Animal, heal thyself
Many Minds
What happens to animals when they get sick? If they’re pets or livestock, we probably call the vet. And the vet may give them drugs or perform a procedure. But what about wild animals? Do they just languish in misery? Well, not so much. It turns out that animals—from bees to butterflies, porcupines to primates—medicate themselves. They seek out bitter plants, they treat wounds, they amputate limbs, they eat clay—the list goes on. This all raises an obvious question: How do they know to do this? How do they know what they know about healing and medicine? It also invites a related...

The rise of machine culture
Many Minds
The machines are coming. Scratch that—they're already here: AIs that propose new combinations of ideas; chatbots that help us summarize texts or write code; algorithms that tell us who to friend or follow, what to watch or read. For a while the reach of intelligent machines may have seemed somewhat limited. But not anymore—or, at least, not for much longer. The presence of AI is growing, accelerating, and, for better or worse, human culture may never be the same. My guest today is . Iyad directs the at the Max Planck Institute for Human Development in Berlin. Iyad is a...

How should we think about IQ?
Many Minds
IQ is, to say the least, a fraught concept. Psychologists have studied IQ—or g for “general cognitive ability”—maybe more than any other psychological construct. And they’ve learned some interesting things about it. That it's remarkably stable over the lifespan. That it really is general: people who ace one test of intellectual ability tend to ace others. And that IQs have risen markedly over the last century. At the same time, IQ seems to be met with increasing squeamishness, if not outright disdain, in many circles. It's often seen as crude, misguided, reductive—maybe a whole lot...

Rethinking the "wood wide web"
Many Minds
Forests have always been magical places. But in the last couple decades, they seem to have gotten a little more magical. We've learned that trees are connected to each other through a vast underground network—an internet of roots and fungi often called the "wood wide web". We've learned that, through this network, trees share resources with each other. And we've learned that so-called mother trees look out for their own offspring, preferentially sharing resources with them. There's no question that this is all utterly fascinating. But what if it's also partly a fantasy? My guest today is ....

Electric ecology
Many Minds
There's a bit of a buzz out there, right now, but maybe you haven’t noticed. It's in the water, it's in the air. It's electricity—and it's all around us, all the time, including in some places you might not have expected to find it. We humans, after all, are not super tuned in to this layer of reality. But many other creatures are—and scientists are starting to take note. My guest today is . Sam is a sensory ecologist at the Natural History Museum in Berlin, and one of a handful of scientists uncovering some shocking things about the role of electricity in the natural world. Here, Sam...

The nature of nurture
Many Minds
The idea of a "maternal instinct"—the notion that mothers are wired for nurturing and care—is a familiar one in our culture. And it has a flipside, a corollary—what you might call “paternal aloofness.” It's the idea that men just aren't meant to care for babies, that we have more, you know, manly things to do. But when you actually look at the biology of caretaking, the truth is more complicated and much more interesting. My guest today is . She is Professor Emerita of Anthropology at the University of California, Davis and the author of the new book, . In it, she examines...

The space of (possibly) sentient beings
Many Minds
We may not know what it's like to be a bat, but we're pretty confident that it's like something—that bats (and other mammals) are sentient creatures. They feel pleasure and pain, cold and warmth, agitation and comfort. But when it comes to other creatures, the case is less clear. Is a crab sentient? What about a termite, or a tree? The honest answer is we just don't know—and yet, despite that uncertainty, practical questions arise. How should we treat these beings? What do we owe them? My guest today is . Jonathan is a Professor of Philosophy at the London School of Economics and the...

From the archive: Cities, cells, and the neuroscience of navigation
Many Minds
Hi friends, we're still on a brief summer break. We'll have a new episode for you later in August. In the meanwhile, enjoy this pick from our archives! ---- [originally aired September 21, 2022] If your podcast listening habits are anything like mine, you might be out for a walk right now. Maybe you’re wandering the neighborhood, just blocks from home, or maybe you’re further afield. In either case, I’m guessing you’re finding your way without too much trouble—you’re letting some intuitive sense steer you, track how far you’ve gone, tell you where to go next. This inner navigator...

From the archive: What does ChatGPT really know?
Many Minds
Hi friends, we're on a brief summer break at the moment. We'll have a new episode for you in August. In the meanwhile, enjoy this pick from our archives! ---- [originally aired January 25, 2023] By now you’ve probably heard about the new chatbot called . There’s no question it’s something of a marvel. It distills complex information into clear prose; it offers instructions and suggestions; it reasons its way through problems. With the right prompting, it can even mimic famous writers. And it does all this with an air of cool competence, of intelligence. But, if you're like me,...

Many Minds
Hi friends, we're on a brief summer break at the moment. We'll have a new episode for you in August. In the meanwhile, enjoy this pick from our archives! _____ [originally aired May 17, 2023] You know the feeling. You're trying to read or write or think through a project, maybe even just respond to an email, when your attention starts to drift. You may not even notice it until you've already picked up your phone or jumped tabs, until your mind has already wandered way off-piste. This problem of distraction has become a bit of a modern-day obsession. We now fret about how to stay focused, how...

[originally aired July 20, 2022]
The world is bigger than you think. I don’t mean geographically, though maybe that too. I mean in terms of its textures and sounds and smells; I mean in terms of its hues and vibrations. There are depths and layers to the world that we don’t usually experience, that we might actually never be able to experience. Our senses just aren’t wired to take it all in. We’re simply not tuned to all the dimensions of reality’s rich splendor. But there is a way we can appreciate these hidden dimensions: with a flex of the imagination, we can step into the worlds of other creatures; we can try out different eyes and noses; we can voyage into different perceptual universes. Or at least we can try.
My guest today is Ed Yong, author of the new book An Immense World: How Animal Senses Reveal the Hidden Realms Arounds Us. Ed is a science writer for The Atlantic and the author of an exceptional earlier book on the microbiome called I Contain Multitudes. This new book tours the wide diversity of animal senses. It asks what it’s like to be a bat, sure, but also what it’s like to be a star-nosed mole, a manatee, or a mantis shrimp. Informed by some truly extraordinary science, the book considers how it might feel to electrolocate around the ocean, to hear through the threads of a web, or to be tugged by the earth's magnetic field.
There’s a lot of praise I could lavish on this book, but I’ll just say this: it really makes you feel more alive. Reading it makes everything, in fact, seem more alive. It makes the world seem richer, more vivid, somehow more technicolor and finely textured. It makes you realize that every organism, all the creatures we share this planet with, possesses a kind of vibrant genius all their own.
After this episode we will be on a short holiday, and then we’ll be gearing up for Season 4. If you have guests or topics you want us to cover, please send us a note. And, of course: if you’ve enjoyed the show so far, we would be most grateful if you would leave us a rating or a review. I know I say this all the time, and it’s probably a bit annoying: but it really, truly helps, and I would personally, very much appreciate it!
Alright friends, now to my conversation with Ed Yong. Enjoy!
