:00:35. > :00:37.Doctor Who coming up. I'm Leah and we've also go this on the way. We're
:00:37. > :00:40.checking out the frankenburger that scientists say could save the
:00:41. > :00:44.environment. You're live with Newsround. OK, let's get straight
:00:44. > :00:49.into the latest in a long line of Doctors - Peter Capaldi was revealed
:00:49. > :00:52.as the new man in the TARDIS live on BBC One last night. He'll take over
:00:52. > :00:55.from Matt Smith during this year's Christmas episode. He said just
:00:55. > :00:58.auditioning for the part was a dream come true and he's relieved he
:00:59. > :01:01.doesn't have to keep the news to himself any longer. It is so
:01:01. > :01:03.wonderful not to keep this secret any longer, but it has been
:01:04. > :01:11.fantastic. For a while I couldn't tell my daughter who was looking on
:01:11. > :01:21.the Internet and seeing people saying so-and-so should be the
:01:21. > :01:23.
:01:23. > :01:26.doctor, and she was upset norm of them were saying me. So much hype,
:01:26. > :01:30.and here to talk us through it, I can reveal the world's biggest Dr
:01:31. > :01:40.Who fan is CBBC's Chris Johnson. Welcome, Chris - you predicted it
:01:41. > :01:41.
:01:41. > :01:46.would be Pete on Friday - why was he the right choice for you? He has won
:01:46. > :01:52.an Oscar for directing and loads of other stuff, he knows his television
:01:52. > :01:58.so I am delighted he has got the part. He is delighted as well. We
:01:58. > :02:07.have been speaking to some kids to find out what they thought. Take a
:02:07. > :02:15.look at this. I was shocked. I was like, who is he? I don't really know
:02:15. > :02:19.who it is. We would have liked it to be a woman. A lot of people on the
:02:19. > :02:28.Newsround website as saying Peter is fantastic choice but there are some
:02:28. > :02:32.concerns. Rosey in Wiltshire says "Nobody will ever be as good as Matt
:02:32. > :02:35.Smith". And Harry in Swansea says "I don't like him because he doesn't
:02:35. > :02:39.look right!" Chris what can you say to these guys? I would say, calm
:02:39. > :02:45.down, don't worry. When David Tennant left everybody was saying
:02:45. > :02:51.who is Matt Smith and later he was everybody's favourite doctor. In
:02:51. > :02:56.terms of the age of the actor, it doesn't matter as long as they bring
:02:56. > :03:06.something new to the part. The doctor can be in his 20s, his 50s,
:03:06. > :03:08.
:03:08. > :03:11.and I think he will just bring something very unique to the part.
:03:11. > :03:15.Well Chris thanks for coming in. Well, it seems lots of Doctorr Who
:03:15. > :03:18.fans are still not entirely sure what to expect from Peter Capaldi,
:03:18. > :03:28.so we've put together five top facts about the newest Time Lord. At
:03:28. > :03:30.
:03:30. > :03:35.school Peter was the singer of a punk rock group. He is a Doctor Who
:03:35. > :03:41.super fan himself, when he was 14 he wrote letters to the makers saying
:03:41. > :03:46.it inspired him to work in TV. You might not have seen him in action
:03:46. > :03:56.before but he has won awards and even an Oscar in the past. He has
:03:56. > :04:03.
:04:03. > :04:05.already been in an episode of Doctor Who... And from the king of time
:04:05. > :04:08.travel to a futuristic frankenburger. The meat was grown in
:04:08. > :04:12.a laboratory and the scientists behind it say the technology could
:04:12. > :04:15.help the environment and prevent cows having to be killed in the
:04:15. > :04:17.future. It was revealed at a secret location today and Ricky was right
:04:17. > :04:20.there. Today scientists revealed and cooked the world's first laboratory
:04:20. > :04:25.grown burger and the meat was made using special cells from a living
:04:25. > :04:32.count, they then turned them into tiny muscles in the science lab and
:04:32. > :04:39.mixed them with a chemical to help them grow. There is an intense
:04:39. > :04:45.taste, it is close to meet, not that juicy. They say it is a more
:04:45. > :04:50.environmentally friendly way of making meat. Making meat has always
