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.

Texas to Accelerate Opening of Sterile Fly Facility to Combat New World Screwworm Outbreak

The U.S. Department of Agriculture announced that, in response to the New World screwworm (NWS) outbreak already detected in Texas and New Mexico, the sterile fly facility at Moore Air Base in Edinburg, Texas, will open early next spring, approximately seven months ahead of the original schedule. Construction on the facility began in April of this year, and once completed, it will produce sterile flies to support outbreak control efforts using the Sterile Insect Technique (SIT). Under the plan, the facility will reach full operational capacity by the end of 2028, producing approximately 300 million sterile flies per week. The Sterile Insect Technique works by releasing sterilized flies into the environment to mate with wild screwworms, thereby interrupting the reproductive cycle and reducing the risk of continued parasite spread...

French city of Illkirch plans to test sterile insect technique to combat tiger mosquitoes

Thibaud Philipps, Mayor of Illkirch-Graffenstaden in France's Bas-Rhin department, hopes to pilot the Sterile Insect Technique (SIT/TIS) locally, sterilizing male tiger mosquitoes through radiation and releasing them regularly to curb population growth. According to local authorities, tiger mosquitoes have been officially established in Illkirch-Graffenstaden since 2019. In recent years, the local tiger mosquito population has continued to increase, significantly impacting residents' daily lives. The municipal government has previously implemented multiple control measures, including launching the "Tiger Team" project in 2024 to educate the public on mosquito prevention and control methods, as well as providing subsidies of up to 50 euros per household for purchasing mosquito traps.

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.

University of Missouri Receives $1 Million Grant to Research New FLASH Radiotherapy System

On August 11, researchers at the University of Missouri School of Medicine received a $1 million grant from the National Institutes of Health to study a new technology in cancer radiotherapy—the TheryQ FLASHKNiFE system. The project is funded through June 2027. A long-standing challenge in cancer treatment is how to kill tumor cells while protecting surrounding healthy tissue as much as possible. Existing radiotherapy can already achieve millimeter-level precision, but radiation damage and related side effects still limit the dose patients can safely receive. Unlike conventional approaches, FLASH radiotherapy does not primarily alter the direction of radiation beams, but instead delivers irradiation in an extremely short time at an ultra-high dose rate...

Brazil's uranium imports from Russia hit highest since 1997 in July, reaching $84.5 million in a single month, a 168-fold surge month-on-month

Brazil's uranium imports from Russia in July this year reached $84.5 million, equivalent to approximately 430 million reais, the highest level since 1997. Compared with the import value of only $504,000 in June, the single-month increase was as high as 168-fold, indicating that this transaction was not a general monthly fluctuation but a concentrated procurement of exceptionally large scale. Looking at historical data, Brazil's uranium imports have typically remained at the level of hundreds of thousands of dollars per month, and even previous periodic peaks were far below the scale seen in July. Materials show that there was an import peak exceeding $1 million in August 2025, but it still pales in comparison with this $84.5 million figure. This means that the July data not only changes...
