Now, let's hear more about the story.

A cancer vaccine by 2030. The husband and wife team who worked on the covid job say the same technology could be used to treat cancer.

These vaccines tell the cells to produce a protein that can fight tumors.

The trials are in the early stages, but results have been encouraging.

So far, You ve been looking at the headline, shine, what's the vocabulary?

We have crack hailed and pioneers.

This is news review from BBC, learning English.

Let's have a look at our 1st headline.

OK? This one is from BBC Biotech Could covied vaccine technology crack cancer?

And so the headline is asking whether the technology that was used to develop covid vaccines could also help in finding a vaccine or cure for cancer.

The company that's working on this is by on Tech, but the word we're looking at is crack.

Now, I know this word crack.

I can crack an egg or cracker plate means it breaks.

What's the connection? OK? So those examples are physical examples, literally examples of breaking something.

But here, crack means to solve a problem, to find a solution to a problem.

Ah, OK. So it's this technology that could solve or crack the problem of cancer.

Um, can we use crack in any other way, like this?

Yeah, so we can talk about the police crack in a case.

So this means they solve the case, they solve the crime.

Or detective like Sherlock, can crack a code, so that means he finds a solution, he works out what the code means.

Okay, well, I think we've cracked this explanation for our audience.

Let's look at that again. Let's have a look at our next headline.

This one's from the evening Standard Cancer Vaccine Being Hailed by Leading covid scientists.

The headline is saying that A vaccine for cancer is being hailed by leading covied scientists.

Leading covied scientists are the scientists who develop the covied vaccine.

But we're looking at the word hailed.

What can you tell us? Yes.

So hale here is a verb, and it means to praise or approve a person or an achievement, and normally in a very public way.

Yes. So the headline is saying, there's a lot of praise for this potential cancer vaccine.

It is hailed as a possible cure.

And it's the scientist themselves who are praising themselves exactly.

And this but hail is usually used in a passive form in headlines, and that's because the thing that is hailed is often more important than the people who are praising.

Yeah? And so we can say that a film is hailed as a masterpiece, or a company profits are hailed as a sign of a success.

We hear this used a lot in news, but do we use hail in our everyday English?

Not really. It's quite a dramatic word, so it's not really used in informal chat.

It's more in headlines, and it has more impact because of that.

Well, I'm going to hail that explanation is a great success.

Let's have a look at it one more time.

Time for our next headline, please.

Okay? This one is from The Times Expect cancer vaccine by 2030, say Covied Pioneers.

The headline says, we can expect a cancer vaccine by 2030.

The word we're looking at is pioneers.

Now, shown when I imagine pioneers, I can picture men with big beards and rifles walking off into the wilderness to claim a new land.

What's the connection? I'm not sure if these scientists have big beards or look exactly like that, but I imagine not.

But you're right. A pioneer was someone who explored or settled in a new area, particularly the US.

But nowadays, pioneer is often used to mean a person

who is 1st to develop or use something new.

OK? So by covied pioneers, we mean the 1st people to develop a vaccine for covied.

That's right. So we can use a pioneer in relation to a new method, a new technique, or an area of knowledge.

E.g., marie Curie was a pioneer in physics and chemistry because she discovered radioactivity.

And Steve Jobs was a technology pioneer.

Yes. And so the Covied vaccine pioneers are now hoping to become cancer vaccine pioneers.

Now, if I talk about my own life, I do a small piece of work that I think is really important.

I have a new idea for a program at BBC, learning English.

Am I-A pioneer? Well, you could kneel, but it sounds a bit grand.

You're saying that you're a very important person.

In normal conversation, it's more likely just to say that you developed something or you invented something new.

We've been looking at the word as a noun.

Yes, it's also a verb to pioneer, yes, so you can pioneer something.

Yeah. So E.G. BBC Learning English is almost 80 years old.

And 80 years ago we pioneered teaching English by radio.

But we weren't around then. No, we were.

Let's have a look at that again.

We've had crack find a solution to something hailed, praised and pioneers the 1st people to develop or use something.

I don't forget there's a quiz on our website, bbc learning english dot com.

Thank you for joining us. And goodbye, goodbye.
