0:00:16 > 0:00:17Good
0:00:17 > 0:00:17Good morning,
0:00:17 > 0:00:20Good morning, all.
0:00:20 > 0:00:22Flooding in the US city of Houston in America
0:00:22 > 0:00:24is expected to get worse today, after more rain was
0:00:24 > 0:00:25predicted for the area.
0:00:25 > 0:00:27Thousands of people have been rescued from their homes
0:00:27 > 0:00:30after Tropical Storm Harvey battered the city, and many more
0:00:30 > 0:00:32are still waiting for help.
0:00:32 > 0:00:42Later today, President Trump will visit Houston to see the damage.
0:00:42 > 0:00:44Newsround has spoken to Emilio, who lives there.
0:00:44 > 0:00:46He sent us this.
0:00:46 > 0:00:49My school is out for a week and a half because of weather like this.
0:00:49 > 0:00:52We're going to be having to take in some of our friends that
0:00:52 > 0:00:54are getting some bad flooding.
0:00:54 > 0:00:56I know friends that the water's up to their driveway,
0:00:56 > 0:00:58and one of our friends is about to get flooding
0:00:58 > 0:01:01in their house pretty soon, so it's kind of a scary experience,
0:01:01 > 0:01:05but hoping we can get through this.
0:01:06 > 0:01:09Showbiz now, and Strictly fans, this one's for you.
0:01:09 > 0:01:12All the celebs have been revealed, and it's time for them
0:01:12 > 0:01:14to take to the dance floor for the first time.
0:01:14 > 0:01:16Ayshah went to see them strut their stuff.
0:01:16 > 0:01:18That's right.
0:01:18 > 0:01:20It's that time of year when the glitterball is dusted off.
0:01:20 > 0:01:22And...
0:01:22 > 0:01:25We're here on the Strictly red carpet.
0:01:25 > 0:01:27Now, that's showbiz!
0:01:27 > 0:01:28Thanks, Anton!
0:01:28 > 0:01:32And it's safe to say that this year's group of Strictly stars can't
0:01:32 > 0:01:35wait to get started.
0:01:35 > 0:01:37It's going to be huge, because people who've
0:01:37 > 0:01:40watched me on Top Class or The Dog Ate My Homework
0:01:40 > 0:01:42are used to seeing me in a very different way.
0:01:42 > 0:01:47You've never seen me look like this.
0:01:47 > 0:01:48Oh, man.
0:01:48 > 0:01:50It still doesn't feel real.
0:01:50 > 0:01:51But I can tell you it's happening.
0:01:51 > 0:01:52It is happening, right?
0:01:52 > 0:01:53Yeah!
0:01:53 > 0:01:55We are actually going to do the show.
0:01:55 > 0:01:57This year.
0:01:57 > 0:01:58You are going to be dancing.
0:01:58 > 0:02:00In front of loads of people.
0:02:00 > 0:02:01In these shoes.
0:02:01 > 0:02:02Yes.
0:02:02 > 0:02:03Which are already telling me.
0:02:03 > 0:02:04The sequins, the glamour.
0:02:04 > 0:02:07It started already, and we have been getting ready since about ten
0:02:07 > 0:02:08o'clock this morning.
0:02:08 > 0:02:14We are all in our sparkly outfit, even the boys.
0:02:14 > 0:02:16I like the sequins.
0:02:16 > 0:02:17Thank you very much.
0:02:17 > 0:02:23So do I.
0:02:23 > 0:02:26I have sequin envy because Jonnie Peacock has got multicoloured
0:02:26 > 0:02:27sequins and mine are only blue.
0:02:27 > 0:02:30This is not something that I would never normally do.
0:02:30 > 0:02:32But I think that's really good for me to challenge myself.
0:02:32 > 0:02:33Just look at them go!
0:02:33 > 0:02:36But despite the excitement, everyone seems to be a little
0:02:36 > 0:02:37bit nervous about...
0:02:37 > 0:02:38Dancing.
0:02:38 > 0:02:39Obviously, I'm a runner.
0:02:39 > 0:02:40I'm not a dancer.
0:02:40 > 0:02:43Do you know what I'm really nervouc about is doing a dance
0:02:43 > 0:02:44and forgetting the moves.
0:02:44 > 0:02:45I have no background in dancing.
0:02:45 > 0:02:47I can't even dance the YMCA.
0:02:47 > 0:02:49I'm quite nervous about the possibility of forgetting
0:02:49 > 0:02:53everyone I've learned.
0:02:53 > 0:02:54Everyone knows YMCA!
0:02:54 > 0:02:55I know, but I'm not...
0:02:55 > 0:02:57Oh, yeah.
0:02:57 > 0:02:58And falling.
0:02:58 > 0:03:00I don't want to just go flat on my face.
0:03:00 > 0:03:02I want to be able to look graceful.
0:03:02 > 0:03:06Running upstairs in heels, and the fact that the camera is on you...
0:03:06 > 0:03:10I've been told to simply do this.
0:03:10 > 0:03:11And smile!
0:03:11 > 0:03:17So if you see me doing that, some things gone wrong.
0:03:17 > 0:03:21That's it for the red carpet, but it won't be long till we find
0:03:21 > 0:03:23out who the celebs' partners are, and then those Twinkletoes
0:03:23 > 0:03:24will really get going.
0:03:24 > 0:03:27All: Bye, Newsround!
0:03:30 > 0:03:30Nice
0:03:30 > 0:03:31Nice one,
0:03:31 > 0:03:31Nice one, thank
0:03:31 > 0:03:32Nice one, thank you.
0:03:32 > 0:03:35This month marks ten years since hashtags have been
0:03:35 > 0:03:36used on social networks.
0:03:36 > 0:03:39But have you ever wondered were they came from and why we use them?
0:03:39 > 0:03:40Here's Whitney to explain.
0:03:40 > 0:03:42Hashtags are all around us.
0:03:42 > 0:03:44They're used not just online but in everyday life.
0:03:44 > 0:03:52But this wasn't always the case.
0:03:52 > 0:03:54Did you know the hashtag symbol first popped up in the '70s
0:03:54 > 0:04:00and was used by computer experts as a way to make notes in coding.
0:04:00 > 0:04:03And by the '90s, the symbol was used by the Internet relay chat.
0:04:03 > 0:04:05That's an old messaging apps that use that text
0:04:05 > 0:04:07to sort items into groups.
0:04:07 > 0:04:112007 was the birth of the hashtag as we know it.
0:04:11 > 0:04:14That was the very first time hashtags were used on Twitter
0:04:14 > 0:04:17to organise to eat into subjects.
0:04:17 > 0:04:20And this became the normal way that people tweeted.
0:04:20 > 0:04:21And it didn't stop there.
0:04:21 > 0:04:23Other social networks like Instagram, Facebook and even
0:04:23 > 0:04:29Pinterest started to use hashtags.
0:04:29 > 0:04:31The word hashtag is now even in the Oxford English Dictionary.
0:04:31 > 0:04:33Hashtags are used in everything from elections...
0:04:33 > 0:04:36to topics that interest people...
0:04:42 > 0:04:45and even massive TV shows use it to get people talking.
0:04:45 > 0:04:47Now people from all over the world connect using
0:04:47 > 0:04:49hashtags wherever they are.
0:04:49 > 0:04:53Hashtag Newsround #historyofthehashtag!
0:04:53 > 0:04:55That's all from me.
