0:00:03 > 0:00:04It's Tuesday, we're live.
0:00:04 > 0:00:06I'm Ricky.
0:00:06 > 0:00:08On Newsround this hour, all the latest
0:00:08 > 0:00:10from the Australian Open.
0:00:10 > 0:00:15Weird weather in Egypt.
0:00:15 > 0:00:21Erupting volcanoes.
0:00:21 > 0:00:22Plus the floating bin that sucks up rubbish from the sea.
0:00:23 > 0:00:31Also, we'll show you this deer's lucky escape.
0:00:31 > 0:00:34First this morning to Southern Africa where there are worries that
0:00:34 > 0:00:38about 14 million people could go hungry because of a drought.
0:00:38 > 0:00:42The United Nations world food programme says that with little
0:00:42 > 0:00:46or no rain expected things could could get even worse.
0:00:46 > 0:00:49Problems have been caused by a poor harvest last year
0:00:49 > 0:00:51because of really dry weather.
0:00:51 > 0:00:55And there are worries that the same could happen this year.
0:00:55 > 0:00:58It's summer in Australia which, unfortunately, in some areas
0:00:58 > 0:01:01of the country means bushfires start easily and can get quickly
0:01:01 > 0:01:03out of control.
0:01:03 > 0:01:05However, luckily for residents in Victoria, a state
0:01:05 > 0:01:08in the South East of Australia, this fire was brought under control,
0:01:08 > 0:01:10but not before it destroyed a house.
0:01:10 > 0:01:14Residents have been told to remain close to shelter in case
0:01:14 > 0:01:17conditions change again.
0:01:17 > 0:01:20A sandstorm hit Egypt yesterday, it turned the sky yellow over
0:01:20 > 0:01:22the capital city Cairo, blotting out the sun
0:01:22 > 0:01:25and limiting visibility.
0:01:25 > 0:01:28Some of the country's major sea-ports had to be closed and some
0:01:28 > 0:01:32flights couldn't land.
0:01:32 > 0:01:35The weather is expected to improve today.
0:01:35 > 0:01:37In Mexico, in north America, one the country's tallest
0:01:37 > 0:01:40volcanoes has erupted.
0:01:40 > 0:01:43The Popocatepetl volcano threw ash and gas nearly two
0:01:43 > 0:01:45kilometres into sky.
0:01:45 > 0:01:48Those monitoring the site are warning people living nearby
0:01:48 > 0:01:50to be ready to leave because the volcano is showing
0:01:50 > 0:01:54signs of activity.
0:01:54 > 0:01:56Now if you were feeling a bit blue yesterday...
0:01:56 > 0:01:58You weren't the only one.
0:01:58 > 0:02:01Scientists say that third Monday in January is the most miserable day
0:02:01 > 0:02:02of the year.
0:02:02 > 0:02:12So we've been asking what makes you happy on the Newsround website.
0:02:24 > 0:02:29Thanks for sending all of those in.
0:02:29 > 0:02:32And now to these two surfers in Australia who have developed
0:02:32 > 0:02:35a new invention which is designed to collect rubbish in the oceans.
0:02:35 > 0:02:37Here's Leah with all the details.
0:02:37 > 0:02:41Rubbish in the ocean can cause real problems for sea-life.
0:02:41 > 0:02:45Eight million tonnes of plastic goes into the world's oceans every year
0:02:45 > 0:02:50and experts say it poses serious risks, especially to birds
0:02:50 > 0:02:54and animals like turtles, dolphins and whales.
0:02:54 > 0:02:58A pair of surfers from Perth, Australia, have invented a nifty
0:02:58 > 0:03:02tool which they hope might help to reduce the problem.
0:03:02 > 0:03:05Pete and Andrew have created the seabin.
0:03:05 > 0:03:11Its special design means that rubbish floating on the water
0:03:11 > 0:03:12is sucked into the bin.
0:03:12 > 0:03:15The lining inside is then lifted out and the rubbish
0:03:15 > 0:03:17disposed of properly.
