:00:00. > :00:12.Good morning. I'm Leah with your Monday morning Newsround. Coming up
:00:13. > :00:16.in the next few minutes: The spacecraft being woken up to chase a
:00:17. > :00:26.comet! And Andy Murray surges into the Australian Open quarterfinals.
:00:27. > :00:28.-- he is just about to make it through to the quarterfinals. First,
:00:29. > :00:32.there have been violent clashes in Ukraine's capital Kiev overnight. A
:00:33. > :00:35.rally of thousands in the city's Independence Square turned ugly as
:00:36. > :00:39.anti-government protestors fought with riot police. The government
:00:40. > :00:43.there has introduced new laws which the protesters say restrict their
:00:44. > :00:47.freedom. Ukraine has been divided in recent times over whether it should
:00:48. > :00:50.have closer ties with Russia, orthe rest of Europe. Authorities have now
:00:51. > :00:56.said they'll begin talks to try and sort things out. Next, to one of the
:00:57. > :00:59.most daring space missions ever attempted - to land on a comet. The
:01:00. > :01:03.Rosetta spacecraft has been hibernating in deep space for two
:01:04. > :01:07.and a half years, to save energy. But this morning, it will be woken
:01:08. > :01:11.up to chase after a comet - a huge lump of ice and rock hurtling
:01:12. > :01:16.through space. The plan is to land onto the comet to find out more
:01:17. > :01:25.about it. Nothing like this has been tried before. We are excited about
:01:26. > :01:30.landing on the comet. And analysing what it is made of. That is because
:01:31. > :01:33.comets are like time capsules. They contain the earliest water and
:01:34. > :01:40.organic material before the planets formed. Should energy drinks be
:01:41. > :01:43.banned from schools? There's a fresh warning about them from a top
:01:44. > :01:46.government adviser on school food. John Vincent thinks the mix of sugar
:01:47. > :01:50.and caffeine can damage children's concentration and health. He is
:01:51. > :01:54.calling for more work into the effects of the drinks. One school in
:01:55. > :01:57.Manchester is so worried, it has banned from its pupils from having
:01:58. > :02:00.them. We want to know what you think about this. Should high-energy
:02:01. > :02:07.drinks be banned from schools? Head to the website and tell us. Andy
:02:08. > :02:12.Murray looked to be easing into the quarterfinals of the Australian Open
:02:13. > :02:16.as he plays the lowest ranked player left in the tournament, Stephane
:02:17. > :02:22.Robert. He made short work of the first two sets, taking 25 minutes to
:02:23. > :02:28.take the first set, 6-1. The second set followed in similar fashion. It
:02:29. > :02:40.is now proving more of a fight and the Frenchman leads, 6-5. In
:02:41. > :02:42.football, Chelsea made a 3-1 win over Manchester United look easy at
:02:43. > :02:45.Stamford Bridge. Cameroon striker Samuel Eto'o scored his first
:02:46. > :02:48.hat-trick for the club, to take Chelsea to within two points of
:02:49. > :02:52.leaders Arsenal. United had their captain Nemanja Vidic sent off in
:02:53. > :02:55.stoppage time. Despite all of that, United manager David Moyes is
:02:56. > :02:57.keeping positive. We showed a lot of good things today and we have two
:02:58. > :03:02.try to improve. There is a progress we have to make. Myself and the club
:03:03. > :03:06.will try to do that. There were two more goals for Emanuel Adebayor as
:03:07. > :03:09.Tottenham won 3-1 at Swansea. The win lifted Spurs to fifth, with
:03:10. > :03:17.Swansea just two points away from the relegation zone. Just how great
:03:18. > :03:20.is your imagination? Could you create a world as magical as
:03:21. > :03:23.Hogwarts, or as funny as The Dumping Ground? If the answer is yes, then
:03:24. > :03:27.the 500 words short-story writing competition is back. If you are 13
:03:28. > :03:34.or under and fancy taking part, take a look at this. I am Chris Evans.
:03:35. > :03:39.You might have seen me on the telly's The One Show, or heard me on
:03:40. > :03:42.the radio. But if you have not, stick around. I have something
:03:43. > :03:45.exciting to tell you about. It is the 500 Words short story writing
:03:46. > :03:51.competition, open to anybody in the UK aged 13 or under. You have to
:03:52. > :03:57.make up a story using no more than 500 words. I love great ideas and
:03:58. > :04:02.that is what writing is all about, because when you tell a story, you
:04:03. > :04:14.bring ideas to life. What story will you write? You can write any type of
:04:15. > :04:23.story. A horror story. Or a love story. Perhaps set in the future

:04:30. > :04:34.mistaken for somebody else. It really is up to you. We want to see
