In this conversation. ROBERT: Special thanks to Dr. Teresa Ryan of the University of British Columbia, Faculty of Forestry, to our intern Stephanie Tam, to Roy Halling and the Bronx Botanical Garden, and to Stephenson Swanson there. Yeah. MONICA GAGLIANO: Yeah, tested it in my lab. And then all the other ones go in the same direction. ], Dylan Keefe is our Director of Sound Design. JENNIFER FRAZER: An anti-predator reaction? ROBERT: She took that notion out of the garden into her laboratory. JENNIFER FRAZER: Oh, yeah. LARRY UBELL: Yes, we are related. She says one of the weirdest parts of this though, is when sick trees give up their food, the food doesn't usually go to their kids or even to trees of the same species. Was it possible that maybe the plants correctly responded by not opening, because something really mad was happening around it and it's like, "This place is not safe.". And then someone has to count. This way there is often more questions than answers, but that's part of the fun as well. LARRY UBELL: Good. If a plant doesn't have a brain what is choosing where to go? ROBERT: Give it to the new -- well, that's what she saying. I wanted to talk to them because, as building inspectors they -- there's something they see over and over and over. Because tree roots and a lot of plant roots are not actually very good at doing what you think they're doing. Oh! ROBERT: And for the meat substitute, she gave each plant little bit of food. So you just did what Pavlov did to a plant. In the little springtail bodies there were little tubes growing inside them. I'm gonna just go there. It'd be all random. ROBERT: So they followed the sound of the barking and it leads them to an outhouse. MONICA GAGLIANO: My reaction was, "Oh ****!" ROBERT: Now that's a very, you know, animals do this experiment, but it got Monica thinking. And if you don't have one, by default you can't do much in general. And moved around, but always matched in the same way together. So the -- this branching pot thing. ROBERT: You don't know what your dog was? They still did not close when she dropped them. Couple minutes go by And all of a sudden we could hear this barking and yelping. They're all out in the forest. I'm gonna just go there. Like the bell for the dog. LARRY UBELL: No, I don't because she may come up against it, people who think that intelligence is unique to humans. So it's not that it couldn't fold up, it's just that during the dropping, it learned that it didn't need to. MONICA GAGLIANO: Light is obviously representing dinner. ROBERT: So I think what she would argue is that we kind of proved her point. Pics! It's as if the individual trees were somehow thinking ahead to the needs of the whole forest. And the tubes branch and sometimes they reconnect. They still did not close when she dropped them. Along with a home-inspection duo, a science writer, and some enterprising scientists at Princeton University, wedig into the work of evolutionaryecologist Monica Gagliano, who turns ourbrain-centered worldview on its head through a series of clever experiments that show plants doing things we never would've imagined. JENNIFER FRAZER: They had learned to associate the sound of the bell ROBERT: Which has, you know, for dogs has nothing to do with meat. ], [ROY HALLING: Dylan Keefe is our Director of Sound Design. She's working in the timber industry at the time. ROBERT: Eventually, she came back after ROBERT: And they still remembered. No, I don't because she may come up against it, people who think that intelligence is unique to humans. We've all seen houseplants do that, right? ROBERT: And she goes on to argue that had we been a little bit more steady and a little bit more consistent, the plants would have learned and would have remembered the lesson. Never mind. Then he would bring them the meat and he would ring a bell. So light is -- if you shine light on a plant you're, like, feeding it? So they didn't. So they didn't. Favorite 46 Add to Repost 7. Pulled out a is that a root of some sort? So you are related and you're both in the plumbing business? So, okay. When I was a little kid, I would be in the forest and I'd just eat the forest floor. He's not a huge fan of. [laughs]. Yeah, it might run out of fuel. You got the plant to associate the fan with food. A given episode might whirl you through science, legal history, and into the home of someone halfway across the world. ROBERT: All right, that's it, I think. I spoke to her with our producer Latif Nasser, and she told us that this -- this network has developed a kind of -- a nice, punny sort of name. So I don't have an issue with that. So what does the tree do? AATISH BHATIA: This feels one of those experiments where you just abort it on humanitarian grounds, you know? Nothing delicious at all.". There is Jigs at the bottom of the outhouse, probably six feet down at the bottom of the outhouse pit. Exactly. I mean, I think there's something to that. Like, would they figure it out faster this time? More information about Sloan at www.sloan.org]. ROBERT: But the drop was just shocking and sudden enough for the little plant to ROBERT: Then Monica hoists the plant back up again and drops it again. Pulled out a is that a root of some sort? Take it. ROBERT: Of the tree's sugar goes down to the mushroom team? And the salivation equivalent was the tilt of