This is the script and slides from a talk I gave in Malmö Sweden at “The Conference” in August 2022.
When I say I’m a synthetic biologist, I usually get one of these three responses:
The first and probably my favorite is 😳what are you even talking about? This one is great, someone who’s never heard of synthetic biology! A blank slate!
For the techy types, I can explain that it’s like programming DNA to develop new kinds of products,
or for the more arty types maybe I can explain that it’s about designing biological materials,
or for the more normy types with real jobs I can just say “I work in biotech.” I work for a company called Ginkgo Bioworks that does genetic engineering as a service for other businesses.
The second type of response is the jokes, and I also love these. “Oh synthetic biology, it’s like real biology but made up!” Yes, kind of! Exactly! We ARE trying to make things with biology.
Or maybe something more like “huh, a synthetic biologist—like you’re a robot doing experiments?” Um also sort of? In my lab days I sometimes felt like a robot
and these days at Ginkgo we use tons of robots to make biology easier to engineer.
There’s a third one that looks at synthetic biology as a brand, which is something I think about a lot in my role, where I work on design, communication, ethics, policy, perception–in one word, our brand.
Brand comments actually takes two forms: On one side you have the people who think that synthetic biology is only a “good brand”—is synthetic biology anything at all other than a rebranding of genetic engineering that’s better at raising capital from VCs, or perhaps tricking people into not thinking about GMOs? On the other side you have the people who think synthetic biology is a terrible brand “don’t you know people hate things that are ‘synthetic’? You really should rebrand.”
So I’ll start with the latter—the people who think I should rebrand since synthetic is bad—because I get it, synthetic has come to mean anything made with old biology, from the fossil fuels that humans have managed to extract from the ground and refine into the myriad things that we enjoy in our everyday life. Synthetic means unnatural, it means pollution, chemicals–it comes from this world, not the world of living things. No one wants synthetic, everyone and everything wants to be natural (no matter how they are actually made).
So I’d like to offer a defense of synthetic, not because I love smoke stacks and fossil fuels and not because it’s a “good brand” for GMOs, but for ideological reasons—because at its heart synthetic is about bringing things together to make something greater than the sum of its parts.
Synthetic does not need to mean the opposite of natural, and in fact the reason why we think it does is exactly why I think we need to embrace synthesis again. The concept of nature is built on a fundamental division.
It is about cleaving ourselves as humans from everything else. We define nature as that which is not us, nature is everything outside of the human world. Nature is the opposite of culture, it’s the opposite of technology.
In this formulation, nature is separate from and it is below us, something that we must dominate and control so that we may survive and flourish. Synthetic materials made by humans therefore offered us better living through chemistry because technology was meant to save us from the vicissitudes of the growing cycles and the whims of weather and pestilence.
Today, many of us in industrialized parts of the world have become free from the tyranny of nature, but we suffer from new tyrannies of pollution and climate change. We therefore seek out ways to go back to natural, but even now “natural” still depends on the same fundamental principle of separation and control, which then permeates the marketing and culture of natural products. “Natural” now is about the quest we must go on to choose the right products to purify ourselves from the sins of synthetic chemistry. Natural in this case isn’t really about connecting with that which is outside of us, but again becomes about a kind of exclusion, this time what our products are ”free from.” These new purity rituals define so much of our relationship to our everyday life and culture, from the foods we eat to the cosmetics and even medicines we choose.
Much more sinister and damaging is how nature and science have been used as tools of social control, to justify the divisions and dominations of colonialism, white supremacy, and patriarchy. From ideas about women’s “natural” roles in society, to the “natural” or biological obviousness of the gender binary and heterosexual monogamy, to “natural” differences between populations from different parts of the world, this kind of appeal to “scientific facts” about the “natural” order of things has always been used as a tool of oppression.
