0:00:12 > 0:00:15Hello, I'm Hayley with all today's news including the top sporting
0:00:15 > 0:00:16sction from the weekend.
0:00:16 > 0:00:19First to the Premier League where Manchester United beat Arsenal
0:00:19 > 0:00:203-1 in a thriller last night.
0:00:20 > 0:00:23United's goals came from Antonio Valencia
0:00:23 > 0:00:24and two by Jesse Lingard.
0:00:24 > 0:00:27Arsenal tried to fight back but they were stopped by a string
0:00:27 > 0:00:30of outstanding saves from United goalkeeper David de Gea.
0:00:30 > 0:00:34But it was a bad night for United's Paul Pogba who was sent
0:00:34 > 0:00:40off for this tackle.
0:00:40 > 0:00:45He'll now miss the Manchester City derby next weekend.
0:00:45 > 0:00:48Liverpool beat Brighton 5-1 - Roberto Firmino scored twice -
0:00:48 > 0:00:51sending the reds to fourth in the table.
0:00:51 > 0:00:55Everton won in Sam Allardyce's first match in charge,
0:00:55 > 0:00:58beating Huddersfield 2-0 thanks to goals from Gylfi Sigurdsson
0:00:58 > 0:01:08and Dominic Calvert-Lewin.
0:01:09 > 0:01:11Now the last thing you want when you're exploring another
0:01:11 > 0:01:12planet is a flat tyre.
0:01:12 > 0:01:15Well, Nasa has created a new one to help avoid this happening.
0:01:15 > 0:01:17These aren't just any old tyres.
0:01:17 > 0:01:19These are NASA's new airless chainmail ones.
0:01:19 > 0:01:23They look pretty cool and they've been designed to cope better
0:01:23 > 0:01:26with the wonky surfaces of other planets like Mars.
0:01:26 > 0:01:29They're made from a material which has its own memory.
0:01:29 > 0:01:34After it's rolled over something, it can remember its original shape.
0:01:34 > 0:01:37This particular material doesn't deform like conventional materials,
0:01:37 > 0:01:40where in those materials, when we put stress on them,
0:01:40 > 0:01:45we basically are stretching the bonds between the atomic structures.
0:01:45 > 0:01:52This material has a unique characteristic that allows it to do
0:01:52 > 0:01:55an atomic rearrangement, to accommodate deformation.
0:01:55 > 0:02:00We can actually deform this all the way down to the axle
0:02:00 > 0:02:02and have it return to shape.
0:02:02 > 0:02:06Sounds very high-tech and a bit complicated, but essentially,
0:02:06 > 0:02:10what it means is even if the tyre gets really squashed,
0:02:10 > 0:02:12it won't burst or break but will bounce back.
0:02:12 > 0:02:16That'll come in handy when it has to drive over those big space rocks.
0:02:16 > 0:02:26Now that's tyre-rific!
0:02:26 > 0:02:29Next, if you like gymnastics this one's for you.
0:02:29 > 0:02:30Two sporty sisters and their story.
0:02:30 > 0:02:31Hi, I'm Katie.
0:02:31 > 0:02:32And I'm Izzy.
0:02:32 > 0:02:34And you might have guessed, we're twins.
0:02:34 > 0:02:36Izzy's a brilliant gymnast and when we were younger,
0:02:36 > 0:02:40she used to compete at national level on bar and beam.
0:02:40 > 0:02:42But she had a really bad ankle injury a few years ago,
0:02:42 > 0:02:44which stopped her competing.
0:02:44 > 0:02:47So how did it feel when you hurt your ankle, and you thought that
0:02:47 > 0:02:49you wouldn't be able to do gymnastics again?
0:02:49 > 0:02:54Well, I was really disappointed and upset, because gymnastics
0:02:54 > 0:02:57was everything to me and to think that I wouldn't be able to do it
0:02:57 > 0:02:59again just really upset me.
0:02:59 > 0:03:01Was it really hard watching me?
0:03:01 > 0:03:05I mean, it was taking a long time to get better and I knew
0:03:05 > 0:03:08I would get there eventually but when I was waiting to be able
0:03:08 > 0:03:10to do things and join in with any kind of sport
0:03:10 > 0:03:13again, and I was watching you while I was coaching,
0:03:13 > 0:03:16it just made me really frustrated that I couldn't just jump
0:03:16 > 0:03:18and jump onto the floor and join in with you.
0:03:18 > 0:03:21How does it make you feel being able to do gymnastics again?
0:03:21 > 0:03:24It makes me feel really happy and delighted that I can do
0:03:24 > 0:03:30the sport that I love and I'm so thankful that my injury
0:03:30 > 0:03:32didn't stop me from doing gymnastics altogether.
0:03:32 > 0:03:35This weekend, we are heading to the London Festival of gymnastics
0:03:35 > 0:03:38and this will be the first time since we were younger
0:03:38 > 0:03:40that we have performed together.
0:03:40 > 0:03:42How are you feeling about performing at the Festival?
0:03:42 > 0:03:48Really excited because it's my big performance with everybody and a bit
0:03:48 > 0:03:53nervous, but mostly excited and ready to do it.
0:03:53 > 0:04:11It was really fun because I haven't really done
0:04:11 > 0:04:12anything like that before.
0:04:12 > 0:04:20It was actually really exciting.
0:04:20 > 0:04:21Now forget texting, snapchatting
0:04:21 > 0:04:22or instagramming your mates.
0:04:22 > 0:04:25These kids in Kidderminster are going old school...
0:04:32 > 0:04:37Dear dad, and to so much for your very lovely and well-written letter.
