0:00:00 > 0:00:01but snatched a late win at home to Stoke.
0:00:01 > 0:00:04See you.
0:00:15 > 0:00:18Hi, I'm Ayshah and this is Newsround.
0:00:18 > 0:00:21First, people in Bali in Indonesia have been warned that a volcano
0:00:21 > 0:00:23on the island could erupt at any time.
0:00:23 > 0:00:25Mount Agung has been sending clouds of thick ash and smoke
0:00:25 > 0:00:27into the air since Saturday.
0:00:27 > 0:00:30The airport on the island is now closed and people
0:00:30 > 0:00:37are being moved away from the area to keep them safe.
0:00:37 > 0:00:39In the football, Manchester City are still unbeaten at the top
0:00:39 > 0:00:43of the table after winning 2-1 against Huddersfield Town.
0:00:43 > 0:00:52This goal by Raheem Sterling eventually got them their win.
0:00:52 > 0:00:56But they had to come from 1-0 down to beat the Premier League new boys.
0:00:56 > 0:00:58They are now eight points clear of rivals Manchester United
0:00:58 > 0:01:00at the top of the table.
0:01:00 > 0:01:02And in Scotland, Celtic have won the Scottish League Cup
0:01:02 > 0:01:05for the second year in a row, after beating Motherwell
0:01:05 > 0:01:062-0 at Hampden Park.
0:01:06 > 0:01:11The goals came from winger James Forrest and stiker Moussa Dembele.
0:01:11 > 0:01:14You might recognise these famous faces, but they've all hit
0:01:14 > 0:01:16the headlines in the last few days for the wrong reasons.
0:01:16 > 0:01:21So, what's going on?
0:01:21 > 0:01:24I want to start off with that I'm sorry, and I'm just
0:01:24 > 0:01:25really, really sorry.
0:01:25 > 0:01:27YouTuber Jack Maynard has left ITV's I'm A Celebrity,
0:01:27 > 0:01:28Get Me Out Of Here!
0:01:28 > 0:01:31Zoella and Stormzy have both apologised.
0:01:31 > 0:01:33Why?
0:01:33 > 0:01:36It's because of offensive comments they made years ago on Twitter.
0:01:36 > 0:01:40What do some of you make of it?
0:01:40 > 0:01:43They said they didn't know that they were going to be
0:01:43 > 0:01:46celebrities, but no matter who you are, you've got to be
0:01:46 > 0:01:49careful of the words that you use.
0:01:49 > 0:01:52If someone does post something bad, that's in the past,
0:01:52 > 0:02:00everyone makes mistakes.
0:02:00 > 0:02:02They should have thought about what they said
0:02:02 > 0:02:03before they did it.
0:02:03 > 0:02:05If it was a long time ago, people can change
0:02:05 > 0:02:06and their opinions can change.
0:02:06 > 0:02:08Zoella, Stormzy and Jack Maynard have now deleted
0:02:08 > 0:02:10a number of their old tweets, which included insulting
0:02:10 > 0:02:12views and language.
0:02:12 > 0:02:15Stormzy said his comments were "unacceptable and disgusting".
0:02:15 > 0:02:18Zoella said, "I'm sorry if I ever offended anyone."
0:02:18 > 0:02:20And Jack Maynard went online to say this.
0:02:20 > 0:02:22I messed up.
0:02:22 > 0:02:24I've been really stupid in the past.
0:02:24 > 0:02:28Growing up online is hard.
0:02:28 > 0:02:31All I can do is just beg and encourage that you guys don't
0:02:31 > 0:02:32make the same mistake as well.
0:02:32 > 0:02:37Don't ever put anything online that you wouldn't say to your mum.
0:02:37 > 0:02:39Newsround asked one expert what he thinks you should do
0:02:39 > 0:02:42before posting comments.
0:02:42 > 0:02:44Don't be insulting, don't be racist, don't
0:02:44 > 0:02:47use offensive language.
0:02:47 > 0:02:49You're leaving a digital footprint, and those messages that
0:02:49 > 0:02:52you send on social media are there to be discovered forever.
0:02:52 > 0:02:54Don't send something just for the sake of it,
0:02:54 > 0:02:57just to be popular, just to get the retweets, just to get
0:02:57 > 0:02:59the shares, it's just not worth it.
0:02:59 > 0:03:02Has this made a difference to what some of you might be
0:03:02 > 0:03:12posting online in future?
0:03:15 > 0:03:19When you think, by deleting something, you think it's gone when,
0:03:19 > 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 > 0:03:30on social media, otherwise it could come back to haunt you.
0:03:30 > 0:03:33My dad always used to tell me, don't post anything you wouldn't be
0:03:33 > 0:03:36comfortable to show your grandad or your grandma, so I always think
0:03:36 > 0:03:37about that before I post.
0:03:37 > 0:03:38Remember, what goes online, stays online.
0:03:38 > 0:03:41Now, the last thing you want when you're exploring another
0:03:41 > 0:03:42planet is a flat tyre.
0:03:42 > 0:03:45Well, Nasa has created a new one to help avoid this happening.
0:03:45 > 0:03:46These aren't just any old tyres.
0:03:46 > 0:03:49These are Nasa's new airless chainmail ones.
0:03:49 > 0:03:52They look pretty cool, and they've been designed to cope better
0:03:52 > 0:03:54with the rocky surfaces of other planets like Mars.
0:03:54 > 0:03:59They're made from a material which has its own memory.
0:03:59 > 0:04:01After it's rolled over something, it can remember its original shape.
0:04:01 > 0:04:06This particular material doesn't deform like conventional materials
0:04:06 > 0:04:09where, in those materials, when we put stress on them,
0:04:09 > 0:04:15we basically are stretching the bonds between the structures.
0:04:15 > 0:04:22This has a unique characteristic that allows it to do
0:04:22 > 0:04:26anatomic rearrangement to accommodate deformation.
0:04:26 > 0:04:29We could actually deform this all the way down to the axle
0:04:29 > 0:04:31and have it return to shape.
0:04:31 > 0:04:37Sounds very high-tech and a bit complicated,
0:04:37 > 0:04:40but essentially what it means is even if the tyre gets really
0:04:40 > 0:04:42squashed, it won't burst or break, but will bounce back.
0:04:42 > 0:04:46That will come in handy when it has to drive over those big space rocks.
0:04:46 > 0:04:50Now, that is tyre-rific.
0:04:50 > 0:04:52I'm back in half-an-hour with some important panda news.
0:04:52 > 0:04:56Bye.