The division between nature and technology also means that we have inherited a very atrophied imagination of what technology can be, and a technology that continues to replicate these social structures of domination. “Technology” becomes a very specific type of work, associated with a very particular type of person. It affects what we value, what we invest in, what we pay attention to. Ursula Le Guin lamented this in a rant on technology and about how her own work was devalued as less “scientific” than other kinds of sci-fi because it deals with technology in a much more expansive sense, as, in her words, “the active human interface with the material world.”
Instead of this expansive technology, we have a much more limited view of technology and technological visions that seek to entirely escape the physical reality of this world while still enforcing scarcity in order to perpetuate systems of control.
I think it’s time for a very different vision. Not to rebrand synthetic biology, but to reconfigure the relationship between nature and technology and the synthesis of the two. We don’t want the divisive technology of the metaverse, but the synthetic technology of the meatverse.
We need to celebrate the meatverse because our technology is also pathetically small when compared to what biology can do. What is a computer compared to four billion years of evolution? Of organisms that can grow anywhere, of seeds that can grow into plants, a pulling carbon dioxide out of the atmosphere. Humans can’t figure out how to make things without asphyxiating our planet and filling it with garbage. Biology makes all of us, all our bodies, all of this in a fundamentally regenerative way. We have to learn to work with biology, and bring these worlds together synthetically.
This is an urgent task. We have reached the end of what is possible to sustain with technology cleaved off from nature. Our attempts to dominate nature in order to free ourselves from the scarcity of our environments have led to a world where we have more than we need but we face a threat of extinction because of our technology’s exhaust. Murray Bookchin, a theorist and pioneer of the environmental movement wrote in his book Post-Scarcity Anarchism that “Man had to acquire the conditions of survival in order to live, now we have to acquire the conditions of life in order to survive.”
I believe that for us to survive and flourish, the future must be synthetic: a union of nature and technology, and of science and technology with politics, art, and culture. These synthetic movements must remove not only our desire to dominate nature but also to dominate each other.
So I’ll leave you with a sketch of what this synthesis could look like. A world where we can revel in our biological experience and our creative energy can grow and shape the physical world. Where we can design new materials and new experiences together with nature. Where students and scientists can exchange new biological programs the way they share make-up tips on tiktok.
Where your local pharmacy brews new strains of microbes producing the ingredients and medicines you need, grown to order in custom strains. Your local flower shop sells seeds with custom genomes, accounting for our allergies and preferences.
Where your living room is appointed with the coziest mushroom material, and our fashion is shaped by the dynamics of cell cultures and the custom colors and patterns we co-design with them.
Where, biological programmers log into the wood wide web using the latest web-tree protocols. Our conversations are written in DNA. Where industrial pollution once left behind damaged soil, we grow new forests.
I believe that the future is synthetic—because the future depends on what we can imagine and make together.
I hope you’ll join me.
In the meatverse, creative energy shapes our physical world. We design, together with nature, biological processes to grow what our fleshy bodies need. The materials that make our buildings and soften our spaces; the fabrics and dyes that delight our senses; the foods that fill our stomachs and fuel our cells.
In the meatverse, biological programmers log into the wood wide web using the latest web-tree protocols. Our conversations are written in DNA. Where industrial pollution once left behind damaged soil, we grow new forests.
In the meatverse, there’s a new kind of tiktok house. Kids whose grandparents played with the first home cloning kits live together, dazzling each other with newer and stranger organisms. We shop on Etsy for the plasmids that genetically engineer our shared gardens. With custom genomes, the fruits and vegetables account for our allergies and tastes. Our house plants glow. Maybe our pets do too.
The children of the meatverse grow furniture and clothes alongside our food experiments, allowing them to gently decay when it’s time for a new look. When it’s our turn to make dinner, we program a cell printer to stack animal cells (grown in the neighborhood bioreactor) into different shapes and forms. The latest gimmick in celebrity meats gets eye rolls from around the table, but the flavor is unimaginable. Different programs for that same neighborhood bioreactor produce common medicines from antibiotics to insulin — everything we need.
