Problem: 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

Problem: Photos of US ambassador to South Korea Mark Lippert meeting with the country's leaders have emerged for the first time since the envoy was attacked by a knife-wielding pro-North Korean activist. Lippert is recovering at Severance Hospital in Seoul, and was able to meet with US Navy Admiral James Winnefeld as well as members of South Korea's ruling and opposition parties. Police are charging the activist, Kim Ki-jong, 55, with murder after he slashed the ambassador while screaming demands for Korean reunification. The attack Thursday on Lippert, at a forum about reunification, prompted rival North Korea to gloat about 'knife slashes of justice,' that left deep gashes and damaged the ambassador's tendons and nerves.Ambassador Mark Lippert injured in a surprise attack at a breakfast meetingKim Ki-jong, a 55-year-old anti-US activist, was immediately arrestedPolice seeking three charges in attack, including attempted murderDoubts over whether he carried out attack alone or was part of conspiracyKim has visited North Korea several times and had books from the countryLippert needed 80 stitches for slash to his face and may have nerve damageHe could be discharged from hospital Wednesday after stitches removed
