Mexican authorities announced last week that the Mediterranean fruit fly, more commonly known as the medfly, had been successfully eradicated in the state of Colima using a nuclear technique described by the International Atomic Energy Agency (IAEA) as “birth control for pests.” Mexico used the sterile insect technique (SIT) in cooperation with the IAEA and the Food and Agricultural Organization of the United Nations (FAO) to protect fruit and vegetable crops, farmers’ livelihoods, and the country’s economy.
All 92 U.S. power reactors operating today need water—in the right place and at the right time. But extreme weather events, including floods, droughts, hurricanes, and heat waves, upend expectations and demand resilience: the ability to anticipate, accommodate, and recover from adverse impacts.
Resilience was built into today’s nuclear power plants decades ago. Weather data and climate forecasts not available then can be factored into risk analysis now to ensure the plants remain resilient in a changing climate.

California-based TAE Technologies has announced that its accomplishments with its fifth-generation fusion research reactor, Norman, have allowed it to secure sufficient strategic and institutional investments to fund the construction of its sixth-generation research reactor, Copernicus.
Researchers at Idaho National Laboratory (INL) recently performed their first digital twin test of the Microreactor Agile Non-nuclear Experimental Testbed (MAGNET) and captured the demonstration in a video posted July 14. The digital twin—a virtual representation of a microreactor—was built using advancements in remote monitoring, autonomous control, and predictive capabilities that could help lower operating costs of microreactor technologies and enhance their safety.
A wager struck by two plasma physicists 34 years ago was finally fulfilled in June during the opening day of the 48th European Physical Society Division of Plasma Physics, when Robert Goldston, former director of the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), virtually presented a plaque to his friend and colleague Jean Jacquinot, former director of the Joint European Torus (JET), EUROfusion's flagship fusion experiment based at the Culham Centre for Fusion Energy in the United Kingdom. Their bet, and JET’s record-breaking achievements in 2021, were celebrated in an article published by PPPL on July 8.
Researchers at General Atomics (GA) are proposing a breeding blanket made of modular silicon carbide–based components to withstand the intense conditions in a high-power fusion power plant.
