Meet the Lab Girl.

What do you see when you look into a lab? Fluorescent lights and whirring machinery? Gee-whiz equipment and tempting red buttons?…By Michael Segal

What do you see when you look into a lab? Fluorescent lights and whirring machinery? Gee-whiz equipment and tempting red buttons? Hope Jahren, the geochemist and geobiologist, sees those things, certainly, but also something else: Home. “It just feels to me like the most wonderful, softest, warmest, safest place in the world,” she says in her Nautilus interview.

Jahren is an accomplished scientist and a tenured professor at the University of Hawai’i at Mānoa in Honolulu. She has received three Fulbright Awards in geobiology, and is the only woman to have been awarded both of the Young Investigator Medals given in the earth sciences. In 2005, Popular Science christened her one of the “Brilliant 10” young scientists.

With her upcoming book, Lab Girl, she shows us that she is also one of today’s best popular science writers. Her book explores the confluence of science, identity, and belonging that has run through her career, and invites us to share in the scientist’s joy of play, feeling of community, and wonder, all of which are vivid and intact on the page.

The language of her book, as Jahren explains in her interview, is the result of a kind of scientific process, each sentence considered and re-considered. She applies this same precision to her thinking about science as an institution, the role of women in science, science education, and, of course, her true love: plants.

Nautilus caught up with Jahren at her home in Hawai’i.

The Lessons of a Ghost Planet

Sometime between November 11 and 18, 1915, Albert Einstein began a brief calculation. In 14 numbered steps he analyzed the orbit of Mercury to explain a minor anomaly that had defied astronomers for more than 50 years. Sorting out a...READ MORE

Interview Transcript

How has your science changed your view of the world?

Personally I think that’s the true purpose of science. In that it’s not to build bridges or make new combat-lack-of-erection medicines. It’s to feed the soul in the same way that art is. The more you know about the world, the more you feel like you’re part of it. And that’s the purpose of teaching it to children and to girls. Once you spend time that way you see the world differently, and that’s another thing I’ve really tried to bring out in my book. I use all the time I’ve spent sorting things and labeling things and manipulating things—it’s got into me, it’s soaked into me all the way into my heart and up into my brain, and it changes the way I see the world. That’s something that I really love about myself and I love about my life. And I want to share that.

Something that comes to me many times a day, that I’m sure comes to me because of the scientific tasks I’ve performed for so many years, is the difference between staying and going. I think that’s the fundamental difference between a plant and an animal, is that if an animal doesn’t like where it is, it can get up and move away. Plants have to stay there and take it. There are a lot of other differences between plants and animals of course, but I believe that seeps into everything about how different they are and I believe that I can look around me and see the things that stay. Better than a person who hasn’t devoted themselves to the same activities I have. I believe I know things about what it means to stay and endure and watch and grow. And I wouldn’t trade that for any other life. If everything I’ve done only brought that to me, if that was the only reward for everything I’ve done, then it would be worth it a hundred times over. You can do it too you know, look around you and think about the things that stay. And when you walk away, they’ll still be there and night will fall and rain will fall and the snow will melt and … in your mind you can inhabit another life and that’s the ultimate transcendence of yourself.

Being in a laboratory was always just the most wonderful, comforting, familiar, happy, safe place.

Why is your relationship with science so personal?

I believe that science is practiced in the home first and foremost. That it’s a way of seeing things and a way of doing things, right down to the way you sew, the way you cook, the way you measure the window to buy curtains. I saw my mother do those things, wait, I saw my father do those things in the laboratory where he taught at a community college for 42 consecutive years. He taught science, all sciences, in a laboratory in a rural community college. And I saw my mother do that at home in everything she did. She optimized everything she did for efficiency and the quality of execution. And so I saw those behaviors as very deeply rooted in the way you think, the way you approach all the materials around you, and that’s where I feel most comfortable. That’s where I learned to interact with the world as a child, and that’s the way I live now.

So when I’m doing science, when I’m manipulating things with my hands or measuring things or analyzing patterns, that’s when I’m most me. That’s when I’m most still in contact with the person that I knew I was as a child and the person that I am that has always stayed with me. It is very deeply in my identity and you know regardless of what my job title is or who is employing me to do these activities or what people think of how I do them—that’s all secondary to living it out with my hands and with my eyes and with the people in my life who get it.

