So for three days, three times a day, she would shine these little blue lights on the plants. Well, when I was a kid, my family spent every summer in the forest. I mean, I see the dirt. They run out of energy. ROBERT: I'm not gonna tell you. Fan first, light after. ROBERT: Salmon consumption. ROBERT: Then she placed the fan right next to the light so that MONICA GAGLIANO: The light and the fan were always coming from the same direction. So it's predicting something to arrive. We showed one of these plants to him and to a couple of his colleagues, Sharon De La Cruz ROBERT: Because we wanted them to help us recreate Monica's next experiment. Little fan goes on, the light goes on. ROBERT: So the beetles don't want to eat them. I'm 84. It's like, no, no, I don't do that. So they just went right for the MP3 fake water, not even the actual water? Okay? JENNIFER FRAZER: So what do we have in our ears that we use to hear sound? Then we actually had to run four months of trials to make sure that, you know, that what we were seeing was not one pea doing it or two peas, but it was actually a majority. JENNIFER FRAZER: Right? But over the next two decades, we did experiment after experiment after experiment that verified that story. I'm a professor emeritus of plant biology at UC Santa Cruz. LINCOLN TAIZ: It's a very interesting experiment, and I really want to see whether it's correct or not. ALVIN UBELL: Testing one, two. I'll put it down in my fungi. ALVIN UBELL: How much longer? Princeton University News Transformations: Students find creativity at intersection of art and engineering. ROBERT: So for three days, three times a day, she would shine these little blue lights on the plants. All right, that's it, I think. No, it's far more exciting than that. ROBERT: So there is some water outside of the pipe. If you look at a root under a microscope, what you see is all these thousands of feelers like hairs on your head looking for water. The fungus were literally sucking the nitrogen out of the springtails, and it was too late to get away. ROBERT: Oh, so this is, like, crucial. ROBERT: 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. Is your dog objecting to my analysis? He was a -- what was he? This is the plant and pipe mystery. So you just did what Pavlov did to a plant. And it was almost like, let's see how much I have to stretch it here before you forget. ROBERT: These sensitive hairs he argues, would probably be able to feel that tiny difference. The problem is is with plants. If you have this kind of license, then you are only allowed to grow up to that certain height; if . Nothing happened at all. MONICA GAGLIANO: Or would just be going random? ROBERT: And then she waited a few more days and came back. JENNIFER FRAZER: And he would repeat this. Because after dropping them 60 times, she then shook them left to right and they instantly folded up again. MONICA GAGLIANO: Yeah. I mean, I -- it's a kind of Romanticism, I think. SUZANNE SIMARD: There's an enemy in the midst. Well, I have one thing just out of curiosity ROBERT: As we were winding up with our home inspectors, Alvin and Larry Ubell, we thought maybe we should run this metaphor idea by them. Me first. Little white threads attached to the roots. She's a forestry professor at the University of British Columbia. So they didn't. So the fungus is giving the tree the minerals. ROBERT: Is your dog objecting to my analysis? And what we found was that the trees that were the biggest and the oldest were the most highly connected. Same as the Pavlov. And then someone has to count. They don't do well in warm temperatures and their needles turn all sickly yellow. They somehow have a dye, and don't ask me how they know this or how they figured it out, but they have a little stain that they can put on the springtails to tell if they're alive or dead. I thought okay, so this is just stupid. Okay? And therefore she might, in the end, see something that no one else would see. But what I do know is that the fact that the plant doesn't have a brain doesn't -- doesn't a priori say that the plants can't do something. Wait a second. Like a human would. I'm gonna just go there. Like, they don't have ears or a brain or anything like, they couldn't hear like we hear. So no plants were actually hurt in this experiment. One time, the plant literally flew out of the pot and upended with roots exposed. And of course we had to get Jigs out. And when they go in SUZANNE SIMARD: There is Jigs at the bottom of the outhouse, probably six feet down at the bottom of the outhouse pit. And again. Just a boring set of twigs. April 8, 2018 By thelandconnection. say they're very curious, but want to see these experiments repeated. So we're really -- like this is -- we're really at the very beginning of this. ROBERT: And I met a plant biologist who's gonna lead that parade. They have to -- have to edit in this together. They need light to grow. And it was almost like, let's see how much I have to stretch it here before you forget. And after not a whole lot of drops, the plant, she noticed, stopped closing its leaves. So -- so carbon will move from that dying tree. What was your reaction when you saw this happen? She's working in the timber industry at the time. SUZANNE SIMARD: We had to dig from the sides. Well, 25 percent of it ended up in the tree. They shade each other out. We waiting for the leaves to, you