China Becomes First to Achieve Operation of a Thorium-229 Nuclear Optical Clock, Bringing Quantum Precision Measurement into the Atomic Nucleus Scale

Recently, the team of Ding Shiqian, associate professor in the Department of Physics at Tsinghua University, published important results online in the international academic journal Nature, announcing the successful development of a thorium-229 nuclear optical clock and the achievement of its stable operation. This work was completed independently in the same period as that of a European team, making China the first internationally to achieve operation of a thorium-229 nuclear optical clock, marking the successful extension of the time measurement standard from electronic transitions to nuclear transitions. It is understood that a nuclear optical clock uses the internal transition of the thorium-229 atomic nucleus as a time-frequency reference. Ding Shiqian, one of the corresponding authors of the paper, introduced that the pendulum of an old-fashioned wall clock swings about once per second, whereas a nuclear optical clock uses the beat of the atomic nucleus as its "pendulum," with a beat frequency of up to about 2 quadrillion times per second. Because the size of the atomic nucleus is only a few tens of thousandths of the electron cloud outside the nucleus...

FDA Approves Telix's New Brain Tumor Imaging Agent Pixclara

The U.S. Food and Drug Administration (FDA) has approved a new brain tumor imaging agent developed by Australian pharmaceutical company Telix, the company announced on Monday. The product, called Pixclara, is a radioactive diagnostic drug used in combination with positron emission tomography (PET) imaging. Its primary use is to help doctors distinguish between recurrent brain tumors and harmless changes caused by prior treatment. The FDA approval comes after Telix faced an FDA rejection last year due to insufficient evidence. Kevin Richardson, CEO of Telix Precision Medicine, said in a statement: "As the first FDA-approved PET imaging drug for glioma (a type of brain tumor), Pixclara will provide physicians in the United States with more definitive diagnoses and greater confidence in patient treatment planning."

Fudan team extracts CKM matrix element |Vus| via quantum entanglement in collider experiment for the first time

On the evening of September 2, 2026, Beijing time, the team led by Luo Tao from the Institute of Modern Physics at Fudan University, together with collaborators, published a research achievement titled "Exploring baryon semileptonic decays through polarization and entanglement" in Nature. This study, for the first time in a collider experiment, utilized quantum entanglement and polarization information to extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |Vus|, providing a new experimental pathway for precisely testing the Standard Model of particle physics. The CKM matrix describes the strength of transitions between different quarks under the weak interaction. Among them, |Vus| corresponds to the transition from the strange quark to the up quark, and its numerical precision is related to the test of the three-generation quark mixing mechanism in the Standard Model. Currently, results for |Vus| obtained from different decay processes still show discrepancies, and the unitarity test of the first row of the CKM matrix also exhibits some tension, necessitating more independent measurement methods for verification.

U.S. Heavy-Ion Collision Research Suggests Protons and Neutrons May Not Be Just "Three Quarks"

The STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy's Brookhaven National Laboratory recently proposed, based on heavy-ion collision data studies, that baryons such as protons and neutrons may not be simply composed of three valence quarks, and that their baryon number may be more closely related to "baryon junctions" in the gluon field. The findings were published in the journal *Science*. In the traditional valence quark model, each quark is assigned a baryon number of 1/3, so baryons such as protons and neutrons, composed of three quarks, carry a baryon number of +1. However, this model is not a fundamental requirement of quantum chromodynamics (QCD). As early as the 1970s, alternative explanations had been proposed in the theoretical community; in 1996, Dmitri Kharzeev proposed a model suggesting that the baryon number is not necessarily carried by the quarks themselves, but may instead be concentrated at the Y-shaped junction formed by the gluon field—the "baryon junction."

Japan's PF Launches Quantum Multi-Beam Experiments, Achieving Simultaneous Hard and Soft X-ray Measurements

The Photon Factory, a synchrotron radiation facility at the Institute of Materials Structure Science, High Energy Accelerator Research Organization (KEK) in Japan, has recently launched collaborative experiments on the development and research multi-purpose beamlines BL-11A and BL-11B, achieving simultaneous irradiation of the same sample with hard and soft X-rays at the same position. The research results will be published in the international academic journal *Review of Scientific Instruments*. The Photon Factory uses electrons moving at near-light speed to generate high-brightness X-rays, known as synchrotron radiation, for studying material structures and properties. Among these, hard X-rays are better suited for observing the internal structure of materials, while soft X-rays are ideal for analyzing material surfaces and electronic states. Previously, at synchrotron radiation facilities, the two types of X-rays typically had to...

U.S. STREAMLINE Project Advances Nuclear Quantum Many-Body Research with Artificial Intelligence

On August 25, 2026, a new project named STREAMLINE is combining artificial intelligence, machine learning, and supercomputing to address the nuclear quantum many-body problem in nuclear physics research, aiming to more accurately simulate the interactions between protons and neutrons within atomic nuclei and provide theoretical support for frontier topics such as neutron stars and fundamental interactions. The difficulty of the nuclear quantum many-body problem lies in the fact that as the number of particles increases, the possible interactions among them grow rapidly, and traditional computational methods quickly hit the ceiling of computing power. Even with high-performance supercomputers, only quantum systems of relatively limited scale can typically be handled. The STREAMLINE project hopes to...
