It's Tuesday morning, Ayshah here with your Newsround headlines.

:00:00.:00:08.

Coming up in the next five: A copycat of one of the world's most

:00:09.:00:11.

spectacular archaeological discoveries.

:00:12.:00:13.

And: What's thinner than paper, stronger

:00:14.:00:16.

than metal and made in a kitchen blender? Stay tuned to find out.

:00:17.:00:24.

But first to our main story. There's been a second night of tornadoes in

:00:25.:00:33.

southern America. As At least 19 people have died. Buildings have

:00:34.:00:36.

been destroyed and cars have been overturned. Emergency services are

:00:37.:00:39.

looking for more survivors. You may recognise this guy from your

:00:40.:00:44.

history lessons. His name is King Tutankhamun and he became ruler of

:00:45.:00:47.

Egypt before he was even ten! His tomb is one of the world's most

:00:48.:00:50.

spectacular archaeological discoveries, but the 3,000-year-old

:00:51.:00:52.

site is crumbling after years and years of visitors. So in a bid to

:00:53.:00:59.

save the remains, an exact copy is being opened nearby, in the hope

:01:00.:01:03.

people will go and see that instead. But will it work? The BBC's Rajan

:01:04.:01:10.

Datar has had a sneak preview of it and he joins us now live. So you

:01:11.:01:16.

have seen both the original and the replica. How bad is the damage to

:01:17.:01:22.

the original? It is pretty bad, to be honest. 90 years of two wrists

:01:23.:01:26.

trooping in and out have caused a lot of damage, the paint his peeling

:01:27.:01:32.

off the walls and that is caused by human breath and particles of human

:01:33.:01:37.

skin, so every day, it gets worse. What is the replica like? How

:01:38.:01:43.

similar is it? An awful lot of work went into making the replica, they

:01:44.:01:46.

used laser scanning, state-of-the-art equipment, and

:01:47.:01:53.

three beeping --3-D printing. When I went down there, I was impressed,

:01:54.:01:58.

and an Egyptologist I was with was impressed, so it is a thumbs up. You

:01:59.:02:03.

think tourists will choose to see the copy instead of the original? I

:02:04.:02:08.

think ultimately, they will have no choice because in the long term,

:02:09.:02:12.

they are hoping to restrict public access to the old tomb. The new tomb

:02:13.:02:20.

has a lot of new features and will be multi-educational. That is the

:02:21.:02:23.

way that, unfortunately, cultural tourism will go, when weaker we will

:02:24.:02:28.

have to be very careful and restricted and the future will be

:02:29.:02:32.

copies. -- when we go. Thank you very much.

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

:02:36.:02:38.

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

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

:02:41.:02:43.

26 minutes, with two more goals scored just before and after half

:02:44.:02:53.

time. Next, it's thinner than paper,

:02:54.:02:56.

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

smartphones. Graphene has fascinated scientists for years, but now

:03:00.:03:03.

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

:03:04.:03:07.

going to want to miss this. Take it away, Martin.

:03:08.:03:15.

Hotter than -- harder than diamonds, 300 times stronger than

:03:16.:03:27.

steel, and the finished material is very useful. Graphene was first made

:03:28.:03:30.

ten years ago here at the University of Manchester when scientists

:03:31.:03:36.

realised the sticky tape was pulling graphene crystals of a lump of

:03:37.:03:41.

graphite. As well as being tough and then, it is see-through, bending and

:03:42.:03:45.

conduct electricity. In the future, it could be used to make superlight

:03:46.:03:50.

planes, then the spot fines and even electronic paper. -- end a

:03:51.:03:56.

smartphones. But the crystals are so small, you need to have many of them

:03:57.:04:06.

to make things. The best way to find them is a search that is on. Now

:04:07.:04:11.

scientists have found putting graphite in a kitchen blender helps.

:04:12.:04:15.

It allows us to make a large amount of graphene in ways that are cheaper

:04:16.:04:19.

than we have had before. The graphene made in a blender is very

:04:20.:04:24.

good for things like printable inks, you can make an ink you can put in a

:04:25.:04:29.

printer, you can make electrical circuits on paper. There are other

:04:30.:04:32.

applications, like computer chips, which you cannot use this graphene

:04:33.:04:38.

four. We won't be seeing it in planes or cars for awhile yet, but

:04:39.:04:41.

smartphones with graphene screens are already in development. Not bad

:04:42.:04:46.

for something discovered almost by accident.

:04:47.:04:52.

That's all from me. Newsround's back right here at 8:15am, where you can

:04:53.:04:56.

find out who will be joining these guys at Radio 1's Big Weekend. See

:04:57.:04:58.

you then.
