The world's nuclear plants set a record in 2024, generating more electricity than in any previous year while helping avoid 2.1 billion tonnes of carbon dioxide emissions. At the same time, the United States is moving to license new reactor designs for the first time in decades - designs that work very differently from the plants built in the 1970s. At its core, a nuclear reactor does the same...

Antibiotics have saved hundreds of millions of lives since Alexander Fleming spotted a mold killing bacteria in a Petri dish in 1928. But bacteria fight back, and right now antibiotic resistance is killing more than a million people a year, with projections putting the cumulative death toll at 39 million or more by 2050. This episode starts with the basics: how antibiotics actually work by targeti...

Most of us have heard we need eight hours of sleep, but that number only tells part of the story. What actually happens inside your body and brain during those hours turns out to be a lot more intricate than a simple timer running down.
