NMR Reveals Thermal Self-Organization in Resistive Switching of Organic Conductor by Japanese Team

A joint research team from Tokyo University of Science, the National Institute for Materials Science, and RIKEN in Japan recently used bulk-sensitive ¹H-NMR measurements to reveal the internal electronic state of the organic conductor (d7-DMe-DCNQI)2Cu during resistive switching. The study found that, in the switching state, the material does not form a uniform new electronic phase, but rather a coexistence of metallic and insulating phases within the material. Schematic of bulk-crystal ¹H-NMR measurements Resistive switching refers to the phenomenon in which a material's resistance changes significantly under an applied current or voltage, and has attracted attention in research on correlated electron systems, memory devices, and neuromorphic devices. Previous studies have mostly...

Japan Atomic Energy Agency discovers magnetic "strong-weak waves" in uranium semiconductor

The Japan Atomic Energy Agency announced on August 21 that its research team has discovered a special magnetic structure in the layered uranium semiconductor α-UTe3 (α-uranium tritelluride): the magnetism of uranium atoms not only alternates in opposite directions, but its magnetization intensity also periodically strengthens and weakens depending on the crystal position, forming a state resembling “strong-weak waves.” α-UTe3 is composed of uranium and tellurium atoms and belongs to van der Waals layered materials, where atomic layers are stacked through weak interlayer forces. Using high-quality α-UTe3 single crystals, the research team analyzed its low-temperature magnetic structure through resistivity, specific heat, and magnetization measurements, as well as nuclear magnetic resonance and single-crystal neutron diffraction techniques...

Japan's J-PARC Uses Negative Muon Non-Destructive Analysis to Reveal Gold-Rich Surface Structure of Nagoya Castle's Golden Shachi Scales

A joint research team comprising the High Energy Accelerator Research Organization (KEK), the J-PARC Center, the Nagoya Castle Research Center, and the National Museum of Nature and Science, among others, used the negative muon beam at the J-PARC Materials and Life Science Experimental Facility (MLF) to conduct non-destructive depth analysis on seven surviving scales of the golden shachi (ornamental dolphin-tiger fish) on Nagoya Castle's keep, confirming that five of the scales have a layered structure with high gold content within approximately 10 micrometers of the surface. The golden shachi on Nagoya Castle's keep was largely destroyed in the air raids of 1945, with some scales rescued and preserved to this day. Previously, researchers had examined these scales using X-ray fluorescence analysis, but the results showed that some scales with a bright golden appearance did not necessarily have a high average gold content.

Russian Research Team Proposes New Method for Measuring Proton and Deuteron Electric Dipole Moments in a Single Storage Ring

Physicists from several Russian research institutions have proposed a new method for searching for the electric dipole moments of protons and deuterons, potentially enabling the study of both particle types in a single storage ring. The participating institutions include the Moscow Institute of Physics and Technology, the Institute for Nuclear Research of the Russian Academy of Sciences, the National Research Nuclear University MEPhI, and the Landau Institute for Theoretical Physics of the Russian Academy of Sciences. The research was published in the journal *Nuclear Science and Technology* and was supported by a grant from the Russian Science Foundation. The electric dipole moment reflects whether there is a tiny asymmetry between the internal charge distribution of a particle and its spin direction. According to Standard Model predictions, the electric dipole moments of the proton and deuteron are nonzero but extremely small, on the order of 10...

U.S. Electron-Ion Collider ePIC Detector Completes First Batch of Lead Tungstate Crystal Procurement and Acceptance

The U.S. Electron-Ion Collider (EIC) project recently achieved its first long-lead procurement milestone: 1,069 custom lead tungstate crystals for the new ePIC detector have been delivered, tested, and accepted. These crystals will be used in the Electron Endcap Electromagnetic Calorimeter (EEEMCAL) to help precisely measure the energy of scattered electrons during collisions. The EIC is being built by the U.S. Department of Energy's Brookhaven National Laboratory, in collaboration with the Thomas Jefferson National Accelerator Facility. The facility will circulate electron and ion beams in opposite directions, colliding them inside the ePIC detector. The ePIC detector records information about particles produced in the collisions, providing data for studying the fundamental constituents of visible matter...

German Team Achieves Ultrafast Shaping of Extreme Ultraviolet Pulses Using High-Density Helium Gas

August 20, 2026, the international team led by researchers from the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg announced that they have utilized atomic gas as a rapidly switchable time-varying lens to control the beam shape and spectrum of intense high-frequency laser pulses. This achievement is expected to provide a new pathway for the fine control of extreme ultraviolet (XUV) and X-ray pulses, and may serve research directions such as improved spectroscopic methods, control of chemical reactions, and quantum computing. Extreme ultraviolet light can provide important tools for studying atomic-scale processes. With the development of free-electron lasers, researchers have been able to generate ultrashort, high-intensity XUV light pulses, but how to manipulate them like...

Finland's 2025 Environmental Radiation Monitoring Shows No Harmful Effects from Nuclear Power Plant Operations

The 2025 environmental radiation monitoring results released recently by the Radiation and Nuclear Safety Authority of Finland (STUK) show that radioactive substance levels in the Finnish environment generally remained low, and the operation of the Loviisa and Olkiluoto nuclear power plants has not caused harmful radiation impacts on the public or the environment. STUK continuously tracks Finland's radiation situation through its environmental radiation monitoring program. The monitoring includes continuous measurement of external radiation, as well as monitoring of radioactive substances in air, radioactive fallout, water bodies, food, and the human body, with the aim of promptly detecting changes in radiation levels and confirming the safety of the living environment. Finland's automatic external radiation monitoring network covers essentially the entire country. In 2025, 255 monitoring...

Japan Plans to Include Hitachiomiya, Ibaraki Prefecture, in Nuclear Waste Disposal Site Selection Survey

According to sources familiar with the matter on August 31, Japan's Ministry of Economy, Trade and Industry is considering conducting a preliminary survey in Hitachiomiya, Ibaraki Prefecture, to designate the city as one of the potential candidate sites for a final disposal facility for high-level radioactive waste. The relevant plan is expected to be submitted to the Hitachiomiya municipal government. If the local government accepts the plan, Hitachiomiya will become the fifth location in Japan to undergo such a preliminary survey. The site selection process for Japan's high-level radioactive waste disposal facility involves multiple stages, and the entire screening process typically takes several years. The proposed preliminary survey is an early step to determine whether the area meets the conditions for further evaluation...
