International Researchers Successfully Develop the First Autonomous Thorium-229 "Nuclear Clock": Featuring Ultra-Strong Interference Resistance and a Fully Autonomous Closed-Loop Stable Operation Mechanism

Recently, the press office of TU Wien (Vienna University of Technology) announced that a team of scientists from Austria, Germany, and the Czech Republic has successfully developed the world's first nuclear clock based on the thorium-229 (chemical symbol ²²⁹Th) atomic nucleus. This nuclear clock possesses extremely high interference resistance and is capable of operating in a fully autonomous mode without external stabilization. The research team stated that, compared with traditional atomic clocks that operate using entire atoms, timekeeping using atomic nuclei can theoretically achieve higher measurement precision. Two years ago, they successfully controlled the transition process of the thorium-229 atomic nucleus for the first time, but to achieve extremely high-precision timekeeping, it was still necessary to solve the nuclear clock...

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.

U.S. Research Reveals Diamond Melting Mechanism at High Pressure, Potentially Enhancing Inertial Confinement Fusion Performance

A research team at Lawrence Livermore National Laboratory (LLNL) in the U.S. recently published a study in Nature Physics reporting that the latest dynamic compression experiments have, for the first time, directly recorded atomic structural changes during diamond melting under extreme high pressure. The experiments showed that under high-pressure conditions, solid diamond can float in liquid metallic carbon, similar to ice floating on water. Diamond is not only a high-hardness carbon material but is also used as the fuel target capsule shell in inertial confinement fusion experiments. When intense lasers drive the capsule implosion, the compression and melting behavior of the diamond shell can affect whether the fusion fuel reaches the required high-temperature, high-pressure state. Meanwhile, the planetary science community has long focused on the high-pressure behavior of carbon in the deep interiors of ice giant planets...

Korea's Gil Medical Center Expands Application of Markerless Surface-Guided Radiation Therapy

Gachon University Gil Medical Center in South Korea announced on August 26 that it is expanding the clinical application of markerless surface-guided radiation therapy (SGRT) to enhance the precision and comfort of radiation therapy for cancer patients. According to the hospital, the proportion of markerless SGRT in its radiation therapy procedures has increased from 28% in the first half of 2025 to 37% in the first half of 2026. This change indicates that this treatment-assistive technology, which reduces the burden of skin marking on patients, is gaining broader clinical adoption. Markerless SGRT is an advanced technique used for patient positioning and monitoring during radiation therapy. Unlike conventional methods, patients do not need to retain target line markings on their skin; the treatment system can assist in confirming patient positioning through surface guidance, enabling radiation to be delivered more accurately to the target area.