know, stop folding. LINCOLN TAIZ: Yes. They run out of energy. The light and the fan were always coming from the same direction. And again. No, I guess that I feel kind of good to say this. ROBERT: Peering down at the plants under the red glow of her headlamp. And every day that goes by, I have less of an issue from the day before. One time, the plant literally flew out of the pot and upended with roots exposed. Or maybe slower? LARRY UBELL: No, I don't because she may come up against it, people who think that intelligence is unique to humans. So she decided to conduct her experiment. She went into the forest, got some trees. They can also send warning signals through the fungus. We went and looked for ourselves. Add to My Podcasts. ROBERT: Had indeed turned and moved toward the fan, stretching up their little leaves as if they were sure that at any moment now light would arrive. Eventually over a period of time, it'll crack the pipe like a nutcracker. And I do that in my brain. Hobbled, really. SUZANNE SIMARD: Yes, we don't normally ascribe intelligence to plants, and plants are not thought to have brains. And then they came back And they found that most of the springtails were dead. However, if that's all they had was carbon That's Roy again. ROBERT: But what -- how would a plant hear something? ROBERT: So you are related and you're both in the plumbing business? And then Monica would ROBERT: Just about, you know, seven or eight inches. Plants are amazing, and this world is amazing and that living creatures have this ability for reasons we don't understand, can't comprehend yet." And not too far away from this tree, underground, there is a water pipe. Her use of metaphor. And when I came on the scene in 19 -- the 1980s as a forester, we were into industrial, large-scale clear-cutting in western Canada. ], [ALVIN UBELL: Maria Mata -- Maria Matasar ], [LARRY UBELL: Maria Matasar-Padilla is our Managing Director. They learned something. Pulled out a is that a root of some sort? MONICA GAGLIANO: Yeah, I know. And so we're up there in this -- in this old forest with this guy. She's working in the timber industry at the time. MONICA GAGLIANO: Picasso, enough of that now. In this conversation. So its resources, its legacy will move into the mycorrhizal network into neighboring trees. Just the sound of it? Little fan goes on, little light goes on, both aiming at the pea plant from the same direction. Yeah, and I have done inspections where roots were coming up through the pipe into the house. JENNIFER FRAZER: Right? We dropped. The next one goes, "Uh-oh." I wonder if that was maybe a bit too much. Or it's just the vibration of the pipe that's making it go toward it. ROBERT: She took that notion out of the garden into her laboratory. If a plant doesn't have a brain what is choosing where to go? Turns the fan on, turns the light on, and the plant turns and leans that way. Promote. He's looking up at us quite scared and very unhappy that he was covered in And toilet paper. LARRY UBELL: We are the principals of Accurate Building Inspectors of Brooklyn, New York. So maybe the root hairs, which are always found right at the growing tips of plant roots, maybe plant roots are like little ears. Me first. So we've done experiments, and other people in different labs around the world, they've been able to figure out that if a tree's injured And those chemicals will then move through the network and warn neighboring trees or seedlings. ROBERT: say they're very curious, but want to see these experiments repeated. ROBERT: Monica's work has actually gotten quite a bit of attention from other plant biologists. Again. So light is -- if you shine light on a plant you're, like, feeding it? It's condensation. It's now the Wood Wide Web? You know, one of those little jeweler's glasses? It's almost as if the forest is acting as an organism itself. I think if I move on to the next experiment from Monica, you're going to find it a little bit harder to object to it. 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. ROBERT: And this? JAD: But still. LARRY UBELL: No, I don't because she may come up against it, people who think that intelligence is unique to humans. ROBERT: And her family included a dog named Jigs. There's -- they have found salmon in tree rings. ROBERT: They shade each other. How do you mean? I don't know. Except in this case instead of a chair, they've got a little plant-sized box. And so I was really excited. ROBERT: All right, that's it, I think. Smarty Plants. It didn't seem to be learning anything. ROBERT: But instead of dogs, she had pea plants in a dark room. ALVIN UBELL: And I've been in the construction industry ever since I'm about 16 years old. JENNIFER FRAZER: With when they actually saw and smelled and ate meat. Isn't that what you do? In 1997, a couple of scientists wrote a paper which describes how fungi JENNIFER FRAZER: Have developed a system for mining. And if you just touch it ROBERT: You can actually watch this cascade ROBERT: Where all the leaves close in, like do do do do do do. 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. Now, can you -- can you imagine what we did wrong? ROBERT: Absolutely not. I found a little water! ROBERT: He gives us a magnifying glass. It's a -- it's a three-pronged answer. ], Dylan Keefe is our Director of Sound Design. And it was almost like, let's see how much I have to stretch it here before you forget. And then all the other ones go in the same direction. 