It's 8:15am on Wednesday the 5th of April.

You're watching Newsround with me, Jenny.

Keep watching.

For one big gem, this record-breaking pink diamond.

And it's a small world after all.

The planet's landmarks built in miniature.

First, we're talking about this.

It might not look like much, but this little packet of nut paste

is helping to save thousands of children's lives around

the world right now.

It's helping kids who don't have enough to eat.

One place they are being used is South Sudan, in Africa,

where a famine has been declared.

BBC reporter Anna Foster sent us this.

This is a special nutrition centre where mums bring their babies

and just over there they are being weighed and they have a special tape

that goes round the baby's arm to see whether or not

it is malnourished.

This area is called Unity State.

It is about the size of Manchester.

290,000 children are severely malnourished and need serious help,

and they come to places like this to get it.

There are a lot of special things that can be given to the children

when they have had not enough to eat that really helps

improve their health.

Emily is from Unicef.

What you are holding here is something, it looks really

small in a packet but this can save a child's life.

It can.

This is a package of nuts, oil and milk, and essentially

what this does is it nourishes the baby really quickly so a child

will take this for about a week.

You can see the difference in a couple of days.

They put their weight back on and it completely changes their appearance.

It is a bit of a miracle food really.

Yeah.

This would be the same as a meal, would it?

Exactly.

They can take between one and three a day between seven and 14 days

and this will completely transform the children that are

severely malnourished.

This is really special stuff.

You can see some of the children taking it.

A box is about ?60.

Every box saves a child's life in South Sudan.

Thanks, Anna.

You can find out more about the crisis in South Sudan,

and why it's happening, in our guide at Newsround online.

In other news, it was Zlatan Ibrahimovic who saved the day

for Manchester United at the last minute and rescued a point

against Everton last night.

He scores.

This 94th-minute penalty, in injury time, meant United drew 1-1,

following a first-half goal from Phil Jagielka.

The result means the Red Devils stay fifth in the table.

It's an amazing run of 20 matches unbeatable,

but too many draws at home.

Because of that we are in the position we are

because we have the spirit, the defensive organisation.

We build well.

Not today.

We did not create a lot today.

We do not score enough goals.

Next to a man who's set a big goal for himself,

to cycle around the world in 80 days.

Watch this.

If there's one thing this guy loves it's riding his bike.

But he's not one for a leisurely cycle, oh no, Mark Beaumont wants

to be in the record books.

In 2008, he cycled around the world in 194 days

and set a new world record.

His next adventure took him from Alaska in North America

to Argentina in South America.

And in 2015 he cycled the length of Africa from Cairo

to Capetown in just 42 days.

But nearly 10 years on from his world record,

it's been broken by other riders and now stands at 123 days.

Challenge accepted!

When it actually comes to the world, that 18,000 mile journey,

I guess my greatest concern is leg one, going from Paris

through to Beijing through places like Russia, Mongolia, China.

There is a lot which is outwith our control as a team.

But Mark doesn't want to just beat the existing record

by a couple of days, he wants to do it in 80 days.

It's an 18,000 mile journey, which means he'll have to bike more

than 200 miles each day to set the record.

And as a warm up he's going on a seaside trip around Britain,

biking around the coastline to test his endurance.

I need a journey like this to get myself into shape

so my support team know exactly what they are doing

in preparation for the world.

We are going to be trying to hold what will be sub 80 days,

about 240 miles a day.

I am also quite excited to do a big adventure on home soil.

If it all goes well on his warm up round Britain, Mark is planning

to start his round the world record attempt in July.

From one record-breaker to another.

A rare pink diamond has become the most expensive gemstone

ever sold in an auction.

The 60-carat "Pink Star" is the largest of its kind ever found.

It was bought for more than ?57 million in Hong Kong

by a jeweller called Chow Tai Fook.

And something else small to finish.

Have a look at these amazing miniature cites from around

the world that have been built in New York City in America.

Artists have spent ages making models of cites like Paris in France

and Moscow in Russia.

There are even British landmarks such as Tower Bridge or even

Buckingham Palace in London with the flags flying.

That's all from me.

Newsround's back on CBBC this afternoon at 4:20pm with Leah.

Have a brilliant day at school.
