  • A fall mystery: why do only certain leaves turn red?

    A fall mystery: why do only certain leaves turn red?
    2026/09/28
    Leaves turn yellow in the fall because Chlorophyll breaks down, revealing the yellow pigment that was there all along. But why red? Red is a different story altogether. Leaves have to make a new pigment to turn red. Why would a dying leaf go an extra mile to do that? Scientists don’t really know. NPR science correspondent Nell Greenfieldboyce reports on the leading hypotheses out there.

    Read more of Nell's reporting on this topic.

  • 'Super' El Niño is coming. What should you expect?

    'Super' El Niño is coming. What should you expect?
    2026/09/25
    The world is bracing for the worst effects of a Super El Niño. Or a Godzilla El Niño. But what does that really even mean?

    For millennia El Niño has shaped weather across the globe, fueling flooding in parts of the U.S., droughts and wildfires in Australia and Indonesia, and disrupting fisheries across the Pacific.

    Scientists have long wondered if human activities — chiefly the burning of fossil fuels — are making El Niños stronger. Now, on the eve of the strongest El Niño on record, a team of researchers think they have an answer.

  • Vaccinated or not, we’re on the brink of a measles epidemic

    Vaccinated or not, we’re on the brink of a measles epidemic
    2026/09/23
    Measles is making a comeback. Ongoing outbreaks in Pennsylvania, South Carolina, Texas, and Utah have documented hundreds of cases, mostly among unvaccinated people. And while local and federal politicians debate the definitions and impact of those measles-associated deaths, health experts worry that we’re overlooking the real problem: the threat of a full-scale epidemic. Today, we talk to one of those experts – epidemiologist Michael Mina – to figure out who’s most at risk and whether there’s any way for us to turn this epidemic around.
