radiolab smarty plants

That's amazing and fantastic. Huh. I mean, it's just -- it's reacting to things and there's a series of mechanical behaviors inside the plant that are just bending it in the direction. It's yours." 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. Why is this network even there? JAD: The part where the water pipe was, the pipe was on the outside of the pot? One time, the plant literally flew out of the pot and upended with roots exposed. Except in this case instead of a chair, they've got a little plant-sized box. JENNIFER FRAZER: Well, 25 percent of it ended up in the tree. I'm gonna just go there. We had a Geiger counter out there. Like, can a tree stand up straight without minerals? JENNIFER FRAZER: The fungi needs sugar to build their bodies, the same way that we use our food to build our bodies. We ask deep questions and use investigative journalism to get the answers. 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. And might as well start the story back when she was a little girl. Smarty Plants. 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. It's like a savings account? Jad and Robert, theyare split on this one. That is actually a clue in what turns out to be a deep, deep mystery. So, okay. Yeah, mimosa has been one of the pet plants, I guess, for many scientists for, like, centuries. A given episode might whirl you through science, legal history, and into the home of someone halfway across the world. And we can move it up, and we can drop it. Again. Just for example. JAD: But still. Why is this network even there? And she says she began to notice things that, you know, one wouldn't really expect. ROBERT: And I met a plant biologist who's gonna lead that parade. Radiolab is supported in part by the Alfred P. Sloan Foundation, enhancing public understanding of science and technology in the modern world. ROBERT: But what -- how would a plant hear something? But then, scientists did an experiment where they gave some springtails some fungus to eat. Well, it depends on who you ask. Pretty much like the concept of Pavlov with his dog applied. They definitely don't have a brain. Science writer Jen Frazer gave us kind of the standard story. ROBERT: The plants would always grow towards the light. JENNIFER FRAZER: Right? But when we look at the below ground structure, it looks so much like a brain physically, and now that we're starting to understand how it works, we're going, wow, there's so many parallels. I found a little water! ROBERT: And some of them, this is Lincoln Taiz LINCOLN TAIZ: I'm a professor emeritus of plant biology at UC Santa Cruz. I was, like, floored. MONICA GAGLIANO: Yeah, I know. LARRY UBELL: I'm not giving my age. SUZANNE SIMARD: Into the roots, and then into the microbial community, which includes the mushroom team, yeah. They will send out a "Oh, no! Have you hugged your houseplant today? And again. Is your dog objecting to my analysis? It's time -- time for us to go and lie down on the soft forest floor. Again. Just the sound of it? No matter how amazing I think that the results are, for some reason people just don't think plants are interesting. ROBERT: Yeah. ALVIN UBELL: They would have to have some ROBERT: Maybe there's some kind of signal? So you -- if you would take away the fish, the trees would be, like, blitzed. The fungus is hunting. Or maybe slower? No question there. And Roy by the way, comes out with this strange -- it's like a rake. ROBERT: How do you mean? SUZANNE SIMARD: Not a basset hound, but he was a beagle. Every one of them. Because I have an appointment. This is the plant and pipe mystery. It's almost as if the forest is acting as an organism itself. And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. Is that what -- is that what this? MONICA GAGLIANO: Yeah. And for the meat substitute, she gave each plant little bit of food. Or at the time actually, she was a very little girl who loved the outdoors. I go out and I thought there's no one here on Sunday afternoon. Thanks to Jennifer Frazer who helped us make sense of all this. ROBERT: Oh, so this is, like, crucial. It just kept curling and curling. ROBERT: What do you mean? SUZANNE SIMARD: We had a Geiger counter out there. So you can -- you can see this is like a game of telephone. So these trees were basically covered with bags that were then filled with radioactive gas. So I think what she would argue is that we kind of proved her point. Can you make your own food? ROBERT: But then, scientists did an experiment where they gave some springtails some fungus to eat. Because after dropping them 60 times, she then shook them left to right and they instantly folded up again. I mean, couldn't it just be like that? ROBERT: Oh, hunting for water. This is the plant and pipe mystery. Birds. LARRY UBELL: It's not leaking. But it didn't happen. It's a -- it's a three-pronged answer. It doesn't ROBERT: I know, I know. So that's what the tree gives the fungus. I mean, I see the dirt. JENNIFER FRAZER: I am the blogger of The Artful Amoeba at Scientific American. I don't know if that was the case for your plants. MONICA GAGLIANO: Yeah, plants really like light, you know? 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. You have to understand that the cold water pipe causes even a small amount of water to condense on the pipe itself. What the team found is the food ends up very often with trees that are new in the forest and better at surviving global warming. If you get too wrapped up in your poetic metaphor, you're very likely to be misled and to over-interpret the data. You got the plant to associate the fan with food. So we went back to Monica. ROBERT: She found that the one stimulus that would be perfect was MONICA GAGLIANO: A little fan. I know. JENNIFER FRAZER: With when they actually saw and smelled and ate meat. ROBERT: And right in the middle of the yard is a tree. And Basically expanding it from a kind of a column of a pit to something that's -- we could actually grab onto his front legs and pull him out. They would salivate and then eat the meat. They're some other kind of category. Turns the fan on, turns the light on, and the plant turns and leans that way. But they do have root hairs. So its resources, its legacy will move into the mycorrhizal network into neighboring trees. ROBERT: To try to calculate how much springtail nitrogen is traveling back to the tree. ROBERT: But she's got a little red headlamp on. JAD: You're doing the -- like, okay first it was the roots under the ground all connected into a whole hive thing. But now we know, after having looked at their DNA, that fungi are actually very closely related to animals. ROBERT: So you're like a metaphor cop with a melty heart. 