The world is running out of helium — again

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.  If you liked this episode, check out our episode on aluminum's strange journey from precious metal to beer can [https://lnk.to/cb36P9].

Never had the flu? Scientists may know why

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.  If you liked this episode, check out our show on an effort to map the entire immune system [https://lnk.to/lyKF9y].

Why is NASA going to the moon again?

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? Interested in more science behind current events?

Predicting spring bloom is an art and a science

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 [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 [https://lnk.to/RwKnWs].

Space news: Project Hail Mary, Artemis, data centers

Short Wavers, we hear your requests. You want MORE! SPACE! So this is the first installment of a new segment focusing only on space news. First, we talk about the new sci-fi film Project Hail Mary and the accuracy of the science in the movie. Then, we move on to data centers in orbit, if they are better for the environment and why even send them up into space. Finally, we round out the conversation with a quick update about the upcoming Artemis II launch. The space nerds assembled for this conversation are host and astrophysicist Regina G Barber [https://www.npr.org/people/1082526815/regina-g-barber], known space enthusiast and host of All Things Considered Scott Detrow [https://www.npr.org/people/444796749/scott-detrow] and NPR science correspondent Geoff Brumfiel [https://www.npr.org/people/279612138/geoff-brumfiel].  Interested in more on space?
