One example: 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

Now, solve this: WASHINGTON (CNN) -- President Obama on Friday resumed -- with expanded legal protections -- the Bush administration's controversial system of military trials for some Guantanamo Bay detainees. President Obama says the commissions are OK, "provided that they are properly structured and administered." On the heels of Obama's shift this week to block the release of photos showing prisoners allegedly being abused by U.S. personnel in Iraq and Afghanistan, the military commissions announcement further infuriated the president's most ardent supporters while winning cautionary praise from some of his political foes. Obama said he supports the idea of the military commissions but opposes the version of the law that had been governing such trials in recent years: the Military Commissions Act put in place under the Bush administration in 2006, but subsequently struck down as unconstitutional by the Supreme Court.Obama revives Bush system that was suspended in JanuaryNew system to include expanded due-process rights for the suspects, Obama saysACLU calls move "a striking blow to due process and the rule of law"
