ALVIN UBELL: How much longer? No, so for example, lignin is important for making a tree stand up straight. MONICA GAGLIANO: Yeah, mimosa has been one of the pet plants, I guess, for many scientists for, like, centuries. And the pea plant leans toward them. Maybe not with the helmet, but yeah. That's the place where I remember things. Two very different options for our plant. ], This is Jennifer Frazer, and I'm a freelance science writer and blogger of The Artful Amoeba at Scientific American. ROBERT: That would be sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals. [laughs]. I guess you could call it a mimosa plant drop box. Yeah. It spits out the O2. What was your reaction when you saw this happen? And it's good it was Sunday. I thought okay, so this is just stupid. Oh. ROBERT: Yeah. It's a very interesting experiment, and I really want to see whether it's correct or not. It was like -- it was like a huge network. MONICA GAGLIANO: I wonder if that was maybe a bit too much. But also SUZANNE SIMARD: The other important thing we figured out is that, as those trees are injured and dying, they'll dump their carbon into their neighbors. Birds. On the outside of the pipe. So he brought them some meat. Okay? So today we have a triptych of experiments about plants. He was a -- what was he? LARRY UBELL: Or it's just the vibration of the pipe that's making it go toward it. Unfortunately, right at that point Suzanne basically ran off to another meeting. 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. Then he would bring them the meat and he would ring a bell. What do you mean? JENNIFER FRAZER: This all has a history, of course. ROBERT: They would salivate and then eat the meat. Yes, we are related. They don't do well in warm temperatures and their needles turn all sickly yellow. It's like every time I close my eyes, you're coming at it from a different direction. Peering down at the plants under the red glow of her headlamp. MONICA GAGLIANO: Yeah. This is like metaphor is letting in the light as opposed to shutting down the blinds. Let him talk. And so I was really excited. No, I actually, like even this morning it's already like poof! But it was originally done with -- with a dog. MONICA GAGLIANO: So, you know, I'm in the dark. Into which she put these sensitive plants. Science writer Jen Frazer gave us kind of the standard story. It's like, no, no, I don't do that. JAD: So she's saying they remembered for almost a month? No, no, no, no, no. ROBERT: This happens to a lot of people. ROBERT: So the beetles don't want to eat them. And so I was really excited. They start producing chemicals that taste really bad. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. That there was a kind of a moral objection to thinking this way. I don't know where you were that day. ROBERT: So what they're saying is even if she's totally sealed the pipe so there's no leak at all, the difference in temperature will create some condensation on the outside. And then I would cover them in plastic bags. But it didn't happen. And we can move it up, and we can drop it. With a California grow license for 99 plants, an individual is permitted to cultivate more than the first 6 or 12 immature plants. [ANSWERING MACHINE: To play the message, press two. I was like, "Oh, my God! ROY HALLING: Well, you can see the white stuff is the fungus. Well, I asked Suzanne about that. JENNIFER FRAZER: But no, they're all linked to each other! 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. He'd fallen in. And then I needed to -- the difficulty I guess, of the experiment was to find something that will be quite irrelevant and really meant nothing to the plant to start with. All right, that's it, I think. Like for example, my plants were all in environment-controlled rooms, which is not a minor detail. Jigs is in trouble!" Wait a second. ROBERT: And she says she began to notice things that, you know, one wouldn't really expect. They're switched on. So she's saying they remembered for almost a month? ROBERT: That there was a kind of a moral objection to thinking this way. So otherwise they can't photosynthesize. Finally, one time he did not bring the meat, but he rang the bell. Not really. I mean, Jigs was part of the family. ]. JENNIFER FRAZER: If you look at these particles under the microscope, you can see the little tunnels. St. Andrew's Magazine Dr. Aatish Bhatia Inspires Students & Faculty. Now, can you -- can you imagine what we did wrong? That would be sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals-sugar-minerals. So the -- this branching pot thing. PETER LANDGREN: Little seatbelt for him for the ride down. I don't know. More information about Sloan at www.sloan.org]. No question there. I think you can be open-minded but still objective. And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. There are multiple ways of doing one thing, right? She thinks that they somehow remembered all those drops and it never hurt, so they didn't fold up any more. MONICA GAGLIANO: My reaction was, "Oh ****!" So we're up to experiment two now, are we not? ROBERT: And not too far away from this tree, underground, there is a water pipe. It was like, Oh, I might disturb my plants!" 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.". 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. MONICA GAGLIANO: Like a defensive mechanism. JAD: Where would the -- a little plant even store a memory? Maybe not with the helmet, but yeah. Yes. ], [ROY HALLING: Jamie York is our Senior Producer. Ring, meat, eat. JENNIFER FRAZER: So Pavlov started by getting some dogs and some meat and a bell. And again. Turns the fan on, turns the light on, and the plant turns and leans that way. It was summertime. 