Fighting panda extinction

Good news for lovers of the evolutionary dead-enders known as pandas:

ATLANTA - After seven years of trying and hoping, Zoo Atlanta officials announced a rare giant panda birth Wednesday, one of only a few in the United States.

Lun Lun delivered her first cub just before 5 p.m., zoo spokeswoman Jennifer Waller said. The zoo planned a news conference for later in the evening. ...

Zoo Atlanta artificially inseminated the 8-year-old Lun Lun at the end of March with semen taken from her partner, Yang Yang. They had tried for years to successfully mate the pair naturally.

But they had success time and time again in unsuccessfully mating the pair naturally.
