It's Tuesday, we're live.

I'm Ricky.

On Newsround this hour, all the latest

from the Australian Open.

Weird weather in Egypt.

Erupting volcanoes.

Plus the floating bin that sucks up rubbish from the sea.

Also, we'll show you this deer's lucky escape.

First this morning to Southern Africa where there are worries that

about 14 million people could go hungry because of a drought.

The United Nations world food programme says that with little

or no rain expected things could could get even worse.

Problems have been caused by a poor harvest last year

because of really dry weather.

And there are worries that the same could happen this year.

It's summer in Australia which, unfortunately, in some areas

of the country means bushfires start easily and can get quickly

out of control.

However, luckily for residents in Victoria, a state

in the South East of Australia, this fire was brought under control,

but not before it destroyed a house.

Residents have been told to remain close to shelter in case

conditions change again.

A sandstorm hit Egypt yesterday, it turned the sky yellow over

the capital city Cairo, blotting out the sun

and limiting visibility.

Some of the country's major sea-ports had to be closed and some

flights couldn't land.

The weather is expected to improve today.

In Mexico, in north America, one the country's tallest

volcanoes has erupted.

The Popocatepetl volcano threw ash and gas nearly two

kilometres into sky.

Those monitoring the site are warning people living nearby

to be ready to leave because the volcano is showing

signs of activity.

Now if you were feeling a bit blue yesterday...

You weren't the only one.

Scientists say that third Monday in January is the most miserable day

of the year.

So we've been asking what makes you happy on the Newsround website.

Thanks for sending all of those in.

And now to these two surfers in Australia who have developed

a new invention which is designed to collect rubbish in the oceans.

Here's Leah with all the details.

Rubbish in the ocean can cause real problems for sea-life.

Eight million tonnes of plastic goes into the world's oceans every year

and experts say it poses serious risks, especially to birds

and animals like turtles, dolphins and whales.

A pair of surfers from Perth, Australia, have invented a nifty

tool which they hope might help to reduce the problem.

Pete and Andrew have created the seabin.

Its special design means that rubbish floating on the water

is sucked into the bin.

The lining inside is then lifted out and the rubbish

disposed of properly.

Just now the seabin is used in ports and harbours which are areas

that the tide and winds push rubbish in to.

The guys are hoping to raise money for the project

online through crowd-funding.

A process where people can give money to support things

they are interested in.

Good luck guys.

To tennis now and the Australian Open is well underway.

Johanna Konta, British number one beat seven-time grand slam champion

Venus Williams in straight sets.

Konta said she had to bring her best to beat the 35-year-old American.

Venus as a champion has so much experience and just so much

knowledge about the game, that even if she is playing with one

leg out, you have really got to take care of things

on your own because...

No, she is an incredible player and I have all the respect

for her in the world.

Andy Murray also won in straight sets against German

teenager Alexander Zverev.

He'll now face Australian Sam Groth, holder of the game's fastest

serve, on Thursday.

Obviously, he will have the crowd behind him as well.

He is a very competitive guy too, he fights extremely hard,

he has a great attitude and, will make it tough for me

because he has a different game style to a lot of the players now.

But, yeah, I will be ready for that.

To football now and Swansea are back to winning ways and out

of the relegation zone.

Thanks to a 1-0 win against Watford.

Defender Ashley Williams scored with a header.

The Swans' new manager Francesco Guidolin watched

on from the stands.

Obviously, he is coming into a strange environment,

he is coming to a strange club where he is probably not

going to know a huge amount of the players.

He will have first hand knowledge of them tonight,

Not just the players who play today but the rest of the players

in the squad as well and what they can offer.

I think we are all looking forward to working with him

and we are looking forward now to a positive end to the season.

A three year old deer was rescued by firemen from the icy water

of the Notec River in Poland.

Once the deer was successfully back on dry land the firemen tried

to warm it up by covering the deer in blankets and straw.

They also lit fires to keep it cosy.

A lucky escape.

In Peru in South America they've come up with an interesting way

of catching people who dump rubbish.

They've trained ten vultures to monitor the skies

above the capital city, Lima.

They're wearing cameras fitted with tracking systems to try to help

authorities find out who is leaving rubbish in places they're

not supposed to.

That's all from me, Newsround's back this afternoon at 4.20pm with Jenny.

Have a great day.
