Hi, Martin here with your morning Newsround. On today's show. Why some

seaside mega cities are sinking, and the big surfer catching bigger

waves. But first to a question you might

have asked yourself from time to time - how different are you from

your brother or sister? Well, a new study says there might be more

between you than you'd think - and it's all based on when you were

born. Here's Leah with more. Whether you are a first-born, middle

child or the youngest, how hard you try at school could be down to what

position you hold in your family. A study suggests first-born children,

particularly girls, are more ambitious when it comes to studying

and going on to college or university. It also found there is

no difference between middle and youngest children. We asked you what

you think. If you need help with homework, there's always someone to

help you out. You are the oldest. Do you think you are smarter than your

sister? I think I am because she doesn't really like work as hard as

May. I think it is a stereotype. I don't think it is true. Who is

better at studying? My sister. Everybody is different. Not everyone

is the same. One of the apostle Paul reasons first-born is her so

ambitious could be down to mum and dad for. -- could be down to mum and

dad. Parents spent more time together with their child when the

first-born comes along. They are the only child. Whether you are a

first-born child or not, one thing never changes. Sibling rivalry. I

work harder than my sister. A new study that claims some of the

globes biggest cities are sinking. In some mega cities close to the

sea, scientists say the ground is going down ten times faster than the

water is rising. The research, which was presented by leading European

scientists, showed examples from Japan, Thailand and Indonesia. They

say more needs to be done to stop it.

Next to the space satellite found in the middle of a rainforest. A

fisherman in Brazil's Amazon region has found a large piece of debris

from a European space launch. The man said he found the metal object

floating on a remote river. It's believed to be debris from a launch

in a neighbouring country last summer.

To sport next, and a bit of a row brewing over a new British record.

Olympic champion Greg Rutherford recently set a new British best of

eight metres, 51 centimetres at an event in America. But the man who

previously jointly held the record - Chris Tomlinson - says it shouldn't

count because it was actually a foul leap that the officials missed Last

night Real Madrid thrashed Bayern Munich 4-0 in the Champions League,

to secure their place in the final. It is not a legitimate job. If we

are going to accept these marks, we are British athletics. We have two

must set an example. We have got to be above all this. If we are going

to set national records, these records have to be proper national

records set legitimately. Real Madrid are through to the Champions

League final. They beat Bayern Munich 4-0 last night. Tonight

Chelsea take on Atletico Madrid at Stamford Bridge.

You heard about wearing technology. What about a smart ring? The night

can be used to write a message is, read books and even control your TV.

It enables you to interact with anything around you. It has touched

all over. We have a touch slider, so when you slide you can play, change

of volume, change your challenge -- channel. And finally check out this

surfer riding waves in Portugal. American surfer Garrett McNamara

holds the world record for the largest wave ever ridden, and had a

go at riding these waves generated by a big boat in the Tagus River.

That's all from me, Newsround's back right here in about half an hour.
