Hello and welcome to Newsround with me -

Live this Saturday afternoon - keep watching for this.

Find out why Justin Bieber has made chart history.

I am taking a look at all the latest technology here in Las Vegas

and I will be finding out how this alarm clock wakes you up

First to Australia where a massive bushfire has destroyed more

It's one of the worst fires of the Australian summer so far

The fire has been fuelled by winds, which has meant around 500 square

Firefighters have been working 24 hours a day to try to bring

Secret agents in America have arrested someone who planned

Bo and Sunny are Portuguese water dogs.

They were a present to Sasha and Malia, President Obama's

daughters, when he won the election in 2008.

This week, Ricky's been in Las Vegas, America,

at the biggest gadget show in the world.

Here's his round-up of some of the weirdest tech that he's seen.

So, this sofa has been specially adapted to move to coincide

with the movement of the video game. Oh!

So it has got special pads underneath each leg and they got up

and down depending on what you are doing in the actual game.

19-year-old Guillaume designed this alarm clock that wakes you up

He came up with the idea and created this very first model

Each cartridge has a different scent.

When it is time for your alarm to go off, the fan inside pushes the smell

This one smells like a coffee chocolate.

That's smells like the sea, like holiday smell.

That's what I would like to wake up to.

Now if you are like me and you are someone who loses your

umbrella all the time then this could be for you.

Inside this umbrella, there is a chip which connects

to your phone and it can tell if you're walking away

from your umbrella so it sends you an alert to tell you,

And if you are not a fan of doing the housework, then this

could be your thing, a robot that does all the hoovering.

We have also got robots to clean windows too.

This robot is meant to help patients in hospitals to relax.

If you cannot get a real pet into a hospital, then you can use

this robot and it responds to you whenever you stroke

it - it moves around. It is a bit like having a real pet.

So there you have it, all the weirdest tech

from the biggest gadget show in the world.

Head over to the Newsround website to see Ricky testing out a brand

If, like me, you love to dance then keep watching,

according to scientists, dinosaurs liked to bust a move too -

so I've been looking in to what gets a dino's body moving.

Have you ever try to impress anyone with your dance moves?

Well, you might have something in common with dinosaurs.

Scientists who study them say they used to perform a special bird

Huge scrapes have been found in rocks left by the animals

The patterns are similar to those left by puffins and ostriches

after they do their special mating dances.

The kind of dinosaurs that left these marks are still unknown

but the findings have brought scientists one step closer

That is the grooviest dinosaur I have ever seen!

To football now and Liverpool could only manage a draw

against League Two side Exeter in the third round of the FA Cup.

Brad Smith scored the Reds' second goal which means the two sides

Liverpool manager Jurgen Klopp fielded an inexperienced team

with three players making their debut.

Exeter manager Paul Tisdale is looking forward to the replay.

We have put on a really good show, it is a pity we could not have

played on a good surface because we had to play

the conditions today and it was very, very difficult

but we will get a chance to play on a plumb surface now at Anfield

Justin Bieber has made chart history by sitting at numbers one,

two and three in the UK singles chart!

The song Love Yourself is at the top, followed by Sorry,

How many elephants can you feed with a Christmas tree?

These three elephants in the Viennese Zoo were given

a healthy snack to get them through the cold winter months.

And their snack came from one of the tallest Christmas trees.

An 18-meter-tall and 90-year-old spruce tree.

A pretty big feast for anyone but for these elephants,

including two-year-old Iqua, it was a nutritious treat.

And before we go take a look at this dog, who just loves watching

the darts so much he wants to get involved and tries

And he's coming back now to try again!

That's all from me, Newsround's back tomorrow with lots more