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. And it was almost like, let's see how much I have to stretch it here before you forget. You give me -- like, I want wind, birds, chipmunks Like, I'm not, like, your sound puppet here. JENNIFER FRAZER: Well, maybe. So we're up to experiment two now, are we not? Monica thought about that and designed a different experiment. SUZANNE SIMARD: Potassium and calcium and ROBERT: Like, can a tree stand up straight without minerals? ROBERT: Begins with a woman. But let me just -- let me give it a try. And then when times are hard, that fungi will give me my sugar back and I can start growing again. So he brought them some meat. ROBERT: He's got lots of questions about her research methods, but really his major complaint is -- is her language. He's got lots of questions about her research methods, but really his major complaint is -- is her language. ], [JENNIFER FRAZER: This is Jennifer Frazer, and I'm a freelance science writer and blogger of The Artful Amoeba at Scientific American. Well, when I was a kid, my family spent every summer in the forest. Fan, light, lean. And they still remembered. They definitely don't have a brain. I don't know if that was the case for your plants. But she had a kind of, maybe call it a Jigs-ian recollection. It's like a bank? That's what she says. JENNIFER FRAZER: Anyone who's ever had a plant in a window knows that. JAD: Yes. Princeton University News Transformations: Students find creativity at intersection of art and engineering. They shade each other out. JENNIFER FRAZER: They're some other kind of category. 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. 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. And we were all like, "Oh, my goodness! But still. And if you go to too many rock concerts, you can break these hairs and that leads to permanent hearing loss, which is bad. "I'm under attack!". So, okay. Like trees of different species are supposed to fight each other for sunshine, right? JENNIFER FRAZER: Apparently she built some sort of apparatus. 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. They can go north, south, east, west, whatever. But after five days, she found that 80% of the time, the plants went -- or maybe chose -- to head toward the dry pipe that has water in it. Oh. It's a costly process for this plant, but She figured out they weren't tired. The water is still in there. But maybe it makes her sort of more open-minded than -- than someone who's just looking at a notebook. 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. Me first. That was my reaction. I don't know why you have problems with this. It spits out the O2. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. I found a little water! Well, it depends on who you ask. ROBERT: And the salivation equivalent was the tilt of the plant? I mean, you've heard that. MONICA GAGLIANO: I don't know. JAD: Yeah, absolutely. Eventually over a period of time, it'll crack the pipe like a nutcracker. I mean, what? There's not a leak in the glass. No. If she's going to do this experiment, most likely she's going to use cold water. JENNIFER FRAZER: With when they actually saw and smelled and ate meat. JENNIFER FRAZER: This all has a history, of course. And what a tree needs are minerals. Because I have an appointment. ROBERT: So that voice belongs to Aatish Bhatia, who is with Princeton University's Council on Science and Technology. Me first. So he brought them some meat. Yeah. MONICA GAGLIANO: A plant that is quite far away from the actual pipe. And there was a lot of skepticism at the time. These guys are actually doing it." MONICA GAGLIANO: Landing very comfortably onto a padded base made of foam. ROBERT: 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. And not too far away from this tree, underground, there is a water pipe. ROBERT: So now, they had the radioactive particles inside their trunks and their branches. ROBERT: And some of them, this is Lincoln Taiz LINCOLN TAIZ: I'm a professor emeritus of plant biology at UC Santa Cruz. Wait a second. MONICA GAGLIANO: Again, if you imagine that the pot, my experimental pot. You know, they talk about how honeybee colonies are sort of superorganisms, because each individual bee is sort of acting like it's a cell in a larger body. So the fungus is giving the tree the minerals. Like for example, my plants were all in environment-controlled rooms, which is not a minor detail. And it's good it was Sunday. ROBERT: And that's just the beginning. So they didn't. They're switched on. No, so for example, lignin is important for making a tree stand up straight. 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? You need the nutrients that are in the soil. ALVIN UBELL: Testing one, two. ROBERT: All right, that's it, I think. And then all the other ones go in the same direction. Because after dropping them 60 times, she then shook them left to right and they instantly folded up again. And so we are under the impression or I would say the conviction that the brain is the center of the universe, and -- and if you have a brain and a nervous system you are good and you can do amazing stuff. Gone. Of Accurate Building Inspectors. ROBERT: Packets of minerals. Pics! ], [ROY HALLING: Radiolab is produced by Jad Abumrad. Or at the time actually, she was a very little girl who loved the outdoors. The plants would always grow towards the light. What do mean, the fungi will give me my sugar back? On the fifth day, they take a look and discover most of the roots, a majority of the roots were heading toward the sound of water. 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. It's a very interesting experiment, and I really want to see whether it's correct or not. MONICA GAGLIANO: Yeah. 