See you.

Morning, I'm Ricky, it's Friday and you are live

with Newsround on CBBC.

All this on the way...

How a fly's eyes make it a deadly hunter.

And the new 3D printed hand built at a school.

But first to the Great Barrier Reef, off the coast

of Queensland in Australia.

It's the largest living thing on earth,

and even visible from outer space.

But scientists say it has been hit by widespread bleaching

of its corals for the second year in a row.

The first aerial survey of 2017 shows large areas

of the reef have been damaged by high water temperatures.

Experts say they're worried about the reef's long-term health.

Next up, the scientists getting a fly's-eye view of the world.

This insect has some pretty impressive eyes and researchers have

been finding out how they help them to be so good at hunting.

This tiny robber fly is the size of a grain of rice but can pinpoint

and catch prey in midair.

It locks onto its target in less than a second.

It's all down to the robber fly's eyes.

They have large lenses and a lot of really tiny sensors which allow

them to spot and lock onto their prey.

This means they can really see well.

In fact, the small fly has the same detail of vision

of a much larger dragonfly.

Researchers used high-speed cameras to show how the fly positions itself

to capture moving prey, and found out that the fly

keeps its victim in its line of sight the whole time.

The next step for scientists is to find how the fly's brain takes

this information and turns it into action in the blink of an eye.

Now to the 3D printed hand which has been made at a school.

It's for Andrew - he was born with a condition which means one

of his hands is smaller and less developed than the other.

It will help him grip things more easily.

The hand was made at a school which is the only one in the UK

to have a manufacturing lab.

I do enjoy helping people, and I think this is something that

really would leave a big impact on his life.

It's also good for us because we can learn more about it

and how it's made.

We want to give him the opportunities that he should be

able to do at such a young age.

Football now, and this weekend it's the FA Cup quarterfinals.

And taking on the mighty Arsenal, are non-league Lincoln City,

who made it through thanks to a dramatic last minute winner

who made it through thanks to a dramatic last minute winner

against Premier League team Burnley.

Can they do it again?

Can they do it again?

Can they do it again?

Can they do it again?

We asked some young fans.

ALL: Come on, Lincoln.

Hi, I'm Kieron.

Hi, I'm Josh.

Hi, I'm Charlie.

ALL: We all play for Lincoln Academy.

Welcome to our club.

COMMENTATOR: One last chance for the Lincoln

centre-halves to come forward.

Sam Habergham will sweep this in left-footed.

To the far stick it goes, headed back across goal!

Raggett!

Oh, I thought it was in!

It is in!

And Lincoln City, of non-league football,

of the National League, take the lead at Premier League

Burnley with a minute to go!

Lincoln have made history!

It's the first time ever in our history that we've got

this far in the FA Cup.

People around Lincoln are very excited for

the quarterfinals against Arsenal.

It's really inspired me because Lincoln have just made

everybody try harder and work harder because you know

you can do that well.

If we got through to the semifinals it would be

amazing to go to Wembley.

I think Lincoln could do well.

They'll do well if they scored, and if they won it would be amazing.

I think Arsenal need to watch out for Matt Rhead and Nathan Arnold.

I think Matt Rhead will bully their defence and Nathan Arnold

will be really quick.

I'm a bit worried of what Sanchez and Ozil can do because they're

both great players.

I really want to play for Lincoln when I'm older.

Watching this FA Cup has been amazing, it's really inspired me.

My prediction is 2-1 to Lincoln.

I predict 2-0 Lincoln, Matt Rhead and Luke Waterfall to score.

1-0 Lincoln.

2-1 to Lincoln.

Probably 2-1 Arsenal.

COMMENTATOR: This is the first time in 103 years that the FA Cup has

a non-league side in the last eight!

Good luck, Lincoln.

You can do it.

You can do it in the quarterfinals against Arsenal.

Good luck, Lincoln, I hope you win against Arsenal.

I hope you're going to do amazing.

We can do this!

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