Fusion for Energy completes full delivery of ITER cryopump distribution system

The International Thermonuclear Experimental Reactor (ITER) will operate in an ultra-high vacuum environment. To prevent contamination inside the device, a set of cryopumps supplied by Europe will extract gas particles and alternate operation before and after plasma discharges, maintaining the vacuum vessel pressure at approximately one millionth of Earth's atmospheric pressure. The core of cryopump operation lies in the extremely low-temperature environment. Its internal panels will be cooled to 4 K, approximately minus 269 degrees Celsius, close to absolute zero, to capture gas particles; they are then warmed to release and expel the particles. To precisely control this process, Europe is also supplying ITER with the Front-End Cryopump Distribution System (FECDS), which delivers helium at specific doses and temperatures to the cryopumps...

Chinese Team Proposes "Toxic Blood Meal" Pre-Treatment Approach to Boost Sterile Insect Technique for Mosquitoes

Chinese researchers have recently proposed a novel sex-sorting approach for the Sterile Insect Technique (SIT) in mosquitoes: adding a specific agent to the blood meal ingested by female mosquitoes, leveraging the biological difference that female mosquitoes feed on blood while males do not, to substantially reduce the number of females before release. The study was published in the June issue of the Journal of Medical Entomology. The Sterile Insect Technique is a pest population control method centered on radiation-induced sterility. Its basic process involves mass-rearing male target insects in the laboratory, sterilizing them through radiation exposure to render them reproductively incapable, and then releasing them into the field, where they mate with wild females to produce non-viable eggs, thereby suppressing target population growth. This technique has been incorporated into integrated pest management systems and is regarded as a relatively environmentally friendly pest control approach.

University of Tokyo and University of York Successfully Validate Positronium Ratio Imaging Principle for the First Time

A research team from the Graduate School of Engineering at the University of Tokyo and the University of York in the UK established a novel geometric imaging principle utilizing positron three-photon decay. Using a gamma-ray measurement system comprising scintillators and silicon photomultipliers (SiPMs), along with the existing PET radiopharmaceutical ^18F-FDG, they successfully visualized the positronium three-photon decay ratio for the first time, completing the proof-of-principle for Positronium Ratio Imaging (PRI). The findings were published in *Communications Physics*. Current clinical nuclear medicine PET examinations primarily utilize gamma rays generated from two-photon annihilation between positrons and electrons to visualize drug accumulation in the body. While this method provides quantitative information on metabolism or drug uptake, it offers limited insight into microenvironmental features such as tissue hypoxia, which are closely related to disease malignancy. In recent years, researchers have attempted to obtain additional tissue information through the average lifetime of positronium formed during positron annihilation, but this approach typically requires the introduction of special nuclides or agents, limiting its practical application.
