:00:00. > :00:12.Hi, Martin here with your morning Newsround. On today's show. Why some
:00:13. > :00:13.seaside mega cities are sinking, and the big surfer catching bigger
:00:14. > :00:25.waves. But first to a question you might
:00:26. > :00:27.have asked yourself from time to time - how different are you from
:00:28. > :00:34.your brother or sister? Well, a new study says there might be more
:00:35. > :00:41.between you than you'd think - and it's all based on when you were
:00:42. > :00:45.born. Here's Leah with more. Whether you are a first-born, middle
:00:46. > :00:53.child or the youngest, how hard you try at school could be down to what
:00:54. > :00:57.position you hold in your family. A study suggests first-born children,
:00:58. > :01:00.particularly girls, are more ambitious when it comes to studying
:01:01. > :01:05.and going on to college or university. It also found there is
:01:06. > :01:12.no difference between middle and youngest children. We asked you what
:01:13. > :01:20.you think. If you need help with homework, there's always someone to
:01:21. > :01:25.help you out. You are the oldest. Do you think you are smarter than your
:01:26. > :01:32.sister? I think I am because she doesn't really like work as hard as
:01:33. > :01:40.May. I think it is a stereotype. I don't think it is true. Who is
:01:41. > :01:49.better at studying? My sister. Everybody is different. Not everyone
:01:50. > :01:51.is the same. One of the apostle Paul reasons first-born is her so
:01:52. > :01:59.ambitious could be down to mum and dad for. -- could be down to mum and
:02:00. > :02:03.dad. Parents spent more time together with their child when the
:02:04. > :02:08.first-born comes along. They are the only child. Whether you are a
:02:09. > :02:13.first-born child or not, one thing never changes. Sibling rivalry. I
:02:14. > :02:22.work harder than my sister. A new study that claims some of the
:02:23. > :02:26.globes biggest cities are sinking. In some mega cities close to the
:02:27. > :02:30.sea, scientists say the ground is going down ten times faster than the
:02:31. > :02:32.water is rising. The research, which was presented by leading European
:02:33. > :02:37.scientists, showed examples from Japan, Thailand and Indonesia. They
:02:38. > :02:40.say more needs to be done to stop it.
:02:41. > :02:44.Next to the space satellite found in the middle of a rainforest. A
:02:45. > :02:48.fisherman in Brazil's Amazon region has found a large piece of debris
:02:49. > :02:52.from a European space launch. The man said he found the metal object
:02:53. > :02:55.floating on a remote river. It's believed to be debris from a launch
:02:56. > :03:03.in a neighbouring country last summer.
:03:04. > :03:06.To sport next, and a bit of a row brewing over a new British record.
:03:07. > :03:09.Olympic champion Greg Rutherford recently set a new British best of
:03:10. > :03:13.eight metres, 51 centimetres at an event in America. But the man who
:03:14. > :03:16.previously jointly held the record - Chris Tomlinson - says it shouldn't
:03:17. > :03:20.count because it was actually a foul leap that the officials missed Last
:03:21. > :03:26.night Real Madrid thrashed Bayern Munich 4-0 in the Champions League,
:03:27. > :03:31.to secure their place in the final. It is not a legitimate job. If we
:03:32. > :03:36.are going to accept these marks, we are British athletics. We have two
:03:37. > :03:39.must set an example. We have got to be above all this. If we are going
:03:40. > :03:47.to set national records, these records have to be proper national
:03:48. > :03:51.records set legitimately. Real Madrid are through to the Champions
:03:52. > :03:55.League final. They beat Bayern Munich 4-0 last night. Tonight
:03:56. > :04:06.Chelsea take on Atletico Madrid at Stamford Bridge.
:04:07. > :04:14.You heard about wearing technology. What about a smart ring? The night
:04:15. > :04:24.can be used to write a message is, read books and even control your TV.
:04:25. > :04:29.It enables you to interact with anything around you. It has touched
:04:30. > :04:41.all over. We have a touch slider, so when you slide you can play, change
:04:42. > :04:44.of volume, change your challenge -- channel. And finally check out this
:04:45. > :04:47.surfer riding waves in Portugal. American surfer Garrett McNamara
:04:48. > :04:51.holds the world record for the largest wave ever ridden, and had a
:04:52. > :04:56.go at riding these waves generated by a big boat in the Tagus River.
:04:57. > :05:01.That's all from me, Newsround's back right here in about half an hour.
