Afternoon folks, Martin here with Saturday's

best news stories.

On the way...

A very stinky story...

And from poo to Who, with some exciting news

about the Doctor.

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

are being told to stay indoors until the storm passes.

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

with more than two feet of snow and 50 mile an hour winds.

We've got a special report from two kids in Washington.

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

from these stairs all the way down to here.

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!

And, right now BBC journalist Laura Bicker is in the US Capital

of Washington, and she sent us this update on how the storm

is developing there.

This is a city on shutdown.

Restaurants, bars, supermarkets, everything is closed as the city

hunkers down for the worst of this blizzard.

Over the next few hours they are expecting several inches

of snow to fall.

In fact forecasters have been saying this could be one of the worst

storms to hit the nation's capital in a century.

This is a slow-moving storm, it is expected to last all the way

through Saturday and into Sunday.

Certainly that is what people, forecasters and the officials,

are worried about.

They're worried about the accumulation of snow.

The roads have been cleared, people were told to be home by three

o'clock and to hunker down for the full duration of the storm.

People are being told just not to drive, to stay at home

until this storm passes.

People in charge of the biggest film awards in the world,

have promised to make big changes after being criticised

for nominating only white actors, two years in a row.

The Academy, who run the Oscars, say they will double the number

of female and minority members over the next four years.

Members vote for people they think should get an Oscar so by having

more non-white members it's hoped more non-white actors and filmmakers

will be nominated.

Some actors are so disappointed with this years white-only list

of nominations, that they will not be attending the ceremony next

month.

Next to a team in London using crime-fighting science to stop

dog poo on the city streets.

Ricky has this one.

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.

Tennis and Andy Murray is through to the fourth

round of the Australian Open after beating Portugal's 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.

Doctor Who's head writer and executive producer -

Steven Moffat - is leaving the show.

His last episode will go out in spring next year.

That's all from me, Newsround's back right here tomorrow morning.

Goodbye.
