:00:00. > :00:00.Leah here, live with news about an amazing science prize and a big bear
:00:07. > :00:16.First, we're talking about a global competition to solve
:00:17. > :00:25.one of the great scientific problems facing our world.
:00:26. > :00:27.?10 million is on offer for the winner the Longitude Prize.
:00:28. > :00:29.There are six big questions and tonight
:00:30. > :00:33.a massive UK-wide vote launches to decide which one entrants will have
:00:34. > :01:18.Joining me in the studio to talk Mora bought this is scientist Fran
:01:19. > :01:23.Scott. Thank you for joining us. Let's talk about the price. It's
:01:24. > :01:29.incredible, and it's based on a prize that was launched 300 years
:01:30. > :01:34.ago, in 1714. At that time challenge was to come up with an accurate way
:01:35. > :01:38.to pinpoint where a ship was at sea. What was brilliant about the prize
:01:39. > :01:41.was that it wasn't just opened up to the top scientists, it was opened up
:01:42. > :01:46.to everyone. Anybody could come up with a solution. In fact the winner
:01:47. > :01:52.was not a scientist at all, he was a clockmaker from Yorkshire called
:01:53. > :01:57.John Harrison. I am loving that. The brilliant thing is that children can
:01:58. > :02:00.also get involved. Children can completely get involved. We want
:02:01. > :02:04.them to get involved. The first way is to vote for the challenge to be
:02:05. > :02:08.covered. We saw the six options there, and the way they can voters
:02:09. > :02:17.that they need to go on the website for the BBC programme Horizon.
:02:18. > :02:24.Voting opens at ten o'clock tonight. There will also be packs sent out to
:02:25. > :02:28.their schools so they can start a campaign for people to vote for the
:02:29. > :02:32.campaign they want to win. Thanks for joining us in the studio, and
:02:33. > :02:34.I'm sure we will hear more in the coming months.
:02:35. > :02:37.Next, to the technology helping some of the thousands of deaf children
:02:38. > :02:41.Aysha's been to find out more by meeting schoolgirl Sula,
:02:42. > :02:46.who's preparing to have the special ear implants fitted.
:02:47. > :02:51.Sula is like any other in 11-year-old. She enjoys reading,
:02:52. > :02:59.drawing and listening to music. What are some of your favourite songs? No
:03:00. > :03:03.way, that's one of my favourites. Sula has been deaf since she was a
:03:04. > :03:07.baby but has been able to listen to sounds using hearing aids. Recently
:03:08. > :03:11.though, her hearing has started to get worse, so with her parents she
:03:12. > :03:17.decided to get something called Cochlear implants. If you have a
:03:18. > :03:21.hearing problem, one part of the year that might not work as the
:03:22. > :03:27.Cochlear. An implant is a small device placed under the skin above
:03:28. > :03:32.the ear. They had pieces worn on the outside and works like a microphone
:03:33. > :03:35.to pick up sounds which are turned into electrical signals. These are
:03:36. > :03:40.sent to the implants. From there, they go into the inner ear and up to
:03:41. > :03:44.the brain. Not everybody in the deaf community thinks Cochlear implants
:03:45. > :03:49.are a good idea. Something like a hearing aid or a Cochlear implant
:03:50. > :03:54.takeaway their identity as a deaf person. Our role is to provide
:03:55. > :03:56.information so people make an informed choice about whether a
:03:57. > :04:02.Cochlear implant is the option to them. Sula has had to wait five
:04:03. > :04:04.weeks after the operation before her implants can be switched on. What
:04:05. > :04:20.are you most looking forward to? Bringing Sula back into a world
:04:21. > :04:21.where she can gossip and laugh with her friends. That's what we're
:04:22. > :04:24.looking forward to the most. And you can see Sula have her
:04:25. > :04:28.implants turned on for the very Before then head to
:04:29. > :04:32.the website to listen to what it sounds like hearing with a cochlear
:04:33. > :04:36.implant and find out loads more. And finally if you've ever been told
:04:37. > :04:40.not to cross the road on your own, This bear cub
:04:41. > :04:44.in Canada tried to make a break for it on a busy highway but was
:04:45. > :04:48.hauled back to safety by its mum. Newsround's back
:04:49. > :04:54.at 6.50pm with loads more.
