Hello everyone, I hope you're all having a good weekend.

Here's what's coming up on Newsround:

Stay tuned for the incredible dinosaur discovery.

And epic weather pictures as a huge snow storm hammers

America's east coast.

But first to our top story, and it's a stinker.

A team in London are going to extreme lengths to try to stop

dog poo on our streets.

Ricky's been sniffing this story out.

Dog poo.

It's pretty gross, isn't it?

You're having a nice stroll in the park, then

all of a sudden, ugh!

You come across that!

Don't you just hate it when some people don't

clean up their dog's mess?

If only there was a way of finding out who did this?

I think this might be a job for the DPIU,

the Dog Poo Investigation Unit.

OK, so there is no such thing as a Dog Poo Investigation Unit,

but one local council in London is getting

tough on dog doo-doo.

Barking and Dagenham council have launched a scheme to test dog poo,

to try and catch owners who fail to clear up after their pets.

Park Rangers will collect samples of dog mess and send

it to a lab for DNA testing.

Scientists will be comparing the DNA found in the samples with a list

of registered dogs, and then the owner

will be tracked down and fined.

Getting DNA from dogs involves a simple swab,

taking just a few seconds.

It will also help if the dog is ever lost.

Registering for this scheme is voluntary at the moment,

but some people think that not all pet owners will sign up.

A responsible dog owner will walk around with a bag in his pocket

and pick it up.

I think this is a waste of money.

It's not realistic at all, in all honesty.

It's not going to work.

Barking Council say the doggy forensics will help keep the area

clean and mess-free, inviting other councils

to follow suit.

So is this idea barking mad, or will it actually stop owners

and their dogs leaving this mess behind?

Tell you what, I'm going home, that's enough dog poo for me today.

A ban on all fires has been issued in one state in Australia

as firefighters try to tackle blazes there.

It means that no open fires, such as campfires, will be allowed

over the next four days.

Authorities hope it will give fire crews a chance to bring more

than 70 fires burning across Tasmania under control.

Now, to the huge snow storm that's hitting the east coast of America.

A state of emergency has been declared across six states,

including the capital Washington, DC.

Public transport has been cancelled in many places and people have been

advised to stay indoors until the storm passes.

Forecasters are predicting it'll be the heaviest snowfall in 100 years,

with more than two feet of snow and winds of more than 50mph.

We've been sent this special report from two kids in Washington

where school has been cancelled.

I'm Kara.

And I'm Julia.

And we had a snow day today.

We live in Washington, DC.

Today we were supposed to be expecting 30 inches.

Of snow.

It would have been 12, but tomorrow we are going to have 30

inches of snow, right here in Washington, DC.

And for tomorrow, we are making a sledding path that goes

OK?

And then we're going to turn left and then we're going to do a

snow dance like this.

Go snow, go snow!

Next, wildlife presenter Sir David Attenborough says he has

uncovered the world's biggest dinosaur in his latest documentary.

Our Leah has been to meet him to find out more.

A digital version of a titanosaurus.

But could this computer-generated dinosaur ever become a reality?

Sir David Attenborough, who was recently

part of the team that uncovered the bones of this giant creature,

believes anything is possible.

Do you think there is a possibility that scientists could bring back

dinosaurs from extinction?

It would be very, very expensive to do.

He believes the money would be better spent looking after animals

around today.

Plus, there would be no space for them.

Where would the poor thing go?

Where are you going to put him?

You've got enough problems keeping elephants and

finding space for them.

Where are you going to fit a dinosaur that is ten

times bigger than an elephant?

But he was blown away by discovery made by a team of experts.

This is its thighbone.

They found over 200 separate bones.

So we can be pretty sure what the animal looked like.

It was very, very, very, big.

That was a real excitement to see that.

For Sir David, discovering fossils is still so exciting,

and he believes there is so much more to find.

Tennis, and Andy Murray is through to the fourth

round of the Australian Open after beating Portugals Joao Sousa

by three sets to one.

He will play either Bernard Tomic or John Millman in his next match.

If that wasn't exciting enough, Yohanna Konta has become the first

British woman since 1987 to make it to the last 16

of the Australian Open.

Konta thrashed Czech Republic's Denisa

Allertova 6-2, 6-2 in Melbourne.

That's all from me, Newsround's back right here at around 2pm.

See you then.
