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: Concerns about westerners joining the fight in Syria dominated the annual Aspen National Security Forum with top U.S. government officials equating the threat from the stalemated Syrian civil war to that posed by al Qaeda's Yemen affiliate. Michael Vickers, the Pentagon's undersecretary for intelligence, said there are now believed to be thousands of western passport holders, many with easy visa access to enter the United States, who are among foreign fighters in Syria. California man arrested, said he wanted to join ISIS John Carlin, the Justice Department's national security chief, called the threat "unprecedented" and said the department is putting resources to prosecute Americans who try to travel to the region to join terror groups involved in the war.Annual Aspen Security Conference brings together top national security figuresDiscussion tends to trend toward current eventsTSA administrator says improvised explosives more of a concern than shoot-downsThere might be a less-publicized reason that 2009 underwear bomb didn't detonate
