0:00:07 > 0:00:10Ever hit post and regretted it?
0:00:10 > 0:00:13Celebs tell us why we should be careful on social media.
0:00:13 > 0:00:23And, more help for pandas in China.
0:00:26 > 0:00:29First, people in Bali in Indonesia have been warned that a volcano
0:00:29 > 0:00:33on the island could erupt at any time.
0:00:33 > 0:00:36Mount Agung has been sending clouds of thick ash and smoke
0:00:36 > 0:00:39into the air since Saturday.
0:00:39 > 0:00:41The airport on the island is now closed, and people
0:00:41 > 0:00:46are being moved away from the area to keep them safe.
0:00:46 > 0:00:48In the football, Manchester City are still unbeaten at the top
0:00:48 > 0:00:51of the table after winning 2-1 against Huddersfield Town.
0:00:51 > 0:00:54This goal by Raheem Sterling eventually got City their win.
0:00:54 > 0:00:57But they had to come back from 1-0 down to beat
0:00:57 > 0:01:01the Premier League new boys.
0:01:01 > 0:01:04They are now eight points clear of rivals Manchester United
0:01:04 > 0:01:07at the top of the table.
0:01:07 > 0:01:11And in Scotland, Celtic have won the Scottish League Cup
0:01:11 > 0:01:13for the second year in a row, after beating Motherwell
0:01:13 > 0:01:152-0 at Hamden Park.
0:01:15 > 0:01:20The goals came from winger James Forrest and stiker Moussa Dembele.
0:01:20 > 0:01:22You might recognise these famous faces, but they've all hit
0:01:22 > 0:01:25the headlines in the last few days for the wrong reasons.
0:01:25 > 0:01:29So, what's going on?
0:01:29 > 0:01:32I want to start off with that I'm sorry, and I'm just
0:01:32 > 0:01:34really, really sorry.
0:01:34 > 0:01:38YouTuber Jack Maynard has left ITV's I'm A Celebrity, Get Me Out Of Here!
0:01:38 > 0:01:42Zoella and Stormzy have both apologised.
0:01:42 > 0:01:44Why?
0:01:44 > 0:01:47It's because of offensive comments they made years ago on Twitter.
0:01:47 > 0:01:51What do some of you make of it?
0:01:51 > 0:01:54They said they didn't know that they were going to be
0:01:54 > 0:01:58celebrities, but no matter who you are, you've got to be
0:01:58 > 0:02:00careful with the words that you use.
0:02:00 > 0:02:02If someone does post something bad, that's in the past,
0:02:02 > 0:02:04everyone makes mistakes.
0:02:04 > 0:02:05They should have thought about what they said
0:02:05 > 0:02:06before they did it.
0:02:06 > 0:02:09If it was a long time ago, people can change
0:02:09 > 0:02:14and their opinions can change.
0:02:14 > 0:02:17Zoella, Stormzy and Jack Maynard have now deleted a number
0:02:17 > 0:02:20of their old tweets, which included insulting
0:02:20 > 0:02:22views and language.
0:02:22 > 0:02:25Stormzy said his comments were "unacceptable and disgusting".
0:02:25 > 0:02:30Zoella said, "I'm sorry if I ever offended anyone."
0:02:30 > 0:02:32And Jack Maynard went online to say this.
0:02:32 > 0:02:37I messed up.
0:02:37 > 0:02:39I've been really stupid in the past.
0:02:39 > 0:02:40Growing up online is hard.
0:02:40 > 0:02:43All I can do is just beg and encourage that you guys don't
0:02:43 > 0:02:45make the same mistake as well.
0:02:45 > 0:02:48Don't ever put anything online that you wouldn't say to your mum.
0:02:48 > 0:02:52Newsround asked one expert what he thinks you should do
0:02:52 > 0:02:54before posting comments online.
0:02:54 > 0:02:56Don't be insulting, don't be racist, don't use offensive language.
0:02:56 > 0:03:01You're leaving a digital footprint, and those messages that
0:03:01 > 0:03:03you send on social media are there to be discovered forever.