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 so of course, that was only the beginning. It's like a savings account? Fan first, light after. And with these two stimuli, she put the plants, the little pea plants through a kind of training regime. I know -- I know you -- I know you don't. And the -- I'm gonna mix metaphors here, the webs it weaves. MONICA GAGLIANO: So, you know, I'm in the dark. If a plant doesn't have a brain what is choosing where to go? And I remember it was Sunday, because I started screaming in my lab. He was a -- what was he? PETER LANDGREN: Little seatbelt for him for the ride down. JENNIFER FRAZER: Yeah, it might run out of fuel. Nothing delicious at all. ROBERT: So light is -- if you shine light on a plant you're, like, feeding it? And then someone has to count. LARRY UBELL: I'm not giving my age. 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. I can scream my head off if I want to. 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. So the plants are now, you know, buckled in, minding their own business. Yes. Or even learn? JAD: That apparently -- jury's still out -- are going to make me rethink my stance on plants. ROBERT: This happens to a lot of people. 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. ]. Our store also offers Grooming, Training, Adoptions, Veterinary and Curbside Pickup. That's okay. I don't know yet. And if you don't have one, by default you can't do much in general. 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. ROBERT: It won't be a metaphor in just a moment. So she takes the plants, she puts them into the parachute drop, she drops them. Ring, meat, eat. ROBERT: And so now we're down there. They're not experiencing extra changes, for example. ROBERT: Ring, meat, eat. Let him talk. And I remember it was Sunday, because I started screaming in my lab. SUZANNE SIMARD: Yeah, he was a curious dog. It's gone. ROBERT: Yeah. It would be all random. They can't take up CO2. JENNIFER FRAZER: The whole thing immediately closes up and makes it look like, "Oh, there's no plant here. This peculiar plant has a -- has a surprising little skill. We're just learning about them now, and they're so interesting. 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. No question there. And then what happens? So ROBERT: He says something about that's the wrong season. I don't want that.". The glass is not broken. Testing one, two. And the idea was, she wanted to know like, once the radioactive particles were in the tree, what happens next? 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. It was like -- it was like a huge network. But instead of dogs, she had pea plants in a dark room. 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 you're like a metaphor cop with a melty heart. My reaction was like, "Oh ****!" ROBERT: I'm not gonna tell you. MONICA GAGLIANO: The idea was to drop them again just to see, like, the difference between the first time you learn something and the next time. But let me just -- let me give it a try. 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. Exactly. You just used a very interesting word. ROBERT: So the roots can go either left or to the 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. And then Monica would Just about, you know, seven or eight inches. Each one an ounce, an ounce, an ounce, an ounce, an ounce. ], Test the outer edges of what you think you know. ROBERT: So the plants are now, you know, buckled in, minding their own business. JAD: So they just went right for the MP3 fake water, not even the actual water? I'm a research associate professor at the University of Sydney. She thinks that they somehow remembered all those drops and it never hurt, so they didn't fold up any more. The light and the fan were always coming from the same direction. I'm not making this up. That's the place where I remember things. LARRY UBELL: That -- that's -- that's interesting. It's a very biased view that humans have in particular towards others. I remember going in at the uni on a Sunday afternoon. ROBERT: I have even -- I can go better than even that. And the pea plant leans toward them. Yeah. This happens to a lot of people. Never mind. 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. There was some kind of benefit from the birch to the fur. I mean, I -- it's a kind of Romanticism, I think. And now, if you fast-forward roughly 30 years, she then makes a discovery that I find kind of amazing. Begins with a woman. It was like, "Oh, I might disturb my plants!" He shoves away the leaves, he shoves away the topsoil. ], [LARRY UBELL: Radiolab was created by Jad Abumrad and is produced by Soren Wheeler. Apparently, bears park themselves in places and grab fish out of the water, and then, you know, take a bite and then throw the carcass down on the ground. I've always loved Radiolab. Because what she does next is three days later, she takes these plants back into the lab. So that's where these -- the scientists from Princeton come in: Peter, Sharon and Aatish. Can you -- will you soften your roots so that I can invade your root system?" I was like, "Oh, my God! She's not gonna use hot water because you don't want to cook your plants, you know? And then they do stuff. I don't know. You got the plant to associate the fan with food. JENNIFER FRAZER: Carbon, which is science speak for food. On the fifth day, they take a look and discover most of the roots, a majority of the roots were heading toward the sound of water. What the team found is the food ends up very often with trees that are new in the forest and better at surviving global warming. However, if that's all they had was carbon That's Roy again. It should have some. It's 10 o'clock and I have to go. Testing one, two. Do you have the lens? Thanks to Jennifer Frazer who helped us make sense of all this. One of the spookiest examples of this Suzanne mentioned, is an experiment that she and her team did where they discovered that if a forest is warming up, which is happening all over the world, temperatures are rising, you have trees in this forest that are hurting. ROBERT: Absolutely not. The fungi needs sugar to build their bodies, the same way that we use our food to build our bodies.