the plant? Robert Krulwich. It involves a completely separate organism I haven't mentioned yet. The bell, the meat and the salivation. ROBERT: And when you measure them, like one study we saw found up to seven miles of this little threading JAD: What is this thing? Would they stay in the tree, or would they go down to the roots? MONICA GAGLIANO: Light is obviously representing dinner. I mean, it's a kind of romanticism, I think. JENNIFER FRAZER: Then he would bring them the meat and he would ring a bell. ROBERT: Again, science writer Jennifer Frazer. We're carefully examining the roots of this oak tree. He's on the right track. I don't know yet. ROBERT: Huh. And the pea plants are left alone to sit in this quiet, dark room feeling the breeze. Back and forth. I'll put it down in my fungi. JENNIFER FRAZER: So Pavlov started by getting some dogs and some meat and a bell. Listen to Radiolab: Smarty Plants, an episode of Wilderness Radio, easily on Podbay - the best podcast player on the web. ROBERT: I wanted to talk to them because, as building inspectors they -- there's something they see over and over and over. It's gone. So they might remember even for a much longer time than 28 days. One tree goes "Uh-oh." Can Robert get Jad to join the march? ROBERT: And the classic case of this is if you go back a few centuries ago, someone noticed that plants have sex. Fan, light, lean. It's like, no, no, I don't do that. Pics! So its resources, its legacy will move into the mycorrhizal network into neighboring trees. As soon as we labeled them, we used the Geiger counter to -- and ran it up and down the trees, and we could tell that they were hot, they were boo boo boo boo boo, right? No, it's because it's like every time I close my eyes, you're coming at it from a different direction. I mean, what? They just don't like to hear words like "mind" or "hear" or "see" or "taste" for a plant, because it's too animal and too human. We were so inconsistent, so clumsy, that the plants were smart to keep playing it safe and closing themselves up. ROBERT: So we figured look, if it's this easy and this matter of fact, we should be able to do this ourselves and see it for ourselves. ALVIN UBELL: How much longer? The little threads just wrapping themselves around the tree roots. Yes. ANNIE: But I wonder if her using these metaphors ANNIE: is perhaps a very creative way of looking at -- looking at a plant, and therefore leads her to make -- make up these experiments that those who wouldn't think the way she would would ever make up. We are the principals of Accurate Building Inspectors of Brooklyn, New York. So they figured out who paid for the murder. Remember that the roots of these plants can either go one direction towards the sound of water in a pipe, or the other direction to the sound of silence. [laughs]. There was a healthier community when they were mixed and I wanted to figure out why. Yeah, mimosa has been one of the pet plants, I guess, for many scientists for, like, centuries. MONICA GAGLIANO: So, you know, I'm in the dark. And he starts digging with his rake at the base of this tree. It turns that carbon into sugar, which it uses to make its trunk and its branches, anything thick you see on a tree is just basically air made into stuff. We need to take a break first, but when we come back, the parade that I want you to join will come and swoop you up and carry you along in a flow of enthusiasm. MONICA GAGLIANO: I wonder if that was maybe a bit too much. And so I don't have a problem with that. And all of a sudden, one of them says, "Oh, oh, oh, oh! Ring, meat, eat. They learned something. Kind of even like, could there be a brain, or could there be ears or, you know, just sort of like going off the deep end there. JENNIFER FRAZER: And his idea was to see if he could condition these dogs to associate that food would be coming from the sound of a bell. Robert, I have -- you know what? Was it possible that maybe the plants correctly responded by not opening, because something really mad was happening around it and it's like, "This place is not safe.". But maybe it makes her sort of more open-minded than -- than someone who's just looking at a notebook. JENNIFER FRAZER: And this is what makes it even more gruesome. You have to understand that the cold water pipe causes even a small amount of water to condense on the pipe itself. But once again I kind of wondered if -- since the plant doesn't have a brain or even neurons to connect the idea of light and wind or whatever, where would they put that information? Thud. But I wonder if her using these metaphors is perhaps a very creative way of looking at -- looking at a plant, and therefore leads her to make -- make up these experiments that those who wouldn't think the way she would would ever make up. But we are in the home inspection business. But instead of dogs, she had pea plants in a dark room. SUZANNE SIMARD: Like, nitrogen and phosphorus. This is not so good" signal through the network. ROBERT: Yeah. ROBERT: I do want to go back, though, to -- for something like learning, like, I don't understand -- learning, as far as I understand it, is something that involves memory and storage. When we last left off, I'm just saying you just said intelligence. Me first. ROBERT: Okay. Sugar. Yeah. Just the sound of it? I'm just trying to make sure I