0:03:03 > 0:03:05Don't send something just for the sake of it,
0:03:05 > 0:03:08just to be popular, just to get the retweets, just to get
0:03:08 > 0:03:10the shares - it's just not worth it.
0:03:10 > 0:03:13Has this made a difference to what some of you might be
0:03:13 > 0:03:15posting online in future?
0:03:15 > 0:03:18When you think, by deleting something, you think it's gone when,
0:03:18 > 0:03:21in reality, it's not, it's never gone, so it just makes
0:03:21 > 0:03:24you realise you've got to be really, really careful what you post.
0:03:24 > 0:03:27Everyone, not just celebrities, need to think about what you post
0:03:27 > 0:03:32on social media, otherwise it could come back to haunt you.
0:03:32 > 0:03:36My dad always used to tell me, "Don't post anything you wouldn't be
0:03:36 > 0:03:38comfortable to show your grandad or your grandma," so I always think
0:03:38 > 0:03:40about that before I post.
0:03:40 > 0:03:43Remember, what goes online, stays online.
0:03:43 > 0:03:45Cricket now, and it wasn't the best start for England
0:03:45 > 0:03:47in the Ashes tournament, as they lost the first
0:03:47 > 0:03:52match yesterday.
0:03:52 > 0:03:55Despite a promising start to the game, Australia won easily.
0:03:55 > 0:03:57The English side can still win the tournament if they draw
0:03:57 > 0:03:59or win the next game.
0:03:59 > 0:04:02In netball, England beat Malawi at a fierce match in London.
0:04:02 > 0:04:03They had a tricky start, though.
0:04:03 > 0:04:06But they fought back to win 61-53.
0:04:06 > 0:04:08There's still one more match in this series, and that's
0:04:08 > 0:04:16on Wednesday in Birmingham.
0:04:16 > 0:04:19Now, the last thing you want when you're exploring another
0:04:19 > 0:04:20planet is a flat tyre.
0:04:20 > 0:04:24Well, Nasa has created a new one to help avoid this happening.
0:04:24 > 0:04:25These aren't just any old tyres.
0:04:25 > 0:04:28These are Nasa's new airless chainmail ones.
0:04:28 > 0:04:32They look pretty cool, and they've been designed to cope
0:04:32 > 0:04:36better with the rocky surfaces of other planets like Mars.
0:04:36 > 0:04:39They're made from a material which has its own memory.
0:04:39 > 0:04:43After it's rolled over something, it can remember its original shape.
0:04:43 > 0:04:48This particular material doesn't deform like conventional materials
0:04:48 > 0:04:51where, in those materials, when we put stress on them,
0:04:51 > 0:04:55we basically are stretching the bonds between the structures.
0:04:55 > 0:05:05This has a unique characteristic that allows it to do
0:05:06 > 0:05:07anatomic rearrangement to accommodate deformation.
0:05:07 > 0:05:10We could actually deform this all the way down to the axle
0:05:10 > 0:05:12and have it return to shape.
0:05:12 > 0:05:14Sounds very high-tech and a bit complicated,
0:05:14 > 0:05:18but essentially what it means is even if the tyre gets really
0:05:18 > 0:05:21squashed, it won't burst or break, but will bounce back.
0:05:21 > 0:05:25That will come in handy when it has to drive over those big space rocks.
0:05:25 > 0:05:30Now, that's tyre-rific!
0:05:30 > 0:05:35Finally, we love panda news on Newsround, so let's hear some.
0:05:35 > 0:05:38Two countries, China and Indonesia, are working together on a research
0:05:38 > 0:05:42project to help the animals.
0:05:42 > 0:05:44Two pandas, Hu Chun and Cai Tao, have been flown
0:05:44 > 0:05:45from China to Indonesia.
0:05:45 > 0:05:49They'll live there for the next ten years.
0:05:49 > 0:05:54That's it for Monday morning's Newsround, enjoy your day.
0:05:54 > 0:05:58Don't forget you can head online for the rest of the news,
0:05:58 > 0:06:01bye!
