By Thomas Macaulayarchive pageMarch 18, 2026 This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. The Pentagon is planning for AI companies to train on classified data, defense official says The Pentagon plans to set up secure environments for generative AI companies to train military-specific versions of their models on classified data, MIT Technology Review has learned. AI models like Anthropic's Claude are already used to answer questions in classified settings, including for analyzing targets in Iran. But allowing them to train on and learn from classified data is a major new development that presents unique security risks. It would embed sensitive intelligence—like surveillance reports or battlefield assessments—into the models themselves. It would also bring AI firms closer to classified data than ever before.

—James O'Donnell What do new nuclear reactors mean for waste? The way the world currently deals with nuclear waste is as creative as it is varied: drown it in water pools, encase it in steel, bury it hundreds of meters underground. But an approaching wave of new reactors could introduce fresh challenges to nuclear waste management. The new designs and materials could require some engineering solutions. And there’s a huge range of them coming, meaning there’s an equally wide range of potential waste types to handle. Read the full story.

MIT Technology Review Narrated: how uncrewed narco subs could transform the Colombian drug trade For decades, handmade narco subs have been among the cocaine trade’s most elusive and productive workhorses, ferrying tons of drugs from Colombia to the rest of the world. Now off-the-shelf technology—Starlink terminals, plug-and-play nautical autopilots, high-resolution video cameras—may be advancing that cat-and-mouse game into a new phase. Uncrewed subs could move more cocaine over longer distances, and they wouldn’t put human smugglers at risk of capture. Law enforcement agencies are only just beginning to grapple with the consequences. —Eduardo Echeverri López This is our latest story to be turned into an MIT Technology Review Narrated podcast, which we’re publishing each week on Spotify and Apple Podcasts.

One More Thing AP Photo/Alex Brandon How the Pentagon is adapting to China’s technological rise It’s been just over a year since Kathleen Hicks stepped down as US deputy secretary of defense. As the highest-ranking woman in Pentagon history, Hicks shaped US military posture through an era defined by renewed competition between powerful countries and a scramble to modernize defense technology.
In this conversation with MIT Technology Review, Hicks reflects on how the Pentagon is adapting—or failing to adapt—to a new era of geopolitical competition. She discusses China’s technological rise, the future of AI in warfare, and her signature initiative: Replicator.
