0:00:08 > 0:00:10It's Strictly Saturday and Ore's hot but Brendan's not.
0:00:10 > 0:00:13After dancing celebs, we'll meet these dancing robots.
0:00:13 > 0:00:22And the three heroes helping hedgehogs.
0:00:29 > 0:00:31First up, we're already getting excited for week five
0:00:31 > 0:00:33of Strictly Come Dancing tonight, but professional dancer Brendan Cole
0:00:33 > 0:00:36won't be taking part.
0:00:36 > 0:00:39He's missed training all week as he's been ill.
0:00:39 > 0:00:41His celebrity partner Anastasia has been practising
0:00:41 > 0:00:42with Tameka's ex-professional, Gorka.
0:00:42 > 0:00:44And now he'll step in on the live show too.
0:00:44 > 0:00:48Now, not that we have ANY favourites on this show - but last week's big
0:00:48 > 0:00:50star was Ex-Newsround presenter Ore Oduba who has surprised us
0:00:50 > 0:00:52all with his moves.
0:00:52 > 0:01:00Ore's busy with practice but he managed to send us this.
0:01:00 > 0:01:02Hi, Newsround.
0:01:02 > 0:01:03It's Ore and...
0:01:03 > 0:01:04Jo!
0:01:04 > 0:01:06You might recognise this girl from Saturday night.
0:01:06 > 0:01:07We are rehearsal day.
0:01:07 > 0:01:10Believe it or not, there is a lot of work that
0:01:10 > 0:01:12goes into this show, of course, but you also
0:01:12 > 0:01:17need to rehearse...
0:01:17 > 0:01:18Where to stand.
0:01:18 > 0:01:20Standing and walking down stairs, these stairs behind us, we
0:01:20 > 0:01:22had to practice walking down them.
0:01:22 > 0:01:26Jo and I are dancing waltz this week which is very different to what
0:01:26 > 0:01:28we did last week, the jive.
0:01:28 > 0:01:30And to get, what did we get last week, Jo?
0:01:30 > 0:01:3339.
0:01:33 > 0:01:34We got 39.
0:01:34 > 0:01:37We got 39!
0:01:37 > 0:01:40Biggest score in week four in the history of Strictly.
0:01:40 > 0:01:43Wow.
0:01:43 > 0:01:45Shush, don't tell anyone.
0:01:45 > 0:01:47Which is amazing, we had the best time last week and
0:01:47 > 0:01:49hopefully we'll have another great week but thank
0:01:49 > 0:01:50you for all your support.
0:01:50 > 0:01:52We will see you Saturday night, BBC One,
0:01:52 > 0:01:54hope we'll be back for another week.
0:01:54 > 0:02:02Bye!
0:02:02 > 0:02:04It's been a topsy turvy day three in England's third test
0:02:04 > 0:02:07against Sri Lanka in Bangladesh.
0:02:07 > 0:02:10After taking four wickets for 21 runs this morning,
0:02:10 > 0:02:14England looked to be in a very strong position but Sri Lanka
0:02:14 > 0:02:17hit back taking five wickets in 27 overs.
0:02:17 > 0:02:20England have now steadied the ship somewhat and finished the day on 228
0:02:20 > 0:02:29for eight which gives them a lead of 273 over Bangladesh.
0:02:29 > 0:02:32Now to the last generation of robots being show off in Beijing in China.
0:02:32 > 0:02:35This is the World Robot Conference where all types of robots
0:02:35 > 0:02:42were being shown off - lots of people were interested
0:02:42 > 0:02:44in this bird robot which looks pretty real.
0:02:44 > 0:02:46But the dancing mini robots massively entertained visitors.
0:02:46 > 0:02:48The designer says they could be used in classrooms
0:02:48 > 0:02:52to help children learn.
0:02:52 > 0:02:54And from the brand new, to the really old imagine owning
0:02:54 > 0:03:04a key from the Titanic!
0:03:07 > 0:03:08?30,000.
0:03:08 > 0:03:10It's believed the key was used to open a life
0:03:10 > 0:03:13jacket cupboard to save lives as the ship sank in 1912.
0:03:13 > 0:03:16The key is part of one of the largest sales of Titanic
0:03:16 > 0:03:17items in recent years.
