Good morning.

Jenny here with news of a record breaking space rover

on the way plus...

We want you to send us your super handshakes and high fives.

Keep watching.

First this morning to a record breaking space robot.

The Mars Rover, Opportunity, sent up to the red planet

by American space agency Nasa ten years ago, has now travelled further

than any other craft.

Nasa scientists say it was only supposed to travel half a mile

from its landing site originally, but has now clocked up 25 miles.

It broke the previous record of 24.2 miles, held by

Russia's Lunokhod two moon rover.

Next to a scientific study that claims fist bumping is

healthier than a handshake.

Researchers at Aberystwyth University say

the traditional handshake is the most unhygienic way to say hello.

They used rubber gloves covered in bacteria to test different greetings

and discovered it passes on 90% more germs than fist bumping.

They say it could change the way we say hello.

We're hoping that with the results of these experiments, people will

realise that handshakes can transfer quite a lot of bacteria between

people and that it might start becoming more socially acceptable

to fist bump or high-five.

Not just your mates.

Well, that got us thinking and we want you to send us videos of what

you think is the way to say hello.

Head to the Newsround website to find out how to get involved.

Ricky and I have already had a go.

Hey. Hey, how are you doing?

See you later. Bye.

Now if you found some Lego washed up on a beach, you might

think it was just good luck.

But if hundreds of pieces started washing up on the sand you might

start to ask questions.

Well that's exactly what's been happening

in Cornwall over the last 17 years.

We sent Ayshah to investigate just what?s going on.

I think I have found something.

A piece of plastic, false alarm.

This is Perranporth in Cornwall, one of the many beaches along this

coastline where Lego has been found.

Maggie, Charlie, Lily and Laura have been

on the search for bits of Lego all summer.

These are some of the Lego pieces found on Cornwall's beaches.

Laura, you found some, which ones?

I found all of them apart from this.

How long could it take you to find some of the Lego pieces?

It can take quite a while.

But you normally come across them by accident.

It hasn't just been washing up in the past few weeks,

it has been going on 17 years.

On the 13th of February 1997, a container ship called the Tokyo

Express left Rotterdam for New York in America.

When the boat was 20 miles of Land's End at the tip of Cornwall, it was

hit by a freak wave and tilted 60 degrees one way and 40 degrees back.

As a result, 62 containers fell overboard, one was carrying 5

million pieces of Lego.

Rob is a marine biologist and studies the movement

of ocean waves and currents.

It was during a storm, it would be mixed up

and spread around, spread out.

Some of it will have washed onto the beach but some will stay

in the ocean for years.

A huge ocean current goes around the UK, which will take them

around the world.

It is fun to fine Lego on the beach but can pose

It is fun to find Lego on the beach but can pose

a risk to wildlife, especially sea birds because it is dangerous.

I haven't found any yet but there is still time before it is dark.

In the Commonwealth Games England's Adam Gemilli grabbed

his first major medal in the final of the men's 100m last night.

The race was missing favourites Usain Bolt and Yohan Blake

but it was their fellow Jamaican Keymar Bailey Cole who

finished first in ten seconds flat.

Gemili's grabbed an impressive second place, something he was

pretty pleased with.

There is so much progression that goes into running ten seconds, it is

There is so much preparation that goes into running ten seconds, it is

not as easy as people think. I have a great team behind me. I can't

believe it, my first time representing England, I am so happy.

But Para-athlete Libby Clegg was the star of the night.

She won Scotland's first gold medal on the track in the T12 100m.

It meant this is now Scotland's most successful Commonwealth Games ever.

Earlier in the day, Alex Marshall and Paul Foster won

gold in the bowls.

That's all from me, Newsround's back right here in about half an hour.
