How next-generation nuclear reactors break out of the 20th-century blueprint
The popularity of commercial nuclear reactors has surged in recent years as worries about climate change and energy independence drowned out concerns about meltdowns and radioactive waste. The problem is, building nuclear power plants is expensive and slow.
A new generation of nuclear power technology could reinvent what a reactor looks like—and how it works. Advocates hope that new tech can refresh the industry and help replace fossil fuels without emitting greenhouse gases. Here’s what that might look like.

Data centers are amazing. Everyone hates them.
The hyperscale datacenter is a marvel of our age. A masterstroke of engineering across multiple disciplines. They are nothing short of a technological wonder. People hate them.
People hate them in Virginia, which leads the nation in their construction. They hate them in Nevada, where they slurp up the state’s precious water. They hate them in Michigan, and Arizona, and South Dakota. They hate them all around the world, it’s true. But they really hate them in Georgia. Read our story about why they’re provoking so much fury.

What Africa needs to do to become a major AI player
Africa is still early in the process of adopting AI technologies. But researchers say the continent is uniquely hospitable to it for several reasons, including a relatively young and increasingly well-educated population, a rapidly growing ecosystem of AI startups, and lots of potential consumers.
However, ambitious efforts to develop AI tools that answer the needs of Africans face numerous hurdles. Taken together, researchers worry, they could hold Africa’s AI sector back and hamper its efforts to pave its own pathway in the global AI race. Read the full story.
