At the American Society for Radiation Oncology annual meeting, phase 3 clinical results were announced: SBRT radiotherapy for localized prostate cancer achieves long-term control rates comparable to radical prostatectomy and greatly reduces the risk of incontinence.

A latest phase 3 randomized controlled clinical study announced at the American Society for Radiation Oncology (ASTRO) annual meeting shows that for patients with localized prostate cancer (PCa), stereotactic body radiotherapy (SBRT) demonstrates excellent clinical application potential. Follow-up data show that SBRT is comparable to traditional radical prostatectomy in 8-year biochemical or clinical failure-free rates, and the incidence of urinary incontinence at 5 years after treatment is significantly reduced by nearly 40%.

Major Scientific Facility Enables Breakthrough in New Energy Materials: IHEP Leverages Beijing Synchrotron Radiation Facility to Reveal High-Efficiency Crystallization Mechanism of Perovskite, Sub-module Photoelectric Conversion Efficiency Reaches 22.9%

Recently, the research team at the Multidisciplinary Research Center of the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences, has made important progress in the study of the microscopic mechanisms of perovskite solar cell materials. The research team innovatively introduced Prussian Blue (PB) nanoframes with a high degree of lattice matching to perovskite, and leveraged a national major scientific and technological infrastructure——the Beijing Synchrotron Radiation Facility (BSRF)——to conduct multi-dimensional in-situ synchrotron radiation characterization. From the two perspectives of transient crystallization kinetics evolution and microscopic local coordination structure, they systematically elucidated for the first time the physicochemical mechanism by which Prussian Blue regulates perovskite nucleation and crystallization and suppresses ion migration. Large-area perovskite photovoltaic modules fabricated via wet...

Türkiye Leverages Nuclear Science and Technology to Safeguard Citrus Productivity: Insect Sterile Technique and Radiation Mutation Breeding Build a Green Barrier for Agriculture

Türkiye produces approximately 5 million tonnes of various citrus fruits annually, covering major categories such as sweet oranges, lemons, and grapefruits, making it an important fruit exporter globally. However, the frequent occurrence of abnormal climate events such as extreme heat and cold waves with frost, combined with repeated infestations by persistent pests like fruit flies, has not only severely constrained crop yields and fruit quality but also posed severe challenges to the livelihoods of local farmers. To break through cultivation bottlenecks and meet the stringent requirements of international markets for fruit products with low pesticide residues, Türkiye, with technical support from the International Atomic Energy Agency (IAEA) and the Food and Agriculture Organization of the United Nations (FAO), has comprehensively introduced nuclear science and technology to build a green and sustainable integrated pest management...

Langfang Holds 2026 Unscripted Radiation Accident Realistic Emergency Exercise

On September 22, the Ecology and Environment Bureau of Langfang City, Hebei Province, together with the Guangyang District People's Government of Langfang City, held the 2026 unscripted radiation accident realistic emergency exercise at a nuclear technology utilization unit within its jurisdiction. This exercise resolutely rejected formalism, adopting throughout a double-blind mechanism with no preset script and no prior rehearsal, strictly following the basic principles of being unscripted, realistic, and based on Beijing-Tianjin-Hebei joint prevention and control, comprehensively testing extreme response and handling capabilities under sudden nuclear and radiation safety incidents. The exercise simulated a general radiation accident, with the scenario set as a nuclear technology utilization unit within the jurisdiction discovering during an inventory check that one Category IV radioactive source and one Category V radioactive source had been accidentally lost. After the dangerous situation occurred...