I have three older brothers and we went to my father’s laboratory in the evenings after school and we played in the laboratory while he graded or set things up for the next day or repaired the demonstrations. And we played with all the stuff, and he never, ever said “don’t touch that,” and we always wanted to take out the lasers and clap erasers in front of them. It was play but it was special play, because it was stuff that was actually for grown-ups but we were allowed to play with it. It was a wonderful, special place. My father was very happy when he was there and we were happy to be with him. Being in a laboratory was always just the most wonderful, comforting, familiar, happy, safe place—and I still feel that way. Which is a little funny because it’s clean and bare and it’s not soft. It’s angular, but it just feels to me like the most wonderful, softest, warmest, safest place in the world.

Why are working relationships in science special?

Science isn’t for everyone. I mean the hours, the hours and hours that you spend sealed in a fairly barren room as time marches by and life goes on. It takes an unusual person to stay in that room and feel like I don’t want to leave. No matter what happens I love it here and I don’t want to leave. Once you have your own key you never have to leave, right, ever, and not everybody sees that. That’s not everybody’s dream version of how to spend your life. It’s just not and thank god, you know. The world needs to turn on so many other wheels. But I think when you find someone who feels the same way then that just enriches the experience to an extent that … it’s a special kind of sharing, and it creates a very special kind of bond. And that’s what I tried to express in the book, is that there is a bond between people that comes from this work and comes from the close quarters and the isolation and the contrast of working on ideas that are so noble, but using tasks that are so banal. You know, sitting and labeling and re-labeling things for hours on end, and there’s something … I don’t know, I mean I describe it as almost a religious experience but I don’t because I don’t have any other model for comparison. But I think it’s how monks must feel, you know, when they do this chanting or they take these vows of silence or whatever it is. I think not everyone can get that, and not everyone feels the same way but everybody knows what it’s like to have someone that gets them.

What advice would you give to parents of aspiring scientists?

This is something I always try to say, is that most scientists are drawn to their subject in a very inexplicable visceral way. And that’s, I think, the most important thing I tell people with daughters or sons or whatever, is that to identify that; that will come out very early. For example, birds, I know people that study birds. I know people that will travel halfway around the world and sit out in the rain for days on end hoping that a certain bird flies by. Now, I look out at birds and I say “that is a bird” and it leaves me utterly cold. I can respect that somebody wants to know that bird’s inner workings, and I can value the fact that somebody does know that bird’s inner workings, and I can listen politely to an overview of that bird’s inner workings, but I will never have that … for better or worse, that’s not my destiny.

Now leaves are something different. I feel drawn to leaves in a way that I cannot explain and I always have. I remember when I was in school and we were supposed to make a leaf collection. We were supposed to get 20 different leaves, and I remember my parents dropping everything and driving to Indiana to arboretums and botanical gardens, and I think my collection was 150 leaves in the end, which is great. It was great. It’s something I’ll remember all my life. And, you know, my parents and I don’t see eye to eye on everything—but I got from them the strong message that number one, your education is something worth going overboard for. Pull out all the stops. Number two, that my inexplicable passion for these things was good, and it was a good thing about me. And it was something that the people in my life should support and jump on board for and enjoy. Those messages have stayed with me very strongly. I think that’s important. So Nautilus shows you stress or age or space, from all those different angles, and I know some people feel that way about stars, you know, they can’t stop looking up at the stars or whatever it is. That’s the piece where people’s scientific potential lies. That’s what I’ve seen in students and that’s what I’ve seen in myself.

Do you think there’s a dispassionate, mechanical caricature of scientists that is served to the public?

Okay. So this is important. So that’s true and it exists for a reason. That image serves science and it propagates science and it protects science. Science is deeply invested in the idea that not everyone can do this. It goes contrary to all the lip service—increasing amounts of lip service—that we pay to the idea that we need more people in science and that we need to foster people’s abilities to do science, etc. Now, I’m not trying to talk people out of being scientists. And hopefully I’ve proved enough of my commitment to scientists that nobody would look at me and think that I couldn’t recommend this as a life that is a beautiful, beautiful thing. But I can say from the inside that most scientists haven’t thought very hard about whether they really want to live in a world where everyone can do science. And whether it’s not, this knowledge is not a valuable elite commodity.