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. On our knees with our noses in the ground, and we can't see anything. No. And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. ROBERT: She made sure that the dirt didn't get wet, because she'd actually fastened the water pipe to the outside of the pot. RICHARD ATTENBOROUGH: It's the equivalent of a human being jumping over the Eiffel Tower. 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. ROBERT: What do you mean? Maybe there's some kind of signal? It's the equivalent of a human being jumping over the Eiffel Tower. Into the roots, and then into the microbial community, which includes the mushroom team, yeah. In 1997, a couple of scientists wrote a paper which describes how fungi JENNIFER FRAZER: Have developed a system for mining. Ring, meat, eat. It's just getting started. ], [JENNIFER FRAZER: Dylan Keefe is our Director of Sound Design. Jennifer told Latif and I about another role that these fungi play. He's the only springtail with a trench coat and a fedora. Like, how can a plant -- how does a plant do that? Jad and Robert, they are spli JENNIFER FRAZER: But we don't know. And she says she began to notice things that, you know, one wouldn't really expect. There was a healthier community when they were mixed and I wanted to figure out why. Little fan goes on, the light goes on. They definitely don't have a brain. Monica thought about that and designed a different experiment. It seems like a no-brainer to me (pardon the unintentional pun) that they would have some very different ways of doing things similar to what animals do. Can Robert get Jad to join the march? The water is still in there. [laughs]. 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. Except in this case instead of a chair, they've got a little plant-sized box. MONICA GAGLIANO: Well, I created these horrible contraptions. I mean, I -- it's a kind of Romanticism, I think. JAD: The part where the water pipe was, the pipe was on the outside of the pot? 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. In 1997, a couple of scientists wrote a paper which describes how fungi Jennifer says that what the tubes do is they worm their way back and forth through the soil until they bump into some pebbles. ROBERT: And she goes into that darkened room with all the pea plants. Never mind.". And it's that little, little bit of moisture that the plant will somehow sense. A plant that is quite far away from the actual pipe. All in all, turns out one tree was connected to 47 other trees all around it. JENNIFER FRAZER: Oh, yeah. Anyone who's ever had a plant in a window knows that. But the drop was just shocking and sudden enough for the little plant to Do its reflex defense thing. Robert, I have -- you know what? So maybe could you just describe it just briefly just what you did? MONICA GAGLIANO: Yeah. ROBERT: Now, you might think that the plant sends out roots in every direction. The next one goes, "Uh-oh." ROBERT: And the classic case of this is if you go back a few centuries ago, someone noticed that plants have sex. And the tree gets the message, and it sends a message back and says, "Yeah, I can do that.". 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? I've been looking around lately, and I know that intelligence is not unique to humans. It's a family business. JENNIFER FRAZER: They're called springtails, because a lot of them have a little organ on the back that they actually can kind of like deploy and suddenly -- boing! But instead of dogs, she had pea plants in a dark room. ROBERT: To try to calculate how much springtail nitrogen is traveling back to the tree. All right, that's it, I think. JENNIFER FRAZER: Well, maybe. They still remembered. No, Summer is a real person and her last name happens to be spelled R-A-Y-N-E. ROBERT: This story was nurtured and fed and ultimately produced by Annie McEwen. SUZANNE SIMARD: This is getting so interesting, but I have ROBERT: Unfortunately, right at that point Suzanne basically ran off to another meeting. He was a -- what was he? So she decided to conduct her experiment. Now, can you -- can you imagine what we did wrong? All right, my hypothesis is that what happens is You got somewhere to go? 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. MONICA GAGLIANO: I don't know. We went to the Bronx, and when we went up there, we -- there was this tall man waiting for us. But now we know, after having looked at their DNA, that fungi are actually very closely related to animals. I guess you could call it a mimosa plant drop box. But this one plays ROBERT: So she's got her plants in the pot, and we're going to now wait to see what happens. Yeah. Yes, because she knew that scientists had proposed years before, that maybe there's an underground economy that exists among trees that we can't see. She says we now know that trees give each other loans. ROBERT: She took that notion out of the garden into her laboratory. Actually, Monica's dog leads perfectly into her third experiment, which again will be with a plant. ROBERT: So after much trial and error with click and hums and buzzes MONICA GAGLIANO: All sorts of randomness. ROBERT: And right in the middle of the yard is a tree. JAD: Where would the -- a little plant even store a memory? It would be all random. JENNIFER FRAZER: These little soil particles. I don't know yet. I thought -- I thought tree roots just sort of did -- like, I thought -- I always imagined tree roots were kind of like straws. This is not so good" signal through the network. I go out and I thought there's no one here on Sunday afternoon. The light and the fan were always coming from the same direction. Then she takes the little light and the little fan and moves them to the other side of the plant. It's like a savings account? ROBERT: I wanted to talk to them because, as building inspectors they -- there's something they see over and over and over. But the Ubells