:00:24. > :00:32.Hello there. Hayley and Sonali here. Here's some of what we've got lined
:00:32. > :00:37.up - the super rocket that could take people to Mars. Find out why
:00:37. > :00:41.laughter really could be the best medicine. First, rescuers are
:00:41. > :00:45.trying to save a group of miners trapped underground in South Wales.
:00:45. > :00:50.The men have been stuck all day after a drift mine collapsed in
:00:50. > :00:55.Swansea Valley this morning. Three men managed to escape, but police
:00:55. > :01:00.and Fire Services are trying to free four others. It's a difficult
:01:00. > :01:03.situation. It is dynamic. Everybody that needs to be there from the
:01:03. > :01:08.emergency services, including the mine rescue teams are there. We'll
:01:08. > :01:12.keep you updated on that. Prime Minister, David Cameron, is
:01:12. > :01:16.visiting Libya today. It's the first time such a senior leader
:01:16. > :01:20.from Europe or America has visited the country since Colonel Gaddafi
:01:20. > :01:23.was overthrown last month. Britain has been playing a major role in
:01:23. > :01:33.the military effort to support the rebel groups now trying to run the
:01:33. > :01:37.country, but there are still lots of questions that need answering.
:01:37. > :01:41.Three weeks ago, Libyan rebels trying to overthrow Colonel Gaddafi,
:01:41. > :01:46.entered Tripoli and took over his compound and the city. It was a
:01:46. > :01:49.massive moment for the country. The battle for Libya isn't over.
:01:49. > :01:56.Gaddafi supporters still control four areas of the country and the
:01:56. > :02:00.rebels say they need more weapons to help capture the spots. No-one
:02:00. > :02:04.knows where Gaddafi is. Most people think he's hiding somewhere in
:02:04. > :02:08.Libya. He's said he would rather die than leave the country. He
:02:08. > :02:12.built a network of underground tunnels in Tripoli, which he could
:02:12. > :02:17.have used to escape. There are loads of deserts so he could be
:02:17. > :02:21.anywhere. Some of his family have fled to Algeria and this week one
:02:21. > :02:28.of his sons went to Niger, also next door. Wherever he is, Gaddafi
:02:28. > :02:33.is still making his views heard. He keeps putting out messages on TV.
:02:33. > :02:35.David Cameron's visit today is a show of support for the new leaders,
:02:35. > :02:38.the National Transitional Council. Britain has been one of the
:02:38. > :02:44.countries heading the international operations to help build a new
:02:44. > :02:49.Libya. Colonel Gaddafi said he would hunt you down like rats, but
:02:49. > :02:54.you showed the courage of lions and we salute your courage. The rebels
:02:54. > :02:57.are led by this man, Mustafa Abdul Jalil. They have big plans. They
:02:58. > :03:01.want to create a new government by the end of the month and hold
:03:01. > :03:06.elections within eight months, but they don't have full control of
:03:06. > :03:13.Libya yet. They reckon Gaddafi is planning further attacks, so there
:03:13. > :03:23.is still a lot of work to be done. The design for a new rocket that
:03:23. > :03:23.
:03:23. > :03:28.could replace the shais shuttle and take -- space shuttle and take
:03:28. > :03:36.astronauts to Earth. They are hoping it will be ready for liftoff
:03:36. > :03:40.in six weeks' time. NASA aren't the only ones on the design trail - the
:03:40. > :03:45.shortlist for the new pylons are out. They haven't had a make-over
:03:45. > :03:51.for 90 years, so a competition was launched to come up with better
:03:52. > :03:58.designs. To staying safe on your way to and from school. Police in
:03:58. > :04:04.London say autumn is the worst time of year for children being robbed
:04:04. > :04:07.and having their mobile phones taken from them. Officers are
:04:07. > :04:12.running special patrols outside schools so you know how to avoid
:04:12. > :04:15.being a target. It's almost 8am in Sutton in south-west London and
:04:15. > :04:19.these officers are part of a crack team looking after the kids on
:04:19. > :04:24.their way to school. More than 1,000 officers around London have
:04:24. > :04:28.been put on special duty for the start of the new term. For the next
:04:28. > :04:33.few weeks, they'll travel on buses, patrolling the streets and offering
:04:33. > :04:37.advice on how to stay safe. Have either of you had unsafe moments on
:04:37. > :04:41.the way to school or back home? have. I've been on the bus once and
:04:41. > :04:46.there was a fight happening upstairs and I got really scared
:04:46. > :04:50.that maybe one of them would have come down and they would have been
:04:50. > :04:57.fighting downstairs and I would have been hurt. I've had a friend
:04:57. > :05:02.who has had something nicked. He had a phone and a teener asked him
:05:02. > :05:07.for it. He gave them the phone and then they ran off. Officers want to
:05:07. > :05:11.make sure that kids do as much as they can to avoid being robbed.
:05:11. > :05:15.Make sure you don't listen to your phone or MP3 player. Don't show
:05:15. > :05:20.your phone out and about and keep it on silent in your bag and if you
:05:20. > :05:24.feel unsafe on a bus, then move to another seat. If you are upstairs
:05:24. > :05:30.move down, or when the bus pulls to a stop, go and speak to the driver
:05:30. > :05:35.and if you feel unsafe then dial 999. If you are unlucky to have
:05:35. > :05:40.someone clock what you've got and say, "I want your phone", then what
:05:40. > :05:44.should you do? If someone has seen that you have a mobile phone, then
:05:44. > :05:51.hand it across. Don't try to challenge them. The police say they
:05:51. > :05:55.are working to cut crime, but they need your help to keep you safe.
:05:55. > :05:58.There's nothing funny about feeling ill, but scientists reckon if you
:05:58. > :06:07.have a laugh when you're sick it can take the pain away. We have
:06:07. > :06:11.been back to school in lesson in laughter yoga to fine out more.
:06:11. > :06:21.Watching your favourite CBBC characters can be pretty funny and
:06:21. > :06:21.
:06:21. > :06:23.now experts reckon having a laugh could actually be good for you.
:06:23. > :06:28.Researchers at Oxford University have been testing how much pain
:06:28. > :06:31.people can take. One of the ways that scientists tested it was to
:06:31. > :06:37.sit people down in front of TVs with ice packs on their arms. It
:06:37. > :06:46.doesn't take long for it to start to sting, but what they found was
:06:46. > :06:49.that people watching the funny clips felt the pain less. These
:06:49. > :06:55.guys know just how good a giggle can make them feel. It keeps me
:06:55. > :07:00.going for a while and it's good for your body. It's really fun I think
:07:00. > :07:04.it's good for other children to get along well with children and laugh.
:07:04. > :07:09.On average kids laugh more than 100 times a day, compared to just nine
:07:09. > :07:19.times for adults. If your mum and dad complain of a bad tummy or sore
:07:19. > :07:23.throat, why not do something silly? It might make them feel better. A
:07:23. > :07:28.latest list of Guinness World Records is out and it includes the
:07:28. > :07:32.world's longest finger nails and the most piercing on a face. The
:07:32. > :07:42.biggest tongue, that is long! Here's the biggest afro and we have
