Example input: For four years we have waited expectantly for the pitter patter of tiny paws. Soon, that wait could finally be over. Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as August.

Q: Hong Kong (CNN) -- Hong Kong's busy harbor is never short of action, but the great big yellow duck that floated into town on Thursday captured the city's attention.

For two weeks local media has been on something of a "duck watch," closely monitoring the movements of the 16.5-meter (54 feet) inflatable sculpture. The man behind the seriously over-sized bath toy, Dutch artist Florentijn Hofman, described the Hong Kong response as overwhelming and said he was happy to have finally made it to the city, his first visit.Rubber duck is six stories tallWill be on display in Hong Kong until June 9Next stop ... the United States
