:00:00. > :00:11.Hey, Martin here with your final update of the morning. Coming up...
:00:12. > :00:14.The truth behind why you and your siblings are so different.
:00:15. > :00:31.Plus, the power to control your TV, tablet or phone at your fingertips.
:00:32. > :00:34.This is Newsround. But first to a sporting row over
:00:35. > :00:37.whether a new British athletics record should be allowed to stand.
:00:38. > :00:41.Olympic champion Greg Rutherford recently set a new British best in
:00:42. > :00:44.the long jump at an event in America. But rival Chris Tomlinson -
:00:45. > :00:47.who previously jointly held the record - says it shouldn't count. He
:00:48. > :00:52.claims Greg's foot was over the line and the jump was actually a foul.
:00:53. > :00:59.The judges say it was fair but Chris wants it looked at.
:01:00. > :01:05.It is not a legitimate jump. If we are going to accept these marks, we
:01:06. > :01:13.are British athletics and we have to set an example. We have to be above
:01:14. > :01:22.all this. These records have to be proper national records set
:01:23. > :01:26.legitimately. Now, how different are you from your brother or sister?
:01:27. > :01:30.It's a question you might have asked yourself and a new study says there
:01:31. > :01:33.might be more between you than you'd think. And it's all based on when
:01:34. > :01:39.you were born. Here's Leah with more.
:01:40. > :01:42.Whether you are first-born, middle child or the youngest, how you
:01:43. > :01:49.perform make me down to what position you are in your family. A
:01:50. > :01:54.study suggests first-born children are more ambitious when it comes to
:01:55. > :01:59.studying and going to university. But it also found that there was no
:02:00. > :02:02.difference between middle and youngest children. We thought we
:02:03. > :02:08.would ask you what you think of your siblings. If you need help with your
:02:09. > :02:14.home work then there is someone to help you out. You are the eldest, do
:02:15. > :02:23.you think you are smarter than your sister? I think I am because she
:02:24. > :02:28.doesn't work as hard as me. I think it is just a stereotype. Who is
:02:29. > :02:37.better at studying? You or your sister? My sister. Everyone is
:02:38. > :02:47.different. Not everyone is the same. One of the possible reasons is --
:02:48. > :02:54.could be down to mum and dad. Parents spend more time together
:02:55. > :03:00.with the first child because they are the only child at that moment.
:03:01. > :03:05.But whether you are first-born or not one thing never changes, sibling
:03:06. > :03:17.rivalry. I work harder than my sister.
:03:18. > :03:21.To other news from around the world now and a new study that claims some
:03:22. > :03:24.of the globe's biggest cities are sinking. In some mega-cities close
:03:25. > :03:28.to the sea, scientists say the ground is going down ten times
:03:29. > :03:30.faster than the water is rising. The research, which was presented by
:03:31. > :03:33.leading European scientists showed examples from Japan, Thailand and
:03:34. > :03:36.Indonesia. They say more needs to be done to stop it.
:03:37. > :03:40.To the latest in wearable technology next and the power to control all
:03:41. > :03:44.your gadgets using just one finger. Well, well sort of. This is the Nod,
:03:45. > :03:48.a high-tech ring that can be used to write air messages, read books on a
:03:49. > :03:52.big screen, send texts and even control your TV. It'll set you back
:03:53. > :03:57.almost ?90 but the man behind it is pretty excited about what it can do.
:03:58. > :04:03.Nod enables you to enact with anything around you. We have a
:04:04. > :04:11.slider. You can slide your visitation or your music. You can
:04:12. > :04:22.play, pause, change the volume or channel. Next to the space satellite
:04:23. > :04:24.found in the middle of a rainforest.
:04:25. > :04:28.A fisherman in Brazil's Amazon region has found a large piece of
:04:29. > :04:31.debris from a European space launch. The man said he found the metal
:04:32. > :04:34.object floating on a remote river. It's believed to be debris from a
:04:35. > :04:38.launch in a neighbouring country last summer. And you can see a
:04:39. > :04:41.special picture gallery of how that satellite was discovered over on the
:04:42. > :04:45.Newsround website right now. That's also where you can check out news on
:04:46. > :04:51.the latest Xbox launch and the details of the cast for the new trio
:04:52. > :04:55.of Star Wars movies. And finally, how do you go surfing
:04:56. > :04:58.when you've got no waves? Make your own of course. American surfer
:04:59. > :05:01.Garrett McNamara had a go at riding these artificial waves in Portugal.
:05:02. > :05:02.They were generated using a special