In the meatverse, life is good.
In the two weeks since the election, I’ve seen a lot of talk about “standing up” for science. Science Magazine put an ad for new AAAS memberships under a photograph of the white house, with a call to “stand strong” and “speak up for science” emphasizing funding and research investment, science communication, and climate change.
In the same two weeks, I also saw:
When the EPA transition is being led by someone who said “I am not a great believer in man-made climate change,” it is vital that we all stand up for the future of our world. But when overt racism is now daily coming from the most powerful people in the country and hate crimes are rampant, we must also stand up and recognize when science further reinforces oppression and speak up for marginalized people.
The examples above show how “objective” scientific treatment of social phenomena can backfire and enable racist policies. An algorithm to detect “criminality” from facial features is going to be biased the same way our criminal justice system is biased along racial and socioeconomic lines. A program to match students to courswork based on genetics will be biased the same way our educational system is along racial and socioeconomic lines. Speculation about “superhumans” traffics in racist stereotypes about Chinese ethics and the problematic belief that ability is defined more by our genes than by our environments.
Scientists aren’t immune to the blind spots and biases of our culture and science has long been an instrument of normalizing and naturalizing prejudice. Today, those scientists are more likely to complain about “political correctness” than appeal to our sense of “natural” hierarchies. At the same time, white supremacists tout James Watson’s Nobel Prize alongside his abhorrent beliefs about intelligence and race (let’s save discussion of the “anti-science” label for another time).
To stand up for science in our uncertain political time, we have to think beyond budgets—I’m going to stand up for a better science. I’m going to stand up for scientists who are being harrassed, whose identities leave them vulnerable, and stand with all who are standing up for a science that includes diverse voices. I’m going to stand for science that works for all of us.
I love this passage from Isaac Asimov’s I, Robot predicting the fungal economy:
More on yeast making stuff in 2015 from WIRED:In the first place, by far the largest crop we deal with (and the percentage is growing) is yeast. We have upward of two thousand strains of yeast in production and new strains are added monthly. The basic food-chemicals of the various yeasts are nitrates and phosphates among the inorganics together with proper amounts of the trace metals needed, down to the fractional parts per million of boron and molybdenum which are required. The organic matter is mostly sugar mixtures derived from the hydrolysis of cellulose, but, in addition, there are various food factors which must be added.
“For a successful hydroponics industry - one which can feed seventeen hundred million people - we must engage in an immense reforestation program throughout the East; we must have huge wood-conversion plants to deal with our southern jungles; we must have power, and steel, and chemical synthetics above all.”
“Why the last, sir?”
“Because, Mr. Byerley, these strains of yeast have each their peculiar properties. We have developed, as I said, two thousand strains. The beef steak you thought you ate today was yeast. The frozen fruit confection you had for dessert was iced yeast. We have filtered yeast juice with the taste, appearance, and all the food value of milk.
"It is flavor, more than anything else, you see, that makes yeast feeding popular and for the sake of flavor we have developed artificial, domesticated strains that can no longer support themselves on a basic diet of salts and sugar. One needs biotin; another needs pteroylglutamic acid; still others need seventeen different amino acids supplied them as well as all the Vitamins B, but one (and yet it is popular and we cannot, with economic sense, abandon it)-”
In the early 1970’s, several Dutch universities created “science shops” (wetenschapswinkels) with the aim of democratizing science. The science shops connected public interest groups who had scientific questions with university students and researchers who could provide answers. Opening access to university research would help activist groups achieve their goals, and would also have an impact on the universities themselves. In an essay for the journal Science, Technology & Human Values, Joseph Wachelder writes about the more radical goals of the science shops early on:
The democratization of science in fact implied a general and even radical transformation of society. The aim was to reorient science toward the social needs of workers and disadvantaged groups and to fight the vested interest of the establishment and the so-called military-industrial complex. In those early days, the political Left pushed science shops as one means of transforming both science and society in radical ways. Unions, targeting issues such as occupational health, social security, and working conditions; environmentalists; patients’ groups; third-world activists; and, slightly later, women’s liberation groups considered themselves as partners in pursuit of a new and better society.
