One Small Step From Man, One Giant Leap for Pandas: "BEIJING, April 28 -- Xiang-Xiang, a 4-year-old giant panda weighing in at about 180 pounds, hesitated for a few seconds on the misty slope, as if screwing up his courage, and then lumbered off through a forest of bamboo stalks to a new life in the wild.With his waddle to freedom Friday morning on a Sichuan province mountainside, specialists said, Xiang-Xiang became the first panda born in a laboratory from an artificially inseminated mother, raised in captivity in China and released into nature to fend for himself."
