:00:00. > :00:08.Hello. You're live with CBBC this Wednesday morning. I'm Leah with all
:00:09. > :00:13.the latest from the Newsround team, including: Murray goes head to head
:00:14. > :00:15.with Federer for Aussie Open glory. And The mysterious beaver that's got
:00:16. > :00:26.scientists all confused. But first, peace talks aimed at
:00:27. > :00:29.bringing an end to the war in Syria will start today. The talks in
:00:30. > :00:33.Switzerland bring the Syrian government face to face with the
:00:34. > :00:36.opposition for the first time. More than 100,000 people have died in the
:00:37. > :00:41.conflict since 2011, which started when rebel groups tried to overthrow
:00:42. > :00:43.the country's president. Leading figures from around the world will
:00:44. > :00:55.oversea the talks, including Britain's Foreign Secretary William
:00:56. > :00:58.Hague. This is the opportunity for Syrian leaders on all sides to bring
:00:59. > :01:06.an end to this bloodshed, to save this country, to put an end to the
:01:07. > :01:10.extraordinary misery. Next, another winter storm has hit
:01:11. > :01:14.the east coast of America. Up to 12 inches of snow has fallen in parts,
:01:15. > :01:17.forcing lots of school to shut and thousands of flights to be
:01:18. > :01:20.cancelled. The snow has covered the streets of New York City and
:01:21. > :01:24.Washington DC is expected to get its heaviest snow fall in three years.
:01:25. > :01:27.This second storm has come just two weeks after the polar vortex brought
:01:28. > :01:34.heavy snow and freezing temperatures to the same area.
:01:35. > :01:37.Now, it's a big day for Andy Murray as the British number one takes on
:01:38. > :01:41.Roger Federer in the quarter finals of the one of the biggest tennis
:01:42. > :01:44.tournaments around - the Australian Open. Federer's won more grand slams
:01:45. > :01:48.than any current player, but Murray beat him in the semi-finals of this
:01:49. > :01:51.tournament this time last year. So Ayshah's been looking at who's
:01:52. > :01:54.likely to come out on top. Murray versus Federer is the chance
:01:55. > :01:59.for old rivals to meet again and a chance to see if both men are back
:02:00. > :02:01.to their best. A lot has been written about Murray's recent back
:02:02. > :02:09.surgery, but after four rounds of testing in Melbourne, his coach says
:02:10. > :02:13.he has no excuses. Even if he was really ready and he hadn't had any
:02:14. > :02:18.setbacks, you still never know what is going to happen. He could still
:02:19. > :02:23.lose the match easily, it doesn't really matter. Andy has had a good
:02:24. > :02:26.run in Miami. Many thought Federer's own back trouble and a disappointing
:02:27. > :02:30.2013 kept him stuck on 17 grand slam wins, but his partnership with
:02:31. > :02:36.Stefan Edberg may be the key to changing that. This match throws up
:02:37. > :02:48.more questions than it answers - no one, not even tennis superstars,
:02:49. > :02:55.knows what's going to happen. If it is warm, on the court, I go for
:02:56. > :02:58.Federer. I'm confident it will be married. He's not going to be
:02:59. > :03:03.physical, it is a match he knows he can win. Andy Murray has been saying
:03:04. > :03:06.that he doesn't expect to win the Australian Open, but he's also been
:03:07. > :03:11.saying that expectations can change, and if he can beat Roger Federer for
:03:12. > :03:13.the first time in a grand slam they certainly will.
:03:14. > :03:17.Well, that game starts in just under an hour, but Rafael Nadal's on court
:03:18. > :03:21.right now in his quarter final match against Bulgaria's Grigor Dimitrov.
:03:22. > :03:27.And he is just beating them by three sets to one. Earlier, in the women's
:03:28. > :03:29.quarter finals, defending champion Victoria Azarenka was beaten by
:03:30. > :03:32.Agnieszka Radwanska and Sloavkia's Dominika Cibulkova knocked out
:03:33. > :03:39.Simona Halep to make it through to the semi-finals.
:03:40. > :03:42.For the first time in over 30 years, Britain will have its biggest squad
:03:43. > :03:45.at the Sochi winter games next month in Russia. Three-time winter
:03:46. > :03:48.Olympian Chemmy Alcott has been selected, despite breaking her leg
:03:49. > :03:50.in 2012. There will be a record number of 19 skiers and
:03:51. > :03:53.snowboarders, including freestyle silver medallist James Woods. Former
:03:54. > :03:57.Olympic sprinter Craig Pickering will be part of the ten men who will
:03:58. > :04:01.make up two bobsleigh crews. Altogether, Team GB will have 56
:04:02. > :04:04.athletes at the games! Finally to the mystery beaver that's
:04:05. > :04:09.been caught on camera tucking into trees. A farmer in Devon set up this
:04:10. > :04:14.night-vision camera to find out what was causing the teeth marks in his
:04:15. > :04:17.the bark. He discovered it was this little fella, but experts are
:04:18. > :04:20.confused, because wild beavers are extremely rare in England after they
:04:21. > :04:32.were hunted to extinction during the 12th century. I'd seen something
:04:33. > :04:37.similar before in Canada, but I thought, no, we can't have anything
:04:38. > :04:42.like it be fair here, can we? So we decided to put out a camera on the
:04:43. > :04:48.site when I'd seen it nor the trees. And to our great surprise,
:04:49. > :04:52.yes, it was a beaver. Fantastic! That's it for now, but tune in in
:04:53. > :04:54.half an hour when we'll have news of this amazing ice palace and Man
:04:55. > :05:00.City's 9-0 win.
