You're about to listen to a BBC podcast and maybe it's when I had a hand in.

I'm Tammy Walker and I produce podcasts for the BBC.

My role is to give new and diverse creators a voice with the opportunity to build a career.

That's the thing I love about podcasts.

You start with just a good idea, but then you have the space to see where it goes.

And doing that at the BBC means we can really run with the best stories

while developing the most unique audio talent.

So if you like what you hear, why not check out the huge range of

podcast we've got on BBC Sounds? The death was inevitable.

There was nothing we could do about the death. There was no surgery, there was no medication. There was nothing we could do to save his life.

But I thought there is something we can do to make his short life and his death productive.

And that was organi and tissue donation. That's author Sarah Gray, whose baby Thomas died shortly after birth.

Her family decided to donate his organs to science.

What they did was rare and exceptional and as we shall hear such

donations are incredibly useful for research and can help save many lives.

We'll come back to Sarah's story later, but the reason we reached out

to her in the first place was because of a question we received from a listener, who also

happens to be a kidney doctor in Brazil.

Hello, God Science, I'm Eduardo from Saint-Pélle. who also happens to be a kidney doctor in Brazil.

Hello, crowd science.

I'm Eduardo from Sao Paulo, Brazil,

and I'd like to know how far are we from making artificial human organs?
