Brive in France Tests Sterile Insect Technique Using X-Ray Irradiation to Control Tiger Mosquitoes, Preliminary Results Show Nearly 60% Sterility Rate in Mosquito Eggs

The city of Brive-la-Gaillarde in the Nouvelle-Aquitaine region of France is using the Sterile Insect Technique (SIT) to control tiger mosquitoes. Since May 2025, the city has been working with the Montpellier-based company Terratis, releasing male mosquitoes that have been treated with X-ray irradiation and rendered incapable of reproduction, in order to reduce the tiger mosquito population. The core of this method is to allow sterile males to mate with wild females, causing the females to lay eggs that cannot hatch. Although it may appear that mosquitoes are still being released in active mosquito areas, the released individuals are males, which do not bite humans. As of October 31, 2025, Brive has deployed nearly 11 million sterile male mosquitoes across 58 release points covering more than 100 hectares, with a weekly release volume of approximately 400,000...

Texas A&M University Develops Rio Red Grapefruit Through Radiation Mutagenesis, Now Accounting for About 75% of Texas Production

In 1984, researchers at Texas A&M University used radiation mutagenesis to develop the Rio Red grapefruit. Forty-two years later, this variety has become the dominant cultivar in Texas's grapefruit industry, accounting for approximately 75% of the state's total grapefruit production. The Rio Red grapefruit is distinguished by its vibrant pink flesh, as well as its greater cold tolerance and higher yields compared to other grapefruit varieties. These traits have facilitated its widespread adoption across Texas growing regions, gradually establishing it as a representative grapefruit variety in the local market. Grapefruit itself was not originally a product of artificial breeding. The earliest known grapefruit seedlings appeared in Barbados in the 18th century, resulting from a cross between the Jamaican sweet...

Uzbekistan Approves Radiation Accident Emergency Procedures for Nuclear Power Plants

Uzbekistan has approved radiation accident emergency procedures for nuclear power plants, specifying the handling procedures when nuclear power plants face the threat of or actually experience radiation accidents. The document was approved by the Industrial, Radiation and Nuclear Safety Committee under the Cabinet of Ministers, registered with the Ministry of Justice, and entered into force on August 20. The procedures apply to the siting, design, construction and operation stages of nuclear power plants, covering the conditions for activating emergency states, radiation dose rate criteria, operational information reporting processes, and requirements for emergency rescue organizations. According to the procedures, the emergency states of nuclear power plants are divided into two levels: emergency preparedness and emergency condition. When the former is activated, it generally means that the safe operation limits or conditions of the nuclear power plant have been exceeded, while the ionizing radiation dose rate has reached the corresponding threshold. If external natural or man-made events such as earthquakes, explosions, fires, or floods occur at the site and affect safety-related systems or safe operating conditions, an "emergency preparedness" state may also be declared.
