Prediabetes is common in the U.S. — around 1 in 3 people have it. And many people may not know they have it. But last year, the FDA approved the first over-the-counter continuous glucose monitor. Since then, more people without diabetes have started checking their blood glucose levels. Diabetologist and University of California, San Francisco professor of medicine Dr. Sarah Kim shares the science behind blood glucose with host Emily Kwong. Check out more of NPR’s coverage about continuous glucose monitors.Interested in more science of the human body?

Folge vom 28.11.2025What’s In A Kiss? 21 Million Years Of EvolutionHow far back in evolutionary history does kissing go? Through phylogenetic analysis, an international team of scientists found that kissing was likely present in the ancestor of all apes – which lived 21 million years ago. Not only that: They were definitely kissing Neanderthals. The study was published in the journal Evolution and Human Behavior. In this news roundup, we also talk about new clues about the collision that created our moon and a moss surviving the hardships of space.Interested in stories about human evolution?

Folge vom 25.11.2025Nature Quest: The Earthquake Prediction ProblemTheir whole life, producer Hannah Chinn has known about the Big One: a massive earthquake forecasted to hit the West Coast. Scientists say it’ll destroy buildings, collapse bridges, flood coastal towns and permanently shift the landscape. But how exactly do scientists know this much about the scope of earthquakes if they can’t even predict when those earthquakes are going to happen? Together with host Emily Kwong, Hannah goes on a quest for answers. Plus, they get into what a Cascadia earthquake has in common with a Thanksgiving turkey.This story is part of Nature Quest, our monthly segment that brings you a question from a Short Waver who is noticing a change in the world around them.