0:03:17 > 0:03:20Just now the seabin is used in ports and harbours which are areas
0:03:20 > 0:03:25that the tide and winds push rubbish in to.
0:03:25 > 0:03:27The guys are hoping to raise money for the project
0:03:27 > 0:03:29online through crowd-funding.
0:03:29 > 0:03:31A process where people can give money to support things
0:03:31 > 0:03:33they are interested in.
0:03:33 > 0:03:40Good luck guys.
0:03:40 > 0:03:42To tennis now and the Australian Open is well underway.
0:03:42 > 0:03:44Johanna Konta, British number one beat seven-time grand slam champion
0:03:44 > 0:03:46Venus Williams in straight sets.
0:03:46 > 0:03:50Konta said she had to bring her best to beat the 35-year-old American.
0:03:50 > 0:03:53Venus as a champion has so much experience and just so much
0:03:53 > 0:03:58knowledge about the game, that even if she is playing with one
0:03:58 > 0:04:01leg out, you have really got to take care of things
0:04:01 > 0:04:04on your own because...
0:04:04 > 0:04:07No, she is an incredible player and I have all the respect
0:04:07 > 0:04:11for her in the world.
0:04:11 > 0:04:14Andy Murray also won in straight sets against German
0:04:14 > 0:04:15teenager Alexander Zverev.
0:04:15 > 0:04:17He'll now face Australian Sam Groth, holder of the game's fastest
0:04:17 > 0:04:20serve, on Thursday.
0:04:20 > 0:04:22Obviously, he will have the crowd behind him as well.
0:04:22 > 0:04:24He is a very competitive guy too, he fights extremely hard,
0:04:24 > 0:04:29he has a great attitude and, will make it tough for me
0:04:29 > 0:04:33because he has a different game style to a lot of the players now.
0:04:33 > 0:04:38But, yeah, I will be ready for that.
0:04:38 > 0:04:41To football now and Swansea are back to winning ways and out
0:04:41 > 0:04:42of the relegation zone.
0:04:42 > 0:04:44Thanks to a 1-0 win against Watford.
0:04:44 > 0:04:47Defender Ashley Williams scored with a header.
0:04:47 > 0:04:49The Swans' new manager Francesco Guidolin watched
0:04:49 > 0:04:51on from the stands.
0:04:51 > 0:04:53Obviously, he is coming into a strange environment,
0:04:53 > 0:04:56he is coming to a strange club where he is probably not
0:04:56 > 0:04:58going to know a huge amount of the players.
0:04:58 > 0:05:02He will have first hand knowledge of them tonight,
0:05:02 > 0:05:05Not just the players who play today but the rest of the players
0:05:05 > 0:05:08in the squad as well and what they can offer.
0:05:08 > 0:05:11I think we are all looking forward to working with him
0:05:11 > 0:05:15and we are looking forward now to a positive end to the season.
0:05:15 > 0:05:19A three year old deer was rescued by firemen from the icy water
0:05:19 > 0:05:22of the Notec River in Poland.
0:05:22 > 0:05:26Once the deer was successfully back on dry land the firemen tried
0:05:26 > 0:05:29to warm it up by covering the deer in blankets and straw.
0:05:29 > 0:05:31They also lit fires to keep it cosy.
0:05:31 > 0:05:33A lucky escape.
0:05:33 > 0:05:36In Peru in South America they've come up with an interesting way
0:05:36 > 0:05:40of catching people who dump rubbish.
0:05:40 > 0:05:41They've trained ten vultures to monitor the skies
0:05:41 > 0:05:43above the capital city, Lima.
0:05:43 > 0:05:46They're wearing cameras fitted with tracking systems to try to help
0:05:46 > 0:05:48authorities find out who is leaving rubbish in places they're
0:05:48 > 0:05:51not supposed to.
0:05:51 > 0:05:55That's all from me, Newsround's back this afternoon at 4.20pm with Jenny.
0:05:55 > 0:06:00Have a great day.
