WATCH: Technology that could potentially bring animals back from extinction.


On “TechKnow,” Phil Torres traveled to the San Diego Zoo Safari Park to get a closer look at a different kind of zoo—a collection of cell cultures stored in giant freezers. Known as the “Frozen Zoo,” this conservation project hopes to preserve thousands of endangered species for research and to potentially engineer future generations.

Though genetic rescue, northern white rhino cells stored at the Frozen Zoo could be used to create healthy future generations. Advances in stem cell research have yielded positive results in mice populations, allowing scientists to create individual egg and sperm cells from stem cells taken from the mice.
