Saving Animals, Cell by Cell

San Diego's “Frozen Zoo” is one of the world's largest collections of living animal tissue, collected from hundreds of species for research, conservation and even cloning. We talked to geneticist Oliver Ryder, one of the scientists who manage the Frozen Zoo. Also, a conversation with David Haussler, coordinator of the Genome 10K Project, which is using samples from the Frozen Zoo and other sources to map the genomes of 10,000 species.
