nucleus stable and in a low energy state has been a central question in for over a century.

The most powerful nuclear force is the two– force, which attracts two nucleons at long range to pull them together and repels at short range to stop the nucleons from getting too close.
