    How to build a house on the moon

    Humans have visited the moon but we’ve never lived there. Could we build a home on our lunar neighbor? Join Molly and co-host Ira as they find out why the moon can be a dangerous place, and what it would take to live there. We’ll imagine a visit to a lunar hotel, hear about all the stuff humans have left up there and even hear a song sung by the Moon herself!

    Featured Expert: Phil Plait, astronomer, journalist and author of several books, including, Under Alien Skies: A Sightseer’s Guide to the Universe, which uses science and imagination to paint a picture of what it would be like to vacation on the moon.
    Resources:Learn more about NASA’s Artemis program which aims to bring humans back to the moon.

    Let's Go Bananas

    HARVEY, our omnipresent virtual voice assistant, gets a software update that makes him go bananas for bananas. And if we talk about anything except bananas, he turns the microphones off! We talk to geneticist Dr. Janina Jeff about how much DNA we share with a banana, find out why bananas make other fruits ripen, how bananas grow, and where that slipping on a banana peel joke came from. Speaking of jokes, we'll hear a bunch of banana jokes from listeners too! Plus: The Moment of Um answers the question: "Why are peaches fuzzy?"

    You can hear more from Dr. Jeff on her podcast In Those Genes.

    Silent film expert Lea Stans has a wonderful blog post about the history of the banana peel joke that you can read right here. You can see some of those early comics that featured the joke!