0:03:17 > 0:03:19Now when was the last time you saw a hedgehog?
0:03:19 > 0:03:20Last week?
0:03:20 > 0:03:21Last month?
0:03:21 > 0:03:22EVER?
0:03:22 > 0:03:24Well, research carried out by the Suffolk Wildlife Trust has
0:03:24 > 0:03:27found there has been a huge drop in the number of
0:03:27 > 0:03:28hedgehogs in the UK.
0:03:28 > 0:03:29Martin has been investigating.
0:03:29 > 0:03:30Hedgehogs.
0:03:30 > 0:03:33They're cute and prickly, but life in busy towns and cities
0:03:33 > 0:03:35can present some real dangers for our spiky friends.
0:03:35 > 0:03:37So what's being done to help them?
0:03:37 > 0:03:40Sanctuaries like this one just go to show the problems these little
0:03:40 > 0:03:41guys face in the big wide world.
0:03:41 > 0:03:44Anne has about 80 to 90 hedgehogs here, all tucked up safe and warm.
0:03:44 > 0:03:46They come from various sources.
0:03:46 > 0:03:48They're usually found by people who bring them to us.
0:03:48 > 0:03:49We have abandoned babies.
0:03:49 > 0:03:52Babies that have wandered off on there own and got lost.
0:03:52 > 0:03:54Injuries through strimmers and netting and other road accidents.
0:03:54 > 0:03:57We also have the sick ones that are found lying in people's
0:03:57 > 0:03:58gardens, obviously unwell.
0:03:58 > 0:04:01We try and get them up to weight as soon as possible.
0:04:01 > 0:04:02And then we release them.
0:04:02 > 0:04:0425-year-old Ali is the youngest hedgehog officer in the UK,
0:04:04 > 0:04:07and it's her job to link up these areas of green space,
0:04:07 > 0:04:10to give hedgehogs the chance to move around freely and safely
0:04:10 > 0:04:20when they come out at night to feed.
0:04:24 > 0:04:26We've obviously got lots of great parks across the town.
0:04:26 > 0:04:28But also lots of houses and fences and walls,
0:04:28 > 0:04:31making it difficult for them to get in between these great habitats.
0:04:31 > 0:04:34We are trying to get volunteers on board who will manage
0:04:34 > 0:04:36their gardens for the hedgehogs, and will hopefully persuade
0:04:36 > 0:04:38their neighbours to do the same.
0:04:38 > 0:04:40So we have these whole streets of connected gardens
0:04:40 > 0:04:46that hedgehogs will be able to easily navigate their way through.
0:04:46 > 0:04:49We've got a hole down here so they can get
0:04:49 > 0:04:56through to the other gardens.
0:04:56 > 0:04:58Ten-year-old Daisy is one of the many people from across
0:04:58 > 0:05:01the UK who are doing their bit to help the hedgehogs.
0:05:01 > 0:05:04It's important to take care of hedgehogs because they are
0:05:04 > 0:05:07endangered and I want them to be around when I'm older.
0:05:07 > 0:05:14I've been making it somewhere that's the hedgehogs can come and live in,
0:05:14 > 0:05:19stay and get some food and hibernate.
0:05:19 > 0:05:25For example, I've made some houses, and I give them water and give
0:05:25 > 0:05:28them food and mealworms.
0:05:28 > 0:05:32Anyone my age that wants to do it, I'd say, yes, they can do it
0:05:32 > 0:05:38because the more help that we have, the more hedgehogs there will be.
0:05:38 > 0:05:40And finally scientists in Canada say they've capture rare
0:05:40 > 0:05:42footage of a bowhead whale, one of the country's
0:05:42 > 0:05:44largest marine mammals.
0:05:44 > 0:05:47They used HD drone technology to help get researchers
0:05:47 > 0:05:50closer to the creatures to understand their food and travel
0:05:50 > 0:05:53habits in the Arctic Circle where they live.
0:05:53 > 0:05:56That's all from me, I'll be back tomorrow morning at ten
0:05:56 > 0:05:57with your Sunday Newsround.
0:05:57 > 0:06:00Have a great afternoon!
