:00:07. > :00:12.Hi, I'm Ayshah with your last news update of the day. First to a huge
:00:13. > :00:15.medical breakthrough that brings hope for people with spinal
:00:16. > :00:19.injuries. Four paralysed men who had been unable to move from the chest
:00:20. > :00:23.down can now move their legs, after a new treatment in America. We've
:00:24. > :00:31.spoken to a brain expert to find out how it works. Down here is this
:00:32. > :00:37.spinal-cord. This is how the brain can indicate with the body. For
:00:38. > :00:41.someone who can't move their legs, it is often a spinal-cord injury
:00:42. > :00:50.that causes it. The doctors put in an electrical stimulating device
:00:51. > :01:01.which increases the amount of electrical activity there. Only a
:01:02. > :01:07.very weak single -- signal can cross the damage. I increasing the
:01:08. > :01:12.electrical activity here, it allows it to carry on down and these guys
:01:13. > :01:18.can suddenly, in the first week of this stimulation, move their legs
:01:19. > :01:24.again stop this is specifically for people who have had an injury to
:01:25. > :01:32.their spinal-cord. It won't help everyone but for people who have had
:01:33. > :01:36.traumatic spinal injuries, there is a lot of hope.
:01:37. > :01:39.One of the world's biggest long distance running races, the London
:01:40. > :01:43.Marathon, takes place this Sunday. And for the first time, Team GB star
:01:44. > :01:47.Mo Farah will go up against some of the best in the world at this
:01:48. > :01:50.distance. He'll be running the full 26-mile distance through the London
:01:51. > :01:58.streets against some pretty tough competitors from Kenya and Ethiopia,
:01:59. > :02:06.but he's pretty confident. It is completely different. Preparing for
:02:07. > :02:15.the track to the road. The reason it is different is because it is such a
:02:16. > :02:20.long way. You don't get it easy. On Sunday my first aim is to go after
:02:21. > :02:25.the British record and secondly see what else comes along to stop mainly
:02:26. > :02:42.it is to try and respect the distance. Chelsea boss Jose Mourinho
:02:43. > :02:44.is confident his side can make a comeback in their Champions League
:02:45. > :02:48.second leg against Paris St-Germain. The Blues are two goals behind but
:02:49. > :02:51.the boss reckons they'll score more goals than PSG, who will be without
:02:52. > :02:55.injured striker Ibrahimovic. At the end of the two legs I think we will
:02:56. > :03:01.score more goals than them. At this moment it is 3-1. I think in the end
:03:02. > :03:06.it can be for-3. I think we will win.
:03:07. > :03:10.Next - if you don't like heights, you might want to look away now.
:03:11. > :03:14.We'd say don't try this at home but we're guessing none of you live in
:03:15. > :03:17.mid-air above the River Seine. This is French tightrope walker Dennis
:03:18. > :03:21.Josselin, in Paris on Sunday. It took him half an hour to cross the
:03:22. > :03:25.rope which was suspended more than 20 metres above the famous river.
:03:26. > :03:30.Very cute animal news now, and we finally have a name for a pair of
:03:31. > :03:34.polar bear cubs who were born at a zoo in Germany last year! The male
:03:35. > :03:37.cub is called Nobby and his sister is called Nela. All animals born at
:03:38. > :03:42.the German zoo in 2013 have been given names beginning with "N", and
:03:43. > :03:44.so these twins are no exception. That's all from me, Newsround's back
