Hi, I'm Ricky with all your top stories this Friday afternoon.

Coming up on Newsround...

Hi, Newsround, we're the Brownlee brothers.

Keep watching to find out more about us.

And find out why these sheep have turned the colour orange!

They are one of the most famous pairs of siblings

in the world of sport -

British triathlon stars Jonny and Alistair Brownlee.

The duo won silver and gold at the Rio Olympics last month

and hit the headlines this week when Alistair showed

his brotherly love by helping an exhausted Jonny over the line

during a race in Mexico.

Well, the Brownlees have been telling Newsround

their childhood memories as brothers.

Alistair and Jonny, thank you so much for coming into Newsround.

Now, we all know that you are brothers,

we want you to share some of your childhood memories,

so, guys, tell us about a time when you helped each other as kids.

Well, I think I was always helping him as a kid, really,

being the older brother.

I was trying to at least, and I remember one time

we were playing in a stream, we were dam building or something,

and he cut his finger open,

and blood just went everywhere in the stream.

And I held it and obviously took him back to my mum and dad,

and he was taken to hospital.

There it is, he has always been looking after me!

What about you? When you have helped him out as a brother?

I am the younger one, so he is supposed to help me out.

Oh, that one time we cycled to school,

I had an exam, and we swapped bikes.

We used to cycle to school in the morning,

one-time Alistair got a puncture,

and he said, "Here is my bike, I've got an exam, fix it."

It was a GCSE or something.

I was about an hour late to school, so that is when I helped him out.

Tell us about a time when you competed against each other as kids.

We competed against each other all the time as kids,

you know, everything in the garden became a massive competition,

when we play football or badminton

or cricket or having a race somewhere on a bike.

We'd do all sorts of little challenges like that.

Everything was a competition, so Monopoly, badminton,

table tennis in the garden, even when it comes to sledging,

the fastest one downhill, who can build the biggest snowman?

Everything you can compete at, we competed at.

Alistair, Jonny, thank you so much for that,

it's been great having you on Newsround.

That all right, thank you very much for having us. Thank you.

Gold and silver for the Brownlee brothers!

Go online to watch Newsround's special, Brothers And Sisters,

to hear some incredible stories

of sibling relationships from children all over the world.

A British man who spent three days living as a goat in the Alps

has won a special prize for his work.

Thomas Thwaites had prosthetic legs made so he could walk on all fours

and graze with other goats in the mountains.

He said he wanted to take a break from human life.

His research has now been given an Ig Nobel prize,

which is awarded for funny science projects.

From using science to some mad inventions -

have you ever wished

you could create a machine to make life a bit easier,

to make you your toast or pour your glass of orange juice?

Well, that is exactly what this man from New York in America does,

as I've been finding out.

He's invented a machine for just about everything.

Joseph Herscher has been making crazy inventions

since he was a child.

I made my first machine when I was five years old,

and it was a machine to store my candy.

Obviously, very useful for a five-year-old.

But also I noticed that it made my parents laugh,

and that sort of encouraged me to keep making more and more machines.

Videos of his wacky inventions have been huge hits online,

and now he spends all day making machines.

His contraptions are usually to help him out with everyday problems.

In

In the

Often I notice when things annoy me in day-to-day life,

"What can I do that will stop that from annoying me?"

But Joseph doesn't just solve problems with his machines -

he likes to have fun, too.

The machines that I make, they're as playful as possible,

and that doesn't make any sense, right?

But at the same time humans are naturally playful creatures,

and so we are drawn to the idea of a playful machine.

Well, something that Joseph hasn't got around to inventing

is orange sheep.

Yes, your eyes are not tricking you - these sheep are really orange.

A farmer in Cumbria in north-west England has decided

to spray-paint his flock.

Why? To put off thieves from taking them.

The paint is not harmful,

and the sheep have become a tourist attraction already.

What a bright idea!

That's all from me, Newsround is back on CBBC

tomorrow morning at 8:55am. Have a great evening!