Most scientists are drawn to their subject in a very inexplicable visceral way.

When I was deciding what to do with my life, I felt a need to write. I was very drawn to books in a powerful way. I wanted to study them, with a capital “S.” When I got to college I learned very quickly that if I became a writer society would let me die on the street. And if I became a scientist I would always have a roof over my head and a job, and my labor would be something that people needed. That difference has always struck me as so arbitrary, because I was willing to put my soul into all those activities but it became very clear to me that society viewed one of them as important and one of them as optional. So, let’s think about that for a minute. If you’re a scientist, if you have scientific skills, society believes on some fundamental level based on what I just said that you deserve to eat, you deserve to sleep in a dry place, you are entitled to all these things. Now, if we conceptualize science like we do art—something creative that anyone has the potential to do, maybe not everybody is great at it, but it’s this approachable thing that people write books, etc.—why should they be rewarded for that in the same way? What if we really did view science like that as this thing that anybody can do? How would we conceptualize the value of it? Would we lose that protection? Would we lose this protection that scientists have from the street? From hunger? From unemployment? From irrelevance? So it always strikes me as hypocritical that especially when we start talking about how “oh we need all these people to become scientists and we’ve got to get them interested,” as if people’s personal yearnings are at fault. As if people aren’t already yearning for meaning and discovery and things like that.

Do you feel that the scientific establishment is making a sincere effort to include women?

Well, I don’t know if establishments can be sincere. People can, but institutions are a different thing, and science is an institution. I think women are doing science; it’s just not science that is compensated very well. My mother knew how to stitch a different tension into the thread of each button on the shirt based on how many times it was used relative to the others. You might sneer at that as an unscientific activity, but I would give anything to have an employee in the lab who got that fine scale understanding of force and tension, and understood the mechanical workings of all the small pieces. So I think … I mean “can women do science?” That’s a ridiculous question. “Do women want to do science?” That’s a more interesting question.

I’m cynical about efforts to change women into something better. Every time we tell girls to be something else, we’re also telling them that whatever they are isn’t enough.

I think wherever you look in the world, you see a field or an endeavor that’s not got women in it. You can ask yourself why aren’t there women there? And the answer is always the same: It’s because women aren’t welcome. I mean, there are women working hard everywhere you know. You can say well science is too hard. Well, women know how to work. There are fundamental mechanisms that work to discourage women from positions of influence and access, and science has a protected elevated position in society. I always go back to my original decision in college, to be a writer or to be a scientist, as an illustration of that. It’s arbitrary. And I think it’s the dynamics between men and women in the market place and in the classroom and in society as a whole, that’s much bigger than science. Those fundamental truths of how we’ve constructed society bleed into every endeavor that we’ve organized, and science is merely one of many, many endeavors that carries that curse.

I could rattle on and on, specific examples of times that I’ve been told that I’m unwelcome or, from various implicit to very explicit examples—to this day it never stops. People do get fed up and they leave. And if you don’t fit the mold there’s all kinds of this stuff.  Any kind of minority person who doesn’t fit the mold is going to have their own brand of unwelcome. But the interesting thing is you can’t get away from it. Okay so you leave science, there’s no magical place where these biases don’t exist. I’d like to imagine that they’re better in certain spheres, but I also know that they’re probably a lot worse in other spheres. The frustrating thing to me is that we’re talking about it on such a superficial level. You know “do girls have the right dolls to play with when they’re little? Do we have the right people on TV as role models?” And nobody wants to seem to tackle the fact that maybe we’re already invested in a much larger system that counts on the fact that we need to usher some people into more lucrative labor than others.