I read about the science shops for the first time over the holidays in Making Genes, Making Waves, Jon Beckwith’s autobiography about his research in molecular biology and his political activism. Given the current fad for “democratizing science” I was surprised that I’d never heard them mentioned before.
Indeed, today’s democratization looks a lot different from the democratization pushed by science shops and radical science movements of the 70s. Science for the People, an activist group of scientists and engineers founded in the early 1970s, organized against the misuse of science by military and corporate interests and advocated that science work for marginalized people rather than maintaining the status quo. A powerful symbol for the group was a fist raised in solidarity next to a hand holding a flask. Alice Bell notes in a recent article on activist science that, “The fist of solidarity stood in front of the chemist’s flask here, not simply used to hold science up high.”
Compare that with Science for the People, a Canadian radio program about science, which rebranded in 2013 from “Skeptically Speaking.” Their logo echoes the Science for the People cover image from 1970, but here the fist holds up a test tube—literally holding science up high. In a blog post about their rebrand, the producers discuss what “science for the people” means to them:
We’re about getting the word of something we love to people who might not hear about it anywhere else, in the hopes that maybe, just maybe, they’ll love it a little too. We’re about taking tough scientific concepts and teasing out what matters. We’re about taking the latest in scientific progress and relate it to people like our friends and our families, and our communities, and our society.
Telling people about your love for science is great, but as Bell notes (referring to the flask-toting fist on the cover of the Geek Manifesto), “Looking back at these earlier radicals, [it] seems to pale to a Che Guevara T-shirt in comparison.”
Other efforts seem similarly pale when you begin to examine their claims about democratization in light of what democratization meant to more political generations of scientists. Like the Science for the People radio program, many of these efforts are focused on the one-way transmission of science from the academy to the public, rather than a radical transformation of science itself to address public interests.
Open access publishing has made it easier to publish and read scientific articles, and is gradually (hopefully) chipping away at the tyranny of the impact factor in academic career advancement. These are worthy goals which I support whole-heartedly—I’ve published most of my papers in open access journals—but making papers open to download doesn’t necessarily make science democratic and open to everyone.
Likewise, recent efforts to get more people involved in scientific research have been branded “citizen science,” but unlike the science shops where the citizens dictated research directions, citizen science projects simply allow non-scientists to volunteer their time collecting or analyzing data for professional researchers. These projects can be great learning experiences, allowing non-scientists to get a better picture of the scientific process, as well as great research experiences, allowing scientists to explore topics that they couldn’t have done without the expanded team. But letting people do free work for you isn’t the same as doing work for people.
In synthetic biology, “democratization” has recently been used as a marketing ploy for companies that are selling DNA or DNA editing software. Cambrian Genomics and Genome Compiler both claim to “democratize creation,” an empty statement that helps drive press coverage and TED invitations in the crowded genetic engineering market. Both companies are selling slightly different, cheaper, or easier to use versions of things that have been sold to molecular biologists for decades, but claiming that their versions will suddenly make it possible for “anyone” to do genetic engineering. Making cheaper and more accessible laboratory tools is great, but it’s worth asking what else is necessary to truly make “creation” accessible (I’m not going to get into the differences between synthesizing DNA and “creating life” here, but suffice it to say that I don’t agree with that part of their phrasing either). There are many other tools, training, and above all a reason to do it that are all necessary in order to make a “creature.” It’s no surprise then that, according to SF Gate, Cambrian currently sells DNA primarily to biotech giants like Roche, GlaxoSmithKline, and Thermo Fisher. If you don’t work to really democratize science, you’re just making cheaper tools for the people who already had access to them. (Also hype, lots of hype.)