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. ROBERT: So she takes the plants, she puts them into the parachute drop, she drops them. When you go into a forest, you see a tree, a tall tree. ROY HALLING: Well, you can see the white stuff is the fungus. ROBERT: Science writer Jen Frazer gave us the kind of the standard story. Yeah. The fungi needs sugar to build their bodies, the same way that we use our food to build our bodies. These guys are actually doing it." Into which she put these sensitive plants. My reaction was like, "Oh ****!" It just kept curling and curling. JAD: So they just went right for the MP3 fake water, not even the actual water? ROBERT: So they followed the sound of the barking and it leads them to an outhouse. And again. Different kind of signal traveling through the soil? This happens to a lot of people. LARRY UBELL: Yeah, and I have done inspections where roots were coming up through the pipe into the house. Monica's work has actually gotten quite a bit of attention from other plant biologists. To play the message, press two. Imagine towering trees to your left and to your right. And then they came back JENNIFER FRAZER: And they found that most of the springtails were dead. ROBERT: So light is -- if you shine light on a plant you're, like, feeding it? Can Robert get Jad to join the march? And she was willing to entertain the possibility that plants can do something like hear. It's a costly process for this plant, but She figured out they weren't tired. Because if I let you go it's gonna be another 20 minutes until I get to talk. And if you don't have one, by default you can't do much in general. The light and the fan were always coming from the same direction. ROBERT: And then those little tubes will wrap themselves into place. Robert Krulwich. And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. Episodes. JAD: We've all seen houseplants do that, right? It's a costly process for this plant, but ROBERT: She figured out they weren't tired. Yes. And it's more expensive. ROBERT: Fan, light, lean. MONICA GAGLIANO: Again, if you imagine that the pot, my experimental pot. Could a plant learn to associate something totally random like a bell with something it wanted, like food? It's now the Wood Wide Web? In my brain. There was a healthier community when they were mixed and I wanted to figure out why. ALVIN UBELL: And I've been in the construction industry ever since I'm about 16 years old. ROBERT: 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. ROBERT: So for three days, three times a day, she would shine these little blue lights on the plants. And the plant still went to the place where the pipe was not even in the dirt? Picture one of those parachute drops that they have at the -- at state fairs or amusement parks where you're hoisted up to the top. Like, I say, it's early in the season. On one side, instead of the pipe with water, she attaches an MP3 player with a little speaker playing a recording of ROBERT: And then on the other side, Monica has another MP3 player with a speaker. Yeah, I know. ROBERT: 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? Because the only reason why the experiment turned out to be 28 days is because I ran out of time. Just a boring set of twigs. And so I don't have a problem with that. Does it threaten your sense of humanity that you depend for pretty much every single calorie you eat on a plant? 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. Like trees of different species are supposed to fight each other for sunshine, right? These guys are actually doing it." He's the only springtail with a trench coat and a fedora. MONICA GAGLIANO: Exactly, which is pretty amazing. She's not gonna use hot water because you don't want to cook your plants, you know? Plants are complex and ancient organisms. And she wondered whether that was true. That's okay. Pics! ROBERT: But what -- how would a plant hear something? ROBERT: So if a beetle were to invade the forest, the trees tell the next tree over, "Here come the --" like Paul Revere, sort of? No question there. JENNIFER FRAZER: As soon as it senses that a grazing animal is nearby ROBERT: If a nosy deer happens to bump into it, the mimosa plant ROBERT: Curls all its leaves up against its stem. ROBERT: We, as you know, built your elevator. ROBERT: Okay. Plants are amazing, and this world is amazing and that living creatures have this ability for reasons we don't understand, can't comprehend yet." Let us say you have a yard in front of your house. ], [JENNIFER FRAZER: Dylan Keefe is our Director of Sound Design. ROBERT: And you can actually see this happen. LARRY UBELL: It's not leaking. And we were able to map the network. Not really. LARRY UBELL: Good. You got the plant to associate the fan with food. Maybe not with the helmet, but yeah. I mean, to say that a plant is choosing a direction, I don't know. Fan first, light after. [laughs]. In a tangling of spaghetti-like, almost a -- and each one of those lines of spaghetti is squeezing a little bit. ROBERT: I have even -- I can go better than even that. Connecting your house to the main city water line that's in the middle of the street. JENNIFER FRAZER: Plants are really underrated. They run out of energy. This is very like if you had a little helmet with a light on it. Like for example, my plants were all in environment-controlled rooms, which is not a minor detail. PETER LANDGREN: Look at that. Ring, meat, eat. I mean, can you remember what you were doing a month ago? No. ROBERT: So here's what she did. ANNIE MCEWEN: What was your reaction when you saw this happen? 