  • Soil & Global Warming

    Soil & Global Warming 

    One of the biggest environmental worries is global warming, which is caused by greenhouse gases like carbon dioxide. In this Science Update, you'll hear how dirt might help fight it.

  • Smelling Diseases

    Smelling Diseases 

    We all use our noses to make quick judgments from time to time—whether it's checking to see if the milk's still good, or if a shirt needs to go in the wash. This Science Update discusses how doctors are developing a kind of sniff test to screen for diseases.

  • WWII Tree Disease

    WWII Tree Disease 

    In this Science Update, learn about the unintended consequences of military invasions on a region's natural environment.

  • Gold Mine Quakes

    Gold Mine Quakes 

    Studying small earthquakes earthquakes in gold mines can help scientists learn more about major earthquakes.

  • Cicada Cycles

    Cicada Cycles 

    Cicadas spend years underground and come out once in a blue moon for a frenzy of activity. But certain broods, like the one that emerged in 2004, come out like clockwork every 13 or 17 years. In this Science Update, you'll hear what's so special about these numbers.

  • Cicada Emergence

    Cicada Emergence 

    Every 13 or 17 years, some parts of the country are on cicada watch. They're waiting for billions of the thumb-sized insects to crawl out of the ground, create an incredible racket with their calls, and then die after successfully mating. One Science Update listener asked how the bugs know when to finally come out.

  • Dogs and Their Owners
