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

New input: ANCHORAGE, Alaska (CNN) -- Republican vice presidential candidate Sarah Palin's boast to have opposed the infamous "bridge to nowhere" is a staple of the Alaska governor's stump speech, but her record is more complicated than the one-liner. Alaska Gov. Sarah Palin canceled work on the Gravina Island bridge in 2007 after initially supporting the project. She repeated the line Tuesday in Lebanon, Ohio, telling supporters, "I told Congress, 'Thanks, but no thanks' for that bridge to nowhere up in Alaska. If our state wanted a bridge, we were going to build it ourselves." But Palin originally supported construction of the bridge, which would have linked the city of Ketchikan with its airport on sparsely populated Gravina Island.Gov.
