0:00:12 > 0:00:14Hey, Whitney here.
0:00:14 > 0:00:15It's Wednesday and this is Newsround.
0:00:15 > 0:00:17Your top stories today...
0:00:17 > 0:00:19First, to a refugee swimmer whose story is so amazing,
0:00:19 > 0:00:21it's now being made in to a film.
0:00:21 > 0:00:30I've been finding out all about Yusra Mardini.
0:00:30 > 0:00:33Yusra competed as a swimmer at the Rio Olympics last year.
0:00:33 > 0:00:37But less than a year before that, she was forced to leave her home
0:00:37 > 0:00:42in Syria because of the war.
0:00:42 > 0:00:44When they were telling me that I'm leaving to the Olympics,
0:00:44 > 0:00:49I was also really surprised.
0:00:49 > 0:00:52After only one year, I'm a refugee in Germany and I'm going.
0:00:52 > 0:00:54And there was a Refugee Olympic Team.
0:00:54 > 0:00:55It was incredible.
0:00:55 > 0:00:57She had a great time and took part as a member
0:00:57 > 0:00:59of the first ever Team Refugee.
0:00:59 > 0:01:03But Yusra's life hasn't always been this much fun.
0:01:03 > 0:01:06It took her 25 days to travel from Syria to Europe.
0:01:06 > 0:01:11Part of that journey was in a boat.
0:01:11 > 0:01:14When it began to sink, she got into the sea,
0:01:14 > 0:01:15along with her sister, and helped save 19
0:01:15 > 0:01:21others who were onboard.
0:01:21 > 0:01:25The hero was pulling a rope, you know.
0:01:25 > 0:01:27It's OK, I helped the boat.
0:01:27 > 0:01:30It was not only me, or only my sister.
0:01:30 > 0:01:32But you can imagine that they told you it's 45-minutes trip,
0:01:32 > 0:01:34and you stayed three hours and a half.
0:01:34 > 0:01:37She now lives in Germany and is training for the next
0:01:37 > 0:01:39Olympics, which will be in Tokyo, in 2020.
0:01:39 > 0:01:41My ambition is just to be an athlete.
0:01:41 > 0:01:45If I'm going to start for Germany, or for my country,
0:01:45 > 0:01:48or for the Refugee Olympic Team, I'm going to do the best I can
0:01:48 > 0:01:50and it will be my pleasure.
0:01:50 > 0:01:53Now a film's being made telling her incredible story.
0:01:53 > 0:02:01Let's hope she gets some time at the pool to watch it!
0:02:01 > 0:02:05Let's hope she gets some time out of the pool to watch it!
0:02:05 > 0:02:07Next, if you happen to be in Japan over the weekend,
0:02:07 > 0:02:10you may get to see a couple of shooting stars -
0:02:10 > 0:02:11but they're stars with a difference.
0:02:11 > 0:02:14A company is making their own by releasing metal particles
0:02:14 > 0:02:16from a tiny satelite, which will then burn up as they
0:02:16 > 0:02:17enter the Earth's atmosphere.
0:02:17 > 0:02:20If everything goes to plan, the organisers of the 2020
0:02:20 > 0:02:22Tokyo Olympic and Paralympic Games will feature the man-made shooting
0:02:22 > 0:02:29stars at the opening ceremony.
0:02:29 > 0:02:33Cool!
0:02:33 > 0:02:36So, I want to know - how many of you love using an emoji?
0:02:36 > 0:02:39My personal fave is the heart one.
0:02:39 > 0:02:42But have you ever wondered who decides which ones you get
0:02:42 > 0:02:44to have on your phone or tablet?
0:02:44 > 0:02:53Well, we went to meet one woman who's got that very job.
0:02:53 > 0:02:54My name is Jennifer 8. Lee.
0:02:54 > 0:02:57I'm part of a group that helps to decide the world's emojis.
0:02:57 > 0:02:59What are the things in our world that are important
0:02:59 > 0:03:01enough to be an emoji?
0:03:01 > 0:03:03So, are dinosaurs important enough to be emojis?
0:03:03 > 0:03:09What kind of dinosaurs?
0:03:09 > 0:03:11Certain emoji, like mosquito emoji, is really important,
0:03:11 > 0:03:13because it allows you to communicate the ideas of danger
0:03:13 > 0:03:17without having to know every single language -
0:03:17 > 0:03:21because everyone recognises mosquitoes.
0:03:21 > 0:03:23Some people think that people use emoji because they're really lazy.
0:03:23 > 0:03:26But if you think about it, the reason people love emojis
0:03:26 > 0:03:29so much is that it's a really fast, simple way to communicate ideas,
0:03:29 > 0:03:31and it allows people who don't speak the same language
0:03:31 > 0:03:32to communicate using emoji.
0:03:32 > 0:03:34Sometimes, emoji are really clear.
0:03:34 > 0:03:35But sometimes, it can be really confusing
0:03:35 > 0:03:37what the other person means.
0:03:37 > 0:03:41And some people don't like that.
0:03:41 > 0:03:44And other people think that's what make emoji fun.
0:03:44 > 0:03:47In different cultures, people can give the emoji their own meaning.
0:03:47 > 0:03:52In Japanese, this is how you say thank you.
0:03:52 > 0:03:54But in America - and, sometimes, the West -
0:03:54 > 0:03:56this looks like people praying.
0:03:56 > 0:03:58And some people actually think it looks like a high-five.
0:03:58 > 0:04:00So, you can actually have very different interpretations
0:04:00 > 0:04:08of the different emojis.
0:04:08 > 0:04:10What a cool job!
0:04:10 > 0:04:12So, this was Andy Murray's first match since the Wimbledon
0:04:12 > 0:04:14quarter-finals which he lost, but there was plenty
0:04:14 > 0:04:15of fun to be had.
0:04:15 > 0:04:18That's Murray, in the ginger wig, at a charity event in Glasgow.
0:04:18 > 0:04:22Federer joined in, and played - and won - in a kilt.
0:04:22 > 0:04:25It's also been announced that Andy's wife, Kim, has given birth
0:04:25 > 0:04:26to the couple's second daughter.
0:04:26 > 0:04:30No news on the name yet!
0:04:30 > 0:04:32Congratulations.
