Hello everyone, Hayley here with your last update of the day.

Coming up.

Why base jumpers are having to defend their extreme sport.

And the world's ugliest dog!

This is Newsround.

First, before you reach for that cold fizzy drink,

do you know how much sugar's in it?

A group of top scientists is worried that too much sugar in food

and drinks is making kids obese, so now they want to make you pay

more for the sweet stuff.

Action on Sugar say that this is one of the biggest problems

facing kids' health.

They say that one in five 10 to 11 year olds in the UK is obese,

while one in three is overweight.

They want the government to do something about it.

They think that by making you pay more for the food with sugar in it

then you're less likely to buy it.

They also want to ban any junk food sponsorship of sports

and stop adverts of sugary food being targeted at kids.

What we're calling on is the soft drink industry

and Jeremy Hunt in the Department of Health to gradually reduce

the huge amounts of sugar, like we have done with salt,

and this will help prevent obesity and type II diabetes

According to the research done by Action on Sugar, most cans of fizzy

drinks contain six spoonfuls of sugar and some can contain up to 15.

They hope by taxing high-sugar food and drinks, that the amount of sugar

could be halved by 2020.

The Swiss Alps in Europe are famous for adventure

sports but there's one in particular which is causing some controversy.

Base jumping involves leaping with a parachute from high platforms

on the mountains.

Some critics argue that it's too dangerous and should be better

controlled, or even banned.

Its fans say it's the ultimate experience, and that you should

always keep safety in mind.

If you're not thinking about the risk every time you jump,

you shouldn't be jumping.

It's something you need to assess every time.

You know, but also people don't want to die. They don't come here

thinking, I want to kill myself today, that is not the goal at all.

We come here to live our lives.

If you had the chance to solve a big problem in the world,

what would it be?

The Longitude prize is a huge science challenge

and voting is taking place to decide which of the six big world problems

scientists should tackle for a chance to win ?10million.

This week we've looked at all six problems, and today it's dementia.

How can we help people with dementia live independently for longer?

Here's Ayshah.

A benefit of modern medicine is that more

and more of us are living longer.

But an ageing population brings its own challenges, in particular caring

for those living with dementia.

Dementia is a condition that affects the brain.

Eventually people lose the ability to remember things, they

get confused, they get irritated and struggle to communicate.

As the condition gets worse, people can lose

the ability to do things we all take for granted, like getting dressed

in the morning or making breakfast.

It can be difficult not only for the individual but also for

their families and care network.

We're a long way off from a treatment or even a cure, but it's

hoped technology can be a huge help caring for people with dementia.

Here at Birmingham University, researchers created this robot

carer, Bob, who can learn where somebody leaves their slippers

and their keys and uses this information to quickly find things.

Bob can monitor the positions of people.

We are looking to detect if people have fallen over, and also

remind people and notify carers that she's forgotten to take her medicine

or they haven't got up at the time they should or they are getting up

at a time they shouldn't.

With today's technology, what Bob can do is restricted.

Stairs are a problem, his arms can't do too much and his ability

to make decisions is limited.

But it's hoped with robotic advances that a robot carer will one day be

a reality.

So if dementia gets chosen for the Longitude prize, the challenge is

to find a way to help people with dementia live as independently as

possible for as long as possible.

Tomorrow sees the start of the Wimbledon championships

when Andy Murray starts his defence of the men's singles title he won

so spectacularly last year.

In tomorrow morning's bulletins Ricky will be live

at Wimbledon to preview the biggest event in the tennis calendar,

and we'll bring you all you need to know about the tournament.

Here's a sneak preview of what you can expect.

You join us for this epic match.

It's Ricky against Leah.

Two players at the top of their game.

It's Ricky to serve first.

Nice forehand by Leah. Back from Ricky.

Leah returns.

That shot's deep from Ricky.

Out! And the umpire says it out.

You cannot be serious?!

Out!

For years, players unhappy with the decisions

made by the umpire have released their frustrations on the court.

But if they're playing for one of the four courts that use Hawk-eye,

they can always challenge the line call.

And finally let me introduce you to Peanut.

Cute, isn't he?

Well, not according to judges who've crowned him the World's Ugliest Dog!

The annual contest in America includes lots of rescue animals

and aims to raise awareness of animal cruelty.

Peanut's owner says she'll be donating all the prize

money to help other animals.

And for the record, I think Peanut's beautiful!

And speaking of ugly dogs, a reminder that if you like your

World Cup commentary a little bit alternative, Wigan's finest Hacker T

Dog will be doing a very special commentary during the Belgium Russia

match this afternoon.

Press your red button from 5 o'clock!

Newsround's back in the morning, bye!
