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...

German Science and Humanities Council Supports German Participation in the LEGEND-1000 Neutrinoless Double Beta Decay Experiment

On July 27, 2026, the German Science and Humanities Council expressed its support for German participation in the LEGEND-1000 experiment. The project had previously passed scientific evaluation and was deemed significant for a broad research community in the fields of particle physics and nuclear physics. LEGEND-1000 is the next phase of the large-scale enriched germanium neutrinoless double β decay experiment, planned to be constructed by an international collaborative team at the underground laboratory of the Gran Sasso National Laboratory in Italy. German participating institutions include the Max Planck Institute for Nuclear Physics in Heidelberg and the Technical University of Munich, with project leaders being Professor Susanne Mertens and Professor Stefan Schönert, respectively. According to the project...

Japan aims to rebuild up to 5 retired nuclear power plants by the 2040s

The Japanese government held a ministerial meeting on nuclear power on July 31 and decided to rebuild up to 5 retired nuclear power plants by the 2040s. This is the first time since the Fukushima Daiichi nuclear accident that the Japanese government has set a specific numerical target for nuclear plant reconstruction. Kansai Electric Power Company's Mihama Nuclear Power Plant Japanese Prime Minister Takaichi Sanae stated at the meeting that to steadily advance nuclear power investment, the Takaichi cabinet will continue to promote nuclear energy policy. According to the direction set at the meeting, Japan plans to rebuild 2 to 5 nuclear power plants by the 2040s, with a total installed capacity of approximately 2.2 million to 5.5 million kilowatts; by the 2050s, the reconstruction scale will expand to 11 to 14 plants, with a total installed capacity of approximately 12.7 million to 16 million kilowatts. The Japanese government plans to...

Russian researchers detect anomalous signs in bottomonium states using Belle II experiment data

The Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences recently announced that Russian researchers have detected anomalous phenomena in the analysis of data from the international Belle II experiment, indicating that the structure of certain excited states of bottomonium may be more complex than predicted by traditional models. Bottomonium is a class of unstable heavy particles composed of a bottom quark and an anti-bottom quark. Yevgeny Kovalenko, a young researcher at the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences, stated that analysis of Belle II experiment data suggests that certain excited states of bottomonium may contain lighter quark components. In other words, these particles in specific states may not simply be plain bottom quark–anti-bottom quark combinations.

Princeton University and PPPL Launch Collaborative Graduate Program in Plasma Science and Technology

The Princeton Plasma Physics Laboratory (PPPL), a U.S. Department of Energy (DOE) facility, and Princeton University recently launched the Collaborative Research Program in Plasma Science and Technology (CRPST). This two-year program, which began on July 1, 2026, aims to establish a more formal joint mentorship mechanism and expand opportunities for Princeton University graduate students in engineering, physics, and related disciplines to participate in research at PPPL. Under the program, selected students will be jointly mentored by a PPPL scientist and a Princeton University faculty member. Students will work at PPPL at least one day per week, participate in relevant research groups, and use laboratory facilities to advance their projects...
