:00:25. > :00:30.We are live and we have got all the news you need to know. There is no
:00:30. > :00:34.other show it like Newsround. We have got Ore and Leah to break down
:00:34. > :00:38.the top stories. Sonali has got all the talk as the Winter Youth
:00:38. > :00:44.Olympics come to a close. I look at the techniques sports scientists
:00:44. > :00:48.are using to help Team GB win medals. First, to a row about how
:00:48. > :00:52.much money poorer families should get from the government to live on.
:00:52. > :00:56.They want to cut the amount Britain spent on benefits, the money people
:00:56. > :00:59.can get if they are sick or out of work. They want to make the system
:00:59. > :01:03.fairer it so people don't get more money from benefits than actually
:01:03. > :01:07.going to work, but some people say the changes could call real
:01:07. > :01:11.suffering two children. A lot of stories on the news have been all
:01:11. > :01:15.about money, it is kind of important. How much money does a
:01:15. > :01:19.family actually need to live on, and how much should people be given
:01:19. > :01:25.if they hit hard times? Today the government is trying to change the
:01:25. > :01:28.law to stop any family from being given more than �500 per week or
:01:28. > :01:33.�26,000 a year in benefits. The same amount of money an average
:01:33. > :01:35.working family would make. For modern benefits system was
:01:35. > :01:39.introduced after the Second World War to do something about the huge
:01:39. > :01:43.numbers of people living in poverty. The idea was that the government
:01:43. > :01:47.took money from everyone's taxes and gave it to people who became
:01:47. > :01:50.sick and couldn't work all lost their jobs. Before the system
:01:50. > :01:54.people could go homeless or hungry if they couldn't work, so the
:01:54. > :01:59.system made life much better for a lot of people. Britain spends more
:01:59. > :02:04.on benefits than anything else, �192 billion. The government thinks
:02:04. > :02:07.that is too much. They say the system isn't right because some
:02:07. > :02:10.people can earn more money by not working staying at home and
:02:10. > :02:15.claiming benefits and the good from getting a job. The government says
:02:15. > :02:21.it isn't fair on the people who do work and pay taxes. That is why
:02:21. > :02:24.they want to stop families getting more than �500 per week in benefits
:02:24. > :02:28.but charities say changing the law would mean some families would have
:02:28. > :02:32.to leave their homes and kids in bigger families would be worse off.
:02:32. > :02:36.The House of Lords is debating the changes today. If the government
:02:36. > :02:42.gets its way the new measures would come into force in 2013. Even if
:02:42. > :02:47.they are defeated they are unlikely to try to stop changing the way
:02:47. > :02:50.people out of work are helped. You may have caught the start of her
:02:50. > :03:00.incredible journey earlier but Blue Peter's leading lady has finally
:03:00. > :03:01.
:03:01. > :03:06.done it. Allen's goal to's 500 mile expedition is over. -- Helen
:03:06. > :03:11.Skelton. She has become the first person to use a bike as part of her
:03:11. > :03:16.expedition to the South Pole. Here is how she sounded when she made it.
:03:16. > :03:22.It has definitely been a tough way to live, we came here on 23rd
:03:22. > :03:26.December, camping and cookie in temperatures as low as -48,

:03:32. > :03:36.When you meet people through Sport Relief you realise it puts things

:04:06. > :04:14.How are you feeling? We came here hoping to win a medal and we got
:04:14. > :04:20.silver, we are really pleased. feels amazing to be taking part,
:04:20. > :04:24.great to get a medal. 10 days of action-packed competition. Closing
:04:24. > :04:28.ceremony going on behind us. Are you feeling a little bit emotional?
:04:28. > :04:32.It is release that it has come to a close. We spent over a week here in
:04:32. > :04:35.Innsbruck, had the time of our lives, and said to be leaving.
:04:35. > :04:38.Loads of your team-mates had been telling me it has been the best
:04:38. > :04:43.week of their lives, even if they haven't done as well as they wanted
:04:43. > :04:48.to. I don't think you will experience anything like this again.
:04:48. > :04:51.Even if we go to the senior games it will be totally different again.
:04:51. > :04:58.It has been amazing. Congratulations on being the first

:05:14. > :05:17.Olympics are training for the biggest event of their lives. To
:05:17. > :05:23.get them over the line they will need all the help they can get. We
:05:23. > :05:29.have been looking at the science behind the sport. The 2008 Beijing
:05:29. > :05:34.Olympics. Teme GP's best performers for 100 years. It is not just the
:05:34. > :05:40.people on the podium he worked hard. -- Team GB. It isn't just about
:05:40. > :05:44.spending hours in a gym on Europe, baroque whole team of people behind
:05:44. > :05:48.every athlete. They are called sports scientists and they are
:05:48. > :05:54.putting me through my paces. are about to a maximum treadmill
:05:54. > :05:59.test, to exhaustion, go as long as carp -- and hard as you can. At the
:05:59. > :06:03.last Olympics �245 million was spent on making our athletes fitter,
:06:03. > :06:09.faster and stronger. Lot of money were spent in facilities like this
:06:09. > :06:13.one in Preston. Your last three seconds, come on. This time �330
:06:13. > :06:17.million are being poured into our hopeful are Olympians at
:06:17. > :06:23.Paraolympians. Superb. This ultra fitness test measures of how well
:06:23. > :06:27.your heart, lungs work under pressure. Another test uses a 3 D
:06:27. > :06:31.modelling system to see how good your running technique is. Mine
:06:31. > :06:40.couldn't -- could do with some improvement. You can tell Baston
:06:40. > :06:45.out of information, but you can't account for talent. We try to
:06:45. > :06:49.redress the 1% of the 2% change in performance that could make all the
:06:49. > :06:53.difference between the gold or silver medal. In exchange for
:06:53. > :06:58.record levels of funding athletes have been set a goal to finish in
:06:58. > :07:04.the top four, and won more medals in more sports so it is game on for
:07:04. > :07:08.our teams and a sports scientist behind him. Great effort. Finally,
:07:08. > :07:12.Chinese New Year started today, the Of the Dragon, but it might not be
