From the National Zoo:

“The giant panda team at the Smithsonian’s National Zoo and Conservation Biology Institute has determined that Mei Xiang will not give birth this year.
The panda team has been monitoring Mei Xiang’s behavior and hormones very closely during the past weeks. The only way to definitively determine if a giant panda is pregnant before she gives birth is to detect a fetus on an ultrasound. Her hormones and behavior will mimic a pregnancy even if she is not pregnant. Scientists confirmed that a secondary rise in Mei Xiang’s urinary progesterone levels began July 28. This signaled that she would either have a cub or experience the end of a pseudopregnancy within 30 to 50 days. Her hormones returned to baseline levels Sept. 14, but she did not give birth, indicating she was either experiencing a pseudopregnancy or did conceive but resorbed the embryo.”

At least we have that baby tiger to console us. Damn it!! Fortunately we’ll always have 99 Luftballons to get us through the days:
