  • Never had the flu? Scientists may know why

    Never had the flu? Scientists may know why
    Apr 3 2026
    Scientists estimate somewhere between 5%-35% of people do not get sick from the flu despite being exposed to the virus that causes it. Now, researchers may have figured out why. The team looked at mouthwash samples from 19 healthcare workers who, despite frequent contact with infected patients, report never getting flu symptoms. Today on Short Wave, we talk about how what they found could help scientists develop treatments and strategies to protect people who do get the flu.

  • Why is NASA going to the moon again?

    Why is NASA going to the moon again?
    Apr 1 2026
    NASA’s Artemis II mission is set to launch this week, which could bring humanity close to the moon for the first time since 1972. It’s a mission that’s over twenty years in the making – and even though it’s not the first venture out to the moon, it still involves a lot of firsts. If all goes to plan, the mission will bring the first woman, person of color and non-American close to the moon. But why are we embarking on a sequel space mission to begin with? And while they’re up in space, what could scientists learn about the possibility of life in space for those of us still on Earth?

  • Predicting spring bloom is an art and a science

    Predicting spring bloom is an art and a science
    Mar 31 2026
    Do you ever wish you could predict the future? The National Park Service in Washington D.C. does it every year when they forecast when the Capitol’s cherry blossoms will reach peak bloom. People travel from all over the world to enjoy the annual National Cherry Blossom Festival and to glimpse these fragile flowers before they are gone. On this month’s Nature Quest, we learn the ins and outs of cherry tree blossoms, how scientists make that big prediction every year — and why all this focus on blooms can help scientists better understand climate change.

    This episode is part of Nature Quest, our monthly segment from listeners noticing a change in the world around them. To participate, send a voice memo to shortwave@npr.org with your name, location and your question about a change you're seeing in nature!

    Want to learn more about nature’s calendar? Check out our first Nature Quest episode on whether flowers are blooming early.
