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: Washington (CNN) -- For both presidential campaigns, Republican Mitt Romney's choice of Wisconsin congressman and conservative star Paul Ryan as his running mate was like Christmas come early. Conservatives wanted one of their own on Romney's ticket and they got that in Ryan, who has emerged as their ideological leader on the Hill on fiscal and budget matters. The choice also helps satisfy Republican strategists who felt Romney needed to not only stress how President Barack Obama has failed in that role, but also better articulate what the GOP candidate would do if elected. "Ryan is a great choice. He energizes an already motivated party to a further degree and will help clarify the differing visions between the two campaigns for the country," said Phil Musser, a GOP strategist who in 2007 was a senior adviser to Romney's presidential campaign. "There are big choices, and in making the selection, Romney is showing that he believes America is ready for the choice."Both sides got what they wanted in Mitt Romney's choice of Paul Ryan as his running mateConservatives celebrate Ryan's selection; choice helps shore up some support for RomneyDemocrats quick to attack Ryan's selection as proof of Romney's conservative visionPolitical experts say both sides will battle over how to introduce Ryan to American public
