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 AugustShe has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years

Q: Washington (CNN) Donald Trump's tax controversy and his self-destructive lack of discipline threaten to drain the Republican nominee of something he can't afford: time. With 36 days remaining before Election Day, the real estate mogul's campaign is consumed with the fallout from a New York Times story published over the weekend that found Trump reported a $916 million loss in 1995. That loss could mean Trump went 18 years without paying federal income taxes. Those findings -- which Trump's campaign isn't disputing but haven't been independently confirmed by CNN -- would be daunting for any presidential candidate to overcome. But they're especially challenging for Trump, who is losing control of the campaign's narrative after a strong September in which he narrowed the race with Hillary Clinton.Trump is losing control of the campaign's narrative after a strong SeptemberTime is dwindling for Trump to regain his grip on the campaign's message
