Radioactive liquid waste leak suspected at QST's underground facility in Chiba due to record rainfall

According to Japanese media reports, due to record-breaking rainfall in Chiba Prefecture, an underground facility of the National Institutes for Quantum Science and Technology (QST) in Chiba City was flooded, and radioactive liquid waste in underground storage tanks at the facility may have mixed with rainwater and leaked outdoors. QST stated that as of the 13th, an estimated 2,000 to 3,000 liters of liquid waste had accumulated in the relevant underground storage tanks. After investigating water bodies around the tanks, the institute confirmed that detected radioactive material concentrations were below standard values, and no environmental impact has been indicated so far. QST reported the incident to national and local governments the following day and plans to submit preventive measures to the Nuclear Regulation Authority of Japan.

Fermilab Muon g-2 Experiment Sets New Direct Detection Limit on Muon Electric Dipole Moment

On August 12, 2026, the Muon g-2 Collaboration announced that a new analysis based on 25% of the data from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory has produced the most sensitive direct measurement of the muon's electric dipole moment to date. The results show that if a muon electric dipole moment exists, its magnitude is below the current detection threshold of the experiment. The muon electric dipole moment values measured by Fermilab across different data-taking periods were compared with previous results from Brookhaven National Laboratory. The combined Fermilab value is consistent with zero (no observation). Although the experiment uses positive muons, results are typically reported for negative muons, which reverses the sign of the measured value...

Argonne National Laboratory Unveils DONUT Tool to Accelerate Real-Time Analysis of X-ray Nanodiffraction Data

Researchers at the U.S. Department of Energy's Argonne National Laboratory have developed a new machine learning tool called DONUT to accelerate X-ray data analysis in experiments at the Advanced Photon Source (APS). The tool can process complex images generated by scanning X-ray nanodiffraction microscopy (SXDM) in real time during experiments, helping researchers more quickly determine internal structural changes in materials. DONUT stands for "Nanobeam Optical Diffraction based on Unsupervised Training," a physics-aware neural network. Its key feature is combining artificial intelligence methods with physical models of focused X-ray beam interactions with materials, allowing it to learn directly from experimental data without relying on pre-labeled training...

FDG PET/CT Enables More Precise Identification of Multiorgan Involvement in Brazilian Paracoccidioidomycosis

A study conducted by researchers at the Brazilian CEPID CancerThera center shows that molecular imaging with fluorodeoxyglucose (FDG) PET/CT can detect systemic lesions of paracoccidioidomycosis (PCM) more sensitively than conventional staging methods, helping to reassess the extent and severity of the disease. The findings were published in Clinical Infectious Diseases. Paracoccidioidomycosis is a systemic fungal disease caused by inhalation of fungal spores of the Paracoccidioides genus, with significant clinical and epidemiological importance in Brazil. Often referred to as "coffee planter's disease," it primarily affects the lungs but can also spread to multiple organs via lymphatic and hematogenous routes. Conventional staging typically relies on...
