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: Washington (CNN) -- President Barack Obama will defend his foreign policy Wednesday in a commencement address at the U.S. Military Academy at West Point and lay out an interventionist, but not over-reaching plan, White House officials say. The speech comes amid stinging criticism of the President's foreign policy following a trip to Asia last month. Obama, who has carefully avoided mentioning any sort of military confrontation in his responses to the challenges in Syria and Ukraine, hit back at his critics, saying his goal is to avoid costly "errors" on the world stage. But the world waits for no man. Obama may advocate a risk-averse foreign policy, but he has a series of pressing global challenges which are likely to dominate the remainder of his term.
