  • Why are bees special? We get inside a hive to find out

    Why are bees special? We get inside a hive to find out
    Apr 7 2026
    In a new National Geographic docuseries, viewers get a look inside a bee hive. The series is called Secrets of the Bees — and since there’s nobody we know who loves bees more than entomologist Sammy Ramsey, we brought him on the show to share some of these secrets. We cover how bees play together (yes, play!), their ability to fend off predators four-times their size and a mite wreaking havoc on honeybees everywhere.

  • The world is running out of helium — again

    The world is running out of helium — again
    Apr 6 2026
    Lots of people count on helium. From MRI machines and semiconductor manufacturing to pressurizing rockets and detecting leaks, helium is used globally for much more than party balloons. So when there’s a shortage, like right now, the effect is far-reaching. But before the current shortage started, there was already a finite supply on Earth. So, today on Short Wave, we revisit our episode on the history of helium and how the world uses it today.

  • 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.
