0:00:08 > 0:00:10Hello everyone, Hayley here with your last update of the day.
0:00:10 > 0:00:10Coming up.
0:00:10 > 0:00:13Why base jumpers are having to defend their extreme sport.
0:00:13 > 0:00:14And the world's ugliest dog!
0:00:14 > 0:00:22This is Newsround.
0:00:24 > 0:00:26First, before you reach for that cold fizzy drink,
0:00:26 > 0:00:28do you know how much sugar's in it?
0:00:28 > 0:00:31A group of top scientists is worried that too much sugar in food
0:00:31 > 0:00:34and drinks is making kids obese, so now they want to make you pay
0:00:34 > 0:00:35more for the sweet stuff.
0:00:35 > 0:00:38Action on Sugar say that this is one of the biggest problems
0:00:38 > 0:00:40facing kids' health.
0:00:40 > 0:00:44They say that one in five 10 to 11 year olds in the UK is obese,
0:00:44 > 0:00:48while one in three is overweight.
0:00:48 > 0:00:51They want the government to do something about it.
0:00:51 > 0:00:54They think that by making you pay more for the food with sugar in it
0:00:54 > 0:00:56then you're less likely to buy it.
0:00:56 > 0:00:59They also want to ban any junk food sponsorship of sports
0:00:59 > 0:01:03and stop adverts of sugary food being targeted at kids.
0:01:03 > 0:01:06What we're calling on is the soft drink industry
0:01:06 > 0:01:09and Jeremy Hunt in the Department of Health to gradually reduce
0:01:09 > 0:01:12the huge amounts of sugar, like we have done with salt,
0:01:12 > 0:01:16and this will help prevent obesity and type II diabetes
0:01:16 > 0:01:21According to the research done by Action on Sugar, most cans of fizzy
0:01:21 > 0:01:29drinks contain six spoonfuls of sugar and some can contain up to 15.
0:01:29 > 0:01:34They hope by taxing high-sugar food and drinks, that the amount of sugar
0:01:34 > 0:01:40could be halved by 2020.
0:01:40 > 0:01:41The Swiss Alps in Europe are famous for adventure
0:01:41 > 0:01:44sports but there's one in particular which is causing some controversy.
0:01:44 > 0:01:49Base jumping involves leaping with a parachute from high platforms
0:01:49 > 0:01:50on the mountains.
0:01:50 > 0:01:53Some critics argue that it's too dangerous and should be better
0:01:53 > 0:01:56controlled, or even banned.
0:01:56 > 0:01:58Its fans say it's the ultimate experience, and that you should
0:01:58 > 0:02:01always keep safety in mind.
0:02:01 > 0:02:04If you're not thinking about the risk every time you jump,
0:02:04 > 0:02:05you shouldn't be jumping.
0:02:05 > 0:02:07It's something you need to assess every time.
0:02:07 > 0:02:10You know, but also people don't want to die. They don't come here
0:02:10 > 0:02:13thinking, I want to kill myself today, that is not the goal at all.
0:02:13 > 0:02:17We come here to live our lives.
0:02:17 > 0:02:20If you had the chance to solve a big problem in the world,
0:02:20 > 0:02:21what would it be?
0:02:21 > 0:02:24The Longitude prize is a huge science challenge
0:02:24 > 0:02:27and voting is taking place to decide which of the six big world problems
0:02:27 > 0:02:31scientists should tackle for a chance to win ?10million.
0:02:31 > 0:02:36This week we've looked at all six problems, and today it's dementia.
0:02:36 > 0:02:39How can we help people with dementia live independently for longer?
0:02:39 > 0:02:42Here's Ayshah.
0:02:42 > 0:02:44A benefit of modern medicine is that more
0:02:44 > 0:02:46and more of us are living longer.
0:02:46 > 0:02:50But an ageing population brings its own challenges, in particular caring
0:02:50 > 0:02:53for those living with dementia.
0:02:53 > 0:02:55Dementia is a condition that affects the brain.
0:02:55 > 0:02:59Eventually people lose the ability to remember things, they
0:02:59 > 0:03:03get confused, they get irritated and struggle to communicate.