36:59. Are going to make me rethink my stance on plants. This is the fungus. Or at the time actually, she was a very little girl who loved the outdoors. Or even learn? It's like Snow White and The Seven Tubes or something. And the salivation equivalent was the tilt of the plant? MONICA GAGLIANO: Exactly. Then she takes the little light and the little fan and moves them to the other side of the plant. 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. I can scream my head off if I want to. Or it's just the vibration of the pipe that's making it go toward it. 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. But it didn't happen. That's the place where I can remember things. JAD: That is cool. ROY HALLING: The last kind of part of the root gets tangled just around the edge. What do you mean? We've all seen houseplants do that, right? 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. The fact that humans do it in a particular way, it doesn't mean that everyone needs to do it in that way to be able to do it in the first place. Into which she put these sensitive plants. So you're like a metaphor cop with a melty heart. So I think what she would argue is that we kind of proved her point. And it's more expensive. And remember, if you're a springtail, don't talk to strange mushrooms. 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. Oh, so this is, like, crucial. And so on. And so I was really excited. They will send out a "Oh, no! ], Test the outer edges of what you think you know. She says a timber company would move in and clear cut an entire patch of forest, and then plant some new trees. Fan, light, lean. They can go north, south, east, west, whatever. Her use of metaphor. So if a beetle were to invade the forest, the trees tell the next tree over, "Here come the --" like Paul Revere, sort of? Me first. Image credits: Photo Credit: Flickred! In this story, a dog introduces us to a strange creature that burrows . The plants have to keep pulling their leaves up and they just get tired. AATISH BHATIA: So this is our plant dropper. ROBERT: And then later, scientists finally looked at these things under much more powerful microscopes, and realized the threads weren't threads, really. JAD: Well, okay. JENNFER FRAZER: Well, they do it because the tree has something the fungus needs, and the fungus has something the tree needs. Yeah. I don't know yet. ALVIN UBELL: If you look at a root under a microscope, what you see is all these thousands of feelers like hairs on your head looking for water. . And Jigs at some point just runs off into the woods, just maybe to chase a rabbit. So I'd seal the plant, the tree in a plastic bag, and then I would inject gas, so tagged with a -- with an isotope, which is radioactive. And the tree happens to be a weeping willow. JENNIFER FRAZER: Well, maybe. But if you dig a little deeper, there's a hidden world beneath your feet as busy and complicated as a city at rush hour. 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. The fungi, you know, after it's rained and snowed and the carcass has seeped down into the soil a bit, the fungi then go and they drink the salmon carcass down and then send it off to the tree. Couldn't it just be an entirely different interpretation here? ROBERT: 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? Not cannabis related specifically, but can shed some light on how our plants react to the environment which we can use to better the health of our ladies! Like a human would. Once you understand that the trees are all connected to each other, they're all signaling each other, sending food and resources to each other, it has the feel, the flavor, of something very similar. Two very different options for our plant. If you get too wrapped up in your poetic metaphor, you're very likely to be misled and to over-interpret the data. ROBERT: Is your dog objecting to my analysis? No question there. ROBERT: She determined that you can pick a little computer fan and blow it on a pea plant for pretty much ever and the pea plant would be utterly indifferent to the whole thing. Inspector Tail is his name. MONICA GAGLIANO: Yeah, tested it in my lab. To remember? We went to the Bronx, and when we went up there, we -- there was this tall man waiting for us. For this part of our broadcast, I'd like to begin by imagining a tall, dark, dense, green forest. Like so -- and I think that, you know, the whole forest then, there's an intelligence there that's beyond just the species. JAD: The thing I don't get is in animals, the hairs in our ear are sending the signals to a brain and that is what chooses what to do. This -- this actually happened to me. Couple minutes go by And all of a sudden we could hear this barking and yelping. And for the meat substitute, she gave each plant little bit of food. I don't want that.". Does it threaten my sense of myself or my place as a human that a plant can do this? They somehow have a dye, and don't ask me how they know this or how they figured it out, but they have a little stain that they can put on the springtails to tell if they're