Hi, I'm Ricky, it's Wednesday, it's 4.20pm and I've got

today's top stories, live on Newsround.

This is what we've got for you in the next few minutes:

Why scientists are getting up close with panda poo.

And stayed tuned for the fastest snowboarder in Britain.

First, the Queen's 90th birthday celebrations got

Although the big day isn't until tomorrow,

hundreds of kids were invited to Windsor Castle to sing songs

God save our gracious Queen. It is a big day for these kids, they have a

VIP guest to impress and it is time to exercise their vocals. They are

performing a number of songs in front of the Queen. The children go

to a school close to Windsor Castle, where the Queen spends a lot of her

time. Along with other children they will kick-start the Queen's 90th

birthday celebrations. And while a feeling? It is quite exciting to see

the Queen because not many people have seen the Queen. In front of

Prince Philip and the Queen and other people, it is really freaky.

The children today stood in front of their special guest their hearts

out. Today we met the Queen and Prince Philip and some other people.

In a way it is not scary because you are singing with other schools. I

thought she would wear blue but she wore pink. I thought she would come

straight to us and I did not know what to say if she had asked a

question. It was really, truly amazing to me the Queen because this

is like a once-in-a-lifetime experience, it doesn't come up every

day. The Queen's grandson

the Duke of Cambridge Some newspapers claim that

since Prince William left his job as an RAF pilot back in 2013,

he's spent too much time going on holidays and relaxing

with his family, and not enough time doing royal duties

like helping charities. But the prince has hit back saying

he takes his responsibilities To be honest, I am going to get

plenty of criticism over my lifetime and it is something that I don't

completely ignore but it is not something I'd take completely to

heart. When the Queen decides that she is going to hand down more

responsibilities I will be the first person to accept them.

The UK's only giant pandas, Sunshine and Sweetie,

are taking part in a special project looking at their poo.

Animal experts from Edinburgh zoo are collecting and investigating

what's in the poo to understand more about the animals' eating habits.

It's hoped the research will help the animals in the wild

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

Take a look at Europa, the moon of Jupiter.

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

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.

Next, being part of an after-school club can help

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 she goes to dancing club and it

Suhas in Newcastle is a fan of after school clubs too,

he says since he's been getting active, he reckons he's become more

And Milly-Jo goes to gymnastics after school she says it

Thank you to everyone who sent in messages.

You can check out more of them online.

Finally to the fastest snow boarder in Britain.

This is Jamie Barrow reaching more than 94 miles an hour

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

he didn't come close to the world record,

held by a Frenchman who went over 126 miles per hour last year.

That's all from me, Newsround's back tomorrow morning at 7.40am.
