Hi, I'm Hayley with your Newsround update. Coming up:

And find out who Steve Backshall is talking about

He would break wind with enormous gusto.

First, a massive metal wall's been put up in the middle

Security costing ?50 million is in place as American President

Barack Obama, Germany's leader Angela Merkel and

British Prime Minister David Cameron are amongst

the world's most powerful people coming here next week.

But many think the safety measures are over the top.

This massive fence has gone up around Cardiff city centre, ahead of

the NATO Summit - a meeting of some of the world's most powerful people.

It's caused massive traffic jams here as people try

And some shop owners have said it's had an effect on trade.

But although it has caused problems for some people,

it is an important security measure for such a high-profile meeting.

They do have to secure the castle because of what is going on in the

world. Because Obama is coming. I think it is too imposing. It is like

a zoo! The castle is surrounded by a moat already.

World leaders like the American President will attend

They'll decide on how NATO, which is a military organisation made up of

lots of countries, will decide on how they respond to the situations

Local people don't have to worry too much - the fence will be coming down

The rush is on to find ?10,000 of gold that's been buried

in the sand on the south coast, and if you find it, you can keep it.

It's part of a three-month art festival.

They've hidden old watches to fool those with metal detectors.

I've got my shovel, I am going to do it. Any luck? Not yet. Are you

hopeful? Yes. A Galapagos tortoise that's 100

years old has been given The animal, which is extremely rare

and protected, lives in a zoo and He's used to scrapes with

the world's scariest animals, now Deadly 60's Steve Backshall is

off to the most extreme environments for his new series,

Deadly: Pole to Pole. But you sent him

some gruelling questions! Ruby asks, is the animal you still

haven't been able to film? The Jaguar was one we had been trying to

get, then succeeded. The one I haven't taped would be the snow

leopard, I have spent a lot of time researching, I have got, in the

night, I have been to within about three metres of one, I heard it

snarl. But I didn't manage to get a shot. Emily says, what is the

difference between venom and poison? Then is something that is

injected, poison is something that is ingested, you swallow it. If you

are going to drink something or eat something in order for it to affect

you, it is poison. For example, the skin secretions of a poison dart

frog work by an animal eating the frog. Chloe asks, what was the

funniest moment with an animal whilst working on the new show?

Working with mountain gorillas. He would break wind with enormous

gusto, and for quite an extended period of time. And you could just

see him sat over my shoulder just doing, I've got you! Will asks, how

much training does it take? I train constantly, even if I am out in the

field, or in the jungle, I still exercise for at least an hour every

day, which is essential because the things the job can throw at me, you

cannot predict them. So I make sure I am always in tiptop shape.

On Tuesday, we told you Shaun the sheep hadn't

had a haircut for six years after getting lost in Australia.

But now he's totally bald and has lost over three stones of wool.

He must be feeling the cold now then!

That's all from me, so have a great Friday,
