The U.S. tested nuclear weapons until the early 1990s. Since then, scientists have been using supercomputers and experiments to simulate nuclear test detonations, without detonating any nukes. But there are signs the world's nuclear powers may be readying to test again: Russia, China and the U.S. are all upgrading their nuclear test sites.NPR science correspondent Geoff Brumfiel was among a small group of journalists allowed to tour an underground laboratory where this research happens.

A lot of short daily news podcasts focus on just one story, but right now you probably need more. On Up First from NPR, we bring you three of the world's top headlines every day in under 15 minutes. Because no one story can capture all that's happening in this big, crazy world of ours on any given morning. Listen now to the Up First podcast from NPR.
Hey, short wavers, before we get started, quick little favor to ask. Can you help us shape the future of shortwave by completing a short anonymous survey? It's a chance for you to tell us about what you like and don't and how we can serve you better. It's an awesome responsibility, but I trust you. And we want to hear from everyone, whether you're a day one or brand new listener.
Just go to npr.org slash shortwave survey. We'll also put a link in our show notes. Thank you. Okay, on to our show. You're listening to Shortwave from NPR. Hey, Gina. Hey, NPR science correspondent Jeff Brumfield. Why are you darkening my doorstep?
To talk about one of my all-time favorite topics, nuclear weapons testing. And I got a question for you. Okay. When do you think is the last time the U.S. tested a nuclear weapon?
I'm going to say possibly in the late 70s.
They actually stopped a lot later than that. They stopped in 1992. Wow. Yeah. And they've been pursuing a very different program based on science. And recently, I got a very, very unusual look at that program and all its facets and sort of how the U.S. continues to verify its nuclear weapons work without having to set any of them off.
Are they thinking about testing again?
I would say the official answer is no, but. There is more concern that the U.S. or another country might soon test another nuclear weapon.
So today on the show, Jeff takes us on a rare trip to tunnels deep under the Nevada desert, where America does science instead of nuclear testing. I'm Regina Barber, and you're listening to Shortwave, the science podcast from NPR.
