Hey everyone, Leah here with the latest

from Newsround here on CBBC.

Coming up today...

BFG star Ruby answers your questions.

The animal lover getting ready to fly with swans,

and the trampoline superstar who's just won a big competition.

First to some big Olympic news today.

Track and field athletes from one of the biggest countries

in the world - Russia, will be banned from competing

at this summer's Games in Rio.

This is the story so far.

Russia is one of the most successful countries in Olympic history,

having won many medals in athletics.

But they won't be adding to their medal tally

this summer in Rio.

The country's track and field team aren't allowed to compete

in the Olympics because lots of them have been cheating.

They have been found guilty of doping.

That is when people use banned drugs to cheat and give themselves

an unfair advantage in competitions.

The Russian Olympic Committee and 68 athletes argued against the decision

to ban them by the organisation which runs world athletics.

But the ruling has not changed.

Things could get worse for all of Russia's sportsmen and women.

There are calls to ban all the country's teams

from the Games as experts look into whether or not other athletes

have also broken the rules.

And you can find out more about how athletes are tested for drugs

in our online guide.

Football now, because it's thought that Sunderland boss Sam Allardyce

will be confirmed as the new England manager later today.

Allardyce has been at Sunderland for the last nine months,

and managed to keep his team in the Premier League last season.

He's thought to have met with the Football Association

last week to talk about replacing Roy Hodgson, who quit in June

after England's humiliating defeat to Iceland in the Euros.

From footy to a sport that you may not know too much

about...

Trampoline Gymnastics.

The sport involves hurtling down a runway at top speed,

before launching yourself into the air

to perform a series of high-flying stunts.

This is 15-year-old Harrison from Leeds and he's just won

the national title in the Double Mini Trampoline

to become the new British Champion.

It feels really good.

I am really happy with how I performed.

I scored the best I have ever scored in a competition

so I am really happy with how I did.

I love running up to it and when I jump onto the trampoline

and go really high, it feels really good.

Now to one of the biggest and possibly friendliest films

of the summer.

Roald Dahl's classic book the BFG has been turned into a film.

One of the stars of the movie is Ruby Barnhill who plays Sophie.

Earlier, she came into the studio and Ayshah

asked her some of your questions.

Hope from Aberfeldy in Scotland wanted to know how Ruby felt

during filming?

I was really, really nervous when we started filming

because it was such a big thing for me.

I was unsure about everything.

But then Steven, the director of the film and Mark who plays

the BFG, and everyone on set made me feel really, really comfortable

so that helped a lot.

It must have helped a lot.

Fara in Surrey asks, how did it feel to pretend

there was an actual giant there when you were filming?

What was that like to pretend?

Mark Rylance was there all of the time actually,

on a scissor lift, so I would have somebody to look at and Mark

would kind of do the body movements of the BFG

and the physical movements.

But I think most actors and actresses would say

it was quite unusual, but because this was my first film,

it was interesting so I enjoyed it.

One last one, Isabel in Devon says what is your

favourite Roald Dahl book?

The first Roald Dahl book I read was Fantastic Mr Fox...

Me too!

And I still really love that.

I also really love George's Marvellous Medicine.

Well, since it's summer holiday season, we've been asking you

what you're planning to get up to.

Here are some of your comments.

Jessica in London says, I'm going to be seeing my cousins

and going to Wales.

Victoria in the West Midlands says, I am going camping in Wales and then

going to Cornwall for four days.

Alexander in London says, I am going to Peru with my sister,

mum, dad and grandma.

And Brooke in Rotherham says, I am going to Skegness and

my mum and dad are getting married.

And finally the Bewick swans making their Autumn migration

from Russia to the UK are going to have company this year.

Conservationist Sacha Dench is going to go with them

using a motor parachute to try to find out

why their numbers are in decline.

She's been training to fly thousands of miles with the birds

including over the North Sea.

That's all from me, Newsround's back in the morning

with news about Drake, Robot wars and loads more.

Bye-bye.
