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: London (CNN) -- Cyber security is big news right now. It seems a new high-profile breach is reported almost daily and yet this represents only the very tip of the iceberg. Backed by a highly organized black market worth billions of dollars, cybercrime has grown exponentially in scale and sophistication in recent years. In the face of this mounting threat, government and industry are manning the defenses. But finding the right people to protect some of our most valuable data isn't straightforward and requires a new approach. Over the past three years I have competed in a unique set of security games, backed by UK government, industry, academics and professional bodies, known as the Cyber Security Challenge. This aims to find talented amateurs by testing their skills with realistic competitions.Stephen Miller is the reigning UK cyber security championMiller: Cybercrime has grown exponentially in scale and sophistication in recent yearsCybercrime is backed by a highly organized black market and is worth billions of dollarsCyber security is often regarded as hobby for young people rather than "genuine" career 
 Question:In my time playing the Challenge I have come face to face (or face to screen) with many dangerous viruses and computer code, and defended networks from simulated live-hacking attempts carried out by the _'s leading cyber defense experts.
