Happy Tuesday morning. I'm Ayshah with your morning Newsround.

Arsenal tighten their grip on the race for fourth place.

And what's thinner than paper, stronger than metal and made in a

kitchen blender? Stay tuned to find out.

You may recognise this guy from your history lessons. His name is King

Tutankhamun and he became ruler of Egypt before he was even ten! But

the 3000-year-old site is crumbling after years and years of visitors.

So officials have come up with an unusual plan to protect it.

The Valley of the Kings. The final resting place for the pharaohs of

Egypt's. The most famous tomb is that of Tutankhamun. Discovered in

1922 by British archaeologist Howard Carter, it stunned the world,

because it was in almost perfect condition. But after 92 years, the

number of people visiting the tomb is causing it's a delicate walls to

fall apart. Since Carter opened the tomb up, the constant changes of

humidity. The changes and moisture levels. The airborne pollutants that

come in with people. Those have an effect on the tomb. Now there is a

plan to save the tomb. An exact copy of it has been built a few

kilometres away. It was created by a special team using laser scanners

and 3D printers. It is hoped that tourists will go and see the copy

instead of the crumbling original. But will visitors want to see a

fake? A BBC team were given a sneak preview of it. They took an expert

on Egypt to see what he thought. Well, I'm sorry. But I have to say,

it's marvellous. ?? WHITE LAUGHTER. Making a copy of a historical

attraction might sound strange. But it isn't the first time it's

happened. The prehistoric paintings inside France's Lasko Caves were

copied after the original caves shut in the 1960s. Tourists see the copy

rather than the original. The real Tutankhamun tomb may eventually have

to close, so that it can be preserved. But for now, visitors

will have a choice between it and its copy.

Sport now and Arsenal are set to secure their 17th Champions' League

appearance next season after beating Newcastle United 3-0 at home last

night. Gunner's defender Laurent Koscielny opened the scoring after

26 minutes. Two more goals were scored just before and after half

time. Next, it's thinner than paper,

stronger than metal and could one day be used to make bendy

smartphones. Graphene has fascinated scientists for years. But now,

they've found a new way to make it. In a kitchen blender! You're not

going to want to miss this. Harder than diamonds. 300 times

stronger than steel. And the thinnest material ever discovered.

All these things make graphene. A very useful material. Graphene was

first made ten years ago here at the University of Manchester. Scientists

realised their sticky tape was pulling graphene crystals off a lump

of graphite. As well as being strong, tough and thin, graphene is

see-through, bendy and conducts electricity. In the future, it could

be used to make superlight planes, bendy smartphones. Even electronic

paper. But graphene crystals are so small, you need a lot of them to

make things. So the search is on to find the best way to make them. Now

a group of scientists in Ireland have found they can extract thin

layers of graphene crystals by putting graphite in a kitchen

blender. It allows us to make a large amount of graphene.

Potentially in a way that's a lot cheaper than other ways we've had

before. The graphene you make with a blender is very good for things like

printable inks, for example. You can make ink that you can put in a

printer and make electrically conducting circuits on paper. There

are some other applications. Electronics, like computer chips,

for example, which you can't use this graphene for. We won't be using

graphene in planes or cars for a few years yet, but smartphones with

graphene screens are already in development. Not bad for something

discovered almost by accident. And finally, Katy Perry has been

confirmed as the latest act to perform at Radio Ones Big Weekend in

Glasgow next month. She'll join the One Direction boys, who are

currently in Peru on the latest leg of their World Tour. Other artists

confirmed for the Big Weekend include Ed Shearan and The Vamps.

Over 50,000 tickets have been given away to excited fans and it's the

largest free event in Europe. That's all from me. Newsround's back

with Ricky in the afternoon. See you later.
