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. | :02:33. | :02:35. | |
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 | :02:39. | :02:40. | |
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 | :02:57. | :02:59. | |
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. | :04:59. | :05:00. |
