0:00:09 > 0:00:12Good morning.
0:00:12 > 0:00:17Ayshah here with your Monday's Newsround.
0:00:17 > 0:00:20But first, Paralympics GB had a spectacular Sunday winning eight
0:00:20 > 0:00:21golds on day four of the games.
0:00:21 > 0:00:24That's Jo Butterfield on the top of the podium there.
0:00:24 > 0:00:28She broke her own world record to win the F51 club throw.
0:00:28 > 0:00:30Other highlights were swimmer Bethany Firth winning the S14
0:00:30 > 0:00:33200 metres freestyle.
0:00:33 > 0:00:36And on the track Richard Whitehead defended his T42 200 metres title.
0:00:36 > 0:00:38The British team are second in the medal table,
0:00:38 > 0:00:43with a whopping 23 golds.
0:00:43 > 0:00:46Next, families in Cumbria in north-west England have been
0:00:46 > 0:00:50moving back into their homes after floods last December
0:00:50 > 0:00:52left thousands of people without anywhere to live.
0:00:52 > 0:00:54Christmas wasn't the only thing ruined.
0:00:54 > 0:00:57Many homes had to be repaired, costing billions of pounds.
0:00:57 > 0:01:00Well, Leah's been to meet one family in the town of Kendal
0:01:00 > 0:01:10who are finally making a fresh start after a difficult few months.
0:01:10 > 0:01:15Zoe, Ali, These are some of the pictures you took
0:01:15 > 0:01:16during the floods.
0:01:16 > 0:01:17Can you talk me through them?
0:01:17 > 0:01:18It was disgusting, just horrible.
0:01:18 > 0:01:19Really?
0:01:19 > 0:01:20I couldn't believe it.
0:01:20 > 0:01:22I was like, what has happened?
0:01:22 > 0:01:25December 2015.
0:01:25 > 0:01:29A time of year Ali and her mum would rather forget.
0:01:29 > 0:01:36It was horrible seeing that in the back garden.
0:01:36 > 0:01:39Heavy rain left thousands of people's homes flooded.
0:01:39 > 0:01:41Roads across parts of the north-west of England and the Borders
0:01:41 > 0:01:47turned into canals.
0:01:47 > 0:01:50Here in Kendal in Cumbria, people's lives were turned upside down.
0:01:50 > 0:01:52Last December was the wettest month on record in the UK.
0:01:52 > 0:01:56And today, things look very different.
0:01:56 > 0:02:01Almost nine months have passed, and now Ali and her mum Zoe
0:02:01 > 0:02:04are moving back into the family home and their life now can
0:02:04 > 0:02:07return back to normal.
0:02:07 > 0:02:10We are back in now and it's all over.
0:02:10 > 0:02:14We don't have to be in a different house, we are all together.
0:02:14 > 0:02:21It's lovely to feel like we're back in.
0:02:21 > 0:02:23Where did the water come to in this room?
0:02:23 > 0:02:24To the top of the fire.
0:02:24 > 0:02:30So, knee-length really.
0:02:30 > 0:02:33I was in my wellies and it was over the top of my knees.
0:02:33 > 0:02:34It was horrible.
0:02:34 > 0:02:36The carpet was black and horrible.
0:02:36 > 0:02:37I was like, this isn't happening.
0:02:37 > 0:02:40While the Government is investing billions of pounds into building
0:02:40 > 0:02:48flood defences across the UK, it could take years for families
0:02:48 > 0:02:50like this one to complete the repairs of their homes.
0:02:50 > 0:02:52It feels nice to know that I am here.
0:02:52 > 0:02:54I can come downstairs and sit on the sofa.
0:02:54 > 0:02:57There's all the people that have helped and been really kind
0:02:57 > 0:02:59towards people, and it is really nice to be here.
0:02:59 > 0:03:00Onwards and upwards.
0:03:00 > 0:03:02Ali will never forget what happened to her
0:03:02 > 0:03:04and so many of her neighbours.
0:03:04 > 0:03:12But now, finally, this is a chance for a new start in home.
0:03:12 > 0:03:14Have a look at these giraffes.
0:03:14 > 0:03:16They look pretty similar, right?
0:03:16 > 0:03:20Well, actually, they're all different species.
0:03:20 > 0:03:23Scientists in Namibia in Africa have found out that there are four
0:03:23 > 0:03:24species of giraffe, not just one.
0:03:24 > 0:03:28The BBC's science reporter Victoria Gill has more.
0:03:28 > 0:03:31They are Africa's gentlest giants.
0:03:31 > 0:03:33But these animals are in decline as their natural
0:03:33 > 0:03:38habitat is shrinking.
0:03:38 > 0:03:41That threat was the trigger for scientists to sample giraffe DNA
0:03:41 > 0:03:45to find out more about these increasingly fragmented populations.
0:03:45 > 0:03:49This revealed a genetic surprise.
0:03:49 > 0:03:52What these new results show is that there are actually
0:03:52 > 0:03:54four different species of giraffe, all very tall
0:03:54 > 0:03:56and they look very similar.
0:03:56 > 0:04:00But they are as genetically distinct from another has a polar bear
0:04:00 > 0:04:04is from a brown bear.
0:04:04 > 0:04:07So, these animals have now been newly categorised.
0:04:07 > 0:04:09There are reticulated giraffes, northern giraffes, the southern
0:04:09 > 0:04:13giraffe and Masai giraffe.
0:04:13 > 0:04:16It may look like a tricky game of spot the difference
0:04:16 > 0:04:23but to conservationists it is crucial information.
0:04:23 > 0:04:24Now understanding these real genetic differences helps us
0:04:24 > 0:04:27understand there may be differences in mating behaviour,
0:04:27 > 0:04:32breeding patterns which are critical to conserving a species.
0:04:32 > 0:04:34The wild population of giraffes has declined by 40%
0:04:34 > 0:04:37in the last 15 years.
0:04:37 > 0:04:40So, looking deep into their DNA could help conservationists
0:04:40 > 0:04:49understand and protect the world's tallest mammals.
0:04:49 > 0:04:51Join us in half-an-hour when we'll have even more
0:04:51 > 0:04:52Paralympic action for you.
0:04:52 > 0:04:53See you soon.
