UPDATE: This show is sold out! But you can still RSVP for the livestream at our link in bio.

NYC, we have another LIVE SHOW for ya! It’s on Thursday, Nov 5, 2026 at 7:00 p.m. and you can get tickets at the link in our bio.

More info:
For years, we have been trying to replace parts of ourselves, from our beating hearts and other organs to the skin on our bodies to the hair on our heads. Nearly every part.

In the latest Viscera, ER Doctor Avir Mitra and Senior Correspondent Molly Webster take us into the rapidly evolving world of transplants. Then we’ll kick it with New York Times bestselling science writer Mary Roach, who spent the last couple of years traveling all over, from Sichuan Province in China to Tbilisi, Georgia, to Massachusetts General Hospital, to understand just how far we’ve come, and how far we’ll go, to replace our parts. Avir talks with his dear friend, Alin Gragossian, about one of the scariest days of both of their lives. And we ask: After all our years of trying, how close are we to convincing our bodies to accept what isn’t us?

What percentage of the food you eat everyday is… grass??

A few weeks ago, biologist and writer David George Haskell taught our very own Senior Correspondent Molly Webster all sorts of things about grass. Molly found that grass — this thing that is so common, so normal in our everyday lives, it’s become sort of invisible to us — is actually quite extraordinary.

We found out that snails have this crazy habit of STABBING each other in the head with tiny arrows. The arrows are called “love darts” because they use them when... making love. So we went out to Prospect Park in Brooklyn to hunt for snails and see if we could find a love dart in the wild.

Love darts actually have a deep evolutionary purpose. They pump hormones into their partner to make it more likely for their partner to get pregnant. The snail makes them in an organ called the dart sac. The darts are a little limestone dagger, made from the same material as the snail’s shell. Scientists have observed one kind of snail that stabs its partner 3,300 times!

If YOU find a love dart — in NYC or elsewhere — PLEASE let us know. We will be so jealous but also so excited for you.

Thanks so much to Howard Goldstein from the Prospect Park Alliance for showing us around the park! @prospect_park

You can learn more about love darts in an episode we made all about them, at the link in our bio.

Guess who ELSE is joining Radiolab at Little Island this weekend? Pilobolus! We are so stoked to have them on team Grass for three days of free, live shows.

This weekend, join us for Radiolab: Grass Fed. Radiolab senior correspondent Molly Webster reexamines the thing right under our feet: grass. It turns out, the unremarkable green stuff all around us has a remarkable story to tell, one of transforming the planet and … us. From the food we eat, to the thoughts we think.

Including live music by foley artist Steven Wendt (@stevenwendt), storytelling by biologist David George Haskell (@davidgeorgehaskell), and dance theatre company Pilobolus (@pilobolus).

Oh boy are we PUTTING ON A SHOW! Six shows, actually! And you can come, FOR FREE, to The Glade at Little Island in NYC.

The first week: Three performances of a show we’re calling “Fruit Fantasia.” We have a story about the ancient history inside a banana Laffy Taffy, the science behind how we can eat fruits year-round, and some beautiful, poetic love letters to fruit. Hosted by Matt Kielty, with special guests Ben Shattuck, Mona Pirnot, Dan Pashman, Dr. Nadia Berenstein, and Kendra Vaculin. Plus, we’re so excited to have @rafiqbhatia accompany us with LIVE music.

The second week: Three performances of “Grass Fed,” hosted by Molly Webster. Journey through all five senses to re-examine the thing right under our feet. And discover how grass—yes grass—is the largest food item in the world.

We’ll have live music, fruit for you to try, and partnerships with food vendors who are cooking up something special just for us.

Totally FREE and no tickets needed. Each show is at 5:00 p.m. The first week is July 31st-August 2nd. The second week will be August 14th-16th. Put it in your calendars! <3 More info in our bio. by @mollswebs

Here’s a real life “Would You Rather” question: Autoimmune disease, or hookworms? Which one would YOU pick? by @mollswebs

Anglerfish cultivate bioluminescent bacteria to attract prey. But how do they avoid becoming prey themselves? @Radiolab Senior reporter Molly Webster weighs in on the latest episode of @terrestrialspodcast, The Wicked Smoocha: Anglerfish Break A World Record. Listen wherever you get podcasts!

Happy 3rd Birthday to “Little Black Hole” and the readers, young and less-young, who love her (and the dog)

Expand the universe - go buy someone you know a copy (or borrow from your local library). ♥️⚫️♥️⚫️ by @mollswebs

In the depths of the ocean, a tiny male anglerfish catches a scent and follows it through the darkness. Eventually he finds a glowing, toothy female with a bacterial lightbulb on her head. He kisses her… and never lets go. Their bodies permanently fuse, merging bloodstreams, flesh, and digestive tracts.
Radiolab correspondent Molly Webster brings us the wild story of this eternal kiss (also some cool specimen photos from @amnh). We dive deeper into glowing lures, bioluminescent bacteria, and the biology of two creatures becoming one.
Plus, Alan tells us about the time he broke a world record, and marine biologist Dr. Kory Evans answers our questions about some of the weirdest fish in the sea.

🎶 You can listen to our new songs, “Anglerfish” and “Esca Disco” on Spotify, Apple Music, and wherever you get your music.
