❄️ Bolt + Ginkgo: forging the next chapter in ice-control engineering
I’m deeply excited to share that Bolt is partnering with Ginkgo Bioworks, Inc. in Ginkgo’s Defense Advanced Research Projects Agency (DARPA) ICE (Ice Control for cold Environments) program. The foundation of this work is one of nature’s most elegant and under-appreciated molecular toolkits: ice-binding proteins.
🧬 Nature’s ice engineers: where biology already wins
Across the tree of life — in fish, insects, plants, fungi, and bacteria — many organisms make ice-binding proteins (often called antifreeze proteins or IBPs/AFPs) that can:
- bind to ice crystals
- inhibit further ice growth
- prevent recrystallization
- modify ice morphology or adhesion
These proteins are nature’s way of managing ice rather than brute-forcing its removal. For example: Polar fish secrete antifreeze glycoproteins that depress freezing and prevent internal ice formation in subzero seas. Some insects, plants, and bacteria similarly use IBPs to survive freezing or frost stress.
🏷 Where IBPs already show up commercially (yes, in your ice cream shelf)
These aren’t just biological curiosities: IBPs have real commercial footprints already:
- Ice cream & frozen desserts: Unilever has used genetically engineered yeast to produce “ice structuring proteins” (essentially AFPs) to control ice crystal growth in ice cream, thereby improving creamy texture and reducing the need for other additives.
- Cryopreservation & biobanking: Because IBPs can help reduce ice damage during freeze–thaw cycles, researchers explore them as adjuncts in cell, tissue, sperm, embryo preservation media.
- Frozen food shelf life & frost protection: Some studies highlight IBPs or synthetic mimics as candidates to slow ice recrystallization in frozen foods, maintain texture, reduce freezer burn damage, or protect seeds and biological materials in cold storage.
So we already carry bits of this biology in our everyday lives and now we (Bolt + Ginkgo) aim to push far beyond, into high-stress formulations and extreme environments.
🔬 From nature to formulation: how Bolt + Ginkgo are stepping up
- Ginkgo is engineering, screening, and optimizing a library of novel ice modulating proteins, building on the lessons of nature but tuning for performance beyond what evolution gave.
- Bolt is taking those proteins, formulating them, stress-testing them, and pushing toward real applications under real conditions.
We aren’t just copying what fish or insects do, we’re accelerating the feedback loop: design → test → optimize → deploy.
In the months ahead, I’ll share milestones, surprises, promising leads, and (if we’re lucky) breakthroughs. Immense gratitude to the teams at Bolt, Ginkgo, and DARPA for believing in this biological frontier.
