In comes Doctor number 12

Doctor Who star Matt Smith is to leave his role as the Doctor at the end of this year, the BBC has announced. Smith first stepped into the Tardis as the 11th Doctor in the New Year's Day episode of 2010. Taking over from David Tennant, he was the youngest actor to play the role. But after four years as the Time Lord, viewers will see Smith's Doctor regenerate in the 2013 Christmas special. But enough about that because almost 1 in 10 secondary students believe tomatoes grow underground, according to a new survey conducted by the British Nutrition Foundation (BNF). Over 27,000 students who were between the ages of 5 and 16 were given the survey by the BNF. After looking through the results, the foundation firmly believes that more education on healthy cooking and eating needs to be given out. There also needs to be more education on where each foodstuff comes from (and no, it's NOT the supermarket) because also recorded in the survey, primary students in the UK think cheese comes from plants and a quarter of them think fish sticks are made from chicken or pigs. I mean, seriously, I know they're just kids but fish sticks are called fish sticks for a reason. Nineteen percent of participants did not know potatoes grew underground, while 10 percent of them thought they grew on either bushes or trees. Speaking of stuff that doesn't grow on trees, Chinese currency and U.S. dollars are being used more widely than ever in North Korea instead of the country's own money, a stark illustration of the extent to which the leadership under Kim Jong-un has lost control over the economy. The use of dollars and Chinese yuan, or renminbi, has accelerated since a disastrous revaluation of the North Korean won in 2009 wiped out the savings of millions of people. This is just like what happened in Zimbabwe four years ago, so Kim Jong-un better sort out the mess his predecessors dug their nation into because the growing use of foreign currency is making it increasingly difficult for Pyongyang to implement economic policy, resulting in the creation of a private economy outside the reach of the state that only draconian measures could rein in. Also, North Korea is one of the most closed countries in the world, so it is difficult to determine what impact this could ultimately have on Kim's regime.
