Hi, I'm Hayley.

This is Newsround and we've got

loads of great stuff

coming up for you.

We look at why the US

is shivering right now.

Check out these skills.

It is winter, so we probably

shouldn't be surprised that it's

pretty cold outside.

But in parts of America,

the temperatures are

much more drastic.

Whitney's got this.

How chilly does this look?

The US is currently on its tenth day

of record-breaking cold

temperatures, which began around

Christmas.

Some places have been

been colder than Mars.

That's so cold that weather experts

have started describing

it as a bomb cyclone.

It certainly sounds dramatic.

It's caused when air pressure drops

quickly and means even more

freezing temperatures,

blizzards and dangerously icy winds

- strong enough to bring down trees.

Some people say it could feel

like a winter hurricane.

Schools have been closed

in areas around New York

which are likely to be hardest hit

by heavy snow.

It could be more than

25 centimetres deep.

Big cities in the north-east

like Boston also face

problems, with big blizzards

on the way there too.

But for some people in Tallahassee

in Florida, the snowy weather's

been a bit of a novelty.

They've only had a little compared

to the other side of the country,

and most of it melted when it hit

the ground, but it's the first time

they've seen snow in 28 years.

Do you worry about how

you look or how many likes

you get on social media?

Well, a new report out today says

at secondary school this becomes

a lot more important to kids.

Here's what you guys

had to say about it.

The biggest change is probably how

much people use it and how many

people actually use it

in the school.

People think it's a lot cooler

to actually use social media now,

rather than in year six.

Social media really impacts

you and the way you look

and want to come across,

especially in secondary school.

There is a lot more pressure

in secondary school to get

likes and followers.

In secondary school I think people

are a lot more conscious

of what they post and how it looks

and just the things

that they say or do on it.

For me, it is not that much

of a pressure, because I don't

really care what people think.

Everybody in high school,

if they see you and they see

you on Instagram, they try

to follow you.

Not everybody, but most people,

because they want to get followers.

In secondary school there is a lot

of insecurity about your looks

and the way you dress and come

to school, because on social

media it is kind of shown

how you should look.

People think that you need the likes

to get fame in the school.

There is more pressure to be

looking good on social

media when you are older,

because you have got more

pressure on your appearance,

people think they should look better

when they are older.

And there's loads more

information on social

media at this website -

Now, take a look at this.

This is world champion

footballing freestyler,

Liv Cooke showing off just good

she is with a football.

And she's doing it while

on a train - sitting down.

Wow!

Amazing!

Scientists in America have

been putting sea turtles

on treadmills and then

testing their swimming strength.

It's not cruel - it's

to find out whether

the distance new born sea turtles

have to crawl when first born

affects their ability

to swim in the sea.

Amazingly they showed no

signs of tiring at all.

That's Turtely awesome!

You're about to be overwhelmed

by cuteness - you ready?

Eight cheetah cubs have been born

in at St Louis Zoo in America.

They were born back in November

but this is the first video of them.

The Zoo says mum and her cubs

are doing really well.

Just enough time to tell you to head

online, where you can find out

how your street lights could be

powered by dog poo.

I'm not even joking.

Good job it's not smellyvision.

Plus check out the brand new coins

just released for you to spend!

That's it from

Newsround for tonight.
