First Emergency Diesel Generator Successfully Introduced at Unit 6 of Lufeng Nuclear Power Plant

On September 4, 2026, the first emergency diesel generator for Unit 6 of Lufeng Nuclear Power Plant was successfully introduced into the diesel generator building. The emergency diesel generator is a critical required power source during the cold test phase of a nuclear power unit. The successful introduction of this equipment ensured the availability of emergency power during the cold test period, providing a solid power guarantee for the smooth execution of subsequent cold test work for Unit 6. The Installation Management Section of Lufeng Nuclear Power shifted from passive waiting to proactive action, planning the diesel generator introduction route in advance.

BESSY II reveals early-stage copper oxidation: providing evidence for catalyst development and corrosion research on nuclear waste final disposal containers

Germany's BESSY II synchrotron facility has recently provided new experimental insights into the early-stage oxidation process of copper surfaces. The study shows that before the formation of pure copper oxides, copper and oxygen atoms first form complex surface superstructures, such as "29"CuₓO. The chemical state of such structures has long been debated, and the findings are of reference value for catalyst research as well as for corrosion protection studies of copper containers used for radioactive waste final disposal. Before the formation of pure copper oxide, complex superstructures composed of copper and oxygen atoms emerge—such as "29"CuxO. HZB In everyday environments, copper surfaces gradually lose their red metallic luster and form a greenish oxide layer. This layer structure can slow further corrosion over an extended period. Regarding the initial stages of this process, the core question researchers focus on is: to what extent are copper atoms actually oxidized once oxygen enters the copper surface. Since conventional spectroscopic methods struggle to clearly distinguish between pure copper and partially oxidized surfaces, such oxidation states have previously been difficult to determine directly.

ORNL Neutron Imaging Technology Reveals Healed Rib Fracture in Tyrannosaurus Rex Fossil

Neutron imaging technology at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) has helped researchers from the University of Regina in Canada and other institutions observe rare healing signs inside the fossilized bones of a Tyrannosaurus rex, providing new insights into ancient life from approximately 66 million years ago. The subject of this study is a fractured rib from "Scotty," the largest Tyrannosaurus rex skeleton ever discovered. Researchers found that this rib preserved a wound-healing process rarely seen in the fossil record: after the fracture occurred, iron-rich blood entered the injured area and formed a network of blood vessels to promote healing; however, before the rib had fully healed, Scotty died and was preserved in a salt marsh environment, which slowed the decomposition of the remains...

"Wukong" Detects "Super-Iron" Elements in Cosmic Rays, Achieving First High-Precision Cosmic Ray Nickel Energy Spectrum in the TeV Range

Recently, the DAMPE scientific team led by Academician Chang Jin of the University of Science and Technology of China made significant progress in direct observations of high-energy cosmic rays. Based on DAMPE on-orbit observation data, the scientific team obtained the differential flux spectrum of nickel nuclei from 10 GeV/n to 2 TeV/n. The results were published in the international academic journal *Physical Review Letters* under the title "Measurement of the Cosmic Ray Nickel Energy Spectrum from 10 GeV/n to 2 TeV/n with the DAMPE Space Mission." The origin of super-iron elements in cosmic rays has long been a challenge for the scientific community. It is generally believed that cosmic ray elements are primarily produced in nuclear fusion processes within stars, but since iron nuclei have the highest binding energy per nucleon, stellar fusion reactions typically struggle to proceed beyond elements near iron. Heavier elements than iron are generally attributed to different nucleosynthesis processes such as neutron capture. Because the abundance of super-iron elements is typically at least an order of magnitude lower than that of iron, measurements of super-iron elements in cosmic rays remain extremely scarce. Most experiments have only provided relative abundances of different elements; a few experiments have measured the differential flux spectrum of cosmic ray nickel, but with energy upper limits of only a few hundred GeV/n.

