Ricky here with Tuesday's top stories coming up on Newsround.

The invention that could make your doing smarter and, the breath-taking

skills you need to win in this Championship.

First, Antarctica is the earth's coldest spot and a hugely important

place. What happens there can affect the rest of the world. There are

some big changes going on there. Scientists say six giant glassiers

are melting and they don't think they can be stopped. I've found out

why they are worried. Antarctica, the coldest place on

earth and land of frozen beauty. Behind this incredible landscape, a

huge change is occurring. These masses of ice in western Antarctica

are melting. One glassier here can be nearly as big as the UK. Over the

last 40 year, NASA scientists have used satellites, aeroplane, ships

and ground surveys to study the area and say that six glassiers here are

melting away and that nothing can be done to stop it.

It's due to climate change caused by people.

Scientists say we have burnt a lot of old, coal and gas and this has

been putting particularly carbon dioxide into the atmosphere. That's

warmed it and it's changed the way the atmosphere behaves. It's

starting to blow faster. The winds are getting stronger, particularly

around Antarctica. That is pushing warm water towards the continent.

It's eroding, it's melting the fronts of the glaciers. Scientists

say the radar shows there are no ridges to top them from retreating

further inland. Because they are melting, more water is flowing into

the ocean which is having an impact on global sea-levels. A danger to

animals and people living on low-lying land near the coast.

Some of the gl laciers is huge. If you were to stand on top of them,

there would be ice as far as the eye could see. If they melt, all the

that water will go into the ocean and raise sea-levels which is a

problem for cities on coastlines because they will have to cope with

that and make changes to the way they build their cities in the

future. The scientists behind the research say the situation is a

major concern, but they say it could take hundreds of years for the

effects to be felt. We are talking about your doings

next and how smart they are. You have been telling us on the website

how clever your pets are and the tricks they can do. Thanks to a

group of students in America, your doings could soon be getting even

smarter thanks to a brand-new invention. We sent Martin off to

sniff this one out! What is the clevers thing you have taught your

doing to do? Beth in Solihull says her doing can roll over and catch a

ball in the air and Katie from Cape Town in South Africa told us that

her doing can open doors. Two students in America think they

may have found a way to make doings even smarter.

They have invented this digital feeder which rewards doings with

treats if they tap censors in the correct order. The instructions are

easy. Touch any pad and then it gets reward. It learns over time that if

it touches a pad it will get a reward. Once they have got that bit,

you make it a bit tougher and make them touch a specific pad and maybe

pads in order or we give them a cue, and it's your voice saying, "press

the left one". Doings are able to remember different instructions and

can work out challenges before the rewards are even given. Sit. How do

you do. The inventors say it's not stressful for dogs and only becomes

more challenges the more t used. So maybe you could try teaching your

doing new tricks. You never know, it could be smarter than you think.

Sport and Tottenham have sacked manager Tim Sherwood after the club

finished sixth in the Premier League. He only took the job in

December and signed what deal to the end of next season. Next to the

Championship that's in a glass of its own. Every year, more than 20

people take part in the glass-blowing Championships in

Finland. They have to try and create the biggest cylinder or plate in

under six minutes. Yosef from Hungary blew away the competition

with this breath-taking skill. Finally, get online and tell us if

your smartphones and tablets keep you up at night. According to

scientists, certain gadgets release a blue light which can confuse the

brain and make us stay up lighter, which may have an impact on our

sleep patterns due to the body clocks. Join me later. Bye.