I’m very cynical about efforts to get girls into science. I’m very cynical about efforts that are meant to change women into something better. And, it’s time for them to be the new thing that is good to be. That’s fine for women who feel drawn to science—I’m certainly one of them. But every time we tell girls to be something else, we’re also telling them that whatever they are isn’t enough. You know, in 1950, my mother was an honorable mention in the Westinghouse talent search. That is something that is rare. Two other honorable mentions from 1950: One went on to win a Nobel Prize, and the other went on to win the Fields medal in mathematics. They were both men. She was not from a prep school out east. She was from a rural school in rural Minnesota—from a public school in rural Minnesota—and she tried to go to college and she didn’t have the money. This was 1950, and so she had a family instead. And that is with me every day, I carry that.

Tell us about the language you used in your book, Lab Girl.

We can talk about every adverb I used, we can talk about every adjective I used, we can about every adverb I cut and the way I constructed every sentence: because it was done with scientific accuracy. There is an entire parallel language that has been constructed for use in science, in order to remove science from the realm of every day discourse. That goes back to protecting it as a uniquely marketable skill set. It does.

I wrote this book and I said, “I don’t want to write for scientists.” I have written close to 70 papers in 35 different journals. I have written and written and written for as many audiences as I can possibly find within the scientific world. I want to talk to somebody else. After 20 years, in the field of studying plants, I’ve been talking to the same people for 20 years and so I wanted to write this book in order to talk to somebody new.

Now so you’ve got a tree and a tree sits in the sun and it biochemically uses energy from the sun and carbon from the air to make a sugar. And then it turns that sugar into a leaf or it pumps the sugar down into the roots or it mixes it with nitrogen and makes protein. It has various activities. It has to choose. So, the tree has made sugar out of energy from sunlight and carbon from the air and now it has other tasks. It makes a leaf if it’s spring. It doesn’t make a leaf if it’s fall. It transports it to the roots if it’s fall; it doesn’t do that if it’s spring, etc. There are other things it can do based on if an insect is attacking it, it might use that sugar to make a defense compound or a medicinal compound to apply to the site of the wound, etc. I talk about that as being a choice. The tree makes a choice. I should talk about that as an allocation, the tree allocates to one task versus another. Now, the fact that allocation is a good word and choice is a bad word, doesn’t mean anything. It’s just a reaction against me breaking that rule, using a word that you identify with, that you use every day in your activities, in your nonscientific activities. The other thing I’d say about making that choice, choosing that word choose instead of allocate, is I have earned that. I’m not walking around rubbing the trees and feeling their vibrations for some kind of spiritual message to me. I’m in the laboratory for hours on end for years of my life, studying this and publishing it and discoursing with my peers. I have come to these statements through a process of sincere and industrious earning.

The most fulfilling thing that I hear about the book is that people tell me “I understood this stuff: I’m not a scientist but I understood it,” and they’re somehow surprised at that. Somehow along the way science stopped writing stuff that people could understand and we’ve somehow got the reader blaming themselves that they can’t understand it. I mean what a scam. So that gives me great joy, is that people will even say “I was told I’m not good at science” or “I never did any of this stuff, but gosh, I liked your book. I understood it and I feel like I know something about trees. I feel like I could do this stuff” and that is what gives me real joy. It’s a sneaky textbook. You know, if you really read it and you take all that stuff in you know as much about plants as I would hope to be able to teach you in one of my courses. That is the part that is really joyful to me as a writer.

Is there a struggle to understand what human narrative we should apply to nature?

How to conceptualize nature—that’s a huge, huge topic. I would love to write an essay on that, or a book on that. I’ve analyzed this to some extent. We have this discomfort between enlightenment and romantic views of nature. Is it something that we manipulate or is it something that’s bigger and more expansive than we are? So who’s on top? In the romantic version, nature is bigger than we are, it knows more, it’s been  here longer, it has ways of sustaining itself and healing itself that we cannot understand. In the enlightenment version, we’re able to control everything about nature, we can fix it, it’s our duty to make it yield, etc. And, of course, neither one of those scenarios is really right. You hear people flip back and forth between the two rhetorics when they discuss environmental phenomenon. You know the green technologies and the solutions is always very enlightenment rhetoric, whereas the conservation strategies, protection of nature is always very romantic rhetoric, and we kind of flip back and forth as the argument serves. But the bottom line is nature doesn’t care how we conceptualize it. This is a purely human endeavor, and nature also doesn’t really need us to conceptualize it. In some ways, there is a lot we don’t understand. I’m not saying it doesn’t matter how we think about nature. I think we always are tempted to succumb to the idea that we’re more important than we are when we talk about the environment. The real challenge is living with the dissonance, living inside the dissonance of those two visions and continuing to work every day and take the measurements and walk the fields and count what’s there and talk to each other about what we see. That’s the challenge.

