(Newser) – Giant panda Mei Xiang, whose first cub became an international superstar, is not pregnant, National Zoo officials said today. The panda, who was artificially inseminated in January, experienced her third false pregnancy in as many years, the Washington Post reports. Four-year-old Tai Shan, Mei Xiang's only cub to survive infancy, is scheduled to be handed over to the Chinese government later this year.
