Hi, I'm Ricky,

and this is Newsround.

Stephen Hawking, one

of the world's most

famous scientists, has died.

A spy mystery involving

Russia and the UK.

And we take a look at

the Fantastic Beasts sequel.

First, one of the world's

most famous scientists,

Professor Stephen Hawking,

has died at the age of 76.

I've been looking back

at his incredible life.

Stephen Hawking was passionate

about science and the sky -

even as a child.

He went on to become one of the most

famous scientists of all time,

after studying physics at Oxford

University.

When he was 21, he was told he had

motor neurone disease.

It meant he had to use

a wheelchair and had to talk

through a special computer.

But he lived for 50 years longer

than doctors expected and went

on to develop amazing theories that

changed the way the world thinks

about space, stars and the universe.

I do not have much positive to say

about motor neurone disease, but it

taught me not to pity myself and to

get on with what I can still do.

I am happier now than before

I developed the condition.

His most famous book,

A Brief History of Time, sold more

than 10 million copies

around the world.

A film was made about his life

in 2014, and the actor

who played him, Eddie Redmayne,

won an Oscar for his performance.

Professor Hawking even

appeared in The Simpsons.

His family say he was a great

scientist who was brilliant,

very funny and inspired people

across the world.

He was 76.

Russia has failed to explain

if they had anything to do

with the poisoning of a spy

in the UK.

Theresa May had given them

a deadline of midnight last night.

It's not yet known exactly

what the UK will do next.

Ayshah has more on this.

This is Sergei Skripal.

He's from Russia and was jailed

there more than ten years

ago for being a spy.

But he was released and now lives

here in the UK, in Salisbury.

Just over a week ago, he was found

on a bench in the city centre,

along with his 33-year-old daughter

Yulia.

They were both very poorly.

It's thought they'd been

poisoned deliberately.

It is also thought a police man

was affected by the poison

after going to help find

out what happened.

He's in hospital too.

Skripal spied on Russia,

where he's from, for Great Britain.

And that's why many people

think he has been hurt.

The British Prime Minister

says the poison used

to attack him was made in Russia.

The Government has concluded

that it is highly likely that Russia

was responsible for the act

against Sergei and Yulia Skripal.

But a member of the Russian

government says that's rubbish.

Skripal and his daughter had been

to a restaurant and a pub that day.

People who had also been there have

been told to wash their clothes

they were wearing and any items

they had with them.

Health experts say the risk

to the public is low, though.

Emergency services and Army experts

are investigating and helping

to keep people safe.

Manchester United are out

of the Champions League.

They lost at home to Sevilla.

The away side took control

by scoring a crucial away goal

with less than 20 minutes left.

They went on to score

a second soon after.

The only realistic chance

of silverware left for United this

season is the FA Cup.

Great Britain has won a fifth medal

at the Paralympics in South Korea.

Menna Fitzpatrick -

who's partially sighted -

and her guide Jen Kehoe have

won their third medal

after finishing second

in the women's visually impaired

giant slalom in Pyeongchang.

They've already won silver

in the super combined and bronze

in the super-G race.

The first official trailer for J K

Rowling's Fantastic Beasts sequel,

The Crimes of Grindlewald,

has just been released.

Warner Brothers have revealed more

details of the plot and characters

and Harry Potter fans are getting

very excited indeed.

Jude Law plays a young

Professor Dumbledore.

Eddie Redmayne returns

as Newt Scamander.

Plus there are loads of

new fantastic beasts and characters.

It's released on 16th

November this year.

That's all from us.

We're back in just

over half an hour.
