Using Virtual Reality to Save the White Rhino

There are four northern white rhinoceroses left in the world. Will a 360-degree documentary help us preserve them?
In the basement of the San Diego Zoo’s laboratory complex sits a four-foot-tall, liquid nitrogen-cooled aluminium canister. This “Frozen Zoo,” as the container is known, contains thousands of skin samples taken from a cornucopia of endangered animals, including those of the northern white rhinoceros, a subspecies that is perilously close to extinction. Only four such animals are left in the world. A genetic rescue team at the zoo is working to transform the frozen cells into stem cells that can be used to create the sperm and eggs necessary to grow a new generation of rhinos through in-vitro fertilization.
