:00:17. > :00:19.I am taking a look at all the latest technology here in Las Vegas
:00:20. > :00:23.and I will be finding out how this alarm clock wakes you up
:00:24. > :00:34.First to Australia where a massive bushfire has destroyed more
:00:35. > :00:41.It's one of the worst fires of the Australian summer so far
:00:42. > :00:48.The fire has been fuelled by winds, which has meant around 500 square
:00:49. > :00:54.Firefighters have been working 24 hours a day to try to bring
:00:55. > :01:00.Secret agents in America have arrested someone who planned
:01:01. > :01:07.Bo and Sunny are Portuguese water dogs.
:01:08. > :01:10.They were a present to Sasha and Malia, President Obama's

:01:17. > :01:19.This week, Ricky's been in Las Vegas, America,
:01:20. > :01:22.at the biggest gadget show in the world.
:01:23. > :01:33.Here's his round-up of some of the weirdest tech that he's seen.
:01:34. > :01:38.So, this sofa has been specially adapted to move to coincide
:01:39. > :01:42.with the movement of the video game. Oh!
:01:43. > :01:45.So it has got special pads underneath each leg and they got up
:01:46. > :01:53.and down depending on what you are doing in the actual game.
:01:54. > :01:56.19-year-old Guillaume designed this alarm clock that wakes you up
:01:57. > :02:02.He came up with the idea and created this very first model
:02:03. > :02:07.Each cartridge has a different scent.
:02:08. > :02:11.When it is time for your alarm to go off, the fan inside pushes the smell
:02:12. > :02:19.This one smells like a coffee chocolate.
:02:20. > :02:22.That's smells like the sea, like holiday smell.
:02:23. > :02:26.That's what I would like to wake up to.
:02:27. > :02:29.Now if you are like me and you are someone who loses your
:02:30. > :02:32.umbrella all the time then this could be for you.
:02:33. > :02:35.Inside this umbrella, there is a chip which connects
:02:36. > :02:38.to your phone and it can tell if you're walking away
:02:39. > :02:41.from your umbrella so it sends you an alert to tell you,
:02:42. > :02:48.And if you are not a fan of doing the housework, then this
:02:49. > :02:50.could be your thing, a robot that does all the hoovering.
:02:51. > :02:54.We have also got robots to clean windows too.
:02:55. > :02:58.This robot is meant to help patients in hospitals to relax.
:02:59. > :03:01.If you cannot get a real pet into a hospital, then you can use
:03:02. > :03:06.this robot and it responds to you whenever you stroke
:03:07. > :03:10.it - it moves around. It is a bit like having a real pet.
:03:11. > :03:13.So there you have it, all the weirdest tech
:03:14. > :03:17.from the biggest gadget show in the world.
:03:18. > :03:20.Head over to the Newsround website to see Ricky testing out a brand
:03:21. > :03:27.If, like me, you love to dance then keep watching,
:03:28. > :03:38.according to scientists, dinosaurs liked to bust a move too -
:03:39. > :03:41.so I've been looking in to what gets a dino's body moving.
:03:42. > :03:43.Have you ever try to impress anyone with your dance moves?
:03:44. > :03:46.Well, you might have something in common with dinosaurs.
:03:47. > :03:50.Scientists who study them say they used to perform a special bird
:03:51. > :03:55.Huge scrapes have been found in rocks left by the animals
:03:56. > :04:00.The patterns are similar to those left by puffins and ostriches
:04:01. > :04:02.after they do their special mating dances.
:04:03. > :04:05.The kind of dinosaurs that left these marks are still unknown
:04:06. > :04:08.but the findings have brought scientists one step closer
:04:09. > :04:19.That is the grooviest dinosaur I have ever seen!
:04:20. > :04:21.To football now and Liverpool could only manage a draw
:04:22. > :04:25.against League Two side Exeter in the third round of the FA Cup.
:04:26. > :04:28.Brad Smith scored the Reds' second goal which means the two sides
:04:29. > :04:32.Liverpool manager Jurgen Klopp fielded an inexperienced team
:04:33. > :04:35.with three players making their debut.
:04:36. > :04:39.Exeter manager Paul Tisdale is looking forward to the replay.
:04:40. > :04:43.We have put on a really good show, it is a pity we could not have
:04:44. > :04:45.played on a good surface because we had to play
:04:46. > :04:47.the conditions today and it was very, very difficult
:04:48. > :04:51.but we will get a chance to play on a plumb surface now at Anfield
:04:52. > :04:55.Justin Bieber has made chart history by sitting at numbers one,
:04:56. > :04:59.two and three in the UK singles chart!

:05:06. > :05:11.How many elephants can you feed with a Christmas tree?
:05:12. > :05:17.These three elephants in the Viennese Zoo were given
:05:18. > :05:20.a healthy snack to get them through the cold winter months.
:05:21. > :05:23.And their snack came from one of the tallest Christmas trees.
:05:24. > :05:26.An 18-meter-tall and 90-year-old spruce tree.
:05:27. > :05:29.A pretty big feast for anyone but for these elephants,
:05:30. > :05:35.including two-year-old Iqua, it was a nutritious treat.
:05:36. > :05:39.And before we go take a look at this dog, who just loves watching
:05:40. > :05:42.the darts so much he wants to get involved and tries
:05:43. > :05:48.And he's coming back now to try again!