Why do you love trees?

Well, it’s also a complicated relationship. It’s like anything that you love to excess—sometimes I hate them. Sometimes I just think I just want to cut down every tree in the world, just because I’ve got these five that I cannot explain and it almost seems like they’re being inscrutable just for the sake of ruining my life. I mean it’s like any great passion; there’s parts to it. We grow plants in very specialized conditions that require round the clock monitoring especially toward the end. It’s exhausting and on the day that we harvest these things and kill them and pull off their leaves and do the measurements, I have to admit that that feels pretty good sometimes. I just feel like you little thing, you controlled my life for three solid months, and now I control yours and how does it feel? I know that’s … okay, anyway. The truth isn’t always pretty right.

But yes, I have a deep affection for trees. I don’t think they love me back and I don’t think they know me, and all that kind of stuff, but I love oak trees because there’s pretty much a species of oak that can live almost anywhere. They just seem so indestructible, and they just have so many things figured out that we don’t, like how to live on the planet for 100 million years without substantially wrecking everything or wrecking themselves. I wonder if we’ll be able to go 5 million more. So in some ways I feel like I can transcend all the stuff that human beings worry about, each other and money and how men and women treat each other, and all that kind of stuff. I feel like I can transcend that by looking at a being that figured it out.

People are drawn to trees. They’re bigger than us in almost every way imaginable. I mean there are trees that were around when you were born, and those same trees are going to be around for a lot longer when you’re dead. And so I think it’s natural that people have always tried to make sense of trees, and they do it using the tools that they have. They do it using their religious tools. They do it using their sensory tools. They do it using a mystical framework and I do it using a scientific framework. I count the leaves, I rip the leaves up, I go back and measure things. I think we try to make sense of the world and trees are always going to be a really magnetic draw for some of us, not because they’re like us—because they’re so very different.

What are some of the most interesting places on Earth for a plant lover?

I love Ireland, because it is so green. Ireland is so thoroughly green that the things that are not green stand out. You drive around and it’s like “oh my gosh, there’s a white lamb on that field of green.” And the shades of green, the million different subtle shades of green are amazing. Something about working in Ireland and being in Ireland is so immersive in the plant world. And it rains, which is miserable. It’s miserable to be outside in the rain for hours on end, not moving around, kneeling, counting moss plants or something. You get cold and you get wet, and it’s that kind of drizzle and it soaks you through etc. And then you just realize that all these plants they never go inside, they love this stuff. It’s a nice place where I go and really think this is their world, it’s not mine. I get to measure a few things, but I don’t know—that’s the real definition of exploration, finding yourself in a different world.

People are drawn to trees. They’re bigger than us in almost every way imaginable.

Hawaii is interesting because it’s the tropics, which means that everything is blooming all the time, which means that there’s just an incredible amount of plant sex going on everywhere you go. And everybody’s trying to make the biggest, showiest flower, and spit out the most seeds, and stuff like that. And so I’m constantly in Hawaii just bombarded with all this fertility and like frantic desperate … it’s like Caligula for plant life or something. So each of these ecosystems are different in a way that I appreciate not because of a mystical side; it’s my scientific side that allows me to appreciate that. It’s my scientific work that allows me to feel that and recognize it. And I like that crossover.

What happens to the Earth’s plants if atmospheric carbon dioxide levels go off the charts?

