Leah here, live with news about an amazing science prize and a big bear

First, we're talking about a global competition to solve

one of the great scientific problems facing our world.

?10 million is on offer for the winner the Longitude Prize.

There are six big questions and tonight

a massive UK-wide vote launches to decide which one entrants will have

Joining me in the studio to talk Mora bought this is scientist Fran

Scott. Thank you for joining us. Let's talk about the price. It's

incredible, and it's based on a prize that was launched 300 years

ago, in 1714. At that time challenge was to come up with an accurate way

to pinpoint where a ship was at sea. What was brilliant about the prize

was that it wasn't just opened up to the top scientists, it was opened up

to everyone. Anybody could come up with a solution. In fact the winner

was not a scientist at all, he was a clockmaker from Yorkshire called

John Harrison. I am loving that. The brilliant thing is that children can

also get involved. Children can completely get involved. We want

them to get involved. The first way is to vote for the challenge to be

covered. We saw the six options there, and the way they can voters

that they need to go on the website for the BBC programme Horizon.

Voting opens at ten o'clock tonight. There will also be packs sent out to

their schools so they can start a campaign for people to vote for the

campaign they want to win. Thanks for joining us in the studio, and

I'm sure we will hear more in the coming months.

Next, to the technology helping some of the thousands of deaf children

Aysha's been to find out more by meeting schoolgirl Sula,

who's preparing to have the special ear implants fitted.

Sula is like any other in 11-year-old. She enjoys reading,

drawing and listening to music. What are some of your favourite songs? No

way, that's one of my favourites. Sula has been deaf since she was a

baby but has been able to listen to sounds using hearing aids. Recently

though, her hearing has started to get worse, so with her parents she

decided to get something called Cochlear implants. If you have a

hearing problem, one part of the year that might not work as the

Cochlear. An implant is a small device placed under the skin above

the ear. They had pieces worn on the outside and works like a microphone

to pick up sounds which are turned into electrical signals. These are

sent to the implants. From there, they go into the inner ear and up to

the brain. Not everybody in the deaf community thinks Cochlear implants

are a good idea. Something like a hearing aid or a Cochlear implant

takeaway their identity as a deaf person. Our role is to provide

information so people make an informed choice about whether a

Cochlear implant is the option to them. Sula has had to wait five

weeks after the operation before her implants can be switched on. What

are you most looking forward to? Bringing Sula back into a world

where she can gossip and laugh with her friends. That's what we're

looking forward to the most. And you can see Sula have her

implants turned on for the very Before then head to

the website to listen to what it sounds like hearing with a cochlear

implant and find out loads more. And finally if you've ever been told

not to cross the road on your own, This bear cub

in Canada tried to make a break for it on a busy highway but was

hauled back to safety by its mum. Newsround's back

at 6.50pm with loads more.
