Material Ecology: designing with nature instead of against it
Neri Oxman frames nature as everything outside “anthropomass” and argues that human-made products have increasingly separated humanity from the natural world. She introduces her guiding aim: re-integrating engineering and computation with nature to “grow” rather than “build.”
- •Nature defined as non-anthropomass; humans historically designed separation from nature
- •Goal: return to deep connection while bringing tools of computation and engineering
- •Nature’s “wisdom” as something beyond human notions of intelligence
- •Design as both creative practice and scientific discovery of new truths
- •Vision: making the built world behave like the biosphere
- 3:27 – 7:08
Biomass vs anthropomass: the crossover moment and what it implies
Oxman discusses Ron Milo’s concept of anthropomass and the 2020 crossover when human-made mass outweighed all living biomass. This becomes a catalyst for rethinking the technosphere as something that could be designed to function like the biosphere.
- •Anthropomass exceeds biomass as a turning-point for civilization
- •Technosphere vs biosphere imbalance (plastics, concrete, asphalt, cities)
- •Thought experiment: what if we could grow an iPhone, a car, or a building?
- •A ‘Turing test’ for grown vs made—could products be indistinguishable from nature-grown?
- •Reframing progress: cities and products that heal and augment nature
- 7:08 – 11:26
Large molecule models: giving nature bandwidth and an interface to computation
The conversation shifts to augmenting nature with computational tools—an “iPhone for nature.” Oxman proposes learning the cross-kingdom ‘language’ of life and building models that let organisms access information and make decisions without top-down human control.
- •Idea: ‘Neuralink for nature’—interfaces that expand nature’s bandwidth
- •From LLMs to “large molecule models” that capture biochemical communication
- •Mission: quantify/qualify the language across kingdoms of life
- •Hypothesis: nature seeks increased information with reduced entropy
- •Ethics and responsibility as prerequisites for augmentation
- 11:26 – 16:32
Oxman (the company): three scales of deployment and a CO2-to-soil product loop
Oxman outlines the company’s multidisciplinary team and a roadmap spanning molecular interfaces, grown products, and novel lab infrastructure. She describes an end-to-end biodegradable product concept that begins with carbon inputs and returns to soil to support new growth.
- •Team composition: designers, roboticists, microbiologists, chemists—‘Noah’s ark’ of disciplines
- •Three scales: molecular language/interface, product growth, and controlled environments
- •Product vision: start from CO2/methane/wastewater → wearable/product → soil → edible plant
- •End-to-end design to avoid hidden non-biodegradable steps (glues, coatings, assembly)
- •Ambition: factories of robots + microbes producing closed-loop materials
- 16:32 – 18:32
Computational templating: how robots and environments collaborate with organisms
Reflecting on the MIT Mediated Matter years, Oxman explains “computational templating” as a method for guiding biological fabrication. She illustrates how physical and environmental templates enable a duet between technology and living organisms to produce complex structures.
- •Mediated Matter’s focus: fibers, cellular solids, biopolymers, pigments
- •Computational templating as the common philosophy across projects
- •Multiple template types: geometric, material, environmental, chemical
- •Silk Pavilion: water-soluble meshes + robot-controlled heat/light to guide silkworm behavior
- •Shift from one-off museum pieces toward scalable, principled platforms
- 18:32 – 31:20
Hero organisms and swarm-like emergence: silkworms, termites, bees
Oxman critiques the industry tendency to “bet on” a single hero organism and instead treats organisms like movements in a symphony. She explores tradeoffs between material sophistication and communication, and how technology can induce unexpected collective behavior.
- •“Hero organism” as the biotech equivalent of a ‘42’ answer—and why that’s limiting
- •Two-axis lens: material sophistication vs communication (termites vs silkworms)
- •Silkworm insight: flat patches emerge without vertical anchors; used to assemble a dome
- •Emergence: when outcomes aren’t fully predictable and organisms exhibit new coordination
- •Provocation: moving from templating to agency—organisms ‘owning’ the code
- 31:20 – 38:20
Synthetic apiary and space bees: designing environments before designing with life
Oxman describes building a controlled ‘perpetual spring’ environment for bees to reduce winter die-off and explore symbiosis in cities. The team then miniaturizes this into a life-support ‘product’ that sends bees to space and back—alive and reproductive—while enabling new scientific findings.
