Radiolab

We fall down the looking glass with Sönke Johnsen, a biologist who finds himself staring at one of the darkest things on the planet. So dark, it’s almost like he’s holding a blackhole in his hands. On his quest to understand how something could possibly be that black, we enter worlds of towering microscopic forests, where gold becomes black, the deep sea meets the moon, and places that are empty suddenly become full.  Corrections/Clarifications: In this episode, dragonfish [https://www.mbari.org/animal/dragonfish/] are described as having teeth that slide back into their skull; that is the fangtooth fish [https://ocean.si.edu/ocean-life/fish/fangtooth-fish#:~:text=This%20aptly%20named%20fish%20(Anoplogaster,when%20its%20mouth%20is%20closed.], not the dragonfish. Though both can be ultra-black. The fishes described are the darkest things on the planet, but there are some other animals that are equally as dark, including butterflies [https://www.nature.com/articles/news040126-4], wasps [https://www.nytimes.com/2024/12/17/science/ultrablack-velvet-ant-brazil.html], and birds [https://www.sciencenews.org/article/why-some-birds-paradise-have-ultrablack-feathers].

In an episode we first aired in 2018, we asked the question, do you really need a brain to sense the world around you? To remember? Or even learn? Well, it depends on who you ask. Jad and Robert, they are split on this one. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. Along with a home-inspection duo, a science writer, and some enterprising scientists at Princeton University, we dig into the work of evolutionary ecologist Monica Gagliano, who turns our brain-centered worldview on its head through a series of clever experiments that show plants doing things we never would've imagined. Can Robert get Jad to join the march? We have some exciting news! In the “Zoozve [https://radiolab.org/podcast/zoozve]” episode, Radiolab named one of Venus's quasi-moons. Then, Radiolab teamed up with The International Astronomical Union to launch a global naming contest for one of Earth’s quasi-moons, so that you, our listeners, could help us name another, and we now have a winner!! Early next week, head over to https://radiolab.org/moon [https://radiolab.org/moon], to check out the new name for the heavenly body you all helped make happen. Sign-up for our newsletter!!

In an episode first reported in 2017, we bring you what may be, maybe the greatest gift one person could give to another.  You never know what might happen when you sign up to donate bone marrow. You might save a life… or you might be magically transported across a cultural chasm and find yourself starring in a modern adaptation of the greatest story ever told. One day, without thinking much of it, Jennell Jenney swabbed her cheek and signed up to be a donor.  Across the country, Jim Munroe desperately needed a miracle, a one-in-eight-million connection that would save him. It proved to be a match made in marrow, a bit of magic in the world that hadn’t been there before.  But when Jennell and Jim had a heart-to-heart in his suburban Dallas backyard, they realized they had contradictory ideas about where that magic came from. Today, an allegory for how to walk through the world in a way that lets you be deeply different, but totally together.  This piece was reported by Latif Nasser.  It was produced by Annie McEwen, with help from Bethel Habte and Alex Overington. Special thanks to Dr. Matthew J. Matasar, Dr. John Hill, Stephen Spellman at CIBMTR, St. Cloud State University’s Cru Chapter, and Mandy Naglich.

This holiday season, we want to take you on a trip around the heavens. First, co-host Latif Nasser, with the help of Nour Raouafi, of NASA, and an edge-cutting piece of equipment, explain how we may finally be making good on Icarus’s promise. Then, co-host Lulu Miller and Ada Limón talk about how a poet laureate goes about writing an ode to one of Jupiter’s moons. And one more thing! It is almost your last chance to make your mark on the heavens. Radiolab and The International Astronomical Union’s Quasi Moon Naming Vote comes to an end on January 1st.

The early bird gets the worm. What goes around, comes around. It’s always darkest just before dawn. We carry these little nuggets of wisdom—these adages—with us, deep in our psyche. But recently we started wondering: are they true? Like, objectively, scientifically, provably true? So we picked a few and set out to fact check them. We talked to psychologists, neuroscientists, runners, a real estate agent, skateboarders, an ornithologist, a sociologist and an astrophysicist, among others, and we learned that these seemingly simple, clear-cut statements about us and our world, contain whole universes of beautiful, vexing complexity and deeper, stranger bits of wisdom than we ever imagined.