alive or dead. We are the principals of Accurate Building Inspectors of Brooklyn, New York. Well, maybe. And he starts digging with his rake at the base of this tree. ROBERT: And the classic case of this is if you go back a few centuries ago, someone noticed that plants have sex. They may have this intelligence, maybe we're just not smart enough yet to figure it out. Again. The bell, the meat and the salivation. Except in this case instead of a chair, they've got a little plant-sized box. If you look at these particles under the microscope, you can see the little tunnels. Of Accurate Building Inspectors. If there was only the fan, would the plant After three days of this training regime, it is now time to test the plants with just the fan, no light. JAD: Is it just pulling it from the soil? JAD: Yeah, absolutely. ALVIN UBELL: You have to understand that the cold water pipe causes even a small amount of water to condense on the pipe itself. They still did not close when she dropped them. With when they actually saw and smelled and ate meat. So after much trial and error with click and hums and buzzes She found that the one stimulus that would be perfect was A little fan. Pretty much like the concept of Pavlov with his dog applied. JENNIFER FRAZER: Yeah. I know -- I know you -- I know you don't. MONICA GAGLIANO: It's a very biased view that humans have in particular towards others. You know, one of those little jeweler's glasses? You know, it goes back to anthropomorphizing plant behaviors. No. I wonder if that was maybe a bit too much. And she says this time they relaxed almost immediately. They're switched on. And I met a plant biologist who's gonna lead that parade. 37:51. ROBERT: Had indeed turned and moved toward the fan, stretching up their little leaves as if they were sure that at any moment now light would arrive. And therefore she might, in the end, see something that no one else would see. So they might remember even for a much longer time than 28 days. And might as well start the story back when she was a little girl. Fan first, light after. That's what she says. So today we have a triptych of experiments about plants. 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. MONICA GAGLIANO: Yeah, I know. Can you make your own food? Oh, yeah. She says we now know that trees give each other loans. 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. So that's where these -- the scientists from Princeton come in: Peter, Sharon and Aatish. MONICA GAGLIANO: All of them know already what to do. Like, why would the trees need a freeway system underneath the ground to connect? Radiolab - Smarty Plants . Like, the plant is hunting? JAD: Where would the -- a little plant even store a memory? Jad and Robert, they are split on this one. Or even learn? And does it change my place in the world? Which by the way, is definitely not a plant. So there's these little insects that lives in the soil, these just adorable little creatures called springtails. She made sure that the dirt didn't get wet, because she'd actually fastened the water pipe to the outside of the pot. I mean, you're out there in the forest and you see all these trees, and you think they're individuals just like animals, right? Like trees of different species are supposed to fight each other for sunshine, right? She's done three experiments, and I think if I tell you about what she has done, you -- even you -- will be provoked into thinking that plants can do stuff you didn't imagine, dream they could do. Can you -- will you soften your roots so that I can invade your root system?" There's not a leak in the glass. LINCOLN TAIZ: I think you can be open-minded but still objective. Exactly. Exactly. And every day that goes by, I have less of an issue from the day before. Like, from the trees perspective, how much of their sugar are they giving to the fungus? Can the tree feel you ripping the roots out like that? 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. ROBERT: And the idea was, she wanted to know like, once the radioactive particles were in the tree, what happens next? JAD: What -- I forgot to ask you something important. Like, as in the fish. ROBERT: That's a -- learning is something I didn't think plants could do. So, okay. He was a -- what was he? So she's saying they remembered for almost a month? Except in this case instead of a chair, they've got a little plant-sized box. And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. SUZANNE SIMARD: And there was a lot of skepticism at the time. So actually, I think you were very successful with your experiment. Wait. It's kind of like a cold glass sitting on your desk, and there's always a puddle at the bottom. So they figured out who paid for the murder. If a plant doesn't have a brain what is choosing where to go? From just bears throwing fish on the ground? If the -- if the tube system is giving the trees the minerals, how is it getting it, the minerals? Connecting your house to the main city water line that's in the middle of the street. But it was originally done with -- with a dog. He uses it to train his border www.npr.org Before you begin to think that this is weird science, stop. I mean, it's a kind of romanticism, I think. Then we actually had to run four months of trials to make sure that, you know, that what we were seeing was not one pea doing it or two peas, but it was actually a majority.