have noticed that even if a tree is 10 or 20, 30 yards away from the water pipe, for some reason the tree roots creep with uncanny regularity straight toward the water pipe. It's an integral part of DNA. This -- this actually happened to me. I'm a research associate professor at the University of Sydney. ROBERT: She says it was like this moment where she realizes, "Oh, my God! And, you know, my job was to track how these new plantations would grow. And it begins to look a lot like an airline flight map, but even more dense. Oh, so it says to the newer, the healthier trees, "Here's my food. And so the whole family and uncles and aunts and cousins, we all rush up there. And for the meat substitute, she gave each plant little bit of food. In this case, a little blue LED light. But they do have root hairs. The part where the water pipe was, the pipe was on the outside of the pot? ROBERT: But that scientist I mentioned MONICA GAGLIANO: My name is Monica Gagliano. So I don't have a problem. But what -- how would a plant hear something? And look, and beyond that there are forests, there are trees that the scientists have found where up to 75 percent of the nitrogen in the tree turns out to be fish food. JENNIFER FRAZER: Finally, one time he did not bring the meat, but he rang the bell. JAD: Are you bringing the plant parade again? ROBERT: And we saw this in the Bronx. It's condensation. 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. Have you hugged your houseplant today? No boink anymore. Does it threaten my sense of myself or my place as a human that a plant can do this? Because after dropping them 60 times, she then shook them left to right and they instantly folded up again. JAD: So we're up to experiment two now, are we not? LARRY UBELL: We are the principals of Accurate Building Inspectors of Brooklyn, New York. So we are going to meet a beautiful little plant called a mimosa pudica, which is a perfectly symmetrical plant with leaves on either side of a central stem. I don't think Monica knows the answer to that, but she does believe that, you know, that we humans We are a little obsessed with the brain. And then they do stuff. We waiting for the leaves to, you know, stop folding. LARRY UBELL: It's not leaking. If I want to be a healthy tree and reach for the sky, then I need -- I need rocks in me somehow. Our store also offers Grooming, Training, Adoptions, Veterinary and Curbside Pickup. It's okay. MONICA GAGLIANO: So, you know, I'm in the dark. It's like, no, no, I don't do that. And so we're digging away, and Jigs was, you know, looking up with his paws, you know, and looking at us, waiting. Like, the tree was, like, already doing that stuff by itself, but it's the fungus that's doing that stuff? And so on. Again. Enough of that! Then Monica hoists the plant back up again and drops it again. Or even learn? JAD: Would you say that the plant is seeing the sun? ROBERT: And some of them, this is Lincoln Taiz LINCOLN TAIZ: I'm a professor emeritus of plant biology at UC Santa Cruz. They stopped folding up. Seasonally. And therefore she might, in the end, see something that no one else would see. So let's go to the first. What was your reaction when you saw this happen? Promote. I think there are some cases where romanticizing something could possibly lead you to some interesting results. MONICA GAGLIANO: Picasso! The water is still in there. But what I do know is that the fact that the plant doesn't have a brain doesn't -- doesn't a priori says that the plants can't do something. So, okay. So maybe the root hairs, which are always found right at the growing tips of plant roots, maybe plant roots are like little ears. What -- I forgot to ask you something important. And Roy by the way, comes out with this strange -- it's like a rake. JAD: Are you bringing the plant parade again? Truth is, I think on this point she's got a -- she's right. ROBERT: Oh, so it says to the newer, the healthier trees, "Here's my food. Okay.

Because the only reason why the experiment turned out to be 28 days is because I ran out of time. And a little wind. I found a little water! And so on. LARRY UBELL: Or it's just the vibration of the pipe that's making it go toward it. ROBERT: So that voice belongs to Aatish Bhatia, who is with Princeton University's Council on Science and Technology. I gotta say, doing this story, this is the part that knocked me silly. Tagged #science #technology #philosophy #education #radiolab. We went and looked for ourselves. I go out and I thought there's no one here on Sunday afternoon. And then I needed to -- the difficulty I guess, of the experiment was to find something that will be quite irrelevant and really meant nothing to the plant to start with. But over the next two decades, we did experiment after experiment after experiment that verified that story. But no, they're all linked to each other! You need the nutrients that are in the soil. MONICA GAGLIANO: Picasso! SUZANNE SIMARD: When I was a little kid, I would be in the forest and I'd just eat the forest floor. ALVIN UBELL: They would have to have some ROBERT: Maybe there's some kind of signal? So what do we have in our ears that we use to hear sound? ROBERT: Jennifer says that what the tubes do is they worm their way back and forth through the soil until they bump into some pebbles. Is your dog objecting to my analysis? They're called feeder roots. They definitely don't have a brain. ROBERT: Smaller than an eyelash. ROBERT: Eventually, she came back after ROBERT: And they still remembered. ALVIN UBELL: And the tree happens to be a weeping willow. And then she waited a few more days and came back. MONICA GAGLIANO: It's a very biased view that humans have in particular towards others. ], [ALVIN UBELL: Maria Mata -- Maria Matasar ], [LARRY UBELL: Maria Matasar-Padilla is our Managing Director.
