Three Mile Island's cooling towers have until recently served as grave markers for America's nuclear-power industry. A s we drove through southwest Memphis, KeShaun Pearson told me to keep my window down--our destination was best tasted, not viewed. Along the way, we passed an abandoned coal plant to our right, then an active power plant to our left, equipped with enormous natural-gas turbines. Pearson, who directs the nonprofit Memphis Community Against Pollution, was bringing me to his hometown's latest industrial megaproject.

This year's Bafta Games Awards nominations have been released, and the unstoppable Clair Obscur: Expedition 33 is the front-runner once again. The role-playing adventure, made by French developer Sandfall Interactive, received 12 nominations in total, including best game, best music and best narrative. Having already swept the board at several video game award ceremonies, Expedition 33 was widely expected to feature heavily in this year's Bafta list. But, in a ceremony which aims to celebrate multimillion-dollar productions and independent games made by tiny teams, there are also some surprising inclusions and omissions. Expedition 33's 12 nominations is not a record for Bafta. In 2023, God of War Ragnarok was up for 14 awards - although it lost out on best game to independent game Vampire Survivors.

Amazon's cloud'hit by two outages caused by AI tools last year' Reported issues at Amazon Web Services raise questions about firm's use of artificial intelligence as it cuts staff Amazon's huge cloud computing arm reportedly experienced at least two outages caused by its own artificial intelligence tools, raising questions about the company's embrace of AI as it lays off human employees. A 13-hour interruption to Amazon Web Services' (AWS) operations in December was caused by an AI agent autonomously choosing to "delete and then recreate" a part of its environment, the Financial Times reported. AWS, which provides vital infrastructure for much of the internet, suffered several outages last year.

After a Falcon 9 rocket stage burned up in the atmosphere, vaporised lithium and other metals drifted over Europe. A SpaceX rocket that burned up after re-entering the atmosphere unleashed a plume of vaporised metals over Europe, a type of pollution that is expected to increase as spacecraft and satellites multiply. The upper stage of a Falcon 9, which is designed to splash down in the Pacific Ocean for possible re-use, lost control due to engine failure and fell from orbit over the north Atlantic in February 2025. We're finally solving the puzzle of how clouds will affect our climate People across Europe saw fiery debris streaking through the sky, some of which crashed behind a warehouse in Poland. Seeing the news, Robin Wing at the Leibniz Institute of Atmospheric Physics in Germany and his colleagues turned on their lidar, an instrument for atmospheric sensing.

One icy morning in February, nearly 200 people gathered in a church in downtown Richmond, Va. Most had awakened before dawn and driven in from across the state. There were Republicans and Democrats from rural farms and D.C. exurbs. They shared one goal: to fight back against AI development in a region with the largest concentration of data centers in the world. "Aren't you tired of being ignored by both parties, and having your quality of life and your environment absolutely destroyed by corporate greed?" state senator Danica Roem said, to a standing ovation. The activists--wearing homemade shirts with slogans like Boondoggle: Data Center in Botetourt County--marched to the state capitol and spent the day testifying to lawmakers about their fears over data centers' impacts on electricity, water, noise pollution, and more. Some lawmakers pledged to help: "You're getting a sh-t deal," state delegate John McAuliff told activists. The phrase captured many people's feelings toward the AI industry as a whole. Not much unites Americans these days.