The contemporary projects that seems most like the 70s Dutch science shops are today’s hackerspaces and community labs, where non-expert scientists can explore techno-scientific questions on their own time (and usually on their own dime). While there are a huge variety of projects and educational goals in these spaces, a particular kind of “hacker” has gone mainstream (and even received DARPA funding). Tinkering in a garage is now seen as the first step towards starting the next multibillion dollar Silicon Valley company. Hackerspaces can be the site of anti-establishment thinking, but they are also becoming part of the military-industrial complex.
None of these projects are necessarily bad. By and large, they all point towards a broader positive shift happening in the scientific community towards more transparency, accountability, diversity, and public involvement. But we shouldn’t let something as important as democratization become an empty label. We need to be critical of self-proclaimed democratizers—who is benefitting and who remains left out? Who is calling the shots and who is working for whom? Where does the money come from? How can we do science better?
It’s been almost five years since I updated this version of Oscillator. In that time a lot has happened in my life, in synthetic biology, and in science blogging. I moved my blog to Science Blogs and then to Scientific American. I published academic articles about bioenergy, symbiosis, olfaction, and design. I finished my PhD and a couple postdocs. I taught engineers and artists about biology. I wrote about a lot of things besides synthetic biology, and I started a new magazine.
Returning to this blog is both refreshing and embarrassing. Reading my old posts — or worse, my old drafts — reminds me of what excited me about synthetic biology and shows me how much I’ve learned since then. I haven’t been able to write nearly as often as I did five years ago, but my plan is to sporadically update this blog with links and short posts about the things that are exciting me now.
I like using synthetic to mean “working together”, in “real” synthetic biology as bringing together (synthesizing) a lot of components from different living things in order to create a unique whole, and in “natural” biology in terms of how every living thing must live together with others in communities made up of complex interdependent relationships. I’ve recently been reading a lot of Lynn Margulis’s work on Serial Endosymbiotic Theory (SET): how eukaryotic cells developed through multiple endosymbiotic events between different species of bacteria, with early cooperative relationships leading to intricate co-dependence and entire new domains of life. I love this picture from her article “Serial endosymbiotic theory and composite individuality” for its complexity and for highlighting how deeply connected all life on earth is. We are all synthetic communities.
Rubber can be made chemically from fossil fuels, but natural rubber from tropical trees is still the best source, and in many cases the only usable one (car tires need a lot of natural rubber for the right combination of strength and elasticity). Besides being difficult to grow and relatively inefficient, rubber trees are also facing a fungal plague that could potentially wipe out natural rubber within the next few years. Many labs (including mine) are trying to find or engineer different sources of biological polymers. According to a neat article in The Economist, two groups are working with dandelions as potential a new source of natural rubber. One group is using RNA interference to knock down the expression of a gene that makes the rubber polymers that the plant already makes difficult to process, and the other is using more traditional breeding technologies to improve rubber production, selecting and crossing high producers. Not only do dandelions already produce significant amounts already, but their fast growth and ability to grow just about anywhere (which makes them such good weeds) may make them a valuable agricultural commodity.
It’s an interesting project in many ways. Biological polymers are a fascinating and very broad subject, and understanding and engineering how enzymes make and break down these polymers will undoubtably be important for industrial biological engineering. Moreover, a sustainable biological method for producing rubber locally (instead of the current synthetic methods) will be important for environmental conservation and decreasing oil dependence.
However, this also means that there will be serious competition for rubber tree farmers, with likely many negative effects for the economies of Malaysia, Thailand, and Indonesia, the world’s top rubber producers. This has already happened, when the first round of synthetic—but not as good—rubber entered the market, as well as when indigo dyes began to be chemically synthesized, irreparably damaging the Indian dye economy. These and other issues are discussed in an interesting article by Political Scientists working at MIT, “Aspects of the political economy of development and synthetic biology” from a special issue of Systems and Synthetic Biology. These are important but often neglected aspects of the discussion of the risks and benefits of the potential applications of synthetic biology.
