UK's MAST Upgrade sets plasma pressure record in fifth experimental campaign

The UK Atomic Energy Authority (UKAEA) has completed the fifth experimental campaign of its flagship fusion experiment, MAST Upgrade. The campaign, conducted between 2025 and 2026 at the Culham Campus in Oxfordshire, UK, produced over 1,100 plasma pulses and achieved the device's highest-ever plasma pressure while overcoming plasma instability issues. In fusion devices, hydrogen isotopes must be heated, compressed, and confined under extremely high temperatures and pressures. The higher the plasma density and temperature, the stronger the fusion reaction, and high-pressure plasmas are also closer to the operating conditions required for future commercial fusion power plants.

Recently, the research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with collaborators, successfully produced and identified the rare isotope hafnium-153 using the High-Intensity Heavy-Ion Accelerator Facility (HIAF). This is the first physics result obtained during the commissioning of HIAF, demonstrating that China's new-generation high-intensity heavy-ion research facility is capable of exploring unknown nuclides and expanding the nuclear chart. It marks the official commencement of HIAF's scientific discovery journey. The result was published as a short communication in *Science Bulletin*. Figure: Position of hafnium-153 on the nuclear chart; the blue line indicates the boundary of known nuclides. Image | Hu Houyu, Li Hongfu. Atomic nuclei are composed of protons and neutrons, and different combinations of proton and neutron numbers form the diverse world of nuclides. Exploring unknown nuclides and investigating the boundaries of nuclear existence are important frontiers in nuclear physics. Hafnium-153 is located in the neutron-deficient heavy-mass region and is an important subject for studying the evolution of nuclear structure and the limits of nuclear stability. It had not been reported prior to this experiment. The discovery and precise measurement of this nuclide will help test nuclear theory models and deepen our understanding of nuclear structure regularities.

After 25 Years, the Muon Wobble Puzzle Sees Key New Progress in Physics

For 25 years, precise measurements of how muons wobble in a magnetic field have been a major puzzle in particle physics. Early experiments showed a discrepancy between the measured value of the muon's g-factor and theoretical predictions, a difference once seen as a possible hint of unknown particles. Recent new theoretical calculations and experimental analyses have brought a new twist to this puzzle. The muon is a heavier cousin of the electron that precesses like a tiny magnet in a magnetic field. Its extra wobble is quantified by the muon g-2 coefficient. According to quantum theory, known particles and interactions influence this coefficient through fleeting quantum fluctuations, making muon g-2 a key test of the Standard Model...

Swiss PSI Ultracold Neutron Experiment Finds No Signs of "Mirror World" Oscillation

The Paul Scherrer Institute (PSI) in Switzerland announced on July 28 that its researchers detected approximately 25 billion neutrons in an ultracold neutron experiment and found no signs of neutrons spontaneously transforming into mirror neutrons. The results constrain, with high certainty, the theoretical possibility of neutrons disappearing into the so-called mirror world. The mirror world hypothesis posits that every elementary particle in the real world may have a corresponding mirror particle, such as mirror electrons, mirror protons, and mirror neutrons. Such particles interact extremely weakly with ordinary matter, potentially connecting primarily through gravity or rare oscillations of neutral particles, and have therefore also been considered as dark matter candidates...