CO2 is an interesting thing, in that it’s basically money to plants. It’s a primary resource. The interesting thing about plant communities is that we’ve been flooding their economy with money for decades, more and more. And, just like if you went to Times Square and $1,000 dropped from the sky into the pockets of everybody who’s standing there, every one of those people would make a different choice on how to spend the money. Some people would save it; some people would run out and buy clothes; some people would gamble it away within 5 minutes, etc. And in a similar vein, every plant out there makes a different choice. Some build a bunch of new leaves; some make a bunch more flowers; some shunt it into their roots; some stop making defense compounds. I call that the Costco effect. If you go buy 100 rolls of toilet paper you’re going to use toilet paper at your house very differently than if you’re buying it roll by roll. So plants, if it’s that easy to make a new leaf, you’re going to treat the ones you have very differently, if that sugar is just coming in free.

We see all that, and now we’ve got you know 20 years of good research on how this effects plants, and it does affect them differently. But when we talk about back to us, back to humans, plants, first and foremost in a lot of our minds, are three things:  food, medicine, and wood. You probably stopped seeing it, but if you look around the number of articles around you that are made of wood is still incredible so it’s our biggest building material on the planet. Of course food all starts with grain and a lot of our important medicines are extracted from plants. So if we flood those three economies—those three plant economies—with money, we need to start thinking about what those plants will do and hence what will happen to those resources. Will wood be just as strong? Will it weather just as long? Will crops get bigger, smaller? Will they get less able to defend themselves against pathogens? That’s important. Will they be less storable, etc.? Medicinal plants—will those compounds be less potent? Will they be more potent etc.? There’s reason to believe at those very high levels, you know really busting out of what we’re looking at today, could affect plants very differently than the relatively small raises that we’re looking at in the last 20 years.

It’s a different world when money is free. And thinking about a world where plants operate utterly unconstrained by that particular resource is very interesting. One thing that happens of course is that other things come into play. I mean if I quadruple your salary but I don’t give you any more vacation time, you can’t take that around-the-world tour even if it seems cheap to you, because you can’t get the time off. So now it’s not money that’s limiting; it’s time. Plants have a similar thing in that nitrogen can become limiting, water can become limiting when temperatures go up. There may be less water available in very critical places. So the economy of plants can also tip based on these secondary limitations. That’s also very interesting to us. But I think we need to start wrapping our heads scientifically around some of these scenarios that nobody wants. You know nobody wants a hurricane on the Hawaiian Islands, but we have a system in place in case one happens. I think global change is going to be the same way.

What research are you doing that you’re most excited about now?

Right now, I’m interested in stress. We’ve done a lot of experiments around stressing plants to see how they recover and how they manage stress and things like that, which is funny because they’re actually pretty sadistic experiments. I mean, you can torture a plant until it’s this close to dead and then bring it back. You can do all kinds of things you could never get permission to do to animals, and it would be horrible to even think about doing such things to people—but plants are very much fair game in terms of any experiment you want to propose. Especially little small plants and stuff; which gives a kind of scientific freedom in terms of studying life. The interesting thing that we’re coming to is, what is stress? How do you define stress? One thing we’ve noticed is there’s a disconnect between what I think will stress the plant and how it actually reacts. So how do you measure stress? The same life event happens to two people—two people of the same species—they’re not going to react the same. So I can say well, I won’t give these little guys water for a few days, and then I’ll measure how much they didn’t grow, and then I’ll compare the stress between them. But I’ve already projected my own assumption about what stress should be into that experiment—lack of growth. I’m having a lot of fun thinking really deeply about how subjective the experience of stress is. Subjective in terms of human subject is one thing, but subjective in terms of individual experimental plants—that’s a whole other mind box that has to open in order to go there. So that’s what I can say about what I’m really excited about now.

What would you be if you weren’t a scientist?

I wanted to be a surgeon very, very badly. I didn’t have the money to go to medical school. Medical school is expensive, and graduate school in science—it’s free, and that’s the most important thing to tell people to make them be scientists. Law school is expensive, medical school is expensive, business school is expensive, graduate school in science is free with a capital “F.” So that’s why I didn’t go to medical school. I wanted to cut people up. I have very steady hands, I have a good memory, and I can be decisive in important situations. And I thought that I could do good work as a surgeon. But it wasn’t meant to be. You only get one life, you don’t get two lives, and maybe some med school will see this and accept me as an old lady and I’ll start my career over again. But that is something that I always will wish if I had another life, maybe I could really heal people and their wounds in a way that I’m not going to be able to with plants.
