The cyber weapon that might have prevented nuclear war.The U.S. and Israel have long been in conflict with Iran over their nuclear development program. Some of that conflict has been out in the open, with bombs and blockades, but some of it has been invisible. Recently some security researchers discovered a cyberweapon likely tied to that invisible conflict. It looks like it was designed to hide on nuclear scientists computers, then throw off their calculations--just as they got close to achieving their goals.Sounds like something out of science fiction. But it was created 20 years ago. On today’s show: a whodunit about hackers, ‘Cyber Paleontologists’, spy-vs-spy protocols, cryptic intelligence leaks, nuclear physics, high-precision math, and epistemological warfare.Pictured: Juan Andres Guerrero Saade (JAGS) and his ‘Fast16 - NOTHING TO SEE HERE, CARRY ON’ tattoo. Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebookThis episode was hosted by Nick Fountain and Erika Beras.

Can the government stop you from cutting down your own tree? In many towns and cities these days, removing a tree now requires a permit. You might have to pay a fee, or promise to plant replacement trees. But sometimes, the city won't let you cut down the tree at all, even a tree in your own backyard.That's because trees are important for air quality, for flood control, and for public health. They help keep neighborhoods cool on hot days. But some think that tree protection laws have gone too far — that they might even be unconstitutional.On today's episode, it's the latest showdown between property rights and local zoning laws. Typically, towns and cities enjoy a lot of power when it comes to zoning and permits. They can ban certain types of buildings. They can make you paint your house a certain color. But can they make it illegal to cut down a tree? And what does it mean to "own" a piece of property anyway?Support:Planet Money+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebookThis episode of Planet Money was hosted by Jeff Guo and Amanda Aronczyk.

One specific type of affordable housing used to be popular in American cities, kept rents low, then nearly vanished. Is it time to reconsider boarding houses and single room occupancy units? If they lowered rents in cities, why did they go away? We have the history.Then, let’s talk about corporate landlords. They’re blamed for driving up rents. Studies show they do the opposite. When corporate landlords come to town, they do buy up homes, which can raise the price to buy, but at the same time lower rents. We’ll parse the impact as we consider a Trump administration plan to restrict corporate home ownership.Related episodes:Is the YIMBY movement doomed? How to fix a housing shortage How to build abundantlyCan Trump make buying a home more affordable?Support:NPR+Read: Our book: Planet Money: A Guide to the Economic Forces That Shape Your Life Our weekly longform Planet Money newsletterOur weekly Indicator round-up newsletterFollow: InstagramTikTokYouTubeFacebookThe original episodes of the Indicator were hosted by Darian Woods and Wailin Wong.
