Hi, I'm Leah and you're watching Newsround live on CBBC.

Keep watching, there's all this coming up:

Why scientists are getting up close with panda poo.

And William and Harry join the Force.

But first, being part of an after-school club

That's what new research out today says.

We've been asking if after-school activities make a difference

Hollie from Carnoustie in Scotland says that she goes to dancing club

Keira from Cheshire thinks after-school clubs make her want

to concentrate more on her work to make the day go faster.

And Milly-Jo from Somerset goes to gymnastics after school

and she thinks it helps her at school.

Thanks for all of those, please keep sending them in online.

Here's what kids at an after-school club in Manchester thing.

Throughout the day, if you've got an after-school club, like, you are

focusing on that and it makes you happy to know that after school,

you're going to be doing sports instead of just maybe sitting

around, watching telly in your house.

When you go to after-school clubs, you are like spending time

with your friends and having a bit of a mess around.

After-school club, it motivates me to do better in my work

so that the day ends faster and I can get on

It helps me relax after a hard day at school but I haven't had

After-school, I think it is fun because you get to spend a long

day in class and then some time outside with your friends.

Princes William and Harry popped to the set of Star Wars

at Pinewood Studios in Buckinghamshire in England,

where they battled each other with lightsabers.

After meeting some of the cast, William joked he couldn't stop

Kensington Palace said the tour was organised to celebrate

Next, want to see what a fire tornado looks like?

Well, here's one caught on a mobile phone in Alberta in Canada.

This is the moment a brush fire was whipped up into the air

and became a fire tornado within seconds.

The fire was sparked by a campfire that got out of control

Firefighters managed to control the blaze.

Jenny took up this one for us. Take a look.

Sunshine and Sweetie arrived in Edinburgh from China in 2011.

We were all gripped by panda fever as the nation waited to find out

if there was going to be a panda pregnancy or not.

Now Sunshine and Sweetie are taking part in a project

a little less glamorous and a lot more smelly.

The pandas are having their poo collected and investigated as part

of a project to understand more about the animals' eating habits.

We need to understand exactly which species of bamboo

that pandas in the wild are eating.

The first place to start all that

At the moment, we are gathering one poo from each panda

Next, off to the lab to investigate the poo a bit more closely.

So after the poo has been collected, it comes here -

what's the process, how do you analyse it?

Once we get it from the zoo, it looks like this.

We take this and we go through a process to extract the DNA

DNA is basically the building block of life, every single thing has it

and we look at that to try and tell apart which different species

It's not just the pandas at Edinburgh Zoo that

We are going to be looking at wild pandas in China and hopefully

finding samples they have left behind for us and it will give us

all sort of information about what sort of things pandas are eating.

It's really hard to work out what giant pandas are eating,

which makes it really difficult for places like the zoo to make sure

they are feeding them exactly what they need.

We are really excited that, by working out exactly

what they are eating, we can actually help not only

conserve them in the wild but also hopefully help Edinburgh Zoo breed

Even though looking into panda poo might be a bit smelly,

and even seem a bit strange, it shows that eating

the right stuff is important for all of us to stay healthy,

And the results might even help Edinburgh Zoo

Take a look at Europa - the moon of Jupiter.

Scientist say they're keen to launch a mission there in around

They're meeting in Paris this week to consider the best options.

It's likely they'll send a probe to explore the icy surface

in the hope of finding out more about our solar system.

In the Premier League, Newcastle United could only

manage a point against Manchester City last night.

City took the lead at St James Park with this Sergio Aguero header.

But Newcastle managed to hit back before half time.

1-1 the final score but Newcastle remain two points from safety.

And finally, want to see the fastest snowboarder in Britain?

This is Jamie Barrow reaching more than 94mph in the French Alps.

It's a new British record, but if you think that's impressive,

he didn't come close to the world record, held

by the Frenchman Edmond Plawczyk, who went at over 126mph last year.