Japanese Research Uses Tau PET to Reveal Association with Symptom Progression in Progressive Supranuclear Palsy

A research team at the National Institutes for Quantum Science and Technology (QST) in Japan recently announced findings from a study on progressive supranuclear palsy (PSP). Using their self-developed tau PET imaging technology, the researchers conducted follow-up scans on the same group of PSP patients at approximately one-year intervals, confirming for the first time in living brains that the faster tau protein accumulates in the globus pallidus region deep within the brain, the faster patient symptoms progress. The findings were published on September 5, 2026, in the international neurology journal *Movement Disorders*. Characteristic tau protein accumulation regions in PSP Progressive supranuclear palsy is a progressive neurodegenerative disease occurring in middle-aged and older adults, with common manifestations including increased risk of falls, difficulty with movement, eye movement disorders, postural instability, and cognitive dysfunction. There is currently no therapy that can cure or halt disease progression; therefore, establishing biomarkers that can objectively reflect disease changes and treatment efficacy has been a critical issue in drug development. Previous autopsy studies have shown that abnormal tau protein accumulation in the brains of PSP patients is an important pathological feature, particularly concentrated in deep brain regions such as the globus pallidus and midbrain. However, autopsy samples cannot be used for long-term dynamic observation, and how tau protein accumulation changes over time and how it corresponds to symptom progression had previously remained unclear. In recent years, positron emission tomography (PET) has made it possible to observe tau protein in living brains, but existing studies have mainly shown that tau protein increases over time without sufficiently demonstrating a direct association between these changes and symptom worsening. In this study, the research team used the PET radiopharmaceutical 18F-PM-PBB3 developed by QST, namely florzolotau (18F), to perform two PET examinations on 26 PSP patients and 10 healthy controls, conducted at baseline and approximately one year later. The researchers combined 57 brain regions identified by MRI and performed multivariate analysis of PET signal changes to identify PSP-related tau protein accumulation regions and their spread over time. The results showed that at baseline, tau protein in PSP patients was primarily accumulated in subcortical regions such as the globus pallidus and midbrain, consistent with previous reports. Follow-up imaging at one year showed further increases in tau protein accumulation in the globus pallidus, along with marked increases in tau accumulation in the frontoparietal lobes and cerebellar white matter, suggesting that during the course of PSP, tau protein may spread from deep brain regions to the cerebral cortex and cerebellar-related areas. The research team further focused on Richardson's syndrome, the most typical and common subtype of PSP. This subtype typically progresses rapidly, and the 18 patients with this subtype included in this study showed significant increases in PSP rating scale scores within one year. The analysis found that changes in tau protein accumulation in the globus pallidus showed the strongest correlation with the degree of symptom progression; that is, the faster tau protein accumulated in this region, the more pronounced the worsening of patient symptoms. Analyses of individual patients likewise showed that globus pallidus tau protein accumulation can reflect the course of PSP from mild to severe stages. The researchers believe that serial tau PET imaging has the potential to serve as a novel imaging biomarker for assessing PSP disease progression, and also provides a basis for tau-targeted therapeutic strategies: if future therapies can inhibit tau protein accumulation, it may be possible to slow symptom progression. Next steps still require longer-term follow-up in a larger number of patients to validate the relationship between changes in tau protein accumulation and overall symptom progression and treatment response. The imaging assessment method established in this study may not only be used for disease monitoring and clinical trial efficacy evaluation in PSP, but may also be extended to research on other tau protein-related neurodegenerative diseases and dementias, providing new technical support for the diagnosis and therapeutic development of related diseases.

No Evidence of Mirror Neutrons Found in Swiss PSI Ultracold Neutron Experiment

The Ultracold Neutron Physics Group at the Paul Scherrer Institute (PSI) in Switzerland recently stated that its research team found no evidence of spontaneous transformation of ordinary neutrons into mirror neutrons in a high-precision experiment. The researchers said the result essentially rules out the main parameter space previously suggested for anomalous neutron-mirror neutron oscillation signals, and also weakens the possibility that mirror neutrons could be a component of dark matter. Bernhard Lauss (left) and Géza Zsigmond examined approximately 2.5 billion neutrons at the ultracold neutron source at the Paul Scherrer Institute (PSI). They essentially ruled out the hypothesis of spontaneous transformation of neutrons into mirror neutrons. (Image courtesy of Paul Scherrer Institute PSI/Ma...
