Hi, I'm Ayshah with your last news update of the day. First to a huge

medical breakthrough that brings hope for people with spinal

injuries. Four paralysed men who had been unable to move from the chest

down can now move their legs, after a new treatment in America. We've

spoken to a brain expert to find out how it works. Down here is this

spinal-cord. This is how the brain can indicate with the body. For

someone who can't move their legs, it is often a spinal-cord injury

that causes it. The doctors put in an electrical stimulating device

which increases the amount of electrical activity there. Only a

very weak single -- signal can cross the damage. I increasing the

electrical activity here, it allows it to carry on down and these guys

can suddenly, in the first week of this stimulation, move their legs

again stop this is specifically for people who have had an injury to

their spinal-cord. It won't help everyone but for people who have had

traumatic spinal injuries, there is a lot of hope.

One of the world's biggest long distance running races, the London

Marathon, takes place this Sunday. And for the first time, Team GB star

Mo Farah will go up against some of the best in the world at this

distance. He'll be running the full 26-mile distance through the London

streets against some pretty tough competitors from Kenya and Ethiopia,

but he's pretty confident. It is completely different. Preparing for

the track to the road. The reason it is different is because it is such a

long way. You don't get it easy. On Sunday my first aim is to go after

the British record and secondly see what else comes along to stop mainly

it is to try and respect the distance. Chelsea boss Jose Mourinho

is confident his side can make a comeback in their Champions League

second leg against Paris St-Germain. The Blues are two goals behind but

the boss reckons they'll score more goals than PSG, who will be without

injured striker Ibrahimovic. At the end of the two legs I think we will

score more goals than them. At this moment it is 3-1. I think in the end

it can be for-3. I think we will win.

Next - if you don't like heights, you might want to look away now.

We'd say don't try this at home but we're guessing none of you live in

mid-air above the River Seine. This is French tightrope walker Dennis

Josselin, in Paris on Sunday. It took him half an hour to cross the

rope which was suspended more than 20 metres above the famous river.

Very cute animal news now, and we finally have a name for a pair of

polar bear cubs who were born at a zoo in Germany last year! The male

cub is called Nobby and his sister is called Nela. All animals born at

the German zoo in 2013 have been given names beginning with "N", and

so these twins are no exception. That's all from me, Newsround's back

tomorrow morning.
