Curators at the Cincinnati Zoo announced the birth of the world's first test-tube gorilla. In March, researchers removed 12 eggs from Rosie, a gorilla at the zoo, and fertilized them with sperm from a gorilla at Omaha's Henry Doorly Zoo. Seven months later, Rosie the gorilla became the proud parent of the two-pound female western lowland gorilla. Five other embryos that resulted from the fertilizations will be shipped to zoos around the U.S. in an effort to boost the population of gorillas in captivity.
