Q: 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: (CNN) Saturday was a big day for Bernie Sanders' quest for the Democratic presidential nomination as he swept to resounding victories in the caucus states of Hawaii, Washington and Alaska. But the delegate math is still in Hillary Clinton's favor.

"We have a path toward victory." Takeaways from Western Saturday Clinton built up her delegate lead on the back of a strong run in the South, and Sanders argued Saturday his campaign always knew those states would be tough. In Madison, he said the map now offers more opportunities for his campaign as the contest progressed, largely because his wins are being powered by huge turnout among younger voters.Sanders hopes wins Saturday will help build momentum for larger states later onClinton has a commanding overall lead in delegates