understand, because I realize that none of these conversations are actually spoken. But instead of dogs, she had pea plants in a dark room. ROBERT: So we strapped in our mimosa plant. I was like, "Oh, my God! Or maybe slower? ROBERT: And the salivation equivalent was the tilt of the plant? As abundant as what was going on above ground. I don't know where you were that day. Is your dog objecting to my analysis? Ring, meat, eat. ROBERT: She says what will happen under the ground is that the fungal tubes will stretch up toward the tree roots, and then they'll tell the tree SUZANNE SIMARD: With their chemical language. So the roots can go either left or to the right. And so they have this trading system with trees. And so of course, that was only the beginning. Jad and Robert, they are split on this one. JAD: Where would the -- a little plant even store a memory? And the salivation equivalent was the tilt of the plant? No boink anymore. And might as well start the story back when she was a little girl. I mean, I -- it's a kind of Romanticism, I think. And on this particular day, she's with the whole family. I mean, this is going places. ROBERT: That is actually a clue in what turns out to be a deep, deep mystery. And her family included a dog named Jigs. This is the headphones? And the -- I'm gonna mix metaphors here, the webs it weaves. But I wonder if her using these metaphors is perhaps a very creative way of looking at -- looking at a plant, and therefore leads her to make -- make up these experiments that those who wouldn't think the way she would would ever make up. Well, it depends on who you ask. So now, they had the radioactive particles inside their trunks and their branches. And it was almost like, let's see how much I have to stretch it here before you forget. And so we're up there in this -- in this old forest with this guy. JENNFER FRAZER: Well, they do it because the tree has something the fungus needs, and the fungus has something the tree needs. Charts. It's like every time I close my eyes, you're coming at it from a different direction. Kind of even like, could there be a brain, or could there be ears or, you know, just sort of like going off the deep end there. Do you really need a brain to sense the world around you? We ask deep questions and use investigative journalism to get the answers. Why is this network even there? And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. A plant that is quite far away from the actual pipe. There's this whole other world right beneath my feet. ROBERT: And I wanted to talk to them because, as building inspectors they -- there's something they see over and over and over. ROBERT: And I met a plant biologist who's gonna lead that parade. ROBERT: And she goes into that darkened room with all the pea plants. Smarty Plants by Radiolab | Podchaser Episode from the podcast Radiolab Next Episode Smarty Plants Released Wednesday, 14th February 2018 3 people rated this episode About Insights Pro Reviews Creators 9 Lists 1 Do you really need a brain to sense the world around you? You need the nutrients that are in the soil. JAD: And to Annie McEwen and Brenna Farrow who both produced this piece. Does it threaten my sense of myself or my place as a human that a plant can do this? No, it's far more exciting than that. And so I designed this experiment to figure that out. There's not a leak in the glass. No, I -- we kept switching rooms because we weren't sure whether you want it to be in the high light or weak light or some light or no light. No. No. Yeah, it might run out of fuel. Yeah, and I have done inspections where roots were coming up through the pipe into the house. They're not experiencing extra changes, for example. ROBERT: So you can -- you can see this is like a game of telephone. JAD: So she's saying they remembered for almost a month? ], This is Jennifer Frazer, and I'm a freelance science writer and blogger of The Artful Amoeba at Scientific American. ROBERT: She took some plants, put them in a pot that restricted the roots so they could only go in one of just two directions, toward the water pipe or away from the water pipe. So they didn't. And so of course, that was only the beginning. ROBERT: Truth is, I think on this point she's got a -- she's right. In the podcast episode Smarty Plants, the hosts talk about whether or not you need a brain to sense the world around you; they shared a few different anecdotes, . Crossposted by 4 years ago. ROBERT: So if all a tree could do was split air to get carbon, you'd have a tree the size of a tulip. Gebel. This happens to a lot of people. I wonder if that was maybe a bit too much. Or even learn? ROBERT: What's its job? Is there anyone whose job it is to draw a little chalk outlines around the springtails? So Monica moves the fans to a new place one more time. My name is Monica Gagliano. Yeah, I know. ROBERT: This final thought. But maybe it makes her sort of more open-minded than -- than someone who's just looking at a notebook. ROBERT: And this? On our knees with our noses in the ground, and we can't see anything. And I remember it was Sunday, because I started screaming in my lab. So they can't move. Five, four, three, two, one, drop! So you -- if you would take away the fish, the trees would be, like, blitzed. That apparently -- jury's still out. You just used a very interesting word.
