Hi, I'm Ricky, live on CBBC.

Coming up on Newsround:

There's big dino news from over 200 million years ago.

We say happy 200th birthday to rollercoasters.

And how dragons and vampires are helping humans.

First up, football, and Leicester City still have a chance

to get to the next stage of the Champions League

despite a 1-0 defeat in Spain to Atletico Madrid.

The only goal came after a controversial penalty

when Marc Albrighton's foul looked to be outside the box.

Well, we spoke to some Leicester fans to find out

what they made of it.

I think they did all right.

It's just, the ref shouldn't have gave

that penalty.

It should have been a free kick outside the box.

When I saw it, and the referee pointed out

the spot, I was like, what, that's not a penalty,

that's a free kick!

It cost Leicester the game, which they could have won.

It shouldn't have been a penalty.

I was really mad about that.

I'm sad cos Leicester lost.

They did have a couple good chances, but just

couldn't put them away.

1-0 is pretty all right, because they're doing

pretty well in the Champions League.

Next, ever wondered who'd win in a fight -

dinosaur or crocodile?

Well, you don't have to choose, because researchers have discovered

the fossil of a creature that was a bit of both.

There aren't many animals older than a dinosaur, right?

They lived 230 million years ago!

Well, think again.

Crocodile-like creatures were around way before that,

over 300 million years ago.

Now, researchers think they've found out

how the crocodiles first evolved into dinosaurs - by studying

a fossil of a creature called a teleocrater.

In many ways, this animal is a missing link between

dinosaurs and crocodiles,

and shows how some of the features that previously just

appeared in dinosaurs actually first evolved.

For example, dinosaurs start off as two-legged animals,

whereas most of their ancestors seem to be four-legged.

This animal shows how the transition between a four-legged

crocodile-like animal and the two-legged dinosaur happened.

Studying the teleocrater bones also showed researchers that some

dinosaur features evolved much earlier than they'd first thought.

All hail the croco-saur!

If you love roller coasters, then this one is for you.

Because today marks 200 years since the first one was built.

It opened in Paris in France in 1817 and wasn't much more

than a rickety wooden cart on a track.

Things have changed a bit since then with modern coasters - bigger,

faster and much more exciting.

But I think I'll stick to the teacups.

We're inspired by animals for all sorts of things,

like robots, transport, and even our clothes!

But did you know some of them are helping us

to invent cures for diseases?

Dragons and vampires may be pretty scary,

but did you know they're actually helping humans?

So, OK, we're not talking about this kind of dragon.

We mean Komodo dragons!

These fearsome reptiles have around 80 different types of bacteria

living in their spit, but for some reason,

they don't get sick from it.

So scientists think they must have really good immune systems,

to help them fight disease.

A group of scientists in America investigated the dragon's blood.

They found that it actually helped to fight infections

and speed up healing time.

Amazing!

But it's not just Komodo dragons who've been helping us.

Some jellyfish have special chemicals in them

which make them glow.

Doctors have made dye inspired by the jellyfish to help them find

tumours in the body.

As for vampires, well, it's not quite what you might be thinking.

No, not these blood suckers,

but vampire bats.

Their spit contains something which thins blood to help them feed.

Scientists have used this to develop medicine to help stop

dangerous blood clots in humans.

Talking of helpful animals, meet Parrow.

He's a robotic seal who was created to help older people

living in care homes in Japan.

He looks and feels like the real thing, and is covered in sensors

that means he can respond when he's touched or spoken to.

The residents seem to like him.

Finally, police officers were given the runaround in London yesterday.

A pig caused chaos when it escaped and trotted

through lunch-time traffic.

A jogger had to dodge the animal,

who seemed to take a liking to his outfit!

The pig was eventually caught and returned to its owner.

That's all from me.
