China has two little bundles of giant panda joy on the ground, twin cubs who were born yesterday to Haizi at the China Conservation and Research Center for the Giant Panda in Sichuan province. One cub is female, notes the AP, and weighs in at a not-so-hefty 2.79 ounces. Mama bear is still hanging onto her sibling; the two were born 10 minutes apart. Pandas are notoriously horrible at procreation, though China's breeding programs enjoy some success. (More panda stories.)