- •Principle: before templating, design-for—create mutualistic conditions
- •Synthetic apiary: temperature/humidity/light control; bees thrive and produce honey in winter
- •Space experiment on Blue Origin New Shepard; aim to outperform 1982 NASA outcomes
- •Pheromones (e.g., Nasanov) used as part of the life-support strategy
- •Nature paper: gold/silver nanoparticles reveal bees recycle wax
- 38:20 – 47:46
Engineering with bacteria: Vespers, hybrid living materials, and ethical boundaries
The discussion moves to microbial fabrication via E. coli in the Vespers “death masks,” which embed chemical signals and living pigment-producing bacteria. Oxman connects the work to platform technologies (pigments, antibiotics, melanin) and clarifies her ethical stance on genetic modification across organism types.
- •Vespers as ‘living products’: masks based on legacy/biology, not facial geometry
- •Technique: printer-embedded chemical signals + bacteria patterning at ~20-micron voxel scale
- •Hybrid Living Materials (HLMs) emerge as a new materials class
- •Platform implications: pigments → antibiotics → melanin and more
- •Ethics: refusal of transgenic silkworm proposals; different ethical calculus for bacteria
- 47:46 – 56:14
Growth capsules and directed evolution: wet labs with programmable ecologies
Oxman describes a new lab concept: high-control growth capsules that combine wet-lab genetics with fine-grained environmental templating. The goal is to create a ‘breadboard for biology’ enabling high-throughput experiments for materials, food, and products—while probing emergence beyond templates.
- •High-throughput directed evolution paired with top-down environmental control
- •Capsules as ‘ecology in a box’ with programmable oxygen/CO2/nutrients/light/humidity/temperature
- •Applications: transparent wood, shoes, construction materials, future foods
- •Time-travel concept: emulate past/future climates to study taste, behavior, and resilience
- •Emergence post-templating: systems gaining their own rules (agential material)
- 56:14 – 1:08:54
Plant communication and functional fragrances: decoding molecular languages
Oxman argues that plants already ‘speak’ through volatile chemicals and stress signals, and that decoding those molecular messages could transform agriculture and design. She proposes functionalized fragrances as a first interface layer—tools that ‘inspire’ plant behavior while respecting agency and system-level impacts.
- •Fresh-cut grass smell as distress signaling (green leaf volatiles)
- •Plant intelligence and ‘slow’ timescales; importance of circadian molecular rhythms
- •Precision agriculture: move from late visual detection to early molecular diagnostics
- •Functionalized fragrance as a nature-interface product (message in a bottle)
- •System thinking: ecological sourcing and full energy/material budgets beyond the object
- 1:08:54 – 1:47:14
Einstein’s letter, beauty as agency, and the power of imperfection
The conversation broadens into philosophy: love as a universal force (via Einstein’s letter) and beauty as a manifestation of agency. Oxman and Fridman explore emergence vs empowerment, creativity as letting go, and why imperfection—flaws and vulnerability—enables connection and meaning.
- •Einstein’s letter: love as a force that ‘governs all others’
- •Beauty defined as agency; Buckminster Fuller: if it isn’t beautiful, the solution is wrong
- •Empowerment vs emergence: directionality vs multidirectionality; soft control
- •Imperfection (wabi-sabi): signals movement, prevents sterility, enables growth
- •Flaws as vulnerability and increased ‘surface area’ for connection in relationships
- 1:47:14 – 2:01:55
Extinction, AGI, and alien life: shifting timescales of life and intelligence
Oxman reflects on mass extinctions, death as part of life, and how definitions of life depend on timescale and observer. She engages the fear/hope of AGI, imagining scenarios where human agency fades but nature’s agency could rise—then turns to the possibility of alien life both beyond Earth and all around us on it.
- •Life/death cycle through extinctions; the sixth extinction as a present reality
- •Definitions of life depend on organism and temporal scale (bacteria vs redwoods vs AGI)
- •AGI: hopeful and terrified; novelty vs self-awareness; risks to human agency
- •Provocation: upload human knowledge to nature to expand nature’s decision-making
- •Alien life: uncertainty about elsewhere; strong belief in ‘aliens’ around us in Earth’s biosphere
- 2:01:55 – 2:18:25
Music, movies, and advice: wonder, discomfort, love, and calling
In the closing stretch, Oxman speaks about music as a universal language and film as a model for project-making and narrative. She shares favorite films and culminates with advice for young people: cultivate attention and gratitude, embrace discomfort for growth, and pursue a calling rather than an externally imposed career.
- •Music’s unique emotional access; waves as universal language (Beethoven, Bernstein, Kissin)
- •Favorite films: The Godfather, 2001; working with Coppola on Megalopolis
- •Creative process: combine timeless texts with timely technologies; ‘begin again’ mindset
- •Career guidance: seek discomfort, surround yourself with people smarter than you
- •Life guidance: presence, gratitude, love; focus on calling over career
