Barcelona Is Building a Frozen Ark for Endangered Species — And AI Is Driving It
In Barcelona, scientists are building a biological deep freeze for endangered species — storing genetic material from nearly 300 species and using AI to unlock the future of conservation. Jeremiah Pouncy explains how the Barcelona CryoZoo could change everything we know about saving wildlife from extinction.
The International Union for Conservation of Nature currently lists more than 47,000 species as threatened with extinction. That number is staggering — and it is growing. For most of those species, there is no safety net. No backup. No second chance once they are gone.
Barcelona is trying to change that.
The Barcelona CryoZoo is one of the most ambitious conservation science projects on Earth. Born out of the Barcelona Zoo Foundation in partnership with leading research institutions, its mission is to collect, preserve, and study biological material from endangered species before it is too late. Think of it as a genetic library — but instead of books, the collection is made of living cells, frozen at temperatures that stop time.
The numbers are already impressive. The CryoZoo has stored over 2,000 samples from nearly 300 species, including reptiles, mammals, amphibians, and fish. But the team is not just freezing cells and calling it conservation. They are mapping genomes, profiling active genes, and studying chromosomes to build a scientific archive that is open to researchers around the world. The goal is not just preservation — it is understanding.
A new competitive grant from wildlife conservation organization Revive and Restore is now funding the next phase of that work. Scientists will use artificial intelligence and machine learning to identify exactly which genes are required to reprogram ordinary animal cells into stem cells. This matters enormously because stem cells are the biological raw material for regeneration, reproduction, and ultimately, the survival of a species. If researchers can figure out the reprogramming code for one species, that knowledge can be adapted for others — potentially without ever needing to collect new samples from wild animals.
Over the next two years, the CryoZoo team aims to crack the cross-species reprogramming code. If they succeed, it could fundamentally change how conservation science approaches species recovery for generations.
For veterinary professionals, the implications of this work are not abstract. Understanding how cells from different species are reprogrammed has direct applications in comparative medicine, reproductive science, and the emerging field of conservation medicine. The Barcelona CryoZoo is not just saving species. It is building the scientific foundation for everything that comes next.
