Hi, Catherine.

So what's the story about today?

Story down is about a gift from Mother Nature who I love gift.

So Okay, well lets him.

Or from this BBC World Service report, U.

S.

And British scientists have created a plastic digesting enzyme that can help in the fight against plastic pollution.

They've made an improved version of a natural enzyme that's evolved.

The ability to feed on plastic tests showed that the new engineered protein could break down one of the most popular forms of plastic widely used by the food and drinks industry.

So plastic pollution is a massive problem around the world is everybody's talking about it.

At the moment.

There's potentially some good news that British and American scientists may have found a solution to pollution from some types of plastic.

They discovered an enzyme on a Japanese recycling site.

They've done some work on it in the lab, and they believe that they could make this enzyme break down some of some very common plastics so that instead of taking hundreds of years, Teoh break down completely.

That process could be considerably speeded up by this enzyme.

So potentially a really big impact on plastic pollution Sounds fantastic.

Well, we've got three words and expressions that you can use to talk about this story.

What have we got for them, Catherine?

We have inadvertently devour on a Shirin inadvertently devour and usher in.

Okay, let's have a look at our first headline then, please.

Okay, we have the daily beast.

The headline is scientists inadvertently create mutant plastic eating enzyme inadvertently a Nintendo.

Chinna Lee.

Where does that word come from?

Okay, it comes originally from Latin.

The Latin word advert Terra means pay attention to.

But for this word, we have the prefix in, which gives it an opposite meaning.

So it means without paying attention to we add el y at the end to make it into an adverb form.

So without paying attention to Oh, like our colleague Key, who took the keys to the camera cupboard in his pocket last night inadvertently, he didn't know he had them.

We didn't know he had them.

We're looking for the camera cupboard key today.

Everybody was panicking and looking in 11th everywhere they could.

He came in.

We said, You see, in the keys K, he looked at his pockets on.

So Sorry, everybody there they were.

Yeah, yeah, Accidentally, without realizing inadvertently.

So because it's in adverse Antley, that means without paying attention, does that mean that paying attention is add vertically?

Dad, wouldn't it be good if that were true?

Oh, have I inadvertently made a mistake?

Unfortunately, you have.

So yet the opposite of inadvertently isn't advert.

Certainly it is something like knowingly, deliberately or purposely when you do something and you're aware that you did it.

I see well before we inadvertently bore our listeners talking too much about this.

Let's move on to our second headline.

Okay, so let's look at New Atlas.

The headline is, can this plastic eating enzyme devour our pet pollution problem Devour?

Eat eagerly.

Yes, it eagerly so again from Latin.

If you eat something really fast, you eat a lot of it.

Is it almost like an animal?

You know, an animal in it which is found in food on What's it All of it as quickly as possible to make anybody.

Nobody has can eat this food like rob with biscuit like rob with basis.

Admittedly, me with pizza I mean, can't get near you.

You're not gonna share.

It's all going down really, really quickly.

That's right.

Yeah, yes, it quickly and very, very eagerly.

But I've heard the phrase The building was devoured by fire Network, so devour is originally and its first meeting has to do with eating food.

But anything that gets kind of consumed or used or destroyed quickly on totally we can use this word devour.

So if you like to read a lot of books, for example, you can say I devour three novels a week or if your telephone, your phone mobile phone uses a lot of data, you can say my phone devours data so it's using or destroying anything quickly.

Okay, and it's kind of idiomatic in that way.

Exactly.

Yes, well, let's hope that our listeners have devoured that information, and we'll move on to our third and final headline.

Great.

So ITV news.

The headline is new plastic eating protein could usher in recycling revolution ushered in cause and activity or process to start.

Yes.

Is this anything to do with the artist?

Usher the singer?

Nothing whatsoever.

As far as I'm aware, it's just a think of coincidence that he's got the same name unless he had.

It has a job in a cinema showing people where they're supposed to sit.

So if you go to the cinema or the theatre, it's really dark.

There's often a person there with a torch flashlight.

We will show you where your seat is.

So the idea of showing a direction all kind of helping something toe happen in a particular way We have.

We also use Usher is a job at a wedding.

The person that shows people where they're going to sit is called an usher, and it's strongly connected with periods of time isn't or sort of things that have a profound change, right?

So this idea of change in movement or in showing direction and things that are going to happen if I am if you if something ushers something in it marks a period of great change is the start of a big change, so we could we could say that the invention of the World Wide Web.

OSHA din The Digital revolution This thing was the first thing that happened the World Wide Web, and now everything is different.

So what they're saying about this head, the headline is saying that this new plastic eating protein could usher in could signal the start off the recycling revolution.

This one thing happens after that.

Everything is going to be different.

Wonderful.

Thank you for clearing that up.

Now let's usher in our own Facebook challenge.

This morning we posted on Facebook.

Scientists have created a protein that can break down Plastic breakdown is a verb with many meanings.

Which of the following is not a meaning of breakdown?

A.

Stop working or functioning?

Be lose control of one's feelings.

See suddenly begin something or D separate into component parts.

How did they do?

Katherine?

You didn't really catch many people out.

I'm pleased to say, Don, I never dio eso.

We've got a pretty much clean sweep here.

Almost everybody, said Sisi, doesn't mean breakdown as a well done to mystery Abdullah Reserve Velasco, a Braille.

Everybody else you got that right, including Kaihori can echo Tanaka, who said See, is incorrect.

Then what's the right phrase over for C Town.

So again something Ah, well, that would be in many context.

We can use the phrase of Web break into.

For example, they suddenly broke into song.

Here we go, three for dad at that You go.

Thank you very much for clearing that up.

Now, could you please recap the vocabulary?

Of course.

We had inadvertently on intentionally devour eat eagerly on a Shirin cause and activity or protest to start.

Thank you.
