The discovery of a rare species of bee by environmental regulators has blocked the plans of tech conglomerate Meta to build an artificial intelligence data center powered by nuclear energy—at least temporarily. Numerous media outlets, including Popular Science, have reported that the unnamed species of bee was detected by regulators who were surveying the land designated for the new data center—land that is located next to an unnamed nuclear power plant from which Meta had planned to obtain electricity.

The area near the Hanford Site’s former K reactors is buzzing with activity as several of the Department of Energy’s environmental cleanup projects continue near the Columbia River in Washington state.

That’s not the only thing that’s buzzing, however. While preparing some old equipment for removal earlier this spring, workers with Central Plateau Cleanup Company (CPCCo), a contractor of the DOE Office of Environmental Management Richland Operations Office, discovered a large colony of native bees.
