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

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

The new 3D printed hand built at a school.

And the elephant getting shiny new tusks.

First up, football - and this weekend it's

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

who made it through thanks to a dramatic last-minute winner

ALL: We all play for Lincoln Academy.

COMMENTATOR: One last chance for the Lincoln

Sam Habergham will sweep this in left-footed.

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

And Lincoln City, of non-league football,

of the National League, take the lead at Premier League

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

People around Lincoln are really excited for

It's really inspired me because Lincoln have just made

everybody try harder and work harder because you know

If we got through to the semifinals it would be

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

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

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

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

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

You can do it in the quarterfinals against Arsenal.

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

Next to the Great Barrier Reef, off the coast

It's the largest living thing on earth, and even

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.

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

It's for 5-year-old Andrew - he was born

with a condition which means one of his hands is smaller and less

It will help him grip things more easily.

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

Andrew 's parents said handle make a real difference to him. He does

adapt quite well and cope quite well as it is. It's little things that

will just improve him, like holding a bottle, using his hand puddings,

it will benefit him, it? Yes. 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 We want to give him

the opportunities that he should be 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 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. In fact, the small fly has

the same detail of vision 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. Next, this is the world's rarest

stamp and it's worth The one-cent Magenta stamp

was printed in the south American country of Guyana

more than 150 years ago. The world's most valuable stamp

will now go on display at the National Postal Museum

in the United States. Last up, meet this

13-year-old elephant. He lives in a zoo in

California in the US. He's just been fitted with these

special shiny brass caps to cover The elephant's tusks were cracked

so these new caps will hopefully That's all from me, Newsround's back