0:03:03 > 0:03:05As the condition gets worse, people can lose
0:03:05 > 0:03:08the ability to do things we all take for granted, like getting dressed
0:03:08 > 0:03:11in the morning or making breakfast.
0:03:11 > 0:03:14It can be difficult not only for the individual but also for
0:03:14 > 0:03:17their families and care network.
0:03:17 > 0:03:20We're a long way off from a treatment or even a cure, but it's
0:03:20 > 0:03:24hoped technology can be a huge help caring for people with dementia.
0:03:24 > 0:03:28Here at Birmingham University, researchers created this robot
0:03:28 > 0:03:32carer, Bob, who can learn where somebody leaves their slippers
0:03:32 > 0:03:37and their keys and uses this information to quickly find things.
0:03:37 > 0:03:39Bob can monitor the positions of people.
0:03:39 > 0:03:42We are looking to detect if people have fallen over, and also
0:03:42 > 0:03:46remind people and notify carers that she's forgotten to take her medicine
0:03:46 > 0:03:49or they haven't got up at the time they should or they are getting up
0:03:49 > 0:03:51at a time they shouldn't.
0:03:51 > 0:03:53With today's technology, what Bob can do is restricted.
0:03:53 > 0:03:57Stairs are a problem, his arms can't do too much and his ability
0:03:57 > 0:04:00to make decisions is limited.
0:04:00 > 0:04:04But it's hoped with robotic advances that a robot carer will one day be
0:04:04 > 0:04:07a reality.
0:04:07 > 0:04:10So if dementia gets chosen for the Longitude prize, the challenge is
0:04:10 > 0:04:14to find a way to help people with dementia live as independently as
0:04:14 > 0:04:18possible for as long as possible.
0:04:18 > 0:04:21Tomorrow sees the start of the Wimbledon championships
0:04:21 > 0:04:25when Andy Murray starts his defence of the men's singles title he won
0:04:25 > 0:04:27so spectacularly last year.
0:04:27 > 0:04:29In tomorrow morning's bulletins Ricky will be live
0:04:29 > 0:04:33at Wimbledon to preview the biggest event in the tennis calendar,
0:04:33 > 0:04:36and we'll bring you all you need to know about the tournament.
0:04:36 > 0:04:41Here's a sneak preview of what you can expect.
0:04:41 > 0:04:43You join us for this epic match.
0:04:43 > 0:04:45It's Ricky against Leah.
0:04:45 > 0:04:47Two players at the top of their game.
0:04:47 > 0:04:50It's Ricky to serve first.
0:04:50 > 0:04:52Nice forehand by Leah. Back from Ricky.
0:04:52 > 0:04:54Leah returns.
0:04:54 > 0:04:56That shot's deep from Ricky.
0:04:56 > 0:04:58Out! And the umpire says it out.
0:04:58 > 0:05:01You cannot be serious?!
0:05:01 > 0:05:02Out!
0:05:02 > 0:05:05For years, players unhappy with the decisions
0:05:05 > 0:05:08made by the umpire have released their frustrations on the court.
0:05:08 > 0:05:11But if they're playing for one of the four courts that use Hawk-eye,
0:05:11 > 0:05:17they can always challenge the line call.
0:05:17 > 0:05:20And finally let me introduce you to Peanut.
0:05:20 > 0:05:22Cute, isn't he?
0:05:22 > 0:05:28Well, not according to judges who've crowned him the World's Ugliest Dog!
0:05:28 > 0:05:31The annual contest in America includes lots of rescue animals
0:05:31 > 0:05:33and aims to raise awareness of animal cruelty.
0:05:33 > 0:05:36Peanut's owner says she'll be donating all the prize
0:05:36 > 0:05:39money to help other animals.
0:05:39 > 0:05:43And for the record, I think Peanut's beautiful!
0:05:43 > 0:05:46And speaking of ugly dogs, a reminder that if you like your
0:05:46 > 0:05:49World Cup commentary a little bit alternative, Wigan's finest Hacker T
0:05:49 > 0:05:53Dog will be doing a very special commentary during the Belgium Russia
0:05:53 > 0:05:54match this afternoon.
0:05:54 > 0:05:57Press your red button from 5 o'clock!
0:05:57 > 0:05:59Newsround's back in the morning, bye!
